Abstract: 738,844. Protective cut-out arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 20, 1954 [Jan. 21, 1953], No. 1779/53. Class 38 (5). In an impedance relay arrangement having operating and restraining circuit elements, one of which is energized in accordance with the difference between quantities derived from the current and the voltage of a protected circuit M, the said circuit element is connected as one arm of a bridge circuit which receives the current quantity at points which are equipotential with respect to the voltage quantity and receives the voltage quantity at points which are equipotential with respect to the current quantity. This permits independent adjustment of the quantities to determine the relay setting. In Fig. 1, the relay is arranged for response directly to impedance and has its restraining coil R connected as one arm of a simple Wheatstone bridge circuit to opposite pairs of points of which are applied the voltage from voltage transformer VT and the current from current transformer CT. The operating coil O of the relay is connected in series with the current transformer and bridge circuit. Rheostats A, B, C and ballast impedance Z<SP>1</SP> permit adjustment of the response characteristic of the relay. In Fig. 2 (not shown), the relay is arranged for response to the admittance of the protected circuit and has its operating coil connected as one arm of the bridge circuit and its restraining coil connected across the voltage transformer. In the first case the impedance response characteristic is a circle offset from the origin and in the second case the admittance response characteristic is a circle offset from the origin which when plotted in terms of impedance gives a straight line impedance characteristic. Both arrangements are directional and may be used in combination. A tuned circuit may be incorporated in the voltage supply to the relay.

Abstract: 1,144,739. Electro-sharpening. GILLETTE CO. Jan. 15, 1968 [Jan.17, 1967], No.2175/68. Heading C7B. A process of electro-sharpening, e. g. of razor blades, tools, knives, needles or electrical contacts, comprises making the object to be sharpened the anode in an electrolytic bath and positioning in said bath an electro-positive control electrode relative to the area of the object being sharpened so as to influence and control the current density in said area. The control electrode is preferably as electro-positive as the object to be sharpened, or more electro-positive than said object, e.g. by using a circuit in which connections from the positive pole of the source of current to the anode to be sharpened and the control electrode are separated by a variable resistor (8), Fig. 1 (not shown). The control electrode may be positioned parallel to the apex of the blade edge, e.g. at a distance of 0À01 - 0À05 inch therefrom, or elsewhere with relation to the blade to produce a desired shape of cutting edge. A holder for supporting a razor blade during said treatment is shown in which the blade is connected to the source of current by conductor 34 and the counter electrode 16 is positioned parallel to the blade edge supported between members 36, one of which serves to connect said electrode to the electric supply. For sharpening of points, e.g. needles or electrical contacts, the control electrode may comprise a small bared portion of a wire covered by a thick insulating portion. The control electrode may be of stainless steel or of platinum, and for sharpening a razor blade a circular stainless steel disc may be used.

Patent GB-1026676-A (GB)
Title: Vacuum deposition apparatus
IPC: C23C14/54
Filed: 1963-01-17
Abstract: In apparatus for the vacuum deposition of thin films of material from a heated crucible 16 on to a substrate 22, the rate of evaporation is monitered by signals obtained by the ionization of part of the vapour stream, the signals preferably being used to control the temperature of the crucible to keep the evaporation rate constant. The stream is passed through one of two ionization chambers 24, 26 through which a beam of electrons is directed from a self accelerating gun 27. Residual gas is ionized in both chambers but in chamber 26 the vapour stream is partly ionized also; the difference in ion currents in collectors 28, 30 is thus due to the vapour stream alone.  This difference is compared with a reference at 58 and any error is amplified at 52 to adjust the power supply to a filament 18 forming a cathode connected to a high voltage source 34, the other side of which is connected to the crucible forming an anode which is consequently heated. The electron stream from gun 27 is also stabilized in this case by controlling the power to filament 43 according to the difference between the voltage developed across a resistor 62 by the beam current and a reference 64. <PICT:1026676/C6-C7/1>
