Description

Technical Field

[0001] This invention relates to the field of autoclave equipment technology, specifically a multi-fan autoclave. Background Technology

[0002] As the core equipment for curing and molding composite materials, the autoclave creates a high-temperature and high-pressure environment inside the sealed container to fully cure the composite material preform, which directly determines the mechanical properties, molding accuracy and quality stability of the finished product.

[0003] However, the existing equipment has a fixed tank length and poor versatility. When processing workpieces of different sizes, different models of autoclaves need to be matched, which not only increases the equipment procurement cost, but also results in insufficient internal heating uniformity due to the fixed position of the blower in the existing autoclave. Uneven heating will cause inconsistent resin curing degree, which in turn will lead to defects such as internal stress concentration, surface depression, and delamination in the workpiece, seriously affecting the mechanical properties and service life of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-fan autoclave to solve the problems mentioned in the background section.

The first tank body is fixedly installed on one of the first bearing seats, and the first tank body is located above the left end of the mounting box. The first tank body is provided with several interfaces and pressure gauges. The first tank body is provided with a sleeve wall, and there is a through-layer between the sleeve wall and the inner wall of the first tank body. The second tank body has the same structural diameter as the first tank body, and the inner wall is provided with a sleeve wall. The second tank body is fixedly installed on the other first bearing seat, and the second tank body is located below the first tank body. One end of a pair of second hydraulic cylinders is movably connected to the front and rear side walls of the mounting box, and the extension and retraction ends of the second hydraulic cylinders are respectively tilted to the left. The extension and retraction ends of the pair of second hydraulic cylinders are movably connected to one of the first flipping arms. The door is movably installed on the left end of the first tank body, and the door is closed by hydraulic drive.

[0007] Preferably, the end structure includes a pair of second slide rails, a second support seat, a third tank body, a docking seat, and a heating component; one end of each pair of second slide rails is symmetrically arranged in the mounting groove at the right end of the mounting box; the second support seat is fixedly arranged between the second slide rails and can move left and right through the second slide rails; the third tank body is the same as the first tank body and is fixedly arranged on the second support seat; the left end of the third tank body can be connected to the right end of the first tank body; one end of the docking seat is fixedly fitted onto the right end of the third tank body; and a rotating groove is provided on the circumference of the right side wall of the docking seat; the heating component is detachably installed on the right end of the third tank body.

[0008] Preferably, the heating assembly includes a motor, pulleys, a rotating base, a belt, four fans, a heating base, and a heater body;

[0009] The motor is fixedly mounted on the upper wall of the docking seat. The rotating seat is circular, and both its left and right side walls are provided with protruding rings. One end of the rotating seat is movably inserted into the transition groove of the docking seat through the ring on the left side wall. A sleeve groove is provided in the middle of the outer side wall of the rotating seat. Several through-hole ventilation openings are provided on the left side wall of the rotating seat, and the ventilation openings correspond to the interlayer between the sleeve wall and the first tank body. The two ends of the belt are respectively movably fitted onto the pulley and the sleeve groove of the rotating seat. One fan is fixedly inserted through the middle of the rotating seat, and the other three fans are respectively equidistantly arranged outside one of the fans.

[0013] Preferably, the first slide rail can drive the first tank body to move to the right and dock with the second tank body.

[0014] This invention proposes a multi-fan autoclave. Compared to traditional fixed autoclaves, this solution achieves embedded installation in the ground via a mounting box. The mounting box provides sufficient space, and a simple mechanical structure, utilizing the cooperation of a second and first hydraulic cylinder, moves the first and second autoclave bodies. This allows the second autoclave body to move from below the first autoclave body to its right side, thus achieving docking between the two bodies and extending the equipment. Alternatively, the second autoclave body can be folded under the first autoclave body for storage, accommodating workpieces of different lengths and improving the equipment's applicability. Furthermore, during heating, the design of the end structure allows for fan repositioning, improving airflow within the first autoclave body and promoting temperature uniformity. This achieves the following technical effects:

[0015] 1. The recessed mounting box enables embedded installation in the ground, ensuring the overall stability of the equipment installation. It also allows for the installation of simple mechanical structures using the reserved space inside the mounting box, eliminating the need for complex external transmission components. This significantly saves floor space, making the equipment layout more compact and suitable for workshops with limited space.

[0016] 2. Relying on the cooperation of the first hydraulic cylinder, the second hydraulic cylinder, the tilting arm, and the slide rail, the second tank body can be adjusted in both directions for "connection extension" or "folding and storage". When processing long workpieces, the second tank body can be flipped from under the first tank body to the right side and connected to extend the overall length of the equipment. When processing short workpieces, the second tank body can be folded back under the first tank body for storage. There is no need to replace different models of autoclaves. It can flexibly match the processing needs of workpieces of different lengths and improve the versatility of the equipment.

[0017] 3. The end structure drives the fan to reciprocate through the rotating seat, which can enhance the air flow efficiency in the first tank body, avoid the problem of "local airflow stagnation" in traditional autoclaves, promote uniform temperature distribution in the tank, reduce quality defects such as insufficient curing and stress concentration caused by uneven heating of composite materials and other workpieces, and improve the stability of finished product processing quality.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-8 This invention provides a technical solution: a multi-fan autoclave, including a mounting box 6, which is concave, and the upper right wall of the mounting box 6 is provided with mounting grooves 4. A docking structure 1 is provided inside the left end of the mounting box 6, and an end structure 3 is provided on the upper right end of the mounting box 6. The end structure 3 can be connected to the docking structure 1. The mounting box 6 is used to support and embed into the ground, and to support and reserve space for the docking structure 1. The docking structure 1 can adjust the length of the autoclave as needed. The end structure 3 is used to combine with the docking structure 1 to form a sealed environment and to transport high-temperature airflow in the docking structure 1.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment, the docking structure 1 further includes two pairs of first hydraulic cylinders 10, a pair of mounting seats 11, two pairs of first tilting arms 12, two pairs of second tilting arms 13, two pairs of docking plates 14, two pairs of first slide rails 15, a pair of first bearing seats 16, a first tank body 17, a second tank body 18, a pair of second hydraulic cylinders 19, and a door 20; one end of each of the two pairs of first hydraulic cylinders 10 is symmetrically arranged on the lower left wall of the mounting box 6, and the pair of mounting seats 11 are symmetrically arranged on the first hydraulic cylinders 10, and are mutually symmetrical; both pairs of first tilting arms 12 are V-shaped, and one end of each pair of first tilting arms 12 is symmetrically arranged on the mounting seats 11 in opposite directions, and the two ends of the first tilting arms 12 are relatively parallel; one end of each pair of second tilting arms 13 is fixed. The first tilting arm 12 is positioned on one opposite end of the second tilting arm 13, with the second tilting arm 13 pointing vertically downwards. Two pairs of docking plates 14 are movably positioned between the other ends of the second tilting arm 13 and the other ends of the first tilting arm 12, respectively. The docking plates 14 are symmetrically positioned on the upper and lower sides. The sliders of two pairs of first slide rails 15 are symmetrically positioned on the docking plates 14, with the first slide rails 15 positioned between the docking plates 14. A pair of first bearing seats 16 are respectively positioned between the first slide rails 15, and the pair of first bearing seats 16 are staggered vertically. The first tank body 17 is fixedly positioned on one of the first bearing seats 16, and the first tank body 17 is located above the left end of the mounting box 6. The first tank body 17 is provided with several interfaces and pressure gauges. Inside the first tank body 17... A sleeve wall 9 is provided, and the sleeve wall 9 and the inner wall of the first tank body 17 are connected by a through-layer. The second tank body 18 has the same structural diameter as the first tank body 17, and its inner wall is also provided with a sleeve wall 9. The second tank body 18 is fixedly mounted on another first support seat 16, and the second tank body 18 is located below the first tank body 17. One end of a pair of second hydraulic cylinders 19 is movably connected to the front and rear side walls of the mounting box 6, and the telescopic ends of the second hydraulic cylinders 19 are tilted to the left. The telescopic ends of the pair of second hydraulic cylinders 19 are movably connected to one of the first tilting arms 12. The door 20 is movably mounted on the left end of the first tank body 17, and the door 20 is closed by hydraulic drive. The height of the first tank body 17 and the second tank body 18 is adjusted by starting the first hydraulic cylinder 10. This allows the first tilting arm 12 and the second tilting arm 13 to be tilted by the second hydraulic cylinder 19, causing the first tank body 17 to be lifted and moved to the left. At the same time, the second tank body 18 moves a certain distance to the right from below the first tank body 17 and then rises upward, so that the second tank body 18 folds down to the right side of the first tank body 17 and the second tank body 18 and the first tank body 17 are on the same horizontal plane. Then, by starting the first slide rail 15, the second tank body 18 and the second tank body 18 move relative to each other to achieve docking. The docking structure 1 achieves flexible adjustment of the tank body through simple mechanical transmission, without the need for a complex electrical control system. Moreover, the installation and maintenance of each component are convenient, which can effectively adapt to the processing needs of workpieces of different lengths and improve the versatility and practicality of the multi-fan autoclave.

[0030] The docking structure 1 in this embodiment can realize two modes: "single tank body use" or "double tank body combination use" depending on the length of the workpiece. The specific working process of the double tank body combination use (i.e., the first tank body 17 and the second tank body 18 docking and extending) is as follows:

[0031] Height pre-adjustment stage: Activate two pairs of first hydraulic cylinders 10 to extend or shorten their telescopic ends synchronously, driving the mounting base 11, first tilting arm 12, second tilting arm 13 and first bearing base 16 to move up and down as a whole until the bottom of the first tank body 17 and the second tank body 18 are at a preset height from the ground, so as to avoid interference between the tank body and the mounting box 6 or the ground during the subsequent tilting process. After the adjustment is completed, the first hydraulic cylinder 10 maintains the current telescopic state and locks the height position.

[0032] Flipping and repositioning stage: A pair of second hydraulic cylinders 19 are activated to extend their telescopic ends synchronously, pushing the left first flipping arm 12, which is hinged to it, to rotate around the pin of the mounting base 11; Since the two pairs of first flipping arms 12 are designed in opposite directions, the rotation of the left first flipping arm 12 will drive the right first flipping arm 12 to rotate synchronously in the opposite direction through the linkage structure.

[0033] The first tilting arm 12 at the top drives the docking plate 14, the first slide rail 15 and the first bearing seat 16 at the top, so that the first tank body 17 is slightly lifted upward and moved to the left, leaving space on the right side for the second tank body 18 to be repositioned.

[0034] The first tilting arm 12 below drives the second tilting arm 13 to rotate synchronously. The second tilting arm 13, through the docking plate 14 below, the first slide rail 15 and the first bearing seat 16, drives the second tank body 18 to move to the right a preset distance from directly below the first tank body 17 (to avoid collision with the first tank body 17). Then, as the tilting arm continues to rotate, it is lifted upward until the axis of the second tank body 18 and the axis of the first tank body 17 are on the same horizontal plane. At this time, the second tank body 18 is located to the right of the first tank body 17, completing the tilting position. The second hydraulic cylinder 19 remains in the extension and retraction state, locking the tilting position.

[0035] Precision docking stage: Activate the two pairs of first slide rails 15, and control the sliders of the upper and lower slide rails to move synchronously along the guide rails towards the middle: the upper first slide rail 15 drives the first tank body 17 to move to the right, and the lower first slide rail 15 drives the second tank body 18 to move to the left; until the right flange of the first tank body 17 and the left flange of the second tank body 18 are completely fitted together, the two tank bodies are sealed and docked through the preset sealing element (such as sealing ring), forming a combined tank body structure of "first tank body 17 and second tank body 18", extending the effective processing length of the autoclave;

[0036] After docking is completed, the first slide rail 15 locks the slider position to ensure that the docking state of the two tanks is stable. At this time, the docking structure 1 can cooperate with the end structure 3 to form a complete ultra-long workpiece processing cavity.

[0037] If only medium-length workpieces need to be processed, there is no need to start the second tank body 18. The second tank body 18 can be kept in the storage state directly below the first tank body 17, and processing can be achieved by docking the first tank body 17 with the end structure 3, which simplifies the operation process.

[0038] like Figure 6 and Figure 7 As shown, as a preferred embodiment, the end structure 3 further includes a pair of second slide rails 31, a second support seat 32, a third tank body 33, a docking seat 34, and a heating component 35; one end of each pair of second slide rails 31 is symmetrically arranged in the mounting groove 4 at the right end of the mounting box 6; the second support seat 32 is fixedly arranged between the second slide rails 31, and the second support seat 32 can move left and right through the second slide rails 31; the third tank body 33 is the same as the first tank body 17, and the third tank body 33 is fixedly arranged in the mounting groove 4 at the right end of the mounting box 6. The second support seat 32 is mounted on the second support seat 32, and the left end of the third tank body 33 can be connected to the right end of the first tank body 17. One end of the docking seat 34 is fixedly fitted onto the right end of the third tank body 33, and a rotating groove is provided on the circumference of the right side wall of the docking seat 34. The heating component 35 can be detachably installed on the right end of the third tank body 33. The second slide rail 31 drives the second support seat 32 to move left and right, so that the third tank body 33 can be connected to the first tank body 17 or the second tank body 18. The docking seat 34 carries the heating component 35 and moves to connect.

[0039] More specifically, the end structure 3 is guided and connected to the docking structure 1 through the second slide rail 31, and the heating uniformity and maintenance convenience are ensured by the detachable heating component 35 and the sealed rotating seat 353. This effectively solves the defects of traditional autoclaves such as "fixed docking" and "difficult maintenance of heating component 35", and works with the docking structure 1 to realize the core functions of the multi-fan autoclave.

[0040] like Figure 6 and Figure 7As shown, as a preferred embodiment, the heating assembly 35 further includes a motor 351, a pulley 352, a rotating base 353, a belt 354, four fans 355, a heating base 356, and a heater body 357. The motor 351 is fixedly mounted on the upper wall of the docking seat 34, the pulley 352 is fixedly mounted on the drive end of the motor 351, the rotating base 353 is circular, and both the left and right side walls of the rotating base 353 are provided with protruding rings. One end of the rotating base 353 is movably inserted into the docking seat 34 through the ring on the left side wall. The adapter groove is located inside the rotating base 353, and a sleeve groove is provided in the middle of the outer wall of the rotating base 353. Several through ventilation holes 5 are provided on the left side wall of the rotating base 353, and the ventilation holes 5 correspond to the interlayer between the sleeve wall 9 and the first tank body 17. The two ends of the belt 354 are respectively movably fitted onto the pulley 352 and the sleeve groove of the rotating base 353. One fan 355 is fixedly inserted through the middle of the rotating base 353, and the other three fans 355 are equidistantly arranged on the outside of one of the fans 355. The heating base 356 has a cylindrical structure and is equipped with... The heating seat 356 has a similar rotating groove on its left side wall. The heating seat 356 is detachably mounted on the right side of the docking seat 34, and the heating seat 356 is movably fitted onto the right end of the rotating seat 353. The heating seat 356 and the docking seat 34 are connected by two pairs of connecting rods 7, and the connecting rods 7 are fixed to the docking seat 34 and the heating seat 356 by screw nuts 8. The connecting rods 7 are located on the outside of the rotating seat 353, and the heater body 357 is fixedly installed inside the heating seat 356. It is started by the motor 351, and moves with the pulley 352 and the leather... The belt 354 drives the rotating seat 353 to rotate on the docking seat 34. During the rotation, the rotating seat 353 remains in contact with the docking seat 34 and the heating seat 356, thereby adjusting the blowing position of the fan 355 and improving the uniformity of air pressure and heat in the first tank body 17. The air is drawn through the ventilation port 5 and is opposite to the interlayer of the sleeve wall 9 and the first tank body 17, and is fitted by the shielding of the rotating seat 353. When the fan 355 is started, the air is drawn through the ventilation port 5, heated by the heater body 357, and then blown into the fan 355 to form a circulation.

[0041] When the autoclave completes the docking and sealing of the tank body, the drive end of the motor 351 drives the pulley 352 to rotate synchronously. Since the two ends of the belt 354 are respectively movably fitted into the grooves of the pulley 352 and the rotating seat 353, the rotation of the pulley 352 is transmitted to the rotating seat 353 through the belt 354, causing the rotating seat 353 to reciprocate between the docking seat 34 and the heating seat 356 around its own axis (the reciprocating motion of the rotating seat 353 can be achieved by the motor 351 through forward and reverse control).

[0042] Heating and airflow generation are synchronized to start the heater body 357. After the heater body 357 is powered on, it generates high temperature and quickly heats the air inside the heating seat 356. At this time, four fans 355 rotate synchronously with the rotating seat 353 and start. The operation of the fans 355 generates negative pressure, which draws the high temperature air in the heating seat 356 from the right side. After being pressurized by the fans 355, it is delivered to the left side to form a directional high temperature airflow.

[0043] The high-temperature airflow conveyed by the directional airflow conveyor and the circulating fan 355 directly enters the interlayer formed by the inner wall sleeve 9 of the tank body through the vent 5 on the left side wall of the rotary seat 353. Since the vent 5 corresponds perfectly to the interlayer, and the rotary seat 353 always maintains the relative position of the vent 5 and the interlayer during rotation (only the air delivery angle of the fan 355 changes), the high-temperature airflow is evenly distributed throughout the entire tank body along the interlayer, heating the workpiece inside the tank. At the same time, the low-temperature airflow inside the tank flows back from the other end of the interlayer to the vent 5 of the rotary seat 353 under the negative pressure of the fan 355, is drawn in again by the fan 355 and heated by the heater body 357, forming a closed-loop airflow circulation of "heating, conveying, reflux and reheating", ensuring the temperature uniformity inside the tank.

[0044] Temperature uniformity is ensured by the reciprocating rotation of the rotary seat 353, which drives the four fans 355 to change their air delivery angles synchronously, avoiding the problem of "local airflow concentration" caused by traditional fixed air delivery. The equiangular distribution of the three outer fans 355 and the synergistic effect of the central fan 355 can cover the entire cross-section of the tank body interlayer, ensuring that there are no dead angles in the airflow. In addition, the through design of the vent 5 and the rotation shielding of the rotary seat 353 can adjust the rate of airflow into the interlayer, further optimizing the temperature distribution.

[0045] As a preferred option, the rotary seat 353 is started by the motor 351 and driven by the belt 354 to reciprocate between the docking seat 34 and the heating seat 356. This design improves the uniformity of the air supply and heating by the fan 355. The third tank body 33 can be connected to the right end of the second tank body 18. This design increases the length of the equipment.

[0046] As a preferred option, the second tank body 18 is further activated by the extension of the second hydraulic cylinder 19, which drives the first tilting arm 12 and the second tilting arm 13 to tilt, causing the second tank body 18 to be raised to the right side of the first tank body 17 and to be on the same horizontal plane as the first tank body 17. In the design of the tilting linkage process, the first slide rail 15 can drive the first tank body 17 to move to the right and dock with the second tank body 18 for docking.

[0047] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0048] The mounting box 6 is embedded in the ground. The concave structure provides support and movement space for the docking structure 1. The second slide rail 31 is pre-installed in the mounting groove 4 on the right end.

[0049] The first tank body 17 is fixed to the upper left end of the mounting box 6 by one of the first bearing seats 16, and the second tank body 18 is located directly below the first tank body 17 by the other first bearing seat 16 (staggered vertically); the first hydraulic cylinder 10 is in the retracted state, the second hydraulic cylinder 19 is in the retracted state, and the tilting arm assembly maintains the initial vertical posture; the door 20 is in the open state to facilitate the placement of the workpiece.

[0050] The third tank body 33 is fixed to the second slide rail 31 by the second bearing seat 32, and its initial position is located at the right end of the mounting box 6; the heater body 357 is supported by the heating seat 356, and the heating seat 356 is fixed to the right side of the docking seat 34 by the connecting rod 7 and the nut 8; the rotating seat 353 is movably set between the docking seat 34 and the heating seat 356, and the rotating seat 353, the fan 355, and the heater body 357 are in standby state;

[0051] The docking structure 1 can flexibly select between "single tank body docking" or "double tank body combination docking" according to the length of the workpiece. The specific process is as follows:

[0052] Case 1: Only the first tank body 17 and the third tank body 33 need to be docked, which is suitable for medium-length workpieces. There is no need to start the second tank body 18, and it can directly enter the docking stage of the end structure 3.

[0053] Scenario 2: The first tank body 17 and the second tank body 18 need to be combined to accommodate extra-long workpieces;

[0054] The two tank bodies are assembled through three steps: height adjustment, repositioning, and precise docking.

[0055] That is, start the two pairs of first hydraulic cylinders 10 to drive the mounting base 11, the tilting arm assembly and the first bearing base 16 to move up and down a certain distance, adjust the overall height of the first tank body 17 and the second tank body 18, and avoid interference with the mounting box 6 or the ground when tilting.

[0056] At the same time, a pair of second hydraulic cylinders 19 are activated, and their telescopic ends extend synchronously, pushing the V-shaped first tilting arm 12 connected to it to rotate around the mounting base 11. Since the two first tilting arms 12 are arranged symmetrically in opposite directions, the first tilting arm 12 drives the first tank body 17 to lift slightly upward and move to the left, leaving space for docking on the right side.

[0057] At the same time, the first tilting arm 12 drives the second tilting arm 13 to tilt synchronously. During the tilting, the lower docking plate 14 and the second tank body 18 move synchronously: the second tank body 18 first moves to the right a preset distance from directly below the first tank body 17 to avoid collision, and then continues to rotate with the tilting arm to lift upward until the axis of the second tank body 18 and the axis of the first tank body 17 are on the same horizontal plane. At this time, the second tank body 18 is located to the right of the first tank body 17.

[0058] Finally, the two pairs of first slide rails 15 are activated, and their sliders synchronously drive the first bearing seat 16 along the guide rails to move the first tank body 17 to the right until the two tank bodies are completely fitted together to form a combination of "first tank body 17 and second tank body 18", thus completing the length extension.

[0059] After the tank length adjustment is completed, the second slide rail 31 of the installation slot 4 is activated to achieve a sealed connection with the docking structure 1, thus constructing a complete processing tank cavity: the pair of second slide rails 31 of the end structure 3 are activated, which drives the second bearing seat 32 and the third tank body 33 to move to the left along the tank body axis. At this time, the third tank body 33 can fit with the right end of the first tank body 17 or fit with the right end of the second tank body 18 for docking and combination.

[0060] The workpiece can be put into the first tank body 17, and the hydraulically activated door 20 at the left end of the first tank body 17 is closed. The door 20 is pressed and sealed by hydraulic power, thus forming a "fully sealed pressure-resistant tank cavity".

[0061] During heating operation, high-temperature airflow circulates:

[0062] After the sealed tank cavity is constructed, the heating component 35 is activated to achieve uniform high temperature distribution inside the tank; the motor 351 of the heating component 35 located on the docking seat 34 is activated, the drive end of the motor 351 drives the pulley 352 to rotate, and the power is transmitted to the rotating seat 353 through the belt 354. The rotating seat 353 is rotatably fitted into the rotating groove of the docking seat 34 and the heating seat 356 through the protruding rings on the left and right sides.

[0063] The heater body 357 inside the heating seat 356 is activated simultaneously. The heater body 357 generates high temperature when powered on, which heats the air in the cavity inside the heating seat 356. The four fans 355 on the rotating seat 353 (one in the center and three equidistantly distributed on the outside) generate suction force when the fans 355 operate, drawing the high temperature air from the heating seat 356. The high temperature air is transported by the fans 355 to the sleeve wall 9 of the third tank body 33, the second tank body 18 and the first tank body 17. The sleeve wall 9 and the interlayer of the first tank body 17 are opposite to the vent 5, so the airflow can be drawn from the left end of the first tank body 17 into the interlayer and flow into the heating seat 356 to form a circulation.

[0064] Motor 351 drives rotary table 353 to reciprocate (achieved by forward and reverse rotation of motor 351), which in turn drives four fans 355 to adjust their blowing positions to avoid local airflow stagnation in the jacket, ensuring that the temperature deviation in each area of ​​the tank is controlled within the minimum range, and guaranteeing the processing quality of the workpiece.

[0065] When the equipment is in use, the internal vacuuming, pressurization, temperature measurement, and pressure measurement can all be achieved by setting up existing equipment and connecting the corresponding pipelines using existing technology.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
