Title: Power driven clutch and shifter assembly
IPC: F16D13/02
Filed: 1948-07-14
Abstract: 649,388. Operating clutches. DEHN. S. G. (Sunbeam Corporation). July 14, 1948, No. 18936. [Class 80(ii)] The shifter yoke 38 for the spring-loaded slidable member 31 of a cone clutch is clamped on one end of an auxiliary shaft 18 on the other end of which is rotatably carried a hub 70 on which a lever 66, provided with an operating cord, is adjustably clamped. The lever 66 is normally held in a predetermined position, determined by a step 74 on the hub 70 abutting against a stop 76 on the frame 11, by a spring 83, one end of which engages one of a number of notches 87 in a washer 63 fixed on the shaft end so as to enable the torsion to be varied, and may be turned to a second position determined by a stop 73 on the hub 70 engaging the stop 76. Spring-pressed pins 78 in the hub 70 co-act with ratchet teeth 81 on a cam disc 51 which is rotatablymounted on the shaft 18 and which has a cam face 52 co-acting with a cam face 55 on the frame. The lever 66 can thus rotate the cam 51 in one direction only, the pins 78 ratcheting over the teeth 81 in the other direction, and such rotation of the cam produces axial'movement of the shaft 18, and thus of the yoke 38, to cause engagement or disengaging of the clutch, The yoke 38 is guided by a rib 50 on the frame 11 and is acted on by a spring 46. Specification 557,222 is referred to.

IPC: H02M3/335
Filed: 1960-05-31
Abstract: 902,679. Converting; automatic voltage control systems. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 24, 1961 [May 31, 1960], No. 19304/60. Classes 38 (2) and 38 (4). [Also in Group XL (c)] A D.C. amplifier more particularly for use in providing a stabilized D.C. output voltage from a D.C. supply of lower voltage comprises means for modulating a D.C. input voltage, an A.C. amplifier for amplifying the resulting modulated signal, means for applying the A.C. output of the amplifier to drive the modulating means whereby the circuit oscillates and a non-phase sensitive rectifier connected to the output of the A.C. amplifier for producing a D.C. output voltage. The invention is described as applied to a circuit in which a stabilized 400 volt output voltage is derived from a low valued reference voltage. This reference voltage which constitutes the input signal from the amplifier is derived by a potentiometer RV1 from across a Zener diode Z 1 connected in series with a temperature compensating diode Z2, the diodes being fed with a constant current derived from a source comprising a transistor J1 and a further Zener diode Z3. The reference voltage is chopped by a chopper transistor J2 and the resulting A.C. voltage is amplified by a first negative feedback pair of transistors J3, J4 in cascade with a second pair of negative feedback transistors J5, J6. The resulting output across transistor T1 is fed to the input of a limiter transistor J7, the output of which feeds the chopper J2 so that the circuit oscillates, the frequency being determined by a series resonant circuit L1, C1 shunting the emitter load of transistor J4. The output from transformer T1 is also rectified in a voltage double circuit D1, D2 and a D.C. stabilizing feedback is applied from the output through resistor R1 to the input so that the input voltage is effectively the difference between the stable voltage and the feedback voltage. A capacitor C2 stabilizes the amplifier. It is stated that the transistor amplifier may be replaced by a valve amplifier and that the chopper may be replaced by a variable capacitor device or an electro-mechanical chopper. In the latter case the circuit may be arranged to oscillate at the mechanical resonance frequency of the electro-mechanical device.
