Title: Brake
IPC: F16D51/18
Filed: 1961-01-03
Abstract: 899,846. Drum brakes. BENDIX CORPORATION. Jan. 3, 1961 [Jan. 4, 1960], No. 185/61. Class 103 (1). A pair of brake shoes 16, 18 is expanded into contact with a drum 12 by an actuator 26 between one pair of shoe ends 40 which abuts an anchor 42, a combined anchorage and forcetransmitting linkage 50 includes two interconnected levers 62, 64 and four spaced fixed fulcrums 54, 56, 58, 60 is disposed between the other pair of shoe ends 80, 82; the linkage being such that two of the fulcrums are used, according to the direction of drum rotation, to provide an applying force on one shoe substantially equal to the actuator applying force on the other shoe. The pistons 28, 30 of the double acting hydraulic actuator 26 act through links 32 on levers 34, pivoted on a torque plate 36, engaging adjuster screws 44 on the ends 40 of the shoes 16, 18. A portion of the torque plate 36 is laterally offset to provide an abutment having four fulcrum points 54, 56, 58, 60 about which the two levers 62, 64, joined at one end by articulated link 66, may pivot. The other ends of the levers are fastened through struts 76, 78 and manual star-wheel screw adjusters 84, 86 to the ends 80, 82 of the brake shoes. The dimensions L and M are designed such that their ratio is equal to the square root of the ratio of the actuator applying force to the anchoring force of the leading shoe. When the brake is applied with the drum rotating in the direction of the arrow, the actuator moves the leading end of shoe 18 into contact with the drum. The end 80 of the shoe anchors on the lever 62 which pivots about 54 and causes lever 64 to pivot about 58 to produce an applying force on the end 82 of the shoe 16 equal to the force applied by the actuator at the end 40 of shoe 18. As the force at the end 40 of the shoe 16 is of the order of three times that of the actuator 26, the end 40 abuts the fixed anchor 42, thus providing a two leading shoe brake substantially equal braking effort from each shoe. Under reverse rotation the actuator moves the end of shoe 16 and the levers 64, 62 pivot about 60, 56 to provide a similar movement.

Abstract: 945,365. Transistor circuits; pulse generators. BARRINGER RESEARCH Ltd. Jan. 6, 1960, No. 446/60. Headings H3P and H3T. [Also in Divisions G1 and G4] In a geophysical surveying system (see Division G1), the amplitude of D.C. pulses is sampled at predetermined times by means of a gate 49 comprising two transistor switches in cascade. The transistors 50, 51 are normally conductive, due to bias on terminal 56 controlled by a Zener diode 55, short-circuiting the signals arriving from a high-pass filter 48. When the amplitude is to be sampled a pulse is fed to terminal 54, cutting-off both transistors and allowing a pulse corresponding 'to the amplitude at that instant to be fed to amplifier 57, 62, tuned to the pulse repetition frequency. A sine wave at the pulse repetition frequency is thus provided by amplifier 62. A pulse of amplitude equal to that of the sine wave is provided by a gating circuit 66 operated by a pulse during the positive peak, as shown in Fig. 7. Pulse generators.-Figs. 17, 17a show a circuit for generating direct current pulses in an inductive loop 41. A bank of capacitors 40 is charged from the rectified output of transformer 42 via inductors 76 and discharged under control of thyratrons 38, 39. The timing of each pulse is controlled by a pair of blocking oscillators 32, 33 triggered by an input pulse at 34, 35, the output from each blocking oscillator being amplified by thyratron 36a, 37a having clipping diodes 36b, 37b. The main switch 88 controls the alternating supply to the heater transformers and to the supply unit 78 for circuits 32, 33, 36, 37. After a warming- up period controlled by relay 79, the ON button may be operated, energizing relay 82 which connects the alternating supply to the high voltage transformer 42. An over-current relay 84 is provided. Specification 883,465 is referred to.
