A gas-filled high-voltage power cable constructed without a gasproof metal sheath comprises at least one conductor having a flexible effective surface of a smooth non-re-entrant form on which is built a dielectric wall of helical lappings of plastics film which is surrounded by a layer or layers of helically applied metal tapes which may be separated from the dielectric by an electrically conductive screening tape. In the embodiment described (Fig. 1) the cable has a stranded core 1 on which is wound a flexible screen 2 of conductive polyethylene. The dielectric comprises layers 3 of polyethylene tapes applied with a 10% overlap and surrounding these layers is a seamless envelope 4 of polyethylene. An outer screen 5 is constructed from a helically applied conductive polyethylene tape. The cable is reinforced against the gas pressure by two layers of aluminium tape followed by two layers of aluminium alloy tape 6. A tape of bituminized cotton 7 and a seamless P.V.C. tube 8 protect the cable from corrosion. Numerous examples of the types of core which could be used and of suitable reinforcing tapes are given. The seamless envelope 4 may be applied by extrusion or formed by heating the outer tapes so that they combine. The outer tube 8 may be of rubber. The gas used may be nitrogen or sulphur hexafluoride and the gas space may be increased by sprinkling the dielectric tapes with powdered glass or mica or by roughening the tape surfaces. A sealing end for the cable (Fig. 2) comprises an inner insulator 13 enclosed in a shedded insulator 18, the inner insulator 13 being filled with liquid at the gas pressure. Gas is supplied to the insulator by a pipe 19 and if this is metal it is connected to a similar insulator 19. A gas reservoir may be included to take account of expansion due to heating of the cable.

Abstract: 1329466 Keyboard CHERRY ELECTRICAL PRODUCTS CORP 9 Sept 1970 [1 June 1970] 43102/70 Heading G4H An electronic keyboard generates a binary coded output by stepping a counter at a point corresponding to the key depressed. The binary counter 16 is advanced cyclically by a multivibrator 11 feeding flip-flop 15 through NAND gate 14. The four least significant bits of the counter are monitored by a decoder 17 which produces an output on one of sixteen lines containing the key switches 24. The four most significant bits are monitored by units 18 to 20, one of which is activated by depressing key 19<SP>1</SP> or 20<SP>1</SP> or depressing neither. The units 18-20 select which group of characters the keys 24 will represent. When the counter reaches a position corresponding to which of the keys 24 and 19<SP>1</SP>, 20<SP>1</SP>, has been depressed the appropriate unit 18-20 produces an output at 18a say which inhibits NAND gate 14 and this stops the count. The inputs to gates 27 then represent the appropriate character. The monostable 12 holds gate 14 closed, after the depression of a character key, for a short period to eliminate the effects of contact bounce. Since the counter 16 is stopped by depression of a key, depression of a second key has no effect until the first is released. A pulsing strobe output may be obtained at 12c from monostable 12 for repeated generation of the same character code.
