[0038] To better understand the technical solutions and beneficial effects of the present disclosure, the following further describes the present disclosure in detail with specific embodiments:

[0039] As Figures 1 to 4 shown, an airtightness detection device 10 for a filter element of an automotive ventilation seat in an embodiment includes a frame 100, a conveying mechanism 200, a feeding mechanism 300, a detection mechanism 400, and a discharging mechanism 500. The conveying mechanism 200 includes a conveying frame 210 and a first driving member 220. The first driving member 220 is installed on the frame 100, and the power output end of the first driving member 220 is connected to the conveying frame 210 to move the conveying frame 210. A clamp 230 is provided on the conveying frame 210, and the clamp 230 is used to accommodate a plurality of filter elements. Specifically, a plurality of grooves are formed on the clamp 230, and a plurality of filter elements are correspondingly located in the grooves.

[0040] The feeding mechanism 300 is installed on the frame 100. The feeding mechanism 300 is used to convey the filter element to the fixture 230 of the conveying rack 210, so as to embed a plurality of filter elements into the grooves correspondingly. Further, the detection mechanism 400 includes a pressing detection component 410 and a blowing component 420. Both the pressing detection component 410 and the blowing component 420 are installed on the frame 100. The pressing detection component 410 and the blowing component 420 are arranged opposite to each other. The pressing detection component 410 is used to move and abut against the surface of the filter element on the fixture 230. The blowing component 420 is used to move and abut against the bottom surface of the filter element on the fixture 230 and blow air to the filter element, so that the pressing detection component 410 detects the air pressure passing through the filter element. Further, the discharging mechanism 500 is installed on the frame 100. The discharging mechanism 500 is used to put the filter element on the fixture 230 into the collection box.

[0041] In this embodiment, the feeding mechanism 300, the detection mechanism 400 and the discharging mechanism 500 are arranged adjacent to each other. The first driving member 220 drives the conveying rack 210 to pass through the feeding mechanism 300, the detection mechanism 400 and the discharging mechanism 500 in sequence. When the first driving member 220 drives the conveying rack 210 to move to the feeding mechanism 300, the feeding mechanism 300 embeds a plurality of filter elements into the fixtures 230 on the conveying rack 210 one by one. Then the conveying rack 210 moves to the detection mechanism 400. At this time, the pressing detection component 410 moves and abuts against the surface of the filter element, and the detection end of the pressing detection component 410 is located inside the filter element. The blowing component 420 moves and abuts against the bottom surface of the filter element, that is, the pressing detection component 410 and the blowing component 420 clamp the filter element in the middle, and the filter element is surrounded by the fixture 230. The acting end of the blowing component 420 extends into the filter element and blows air to the filter element. The pressing detection component 410 feeds back the detected data to the control end to judge whether the filter element is qualified. Finally, the first driving member 220 moves the conveying rack 210 to the discharging mechanism 500, and the discharging mechanism 500 puts the qualified and unqualified filter elements into the corresponding collection boxes according to the feedback data. Further, the first driving member 220 is a cylinder or a motor.

[0042] The above-mentioned airtightness detection device 10 for the filter element of the automotive ventilation seat. The first driving member 220 drives the conveying rack 210 to sequentially pass through the feeding mechanism 300, the detection mechanism 400 and the discharging mechanism 500. The feeding mechanism 300 conveys the filter element to the fixture 230 of the conveying rack 210. After the pressing detection component 410 moves and abuts against the surface of the filter element on the fixture 230, the air blowing component 420 moves and abuts against the bottom surface of the filter element on the fixture 230, that is, the pressing detection component 410, the fixture 230 and the air blowing component 420 completely wrap the filter element. After the air blowing component 420 blows air into the filter element, the airtightness of the filter element is detected through the pressing detection component 410. In this way, the accuracy of simultaneously detecting multiple filter elements on the fixture 230 is improved. After the detection is completed, the filter elements are put into the corresponding collection boxes through the discharging mechanism 500. In this way, through the whole-process automated operation, the steps of manual operation are reduced and the production efficiency is improved.

[0043] As Figure 4 shown, in one embodiment, the air blowing component 420 includes an air pump (not shown in the figure), a first bracket 421, a second driving member 422 and an air blowing cylinder 423. The air pump is installed on the frame 100. The air blowing cylinder 423 is communicated with the air pump through a pipeline. The first bracket 421 is installed on the frame 100. The second driving member 422 is connected to the first bracket 421. The power output end of the second driving member 422 is connected to the air blowing cylinder 423 to drive the air blowing cylinder 423 to approach or move away from the filter element in the fixture 230. In this embodiment, the air pump is communicated with the air blowing cylinder 423 through a pipeline. The second driving member 422 drives the air blowing cylinder 423 to move to approach or move away from the filter element on the fixture 230. When the conveying rack 210 conveys the filter element to the preset position, the second driving member 422 drives the air blowing cylinder 423 to move in the vertical direction, so that the air blowing cylinder 423 is in close contact with the bottom surface of the filter element, and at the same time, the air outlet of the air blowing cylinder 423 is located inside the filter element to blow air into the filter element. Further, the second driving member 422 is a motor or a cylinder.

[0044] In one embodiment, the number of the air blowing cylinders 423 is multiple. The multiple air blowing cylinders 423 are arranged at intervals on the connecting plate. The connecting plate is connected to the power output end of the second driving member 422. It can be understood that the second driving member 422 drives the connecting plate to move to drive the multiple air blowing cylinders 423 to move, so that the multiple air blowing cylinders 423 abut against the corresponding filter elements on the fixture 230, that is, multiple filter elements are detected in one process, and the detection efficiency is improved.

[0045] As Figure 4As shown, in one embodiment, the pressing detection component 410 includes a second bracket 411, a third driving member 412, a pressing plate 413, and a detection member 414. The second bracket 411 is installed on the frame 100. The second bracket 411 is disposed opposite to the first bracket 421. The third driving member 412 is connected to the second bracket 411. The power output end of the third driving member 412 is connected to the pressing plate 413. The detection member 414 is installed on the pressing plate 413. The third driving member 412 drives the pressing plate 413 to abut against the fixture 230 and makes the detection end of the detection member 414 extend into the filter element. It can be understood that when the conveying rack 210 moves to a preset position, the third driving member 412 drives the pressing plate 413 to move, so that the detection member 414 on the pressing plate 413 moves and is in close contact with the filter element, and the pressing plate 413 is also in close contact with the end face of the fixture 230, so that the pressing plate 413 presses the filter element and makes the detection end of the detection member 414 extend into the filter element. At this time, the air blowing cylinder 423 is correspondingly located at the bottom surface of the filter element, and the air blowing cylinder 423 blows air into the filter element. The detection member 414 detects the air pressure passing through the filter element to determine whether the airtight performance of the filter element is good, so as to facilitate the subsequent blanking mechanism 500 to screen the qualified or unqualified filter elements. Further, the third driving member 412 is a motor or a cylinder, which is used to drive the pressing plate 413 to move in the vertical direction, so that the pressing plate 413 approaches or moves away from the fixture 230. The detection member 414 is a pressure sensor to detect the air pressure passing through the filter element.

[0046] As Figure 2 and Figure 5As shown, in one of the embodiments, the airtightness detection device further includes a flattening mechanism 600. The flattening mechanism 600 is located between the feeding mechanism 300 and the detection mechanism 400. The flattening mechanism 600 includes a third bracket 610, a fourth driving member 620, and a flattening plate 630. The third bracket 610 is installed on the frame 100. The fourth driving member 620 is connected to the third bracket 610. The power output end of the fourth driving member 620 is connected to the flattening plate 630. The fourth driving member 620 drives the flattening plate 630 to move and abut against a plurality of the filter elements, so that the plurality of filter elements on the fixture 230 are located on the same horizontal plane. It can be understood that a plurality of grooves are provided on the fixture 230. The feeding mechanism 300 places the filter elements into the grooves of the fixture 230 one by one. However, at this time, the filter elements in the plurality of grooves have different depths, which will affect the accuracy of the detection. In this embodiment, after the feeding mechanism 300 places a plurality of filter elements into the corresponding grooves of the fixture 230, the first driving member 220 drives the conveying frame 210 to move to the flattening mechanism 600. At this time, the fourth driving member 620 drives the flattening plate 630 to move, so that the flattening plate 630 abuts against the fixture 230. During the process of the flattening plate 630 contacting the fixture 230, the flattening plate 630 presses the filter elements into the grooves to ensure that the plurality of filter elements are located on the same horizontal plane, that is, the plurality of filter elements are located on the same horizontal line within the fixture 230, so as to avoid the problem of poor detection accuracy caused by different depths of the plurality of filter elements during the subsequent detection process, and further improve the detection accuracy. Further, the fourth driving member 620 is a motor or a cylinder.

[0047] As Figure 2 and Figure 6As shown, in one embodiment, the feeding mechanism 300 includes a vibrating feeding tray 310, a fourth bracket 320, a material rack 330, a sensing member 340, a fifth driving member 350 and a moving assembly 360. The vibrating feeding tray 310 and the fourth bracket 320 are both mounted on the frame 100, the fifth driving member 350 is mounted on the fourth bracket 320, the power output end of the fifth driving member 350 is connected to the material rack 330, and the material rack 330 is provided with a material The sensor 340 is installed on the fourth bracket 320 and the sensing end of the sensor 340 is facing the material slot 331. The fifth driving member 350 drives the material slot 331 to be connected or staggered with the feeding channel of the vibrating loading plate 310. The moving component 360 is installed on the frame 100. The moving component 360 is used to move the filter element in the material slot 331 to the clamp 230 of the conveying frame 210 when the sensor 340 releases a signal. In this embodiment, the vibrating loading tray 310 conveys the filter element to the material rack 330 by vibrating the loading material, and the fifth driving member 350 drives the material rack 330 to move so that the material slot 331 of the material rack 330 is connected with the conveying channel of the vibrating loading tray 310. At this time, the filter element enters the material slot 331. After the sensing member 340 senses the filter element in the material slot 331, it releases a signal to make the fifth driving member 350 drive the material rack 330 to move so that the material slot 331 is staggered with the vibrating loading tray 310. At this time, the moving assembly 360 receives the signal and conveys the filter element on the material slot 331 to the fixture 230. Further, the sensing member 340 is a sensor, and the fifth driving member 350 is a motor or a cylinder.

[0048] like Figure 2 and Figure 6As shown, in one embodiment, the moving component 360 includes a fifth bracket 361, a first horizontal driving member 362, a first vertical driving member 363, and a first vacuum suction cup 364. The fifth bracket 361 is installed on the frame 100. The first horizontal driving member 362 is connected to the fifth bracket 361. The power output end of the first horizontal driving member 362 is connected to the first vertical driving member 363. The power output end of the first vertical driving member 363 is connected to the first vacuum suction cup 364. The first vacuum suction cup 364 is used to adsorb the filter element. In this embodiment, after the sensing member 340 releases a signal, the first horizontal driving member 362 drives the first vacuum suction cup 364 to move in the horizontal direction, and the first vertical driving member 363 drives the first vacuum suction cup 364 to move in the vertical direction, so that the first vacuum suction cup 364 abuts against the filter element on the material tank 331. After the first vacuum suction cup 364 adsorbs the filter element, the first horizontal driving member 362 and the first vertical driving member 363 will drive the first vacuum suction cup 364 to move to place the filter element into the fixture 230 of the conveying rack 210. Further, the first horizontal driving member 362 and the first vertical driving member 363 are cylinders or motors.

[0049] As Figure 2 and Figure 7 As shown, in one embodiment, the blanking mechanism 500 includes a good product blanking component 510 and a defective product blanking component 520. The good product blanking component 510 and the defective product blanking component 520 are arranged adjacent to each other on the frame 100. The good product blanking component 510 is used to move and convey the good filter elements on the fixture 230 into the first collection box 518. The defective product blanking component 520 is used to move and convey the defective filter elements on the fixture 230 into the second collection box. It can be understood that after the detection mechanism 400 detects the filter elements in the fixture 230, the filter elements in the fixture 230 are marked and the data is uploaded to the control system. When the conveying rack 210 moves to the good product blanking component 510, the qualified filter elements in the fixture 230 are blanked and collected in the first collection box 518. When the conveying rack 210 moves to the defective product blanking component 520, the defective filter elements in the fixture 230 are blanked and collected in the second collection box. In this way, by classifying and blanking the filter elements, manual operation is reduced, and the production efficiency is further improved.

[0050] As Figure 2 and Figure 7As shown, in one embodiment, the qualified product discharging assembly 510 includes a sixth bracket 511, a second horizontal driving member 512, a second vertical driving member 513, a second vacuum suction cup 514, a seventh bracket 515, a sixth driving member 516 and a first ejector rod 517. The sixth bracket 511 is installed on the frame 100. The second horizontal driving member 512 is connected to the sixth bracket 511. The power output end of the second horizontal driving member 512 is connected to the second vertical driving member 513. The power output end of the second vertical driving member 513 is connected to the second vacuum suction cup 514;

[0051] The seventh bracket 515 is installed on the frame 100. The sixth driving member 516 is connected to the seventh bracket 515. The power output end of the sixth driving member 516 is connected to the first ejector rod 517. The sixth driving member 516 drives the first ejector rod 517 to move to eject the filter element out of the fixture 230, so that the second vacuum suction cup 514 adsorbs the filter element into the first collection box 518. It can be understood that when the conveying rack 210 moves to the qualified product discharging assembly 510, the qualified product discharging assembly 510 discharges the filter elements determined to be qualified on the fixture 230. However, at this time, since the filter element is embedded in the groove of the fixture 230, it is difficult for the second vacuum suction cup 514 to directly adsorb the filter element. Therefore, in this embodiment, the sixth driving member 516 drives the first ejector rod 517 to move in the vertical direction, so that the first ejector rod 517 ejects the filter element in the fixture 230. At this time, the second vacuum suction cup 514 is driven by the second horizontal driving member 512 and the second vertical driving member 513 to move above the filter element. After the filter element is ejected, the second vacuum suction cup 514 can adsorb the filter element, and the second horizontal driving member 512 and the second vertical driving member 513 drive the second vacuum suction cup 514 to move onto the first collection box 518 to put the qualified filter element into the first collection box 518. Further, the second horizontal driving member 512, the second vertical driving member 513 and the sixth driving member 516 are motors.

[0052] In one embodiment, the defective product discharging assembly 520 includes an eighth bracket, a third horizontal driving member, a third vertical driving member, a third vacuum suction cup, an eighth bracket, a seventh driving member and a second ejector rod. The eighth bracket is installed on the frame 100. The third horizontal driving member is connected to the eighth bracket. The power output end of the third horizontal driving member is connected to the third vertical driving member. The power output end of the third vertical driving member is connected to the third vacuum suction cup;

[0053] The eighth bracket is installed on the frame 100. The seventh driving member is connected to the eighth bracket, and the power output end of the seventh driving member is connected to the second ejector rod. The seventh driving member drives the second ejector rod to move to eject the filter element out of the fixture 230, so that the third vacuum suction cup adsorbs the filter element into the first collection box 518. In this embodiment, when the conveying rack 210 moves to the defective product discharging assembly 520, the seventh driving member drives the second ejector rod to move in the vertical direction, so that the second ejector rod ejects the filter element in the fixture 230. At this time, the third vacuum suction cup is driven by the third horizontal driving member and the third vertical driving member to move above the filter element. After the filter element is ejected, the third vacuum suction cup adsorbs the filter element, and the third horizontal driving member and the third vertical driving member drive the third vacuum suction cup to move above the second collection box to put the defective filter element into the second collection box.

[0054] As Figure 2 and Figure 3 shown, in one embodiment, the conveying rack 210 is a rotating bracket, and the feeding mechanism 300, the detecting mechanism 400, and the discharging mechanism 500 are arranged around the conveying rack 210, so that the fixture 230 on the conveying rack 210 passes through the feeding mechanism 300, the detecting mechanism 400, and the discharging mechanism 500 in sequence. In this embodiment, the conveying rack 210 is a rotating bracket and has a circular structure. The feeding mechanism 300, the detecting mechanism 400, and the discharging mechanism 500 are arranged around the conveying rack 210. In this way, the space utilization rate inside the device is improved, the structure of the device is more compact, and it is convenient for miniaturized design.

[0055] It is understandable that the air blowing assembly is provided with a plurality of air blowing cylinders to simultaneously detect a plurality of filter elements on the fixture, which is convenient for improving the detection efficiency. In order to ensure the accuracy of the detection, it is necessary to ensure that the air pressure blown out by each air blowing cylinder is consistent. However, since each air blowing cylinder is connected to the air outlet of the air pump through a pipeline, and the distance between each air outlet and the corresponding air blowing cylinder is inconsistent, that is, the length of the pipeline is also inconsistent, there is a problem that the air pressure entering the air blowing cylinder is inconsistent. To solve the above problems, in one embodiment, the air blowing assembly further includes a pressure regulating valve and a plurality of pressure reducing valves. The pressure regulating valve is arranged at the air outlet of the air pump, and the pressure regulating valve is used to regulate the air pressure of each air outlet of the air pump so that the air pressure blown out by a plurality of air outlets is kept consistent. The pressure reducing valves are arranged in one-to-one correspondence with the air blowing cylinders, and the pressure reducing valves are used to regulate the air pressure blown out by the air blowing cylinders so that the air pressure blown out by a plurality of air blowing cylinders is kept consistent. In this embodiment, the pressure regulating valve is arranged at the air outlet of the air pump, and the pressure regulating valve is used to control the air pressure of each air outlet of the air pump so that the air pressure of each air outlet is kept consistent. In this way, through the pressure regulating valve for shunt pressure regulation, the air pressure blown out by each air outlet of the air pump is kept consistent, which is the first pressure regulation. Further, since the structure of the filter element is small, if the detection is carried out through the filter element with a relatively large air pressure, the error range is relatively large. Therefore, in order to ensure that the air pressure blown out by the air blowing cylinder is within the preset value, a pressure reducing valve is provided on each air blowing cylinder. The pressure reducing valve is used to regulate the air pressure blown out by each air blowing cylinder, that is, to regulate the air pressure entering the air blowing cylinder from the pipeline again, so as to accurately control the air pressure blown out by the air blowing cylinder and keep the air pressure blown out by a plurality of air blowing cylinders consistent, which is the secondary pressure regulation. For example, the output air pressure of the air pump is 0.7 kg, and the output air pressure of the air pump is shunted through the pressure regulating valve so that the air pressure entering a plurality of air blowing cylinders is 0.5 kg. However, at this time, due to the inconsistent pipeline length of each air blowing cylinder, the air pressure entering the air blowing cylinder may be inconsistent. Then, the air pressure blown out by the air blowing cylinder is controlled through the pressure reducing valve so that the air pressure blown out by the air blowing cylinder is 0.05 kg, so as to ensure that the air pressure blown out by the air blowing cylinder reaches the preset value, and at the same time, the air pressure blown out by a plurality of air blowing cylinders is also made consistent. In this way, through the cooperation of the pressure regulating valve and the pressure reducing valve, the air pressure is regulated twice, so that the air pressure blown out by a plurality of air blowing cylinders is kept consistent, and the detection accuracy is further improved.

[0056] It is understandable that the driving member drives the air blowing cylinder 423 to move to abut against the filter element in the fixture 230, so that the air blowing port 4232 of the air blowing cylinder 423 enters the interior of the filter element. In order to ensure the airtightness between the air blowing cylinder 423 and the filter element, the air blowing cylinder 423 is in interference fit with the filter element. In this way, during the continuous abutting process, the air blowing cylinder 423 is likely to cause damage to the surface of the filter element, thereby affecting the performance of the filter element. To solve the above problems, as Figure 4As shown, in one of the embodiments, the air blowing assembly 420 further includes an elastic buffer 424 and a connecting plate. The connecting plate is connected to the power output end of the second driving member 422. The connecting plate is provided with an avoidance hole, the air blowing cylinder 423 passes through the avoidance hole, the elastic buffer 424 is sleeved on the air blowing cylinder 423, and both ends of the elastic buffer 424 are respectively abutted against the air blowing cylinder 423 and the connecting plate. In this embodiment, the elastic buffer 424 is respectively abutted against the air blowing cylinder 423 and the connecting plate. The second driving member 422 drives the connecting plate to move, so as to drive the air blowing cylinder 423 to move, so that the air blowing cylinder 423 abuts against the filter element. During the process that the air blowing cylinder 423 abuts against the filter element, the elastic buffer 424 is compressed, so that while the air blowing cylinder 423 is closely attached to the filter element, the stress of the air blowing cylinder 423 on the filter element is reduced, thereby avoiding damage to the filter element by the air blowing cylinder 423. Further, the elastic buffer 424 can adopt a spring or other elastic structures in the prior art.

[0057] Further, when the air blowing cylinder 423 abuts against the filter element 10a, the air blowing port 4232 of the air blowing cylinder 423 extends into the filter element 10a to blow air into the interior of the filter element 10a, and the outer side of the air blowing cylinder 423 abuts against the filter element 10a, so that the air blowing port 4232 of the air blowing cylinder 423 is sealed with the filter element 10a. However, at this time, there may be a gap at the junction where the outer side of the air blowing cylinder 423 abuts against the bottom surface of the filter element 10a, so that the gas easily flows out of the gap, thereby resulting in inaccurate detection. In order to improve the accuracy of detection, such as Figure 8As shown, in one of the embodiments, the air blowing cylinder 423 includes a cylinder body 4231, an air blowing port 4232 and a seal 423a. The cylinder body 4231 is in communication with the air blowing port 4232. The cylinder body 4231 is in communication with a pipeline. The cylinder body 4231 is installed on the connecting plate. The seal 423a includes an abutting portion 4233 and a sealing and covering portion 4234. The sealing and covering portion 4234 is connected to the periphery of the side surface of the abutting portion 4233 adjacent to the air blowing side. The abutting portion 4233 is sleeved on the connection junction of the air blowing port 4232 and the cylinder body 4231. The sealing and covering portion 4234 is used for press-fittingly abutting against the outer peripheral side of the filter element 10a when the bottom surface of the filter element 10a abuts against the abutting portion 4233. In this embodiment, the abutting portion 4233 and the sealing and covering portion 4234 are integrally formed. The abutting portion 4233 is sleeved on the connection junction of the air blowing port 4232 and the cylinder body 4231. When the connecting plate drives the cylinder body 4231 to move, the air blowing port 4232 first enters the inside of the filter element 10a. At this time, the bottom surface of the filter element 10a abuts against the abutting portion 4233. Since the diameter of the sealing and covering portion 4234 is larger than the diameter of the air blowing port 4232, and the diameter of the sealing and covering portion 4234 is equal to the diameter of the filter element 10a, the sealing and covering portion 4234 is deformed outwardly under the extrusion of the filter element 10a, so that the sealing and covering portion 4234 wraps the outer peripheral wall of the filter element 10a, and the sealing and covering portion 4234 press-fittingly abuts against the outer peripheral wall of the filter element 10a. In this way, the sealing performance at the junction where the filter element 10a abuts against the air blowing cylinder 423 is improved, and the gas is prevented from flowing out of the gap at the junction, thereby improving the detection accuracy. Further, the seal 423a can be made of materials such as silica gel or rubber, so that the sealing and covering portion 4234 is deformed under force to better wrap the periphery of the filter element 10a, and at the same time, the sealing performance between the filter element 10a and the air blowing port 4232 is ensured.

[0058] The present application also provides a filter element assembly device, including the airtightness detection device 10 for the filter element of an automotive ventilation seat described in any of the above embodiments.

[0059] Compared with the prior art, the present disclosure has at least the following advantages:

[0060] For the airtightness detection device 10 for the filter element of the automotive ventilation seat, the first driving member 220 drives the conveying rack 210 to sequentially pass through the feeding mechanism 300, the detection mechanism 400 and the discharging mechanism 500. The feeding mechanism 300 conveys the filter element onto the fixture 230 of the conveying rack 210. After the pressing detection assembly 410 moves, it abuts against the surface of the filter element on the fixture 230. After the air blowing assembly 420 moves, it abuts against the bottom surface of the filter element on the fixture 230, that is, the pressing detection assembly 410, the fixture 230 and the air blowing assembly 420 completely wrap the filter element. After the air blowing assembly 420 blows air into the filter element, the airtightness of the filter element is detected through the pressing detection assembly 410. In this way, the detection accuracy of multiple filter elements on the fixture 230 is improved simultaneously. After the detection is completed, the filter element is placed into the corresponding collection box through the discharging mechanism 500. In this way, through the whole-process automatic operation, the steps of manual operation are reduced, and the production efficiency is improved.

[0061] The above embodiments only represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
