Title: Improvements in or relating to drive mechanisms
IPC: G11B15/32
Filed: 1953-09-09
Abstract: 727,125. Friction clutches. GRUNDIG, M. Sept. 9, 1953 [Sept. 20, 1952], No. 24959/53. Class 80 (2) [Also in Groups XVI and XXXVIII]. In a mechanism for driving in alternate directions a magnetic or other record tape or similar medium 19 on reels, a reversible motor shaft 2 carries two freewheel clutches 3, 4 adapted to drive the winding support plates 34 in opposite directions to each other. The support plates are driven by a belt 5 arranged as shown in Fig. 1, and always rotate in the same direction irrespective of the direction of the motor 1. When tape is driven from the lefthand position to the righthand position as seen in Fig. 1 the belt 5 is driven by freewheel clutch 4 which is rotated clockwise by the motor 1 rotating in that direction. A capstan 16 accordingly drives the tape towards the righthand spool. When the motor is driven in this direction an electro-magnetic clutch 38, 39 in the righthand support is operated to lift the rotating member 32 into strong frictional contact with a disc 33 which in turn is coupled to the support 34 by a light frictional contact whereby the reel thereon is driven with an element of slip. A frictional drag is produced in the supply reel support by means of a coil spring 35 (wound in the lefthand support in the opposite direction to that shown in Fig. 2), and serves to lock plate 33 to the solid centre shaft 31 when the spool on the support 34 rotates in the opposite direction to the member 32. When tape is to be wound on to the lefthand spool the motor 1 is reversed and a similar electromagnetic clutch in the lefthand support becomes operative. A further electromagnetic clutch 43, 44 is provided for positively locking disc 33 and support 34 together when a fast forward or reverse winding is required.

Title: Improvements in and relating to control valve arrangements with automatic return of longitudinally movable control members for hydraulic installations for moving structural parts of aircraft
IPC: B64C25/22
Filed: 1938-08-26
Abstract: 518,550. Hydraulic control valves. ELEKTRON CO. Aug. 26, 1938, No. 25153. Convention date, Sept. 17, 1937. [Class 135] A manually-operable control valve device for the hydraulic apparatus used for moving the movable parts of aeroplanes such as landing flaps, shock absorbing tail skids, retractable undercarriages &c. is arranged so that after the end of the working stroke of the power cylinder the rise of pressure in the supply conduit opens an excess pressure valve which permits pump pressure to act on the end surface of the valve and initiate its return movement, which movement is completed by the idle running pressure in the return flow conduit caused by the insertion of throttling means in said conduit. The Fig. shows a double-acting piston 20 working in a cylinder 24 connected by pipes 21, 25 to a pair of control valves mounted in a single casing. Each valve, which comprises a piston valve member hydraulically balanced except for pressure on the end face 11 is provided with a packing 4 and an actuating push-button 5. If the button 5 is depressed, pressure fluid from the conduit 13 passes through valve port 7 and pipe 21 to the power cylinder while fluid is exhausted from the other side of the piston through pipe 25 valve port 10 and conduit 23. When the power piston reaches the end of its stroke use of pressure in the conduit 13 lifts excess pressure valve 16 so allowing pump pressure to act on surface 11 to initiate the return movement of the valve. As the control valve reaches the piston in which the return flow circuit 13, 7, 14, 9, 17 is re-established the pressure in this circuit is transmitted to the surface 11 through the pipe 17 to complete the return movement. A throttle 18 is arranged between the pipes 17, 15 to maintain a minimum pressure in the return flow circuit. Specification 480,180 is referred to.
