Title: Improvements in or connected with radio-navigational apparatus and the like
IPC: G01S1/02
Filed: 1920-03-19
Abstract: 163,855. Murray, J. Erskine-, and Robinson, J. March 19, 1920. Bearings, determining; directive modulating systems and apparatus. - In wireless directional transmitting systems, means are controlled by a rotary aerial for emitting successively, along various compass bearings, waves having a different frequency for each direction of propagation. Fig. 1 shows the application to a spark system. The rheostat 13 in the field 12 of a motor 11, driving an alternator 10 on the same shaft, has a rotating contact arm 14 on the shaft 5 of the directional loop aerial 4. An impedance 15 with arm 22 also rotated with the aerial 4 maintains resonance of the low-frequency circuit 9, 10, 15 at the varying speeds. In the application to a continuous-wave system, Fig. 2, an interrupter 19 in the grid circuit of the valve 18 rotates with the aerial spindle 5 driven by the motor 17, the field of which contains the variable rheostat 20 with rotating arm 21. Tonic train is produced by the interrupter, the frequency of which varies with the direction of the aerial. In a third application, a high-frequency oscillating valve has a modulating valve oscillating at low frequency, such low frequency being determined by a condenser of which the capacity is varied by the rotary aerial.

IPC: H02K3/42
Filed: 1927-03-25
Abstract: 268,371. Allgemeine Elektricitõts- Ges. March 25, 1926, [Convention date]. Cores; yokes.-To reduce eddy current losses in heavy end face constructional parts of polyphase motors, magnetic bodies laminated in the peripheral direction are provided to form a highly conductive path for the rotating stray flux. As shown, the magnetic body consists of a ring d of spirally wound flat bands located between the end windings c and the end plate b which it is desired to protect. The bands are secured by radial rivets or screws f preferably insulated, and the ring as a whole is carried by the pins h which support the end turns. Alternatively, the bands may be welded together at a number of points on the side remote from the end windings, or clamps, which in addition secure the ring on the end plate, may be employed. The rings may consist of concentric bands or of a number of laminated arc-shaped segments, or a polygonal body made up of a number of straight laminated bridges may be used. Spaces may be left in the magnetic bodies to weaken the stray flux. Stray flux conducting paths may be provided also upon the inner faces of the machine covers.

Abstract: 787,519. Liquid collecting-devices for dynamoelectric machines. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 16, 1956 [March 30, 1955], No. 8357/56. Class 35.  A homopolar generator comprises a shaft 1 driven by pulley 2 and field windings 3, 4, cooperating with armatures 5, 8, which are insulated one from the other. The brushes of the machine comprise annular members 13 mounted on the shaft and fixed together by bolts 41 which apply them against sleeve 14. Fixed annular elements 16, 17 surround the members 13 so as to provide a gap 15 sufficient for the passage of mercury or other conductive liquids. Each element 16 has a groove 19 which is filled with liquid when the machine is to be started, an edge 20 projecting into groove 21 in the member 13 preventing leakage of liquid along the shaft. Liquid is fed into the gaps 15 through conduits 23 and passages 22 in the upper elements 17, and also through conduits 25 and passages 24 opening into grooves 19. The outflow of liquid from the gaps takes place through spaces 26 and conduits 27. Externally of the machine, the conduits 23, 25, 27 are connected with a heat-exchanger for cooling the liquid and with valves for adjusting the flow-rate as well as with flow meters. Current is collected from the brushes by means of bars 31, 32 connected to a squirrel cage 33. The chambers 11, 12 are gas-tight and filled with nitrogen, the windings 3, 4 being separately housed and cooled by forced draught. The liquid-conduits are emptied when the machine is not in use, means being provided for filling the liquid-circuit quickly upon starting the machine. For this purpose a tank is provided at the lower part of the machine and the liquid is drained into this tank by opening a valve and placing the tank under atmospheric pressure, Fig. 2 (not shown). To fill the liquid-circuit, nitrogen under pressure is supplied to the tank so that the liquid rises into conduits 23, 25 and tends to fill gap 19. If the machine is then started, the liquid is gradually projected by centrifugal action through the conduit 27 so that the whole circuit is eventually filled with liquid and circulation takes place through the heat-exchanger with the circuit cut off from the tank.

Title: Improvements in or relating to electrically-operated remote control apparatus
IPC: G01G3/12
Filed: 1944-05-04
Abstract: 585,091. Electric control systems. MESSIER AIRCRAFT EQUIPMENT, Ltd., and NEILSON, C. B. V. May 4, 1944, No. 8465. [Class 40 (1)] In a positional control system employing a pair of potentiometers P1, P2 connected in a D.C. bridge circuit, the unbalance current modulates an A.C. supply and through an electronic relay controls a servomotor to restore balance. If the contact of potentiometer P1 is moved so that it becomes positive with respect to that of potentiometer P2, rectifiers W1, W2 are conducting and the output is stepped up and applied through a voltage doubler circuit C1, W5, to an electronic relay V1, ionisation of which operates an electromagnetic relay A and causes the motor M to drive the contact of potentiometer P2 in the appropriate direction. If the contact of P1 is moved in the opposite direction, rectifiers W3, W4, are conducting.and an electronic relay V2 is ionised so that a relay B causes the motor to drive-in the reverse direction. In order to increase the sensitivity of the system, the resistance elements of the potentiometers may be made of a material having a negative current-resistance characteristic.

Abstract: 1,248,509. Heating gases. C. A. JENSEN and L. L. WOOD. 18 Feb., 1969 [19 Feb., 1968 ; 27 Jan., 1969], No. 8704/69. Heading F4S. [Also in Division G6] A hot gas is heated by subjecting it to radiant heat. To facilitate the absorption of the radiant energy, gas is rendered more opaque to thermal radiation by introducing an ionized material, for example the alkali metal cesium. The thermal radiation is derived from a nuclear reactor in the form of an annular furnace rotatable about the heating zone. Hydrogen gas passed through such a reactor may be used for rocket propulsion or fed through an M.H.D. generator. The reactor fuel material is maintained at its melting point and is held on the inner surface of the rotating containment cylinder, by centrifugal forces, the gas heating zone being formed along the cylinder axis. In an alternative form, heating of the gas is effected by a liquid material in a rotating tube in which the liquid is heated by an electric current.

Abstract: 1,145,412. Coating cores by extrusion. INTERNATIONAL STANDARD ELECTRIC CORP. 22 Feb., 1968 [24 Feb., 1967], No. 8748/68. Heading B5A. In the extrusion coating of a cable or conductor with rubber or thermosetting resin, the core is coated by an extruder 4, and the coated core is drawn through a vertical tube 5, a curved tube 8 and a substantially horizontal tube 7, the composite tube containing steam under pressure above level 6 to form a vulcanization zone and water under pressure below this level to form a cooling zone. The core is drawn initially from a spool 1, around sheave 2 and capstan 3, and the coated core is hauled off by a capstan or, as shown, caterpillars 9 to a takeup spool 10. Angle 11 is preferably in the range 75-105 degrees and the inner surface of curved tube 8 is made sufficiently smooth so that internal guide means are unnecessary. The above arrangement allows a relatively short length of vertical tube 5, e.g. one-fifth of the length, to be used for cooling.
