Title: Rotatable Rectifier Assemblies.
Inventor: FRANLIN CHRISTOPHER GAVIN
IPC: G01R31/34
Filed: 1966-12-09
Abstract: 1,177,658. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. 6 Dec., 1967 [9 Dec., 1966], No. 55229/66. Heading H2K. A _rotatable rectifier assembly e.g. of a brushless generator has cut-out devices, e.g. electromagnetic devices, solid state switching devices or fuses 15 to protect the rectifiers 14 and indicator devices 17 rotatable with the assembly. Each indicator device 17 has an explosive charge which is fired to move a member 18 into the indicating position shown on the operation of the cut-out device across which it is connected. The members 18 in the indicating position interrupt a light beam acting on a photo-electric cell 19 connected to a position indicator 24 which may be synchronized by a marker interrupter (not shown) mounted on the rectifier assembly. The light beam may be provided by a lamp 22 and an incoherent light wire 20 or a light conducting tube.

Abstract: 1,247,058. Securing reels on spindles. EASTMAN KODAK CO. 21 Nov., 1967 [24 Nov., 1967], No. 55364/68. Heading F2U. [Also in Divisions G2-G3] A coaxially arranged spindle assembly for use in a cine projector or other web handling apparatus comprises a supply reel supporting member 18 which may (a) rotate freely on fixed shaft 371; (b) be driven by a friction drive providing a torque dependent on the reel weight; or (c) be driven by a friction drive providing a constant torque. Weight dependent torque mode.-Member 18 has a flange 374 which enters and frictionally engages the face of a drum member 373 freely rotatable on, but axially fixed on, shaft 371. The friction depends on the tilt of member 18 under the weight of a reel-finger member 375 is slidable on shaft 371 and has fingers 376 extending through apertures 377 in drum 373 to engage holes in flange 374. Therefore, when member 375 is axially shifted by control lever 424 away from member 18, fingers 376 disengage from flange 374, while lug 384 engages a lug 383 on extension 381 of a belt-driven pulley 379. Drive is then transmitted to member 18 through frictional engagment only with drum 373. Constant torque mode.-A friction clutch collar 386 is keyed to, and slidable on, extension 381 and has a wire 388 retained in groove 389 with an end forming a clutch finger 392. Therefore, with member 375 positioned with fingers 376 engaging flange 374, when collar 386 as slid away from member 375 by control lever 431, clutch finger 392 engages a lug 393 of the member. The drive of pulley 379 is then transmitted directly to member 18 through the constant friction torque between wire 388 and groove 389. Free rotation mode.-With collar 386 and member 375 bolts displaced towards member 18, no drive is transmitted to drum 373 and member 18, and these may rotate freely on shaft 371. The spindle assembly is of use in a projector as disclosed in co-pending Application No. 55365/68 during reverse winding, the weight dependent mode being applicable to film supplied from a cartridge, and the constant torque mode being applicable to film supplied from a heavy reel.

A roll of flexible, extensible film comprises a core 3 and a web 2 of said film wound under tension about the core, the core having at each end a coating 5 of a material e.g. paraffin wax, capable of cold-flow under pressure whereby as the inner layers of the web extend laterally due to the pressure of the outer layers, the coating cold-flows to accommodate the lateral movement and prevent curling of the outer layers about the inner layers. The film material is preferably polyvinyl chloride. The coating 5 is preferably from 0À001 to 0À003 inches thick and covers the ends of the core to a length of from 2 to 3 inches. The film preferably overlaps the coating by one inch leaving one inch clear at the end of the core.

Title: Method of and a developer for developing an electrical image on a surface
IPC: G03G9/12
Filed: 1974-12-24
Abstract: 1494353 Liquid electro-photographic developers and processes AUSTRALIA DEPARTMENT OF Mfg INDUSTRY SECRETARY OF 24 Dec 1974 [27 Dec 1973] 55700/74 Heading G2H An electro-photographic developer comprises (a) a toner medium capable of marking the surface to effect such development; and (b) a barrier substance having a viscosity exceeding two centistokes at 25‹C to which acts as an outer liquid phase to shield the toner, the viscosity of the barrier substance being less than the viscosity of the toner medium and of the total developer. In use the developer is moved over the surface under shear at a velocity which prevents contact of the toner medium with the surface except where the shielding effect of the barrier substance is modified by the electrical image to allow the toner medium to contact the surface. The developer is moved over the surface by a roller adjusted to apply such a pressure to the surface at such a velocity that the barrier substance spreads forwardly of the toner medium to act as a shield but is absorbed into the surface by the image pattern where it exists to allow the shear to apply the toner medium to the surface. The recording surface may be prepared by coating paper, film or metal sheet with a resin such as a polyvinyl acetal butyral copolymer, an alkyd resin, polyethylene; a polyester or an acrylic polymer, or with a photo-conductive composition. The barrier substance may be a silicone fluid, paraffin oil, an organic compound of chlorine or fluorine which is relatively solid at normal ambient temperature, a wax, lanolin, a fat, a vegetable oil, a thixotropic agent or a gelling agent. The toner medium may comprise a pigment ground with a resin in the presence of a solvent for that resin and may include an oil soluble dye. The pigment may be carbon black, aluminium, bronze, red iron oxide, black magnetic oxide, or an organic pigment.

Abstract: 1,159,889. Folding edges of non-metallic sheet material. CARL SCHMALE, [trading as CARL SCHMALE]. 8 Dec., 1967 [29 Dec., 1966; 9 Sept., 1967], No. 55918/67. Heading B5K. [Also in Division D1] An edge of sheet material is first folded singly and is then folded again before passing to apparatus at which seaming is effected by sewing, heating or adhesive, each folding being continuously pressed flat over the whole width. In Fig. 1, upper rollers 2a, 2b, 2c are journalled in pivoted arms 6 and are biased by adjustable spring means 7, contained in fixed housings 8, against respective fixed rollers 2d, 2e, 2f which engage the upper rollers through slots formed in a work-supporting plate 25. All the rollers are interconnected by gearing driven by a variable-speed gear arrangement. The upper rollers are interconnected by an endless belt 12 which passes over a tensioning roller 13 disposed beyond the seaming point, the lower run of belt 12 being supported by plate 25. A pair of rollers 17 is biased against belt 12 between the rollers 2b, 2c by spring means 23 in a fixed housing 22. An edge of the material, after being pressed between rollers 2c, 2f is folded upon itself by a scroll guide (27), the folded edge then being pressed under rollers 17 and between rollers 2b, 2e. A loop cut from tape 36, drawn from a reel 35, is then laid on the edge and the folded portion is then folded over the loop by a scroll guide 28. The finally folded edge is pressed between the rollers 2a, 2d and is then directed by a guide 29 to the needle 16 of a sewing machine 14. Projections from the guides (27), 28 are located in peripheral grooves formed in the rollers 2b, 2a respectively. In a modification, Fig. 7, the edge is turned up by a scroll guide 41, and is then turned over upon a flange 43 projecting from the lower end of a guide plate 42, by the lower surface of a rotary disc 44 having an axial projection 45 also acting as a guide surface.

As shown in Fig. 2, tubular extrudate 10 is passed from the oven through a constricting cone 12 and stretched by moulds 14, 16. A slidable table 27 is reciprocated by threaded shaft 24 through motor 26 and carries a cylinder 38 for opening and closing the mould halves which are pivoted together on rod 48 and operated by levers 50-64. Moulds 14, 16 close at the left of Fig. 2 on the stretched extrudate at pinch lines 68, 70 and move to the right stretching following extrudate and open at the right hand side of Fig. 2, removal of blown article 92 being facilitated by the tension formed. The opened mould then passes back to the left around the succeeding closed mould. As shrinkage of blown articles 86, 88 due to elastic recovery would increase the tension and possibly deform the mouldings, the speed of delivery conveyer 18 is correspondingly reduced to maintain it at the same level.
