Title: Fluid pressure control valve
IPC: F15B13/04
Filed: 1958-09-16
Abstract: 838,686. Valves. NEW YORK AIR BRAKE CO. Sept. 16,1958 [Dec. 11, 1957], No. 29594/58. Class 135.. A valve comprises a housing 11 having inlet ports 32, 22, 24 and exhaust ports 23, 33 and first and second motor ports 19, 26 and a valve 35 movable to five positions to control passageways interconnecting the ports. In the neutral position of Fig. 2 pressure fluid passes from the inlet through the casing of a by-pass relief valve to the exhaust via piston grooves 36, 37 and around land 41 centralized in the exhaust chamber. Both motor ports are closed by the remaining lands 39, 42. The valve may be moved to the left or right to supply fluid to one of the motor ports and exhaust the other. In one of these positions land 41 closes the connection between inlet and exhaust via groove 37 and pressure fluid flows from the inlet via valve port 49 and passage 44 to open check valve 54 and pass through port 48 to the outlet 19. Inlet pressure also reaches port 49 via groove 37, passages 25, 30, 21 and enlarged valve bore 31. Exhaust takes place via ports 26, 52, valve passage 45 and port 51 opening into the outlet. In the first position to the left of the neutral position for the valve, land 41 closes the connection between the inlet and exhaust and inlet pressure is applied to the other outlet via ports 51, 52, passage 45, and port 53. The exhaust takes place via port 49, passage 44, check valve 54, port 48, passage 18, and end counter-bore 29 and exhaust 33. Movement of the valve to its first two positions is against a centralizing spring 63 accommodated between abutments 62, 64, slidable on the valve and alternately engaging abutments on the valve and on a casing sleeve 61. On further movement of the valve to the left an inclined groove 59 on the sleeve 61 forces a circular spring 68 into a casing groove 57 so that the valve and sleeve 61 take up the position shown in Fig. 5, whereby the motor ports are interconnected via valve ports 51, 53 and passage 45 and are also connected to inlet and exhaust via port 51, grooves 36, enlarged bore 31 and groove 37. Ports 51, 53 are also interconnected via passages 21, 30, 25. This position of the valve allows free movement of the motor for back-dragging when controlling a bull-dozer blade. The valve may be moved to its fifth position against spring 63, as shown in Fig. 6, in which case both sides of the motor, the inlet and the exhaust are all connected but instead of there being a free connection between the inlet and the exhaust via groove 37, this connection is closed and inlet pressure passes to exhaust via enlarged bore 31, groove 36, port 51, passage 45 and a restricted opening of port 52 with outlet passage 23. This ensures that when the bull-dozer blade is dropping, sufficient inlet pressure is applied to the expanding chamber of the motor to prevent cavitation.

Title: Telephone instrument
IPC: H04M1/02
Filed: 1960-08-29
Abstract: 921,292. Sets. TELEFONAKTIEBOLAGET L. M. ERICSSON. Aug. 29, 1960 [Aug. 31, 1959; June 13, 1960], No. 29718/60. Class 40 (4). In a telephone set certain components e.g. the transmission parts, are mounted on a mounting plate which is connected to a hook switch frame to form a first mounting unit, lugs on the frame engaging suitable slots in a base plate of the set so that displacement of the unit in one direction only is possible, while a second frame for holding the dial for example, to form a second mounting unit has some further lugs which engage further holes in the base plate so as to lock the first mounting unit against displacement in said one direction. A bell set attached to a mounting plate with suitable lugs thereon can also be mounted on the base plate and is restrained from movement by co-operation with the first and second mounting units while a casing for the instrument serves to lock the second mounting unit (dial assembly) in position. In Fig. 1, a bell set 1 is attached to mounting plate 2 and is retained on the base plate 36 by the engaging of a lug 6 with a hook 7 formed in the base plate. When hook switch frame 42 (Fig. 17) to which is riveted a printed circuit board 44, is attached to the base by inserting lugs 133a, 133b and 46 into holes 49b, 49a and 48 respectively and then sliding the unit as a whole in the direction of the arrows P2, then the bell set 1 will be locked in position. The dial frame 45a, 45b is then located in the hook switch frame 42 by lugs 113a, 113b and, by pulling legs 115a, 115b apart, lugs 116a, 116b can enter holes 117a, 117b thus engaging the base plate. In order to allow for manufacturing tolerances and deformation of the printed circuit board 44, arms 118a, 118b of legs 115a, 115b are twisted so that lugs 119a, 119b can engage holes 120a, 120b, arms 118a, 118b then being pressed firmly against the respective shoulders of board 44. The edges of the hole in the casing (not shown), for the dial, bear against frame 45a, 45b so as to lock the latter component in position. In another embodiment the legs (115) are pulled slightly together so that the lugs can engage suitable holes formed in the base plate, and in this case the printed circuit board is trapped between the base plate and the upper faces of the grooves in the lugs (116a, 116b).
