Filed: 1973-12-06
Abstract: 1421353 Testing components STANDARD TELEPHONES & CABLES Ltd 6 Dec 1973 56522/73 Heading G1U Electrical components are tested by applying a voltage or current having a fixed rate of change, starting a counter at the start of the application and stopping the counter when the component is sensed to have failed. Ten capacitors 101 are individually connected to failure sensing latches 106, Fig. 2 (not shown), which in turn will stop counters 108 when the capacitors fail. The voltage across the capacitors is increased under the control of a stepping motor 104 driving a potentiometer in D.C. Ramp 103, Fig. 3 (not shown). The potentiometer output is smoothed to provide a near straight line. The motor 104 is driven from a variable frequency multi-vibrator 109, Fig. 4 (not shown) which also drives the counters 108. The frequency is variable in association with the voltage range of the ramp 103.

Abstract: 752,504. Electrical measuring instruments. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 27, 1954 [May 30, 1953], No. 15733/54. Class 37. A moving coil for an electrical measuring instrument has coil turns consisting of lines of conductive deposit on a former or carrier. The invention provides tensionstrip suspended lightweight coils for sensing very weak currents, i.e. fractions of a microampere. The required deposits may be produced by a photographic process which comprises coating the chosen carrier (e.g. of glass or cellulose acetate) with suitable light - sensitive material and (1) forming a spiral coil on an annular carrier, Fig. 1, by optical projection of the required spiral configuration from a highly magnified image; or (2) forming a helical coil edgewise on a rectangular carrier, Fig. 2, by using a helically scanning light beam; in this process the carrier rotates about its axis at right angles to the plane of the coil and also moves along this axis in relation to a stationary light beam. In a detailed embodiment a glass plate coated with bichromate in albumin receives a spiral configuration by optical projection of a spiral drawn on a sheet of white drawing paper, the outer turn of this drawn spiral having a diameter of about 50 cm. and this is reduced in the projected image to about 10 mm. The unexposed parts are removed and a silver layer is applied by vaporization to the free glass surface and reinforced by electro-plating. The rear side of the glass plate is also coated with silver and forms a mirror surface so that the moving coil may be used in a mirror oscillograph.
