Title: Improvements in apparatus for the manufacture of bead wires for pneumatic tyres
Inventor: LOWE JACK MILNER
IPC: B29D30/48
Filed: 1958-07-22
Abstract: 920,082. Making tyre bead cores. DUNLOP RUBBER CO. Ltd. July 9, 1959 [July 22, 1958], No. 23432/58. Class 144 (1). A tyre bead core is wound from a single rubberized bead wire 24 by being guided on to the grooved peripheral winding surface 1b of a rotatable former 1, the wire guide 25 being movable axially of the former under the control of a rotatable cam 38 to produce a core of superposed layers of convolutions with the convolutions of each layer seated in the grooves formed between the convolutions in the adjacent layer or layers. As shown, the former surface groove 1b has a cylindrical base with divergent side walls and is designed to wind a core of hexagonal section composed of seven layers respectively of 4, 5, 6, 7, 6, 5, 4 convolutions. The former 1 is mounted on a rotatable driven shaft 2, and the wire guide, comprising a grooved pulley 25, is mounted on a pivoted lever 26 to overlie the former groove 1b The pulley 25 is biased towards the winding groove by feeding the wire over a pulley 31 mounted on an extension of the lever 26. The lever 26 is pivoted to a slide 29 movable axially of the former in a housing 30 and coupled, by means of a slotted block 33, with one end of a lever 34, the lever 34 being pivoted intermediate its ends to the machine frame 5 and having its other end 36 formed as a cam follower engaged in a cam groove 37 of a cylindrical cam 38. The cam 38 is rotatably mounted coaxially with the shaft 2 on a flame extension 39 and has a 37-tooth driving sprocket 40 which is operable in one-tooth steps, defining the axial positions of successive convolutions, by a pawl 42 carried by a pivoted arm 44. The arm 44 is connected by a link 47 to one end of a centrally pivoted lever 49 the other end of which carries a cam follower 51 which is engageable in an inverted V-shaped cam groove 52 in a block 53 carried by the former 1 in a predetermined angular position corresponding to the end of one complete revolution of the former during winding. The lever 49 is also linked to a stop pawl 65 so that, when the cam groove 52 engages the follower 51 at the end of each revolution of the former to effect movement of the link 47, and thereby rotation of sprocket 40 and cam 38, the pawl 65 is engaged with the sprocket 40 to limit the rotation to a step of one tooth. Subsequently the cam groove 52 moves the lever 49 to disengage pawl 65 and to reset the pawl 42. Reverse rotation of the sprocket is prevented by a flat spring 66. To permit removal of the wound bead core, the former comprises two fixed diametrically-opposed peripheral segments 11, 12 mounted on a backplate 15, and two intervening segments 13, 14, each pivoted at one end 16, 17 to the backplate and collapsible radially inwardly about their pivots by a rotatable arm 22 having its ends engaged in slots 18, 19 in the segments. In an alternative construction, instead of a cylindrical control cam a plate cam is used rotating in, or parallel to, the plane of movement of the guide slide.

Abstract: 501,360. Timing ignition. LUCAS, Ltd., J., and SMITH, F. W. Aug. 27, 1937, No. 23500. [Class 7 (iv)] Pressure operated means for adjusting the relation of the interrupter lever to the actuating cam is provided with a manually-operable adjustment. From the piston or diaphragm f, which is responsive to induction, oil or other engine-created fluid-pressure, projects a non- rotatable stem h surrounded by concentric sleeves m, i. The other sleeve i is connected with the carrier of the interrupter lever, for example by a ball-joint. The inner sleeve m is formed at the outer end with a head n which can be manipulated by hand or a tool. Accidental movement due to vibration is prevented by a spring-pressed serrated washer o. Specification 441,771 is referred to.

Abstract: 453,674. Colour photography. DOLGORUKI, E. SANDERS-, 14:, Wetherby Gardens, Earl's Court, London. Sept. 2, 1935, No. 24458. Drawings to Specification. [Class 98 (ii)] A method of producing dyestuff images for colour photography or kinematography includes the steps of subjecting an exposed emulsion to a photographic reversal process and utilizing the second metallic deposit produced by reversal to control the production of colourless portions in the emulsion by destruction of a diffused dyestuff. The emulsion may be preliminarily treated with the diffused dyestuff or a colourless or coloured body convertible into the dyestuff may be incorporated in the dyestujf prior to the first development. After development and washing the silver is removed by permanganate or bichromate and sulphuric acid or preferably the acidified solution of a ferric salt. The remaining silver halide is re-exposed to light and redeveloped. The second exposure to light may be replaced by treatment with a sodium hydro sulphite solution containing sodium bisulphite or with diamidophenol developer made alkaline with sodium carbonate. The dyestuff is destroyed at the points where there is metallic silver, either with known reducing or oxidizing reagents such as sodium hydrosulphite and potassium bromide. The second silver deposit may be replaced by mercury, copper or lead. The first silver deposit may be converted to silver iodide and the emulsion redeveloped, after exposure to light with a developer which does not reduce silver iodide. The dyestuffs used may be Chorazol Sky Blue FF or Diamine Pure Blue FF for blue-green, Diamine Fast Pink G or Benzopurpurine 10B for magenta, Mordant Yellow GG or Chrome Fast Yellow GG for yellow. Specifications 133,034, 249,530, [both in Class 98 (ii)], 395,718, 397,188, and 426,260 are referred to.

Apparatus for continuously forming flexible hoses of the type formed of a strip of flexible material, which includes a continuous rib with a reinforcing member embedded therein and fins along its longitudinal edges, and is formed into a succession of convolutions of equal diameter which are secured together, comprises primary pressure and guiding means 5, 7 to weld the adjacent fins together in a continuous seam and secondary pressure and guiding means 6, 8 to cause helical movement of the structure. The second means 6, 8 are at a point spaced from the first means 5, 7 and cause helical movement without imposing undue stresses to the weld. As shown the extruded profiled band 1 comprising a body 2 reinforced by a stiff core of synthetic material and two wings 3, 4, passes between the grooved wheel 5 and the mandrel 7 at 22 and then between the grooved wheel 6 and the mandrel 8 at 23 and then at 24 and 25. The two mandrels 7, 8 rotate in the opposite direction to the two wheels 5, 6, and are each driven separately. The wings 3, 4 of the band 1 overlap and are pressed together firstly between wheel 5 and mandrel 7 at which point a gas flame may be applied. The tube as formed has an oval cross-section but as the formed tube is pushed off the mandrel 7 by the rollers 5, 6 it progressively assumes a circular section. The formed tube is supported first by the mandrel 8 and then by three rotating cylinders, one of which is shown at 17. The mandrel 7 may be cooled by means of compressed air from pipe 26 passing through ventilating canals 29. The other mandrel and wheels may be cooled.

Class 98(2) Existing images in dyestuff or other organic substance capable of reducing ferric ferricyanide are treated with a composition including a soluble ferric salt, a soluble ferricyanide and an acid to produce a Prussian Blue image. The method is particularly but not solely concerned with production of sound tracks on cinematograph film, and rhe existing images referred to may be those made by colour development or by imbibition printing from a relief matrix, the latter case avoiding silver salt sensitisation and processing of an imbibition blank to make a sound track in silver or toned silver and having the desired absorption in the infra-red area. Dyes and other substances for making the existing images by imbibition are listed, and a coupler-containing colour developer is quoted. Two examples are concerned with the imbibition method using edgewise application of a composition as above thickened with sodium alginate or with a specified cellulose derivative to convert the first-formed images into Prussian Blue.
