Title: Improvements in and relating to electric switches
IPC: H01H1/60
Filed: 1926-04-29
Abstract: 251,643. British Thomson-Houston Co., Ltd., (Assignees of Hilliard, J. D.). April 30, 1925, [Convention date]. High - potential switches; pneumaticactuation.-Oil switches have the relatively fixed contact member 9 insulated from the metal containing casing 4 the movable contact rod 13 being in connection with the casing 4. The casing is supported by suspension insulators 2 from a structure 1 and has a detachable bottom plate carrying an inner removable plate 15 which supports an oil-tight bushing 16 through which the contact rod 13 passes into the oil chamber. An annular spring contact 24 surrounds the rod and maintains good electrical contact between it and the casing 4 to which is bolted the outgoing lead 14. In order that the contact rod may be removed without emptying the oil casing a cap 17 is secured to the inner face of the bottom plate having a central hole through which the contact normally passes but which may be closed tightly by a hinged door 20 operated from outside through worm-gearing by a rotary handle 21. For moving the contact member 13 its lower end carries a piston 28 working in a cylinder 27 the piston being operated by compressed air controlled by a slide valve 40 which is moved into position by a rod 41 containing an insulating section 42. The cylinder 27 is supported beneath the oil casing by a metal stool 26 bolted to its bottom plate. The oil chamber 4 may be provided with an inner shell 5 giving an expansion space 6 between the two casings and a relief valve 8 for the arc gases is provided. Alternatively, an air space above the oil may be provided. Specifications 13852/02 and 190,346 are referred to.

Title: Improvements in or relating to Teleprinter Systems
IPC: H04L9/18
Filed: 1967-03-10
Abstract: 1,170,655. Telegraphy. SIEMENS A.G. 10 March, 1967 [11 March, 1966], No. 11352/67. Heading H4P. In a teleprinter system comprising two subscribers in half-duplex connection, each subscriber has a unit as shown in which the transmission side is blocked during reception and vice versa. Serial data from the transmitter sk passes via gate SGO to unit EO where it is converted to parallel form. The data may be ciphered at VI, and is serialized at SL from which it passes to line. When a signal is to be transmitted, bi-stable SS is set. This sets unit MVS which indicates the present operating state. When unit EO has cycled once, SS is reset and unit SL is started. When SL has cycled once a pulse passes via delay S and gate GS, now enabled since SS is reset, to reset MVS. When set, unit MVS inhibits receiving gate SGL so that no signals can be received from the line for about one character time longer than the duration of the input from sk. A similar circuit on the receiving side, feeding teleprinter EM, blocks the transmission side during reception. In the case of synchronous working gate SGS is inhibited when the transmitter sk is providing filler signals. When signals are to be ciphered or deciphered by units VI, VII, unit MVH causes gates SGO and SGL to be blocked during the transmission of a " start of enciphering " signal.

Abstract: 578,588. Electron oscillators ; cathode-ray tubes. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 14, 1942, No. 11386. Convention date, Aug. 20, 1941. [Class 39 (i)] A high-frequency oscillator comprises an output resonator 11 excited by a density modulated electron beam which passes through its grids 13, 14 to a collector electrode 27, density modulation of the beam being effected by the combined action of a magnetic field between the poles P, P of a magnet M and an exciter resonator 10 through which electrons from a gun 19, 17 are projected, the magnetic field causing the electrons to follow a curved path from the exciter resonator 10 to the output resonator, through a crescent-shaped tube 15 which connects the two resonators. The unmodulated electron beam from the gun is oscillated about its central path C by the high-frequency electric field set up between the central portions 25 of the resonator 10 so that electrons reach .the resonator 11 by paths such as D, E of different lengths, the arrangement being such that groups of electrons in different paths come into phase at the grids of the output resonator. The resonator 10 is excited from the resonator 11 by a coupling loop 23, 24.

Abstract: 514,170. Cathode-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd., and MYNALL, D. J. April 27, 1938, No. 12643. [Class 39 (i)] The magnetic deflecting field for cathode-ray tubes is produced by a magnetic ring carrying at least one pair of coils adapted when energized to produce parallel lines of force within the ring, and the number of ampere turns per unit of circumference of the ring is made different for different portions of the circumference, and is adjusted to produce parallelism of the lines of force. In one form, as shown, the ring 1 carries two windings 2, 3 disposed diametrically opposite one another and having stepped ends 4. A second pair of coils may occupy the spaces between the first to produce a deflecting field at right angles to the first, and the coils may be stepped to fit into the stepped ends of the first pair of coils. In an alternative form, the ring may be wound with two interlaced toroidal windings, and the graded ampere turn effect is obtained by cross-connecting and open circuiting certain portions of the two windings. The magnetic ring may be formed of a stack of thin, radially narrow punchings, or of a helix of wire or a powdered iron moulding. It may have a thin sheath of insulation, and have an additional conducting sheath of copper or aluminium either inside or outside the windings.
