Filed: 1919-02-26
Abstract: 145,107. Rawlings, A. D., and Rawlings, E. J. Feb. 26, 1919. Vehicle-window opening and closing apparatus.-In sash-operating mechanism as described in Specification 17975/15, means are provided for re-winding the pull-cord when the sash is moved. The sash is raised by fusee barrels and cord 4, 5, the barrels 4 being fast to a drum 3 controlled by a spring 2 adjustably held at one end by the spindle 1 and ratchet-wheel and pawl 15, 16. The pull-cord 20 operates a drum 22, and after use is re-wound by a clock spring 24 fixed to the casing 6 and to a drum 23 connected to 22. The drum 22 drives the drum 3 through a coiled-wire clutch 29, one end of which is connected to a collar 28 rotatably mounted on the drum 3 and braked by a blade spring 27 bearing on a sleeve 25 which is braked by a strip 26 secured to the casing. In a modification, the spring 22 projects through a slot and is bent over to engage a collar frictionally held like the collar 25.

Title: Improvements in or relating to bucky grids for x-ray apparatus
IPC: H01J29/02
Filed: 1953-02-24
Abstract: 724,425. X-ray apparatus. WESTING- HOUSE ELECTRICAL INTERNATIONAL CO. Feb. 24, 1953 [March 29, 1952], No. 5108/53. Drawings to Specification. Class 98 (1). A Bucky grid is made of a spiral ribbon of material of high atomic weight, the spaces between the convolutions being filled with a material containing carbon particles bound with a substance containing no atom of atomic weight substantially greater than that of chlorine. The grid may be made by winding into a spiral a composite ribbon having a layer of material of high atomic weight faced on one side with a layer of hardenable material containing carbon atoms bound with a substance containing no atom of atomic weight greater than that of chlorine, one edge of one of the layers being thicker than the other, and hardening the resultant body. The grid may be used with or within an electronic image intensifier, and may be made to withstand the high temperatures encountered during the manufacture of the tube. The ribbon may be made of a heavy metal such as gold, tungsten, tantalum or molybdenum. The material between the convolutions may be made by mixing carbon powder with polyvinyl alcohol and ethyl borate to form a plastic mass. The ethyl borate may be replaced by borax, or other glassy low atomic weight material such as a phosphate. Alternatively, magnesium oxide is mixed with a silicone binder. The metal ribbon is coated with the plastic mass and wound into a spiral. The ribbon is wound so that its broad surfaces converge on a point, e.g. by making either the metal ribbon or the plastic layer, or both, wider at one edge than the other. Alternatively, the plastic may be exposed at one edge to vapours which cause it to swell. If the grid is to conform to a spherical surface, the wound spiral is pressed against a similar surface. The grid is then baked.

Title: Improvements in electrical safety switch devices
IPC: H01H35/00
Filed: 1945-03-16
Abstract: 588,246. Retractive switches. LEACH, F., and BRADSHAW, K. March 16, 1945, No. 5238/44. [Class 38 (v)] A safety electric switch comprises two concentric tubes, the inner one carrying co-operating switch contacts and the outer one so disposed that radial movement in any direction operates the switch against a spring. Fixed to a tube 9 is a block 14 carrying a fixed contact 22 against which a moving contact 24 mounted on an arcuate strip 15 pivoted at 17 is urged by a spring 20. A conical surface on the end of a sleeve 5 free to slide on the tube 9 is urged by a spring 6 into engagement with a similarly shaped recess 2a in a sleeve 2 carried by an outer tube 8 which is concentric with the inner tube 9 and cannot move longitudinally because the switch arrangement is repeated at the other end of the tubes 8, 9. When radial movement of the tube 8, which is allowed by the hole in the sleeve 2 being of larger diameter than the tube 9, occurs, the cam-action at conical surface 2a moves the sleeve 5 to the right and through a rod 23 which slides in the block 14 moves the spring strip 15 to open the contacts 22, 24. When pressure is removed from the tube 8 it returns to its original position and contacts 22, 24 close. Alternatively they may be arranged normally open. Mention is made of the use of device as an emergency stop, a safety guard for rolling mills and other machinery, a "dead-man" gripper bar and a granule sorter. Where two or more switches are provided they may be connected in series.

Title: Improvements in or relating to wheel suspension
IPC: B60G7/00
Filed: 1949-02-28
Abstract: 664,269. Vehicle suspensions. THOMPSON PRODUCTS, Inc. Feb. 28, 1949 [May 1, 1948], No. 5359/49. Class 108(ii) In a vehicle wheel suspension comprising upper and lower control arms connected by joints to a wheel carrier, the lower joint is provided with anti-friction bearings so arranged that the weight of the vehicle is taken by such bearing in compression. As shown in Fig. 1, the wheel carrier 10 is connected to upper and lower arms 15, 18 by ball joints 14, 17 of which the lower is arranged to support the weight of the vehicle through a coil spring (not shown). The lower arm 18 has integral therewith a ball socket 50 containing a hemispherical bearing member 55 which has an axial hole 55c. A hemispherical ball member 56a, secured by its tapered shank 60 in the wheel carrier 10, has a projecting axial pin 56d which enters the hole 55c, and is separated from the hemispherical bearing member 55 by a roller bearing 57. The hemispherical ball member 56a is retained by a complementary socket member 59 screwed into the bottom of the socket 50 and held in position by a cotter pin 54. During steering movements the bearing member 55 remains stationary, the pin 56d rotating therein. During vertical movements of the wheel carrier the whole ball assembly oscillates within its socket. A grease nipple 50a and a mud-excluding shield 58 may be provided. The upper arm 15 has integral therewith a socket 27 containing a hemispherical bearing shell 30 with a central hole 48, (see also Fig. 2). The ball 32, secured by its tapered shank 35 in the wheel carrier 10, has a projecting pin 47 which engages the hole 48, and is retained in the socket by a threaded member 38 as before. During steering movements, the ball rotates in the socket and in the hemispherical bearing shell 30, but during vertical movements of the wheel carrier, the bearing shell 30 is moved by the pin 47 on the ball. The modified form of ball joint is shown in Fig. 4, also adapted to take thrust, may replace the lower ball joint of Fig. 3. In this case thrust is taken by the anti-friction thrust bearing 69 interposed between the lower half socket 12 and the bottom of the cylindrical bore 71a.

Abstract: 853,631. Diaphragm valves. FORTUNE, R. Feb. 18, 1957 [Feb. 17, 1956], No. 5370/57. Class 135. A diaphragm valve assembly comprises a valve body A with inlet and outlet passages 1 both leading to a flow chamber 3 having opposed opening surrounded by flanges 4, dish-shaped flexible diaphragms 8 clamped between the flanges 4 and matching flanges 5 on valve bonnets C, and a central bridge member B arranged transversely in the chamber 3 and provided with transverse seats or weirs 12 curved towards one another for the diaphragms 8. The diaphragms may be operated simultaneously or independently and when both are fully raised from their seats, two flow paths of equal flow capacity are provided between the inlet and outlet passages. Each diaphragm 8 has on its outer side a boss with a rigid insert 17 connected by a screw 34 to a compressor 22 prevented from rotating by horns 31 in grooves 66. A threaded stem 26 with a head or flange 27 is secured to each compressor 22 by a flanged retaining cap 24. A key 29 on the head 27 engages a slot 30 as described in Specification 701,026. Axial movement of the stems 26 to operate the diaphragms is effected by internally-threaded flanged sleeves 61 rotatably mounted in the bonnets. The bridge member B has a bore 37 containing flanged bearings 38, 41 for mounting a shaft 48. The shaft 48 carries a hand wheel 51 at one end and a bevel gear 54 at the other. The bearing 38 forms the trunnion of a frame 39 supporting aligned countershafts 56. Each countershaft carries a bevel gear 57 meshing with the gear 54 and also a spur gear 58 meshing with a further spur gear 59 on the respective sleeve 61. Thus rotation of the hand wheel 51 moves the diaphragms 8 to or from their seats simultaneously. The frame 39 is anchored by a pin 67 engaging aligned lugs. Either flow control orifice may be closed and then retained closed by removing the corresponding pinion 58 and using the respective pinion 59 as a hand wheel. The gearing may be dispensed with entirely and the spur gears 59 replaced by separate hand wheels.
