Abstract: 610,654. Switching carrier frequencies. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946, No. 11332. Convention date, Nov. 25, 1944. [Class 40 (v)] A single high-frequency line is switched in sequence to a number of lines by one or more rotary blades moving in succession past a number of sector-shaped stator plates, the length of the adjacent surfaces of rotor and stator when in coupling relation being equal to half a wavelength at the mean frequency of the operating band. As shown, a rotary blade 27 connected to the single H.F. line moves past the sector-shaped stator plates 17 ... 20 in succession, the latter being connected to the plugs 9 ... 12 for receiving four separate feed lines. Both rotor and stator may comprise a number of superposed plates which interleave during the rotation of the blade 27 by the shaft 38; and the total radial length of the gap between adjacent surfaces is a half wavelength. Diagonal screens 22 ... 25, cut away to allow the rotor to pass, prevent interaction between the stators. Three other rotor blades 28 ... 30 connected to the earthed casing may be provided. The stators may be so arranged in relation to the casing that where they are widest the gap between them and the casing is increased, so that the surge impedance along the opposing surfaces is substantially constant, Fig. 3 (not shown). The switch may be used to couple a plurality of aerials in sequence to a direction-finding receiver.

Abstract: 220,029. Robinson, J., and Joyce, G. J. R. May 1, 1923. Directive signalling. -The precise point of minimum reception in a frame aerial is determined by causing a normally - paralyzed valve to be rendered active at the critical moment. In the twocoil system shown, a potentiometer 7 in the plate circuit of a control valve 5 associated with the " minimum " coil 1 is connected across the grid and filament of the main valve 9 in conjunction with the " maximum " coil 2, the variable point of the potentiometer being so set that the applied grid voltage is sufficient to paralyze the valve 9 except when minimum current flows in the coil 1. At this critical position, the characteristic signal of the transmitting station is received at maxi. mum strength from the coil 2. One coil may be used alone, in conjunction with a local highfrequency oscillator the main valve being rendered inoperative by the applied bias except at the critical position of minimum reception. Instead of using a telephone receiver, the required position may be indicated by the lighting of a signal lamp.

Title: Production of a supply of heated gases from gases containing catalytically combustible constituents
IPC: F02C6/14
Filed: 1959-04-08
Abstract: 922,177. Gas turbine plant. SCIENTIFIC DESIGN CO. Inc. April 8, 1959 [May 29, 1958], No. 11903/59. Class 110 (3). [Also in Group XIII] A gas mixture containing combustible material is catalytically oxidized in a reactor 3 and the resulting vapour, e.g. ethylene oxide, passes from a compressor 5 to a scrubber 8. The purge gases pass through a line 10 to a catalytic combustion vessel 16 after by-passing or passing through a further reactor 11 and scrubber 13. In the vessel 16 they pass down, Fig. 2 (not shown), through a catalytic oxidation zone, an open-brickwork zone and then a zone of heatstorage solids (see Group XIII) which may be iron or steel balls or alloys, ceramics, stone or pumice. The oxidation zone may be by-passed by a pipe 20. The gases leaving the vessel 16 are expanded in a turbine 6 to supply the power for driving the compressor 5. The desired products from the scrubbers are collected in a line 9 for passing to a stripping column. The heat-storage solids prevent sudden temperature changes in the gases from being transmitted to the turbine 6. They may be used, too, if the vessel 16 is charged with gases from fired gas heaters.
