Filed: 1923-05-01
Abstract: 220,033. Automatic Telephone Manufacturing Co., Ltd., (Automatic Electric Co.). May 1, 1923. Relays. -In a two-step electromagnetic relay provided with two coils wound on separate cores an armature is adapted to move about one fulcrum upon the energization of one coil and about another fulcrum upon the additional or separate energization of the other coil. The cores 61, 65, Fig. 2, of the coils 15, 16 respectively are secured by a screw 56 to an iron heel-piece 40 of which the upper end is bent at right angles as shown. The armature 42 is bent slightly as shown in Fig. 2, and carries at the bend arms 41, 50, Figs. 2 and 3 for actuating the contact springs, and is secured by screws 47, 53 to one end of a spring strip 46 secured at its other end by screws 45, 52 to the heel-piece 40. This strip is preferably of non-magnetic material to prevent sticking of the armature, and normally holds the armature against an adjustable back stop 43. When the coil 15 is energized the armature is attracted against the core 61 and the arms 41, 50 are moved sufficiently to cause the spring 19 to leave its resting contact without engaging its working contact and to cause the spring 18 to engage its working contact, the springs 17, 21 being unaffected by this movement. Upon the additional or separate energization of the coil 16 the armature 42 is further attracted and turns about a fulcrum located at the bend and the further movement of the arms 41, 50 causes the springs 17, 20 to leave their resting-contacts and the spring 19 to engage its working contact. In a modification a straight instead of a bent armature is used and the upper end of the heel-piece 40 is replaced by a vertically-adjustable bracket so inclined that the armature is normally closer to the core 61 than to the (core 65.

Abstract: 1,242,361. Feeding record tapes. INTERNATIONAL BUSINESS MACHINES CORP. 12 March, 1970 [9 April, 1969], No. 11797/70. Heading G5R. In a tape system in which a single capstan 15 drives the tape either forward from reel 11 to 10 or backward, if the tape has been stationary for a predetermined time, the sticking effect of the tape when it is to be driven in the backward direction is reduced by driving the tape first forward for a predetermined time or distance before reversing the drive. Assuming the tape has been stopped sufficiently long for timer 60 to feed out a signal indicating NEED HITCH, and the GO & BACKWARD signals are fed to AND gate 58, when the HITCH TIMER 55 is set, a further signal is fed to open gate 58 to cause a HITCH signal to operate through OR gate 53 the forward drive of capstan motor 22. This drive lasts for a time determined by timer 55 whereupon gate 58 closes to terminate the forward drive. While the HITCH signal is effective, AND gate 66 is closed, but upon its cessation a GO BACKWARD signal is fed to the drive circuit to reverse the motor 22. If the tape has not been stopped for a sufficient time for timer 60 to operate, gate 58 remains close and gate 66 operatas to allow backward operation. The timer 55 may be replaced by a counter fed with pulses from tachometer 25 to determine the distance moved forward before reversal of the drive.

Filed: 1969-03-07
Abstract: 1,219,393. Control of D.C. motors. WESTINGHOUSE ELECTRIC CORP. 7 March, 1969, No. 12208/69. Heading H2J. [Also in Division G3] In a system for limiting the rate of change of acceleration of a vehicle, a control signal is developed across a resistor 34 in the collector circuit of a transistor 35 with emitter current supplied from a constant D.C. source through an adjustable resistor 36. The collector circuit includes a capacitor 37 associated with rectifier 38, the voltage across the capacitor providing a modified signal which follows the control signal on line 33 but which is limited to a desired rate of change. The control signal is further modified by a load weight circuit 42 and is then applied to circuit 32 to be compared with the actual motor current which is represented by a signal derived through transductor 43. A chopper 14, which comprises main thyristor 15 with a commutating capacitor 16 and turn-off thyristor 17, is turned on and off to maintain the desired average current fed to traction motors M1-M4. The chopper is started by firing the thyristor 17 to charge capacitor 16, after which the thyristors 15, 18 are fired to energize the motors and to complete an oscillatory circuit through reactor 19 and thyristor 18 to capacitor 16. The chopper is turned off by firing thyristor 17 which applies the reverse voltage of capacitor 16 across thyristor 15. For dynamic braking, the motors are connected in two loop circuits having resistors 26, 27 in common, with the chopper 14 connected across the resistor 26. In another arrangement, the circuit for limiting the rate of change of acceleration comprises two transistors with their bases interconnected, resistors for independently adjusting the emitter currents, and a common collector circuit including the control signal source, the capacitor being connected in series across the collectors, Fig. 1 (not shown). In this circuit, different maximum rates of change are obtained for increase and decrease in the control signal.
