Abstract: 764,441. Pneumatic elevators. SIMON, Ltd., H. Nov. 14, 1955 [Jan. 21, 1955], No. 1867/55. Class 78 (1). Material, e.g. grain, seeds and flour mill stock, is delivered to the lower end of a vertical elevator pipe g by a shoot a and is directed into the air stream d by oppositely-directed baffles b, c, each of which is shaped to retain a cushioning supply of material thereon. An adjustable slide h is provided between the baffles and a loaded flap i is provided for releasing material when the pressure on the slide becomes excessive. The air stream enters the apparatus through openings e controlled by slides f. A normally-closed flap j opens automatically to release the material when the suction fails.

Class 103 (1). In an internal shoe-drum brake for motorcycles, the rear wheel brake is fitted with a more powerful hydraulic brake than the front wheel and the front wheel is equipped with additional mechanically operated means such that, for example, if the hydraulic brake were so designed that 40 per cent of the total braking force were applied to the front wheel brake and 60 per cent to the rear wheel brake, the relationship could be so altered, e.g. during weight transference during braking, by the additional brake actuating means such that the front wheel brake would take 60 per cent altogether and the rear wheel brake 40 per cent of the total braking force. Mechanical operation is achieved by a Bowden cable mechanism so arranged that its core 10 and sheath 11 each act separately from one another on doublearmed brake levers with arms 6 and 7 carrying pins 8 and 9 such that pins 14 and 15 mounted on lever arms 12 and 13 actuate the brake shoes 3 and 4 in addition to the hydraulic actuation by the wheel brake cylinder 2.

[Class 56] Vessels such as ampoules having wide bodies and extended necks are made by narrowing a wide tube at one end and fusing thereto a narrow tube forming the neck of the vessel. Fig. 8 shows an automatic machine for carrying out the process. The wide tube 52 and the narrow tube 55 are coaxially mounted in chucks 51, 56 rotated at equal speeds and transported to a series of working positions at which the different operations are performed. At position II, the wide tube is heated and is narrowed by pressure of a tool 53 ; the two tubes are then heated to fusion point at position V, where the lower tube is raised to bring the ends into contact ; at position VI, the joint is enclosed in a heated mould 57 and blown by compressed air admitted through the pipe 58. An alternatve method of joining consists in pressing the parts together at fusion point and then moving them slightly apart, this motion being effected by the rotation of a suitably shaped cam. The following alternative methods of narrowing the wide tube are mentioned, viz.: (1) the tube is constricted by drawing out and cut at the constriction ; (2) the tube is sealed, shaped from within by a mandrel 17 Fig. 3, and the end 19 is cut off ; (3) the tube is sealed and the end is centrally heated by a jet 23, Fig. 5, and blown out by compressed air admitted at 22, the opening being subsequently shaped by a mandrel 13.

Abstract: 504,667. Rubber. JONES, F. C., and RELIANCE RUBBER CO., Ltd. Jan. 28, 1938, Nos. 2787 and 9601. [Class 70] Rubber sheets and other articles are provided with relief ornaments or other devices in contrasting colours by applying a completely cured element or elements to a partially cured base, and completing the cure so that the element or elements are vulcanized to the sheet or article. In carrying out the invention, the basic rubber sheet or article is moulded in accordance with usual practice except that the mould is opened before the time of complete curing. The preformed completely vulcanized relief elements are then placed in position, the mould closed, and the cure completed. The completely cured elements yield when the mould is closed and regain their original form when the mould pressure is released. The mould may be designed to form recesses in the basic material to fit the applied elements, which however still stand in relief when-the article is finished. The preformed relief elements may be provided with a textile backing. Prior to applying a relief element, its contacting side may be treated by cleaning, with cement, with powdered sulphur, sulphur solution accelerator, or polysulphide solution to give a good joint.
