Filed: 1971-04-19
Abstract: 1339349 Delivering sheets M D MARTIN 19 April 1971 [27 May 1970] 24915/71 Heading B8R Sheets cut from webs are delivered from a corrugating machine 1 at two levels by conveyers 2, 3, passing respectively on to roller conveyers 14, 7 against stops 34 on bars 36 adjustable' for length of sheet. From the conveyer 7, the sheets are passed at right-angles to a transfer conveyer 8 and a stacking conveyer 9, and thence on to a stack 11 on a conveyer 12, the delivery end of the conveyer 9 rising as the stack grows. The conveyer 8 is driven more slowly than the output of the machine 1 so as to cause overlap of the sheets, while the conveyer 9 may be slightly faster to reduce the overlap. The speed of the conveyers 7, 8, 9, and the corresponding conveyers 14, 16, 17, is synchronized with that of the machine 1, which varies according to the size of the sheets, and at the same time the speeds of the conveyers 7, 8, 9 (14, 16, 17) are maintained at a given ratio with respect to each other. In one form, the conveyers (e.g. 14, 16, 17) are driven by separate hydraulic motors controlled by three separate pumps, which are driven to produce the desired ratio by a shaft of the machine 1 or by a variable speed electric motor controlled by a tachometer driven by the shaft. In another form, the conveyers are driven by separate electric motors driven through a ratio control rheostat controlled by the tachometer.

Abstract: 279,617. Thornton, J. E. Oct. 9, 1926. Kinematograph apparatus.- In spoolcases comprising means for locking the contents therein such means being released by the insertion of the spoolcase into the camera or projector, the locking device operates on or engages a blank leader strip attached to the free end of the film. As shown in Fig. 1, the spoolcase A has a tangential film slot a, and a bolt E' extending into the slot from a bar e<1> by which it is carried on two pivoted arms E. The film has a slotted leader strip D at its free end, and is attached by means of a leader strip or otherwise to the core of a spool B having a central hole a'. The arms E extend across the hole a<1>, so that, when the spoolcase is placed in position on the spindle in the camera &c., the arms are depressed against the action of a spring e, and the bolt E' is drawn free from the slot in the leader strip. The spindle may have a conical end. In a modification the bolt E<1> is replaced by a plate having an aperture narrower than the width of the film, the width of a portion of the leader strip being correspondingly reduced. In a further modification, Fig. 4, the bolt E<1> is separate from the arms E, and is pressed by a spring e<4>, on to a surface e<2> carried by them. The arms slide in guides a<2> when the spoolcase is inserted in the camera &c., and permit the bolt E<1> to be pressed downwards over the inclined surface e<5>. The arms E may be within double walls of the casing, or on the inner sides of single walls. The arms may be dispensed with, as shown in Fig. 8, the spoolcase then comprising hinged portions A', A<2>, normally held together by a spring a' and having a narrow slot a<5> through which a leader strip of reduced width may project. The spoolcase may contain a single-width or a double-width film, such as are described in Specifications 279,220, 279,241, 279,593, and 279,594, and may be used in a projector such as is described in Specification 272,256.

Abstract: 1291676 Coating CANADIAN PATENTSDEVELOPMENT Ltd 19 April 1971 [31 March 1970] 25661/71 Heading B2E A polymeric substrate is provided with a coating of a condensation polymer by exposing the substrate to an electrical discharge, subsequently applying to the exposed substrate the monomeric precursor(s) of a condensation polymer, and polymerising the precursor(s) in situ on the substrate by stepwise polymerisation. The electrical discharge may be arc, glow discharge or corona discharge. Substrates mentioned are wool, cellulose, regenerated cellulose, polyethylene terephthalate, polyethylene, polypropylene, polybutene-1, polyisobutylene, polystyrene, polyvinyl chloride, polyacrylonitrile polyvinyidene chloride, polytetrafluoroethylene. The substrate may be in the form of films, fibres and filaments, woven, non-woven or knitted articles, extruded or moulded articles. The precursor(s) may be applied in solid, liquid or vapour state, e.g. when applied as liquids by dipping or spraying with a solution of a monomer or undiluted monomer. When two or more monomers are used the substrate is treated first of all with one of the constituent monomers and after drying treated with the second monomer. Preferred condensation polymers are polyamides, polysulphonamides, polyurethanes, polyepoxides or polyesters. The polyamides preferably are polymers formed by self-condensation of an amino acid or a lactam or by the copolymerisation of such amines as ethylene diamine and hexamethylene diamine with such dibasic acids as adipic, sebacic, undecandioc acid and dodecandioic acid or their acid chlorides or anhydrides. Preferred polyesters are those produced by homopolymerisation of a lactone or by the condensation of alkylene glycols with aromatic dibasic acid such a phthalic acid. The polysulphonamide may be poly(hexamethylene m-benzene disulphonamide). Applications mentioned are coating polyolefine substrates to improve the printability, crimpability, dyeability and thermal and photochemical stability of the substrate, improving the wetting characteristics of synthetic fibre tyre cords to increase the adhesion with the rubber of the tyre, improving the durability and wet strength of papers, improving the shrink-resistance of wool, and producing bicomponent fibres by fibrilating, cutting or splitting coated films.
