Abstract: 951,985. Recording-apparatus. CLEVITE CORPORATION. Nov.14, 1961 [Nov. 22, 1960], No. 40662/61. Heading G1J. [Also in Division H3] An electric recording system comprising a stylus electrode fed with a pulsating D. C. potential and connected in parallel with an inductive impedance selectively adjustable between high and low values so as to control whether the stylus records or not. A roll of paper 20 is fed past a recording stylus 16 connected to a source of D. C. pulses 10 through a resistor R1. A transformer winding W1 is connected between the electrode 16 and the base electrode 18 and has normally such a high impedance that the recording pulses are effective. When, however, a control potential at terminal 30 renders a transistor 24 conducting the impedance of the winding W1 becomes effectively very low so that the recording pulses are diverted and recording ceases. Transistor 24 may be supplied from a further transistor amplifier in which case for the same input signal the system will record when the first embodiment is not recording and vice versa, (Fig. 2, not shown). In a further embodiment two such systems are connected in parallel whereby when one records the other does not and vice versa so that the absence of a trace on either roll indicates a fault. The system is particularly applicable to monitoring the occurrence or duration of events.

Title: Reversible polarity ac to dc power supply
IPC: H02M7/162
Filed: 1966-09-12
Abstract: 1,112,799. Converting. GENERAL PRECISION SYSTEMS Inc. 12 Sept., 1966 [1 Feb., 1966], No. 40718/66. Heading H2F. A converter uses two thyristor bridge rectifiers 34, 36 to give D.C. of either polarity from a three phase A.C. input. Each bridge comprises three diodes and three thyristors. The output is proportional to a control signal, and as the control signal passes through zero there is an interval during which the bridge outputs overlap, both bridges giving brief output pulses 60 degrees apart. The control signal at input 16 is amplified in magnetic amplifier 18 and transistor circuits 22, 24, 26, 28. The firing circuits 30, 32 are powered by a square wave generator 40 which obtains square waves by clipping a sine wave with Zener diode. To make the " on " period of the square wave longer than its " off " period the sine wave is displaced by a bias. This provides the slight overlap in bridge outputs at and near zero input signal referred to above. Feedback signals from the load current may be applied to windings on the input stage magnetic amplifier and the firing circuit magnetic amplifiers.
