Abstract: 112,287. Submersible & J.-L. Motors, Ltd., and Durnford, C. W. Oct. 10, 1916. Armatures and field magnets, cooling; casings; coils and conductors; motors, cooling.-In a combined submersible pump 20 and electric motor 1 in which the pump serves to circulate water through the motor casing for cooling purposes, means, such as needle valves, are provided for controlling the flow of water before it enters and when it leaves the motor casing. The pump draws the water through the intake 21 and delivers it to the outlet 22 which includes a brass cylinder 24 with sawcuts 25 through which some of the water passes into a chamber 26 from which it passes through a cylindrical passage 27 and a duct integral with the motor casing. An opening 29 in the duct through which the water enters the motor is controlled by a needle valve, the outlet 31 being similarly controlled by a needle valve 33. By a suitable arrangement of ribs, the water is caused to circulate in a zigzag direction in the space between the casing and the stator. Some of the water also passes through the air-gap between the rotor and stator and through the stator slots which are closed and of such a width that one conductor 18 only can be accommodated between the sides of the slot as shown in Fig. 8. The rotor bars 10, Fig. 9, of the motor which is of the induction type are secured to the end ring 11 by expanding them by means of steel pins 48 and filling the space 49 with solder, or the pin 48 may be coated with copper and the end of it left flush with the surface of the ring 11. The stator leads are lead out for a considerable length without any joint through a gland 51. The three conductors 52, 53, 54 are bound with vulcanizing tape 56 and covered with a canvas tube 57. The lower end of this tube fits over the mouthpiece of the gland, Washers 61 of plastic insulating-material are provided to ensure a tight fit. The end parts 42, 44 of the bearings are formed with grooves which are filled with grease to prevent access of water to the roller bearings 39, 43 and thrust bearing 40.

Title: Improvements in or relating to the treatment of metal meshes or foils so as to render them taut
Inventor: CASSMAN HARRY
IPC: H01J19/30
Filed: 1947-06-03
Abstract: 689,564. Making metal meshes and foils. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 29, 1948 [June 3, 1947], No. 14609/47. Classes 83 (ii) and 83 (iv). [Also in Groups II and XL (a)] In a method of treating a thin metal mesh or foil, particularly for use in electric discharge tubes or in the manufacture of mosaic electrodes, the mesh or foil is extended on a frame and secured at its edges thereto, and is coated with a metal which will alloy with the metal of the mesh or foil to produce shrinkage thereof, and the coated and secured mesh or foil is heated to cause alloying of said two metals and taughtening of the mesh or foil in a substantially planar condition on the frame. The mesh or foil may be coated before or after it is mounted on the frame. In the example described a silver mesh 1 having 400 filaments per linear inch and a thickness of 0.0004 of an inch is cemented to a frame 2 of stainless steel, or " Invar " (Registered Trade Mark), according to the Provisional Specification, by applying a suspension of colloidal silver in oil to the edges of the mesh, applying the mesh to the frame in an extended condition, and subsequently drying out the suspension by heat so that the mesh is left adhering to the frame 2 by means of a thin layer of silver 3. The mesh may be secured to the frame by applying a nickel tape to the edges of the mesh and welding the tape to the frame through the interstices of the mesh. Before or after mounting the mesh on the frame it is coated with a thin film 4 of gold, 10<SP>-5</SP> of an inch thick, by plating, evaporating or sputtering. The mesh is then heated in air or vacuo to a temperature of between 300‹ and 500‹ C. until alloying is observed, accompanied by a taughtening of the mesh.

Inventor: LEIGH BERTRAM ROBERT
IPC: B60L1/02
Filed: 1960-04-26
Abstract: 909,592. Automatic temperature-control systems. STONE & CO. (DEPTFORD) Ltd., J. March 28, 1961 [April 26, 1960], No. 14624/60. Class 38 (4). A system for the control of a heating means divided into two or more parts 1, 2, wherein one part is switched with a delay from another part, comprises a negative resistance-temperature coefficient resistor 10 having a bias heater 11, which is energized when the part 1 is switched on. A thermostat 6 unshunts a relay coil 5 at a given temperature closing contacts 3 and opening contacts 13, the latter de-energizing the heater 11 causing resistor 10 to decrease its shunting effect on another relay coil 9, which eventually closes contacts 4. If the contacts 6 reclose before relay 4, 9 operates, the heater 11 is re-energized and the coil 9 continues to be shunted. Further shunted relays 9-11 may be provided arranged either in cascade or parallel. A number of resistors 10 may be grouped in a polygonal fashion (Fig. 2, not shown) with a common heater 11 wound round and enclosing them.

Title: Improved driver's brake valve device
IPC: B60T13/36
Filed: 1931-05-20
Abstract: 378,951. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of McCune, J. C. ; Edgewood, Pennsylvania, U.S.A.) May 20, 1931, No. 14921. Convention date, June 18, 1930. [Class 103 (i).] In a driver's brake valve more particularly for straight air systems comprising a spring 9 the degree of compression of which is adjustable by a manually operated handle 38, the upper end of the spring 9 is provided with a cap 29 having rollers 32 pivotally mounted thereon and adapted to be engaged by a rotatable cam 34 to which the handle 38 of the valve is detachably secured, the cap is guided by a fixed stem 31 so as to be vertically but not rotationally movable. A strut member 43 is provided to transmit the movement of the cam mechanism if the spring fails. Compression of the spring 9 by the handle 38 depresses a piston 8 which closes the exhaust valve 18 by means of a spring 25 and opens the supply valve 12 which allows pressure fluid to pass from the reservoir pipe 16 though the chamber 7 to the brake cylinder supply pipe 45 until the pressure in the chamber 7 exceeds the pressure of the spring 9, when the piston 8 moves up to allow the valve 12 to reclose and obtain a lap position. The brake cylinder pressure is thus graduated and leakage is compensated by the consequent lower pressure in the chamber 7 allowing the piston 8 to descend and open the valve 12. The brake is released by reducing the pressure of the spring 9 and allowing the piston 8 to rise and lift the valve 18. The cap 29 is irregularly shaped so that only a portion of the periphery engages the guiding wall of the casing to reduce friction to a minimum. The cam 34 terminates in a tongue 36 engaging the slotted offset portion 37 of the handle 38. A pin 39 mounted in the portion 37 moves in a track 40 which prevents the handle being removed except in the full on brakes position in which position the pin is opposite an opening extending to the top of the casing.

Title: Improvements relating to turbo-jet propulsion units in aircraft
IPC: B64C29/00
Filed: 1959-05-01
Abstract: 860,497. Aircraft. DAIMLER-BENZ A.G. May 1, 1959 [May 2, 1958], No. 14953/59. Class 4. [Also in Group XXVI] A turbo-jet propulsion unit is mounted in an aircraft so as to be tiltable to produce vertical thrust, part only of the intake diffuser, designed for subsonic conditions, being tiltable with the unit, and the forward part of the diffuser, designed for supersonic conditions, being fixedly mounted to the airframe. Fig. 1 shows a unit buried in a wing having fixed frame parts 17, 171, and 21. Frame parts 16 16<SP>1</SP>, are tiltable with the unit about an axis 25. A flap 23 is pivoted at the wing trailing edge. The axes 27, 28, and 29 of the turbine assembly, afterburner, and nozzle respectively, incline progressively downwardly in rearward succession, so that in the normal position (full lines) some vertical thrust is produced (more than half the lift with a high angle of incidence), and the angle through which the unit must be swung to produce a large vertical force is reduced. In the tilted position (chain lines), the part 15 of the diffuser fixed to the unit is suitable for low speed operation, e.g. during landing or take off. A gap 24 is formed by flap 23, through which air is sucked by the ejector effect of the nozzle exhaust, to remove the boundary layer from the wing and provide a cooling air flow between the flap and the exhaust gases. In the normal position, gaps 22 are formed between parts 16 and 21, through which an airflow is similarly induced for removal of the boundary layer and cooling of parts 21. Fig. 2 shows the installation of two pairs of units in wing parts extending between a central and two side fuselages. The components 17, 18, 19 of the supersonic intake extend laterally to serve a pair of units and are swept back.

Filed: 1976-04-13
Abstract: 1497995 Position determination STANDARD TELEPHONES & CABLES Ltd 13 April 1976 15086/76 Heading G1A [Also in Division G4] A fibre optic acoustic monitoring arrangement comprises two parallel adjacent optical fibres 2, 3 equal in length, means for transmitting an optical carrier simultaneously in both fibres but in opposite directions, separate means 7, 8 for detecting the optical signals transmitted through each fibre, means for providing each detecting means with a reference optical signal coherent with the optical carrier, and means for determining the relative time delay between the acoustic modulations of the optical signals received at the detecting means from the two fibres resulting from the same acoustic disturbance to the fibres. As shown, the system is used for intrusion detection and in particular for locating the position of intrusion. The optical carrier is provided by a laser 1, partially reflecting mirrors 5, 6 being utilized for transmitting the optical carrier into the fibres. The reference optical signal is also provided by laser 1 via an optical fibre 4 of the same length as fibres 2 and 3 and a partially reflecting mirror 9. The detecting means 7 and 8 are provided by photodiodes and their outputs are applied to an oscilloscope 14 via respective amplifiers 10, 11 and variable delays 12, 13. If the acoustic disturbance is at the exact mid point of the fibres 2, 3 then both signals generated in the two fibres will be in phase at the detectors. If the disturbance is to one side or the other of the mid point then the signal in the appropriate channel will lead the other. By adjusting either of the delays, the two signals can be brought into coincidence on the oscilloscope and the difference between the two delays can be translated into a distance from the monitoring station.

IPC: B01D1/22
Filed: 1963-04-17
Abstract: 983,279. Evaporators, film-type; distilling water; spray producers. WESTINGHOUSE ELECTRIC CORPORATION. April 17, 1963 [May 25, 1962; May 28, 1962], No. 15138/63. Headings BIB and B2F. In an evaporator of the type wherein liquid is evaporated in the form of a film flowing down an inclined surface, the surface is provided with downwardly-extending ridges 31, Fig. 6, which have grooves 32; the liquid is distributed over the upper portion of the surface and is received in the grooves from whence it spreads, by surface tension, as a thin film over the surface. The cross-sectional area of the grooves preferably diminishes in the downward direction. In the apparatus shown in Figs. 10 and 11, which is suitable for the distillation of water, there is a series of inclined plates 20, 21 joined together to form a serpentine structure. The plate structure forms a heatexchange barrier between chambers 13 and 14. Saline water is sprayed into chamber 13 through apertures in two tubular manifolds 55, 56 on to the plates, the range of the sprays 70 and 71 being periodically varied by liquid-pressure control device 58 in such a manner that the liquid impinges on each plate in succession. The vapour given off from the downflowing films of saline water on the plates is drawn into compressor 26, and the compressed vapour is pumped through conduit 25 into chamber 14 where it condenses on and gives up heat to the under sides of plates 20, 21. The condensed water is withdrawn through conduit 27. The saline water to be distilled is supplied through conduit 57 to device 58 which contains a cylindrical rotor 66, Fig. 12, having a cam surface 67 associated with ports 68 and 69. These ports lead to manifolds 55 and 56, respectively. The rotor is turned on shaft 62 at a steady rate, e.g. 5 r.p.m., by motor 61; and the velocities of sprays 70 and 71 vary in such a manner that during the time that spray 71 is decreasing from its maximum to its minimum velocity, the velocity of spray 70 is increasing from a minimum to a maximum. In an alternative embodiment, the liquid is sprayed successively on to plates 20, and then successively on to plates 21. The non-evaporated brine collects in troughs 24, and is withdrawn through conduit 28.
