Title: Improvements in or relating to spiral slide-fastener elements
IPC: B29D5/06
Filed: 1959-07-24
Abstract: 880,887. Moulding slide-fasteners. YOSHIDA, T. July 24, 1959 [Oct. 8, 1958], No. 25561/59. Class 87(2). [Also in Group XXV] A helical slide fastener is produced by locating a heated thermoplastic wire, e.g. of polythene, in a helical groove around a flat straight mandrel by rotatably advancing the mandrel carrying the wire and then retracting it without rotation, moulding a projection on each turn after emission from the groove, and cooling the shaped helix. A mandrel 1 carrying polythene wire is advanced one pitch of a helically grooved body 3 under the action of cam 37 on shaft 35 controlling lever 52 and is simultaneously rotated by a rack and pinion device 42, 44 engaging said shaft through a clutch. The clutch is then disengaged and the mandrel retracted leaving a coil A in the grooves B of body 3, which is provided with a heater. Cam 36 on shaft 35 operates through levers 53, 57 and shafts 22, 25 to close dies 6, 7 and mould an engaging projection on each turn of the flat helix. The shaped helix then passes through a guide 14 to maintain the correct pitch, and is cooled by air from nozzles 12.

Filed: 1925-10-14
Abstract: 242,258. Roberts, A. Nov. 3, 1924, [Convention date]. Road-traffic signals on vehicles; semaphore signals. - The signalling-member of a stopping and turning indicator comprises a number of arms a pivoted on a common spindle and each having a pin-and-slot connection with the adjacent arm so that the arms are splayed to a fan formation when moved to the signalling position, and a lamp h mounted on the spindle or one of the arms is arranged to illuminate the arms so that a portion of the signal is rendered visible from the front and a portion from the rear. In the inoperative position the arms are arranged to fold into a box b, which is internally padded to prevent rattling of the arms and is provided with a leaf spring for retaining the arms. Operation of the signal is preferably effected by a pull on a Bowden wire e connected to a lever d, the retain. ing spring being released by the pull. The uppermost arm is preferably channel-shaped towards its inner end so as to prevent loss of light and render a triangular portion visible from the front as shown in Fig. 3, while the lowest arm is L-shaped with the flange pointing rearwardly so that the lower part of the signal is visible from the rear as shown in Fig. 1. The central arms, which are located on opposite sides of the lamp, have flanged ends with a pin-and-slot connection l as shown in Fig. 6. In addition to the closure of the box opening effected by the arms in their inoperative position, a hood f is provided to assist in rendering the box watertight.

Abstract: 1342918 Film cartridges EASTMAN KODAK CO 19 April 1971 [6 April 1970] 25918/71 Heading G2A In a roll film cartridge in which film is wound from a supply chamber 16 on to a core 13 in a take-up chamber 17, the external diameter of the core is equal to or greater than the internal diameter of the supply chamber. The film strip 14 is interwound with protective backing paper 15, and as shown the backing paper is attached to the core by a piece of adhesive tape 33, whereas the film strip is not attached to the backing paper but engaged round the spool merely by frictional contact alone. The effective diameter of the core 13 may be taken as including the initial winding of backing paper thereon before the film strip reaches the core. The arrangement is intended to prevent buckling due to the development of film and backing paper at different rates between the supply and take-up rolls.

Title: Improvements in or relating to the manufacture of thin sheets, films and the like products of cellulose formate
IPC: C08J7/04
Filed: 1936-09-29
Abstract: Thin sheets, films, and like products, of cellulose formate are rendered impermeable to moisture by coating with a varnish containing resins, softeners, waxes, or other water-repelling substances, and formic acid.  The formic acid exerts a swelling and slight solvent action on the cellulose formate and thus ensures a permanent union between the varnish coating and the base sheet.  The varnish may contain cellulose esters such as cellulose nitrate or acetate, and solvents such as acetone, butyl acetate, and ethyl acetate.  The sheets of cellulose formate may be coated by dipping, spraying or painting.  In an example, thin sheets of cellulose formate are coated with a varnish comprising alcoholic shellac solution, nitrocellulose dissolved in butyl acetate, tricresyl phosphate, phenol ethers sold under the trade name "Toplast," and formic acid.  Specification 243,032, [Class 140], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the coating of sheets of cellulose or cellulose derivatives other than formates, e.g. cellulose hydrate, cellulose acetate, and cellulose ethers.  This subject-matter does not appear in the Specification as accepted.
