Filed: 1954-05-27
Abstract: 783,426. Coating cores by extrusion. ENFIELD CABLES, Ltd. May 27, 1955 [May 27, 1954], No. 15716/54. Class 87(2). An electric cable or a pipe or hose is covered with a protective sheath of insulating or similar material by passing it through an extrusion machine comprising a number of feed screws which turn about stationary axes which are disposed symmetrically about and parallel to the path of travel of the cable &c. through the machine. As shown, four feed screws 31 rotate within nitrided nitralloy barrels 33, the screws surrounding joined central tubes 67, 65 through which a cable to be coated is fed. The four screws are driven by gears 90 through the medium of rotatable sleeves 92, 95. Each screw is 3¢ ins. in diameter and sixteen times as long, and its root diameter increases to give the material a compression of 2¢ : 1 as it passes through the'screw barrel. Each screw has its own hopper 36. The four screws deliver the material to outlets 34 and thence to four passages 48, one passage for each screw, these passages being formed between an inner conical tube 47 and an outer conical housing 46. Each passage has side walls 48a which diverge, and the passages converge, meeting at knife edges 49. The cross-section of each passage progressively decreases in the direction of feed, so that the pressure of the material gradually increases. The material emerging from the passages traverses a short annular passage 50, then goes through a ring-shaped strainer 51 and finally passes between the tube 47 and an outer conical tube 53 and so on to the cable. The tube 53 terminates in a ring 61 which determines the thickness of the coating applied to the cable. Tube 47 terminates in a ring 60. The conical faces of these two rings converge towards their outlet. The rings may be replaced by other rings, Fig. 5 (not shown) for use with smaller cables. The tube 53 may be adjusted by means of bolts 54. Housing 46 may be swung out about a pivot 75, after removal of bolts 74. The tubes 65, 67 may be heated, to heat the cable. The tube 67 may be connected to a source of vacuum to pull the material down uniformly onto the cable, or to air pressure when hoses are being made.

Title: Process for the production of oxide cathodes by spraying
IPC: H01J9/04
Filed: 1936-06-05
Abstract: 476,385. Thermionic cathodes. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. June 5, 1936, No. 15794. Convention date, June 5, 1935. [Class 39 (i)] In producing cathodes by spraying on to a metal core compounds subsequently converted to oxides, a coating which quickly solidifies is first sprayed on and this is then covered with a wet coating which forms a smooth surface and which is subsequently dried in a furnace or current of gas above room temperature but below 200‹ C., preferably at 60-90‹ C. Carbonates of barium, strontium and calcium in specified proportions are introduced into a solution of nitrocellulose in amyl acetate and acetone and are sprayed on to a core, such as a small nickel tube forming an indirectly heated cathode, by a pistol adjusted so that the coating solidifies at once. A similar composition is then sprayed on by a pistol adjusted so that a wet coating filling the cavities in the first coating is produced. This coating is dried at 80-100‹ C. and the cathode is then mounted in the discharge tube and heated to 1000‹ C. during the evacuation to convert the carbonates to oxides prior to activating the oxides. The Specification as open to inspection under Sect. 91 comprises also modified processes in which the first step of applying a quickly solidifying coating is omitted and in which a nickel wire cleaned with carbon tetrachloride and mounted on the stem of the discharge tube has the coating sprayed on at an acute angle longitudinally of the wire. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to radio transmission systems employing pulse modulation
IPC: C07K1/00
Filed: 1939-05-30
Abstract: 529,984. Duplex, multiplex 'and secret systems. KOLSTER-BRANDES, Ltd., and BEATTY, W. A. May 30, 1939, No. 15921. Drawings to Specification. [Class 40 (v)] In a wireless system in which the modulating signals comprise a train of pulses representing the variable edges of a series of pulses varied in duration in accordance with the amplitude of a sound or other signal wave as described in Specification 523,575, the complementary fixed edge or marking pulses required by the receiver to reproduce the original wave are separately transmitted on a different carrier frequency. In a multiplex system employing pulse modulation, all channels use the same pulse frequency; the pulse generators and receivers of the various channels are synchronized by the marking pulse transmitter, or the pulse generators may employ a common saw-toothed wave. The synchronizing pulses for the transmitters may be transmitted over wires in basic form or as a modulated carrier. In a two-way system, the marking pulses in one direction synchronize the pulse generator for the opposite direction of transmission. The marking pulses may also be time modulated to provide an additional channel, the fixed edges of such pulses being utilized at the receivers of other channels to derive synchronizing pulses. Further secrecy may be ensured by variation of the carrier frequencies. When the system includes television, the pulse generators may be synchronized by television synchronizing pulses. Specifications 524,671 and 527,904 also are referred to.

Title: Mechanically regulated multi-stage combustion chambers for aircraft jet engines, pulse-jets or gas turbines
IPC: F23R3/26
Filed: 1955-08-03
Abstract: 822,328. Gas turbine plant; jet propulsion plant. SCHMIDT, F. A. F. Aug. 3, 1955, No. 16019/55. Class 110 (3). [Also in Group XII] A gas turbine or pulse jet unit has primary and secondary combustion chambers having inlet openings respectively for primary and secondary air or gas, a transfer opening leading from the primary to the secondary combustion chamber which discharges through an outlet opening into a propulsion nozzle or turbine and rotating disc type valve members to control the inlet openings, the transfer opening and the discharge opening. After scavenging of the primary part 4 of the combustion chambers with precompressed air, the inlet and outlet openings are closed by the rotating discs 1, 2. Fuel is then injected through the nozzle 8 and ignited by one or more sparking-plugs 9. The outlet opening is then opened by the disc 2 and the combustion gases flow into the then closed secondary part 6. The valve member 3 then allows the gases to flow to the propulsion nozzle or turbine. As the result of the inertia of the gas flowing from the primary part 4 to the secondary part 6 the pressure in the primary part 4 falls below atmospheric so that the primary part can be opened for scavenging before the secondary part. Driving of the valve discs is preferably effected from the rotor shaft but the valve discs 2, 3 may be driven by the action of the gases on blades on the valve discs. The valve discs may be hollow and cooled by air which passes into the gas stream or may be cooled by water. A diagram showing the relative opening and closing of the valves is also described. As shown, the primary and secondary parts are arranged radially with respect to one another. To facilitate the design of the valve disc 1 the secondary part may be displaced slightly in a circumferential direction. The combustion may take place wholly or only partially in the primary part.

Filed: 1922-06-09
Abstract: 202,771. Field, A. B., and Metropolitan-Vickers Electrical Co., Ltd. June 9, 1922. Dynamos and motors combined for transmitting power.-A ship propulsion system consists of a synchronous generator A, Fig. 1 supplying current to one winding of a propulsion motor 3 and an asynchronous or synchronous generator B supplying the other winding of the motor 3 during full-speed operation. At cruising speed the motor 3 is run as an induction motor, its secondary circuit being completed through a resistance 7. The generators A and B are provided with direct current field-windings and are adapted to operate short transition periods as induction generators. Variations in the cruising speed may be effected by varying the feed of the prime-mover 1 of the generator A. Small variations in speed, when both generators A and B are operative, are obtained by controlling the speeds of either or both of the generators. When four motors and three generators are employed, each generator A, Fig. 2, supplies one winding of two motors, and the other windings of the motors are supplied from the generator B. In a modification, one winding of each of a pair of motors is supplied from one generator A and the other windings of the motors are supplied from a second generator B driven by the same prime-mover as the generator A. In a further modification the generators A and B are independently driven.
