IPC: H03J5/24
Filed: 1953-04-23
Abstract: 782,071. Aerial coupling arrangements. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 23, 1954 [April 23, 1953], No. 11166/53. Class 40 (7). An aerial coupling arrangement for feeding selectively signals in two different wavebands to a receiver comprises a coupling impedance arranged so as to couple the aerial to each of two input circuits designed for operation one in each of the two wavebands. In one embodiment the coupling impedance consists of the primary winding 4 of an input transformer in series with a condenser 5. The aerial end of the impedance is coupled through a built-in medium wave loop aerial 1 to the medium wave contact 6 of the selector switch 11. Medium waves signals are developed largely across condenser 5. For short wave signals condensei 5 presents a very low impedance and signal transfer is between the primary and secondary of transformer 4, 8 and thus to the short-wave contact 7 of the switch 11. Trimming condensers 9 and 10 and a tuning condenser 12 common to both inputs complete the circuit. In the embodiment the inductance of the winding 4 presents a negligible impedance. However, in a modification (Fig. 2, not shown) the condenser 5 may be dispensed with and the primary winding designed to have a sufficiently high impedance for medium waveband signals to be generated across it.

Title: Improvements in or relating to light-sensitive silver halide emulsions
IPC: G03C1/06
Filed: 1949-04-27
Abstract: 658,434. Photographic silver halide emulsions. DU PONT DE NEMOURS & CO., E. I. April 27, 1949, No. 11211. Convention date, April 29, 1948. [Class 98 (ii)] A light-sensitive colloid silver halide emulsion contains 0.005 to 0.05 mol. per cent of thallium based on the silver content of the emulsion. The silver halide may be silver iodobromide predominating in silver bromide. The emulsion has increased contrast and good speed, and thin layers coated therefrom are less subject to local desensitization caused by abrasive forces or kinking of the layers. In examples, thallous nitrate is added to the silver nitrate solution used in the preparation of a gelatino silver iodobromide emulsion or is added before the completion of the precipitation and ripening of such emulsion. Emulsions prepared by the first method may be orthochromaticallysensitized with a pseudocyanine dye or may be panchromatically sensitized, or may, after ripening and washing, be sensitized with sodium thiosulphate, treated with gold chloride and mercuric chloride, and digested. In a further example, hexathallium sorbitol is added to the silver nitrate. In another example, thallous nitrate is added to a silver chlorobromide emulsion during the initial states of of preparation. In each case the relative speed, contrast, and fog are compared with the corresponding data for similar emulsions not containing a thallium compound. With some emulsions, the kink susceptibility is also compared. The thallium compound may also be added as thallous acetate, chlorate, sulphate, cyanide, fluoride, or oxalate. The emulsion binder may be gelatine, agar-agar, a polyglycuronic acid, zein, collodion, a water-soluble cellulose derivative (e.g. a substantially hydrolysed cellulose acetate, a cellulose ester of a hydroxymonocarboxylic acid, e.g. lactic or glycollic acid, or an alkali metal salt of a cellulose ester of a dicarboxylic acid, e.g. phthalic acid), polyvinyl alcohol, a partially hydrolysed polyvinyl acetate or an interpolymer thereof with an unsaturated compound such as styrene or maleic acid, or a water-soluble polyvinyl acetal. Sulphur sensitizers such as allyl thiourea, allyl thiocyanate, or another thiocyanate may be added. Specifications 376,746, 513,471, 519,895, 537,961, 542,703, 542,704, and 551,659 are referred to.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1927-04-28
Abstract: 270,319. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System Aktiebolag). April 29, 1926, [Convention date]. Refrigerating, absorption machines and processes for. - In apparatus of the type having all parts normally in open communication with one another and operated solely by heat, the liquor in the generator O is lifted periodically to a chamber D, whence it flows by gravity into the absorber A, the gas delivery passage 1 from the generator to the rectifier V and condenser K being closed while the lifting action is taking place. Refrigeration takes place over periods interrupted by the short intervals of the lifting or pumping action. An open-topped receptacle F arranged in the generator is fitted with a siphon 8, which may consist of a flat pipe or several small-bore pipes, and the pipe 1, which is of small bore in its upper part, extends from the receptacle F to the rectifier. A pipe 5 of larger bore than the pipe 1 extends from below the receptacle F to the upper part of the vessel D, which is in communication with the gas space of the absorber. A pipe 9 conveys liquid back from the rectifier to the generator, and the liquor flows from the vessel D to the absorber bv a. pipe 6 forming an interchanger T with the strong liquor pipe 7, which extends below the absorber. The generator is heated by an electric heater W, and the absorber and the evaporator G contain a pressure-equalizing gas and communicate by passages 3, 4. Assuming that the liquid in the generator is at the level of the top of the siphon, and therefore filling the receptacle F, on the application of heat liquid rises in the pipes 5, 1 and 9, the gas outlet through the pipe 1 thereby being sealed. Liquid is thus delivered into the chamber D, while the columns in the pipes 1 and 9 extend above the top of the pipe 5 to balance the pressure. The level in the generator and receptacle F falls until the pipe is unsealed, but the liquid column remains suspended in this pipe, and varies with minor fluctuations of pressure, until eventually the lower end of the pipe 5 is unsealed, the gas pressure in the vessel D and generator are equalized, and the column in the pipe 1 empties into the receptacle F. Gas is now free to flow to the rectifier and condenser and normal generation and refrigeration proceed. The liquor flows back through the pipe 7 until the receptacle F is filled suddenly and the pipe 1 is sealed, when the lifting action recommences. The invention is also described as applied to an apparatus having horizontal absorber and evaporator vessels and relatively short lifting pipes in the generator.

Title: Tilting Welding Gun
IPC: B23K11/31
Filed: 1967-03-10
Abstract: 1,164,507. Welding guns. BUDD CO. 10 March, 1967 [15 March, 1966; 9 Aug., 1966; 15 Dec., 1966], No. 11437/67. Heading B3R. A welding gun pivotable from an inoperative position to an operative position, comprises a fixed mounting bracket 10, a guide bar 12 slidable in the bracket, and a yoke 18 pivoted to the bar at 20, which carries a first electrode 64, a double-acting fluid pressure cylinder 22, and a piston-rod 26 carrying a cam bar 32 and a second electrode 62. Bar 12 slides on rollers 14, 16 mounted in bracket 10, and supports rollers 44, 46 which co-operate with cam bar 32, the latter being slidable on rollers 38, 40 journalled in yoke 18. An arm 58 on cam bar 32 cooperates with an adjustable stop 60 on bracket 10, and a second stop 80 on the bracket co-operates with a screw 78 on bar 12. In operation, fluid is supplied to cylinder 22, and rod 26, along with cam bar 32, move downwardly so that roller 44 moves from surface 50 on to surface 54, and thence on to surface 48, and roller 46 moves from surface 52, on to surface 56, and thence on to surface 50 of the cam, and yoke 18 is pivoted into a vertical position. Further movement of rod 26 moves electrode 62 into contact with the workpiece 82 as arm 58 contacts stop 60, thus limiting downward movement of the cam. Continued supply of fluid causes cylinder 22 to move relative to rod 26, whereby the yoke 18 and bar 12 are moved upwardly, so that screw 78 is moved away from stop 80, thus moving electrode 64 into contact with the workpiece. After welding, fluid is supplied to the other end of cylinder 22 and therefore this pressure, along with the action of a spring (74), Fig. 1 (not shown), moves the yoke 18 and bar 12 downwardly, to move the electrode 64 away from the workpiece, until screw 78 contacts stop 80. Further application of fluid pressure produces an upward thrust of rod 26, and cam bar 32 moves upwardly so as to tilt the gun into its inoperative position. Each electrode is water cooled, and spring (74) partially counterbalances the weight of the yoke, when the gun is used in an inverted position.
