Title: Improvement in method of making uniform low shrinkage cellulose derivative sheeting
IPC: B29C48/08
Filed: 1938-03-26
Abstract: 512,967. Cellulose derivative films. KODAK, Ltd. March 26, 1938, No. 9301. Convention date, March 26, 1937. [Class 2 (ii)] Cellulose derivative sheet or film having uniform shrinkage properties and suitable for use in. aerial photography, is produced by depositing in the form of a film on a filmforming surface a solution of a cellulose derivative in a volatile solvent, removing solvent until the sheet is hard enough to be stripped from the surface without undue elongation, curing out residual solvent, and finally subjecting the sheet to annealing treatment in hot water to remove internal strains. Throughout the process excessive longitudinal tension is avoided ; thus, for example, the film may be deposited on a polished drum and various expedients may be employed to facilitate ease of stripping. Any subbing or backing treatments are applied in the curing section and while the film is passing over the driers. In the figure, hopper 8 supplies a thin layer of cellulose derivative solution to the surface of wheel 1, the formed film leaving the wheel at the stripping roll 23 and passing into the curing chamber 11. Subbing or backing solutions are applied to the film from the troughs 49 and 50. After leaving the curing chamber 11, the film passes through the water box 25 where it meets a counter current of hot water of progressively increasing temperature, and then through a further curing chamber 39 to a wind-up 47. The film may pass through more than one water box and, before reaching the water box, it may pass through a number of curing chambers. Examples are given of the. preparation of cellulose nitrate and cellulose acetate-propionate film. Specifications 287,880, [Class 2 (iii)], and 480,645 are referred to.

Abstract: 725,728. Side-delivery rakes. VAN DER LELY N. V., C. April 8, 1953 [April 11, 1952], No. 9510/53. Class 6 (3). A side - deliverv rake, of the type having a series of oblique parallel rake-wheels 9, is chacterised in that the main frame 6 is invertible about a longitudinal axis so that the rake may deliver either to the left or right of its line of travel. The rake is pushed by a tractor 1 having a transverse tubular support 2 across its front end, the frame 6 being carried by a castor-wheel 15 and brackets 4, 5 secured to the tube 2 and to the ends of the frame 6 and of a strut 19 respectively. A cross-bar 20 connects the strut 19 with the frame 6. The tractor may support a mower-bar 12 on one side to cut an adjacent swath 14 and tow an offset pick-up loader on its other side to collect the raked swath 11. The width of the swath raked is adjustable either by the addition or removal of rakewheel, Fig. 3 (not shown), or by the alteration of the inclination of the frame 6 to the line of travel. This may be effected by mounting the frame 6 and strut 19 on sector-shaped brackets 30, 31 having spaced alternative holes 32, the brackets being also adjustable along the tube 2. The mounting means 4, 5 lies in the same horizontal plane 35 as the pivotal axes of the cranks 8 carrying the rake-wheels, and the tube 36 carrying the castor-wheel stem 38 is symmetrical about this plane, so that bodily inversion of the rake does not disturb the working levels. The cranks 8 are all attached by springs 41 to lugs 42 on a shaft 43 which is movable by a lever 16 and cable 46 to raise all the rake-wheels in unison or to vary their pressure on the crop. On inversion, the castorwheel stem 38 is inserted into the opposite end of the tube 36 and the springs 41 are attached to lugs 42a so as to occupy the positions 41a.
