Title: Electric current moving coil measuring device with coil deflection stops
IPC: G01R1/36
Filed: 1961-04-05
Abstract: 939,741. Electric measuring instruments. E. H. GREIBACH. April 5, 1961 [April 5, 1960], No. 12233/61. Class 37. The speed of the moving coil 20 of a moving coil instrument under overload conditions is reduced so that the coil will not reach a spring coil stop at very high speed and be damaged due to shock when its movement is arrested. The external circuit 60 the current of which is to be measured is connected across portions 20.6, 20.7 of the coil only, and the coil 20 is shunted by a diode 61, the arrangement being such that under overload conditions the dynamically induced and generated voltages in the remaining coil part 20.5 due to the increasing current and to the movement of the coil respectively will exceed the threshold voltage of the diode 61 so that a current I 2  can flow in opposition to the overload current I 1  and generate a clamping torque opposing the deflecting torque of the moving coil. Diode circuit 61 will also carry some of the overload current, but since some of this current will also flow through the coil the latter will eventually impinge on the spring stops. In order to avoid excessive coil acceleration on the return movement when the overload is removed a further diode 62 is connected as shown, which, when the voltage generated in the coil 20 by this movement exceeds the threshold voltage will conduct and allow a dynamic braking current to flow. A " Universal shunt" changing resistance 64 tapped for different sensitivities is included in the circuit. Two or more diodes in parallel may be provided as shown. Instrument construction.-The coil 20 is suspended from pairs of metallic tensioned filaments 23, 24 and 25, 26, the ends of which are cemented into metal sleeves 27, 28. The latter is detachably fixed in aluminium saddles 31, 32. The coil stops 51, 52 are as shown. The meter coil may carry a mirror.

Title: Improvements in electrical systems of remote control
IPC: H02J13/00
Filed: 1940-07-31
Abstract: 541,061. Control systems for consumption apparatus. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. July 31, 1940, No. 12399. Drawings to Specification. [Class 38 (iv)] Switching control.-The load on a distributive system is limited to a maximum demand by a control station wherein the rates of consumption of a number of distributing substations are surmounted and the time integral of the aggregate compared continuously with the time integral of a standard rate of consumption. Each substation compares similarly, the time integral of its consumption with that of a standard rate of consumption. Overload relays in control and substations co-operate to cause the disconnection and subsequent reconnection of load on overloaded substations when the rate of consumption is excessive to a predetermined degree. Comparison is effected by multiposition switches stepped by impulse signals, impulsing at a rate proportional to the load, on meeting at KVAb meters at the substations and transmitted through impulsing relays by super-audio signal contacts of characteristic frequency over telephone channels to the control station. Two multiposition switches stepped, respectively, at the actual consumption and maximum steady consumption rates control a potentiometer whereby a potential proportional to the difference in their movements is applied, to a polarized overload relay. The potentiometer resistances may be arranged to vary the overload permitted in different portions of the demand period. Ripple frequency signals are transmitted to load disconnecting switches over the power mains by other multiposition relays for example as described in Specification 521,052, [Group XXXVII], operated by super-audio signal impulses transmitted by the overload responsive relay at the station and rendered effective on the load control switch as in a substation according to the position of the overload responsive relays in the control and substations.
