Title: Logic circuitry
IPC: H03K19/084
Filed: 1966-01-04
Abstract: 1,091,032. Logic circuits. RADIO CORPORATION OF AMERICA. Jan. 4, 1966 [Jan. 19, 1965], No. 290/66. Heading H3T. A logic circuit comprises two or more identical units X, Y, each having two or more inputs A, B acting on a level control circuit Q1 to give outputs to control the conduction of active elements Q2, Q3 which in turn provide a logic output at E 0 , and inhibitory connections 15, 15<SP>1</SP> from one unit to the others. Considering unit X on its own, if either A or B is +0À1V the corresponding diode will conduct and turn off Q1 and hence Q2 also. Q3 will conduct to charge up the capacitance C 0  of the load connected to E 0 , the voltage at E 0  levelling off at +4À3V. If both A and B are +4À3V Q1 turns on and saturates, turning on Q2 and dropping the E 0  voltage to + 0À1V. The circuit thus provides a NAND function if high-level signals are regarded as significant " 1 " or a NOR function if low-level signals are significant. D3 is a fastrecovery diode and serves to protect against noise voltages and to turn off Q1 rapidly. If one of the inputs A<SP>1</SP> or B<SP>1</SP> to unit Y is +0À1V when both A and B are +4À3V, a large current would flow through Q2 and Q3<SP>1</SP>. This is prevented by the connection between the bases of Q3 and Q3<SP>1</SP>, this ensuring that when the conduction of Q3 falls due to the saturation of Q1, the emitter current of Q3<SP>1</SP> will also be reduced. The potential of point 16 will fall whenever one of the transistors Q1 is turned on, thus reducing the current through all the transistors Q3, Q3<SP>1</SP> .... Transistors Q3 may be replaced by networks having several active elements. PNP transistors can be used instead of NPN.

Title: Improvements in or relating to protective control systems for electric motors
IPC: H02H3/16
Filed: 1946-04-27
Abstract: 605,932. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. April 27, 1946, No. 369/48. Divided out of 605,927. [Class 38 (v)] In an earth leakage protection system for polyphase apparatus having an un-earthed neutral, a neutral point inductance is used to enable the fault current to operate a leakage relay. In the circuit shown, a motor B is controlled by a circuit-breaker C, the operating coil C4 of which is energized by a gas-filled triode J when a switch D is closed, in the manner described in Specification 568,336. A leakage relay S has its coil S<1> connected between the biassing system of the triode and a neutral point inductance A. When a balanced or unbalanced fault occurs as indicated at 12a ... 12c, a circuit is completed from the coil S1 through the inductance A, the fault path, earth, through switch D, inductance P, connection Y, and through line Z and resistance K to the coil. Contacts S2 close to shortcircuit the bias resistance K and inductance P and switch D, to increase the bias voltage, so that triode J ceases to fire, coil C4 is no longer energized and the circuit-breaker opens. The contacts S2 now open, but whilst the fault remains, the opening and reclosing of switch D will not effect the closing of the circuitbreaker C, as a parallel path still exists through the relay coil S1; inductance A and the fault path, which short-circuits the bias resistance K and prevents the triode from firing. A faultindicating flag S7 is operated by the relay S and is latched by S4, but is reset by a striker S5 when the circuit-breaker is reclosed after the removal of the fault. The neutral of the supply may be earthed as shown, through a limiting resistance G and a half wave rectifier H which permits the operation of the triode to be unaffected by this earth during the positive half-cycles.
