Patent GB-125117-A (GB)
IPC: G01S1/72
Abstract: 125,117. Bragg, W. H. May 26, 1916. Locating subaqueous sounds.-The direction of submarine sounds is determined by immersing in the water a body lighter than water and so shaped that its oscillations are impeded less in one direction than others, this body being provided with means such as a microphone for rendering the oscillations sensible to an observer. The Figure shows one construction. The body A consists of an ellipsoidal glass shell made in two parts fitting together. A microphone is carried within, and circuit wires are led out through the glass. The device is suspended by flexible connexions D from a wire frame which may be slipped in an iron case which is supported by a rod so that it may be turned in any direction. Instead of a microphone, a magnetophone, such as a coil oscillating in a magnetic field, may be employed, or the movement of the body may set up changes of air pressure in a chamber connected to a listening- tube. Reference has been directed by the Comptroller to Specification 15320/15.

Title: An improved remote control receiving apparatus operating according to the frequency of impulses method
IPC: G08C19/16
Filed: 1940-08-15
Abstract: 545,319. Electric indicating systems. LANDIS & GYR SOC. ANON. Aug. 15, 1940, No. 13032. Convention date, Aug. 16, 1939. [Class 40 (i)] In a system in which indications are given by a ballistic instrument in accordance with the frequency with which signal-impulses are received the receiver comprises a change-over relay controlling two circuits each comprising an inductance which stores energy during impulses or spaces as the case may be and discharges the energy through a corresponding valve which may be any suitable rectifier, e.g. dry or electrolytic, or a gas discharge tube which does not respond to normal voltage applied by the relay. The inductances may be transformers. As shown relay E1 connects up inductances 6, 7, for impulses and spaces respectively and when the circuits are broken the stored energy gives an impulse of uniform intensity irrespective of the frequency to the operating coil 13 of a ballistic instrument having a differential winding 14 which takes current through resistances 15, 16 to compensate for the reverse current, due to the imperfection of the rectifier, through the operating winding. In modifications, Figs. 3 and 4 (not shown), the inductances have secondary windings connected to the instrument through half-wave or fullwave rectifiers and the impulse contacts are shunted by rectifiers to provide a path for the "extra current" through the primary windings.

[Also in Group XXXIV] In a machine-tool with an automatic-setting- control for accurately positioning and clamping the table and cross-slide, the work-table 15, Fig. 2, is supported by rollers 27, 31, 46, held in guideways in a cross-slide 18 by cages 28, 32, 47 and retaining-bars 26, 30. The rollers 27, 31 run on V-guides 23, 22 of the cross-slide and rollers 46 on a flat guide 45, the guides being protected by guards 34, 35, 55 secured to the slide and strips 57, 43 attached to the sides of the table. The end of each guide is protected by a spring-strip 36, Fig. 6, attached to the carriage and guided by a rod 38 on the slide to form a coil 37 which is cleaned by a felt-block 141 on a frame 41 pivoted at 42, a counterweight 142 keeping the block in contact with the strip. Telescopic sheet-metal guards 44, Fig. 1, protect the slides 22, 23 and 45. The slide 18 is mounted on similar roller-guides 16, 17, Fig. 1, on the machine-bed 11, these being repeated at the opposite-side of the bed, the guides 16 each having one side only of the Vee. The table and slide are moved to pre-selected positions by ball-bearing lead-screws, driven by electric-motors stopped electronically when a signal from a measuring-device associated with each guide-way is given to an electronic control, this control may be set manually with the aid of an indicating-panel 20 or by punched-cards or punched or magnetic-tape. Simultaneously with the stoppage of the table and slide, a clamping device which acts without affecting the setting, is actuated by the electronic-control. For the table and slide, a metal strip 62, Fig. 2, is attached to the slide and runs between long strips 59, 60 attached to the table, the strips being clamped together by wedges 69 acting through ball-bearings 71. The wedges are actuated by opposed pairs of hydraulic cylinders 72, 73, Fig. 8, or by springs or solenoids.

Title: A method of coating articles by evaporation and deposition of metals
IPC: C23C14/26
Filed: 1945-05-25
Abstract: In a method of producing metallic coatings by the evaporation of a non-wetting metal from a filament of tungsten, tantallum, molybdenum or columbium, the metal to be evaporated is heated on such a filament as an alloy with another metal which causes the metal to be evaporated to wet, to adhere to, and to spread over the filament and by the continued application of heat to evaporate and then be deposited on the article to be coated.  The wetting metals may be aluminium, magnesium, vanadium, barium, strontium, iron, nickel, cobalt, manganese, thorium, chromium, titanium, platinum, palladium, rhodium and iridium, of which iron, nickel, cobalt, platinum and palladium are preferred, and the non-wetting metals are silver, gold, copper, zinc, tin, antimony, cadmium, bismuth, lead, thallium and indium.  The wetting metal should be capable of alloying with the filament metal and the metal to be evaporated and should have a boiling point sufficiently above that of the metal to be evaporated to prevent its evaporation during the process.  The coating process may be performed in a vacuum. Specifications 592,693 and 592,700 are referred to.

Title: Improvements in or relating to dish-washing machines
IPC: A47L15/04
Filed: 1941-10-16
Abstract: 551,349. Dish-washing machines. ELECTROLUX, Ltd. (Aktiebolaget Elektrolux). Oct. 16, 1941, No. 13328. [Class 138 (i)] In a dish-washing machine of the kind having a movable spraying member and a housing rotatable about its own axis and enclosing a member such as a pump wheel for circulating liquid through the machine, the pump housing is rotated by the circulating liquid and is connected by a transmission element to the spraying member, the path of movement of which is defined by guide members. The base of the washer is shaped to provide a sleeve 14 rotatably supporting a pump housing 15 surrounding a pump wheel 16. Above the pump wheel a valve 20 is urged to closed position by a spring 22 and can be opened by a lever 25 to open a passage to the compartment containing the support 12 for the dishes. The pump delivers to a tubular member 38 forming a pivot for a lever 39, 49, the first part 39 being hollow and delivering to a rectangular spraying pipe 45. The pipe 45 is free to travel at right angles to itself to and fro across the washing compartment and is guided by a rail 47. The pump wheel is driven by a belt 31 and an electric motor 32. As it is driven the drag of the water rotates the housing 15 causing the pivot 38 to move in a circular path. Stops 51, 52 co-operate with a roller 50 at the end of the lever to swing this when the spraying pipe is at its central position. In a modification a pivot 71 rotated similarly to the member 38 is connected by a hollow link 72 to a spraying ring 75 restrained to travel in a rectangular path with rounded corners determined by cooperating guide rails 82, 84. The guide rail 82 may be toothed to rotate a pinion 81 so that the spraying ring rotates as its axis travels, or the pinion may be driven by friction. With the object of assisting the movement over dead points, and of acting as a brake at certain parts of the path, a piston 87 in a cylinder supplied with water from the pump through a ball valve 91 bears against a projection on the side of the link 72. The ball valve is prevented from completely seating by an adjustable pin 92.
