Title: Myoelectric control circuit for artificial limbs
Inventor: ZYHLARZ GERHARD
IPC: A61F2/72
Filed: 1967-05-15
Abstract: 1,142,417. Control of D.C. motors. H. KOHLER, and H. MAY, [trading as VIENNATONE HORGERATE]. 15 May, 1967 [13 May, 1966], No. 22493/67. Heading H2J. In a myo-electric control circuit for a servoactuated artificial hand, terminals 1, 2 in channel I are connected to electrodes associated with the flexor muscles, whereas terminals 11, 2<SP>1</SP>, in a similar channel II are associated with the extensor muscles. The signals from the terminals 1, 2 are applied to a differential amplifier T1, T2, which is coupled to a further amplifier T3, T4, associated with transformer U<SP>11</SP>. Transistor T5 forms a final amplifier stage which is connected, through a voltage doubler circuit comprising diodes D1, D2, and capacitors C14, C16, to a trigger circuit T7, T8. If the useful signal amplified by diodes D1, D2, exceeds a threshold value determined by resistors R17- R21, transistor T8 becomes conductive to energize relay X which connects the driving motor for the artificial limb to a battery with the polarity corresponding to the desired direction of rotation. When channel I is operative, the driving stage of channel II may be shortcircuited by switch X1, so preventing false operation of reverse relay Y. Alternatively, a blocking voltage is applied to the trigger circuit in channel II when relay X is closed, so preventing operation of relay Y. The relays X, Y, may be replaced by transistors. The suppression of external interference signals is eased by reducing the frequency range of the differential amplifier T1, T2 by means of capacitors C1, C2, and C8-C11. Capacitors C17-C19 constitute filter elements for excluding voltages originating from the driving motor.

Abstract: 982,994. Automatic circuit-breakers. HEINEMANN ELECTRIC CO. June 21, 1961 [July 7, 1960], No. 22510/61. Heading H2B. In a multipole circuit-breaker unit similar to that of Specification 982,993, the intertripping member comprises an insulating cam 70 in each circuit-breaker, the cams being secured to a common shaft 71 extending through the circuit-breakers. When a circuit-breaker is tripped on overload, the toggle 35, 36 collapses and strikes the nose 75 of the associated cam 70. This turns the cam in a clockwise direction, causing the cam surfaces 74 of the cams in the other circuit-breakers to act on pins 85 secured between extensions 82 of the armatures 69. These armatures are turned by the cams to cause the tripping of the other circuit-breakers, the energy for this being provided by the mechanism of the overloaded circuit-breaker and not by its tripping device. In this arrangement the operating members 38 are interconnected by a rod 44 which is moved by the bifurcated end of an operating handle 47.
