Description

Technical Field

[0001] This application belongs to the field of core encapsulation, and specifically relates to a core encapsulation device and method. Background Technology

[0002] Core studies are of paramount importance in fields such as geological exploration and oil extraction. To better preserve the original state of cores and the various geological information they contain, effective core sealing treatment is necessary. Among numerous sealing methods, plastic film sealing is a relatively economical and practical approach.

[0003] Typically, plastic film sealing involves placing the core on a suitable support and then using a film-winding device to gradually wrap the plastic film around the core's outer wall. However, when cores are retrieved from the formation, the fracture ends are often not smooth but rather have sharp corners. These sharp corners can damage the plastic film during wrapping. When the film reaches these sharp corners, the protruding and sharp nature of the corners creates concentrated stress during and after wrapping, easily puncturing the plastic film. Once the film is punctured, external substances such as air and moisture can easily penetrate the core, altering its physical and chemical properties and affecting subsequent analysis and research results. Furthermore, if the film is damaged, substances inside the core may leak out, causing contamination and data loss.

[0004] In summary, how to solve the problem of damage to the plastic film caused by the sharp corners at both ends of the rock core, and achieve effective sealing and preservation of the rock core, has become a key issue that urgently needs to be addressed in the current field of rock core packaging technology. Summary of the Invention

[0005] In view of the above analysis, the present invention aims to provide a core packaging device and packaging method to solve one or more of the above-mentioned problems existing in the prior art.

[0006] The objective of this invention is achieved as follows:

[0007] On the one hand, a core packaging device is provided, comprising:

[0008] The first and second tracks are arranged linearly, with the first track and the second track having an intertwined interval. One end of the core can be attached to the first track, and the other end can be attached to the second track.

[0009] A film winding mechanism is disposed outside the second track. The winding starting position of the film winding mechanism is located at the winding interval and adjacent to the second track. The film winding mechanism is used to wind a plastic film onto the outer wall of the core.

[0010] A pushing mechanism, set on the first track, is used to move the end cap to the end of the rock core and fit it onto the rock core. The end cap can press against the tail end of the film after the rock core is wound with film. The tail end of the film is also located within the winding interval and adjacent to the first track.

[0011] The lifting mechanism, located below the winding interval, is configured to lift the end of the rock core near the first track by a predetermined angle after the rock core is wound with film. The pushing mechanism is collinear with the lifted rock core.

[0012] The rotary moving mechanism, located on one side of the second track, is configured to rotate the rock core pushed by the pushing mechanism by 180 degrees, move the rock core to dock with the pushing mechanism, and cooperate with the pushing mechanism to simultaneously support both ends of the rock core and move the rock core synchronously.

[0013] Furthermore, the film winding mechanism includes:

[0014] Multiple winding motors, wherein the rotating end of each winding motor is connected to a roller;

[0015] A rotating ring has an annular groove on its side wall. Multiple winding motors are arranged around the outside of the rotating ring, and the rollers are in rolling friction connection with the annular groove. The multiple rollers limit the position of the rotating ring.

[0016] A winding support is connected to the end wall of the rotating ring, and a film roll is rotatably connected to the winding support.

[0017] Furthermore, the pushing mechanism includes a pushing motor and a pushing clamp, the pushing clamp having a clamping groove corresponding to the shape of the end cap.

[0018] Furthermore, a flared rubber ring is connected to the inner wall of the end cap, and the tail of the end cap has a hexagonal structure.

[0019] Furthermore, the lifting mechanism includes a lifting seat, a lifting slide rail, a sliding platform, a telescopic motor, a telescopic gear, a telescopic toothed plate, a top platform, and a guide rod; the lifting slide rail is connected to the lifting seat, the sliding platform is slidably connected to the lifting slide rail, the telescopic motor is connected to the sliding platform, the telescopic gear is connected to the telescopic motor, the guide rod is vertically connected to the sliding platform, the top platform is slidably connected to the guide rod, the telescopic toothed plate is connected to the top platform, the sliding platform has a telescopic groove corresponding to the position of the telescopic toothed plate, the telescopic gear meshes with the telescopic toothed plate, and the sliding platform moves along the length direction of the core along the lifting slide rail.

[0020] Furthermore, the end of the first track is provided with an opening for the top platform to move.

[0021] Furthermore, the rotary movement mechanism includes a rotary linear motor, a rotary push plate, a third track, and a rotary motor. The third track is parallel to and corresponding to the second track. The rotary motor is connected to the bottom of the third track. The rotary linear motor is located on one side of the third track. The rotary push plate is connected to the drive end of the rotary linear motor. The rotary linear motor can extend and retract along the third track. When the core is completely inserted into the third track, the rotary motor can drive the third track to rotate 180 degrees.

[0022] Furthermore, it also includes an infrared laser sensor, which is connected to the rotary pusher plate and is used to detect the distance between the core and the rotary pusher plate to determine whether the core has completely entered the third track.

[0023] Furthermore, it also includes a lifting motor, the bottom of which is connected to the lifting motor. When the core enters the third track, the height of the third track is lower than the height of the second track. When one end of the core is about to leave the third track and enter the second track, the height of the third track is higher than the height of the second track. After one end of the core enters the second track, the height of the third track returns to the initial height, which is lower than the height of the second track.

[0024] On the other hand, a core encapsulation method is also provided, which uses the aforementioned core encapsulation equipment to encapsulate the core.

[0025] Furthermore, the core encapsulation method includes the following steps:

[0026] The core is placed on the first track and the second track, with one end overlapping the first track and the other end overlapping the second track. The core is located near the winding start position of the film winding mechanism, which is located at the winding interval and adjacent to the second track.

[0027] Place one end of the plastic film tightly against the starting position of the core winding, start the film winding mechanism, and let it wind the plastic film onto the outer wall of the core at a stable speed and force. At the same time, the pushing mechanism starts the pushing action, which works in conjunction with the rotary moving mechanism. Both of them hold and fix the core and assist the core to move towards the second track, from one end of the core to the other. The core at both ends is not wound temporarily.

[0028] After the core is wrapped with film, the pushing mechanism and the rotary moving mechanism move the core toward the first track direction, so that it returns to the vicinity of the initial position and resets.

[0029] The lifting mechanism is activated, and the lifting mechanism uses the end of the second track as the rotation point to lift the end of the rock core close to the first track by a predetermined angle, so that sufficient space is formed between the rock core and the first track.

[0030] The pushing mechanism inserts the pre-prepared end cap through the gap formed after the lifting and connects it with the core. The end cap is then pressed against the end of the film after the core is wrapped with film.

[0031] The pushing mechanism pushes the core to the rotary moving mechanism. The rotary moving mechanism first rotates the core 180 degrees, then moves the core to dock with the pushing mechanism. Then, the rotary moving mechanism cooperates with the pushing mechanism to place one end of the core onto the first track and the other end onto the second track.

[0032] The end cap at the other end is inserted into the core via a pushing mechanism, thus sealing both ends of the core.

[0033] Compared with existing technologies, the core encapsulation equipment and method provided by this invention have a film winding mechanism whose winding starting position is located at the winding interval and adjacent to the second track. After the operator manually places one end of the film tightly against the core winding starting position, the film winding mechanism starts to wind the plastic film onto the outer wall of the core. Through its own operating mechanism, it performs film winding operations at a stable speed and force, ensuring that the film is evenly and tightly wound on the core surface, providing initial encapsulation for the core. At the start of film winding, the pushing mechanism begins its pushing action, cooperating with the rotary moving mechanism. The pushing mechanism and the rotary moving mechanism together hold and fix the core and assist the core in moving towards the second track, from one end of the core to the other, while leaving the core at both ends unwound, only winding the inner portions at both ends. After the core is wound with film, the pushing mechanism and the rotary moving mechanism move the core towards the first track. After resetting, the lifting mechanism raises the core to a predetermined height, creating a gap between it and the first track. The pushing mechanism then inserts a pre-prepared end cap through this gap into the core. At this point, the end cap presses against the tail end of the film after it has been wrapped around the core, thus securing the film tail end. The lifting mechanism is located below the winding interval. When the core is being wound with film and the end cap is ready to be inserted, the lifting mechanism activates. Using the end of the second track as a rotation point, it lifts the end of the core closest to the first track by a predetermined angle, creating sufficient space between the core and the first track so that the pushing mechanism can smoothly push the end cap to the core and complete the insertion operation. In the initial stage of film winding, the rotary moving mechanism and the pushing mechanism operate simultaneously, both contacting both ends of the core to hold and fix it. During film winding, the rotary moving mechanism not only fixes the core position but also works in conjunction with the pushing mechanism to move the core, ensuring the film is wound evenly from one end of the core to the other. After the pushing mechanism delivers the core, the rotary moving mechanism first rotates the core 180 degrees, then moves the core to align with the pushing mechanism. Next, working in conjunction with the pushing mechanism, one end of the core is placed on the first track, and the other end on the second track, completing the core's attitude adjustment and preparing it for the end cap to be placed on the other end. This combination of rotation and movement allows for precise position and attitude adjustment of the core at different operational stages, ensuring the smooth progress of the entire encapsulation process. The aforementioned end cap and film design successfully prevents damage to the plastic film from the core's sharp corners, ensuring the film is completely and tightly wrapped around the core's outer wall, achieving effective sealing and preservation of the core. This significantly reduces the risk of external air, moisture, and other substances intruding into the core, maintaining the stability of the core's physical and chemical properties, which is beneficial for subsequent analysis and research.

[0050] A specific embodiment of the present invention, such as Figures 1 to 6 As shown, a core packaging device is disclosed, comprising:

[0051] The first track 10 and the second track 11 are arranged linearly, with the first track 10 and the second track 11 having an intertwined interval. One end of the core can be attached to the first track 10, and the other end can be attached to the second track 11.

[0052] A film winding mechanism 30 is disposed outside the second track 11. The winding starting position of the film winding mechanism 30 is located at the winding interval and adjacent to the second track 11. The film winding mechanism 30 is used to wind a plastic film onto the outer wall of the core.

[0053] The pushing mechanism 20 is disposed on the first track 10 and is used to move the end cap 13 to the end of the rock core and fit it onto the rock core. The end cap 13 can be pressed against the tail end of the film after the rock core is wound with film. The tail end of the film is also located within the winding interval and adjacent to the first track 10.

[0054] The lifting mechanism 40 is located below the winding interval and is configured after the core is wound with film. It lifts the end of the core near the first track 10 by a predetermined angle with the end of the second track 11 as the rotation point. The pushing mechanism 20 is collinear with the lifted core.

[0055] The rotary moving mechanism 50 is located on one side of the second track 11 and is configured to rotate the rock core pushed by the pushing mechanism 20 by 180 degrees, move the rock core to dock with the pushing mechanism 20, and cooperate with the pushing mechanism 20 to simultaneously support and move the rock core at both ends.

[0056] In this embodiment, the winding starting position of the film winding mechanism 30 is located at the winding interval and adjacent to the second track 11. After manually pressing one end of the film tightly against the core winding starting position, the film winding mechanism 30 starts to wind the plastic film onto the outer wall of the core. Through its own operating mechanism, it performs film winding operations at a stable speed and force, ensuring that the film can be evenly and tightly wound on the core surface, providing initial encapsulation for the core. When film winding begins, the pushing mechanism 20 begins to push, cooperating with the rotary moving mechanism 50. The pushing mechanism 20 and the rotary moving mechanism 50 together hold and fix the core and assist the core in moving towards the second track 11, from one end of the core to the other, while leaving the core at both ends unwound, only winding the inner portion at both ends. After the core is wound with film, the pushing mechanism 20 and the rotary moving mechanism 50 move the core towards the first track 10. After resetting, the lifting mechanism 40 raises the core to a predetermined height, creating a gap between it and the first track 10. The pushing mechanism 20 then inserts the pre-prepared end cap 13 through this gap into the core. At this point, the end cap 13 presses against the tail end of the film after the core is wrapped, thus squeezing and fixing the film tail end. The lifting mechanism 40 is located below the winding interval. When the core is being wrapped with film and the end cap 13 is ready to be inserted into the core, the lifting mechanism 40 is activated. Using the end on the second track 11 as a rotation point, it lifts the end of the core closest to the first track 10 by a predetermined angle, creating sufficient space between the core and the first track 10 so that the pushing mechanism 20 can smoothly push the end cap 13 into the core and complete the insertion operation. In the initial stage of film winding, the rotary moving mechanism 50 and the pushing mechanism 20 operate simultaneously, both abutting against both ends of the core to hold and fix it. During the film winding process, the rotary moving mechanism 50 not only fixes the core position but also works in conjunction with the pushing mechanism 20 to move the core, ensuring the film is wound evenly from one end of the core to the other. After the pushing mechanism 20 pushes the core, the rotary moving mechanism 50 first rotates the core 180 degrees, then moves it to align with the pushing mechanism 20. Next, in conjunction with the pushing mechanism 20, it places one end of the core onto the first track 10 and the other end onto the second track 11, completing the core's posture adjustment and preparing for the installation of the end cap 13 at the other end of the core. Through the combination of rotation and movement functions, it achieves accurate position and posture adjustment of the core at different operational stages, ensuring the smooth progress of the entire encapsulation process.

[0057] In other words, the overall working process is as follows: First, the film is manually placed against the starting position of the core winding. The film winding mechanism 30 starts winding the film, and at the same time, the pushing mechanism 20 starts pushing. The rotary moving mechanism 50 works in conjunction with the pushing mechanism 20 to simultaneously abut against both ends of the core and hold them in place. The two mechanisms work together to move the core, so that the film is evenly wound from one end of the core to the other. After the winding of the tail end of the core is completed, both the pushing mechanism 20 and the rotary moving mechanism 50 are reset. Then, the end cap 13 is connected to the pushing mechanism 20, and the lifting mechanism 40 is controlled to lift the core, so that the core is slightly raised and there is a gap between it and the first track 10. The pushing mechanism 20 pushes the end cap 13 through the gap and inserts it into the core. The end cap 13 squeezes and fixes the film at the tail end of the core. Afterwards, once the pushing mechanism 20 pushes the core, the rotary moving mechanism 50 first rotates the core 180 degrees, then moves the core to align with the pushing mechanism 20. Next, in conjunction with the pushing mechanism 20, one end of the core is connected to the first track 10, and the other end to the second track 11. At this point, the core's posture adjustment is complete, preparing for the installation of the end cap 13. Finally, the pushing mechanism 20 inserts the end cap 13 into the core, sealing both ends and completing the core's storage.

[0058] The end cap 13 allows for the compression and fixation of the film's tail end. During core sealing, the tail end is typically unsecured after the plastic film is wrapped, making its fixation crucial. The compression action of the end cap 13 ensures a tight fit between the film tail end and the core, preventing loosening or lifting. This fixation method effectively prevents accidental tearing or tearing of the film due to instability at the tail end during subsequent operations or transportation. It ensures the integrity and sealing of the film across the entire core surface, further enhancing its protective effect and preventing external air, moisture, and other substances from penetrating the core through the film tail end. This maintains the stability of the core's physical and chemical properties, facilitating subsequent analysis and research.

[0059] To address the issue of sharp corners at both ends of the core sample, end caps 13 play a crucial sealing role. End caps 13 fit snugly over the core sample end, completely enclosing the sharp corners. This not only prevents potential accidental injury to personnel or other equipment from direct exposure of the sharp corners, but more importantly, effectively prevents secondary damage to the membrane during routine storage or handling. Even under minor external impacts or pressure, end caps 13 can withstand most of the force, thus protecting the internal membrane and the core sample from damage. Simultaneously, the sealing effect of end caps 13 creates a relatively enclosed space at the core sample end, further reducing the erosion caused by external environmental factors, extending the core's shelf life, and providing reliable protection for long-term storage and research.

[0060] In some embodiments, the film winding mechanism 30 includes:

[0061] Multiple winding motors 301, the rotating end of each winding motor 301 is connected to a roller 303;

[0062] A rotating ring 302 has an annular groove on its side wall. Multiple winding motors 301 are arranged around the outside of the rotating ring 302, and the rollers 303 are in rolling friction connection with the annular groove. The multiple rollers 303 limit the rotation ring 302.

[0063] A winding bracket 304 is connected to the end wall of the rotating ring 302, and a film roll is rolled on the winding bracket 304.

[0064] Multiple winding motors 301 have rollers 303 connected to their rotating ends. These rollers 303 engage in rolling friction with annular grooves on the sidewall of a rotating ring 302, thus limiting the rotation of the ring 302. A winding support 304 is connected to the end wall of the rotating ring 302, and the film roll is rolled onto the winding support 304. When the winding motors 301 are started, their rotating ends drive the rollers 303 to rotate. Due to the rolling friction between the rollers 303 and the annular grooves of the rotating ring 302, the rotating ring 302 is driven to rotate, which in turn drives the winding support 304 to rotate, thereby realizing the unwinding of the film roll and the winding of the film onto the core.

[0065] By cooperating with multiple winding motors 301 and rotating rings 302, stable and uniform winding of the film can be achieved. The limiting effect of multiple rollers 303 on the rotating rings 302 ensures the smooth rotation of the rotating rings 302, so that the film will not shake or deviate during the winding process. At the same time, this setting also prevents it from interfering with the core and the first track 10 and the second track 11.

[0066] In some embodiments, the pushing mechanism 20 includes a pushing motor 201 and a pushing clamp 202, the pushing clamp 202 having a clamping groove corresponding to the shape of the end cap 13.

[0067] The push motor 201 drives the push chuck 202 to move, so that the clamping groove can accurately lock the end cap 13 and push the end cap 13 to one end of the rock core, realizing the insertion of the end cap 13 into the rock core. In this embodiment, the clamping force between the clamping groove and the end cap 13 is less than the clamping force of the end cap 13 inserted into one end of the rock core. In this way, after the end cap 13 is connected to the rock core, it will not fall off as the push motor 201 retracts.

[0068] The inner wall of the end cap 13 is connected with a flared rubber ring, and the tail of the end cap 13 has a hexagonal structure.

[0069] With this setup, the rubber ring can more easily connect to the rock core after the film is wrapped around it, and it also provides better scalability for the ends of the film that have wrinkles.

[0070] It should be noted that the inner wall of the push chuck 202 is embedded with a rubber ring. The push chuck 202 has a box-shaped structure. With this setting, when the core is held, the push chuck 202 can slightly hold the core. The core can move within the push chuck 202, so that the movement direction of the push chuck 202 can be slightly deviated from the movement direction of the core, which can also be adapted to achieve the pushing of the core by the push chuck 202 at different angles.

[0071] In some embodiments, the lifting mechanism 40 includes a lifting seat 401, a lifting slide rail 402, a sliding platform 403, a telescopic motor 404, a telescopic gear 405, a telescopic toothed plate 406, a top platform 407, and a guide rod. The lifting slide rail 402 is connected to the lifting seat 401, the sliding platform 403 is slidably connected to the lifting slide rail 402, the telescopic motor 404 is connected to the sliding platform 403, the telescopic gear 405 is connected to the telescopic motor 404, the guide rod is vertically connected to the sliding platform 403, the top platform 407 is slidably connected to the guide rod, the telescopic toothed plate 406 is connected to the top platform 407, the sliding platform 403 has a telescopic groove corresponding to the position of the telescopic toothed plate 406, the telescopic gear 405 meshes with the telescopic toothed plate 406, and the sliding platform 403 moves along the core length direction on the lifting slide rail 402.

[0072] In this embodiment, the end of the first track 10 is provided with an opening, which is used for the top platform 407 to move.

[0073] During operation, the telescopic motor 404 drives the telescopic gear 405 to rotate, which, through meshing with the telescopic toothed plate 406, causes the top platform 407 to move up and down along the guide rod. Simultaneously, the sliding platform 403 can move along the lifting slide rail 402 following the length of the core to adjust the position of the top platform 407, ensuring it accurately lifts one end of the core. Furthermore, after the top platform 407 lifts the core, when the pushing mechanism 20 moves the end cap 13 to connect with the core, it is limited by the platform. By using an infrared sensor, it can detect different lengths of core and the position of the end film, and control the top platform 407 to move to the appropriate position, thus controlling the insertion length of the end cap 13 within the core. This achieves precise connection of the film and maintains a constant insertion length for cores of different lengths.

[0074] In some embodiments, the rotary moving mechanism 50 includes a rotary linear motor 501, a rotary push plate 502, a third track 12, and a rotary motor 503. The third track 12 is parallel to and corresponding to the second track 11. The rotary motor 503 is connected to the bottom of the third track 12. The rotary linear motor 501 is disposed on one side of the third track 12. The rotary push plate 502 is connected to the drive end of the rotary linear motor 501. The rotary linear motor 501 can extend and retract along the third track 12. When the core is completely inserted into the third track 12, the rotary motor 503 can drive the third track 12 to rotate 180 degrees.

[0075] During operation, the rotary linear motor 501 drives the rotary pusher plate 502 to move, which in turn moves the core. The rotary motor 503 drives the third track 12 to rotate. When the core enters the third track 12, the rotary motor 503 drives the third track 12 to rotate, achieving a 180-degree rotation of the core. Then, the rotary linear motor 501 drives the rotary pusher plate 502 to move, pushing the core out of the third track 12.

[0076] In some embodiments, an infrared laser sensor is also included, which is connected to the rotary pusher plate 502 and is used to detect the distance between the core and the rotary pusher plate 502 to determine whether the core has completely entered the third track 12.

[0077] An infrared laser sensor is connected to the rotary pusher plate 502. It detects the distance between the core and the rotary pusher plate 502 by emitting an infrared laser beam. When the core approaches the rotary pusher plate 502, the infrared laser beam is reflected back, and the sensor calculates the distance between the core and the rotary pusher plate 502 based on parameters such as reflection time. When the distance reaches a preset value, it is determined that the core has fully entered the third track 12, thus sending a signal to the control system to control subsequent rotation operations and other processes. The use of the infrared laser sensor enables precise detection of the core's position. It accurately determines whether the core has fully entered the third track 12, avoiding rotation operation errors caused by inaccurate core positioning. This improves the automation control accuracy and reliability of the equipment, reducing the possibility of manual intervention and misoperation. It helps ensure the smooth progress of the core packaging process, improving the efficiency and quality of the entire packaging work.

[0078] In some embodiments, a lifting motor 504 is also included. The bottom of the rotary motor 503 is connected to the lifting motor 504. When the core enters the third track 12, the height of the third track 12 is lower than the height of the second track 11. When one end of the core is about to leave the third track 12 and enter the second track 11, the height of the third track 12 is higher than the height of the second track 11. After one end of the core enters the second track 11, the height of the third track 12 returns to the initial height, which is lower than the height of the second track 11.

[0079] When the core enters the third track 12, the height of the third track 12 is lower than the height of the second track 11, which facilitates the entry of the inclined core into the third track 12. After one end of the core enters the second track 11, the height of the third track 12 returns to its initial height, which is lower than the height of the second track 11, so that the fulcrum formed by the third track 12 and the second track 11 can move the core out at an inclined angle, which facilitates the docking of the core with the pushing mechanism 20.

[0080] This application also provides a core encapsulation method, comprising the following steps:

[0081] The core is placed on the first track 10 and the second track 11, with one end overlapping the first track 10 and the other end overlapping the second track 11. The core is located near the winding start position of the film winding mechanism 30, which is located at the winding interval and adjacent to the second track 11.

[0082] Place one end of the plastic film tightly against the starting position of the core winding, start the film winding mechanism 30, and make it wind the plastic film to the outer wall of the core at a stable speed and force. At the same time, the pushing mechanism 20 starts the pushing action, which works in conjunction with the rotary moving mechanism 50. Both of them simultaneously hold and fix the core and assist the core to move towards the second track 11, from one end of the core to the other end. The core at both ends is not wound temporarily.

[0083] After the core is wrapped with film, the pushing mechanism 20 and the rotary moving mechanism 50 move the core toward the first track 10, so that it returns to the vicinity of the initial position and resets.

[0084] The lifting mechanism 40 is activated. The lifting mechanism 40 uses the end of the second track 11 as the rotation point to lift the end of the core near the first track 10 by a predetermined angle, so that sufficient space is formed between the core and the first track 10.

[0085] The pushing mechanism 20 inserts the pre-prepared end cap 13 through the gap formed after the lifting and connects it with the core. The end cap 13 is pressed against the end of the film after the core is wrapped with film.

[0086] The pushing mechanism 20 pushes the core to the rotary moving mechanism 50. The rotary moving mechanism 50 first rotates the core 180 degrees, then moves the core to dock with the pushing mechanism 20. Then, the rotary moving mechanism 50 cooperates with the pushing mechanism 20 to connect one end of the core to the first track 10 and the other end to the second track 11.

[0087] The end cap 13 at the other end is inserted into the core via the pushing mechanism 20, thus sealing both ends of the core.

[0088] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
