Description

Technical Field

[0001] The present invention relates to the technical field of casing processing and measurement, and in particular to a casing waist-shaped tube angle position detection device and a detection method thereof. Background Art

[0002] like Figure 1 and Figure 2 As described, three bleed air ducts with waist-shaped cross-sections are welded to the inner wall of the engine combustion chamber casing along the circumference. In order to meet the needs of assembling other components of the casing, the symmetrical center axis of the waist-shaped ducts has an angle requirement with the reference axis of the casing. Specifically, the casing includes a support seat and a positioning ring fixedly connected to the lower end face of the support seat. The positioning ring and the support seat are coaxially arranged and perpendicular to each other. A reference hole is opened on the support seat, wherein the line connecting the reference hole and the center axis of the casing is the angular reference line. The first reference line is located on the counterclockwise side of the angular reference line and is at an angle of 9°30′ to the angular reference line. The second reference line is mutually perpendicular to the first reference line. The first waist-shaped tube is perpendicular to the base hole, and the first waist-shaped tube, the second waist-shaped tube and the third waist-shaped tube are arranged circumferentially on the inner side of the casing along the center axis of the casing. The angle between the symmetry center axis of the first waist-shaped tube and the first reference line is γ±10′, the angle between the symmetry center axis of the second waist-shaped tube and the second reference line is β±10′, and the angle between the symmetry center axis of the third waist-shaped tube and the first reference line is α±10′. After the waist-shaped tubes are welded, the above angles need to be tested to ensure that the angle between the symmetry center axis of the waist-shaped tube and the reference axis of the casing meets the design requirements. However, due to the waist-shaped cross-section of the pipe, it is difficult to find the symmetry center of the waist-shaped tube when directly testing the angle. It is necessary to calculate and measure the waist-shaped tube using coordinate measurement after setting the coordinate system in order to calibrate the symmetry center of the waist-shaped tube. Such measurement efficiency is low and it is difficult to meet the production requirements of the casing. Summary of the Invention

[0017] The present invention has the following beneficial effects:

[0018] In the detection device for the angular position of the waist-shaped tube of the receiver of the present invention, the base is provided for positioning the receiver so that the reference axis used for arranging the waist-shaped tube on the receiver overlaps with the reference axis when the detection member is arranged relative to the base, that is, the angular reference line of the receiver overlaps with the positioning reference axis, and the arrangement angle of the detection member and the positioning reference axis is consistent with the arrangement angle of the waist-shaped tube relative to the angular reference line when the waist-shaped tube is designed to be arranged, so that the detection member can be used as a detection standard for the angular position of the waist-shaped tube on the receiver. Among them, the detection device for the angular position of the waist-shaped tube of the receiver includes a base, a support plate, a pillar connecting the base and the support plate, and a detection mechanism arranged on the support plate. The support ring on the base is used to limit the receiver, and the angular pin arranged on the support ring is used to adapt to the reference hole so that the angular reference line of the receiver overlaps with the positioning reference axis of the base. At the same time, the upper end face of the support ring abuts against the lower end face of the support seat to axially position the receiver relative to the base. The pillar is connected to the base to support the support plate and make the upper end face of the support plate close to the upper end of the waist-shaped tube, so that the detection mechanism arranged on the support plate can detect the angular position of the waist-shaped tube. The detection mechanism includes a monitoring pin and a support pin arranged on the support plate corresponding to the design position of the waist-shaped tube relative to the receiver. The detection part is on the plate, wherein the waist-shaped part in the positioning pin is used to fit and abut against the inner wall of the waist-shaped tube so that the positioning pin is fixed to the tube mouth of the waist-shaped tube, and the central axis of the positioning column overlaps with the symmetry center of the waist-shaped part, so that the central axis of the positioning column overlaps with the symmetry center of the waist-shaped tube, so that the positioning column replaces the symmetry center of the waist-shaped tube for easy intuitive detection. The detection part includes a positioning support arranged on the support plate and a gauge slidably connected to the positioning support along the radial direction of the support plate. Specifically, a U-shaped groove adapted to the positioning column is opened on the gauge, and the sliding gauge moves the gauge toward the positioning column. If the positioning column can be embedded in the U-shaped groove, it means that the angular position of the waist-shaped tube where the positioning column is installed is qualified. Through the above device, after the receiver to be inspected is positioned by the support ring on the base, it is ensured that the angular reference line of the receiver overlaps with the positioning reference axis of the base. At this time, it is only necessary to install the positioning pin on the waist-shaped tube, and the angular position of the waist-shaped tube can be judged by the sliding gauge. Specifically, the gauge moves toward the positioning column. If the positioning column can be embedded in the U-shaped groove, the angular position of the waist-shaped tube on the receiver is qualified; if the positioning column cannot be embedded in the U-shaped groove, the angular position of the waist-shaped tube on the receiver is unqualified, and the waist-shaped tube is adjusted so that the positioning column can be embedded in the U-shaped groove. Through the above device, the angular relationship between the symmetry center of the waist-shaped tube and the angular reference line, which is difficult to visually judge, is converted and the U-shaped groove can be visually judged after the moving gauge is moved to determine whether the angular position of the waist-shaped tube on the receiver is qualified, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube on the receiver is qualified, thereby improving production efficiency.

[0019] During the specific implementation, the reference hole on the receiver is first matched with the angle pin so that the upper end face of the support ring abuts against the lower end face of the support seat, thereby positioning the receiver relative to the base, and then the detection pin is installed with the end of the waist-shaped tube away from the support seat so that the waist-shaped part extends into the waist-shaped tube and the positioning column is located outside the waist-shaped tube. Finally, the sliding gauge is used to move the gauge toward the positioning column. If the positioning column can be embedded in the U-shaped groove, the angular position of the waist-shaped tube on the receiver is qualified; if the positioning column cannot be embedded in the U-shaped groove, the angular position of the waist-shaped tube on the receiver is unqualified, and the position of the waist-shaped tube is adjusted so that the positioning column can be embedded in the U-shaped groove. In summary, the above-mentioned device converts the original method of detecting the angular position of the waist-shaped tube, which requires calculating and measuring the position of the symmetrical center axis of the waist-shaped tube, and then judging whether the angular position of the waist-shaped tube is qualified by measuring the angular relationship between the symmetrical center axis of the waist-shaped tube and the angular reference line, into an intuitive judgment of whether the U-shaped groove can cooperate with the positioning column, which reduces the tediousness of the detection, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube on the receiver is qualified, and thus improving production efficiency.

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0037] like Figures 1 to 4As shown, a detection device for the angular position of a waist-shaped tube 104 of a receiver 100 of this embodiment is used to detect the angular position of the waist-shaped tube 104. The receiver 100 includes a support base 101 and a positioning ring 102 fixedly connected to the lower end surface of the support base 101. The positioning ring 102 is coaxially arranged with the support base 101 and perpendicular to each other. The support base 101 is provided with a reference hole 103 for positioning. The receiver 100 includes a base 200, a support 300 and a detection mechanism. The base 200 is provided with a support hole 103 connected to the base 200. 200 coaxially arranged support ring 201, the support ring 201 is provided with an angular pin 202 for adapting to the reference hole 103, the center axis of the angular pin 202 and the line connecting the center axis of the base 200 is the positioning reference axis, the upper end surface of the support ring 201 is used to abut against the lower end surface of the support seat 101 to axially position the casing 100, the angular pin 202 is used to insert into the reference hole 103 to align the angular reference line of the casing 100 with the positioning of the base 200 The reference axis overlaps; one end of the pillar 300 is fixedly connected to the base 200, and the other end of the pillar 300 is provided with a support plate 600 coaxially arranged with the bottom plate; the detection mechanism includes a detection pin 400 and a detection member 500 arranged on the support plate 600 corresponding to the design position of the waist-shaped tube 104 relative to the casing 100, the detection member 500 includes a positioning support 501 provided on the support plate 600 and a sliding member 501 along the radial direction of the support. The dynamically connected gauge 504, the detection pin 400 includes a waist-shaped portion 401 for adapting to the inner wall of the waist-shaped tube 104 and a positioning column 402 fixed at one end of the waist-shaped portion 401, the central axis of the positioning column 402 overlaps with the symmetry center of the waist-shaped portion 401, and the gauge 504 is provided with a U-shaped groove 506 adapted to the positioning column 402, the U-shaped groove 506 is arranged along the radial direction of the support plate 600, and the opening of the U-shaped groove 506 is facing the waist-shaped tube 104.

[0038] In this embodiment, the number of waist-shaped tubes 104 of the receiver 100 that need to be measured is three, and the waist-shaped tube 104 close to the reference hole 103 is set as the first waist-shaped tube 104. The first waist-shaped tube 104, the second waist-shaped tube 104 and the third waist-shaped tube 104 are arranged circumferentially on the inner side of the receiver 100 along the central axis of the receiver 100 in sequence. The line connecting the reference hole 103 and the central axis of the receiver 100 is the angular reference line. The first reference line is located on the counterclockwise side of the angular reference line and forms an angle of 9°30′ with the angular reference line. The second reference line is perpendicular to the first reference line. At this time, the angle between the center axis of symmetry of the first waist-shaped tube 104 and the first reference line is γ±10′, the angle between the center axis of symmetry of the second waist-shaped tube 104 and the second reference line is β±10′, and the angle between the center axis of symmetry of the third waist-shaped tube 104 and the first reference line is α±10′. Correspondingly, in the detection device for the angular position of the waist-shaped tube 104 of the receiver 100, there are also three detection members 500 provided on the support plate 600, and the detection member 500 close to the angle pin 202 is set as the first detection member 500. The first detection member 500, the second detection member 500 and the third detection member 500 are arranged circumferentially on the support plate 600 along the central axis of the base 200 in sequence. At this time, the line connecting the angle pin 202 and the central axis of the base 200 is set as the positioning reference axis for aligning the detection members 500. The first positioning line for positioning at the angular position is located on the counterclockwise side of the positioning reference axis and forms an angle of 9°30′ with the positioning reference axis. The second positioning line is perpendicular to the first positioning line. At this time, the angle between the central symmetry axis of the U-shaped groove 506 on the first detection member 500 and the first positioning line is γ, the angle between the central symmetry axis of the U-shaped groove 506 on the second detection member 500 and the second positioning line is β, and the angle between the central symmetry axis of the U-shaped groove 506 on the third detection member 500 and the first positioning line is α. In order to take into account the influence of the tolerance of ±10′, the angle tolerance needs to be converted into the width of the U-shaped groove 506. If the diameter of the positioning column 402 is A, the width of the U-shaped groove 506 needs to be converted into the width tolerance ±X according to the angle tolerance of ±10′. At this time, the width of the U-shaped groove 506 is A±X. Specifically, according to the circumferential diameter (φ282.1mm) of the center of the waist-shaped tube 104 on the receiver 100, the angle tolerance of ±10′ is used to draw or calculate, and it can be concluded that the position tolerance of the center of the waist-shaped tube 104 is φ0.82mm. Considering the tolerance of the hole of the waist-shaped tube 104 and the processing capability of the parts, the position tolerance is taken as ±0.7mm, that is, the width of the U-shaped groove 506 is A±0.7mm.

[0039] Specifically, the base 200 is provided for positioning the receiver 100 so that the reference axis for arranging the waist-shaped tube 104 on the receiver 100 overlaps with the reference axis when the detection member 500 is arranged relative to the base 200, that is, the angular reference line of the receiver 100 overlaps with the positioning reference axis, and the arrangement angle of the detection member 500 and the positioning reference axis is consistent with the arrangement angle of the waist-shaped tube 104 relative to the angular reference line when the waist-shaped tube 104 is designed to be arranged, so that the detection member 500 can be used as a detection standard for the angular position of the waist-shaped tube 104 on the receiver 100. Among them, the detection device for the angular position of the waist-shaped tube 104 of the casing 100 includes a base 200, a support plate 600, a pillar 300 connecting the base 200 and the support plate 600, and a detection mechanism arranged on the support plate 600. The support ring 201 on the base 200 is used to limit the casing 100. The angular pin 202 arranged on the support ring 201 is used to adapt to the reference hole 103 so that the angular reference line of the casing 100 overlaps with the positioning reference axis of the base 200. At the same time, the upper end surface of the support ring 201 abuts against the lower end surface of the support seat 101 so that the casing 100 is axially positioned relative to the base 200. The pillar 300 is connected to the base 200 to support the support plate 600 and make the upper end surface of the support plate 600 close to the upper end of the waist-shaped tube 104, so that the detection mechanism arranged on the support plate 600 can detect the angular position of the waist-shaped tube 104. The detection mechanism includes a monitoring pin and a positioning pin arranged corresponding to the design position of the waist-shaped tube 104 relative to the casing 100. The detection member 500 is provided on the support plate 600, wherein the waist-shaped portion 401 of the positioning pin is used to abut against the inner wall of the waist-shaped tube 104, so that the positioning pin is fixed to the tube mouth of the waist-shaped tube 104, and the central axis of the positioning column 402 overlaps with the symmetry center of the waist-shaped portion 401, thereby making the central axis of the positioning column 402 overlap with the symmetry center of the waist-shaped tube 104, so that the positioning column 402 replaces the symmetry center of the waist-shaped tube 104 for easy visual detection. It includes a positioning support 501 set on the support plate 600 and a gauge 504 slidably connected to the positioning support 501 along the radial direction of the support plate 600. Specifically, a U-shaped groove 506 adapted to the positioning column 402 is opened on the gauge 504. The sliding gauge 504 moves the gauge 504 toward the positioning column 402. If the positioning column 402 can be embedded in the U-shaped groove 506, it means that the angular position of the waist-shaped tube 104 installed by the positioning column 402 is qualified.By means of the above-mentioned device, the casing 100 to be inspected is positioned by the support ring 201 on the base 200, ensuring that the angular reference line of the casing 100 overlaps with the positioning reference axis of the base 200. At this time, it is only necessary to install the positioning pin on the waist-shaped tube 104, and the angular position of the waist-shaped tube 104 can be judged by the sliding gauge 504. Specifically, the gauge 504 moves toward the positioning column 402. If the positioning column 402 can be embedded in the U-shaped groove 506, the angular position of the waist-shaped tube 104 on the casing 100 is qualified; if the positioning column 402 cannot be embedded in the U-shaped groove 506, the angular position of the waist-shaped tube 104 on the casing 100 is unqualified, and the position of the waist-shaped tube 104 is adjusted so that the positioning column 402 can be embedded in the U-shaped groove 506. Through the above-mentioned device, the angular relationship between the symmetry center of the waist-shaped tube 104 and the angular reference line, which is difficult to visually judge, is converted and the U-shaped groove 506 after the moving gauge 504 can be visually judged to see whether it can cooperate with the positioning column 402, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube 104 on the receiver 100 is qualified, thereby improving production efficiency.

[0040] In a specific implementation, the reference hole 103 on the receiver 100 is first matched with the angle pin 202 so that the upper end surface of the support ring 201 abuts against the lower end surface of the support seat 101, thereby positioning the receiver 100 relative to the base 200. Then, the detection pin 400 is installed on the end of the waist-shaped tube 104 away from the support seat 101, so that the waist-shaped portion 401 extends into the waist-shaped tube 104 and the positioning column 402 is located outside the waist-shaped tube 104. Finally, The sliding gauge 504 is moved toward the positioning post 402. If the positioning post 402 can be embedded in the U-shaped groove 506, the angular position of the waist-shaped tube 104 on the receiver 100 is qualified; if the positioning post 402 cannot be embedded in the U-shaped groove 506, the angular position of the waist-shaped tube 104 on the receiver 100 is unqualified, and the position of the waist-shaped tube 104 is adjusted so that the positioning post 402 can be embedded in the U-shaped groove 506. In summary, the above-mentioned device converts the original method of detecting the angular position of the waist-shaped tube 104, which requires calculating and measuring the position of the symmetrical center axis of the waist-shaped tube 104, and then judging whether the angular position of the waist-shaped tube 104 is qualified by measuring the angular relationship between the symmetrical center axis of the waist-shaped tube 104 and the angular reference line, into an intuitive judgment of whether the U-shaped groove 506 can cooperate with the positioning column 402, which reduces the complexity of the detection, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube 104 on the receiver 100 is qualified, and further improving production efficiency.

[0041] Reference Figure 5The positioning support 501 is provided with a sliding groove 502 extending radially along the support plate 600. The gauge 504 is positioned within and slides along the sliding groove 502. In this embodiment, the sliding groove 502 provided on the positioning support 501 is used to define the movement trajectory of the gauge 504, allowing the gauge 504 to slide stably along the radial direction of the support plate 600, thereby ensuring that the central axis of symmetry of the U-shaped groove 506 does not deviate, thereby ensuring the accuracy of the test results.

[0042] Furthermore, the positioning support 501 is provided with a limiting groove 503 that communicates with the sliding groove 502. The limiting groove 503 is located on the side wall of the sliding groove 502, and the gauge 504 is provided with a limiting block 505 that matches the limiting groove 503. In this embodiment, the provision of the limiting groove 503 further limits the movement direction of the gauge 504, making it difficult for the gauge 504 to move circumferentially and allowing it to slide stably along the radial direction of the support plate 600. This also facilitates the assembly of the gauge 504. During assembly, it is only necessary to align the limiting block 505 with the limiting groove 503 and then push the gauge 504 into the limiting groove 503. This prevents the gauge 504 from detaching from the positioning support 501 in the axial direction. In specific settings, the limiting groove 503 can be opened only on one side wall of the sliding groove 502, or can be correspondingly set on both side walls of the sliding groove 502 to form a T-shaped groove, and the limiting block 505 is set corresponding to the limiting groove 503.

[0043] Reference Figure 6 The gauge 504 is provided with a strip-shaped hole 507 arranged along the radial direction of the support plate 600. A limit screw 509 is provided on the gauge 504. The limit screw 509 passes through the strip-shaped hole 507 and is fixedly connected to the support, thereby connecting the gauge 504 to the positioning support 501. In this embodiment, the length of the strip-shaped hole 507 determines the distance that the gauge 504 can move along the radial direction of the support plate 600. At the same time, the limit screw 509 passes through the strip-shaped hole 507 and is fixed to the positioning support 501, thereby connecting the gauge 504 to the positioning support 501, thereby preventing the gauge 504 from detaching from the positioning support 501 during movement.

[0044] Furthermore, the positioning support 501 is provided with positioning holes 508 correspondingly arranged on both sides of the sliding groove 502, and the symmetric center axes of the two positioning holes 508 are parallel to the symmetric center axis of the U-shaped groove 506 along the radial direction of the support plate 600, and the positioning support 501 is threadedly connected to the support plate 600 by fixing screws passing through the positioning holes 508.

[0045] Furthermore, the support plate 600 is provided with a plurality of circumferentially arranged positioning threaded holes 601 for mounting the positioning support 501. In this embodiment, the support plate 600 is provided with a plurality of circumferentially arranged positioning threaded holes 601, and the arrangement of the positioning threaded holes 601 can adapt to various waist-shaped tube 104 layouts. To enhance the detection versatility of the device, the positioning support 501 is removably connected to the support plate 600 via fixing screws. When measuring waist-shaped tubes 104 at different angular positions, the detection member 500 can be disassembled and installed in the appropriate positioning threaded hole 601 to accommodate the corresponding waist-shaped tube 104 layout.

[0046] Furthermore, the number of the pillars 300 is multiple, and the multiple pillars 300 are evenly distributed circumferentially around the central axis of the base 200. In this embodiment, the number of the pillars 300 is three, and the three pillars 300 are evenly distributed circumferentially between the base 200 and the support plate 600 around the central axis of the base 200. When arranged in this manner, the support plate 600 has strong installation stability. In other embodiments, the pillars 300 can be configured as a height-adjustable structure. Specifically, the pillars 300 include a lower pillar 300 connected to the base 200 and an upper pillar 300 connected to the support plate 600. The upper and lower pillars 300 are each provided with a plurality of through holes arranged along the height direction. When inspecting casings 100 of different heights, the upper pillar 300 can be adjusted to the appropriate height, and then bolts are passed through the through holes to secure the upper and lower pillars 300.

[0047] Furthermore, the inner sidewall of the support ring 201 is configured to abut against the outer sidewall of the positioning ring 102 to radially position the casing 100 relative to the base 200. In this embodiment, the inner sidewall of the support ring 201 abuts against the outer sidewall of the positioning ring 102 to achieve radial positioning of the casing 100 relative to the base 200 during installation, thereby preventing radial movement of the casing 100 from affecting the test results.

[0048] Furthermore, a handle 700 for conveniently carrying the detection device for the angle position of the waist-shaped tube of the receiver is fixedly connected to the base 200. The setting of the handle 700 facilitates the transportation and transfer of the detection device.

[0049] According to another aspect of the present invention, a method for detecting the angular position of the waist-shaped tube 104 of the receiver 100 is provided. The method uses the above-described detection device for the angular position of the waist-shaped tube to detect whether the angular position of the waist-shaped tube 104 on the receiver 100 is qualified, and includes the following steps:

[0050] S100, the reference hole 103 on the casing 100 is engaged with the angle pin 202, so that the upper end surface of the support ring 201 abuts against the lower end surface of the support seat 101, thereby positioning the casing 100 relative to the base 200;

[0051] In step S100, to facilitate the mating of the angle pin 202 and the reference hole 103, a guiding bevel is provided on the angle pin 202. The line connecting the reference hole 103 and the central axis of the receiver 100 serves as the angular reference line, while the line connecting the central axis of the angle pin 202 and the central axis of the base 200 serves as the positioning reference axis. The reference hole 103 and the angle pin 202 mate to ensure that the angular reference line and the positioning reference axis overlap. This means that the reference axis used for positioning the waist-shaped tube 104 on the receiver 100 overlaps with the reference axis used for positioning the detection member 500 relative to the base 200. The angle at which the detection member 500 is positioned relative to the positioning reference axis coincides with the angle at which the waist-shaped tube 104 is positioned relative to the angular reference line during the design of the waist-shaped tube 104. This allows the detection member 500 to serve as a standard for detecting the angular position of the waist-shaped tube 104 on the receiver 100.

[0052] S200, installing the detection pin 400 and the end of the waist-shaped tube 104 away from the support base 101, so that the waist-shaped portion 401 extends into the waist-shaped tube 104 and the positioning column 402 is located outside the waist-shaped tube 104;

[0053] For step S200, the waist-shaped portion 401 in the positioning pin is used to fit and abut against the inner wall of the waist-shaped tube 104 so that the positioning pin is fixed at the tube mouth of the waist-shaped tube 104, and the central axis of the positioning column 402 overlaps with the symmetry center of the waist-shaped portion 401, thereby making the central axis of the positioning column 402 overlap with the symmetry center of the waist-shaped tube 104, so that the positioning column 402 replaces the symmetry center of the waist-shaped tube 104 for easy intuitive detection.

[0054] S300, by sliding the gauge 504, so that the gauge 504 moves toward the positioning column 402, if the positioning column 402 can be embedded in the U-shaped groove 506, the angle position of the waist-shaped tube 104 arranged on the receiver 100 is qualified; if the positioning column 402 cannot be embedded in the U-shaped groove 506, the angle position of the waist-shaped tube 104 arranged on the receiver 100 is unqualified, and the position of the waist-shaped tube 104 is adjusted so that the positioning column 402 can be embedded in the U-shaped groove 506.

[0055] With respect to step S300, the angular relationship between the symmetry center of the waist-shaped tube 104 and the angular reference line, which is difficult to visually determine, is converted and the U-shaped groove 506 after the moving gauge 504 can be visually determined to cooperate with the positioning post 402, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube 104 on the receiver 100 is qualified.

[0056] In summary, the above-mentioned device converts the original method of detecting the angular position of the waist-shaped tube 104, which requires calculating and measuring the position of the symmetrical center axis of the waist-shaped tube 104, and then judging whether the angular position of the waist-shaped tube 104 is qualified by measuring the angular relationship between the symmetrical center axis of the waist-shaped tube 104 and the angular reference line, into an intuitive judgment of whether the U-shaped groove 506 can cooperate with the positioning column 402, which reduces the complexity of the detection, thereby improving the efficiency of detecting whether the angular position of the waist-shaped tube 104 on the receiver 100 is qualified, and further improving production efficiency.

[0057] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
