Title: Improvements in or relating to methods of and apparatus for splicing the end portions of elongated uncured rubber bodies
IPC: B29B15/04
Filed: 1936-11-25
Abstract: 481,140. Splicing indiarubber; making inner tubes for pneumatic tyres. GENERAL TIRE & RUBBER CO. Nov. 25, 1936, No. 32261. Convention date, Nov. 30, 1935. [Classes 70 and 87 (ii)] [Also in Group XXIX] In apparatus for splicing the cut ends of an uncured rubber tube or other rubber article, pairs of clamping jaws which hold the two ends are brought together so as to press the ends together longitudinally, lateral flow of the rubber being prevented by inter-engaging fingers on the clamping jaws. As applied to the making of inner tubes for pneumatic tyres, a folded length of tube is laid on a table 1 against a gauge 3, and is cut by a knife 7 reciprocated in slots in uprights 10. The knife may be heated by electric heaters secured to it. After a valve body has been affixed, the tube is passed beneath a plate 57 supported above the table 1, and the ends are pressed together against slightly projecting teeth 54 on plates 53 recessed in plates which have interfitting fingers closing the gap between the plates 53. Similar plates are brought over the tube ends by a carriage 86, and are pressed vertically by cams operated by a handle 99, and the pairs of plates are then forced together horizontally by wedge-shaped cams operated by a handle 125. When pressure is released and the carriage retracted, the tube is removed and vulcanized. The tube is punched and a valve body is affixed by passing an open end of the tube over an arm 26 beneath a two-armed member 31 carrying a punch 29 and a pressing tool 30, and adapted to be rotated so as to bring the tools in succession over the tube and to be reciprocated vertically. The punch is supported in a raised position by a latch 48, Fig. 19, and on release is pressed down by a spring 43, and at the end of its stroke is raised slightly, by a spring 43a engaging the end of a slot 41a. The hole formed in the tube is placed over a spring- pressed plunger 28, the valve body placed over it, and the tool 30 pressed down on it. The downward movement of the member 31 with the tool 30 also causes the punch to be raised and latched by contact of a collar 45 against a sleeve 58.

Title: Improvements in or relating to water supply systems for concrete mixing machines
Inventor: WILSON SYDNEY
IPC: B28C7/12
Filed: 1952-12-22
Abstract: 729,959. Dispensing measured quantities of liquids. BLAW KNOX, Ltd. Dec.. 21, 19,53 [Dec. 22, 1952], No. 32503/52. Class 106 (5). A water supply system for a concrete mixing machine, comprises a measuring tank 3, Fig. 1, having an outlet controlled by a valve 17 for delivering measured quantities of water from the tank to the drum of the machine, a further tank 4, having a float controlled valve 6, Fig. 3, governing the water inlet 5 thereto, the float being located in the tank 4 and the valve being arranged to shut off the inlet before the latter is submerged, and a further valve 16 for allowing water'to flow from the tank 4 to the tank 3. The valves 16, 17 are spring-loaded to their closed positions and adapted to be alternately opened by an arm 18 connected to a manually-operable lever 20. When the valve 16 is opened, water flows from the tank 4 by way of a pipe 8, chambers 9 and 11 and an inverted U-shaped pipe 23, Fig. 3, to the tank 3 until the latter is filled, this being indicated by a float 46 rising from a cage 45 into a dome 44 of transparent material communicating with an open-ended tube 46. The lever 20 is now moved to open the valve 17 and hence permit the water to flow from the tank 3 back through the pipes 26 and 23 and chambers 11 and 12 to an outlet 21 which delivers it to the drum of the concrete mixing machine. As the level of the water in the tank 3 falls it uncovers one end of a flexible pipe 33 the other end of which is connected by a pipe 34 to the top of the U-shaped pipe 23. The siphoning action in the latter is thus broken and the water flow arrested. The measured quantity delivered may be varied by adjusting the position of a rod 29 which passes through a stuffing box 30 and carries an inverted cup-shaped member 31 to which one end of the pipe 33 is connected. The rod 29, which together with the dome 44 is enclosed by a water-tight U-shaped plate 27 in the tank 4, is adjusted by means of a scale and clamped by a nut 40 and a flanged collar 41.

Alloy pellets of small dimensions for P-N junctions in semiconductor apparatus are made by making numerous identical recesses 5 in one or more flat plates 4, masking the spaces between the recesses, depositing the same amount of alloy material in each recess, removing the masking and heating the plate or plates, preferably in a hydrogen atmosphere, until the alley material melts or contracts upon the bottom of the recesses so that on cooling it solidifies in balls 8 of equal size. The plates 4 may be of beryllium copper, which after formation of the recesses 5 is hardened and given a hard coating, e.g. by electrolytic oxidation, which the alloy material will not wet. The spaces between the recesses are then masked as by an apertured sheet 6 of tantalum foil, or by a photo-lithographic process. The recesses and masking are then coated with the alloy either in one step or by superposed layers of the separate constituents of the alloy, by vapour deposition, thermal decomposition or chemical process. Before deposition the plate may be coated with a layer of inert material such as paraffin. The masking is then removed and the plate heated until the alloy melts.
