Filed: 1970-11-20
Abstract: 1332939 Feeding ironing machines E & E PETERS GmbH 20 Nov 1970 [20 Nov 1969] 55363/70 Heading D1A Sheets and other pieces of laundry 30 are fed to a continuously driven feed belt 2 of a mangle or other machine 1 by an intermittently driven belt conveyor 16 arranged in front of the feed belt 2 and having at least a portion movable between positions in which laundry is fed onto the belt 2 or into an intermediate space between the feed belt and conveyor. In the apparatus shown in Fig. 2 the belt 17 passes round two non-driven rollers 19, 20 mounted on a frame 21 which is swing- able between vertical and inclined positions. In use, with the belt 17 stationary, the end of a sheet is loaded manually onto the belt abutting a transverse control bar 25. On depression of the bar 25 actuating a switch 26 the frame 21 pivots to the inclined position and the belt moves fast until the beam from a photo-electric light gate 27 is broken. The belt 17 then slows to feed the front of the article 30 onto the feed belt 2 and after a delay to allow this the frame 21 pivots to the vertical position and the belt 17 speeds up feeding the rest of the article into the intermediate space; a pivotable flap 28, connected by linkage to the frame 21, facilitates this. The belt 17 stops after the article 30 passes from the light gate 27. The intermediate space includes a roller 13 on a pivotable arm, a light gate 15 and two or more brush belts 9 for removing longitudinal folds in the article 30. When the article 30 leaves the light gate 15 upwards the roller 13 is moved to the left to hold the article against the brush belts 9. The belt 17 may not start and the roller 13 pivot back to the right on depression of the bar 25 until the previous article has cleared the light gate 15. For conveying small articles the frame 21 is maintained in its inclined position and the conveyor not controlled automatically. In a modification (Fig. 7, not shown), the conveyor is mounted on a frame which is pivotable to move it bodily between the two positions for feeding onto the belt 2 and into the intermediate space. For multi-track working a plurality of conveyors (16a, 16b) selectively driven independantly or synchronously may be provided (Figs. 5, 6 not shown) when the inner brush belts (9b) (9c) are selectively reversible for single or multi-track working.

Abstract: 1419777 Photographic colour diffusion transfer using a silver halide solvent POLAROID CORP 22 Dec 1972 [23 Dec 1971 24 April 1972] 59344/72 Heading G2C A composite print comprising a positive dye image over a negative image and separated therefrom by a light-reflecting layer is formed by developing at least one exposed silver halide layer having associated therewith a dye image-forming material with an aqueous alkaline processing composition in the presence of a silver halide solvent capable of forming a soluble silver halide complex and which contains no S atoms thereby forming an imagewise distribution of a diffusible dye image-forming material and transferring at least a portion of this to an image-receiving layer on a transparent support. The silver halide solvent may be a cyclic imide e.g. a uracil such as uracil or 5-or-6-methyluracil. This silver halide solvent may be used in combination with a second silver halide complexing agent which forms a relatively insoluble silver halide complex and which may be a compound of the Formula:- Where R is optionally substituted alkyl e.g. benzyl, or a compound containing S, e.g. it may contain a mercapto group or a group that provides a mercapto group on processing, e.g. a mercaptotetrazole such as 1-phenyl-5-mercaptotetrazole, or a mercapto substituted tetrahydropyrimidine. At least part of the silver halide solvent is generally in the processing composition. The processing composition may be in a rupturable container and may discharge its contents between the silver halide and imagereceiving layers or between the silver halide layer and its support when present. The processing composition may contain a reflecting agent and an optical filter agent. Normally all the layers of the material used are free of silver precipitating agent. The dye image-forming material may be a dye developer or an intermediate for an image dye. The use of a silver halide solvent containing no S atoms produces dye transfer images which retain their whites and have less tendency to discolour.
