Filed: 1959-09-21
Abstract: 918,755. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 9, 1960 [Sept. 21, 1959], No. 32092/59. Class 37. In a semi-conductor device, such as one comprising a point or junction rectifying contact, a semi-conductor wafer is ohmically secured to a base made of like semi-conductor material by means of a thin layer of metal or alloy extending on the base beyond the periphery of the wafer, and having a terminal member in ohmic contact therewith. In an embodiment, a Si wafer is secured to a relatively more massive base of Si by means of a thin layer of Au deposited from vapour, or by melting in vacuo or an inert atmosphere, on the base, to cover an area greater than that of the wafer. The wafer, which may also be Au-coated, is brazed to the base, and is subsequently ground and/or chemically etched to the desired thickness, or to a wedge-shaped cross-section. The base may be fixed to a carrier body of metal. The layer of Au &c. may extend round the edge of the base and on to the surface of the base remote from the wafer, and may be used to braze the base to the carrier body, the terminal member being connected to the Au &c. layer on the edge of the base.

Title: Improvements in the synchronisation of similar three phase alternating current supplies
Inventor: MAINE ARTHUR EDWARD
IPC: H02P5/50
Filed: 1953-11-24
Abstract: 746,080. Synchronizing A.C. sources; automatic speed control systems. DE HAVILLAND PROPELLERS, Ltd. Feb. 18, 1955 [Nov. 24, 1953], No. 32584/53. Drawings to Specification. Class 38 (4). A system for synchronizing two three-phase sources comprises means for deriving from the sources a three-phase supply of beat frequency and the direction of phase rotation of which is dependent upon whether the frequency of the incoming or " slave " source is higher, or lower, than that of the running, or reference, source, the derived supply being amplified by a threephase transductor system and applied to a synchronous motor which varies the frequency of the incoming or slave source in a sense to bring it into agreement with that of the running or reference source. The transductoi system may comprise three transductors energized from an A.C. source and each controlled by one phase of the derived three-phase supply, the outputs from the transductors being rectified and interconnected to give the amplified threephase supply for operating the motor. The transductors may be suitably biased to afford a sinusoidal output waveform and the time constants of the transductor system may be so chosen as to give automatic protection upon excessive frequency difference between the two sources, say, due to failure of the reference source. The system is of particular application in the synchronization of the engines of a multi-engine aircraft, wherein each engine drives a three-phase tachometer generator, the synchronous motor acting on a constant-speed unit which controls engine speed by variation of propeller pitch.

Filed: 1962-08-24
Abstract: 1,024,121. Electric selective signalling. BOFORS A.B. Aug. 24, 1962 [Aug. 24, 1961], No. 32640/62. Heading G4H. [Also in Divisions Gl, G3 and H4] Each of two counters can be reset by the other or by pulses fed to the other for counting. Referring to Fig. 2, each of a succession of impulse periods contains a clock pulse B1 followed by a clock pulse B2. A data pulse A1 may be present in the period. First and second storage counters comprise magnetic cores 1 to 5 and 6 to 9 respectively, each counter being arranged as a shift register. Counting is performed by storing the pulse to be counted in the first core ( or 6) and shifting stored pulses along. Of the four windings shown on each core, the lowermost is used for shifting and the uppermost for resetting. Each data pulse A1 is counted by the first counter and resets the second counter. Each pulse B1 is counted by the second counter. All the types of pulses perform shifting functions as indicated by the winding connections. An output pulse BO from the last core 9 of the second counter resets the first counter. The first counter may produce an output pulse AO, from its last core 5. The data pulses A1 may be produced by a Geiger counter or radar system or be echo impulses in a proximity ignition system, the above arrangement enabling signals consistent with an acceptable radiation level or spurious signals to be discriminated against. A single-shot blocking oscillator may be included in front of the Fig. 2 system to discriminate against low-level signals and standardize (A1) pulse shape. Figs. 4-6 (not shown) show modifications which count not merely the number of impulse periods containing a data pulse but the number of data pulses. Figs. 7-8 (not shown) show an embodiment usable in a feedback system for controlling motor speed, in which pulses A1 and B1 are counted in first and second counters respectively, each A1 pulse also resetting the second counter and each B1 pulse also resetting the first counter. Figs. 9-10 (not shown) show a modification of the Fig. 2 embodiment having three counters for discovering in which of two channels (if either) pulses persistently occur before corresponding pulses in the other channel. Input pulses to either of the first two counters clear the third counter and the latter may produce clearing pulses for the other counters. This embodiment and a modification in Fig. 14 (not shown) may be used in direction finders. Use of the invention in direction-finding is the subject matter of Specification 1,024,122.
