Title: Improvements in or relating to multicolour screens for photography
IPC: G03C7/08
Filed: 1921-05-12
Abstract: 163,311. Christensen, J. H. May 15, 1920, [Convention date]. Colour photography, screens for.-In making multicolour screens, the screen elements are produced by comminuting (as by emulsifying) liquids containing a dye and a mordant in such a form and under such conditions that mordanting does not take place before the elements are applied to the under layer, the object being to avoid any decrease in brilliancy and clearness of the screen due to the complete or partial precipitation of the dyes. Also to make the screen water repellant, the underlayer on which the particles are coated is provided with a coating of a cellulose derivative with the addition of a basic substance, as for instance a soap, e.g. sodium oleate. For producing the screen elements, instead of an aqueous solution of a basic dye mixed with tannic acid, the water as solvent is partially substituted by methyl or ethyl alcohol, and in the case of a solution of tungstic acid, molybdic acid or phosphotungstic acid mixed with a solution of basic dye, the liquids are rendered basic by the addition of ammonia which prevents precipitation. Where coloured basic particles of tungstic acid are used mordanting is effected by a subsequent treatment such as by an acid either in solution, or in the form of vapour. Inert substances such as gum arabic, dextrin, albumin may be included.

Title: Process and apparatus for the manufacture of thin to very thin films of polymers and copolymers of vinyl chloride, vinyl acetate and styrene by rolling
IPC: B29C55/06
Filed: 1956-05-03
Abstract: Thin to very thin films of polymers and copolymers of vinyl chloride, vinyl acetate and styrene are made from thicker films by producing the thicker film on a calender and, immediately after it has left the bight of the calender, stretching it to the desired reduced thickness while in a hot and plastic state by means of one or more drawing rollers rotated at a higher peripheral speed than the last rollers of the calender.  Films of thickness greater than 120 m  may be stretched to give films 10 m  to 80 m  thick if the ratio of the speed at which the film is stretched to the speed at which the thick film leaves the calender is within the range of 2 : 1 to 10 : 1. Stretching may be carried out in one stage or in several stages, heat preferably being supplied in the latter case to maintain the film in the plastic state.  The drawing roller may have an axis in the form of an upwardly-curved bow and may consist of a large number of cylindrical discs of the same size, e.g. made of wood, which are loosely connected together by pins or bolts so that they can be driven by two shaft connections fixed one to each of the two outermost discs with all the discs rotating together about an arcuate axis; the discs are covered with a loose cover made of plastic or rubber so that the film is also stretched transversely. One or more guide rollers which may have arcuate axes curved upwardly may also be provided after the drawing roller.  The polyvinyl chloride and copolymers of vinyl chloride may contain monomeric plasticizers, e.g. phthalic acid esters.  Specification 735,767 is referred to.
