Patent GB-627675-A (GB)
Title: Improvements in or relating to sewing machine
IPC: D05B65/00
Filed: 1947-08-08
Abstract: 627,675. Buttonhole sewing-machines. INTERNATIONAL BUTTON HOLE SEWING MACHINE CO. Aug. 8, 1947, No. 22012. Convention date, July 11, 1941. [Class 112] In a buttonhole sewing-machine, the buttonhole is cut, the last stitch set and the thread cut during the last revolution of the machine shaft and the actuation of the stitch-setting and thread-cutting plate 75 is dependent upon the proper return of the buttonhole cutter. The stop-lever 34 is fixed on a shaft 35 which, in starting the machine, is moved by a lever 68 towards the left in the plan view, Fig. 2, and is detained by a detent 69 entering a recess 70 in the shaft. In this movement the belt-shifter 33 carries the driving belt 30 on to the fast pulley 31. Before the last stitch is made, the detent 69 is withdrawn, the shaft 35 moves to the right under the pressure of a spring 65 and the stop-lever is returned into the stopping position, bringing a nose 43, Fig. 5, on the stop-lever into the path of the stop-cam 44. The cam-rise b tilts the stop-lever against the pressure of a spring 45 and thereafter the nose falls into the gap c and engages the stopping face d. The nose 43 is part of a rod 41 slidingly mounted in the stop-lever and pressed to the right by a spring 42 which takes the shock of the positive stop. A pin 57 on the stop-lever 34 has a sliding-turning engagement with the buttonhole cutter lever 51 so that the upward tilt of the stop-lever moves the cutter to cut the buttonhole. The return movement of the stop-arm under the pressute of the spring 45.raises the buttonhole cutter clear of the work and brings a lug 84 on the rod 41 into a gap 83 on a link 80 connected to a shaft 78 which actuates the plate 75. The movement of the rod 41 to the left, Fig. 5, in the positive stopping action actuates the plate 75 to set the last stitch and cut the thread. If the buttonhole cutter jambs, the spring 45 will not depress the lever 34 and the lug 84 will not enter the gap 83. The stopping face d is, however, sufficiently long to engage the nose 43 and cause the machine to stop, but the lug 84 will not move the link 80 and the plate 75 will not be actuated. The plate 75 has a blunt part e which engages the needle side of the last thread loop, which is on one of the loopers, to set the stitch and in the further movement of the plate a knife edge f cuts the other side of the loop. U.S.A. Specifications 714,284, 749,776, 1,088,652, 1,402,073 and 1,483,307 are referred to.

Abstract: 1369168 Microphones NATIONAL CASH REGISTER CO 9 May 1973 [17 May 1972] 22091/73 Heading H4J [Also in Divisions G4 and G1] An electro-mechanical transducer 10 includes first and second electrode means 11, 20 incorporating respective first and second conductive layers 12, 22, the first electrode means including an assembly formed by the first conductive layer and first and second insulator layers 14, 16, the interface of the insulator layers being capable of storing an electrical charge; the first and second electrode means being separated by an air gap 25 and one of the first and second electrode means being flexible. The second electrode means includes a third insulator layer 24 mounted on a face of the second conductive layer 22 directed towards the first electrode means. The thickness of the first insulator layer is greater than the thickness of the second layer, one of these layers being of silicon oxide and the other of silicon nitride. A third conductive layer 18 is provided on the second insulator layer. In use the interface is charged from battery 38 and switches 36, 37 and thereafter switches 36, 37 are opened and switch 28 is closed and application of an acoustical wave thereto or physical contact to the transducer causes the flexible electrode means 20 to vary the air gap whereby the voltage between layers 22 and 12 is changed and the voltage across load 30 indicates the force applied to means 20. The transducer may be used as a microphone. In an alternative embodiment for use as a coded output keyboard key, Figs. 2, 3 (not shown), the first and third conductive layers are formed by six isolated conductive electrodes (44, 48) respectively aligned relative to each other and the charging means applies charging potentials to a selected one or ones of the electrodes (44) will cause charge to be trapped only at the interface of the insulating layer(s) beneath the selected electrode(s) whereby subsequent depression of the flexible electrode (50) will cause a voltage change between the selected electrode(s) 44 and electrodes 48 but not between the others so that a coded output is obtained. For example if two electrodes only are charged an output 110000 will be obtained by depression of the flexible electrode.

Abstract: 1,262,193. Rotary-piston internal combustion engines. TOYO KOGYO CO. Ltd. May 1, 1969 [May 25, 1968], No.22318/69. Heading F1F. In a rotary-piston I. C. engine of the kind comprising a three-sided piston 3, which planetarily rotates within a housing defined by a two-lobed epitrochoidal inner peripheral surfaced closed on both sides by end walls and as shown includes peripheral inlet and exhaust ports 10, 11, nozzles 13, 14, 15 supplied with secondary air by a pump 17 are located in one or both end walls of the housing so that during the exhaust phase of piston rotation the nozzles are progressively opened and closed to continue combustion and oxidization of the exhausting gases to eliminate detrimental components such as carbon monoxide and hydrocarbon from the exhaust gases. The nozzles are arranged so that they are radially beyond the orbital path of the oil seal ring 8 and when the exhaust port 11 commences to open one of the nozzles, as shown the nozzle 13, opens to supply secondary air in sufficient quantity to continue combustion and oxidization of the exhausting gases without the temperature of the exhausting gases being lowered. As the piston continues to rotate the nozzles 14 and 15 successively open up to the full opening of the exhaust port 11, the temperature of the exhausting gases then being sufficiently high to cope with the extra secondary air required for further oxidization of the exhausting gases. On still further rotation of the piston the quantity of exhausting gas is reduced, along with the quantity of secondary air by the progressing closure of the nozzles 13, 14, 15. In another embodiment, the radially outermost nozzle 15 is arranged to open and close first and the radially innermost nozzle 13 last. The number of nozzles may be greater than three, not necessarily round and not necessarily arranged along a straight line.

Abstract: 1344369 Surgical drainage C J TIMMERMANS 19 April 1971 [20 Feb 1970] 22377/71 Heading A5R A suction jar comprises a vessel 1 consisting of a glass tube 2 received in a fixed foot 3 and a rim 4, the vessel 1 having a cover 5. The assembly is suspended from a bracket 6 secured to a wall 7. A flexible bag 8 has two nipples (10), (11) Fig. 2 (not shown) secured to its upper wall (13). Nipple 10 extends into the interior of bag 8 to the bottom thereby forming a dip-pipe 12. Nipple (11) terminates at the upper wall (13). Nipples (10), (11) extend through cover 5 in sealing relationship so that when cover 5 has been positioned on vessel 1 two separate spaces are formed 14, 15, space 14 between the flexible bag 8 and the interior wall of vessel 1, and space 15 the interior of flexible bag 8. Connected to rim 4 is a tube coupling 16, one part 16a of which is secured to bracket 6, the other part 16b secured to rim 4. Through coupling 16, which is also a mechanical coupling and partly carries vessel 1, space 14 is connected with conduit 17 leading to a vacuum device, not shown, through valve 25. Conduits 20, 21 are connected to nipples 10, 11 respectively, conduit 20 being placed in a body cavity of a patient and conduit 21 leading to a vacuum device via a reducing valve.22 for controlling the vacuum. In operation, a vacuum is applied to space 14, whereby the flexible bag 8 expands and is drawn smoothly against the interior wall of vessel 1. Then suction is applied through conduit 21, whereby the body cavity of the patient is evacuated through conduit 20 and dip-pipe 12. Disinfectant placed in the bottom of bag 8 also acts as a liquid seal so that should the vacuum in the bag 8 become too high this can at once be visually observed by the rising in the bag 8 of the liquid. When evacuation is completed, or the replacement of bag 8 is necessary, coupling 16 is disconnected and the vacuum is released in space 14, coupling part 16a automatically shutting off its opening. In order to facilitate the operation of the suction jar conduits 17, 26, 21 are controlled by a threeway valve 25. The valve 25 is connected to conduit 21, conduit 17, suction conduit 26, and to atmosphere through conduit 27. A throttle 29 is provided in conduit 17 to ensure that atmospheric pressure is not restored more rapidly in space 14 than in bag 8.
