Abstract: 724,730. Automatic gramophones. PAILLARD SOC. ANON. May 4, 1953 [May 28, 1952], No. 12252/53. Class 40 (2) A centre post for an automatic gramophone has a retractable pawl 6 which unseats the lowermost record and is movable axially by an amount corresponding to the thickness of a record to lower the remainder of the stack on to a bearing surface 4 on the centre post, and another pawl 25 acting diametrically opposite to the other pawl 6 and forming a second bearing surface, whereby the records are prevented from tilting. The pawls 6, 25 are movable about a fixed pin 7 in the centre post, the pawl 6 being provided with an elongated hole 11 to permit limited axial movement. The pawl 6 is normally held in its uppermost position by a spring-loaded plunger 19 acting on a ramp 20 on the pawl 6. During a record changing operation, an inner shaft 12 carrying the plunger 19 and a pin 14 is moved upwardly to move the pawls 6 and 25 to the left, as viewed in Fig. 2, to unseat the lowermost record a. The weight of the remaining records press the pawl 6 downwardly against the spring-loaded plunger 19, following which the pawls 6 and 25 are immediately moved back to the initial position shown in Fig. 2 so that pawl 25 also supports the records at a point diametrically opposite to the surface 4. When records are withdrawn from the centre post, the pawls 6 and 25 are automatically pressed into their retracted position by the records being removed.

Abstract: 725,610. Regulating ; supercharging. GENERAL MOTORS CORPORATION. May 11, 1953 [May 27, 1952], No. 13010/53. Classes 7 (2) and 7 (6). A fuel supply control system for a supercharged fuel injection engine comprises a fuel injection pump control element 34 biased towards the maximum fuel position and controllable by a manual control device 76 which also controls a throttle valve 18 in the inlet of the blower 12, the limit of movement of the control element 34 to increase the fuel supply being adjustable by means 116 responsive to blower output pressure. The control element 34, Fig. 2, connected by a pin 42 to a lever 36 pivoted at 38 and loaded by a spring 43 to urge the member 34 to the right to its maximum fuel position, is actuated from a control pedal 76 through a cam lever 68, push rod 62 and a lever 60 connected to a shaft 50 on which is fixed a lever 52 carrying a pin 56 adapted to engage one side of the lever 36. The cam 68 is pivoted at 66 and has a cam surface 70 engaging a pin 72 on the rod 62, the end of which is forked and guided by the shaft 66. On release of the pedal 76 from the fully depressed position shown in Fig. 2, the cam surface 70 forces the rod 62 upwards to rotate the shaft 50 and lever 52 anti-clockwise, whereby the member 34 is moved to the left to reduce the fuel supply. The throttle valve 18 at the inlet of the supercharger 12 supplying a supercharging air receiver 10 in the cylinder block is controlled conjointly with the fuel supply by a rod 22 connected to the cam lever 68. The shaft 50 is eccentrically journalled in a rotatable shaft 100 connected through a lever 110 and rod 112 to a diaphragm 114 controlled by the supercharging pressure transmitted through a pipe 26, increase in the supercharging pressure causing clockwise rotation of the shaft 100 which raises the shaft 50 and moves the pin 56 away from lever 36 to allow the spring 43 to move the rod 34 to increase the fuel supply. When the pedal 76 is fully released to close the throttle valve 18 a notch 84 on the cam surface 70 causes the pin 56 to move away from the lever 36 and the idling fuel is then controlled entirely by a diaphragm 92 connected by a rod 94 to the lever 36 and actuated by the suction in a small Venturi 20 in the supercharger inlet transmitted through a pipe 24. The lever 60 may be rotated anticlockwise by a rod 82 to cut off the fuel. In a modification of the above apparatus the eccentric shaft 100 is omitted and the diaphragm 114, Fig. 7, actuated by supercharger delivery pressure actuates a cam 138 which co-operates with a roller 140 carried by the control element 34. Specification 685,899 is referred to.

The cartridges 20 are mounted on a horizontally disposed slideway consisting of spaced decks 12, 14 and sides 16, 18. The stack of cartridges are advanced by means of a leader plate 62 and follower plate 64. When it is desired to remove or place a cartridge in the stack, levers 120, 128, Fig. 1B, are squeezed to enable plate 62 to be moved relative to plate 64. Plate 62 has legs 66, 68 which slide in slots 66a, 68a in lower deck 14, Fig. 5. Legs 66, 68 are attached to hollow slide members 70, 72 which are movable along guide bars 74, 76 of the tape recorder frame by means of a motor 94, Fig. 1B, which drives a worm gear 80 and shaft 82 meshing with a rack 78 associated with slide member 70. Plates 62, 64 may be locked to each other at varying distances apart depending on the number of cartridges in the holder so that all the cartridges are moved simultaneously. A feeler (324), Fig. 9 (not shown), on a switch operating member (322) engages a gap 26, Fig. 1B between adjacent cartridges to centrally locate the leading cartridge under heads 57, 58, 59. When feeler (324) senses a gap 26 switch (320), Fig. 9, is closed to operate a relay (400), Fig. 14 (not shown), which stops transport motor 94 and starts a motor 140, Fig. 1A. Motor 140 operates capstan shaft 152, Fig. 1B and a reel drive shaft 156 which is positionable through reel drive openings in a plurality of cartridges 20. Shaft 156 is provided with a spring pressed pawl 159 which drivingly engages in slot 34 in reel 28. When a tape has been played a switch 264, Fig. 5, is closed by the tension of the tape to energize solenoid 270, Fig. 1A. This causes a rod 280 to retract pawl 159 into shaft 156. At the same time motor 140 stops so that tape drive ceases and motor 94 starts so that the next tape is moved into play position. A second tape drive motor (142), Fig. 2 (not shown) is provided to drive tape 32 in the opposite direction by means of a capstan (155a) and reel drive shaft (156a) associated with reel 30.
