Inventor: PATON BORIS EUGENIEVITCH
IPC: B23K25/00
Filed: 1959-02-09
Abstract: 918,070. Welding by fusion. INSTITUTE ELECTROSVARKI IM E.O. PATON. Feb. 9, 1959, No. 4403/59. Class 83 (4). In electro-slag welding the maximum slag temperature is lower than the slag boiling point but is higher than the melting point of the metal being welded. In a machine for welding a vertical seam, electrode guides 6, Fig. 1, and feeding devices, melt retaining plates 5 and a flux hopper 7 having a valve 7a linked to the feeding devices are mounted on a carriage 2 moving along a vertical stand 11. The electrode guides 6 are reciprocated horizontally. Upward movement of the carriage 2 is automatically controlled in accordance with the level of the molten metal 10 as sensed by a member 9 on one of the retaining plates 5. Fig. 2 shows a similar machine for welding inclined plates. The electrode guide 6, Fig. 5, is provided with an adjustable member 14 which deflects the electrode as required. In a modification, Fig. 3, the stand 11 is dispensed with and the carriage is in two parts 2a on opposite sides of the work, spring-loaded towards each other and connected by a member 2c passed between the plates being welded. The carriage is raised by frictional engagement of driven rollers with the work. In a further modification, the carriage is raised by stepping magnets which engage the work. In a modified machine, Fig. 6, the retaining plates 5 and the electrode guides 6 are adapted to the welding of a T-joint between plates 12. Fig. 7 shows a machine having a non-consumable, e.g. graphite, electrode 16b, the weld metal being added in liquid or powder form from a vessel 17.

Title: Dispensing device for liquid fuels
IPC: F16K21/20
Filed: 1962-02-06
Abstract: 973,776. Hose couplings. SCHEIDT & BACHMANN G.m.b.H. Feb. 6, 1962 [May 27, 1961], No. 4485/62. Heading F2G. A fuel dispensing device for liquid fuel comprises a housing 1 disposed at and secured to the free end of a filling hose and valve and control means disposed in the housing, the latter being surrounded by a bushing 2 adapted to be coupled in fluid-tight manner with the filling pipe 5 of a vehicle tank, and arresting pegs 19 disposed at the free end face of the housing and adapted to co-operate with abutment members of a bayonet joining member on the filling pipe in order to secure the housing thereto. The valve and control means comprise an auxiliary valve 24 and a main valve 35 in series in the direction of the flow of fuel, the valve 24 having a valve stem extending axially in the housing in a direction opposite to that of the flow of fuel and which has secured thereto a cross bolt 22. The ends of the latter extend into diametrically opposed, inclined guide grooves 21 in the bushing 2 so that upon relative rotation between the housing and bushing the cross-bolt is lifted by axial movement and the valve 24 is opened; there are means responsive to the opening of the valve 24 for opening the main valve in order to start the flow of fuel from the filling hose to the filling pipe. As shown, and when the auxiliary valve has opened, fuel flows through the hose-connecting nipple 14, cross-bore 26 of the member 13, into the chamber 27 of the main valve 35 and through the bores 28 into a chamber 29 of the valve 24. An increase in fuel pressure lifts the plate 31 and fuel passes into the chamber 33 and bores 41 of a Venturi tube 40, through a fuelling spigot 36 into the filling pipe 5. The pressure of the fuel acts through slots 37 in the member 28<SP>1</SP> and on the annular face 38 of the main valve 35 to lift the latter against the force of a spring 39 so that fuel can fully flow through the housing 1. The Venturi tube 40 is axially movable against the force of a spring 44 and fuel passing the tube creates a suction to remove air present in a chamber 42, such air being continuously replaced by air flowing in a pipe 43. At the end of a filling operation, fuel rising in the pipe 5 prevents air being fed into the chamber 42 so that a pressure below atmospheric is created in the chamber and the hollow piston 45 moves downwardly to close the fuel passageway to prevent overfilling of a vehicle tank. The pegs 19 are mounted on pivots 20 and have inclined faces 46, a pull extorted on the filling hose causing the pegs to yield inwardly against the springs 47 to release the hose.

Title: Improvements in or relating to vapour cooling arrangements for electric discharge tubes
IPC: H01J19/36
Filed: 1955-02-16
Abstract: 766,618. Cooling systems for electric discharge tubes. TELEFUNKEN GES. Feb. 16, 1955 [Sept. 14, 1954], No. 4593/55. Class 64(3) In a cooling system for an electric discharge tube 1, in which the tube is cooled by evaporation of a cooling liquid, a conduit 7 for drawing off the vapour so formed is made at least in part of an insulating material having approximately the same dielectric constant as the cooling liquid so as to cause the potential distribution along said conduit, due to the difference in potential applied between its ends, to be substantially unaffected by the deposition on the surface thereof of drops of cooling liquid. Preferably the cooling liquid is water and the conduit 7 is made of a ceramic material having a dielectric constant of approximately 80. Fig. 1 shows an arrangement in which the valve anode 2 projects into a cooling chamber 3 to which water from a condenser 9 is fed through a pipe 4. An outer container 5 surrounds the chamber 3 and water vapour from the chamber 3 passes through the container 5 and the draw-off conduit 7 to a steam separator 8 the steam from which is passed to the condenser 9. The water from the condenser supplemented if necessary by make up water from a separate supply is fed back to the cooling chamber 3 to complete the cycle. The conduit 7 may alternatively comprise a glass tube through which the vapour flows and containing a rod or cylinder of material of the required dielectric constant.

Title: Improvements relating to electrical pulse generator chain circuits and to gating circuits embodying such chain circuits
Inventor: KRAMSKOY CHARLES MARK
IPC: H04J3/04
Filed: 1953-02-19
Abstract: 747,863. Pulse circuits; multiplex pulse signalling. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 2, 1954 [Feb. 19, 1953], No. 4640/53. Classes 40 (5) and 40 (6). A sequence of pulses is generated by a closed ring of switchable devices each of which is controlled by the preceding one in the chain, the ring including means which prevents the simultaneous generation of more than one sequence of pulses. Fig. 1 shows the application to a pulse time multiplex system in which n separate signal channels are gated sequentially to a common output channel Oc under the control of gates G1 ... Gn. The gates are opened by pulses from a ring of generators P1 ... Pn which each have one stable and one unstable state and may comprise, for example, cathodecoupled flip-flops so that each generator is switched by the preceding one and reverts after a predetermined period the output from the last generator Pn being differentiated by network D to trigger a blocking oscillator B which initiates a further pulse sequence. Any sequence of pulses which may be running independently by reason of the random switching of devices P1 ... Pn is rapidly suppressed by the blocking oscillator B which has a natural period greater than the sequence repetition period of the chain A. In a modification shown in Fig. 3, each channel signal is gated on the control grid of a valve 1 by a positive going signal applied from a pulse generator P1 ... Pn via a diode 3. An output from each generator is also differentiated by networks D1 ... Dn and the resulting positive peak occurring in coincidence with the leading edge of each generated pulse is passed by diodes L1 ... Ln and triggers a pulse generator Pg which generates a short negative-going pulse which holds the gating valve 1 closed via diode 5 for a short guard period at the commencement of each pulse generated by generators P1 ... Pn, Fig. 4 (not shown). In this way the possibility of any overlapping of the intervals when the gates G1 ... Gn are open is prevented. In a modification the gate valves 1 are pentode valves gated on their suppressor grids.

Title: A fluid flow control device
IPC: F02K3/10
Filed: 1956-02-14
Abstract: 797,562. Gas turbine jet propulsion plant. UNITED AIRCRAFT PRODUCTS, Inc. Feb. 14, 1956, No. 4665/56. Class 110 (3). [Also in Group XXIX] A device for injecting predetermined quantities of fuel before the turbine to ensure ignition of a reheat combustion chamber after the turbine comprises a valve closure member 35 controlling a port 24 and opened against the pressure of a loading spring 36 by a solenoid 27 which is under the control of a switch 41 actuated by a spring-loaded piston 72. To set the device in operation a manual switch in circuit with the solenoid 27 is closed causing the valve to open and fuel to flow from an inlet 39 through a passage 66, a port 61, and ports 23, 24 to the outlet 19. The flow through the port 61 causes a pressure drop which is applied to the piston 72 through a restriction 68 so that the piston moves to the left against the spring 71 until a shoulder 75 engages a lever 51 to operate the switch 41 to interrupt the circuit containing the solenoid 27, whereupon the valve member 35 closes and the piston 72 is spring- urged to the right. When the piston reaches its extreme right-hand position, a shoulder 74 actuates the switch 41 to re-energize the solenoid 27 and cause the cycle of operations to be repeated until ignition occurs in the afterburner and causes a thermal switch to break the circuit.
