Title: Improvements in or relating to moving picture cameras
IPC: G03B15/08
Filed: 1922-04-18
Abstract: 196,801. Bingham, G. W. April 18, 1922. Kinematograph apparatus; panoramic kinematography.-Panoramic pictures are photographed on a wide film by means of two lenses and cameras arranged one above the other, but diverging horizontally so that complementary images are formed in staggered relation on the film, with the inner edges of the pictures corresponding to continuous portions of the view photographed. The apparatus is enclosed in a casing 10 having transverse vertical walls 11, 12 to support the mechanism, and is fitted with lenses 13 arranged one above the other, but diverging horizontally so that the pictures taken simultaneously are on opposite sides of a line common to each. The wide film F is driven by mechanism operated from a shaft 18, and in passing through the apparatus is twisted so that its surface is first normal to the axis of the lower lens and then normal to the axis of the upper lens. The shaft 18 operates the sprocket shafts 24 through bevel and worm gearing 20, 23, the film passing over a shoe 36, yieldingly supported on an arm 39 oscillated by a cam 43 on the shaft 44 driven by gearing from the shaft 24. A similar shoe 36<a> engages the lower part of the film and co-operates with the shoe 36 to hold the film at the desired tension, except when released by the cam 43 to permit sufficient slack to enable the film to remain stationary during exposure. The shaft 44 also actuates the shutter 60 and the shutter cover 68, through links 54, 63 connected to discs on the shaft 44 and levers 56, 64 on the shafts 57, 65 carrying the shutter 60 and cover 68 respectively. The exposures take place during the up-stroke, the mechanism being arranged so that the shutter and cover perform the downward stroke simultaneously, while during the upward stroke the shutter is opened and then closed by the cover, exposure taking place during temporary stoppage of the film during delays caused by the withdrawal of the shoes 36, 36<a>. The twisting of the film between the focal planes of the lenses is effected by conical rollers 69, 71 arranged so that the film passes behind one roller and in front of the other of each pair.

Title: Electrical connector for aluminum wire
IPC: H01R4/62
Filed: 1954-04-14
Abstract: 755,272. Cable terminals; electroplating. AIRCRAFT-MARINE PRODUCTS, Inc. April 14, 1954 [April 23, 1953], No. 11042/54. Classes 38 (1) and 41. A connector comprises a ferrule 2 and a cup 6 having an elongated portion 8 fitting in the ferrule, and receiving the bared end 14 of a cable, and an enlarged portion 12 fitting round the cable insulation 18. The cup is filled with corrosion-inhibiting material such as petroleum jelly mixed with nickel powder and when not in use is closed by a cap 32. The connector is for use particularly with aluminium cables and both the ferrule and cup are preferably formed of aluminium, tin-plated to prevent formation of oxide. The oxide layer on the cable is removed by the action of crimping the connector on to the cable, the metal particles in the corrosion-inhibitor assisting in this by initially penetrating the layer. A method of tin-plating the connector is described wherein the connector is first etched with a mixture of concentrated nitric acid and hydrofluoric acid to remove the oxide coating after which it is washed and given a flash coating of zinc by dipping in a solution comprising zinc oxide, sodium hydroxide and water. The connector is then washed again and flash coated with copper in a bath of sodium carbonate, copper and sodium cyanide. After washing, the connector is electro-plated with tin in the usual manner. This plating is then heated to cause it to reflow, the connector at the same time being mechanically agitated and a final layer of tin is then electro-plated on the first one. Specification 673,198 is referred to.

Title: An improved manufacture of solid smokeless fuel
IPC: C10L5/04
Filed: 1947-04-29
Abstract: 631,355. Composition fuel. STANDARD OIL DEVELOPMENT CO. April 29, 1947, No. 11509. Convention date, Aug. 15, 1946. [Classes 50 and 55 (i)] A continuous process for making smokeless fuel briquettes from carbonizable material such as coal, lignite, asphalt, petroleum or the like comprises in the case of solids, carbonizing the finely divided material in the form of a fluidized bed, continuously withdrawing the finely divided hot coke to a further treating zone, continuously adding a hydrocarbon binder to the'coke in this zone and tumbling the mixture at a high temperature so as to form agglomerates. In the form shown, the apparatus comprises a carbonizer 10 and a rotary kiln 40. Finely divided coal, which may be preheated, is fluidized in feed hopper 1 by a gas entering at 2, and is carried through standpipe 3 into the carbonizer 10 to form a bed on the distribution grid 12, the bed being fluidized by superheated steam, hot flue gases or preheated air or oxygen entering through pipe 17. The bed is heated to a temperature between 800 and 2000‹ F., the actual temperature depending on the volatiles required, either indirectly, or by the sensible heat of the fluidizing gas, or by limited combustion of the coal or by circulation of hot char. Volatiles are withdrawn through line 22 and hot coke through line 25 to a kiln feeding device 31. Simultaneously about 3 - 15 per cent of a liquid binder such as petroleum, coal tar or pitch, preheated to 150 - 800‹ F., is added from tank 35. The sensible heat of the mixture entering the heatinsulated kiln 40 maintains its temperature at 700 - 1000‹ F. The mixture is tumbled in the kiln to form ball-shaped briquettes, which are allowed to bake to attain a high strength and to be free of smoky, low-boiling, binder constituents. If the starting material is a liquid, this is injected into a fluidized bed of coke, sand or the like maintained at carbonization temperature in carbonizer 10. In the Specification as open to inspection under Sect. 91 it is stated that the coke fines produced by the above-fluid carbonization process may be agglomerated by methods other than by tumbling in a rotary kiln, for example they may be mixed with a binder and the mixture briquetted under pressure. This subject-matter does not appear in the Specification as accepted.
