Title: Improved liquid pressure supply system
Inventor: TYLER STANLEY RALPH
IPC: F04D15/00
Filed: 1960-06-15
Abstract: 983,831. Centrifugal pumps; gas turbine jet propulsion plant. DOWTY FUEL SYSTEMS Ltd. June 6, 1961 [June 15, 1960(2)], Nos. 21055/60 and 21056/60. Headings F1C and F1J. [Also in Division G3]  A centrifugal pump 3 supplies fuel through a conduit 9, a metering orifice 43 and a port 47 to the afterburners of an aircraft gas turbine engine and its delivery is controlled by an inlet valve 7 actuated by a servo-piston 12 under the control of a valve 21 which is actuated by a diaphragm 26 subject to the pressure difference across the metering orifice so that the pressure difference is maintained constant. The degree of opening of the metering orifice is determined by a servo-piston 48 under the control of a valve 54 subject to the action of a feedback spring 58 and gas pressures in the engine applied to bellows 56, 57. Alternatively the valve 54 may be manually operated. To stop the flow of afterburning fuel an electrically operated pilot's control valve 69 is closed to cause depression of a servopiston 64 which interrupts communication between conduits 39, 41 and vents the conduit 41 and pump inlet to a port 73, thereby causing a second pump inlet valve 34 to be closed by a spring 38. The servo-piston 64 also vents the delivery conduit 9 of the pump through passages 61, 77, 79.

Filed: 1919-09-02
Abstract: 144,152. Western Electric Co., (Western Electric Co.). Sept. 2, 1919. Addition to 143,949. Simultaneous telegraphy and telephony; repeating and amplifying systems.- Telephone circuits used also for Morse signalling are provided with means by which an amplifying-repeater at an intermediate station can be brought into action from a terminal station, as described in the parent Specification, this being effected over a conductor which is also used for Morse signalling. Fig. 1 shows terminal stations A, C, and an intermediate station B with a cord-circuit containing a thermionic or microphonic repeater R. The two sides of the telephone circuits L1, L2 are used independently for Morse signals, interference being prevented by capacities and inductances arranged as shown. Direct signalling between stations A and U can be effected over circuit 3, 14, 12, 1, or over circuit 4, 15, 41, 13, 2, 16 if plugs P<1>9, P<1>5 have been inserted in jacks J9, J5. Signalling between stations A and B can be effected over circuit 4, 15, 20, and between B and C over 21, 13, 2, 16. The repeater R is under the control of a circuit 10, 11, which may, for example, be the heating- circuit of the thermionic valve filament. This circuit is closed by a relay 7 controlled by a key K; but the relay 7 may be put under the control of station C by inserting idle plugs P5, P2 in jacks J5, J2. These plugs disconnect the telegraph wires 21, 16 and connect a source of current 18 over the circuit 2, 13 to a relay 6, which open-circuits the relay 7; but when a plug P1 is inserted in jack J1 at station C, to extend a telephone connexion, a relay 5 de-energizes the relay 6 and the relay 7 becomes energized and completes the repeater circuit 10, 11. The repeater is also put in action by any failure of the circuit of the control relay 6. The disconnected telegraph wire 16 can be connected to another line through jack J,. A modification is described in which the repeater cut-out relay 6 can be controlled from either of the terminal stations A, C, and another modification in which repeaters at two intermediate stations can be controlled from a terminal station.

Filed: 1935-08-02
Abstract: 439,939. Cigarette-making machines. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MULLER & CO., 48, Zwickauerstrasse, Dresden, Germany. Aug. 2, 1935, No. 21980. Convention date, Aug. 16, 1934. [Class 130] In charging cigarette machines with cut tobacco, the delivery of the tobacco is initiated at regular intervals of time and maintained until a predetermined quantity has been delivered into the spreader of the machine. Tobacco to be fed to a spreader 2 of a cigarette-making machine 1 is drawn into a collecting tube 3 from a delivery table 7 by suction applied through pipes 10, 11 by an exhauster 12 when a spring- pressed hinged plate 14 is operated by a solenoid 25 controlled by a switch 23 in a relay 21. The relay 21 is in series with a switch 22 in a relay 20 which holds the switch closed as long as a switch 29 adjacent the collector 3, a manually controlled switch 30 and a switch 32 associated with the starting handle of the machine 1 are closed. The circuit of the relay 21 and switch 22 is completed at definite time intervals by contacts 17 which are closed by an electric clock 16, the relay 21 then closing the switch 23 and a 24 which short-circuits the contacts 17 to maintain the closure after these contacts have been opened and until the switch 29 is opened by an adjustable feeler 28 indicating that the collector 3 is sufficiently full. Opening the switch 23 cuts off the suction, a hinged gate 5 opens by gravity and the charge falls into the spreader 2. The time of charging may be reduced by opening the switch 30 or be increased by closing another manually operated switch 31 in parallel with the contacts 17. A second switch 19 operated by the relay 20 controls, in conjunction with the contacts 17, a signal light 18 and the switch 32 puts the device out of action when the machine 1 is not working.

Abstract: 1,169,266. Hydrofoil sailing boat. A. STEINBERG. 12 May, 1967 [1 June, 1966], No. 22052/67. Headings B7A, B7M and B7V. A hydrofoil 22, extending transversely beneath the hull 11 of a sailing boat having a mast 12, is fitted with a pair of ailerons 25 hingedly connected to the tail side, one on each side of the longitudinal centre line of the boat, and the ailerons are linked by mechanical means and a control mechanism to the shrouds 17, connected at their upper ends 18 to the mast 12, in such a manner that when the transverse wind force on the boat changes one aileron is raised and the other is lowered so that the boat remains transversely balanced. At the beginning of the operation to get the boat riding on its hydrofoil ailerons 25 are horizontally aligned and are pushed downward by the action of springs 41 on shaft 39 in which position the ailerons increase the lift. As the boat picks up speed and rides upon the hydrofoil the force of the wind upon the sail will cause the mast to shift away from the wind. This movement of the top of the mast causes the belt 47 to rotate control drum 35 thus forcing one of the rods 37 downwards and pulling the other one upwards. One aileron is thereby lowered and the other raised a sufficient amount to counterbalance the force of the wind and to stabilize the boat so that it may sail at high speed upon the hydrofoil. Fig. 4 shows a further rear hydrofoil assembly 27 mounted below the stern end of the boat and having a centre support 28 to which the rudder 29 is hingedly connected. Ailerons may be included in this rear assembly.
