Abstract: 1,047,390. Circuit assemblies. UNITED AIRCRAFT CORPORATION. Dec. 24, 1963 [May 20, 1963], No. 50891/63. Heading H1R. An electronic sub-assembly comprises an insulating wafer 10 having on one or both sides thereof a plurality of terminal areas 12, conductive paths 16 extending between the terminal areas and covered with insulating material 18, and electronic components such as transistor 22 which have first electrodes connected to certain terminal areas 12, and conductors 26 which overlie the insulating material 18 connecting other electrodes of the components with other terminal areas 12. Conductive paths 16 may be of such length and composition as to form resistors. Conductive area 28 is deposited on insulating layer 18 to form a capacitor therewith and with the underlying conductor 16. Connection between circuitry on opposite sides of the wafer may be effected by means of conductive paths through, or around the edges of, the wafer. Further terminal areas (not shown) are provided on the peripheral edge of the wafer for connection of the sub-assembly in an electronic device. The wafer is preferably of a ceramic material, e.g. alumina and beryllia. The terminal areas are preferably applied by silk-screen printing moly-manganese followed by firing; these areas may be subsequently Ni-coated by electro- or electroless-plating. A thin conductive layer of Ta, Pt, Re, Nichrome (RTM) or, preferably, Cr is next deposited over the surfaces of the wafer by vacuum- or vapourdeposition or sputtering; then an insulating layer 18 of SiO 2  is deposited over the conductive layer. Discrete conductive paths 16 are formed by electron beam scribing through the insulating and conductive layers, and terminal areas 12 are exposed in the same way. The collector region of Si transistor 22 is connected to a terminal area 12 by alloying with the interposition of a Au or Au-Si preform 24, or by brazing, and the base and emitter regions are connected to other terminal areas by Au or A1 wires 26 which may be bonded to the transistor electrodes and to the terminal areas by electron-beam welding or thermocompression. The sub-assembly may finally be encapsulated.

Abstract: 1,227,215. Speech secrecy systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 20 June, 1968 [21 June, 1967], No. 29551/68. Heading H4R. In a speech scrambling device the incoming speech is converted to digital form, e.g. by p.c.m. or delta modulation, the resulting digits are ciphered and the ciphered digits converted back to an analogue signal for transmission. At the receiver the analogue signal is converted to digital form, the digital signal deciphered, and the original speech recovered from the deciphered digital signal by decoding. A synchronizing signal is transmitted with the scrambled speech to allow synchronization of the digita coding and decoding at the receiver with that at the transmitter, the synchronizing signal also being used for a.v.c. The synchronizing signal may be added before or after the conversion of the digital signal to analogue form at the transmitter and removed from the incoming signal at the receiver. A band of frequencies about the synchronizing frequency may be removed from the incoming signal at the transmitter. Two frequencies may be transmitted, the difference being used to provide the synchronizing signal in order to avoid the synchronizing signal being lost by frequency shift in a carrier transmission system.

Abstract: 1,257,243. Standby supply systems. DYNAMICS CORP. OF AMERICA. 3 Sept., 1969, No. 43524/69. Heading H2H.  A standby generating system wherein a generator 11 supplies a load 19 has the generator driven by a motor 13 connected to a supply 12 during normal operation and driven by a fuel-powered engine 15 when the supply 12 fails, the generator drive being maintained whilst the engine 15 is being started by the energy of a rotating flywheel 21. During normal operation the motor 13 drives a fixed stroke hydraulic pump 29 on the same shaft as the generator 11. The output of the pump 29 drives a variable stroke hydraulic motor 31 which motor drives the flywheel 21. During this part of the operation the stroke of the motor 31 is so arranged that the speed of the motor 31 and hence of the flywheel, is twice that of the pump, and hence of the generator. Should the supply 12 fail, the flywheel energy drives the motor 31 as a "pump", the output of which drives the pump 29 as a "motor" thereby to maintain the drive to the generator 11 whilst the engine 15 is being started. A sensor 27 responsive to the output frequency of the generator 11 provides a signal to a control means 33 which varies the stroke of the "pump" 31 as the flywheel loses speed so as to maintain the speed of the "motor" 29, and hence that of the generator 11, constant. A clutch 17 is provided between the motor 13 and the engine 15 whereby when the motor 13 is energized by the supply 12 the engine 15 remains stationary.
