Patent GB-406337-A (GB)
Title: Improvements in the manufacture of films, sheets and the like
IPC: C08L1/10
Filed: 1932-08-23
Abstract: In the production of films, foils, sheets, and the like, a liquid solution of a cellulose ester or ether in a neutral solvent is extruded through an orifice and the shaped product is coagulated directly in a solution of a salt of hydrochloric acid in a concentration of at least 15 per cent.  The salt chosen is one which has substantially no swelling action on the cellulose derivative. Sodium chloride and calcium chloride are specified. The salt may be present in the form of an aqueous or alcoholic solution.  The specific gravity of the coagulating liquid may be adjusted with regard to that of the film-forming solution so as to control any tendency to displacement due to differences of specific gravity.  The film-forming solution may contain from 5--30 per cent of cellulose derivative which may be cellulose acetate, nitrate, or other ester or mixed ester, or methyl, benzyl, or other cellulose ether or mixed ether, or a cellulose ether-ester.  The solvent may be a volatile solvent or solvent mixture, or a higher boiling liquid such as diacetone alcohol, ethyl lactate, diethyl tartrate, ethylene glycol monoacetate, dioxane, methylene ethylene dioxide, or an ether or ether-ester of dioxane dicarbinol.  Plasticisers and also non-solvents such as water, benzene, toluene, chloroform, or carbon tetrachloride, may be present in the film-forming solution.  During coagulation the films may be stretched longitudinally and transversely.  After passing through the concentrated salt solution, the films may be passed through more dilute salt solutions, or a bath in the form of a long channel may be used, the concentrated salt solution being introduced near the shaping orifice, and water or other diluent being introduced at points along the length of the bath so as to dilute the solution progressively.  The films may be formed upon a band or drum and the film-forming solution may be spread on the support by a doctor blade, or by the rear lip of the extrusion device, or by an adjustable roller.  On completion of coagulation, the films may be washed with water or dilute solutions of salts or solvents and dried.  Drying may be carried out on the drum or other support on which the films are produced or in a separate apparatus. The upper part of the ascending side of the forming drum may be provided with an enclosing heating segment.  White, coloured, or matt effects may be obtained by adding to the film-forming solution a salt which reacts with the salt of the coagulating liquid to form an insoluble compound.  In an example cellulose acetate solution is extruded into a 20 per cent aqueous solution of calcium chloride and the film is received on a rotating roller.  In another example, the coagulating liquid is a saturated solution of sodium chloride. Specifications 308,323, [Class 2 (ii)], 343,062, 400,589 and 405,692 are referred to.  The Provisional Specification describes also the employment of dilute salt solutions as coagulating liquid. Sulphates, phosphates, or other salts may be used instead of chlorides.

Title: Improvements in and relating to methods of rolling metal sheets and plates
IPC: B21B1/22
Filed: 1935-08-23
Abstract: 448,165. Rolling sheets. ASBECK, G., 11, Wahlerstrasse, Rath, D³sseldorf, Germany. Aug. 23, 1935, No. 23700. [Class 83 (iv)] Tapering; cross rolling.-Plates or sheets are made from a wedge-shaped slab p, Figs. 1 and 2, by first rolling it transversely in a tapering pass, Fig. 5, with uniformly increasing pressure towards the narrow end so that that end is spread out to make the slab have parallel sides, and then rolling the slab longitudinally from end to end in parallel rolls to reduce its tapering thickness to uniform thickness and so elongate it. In the case of double wedgeshaped slabs they are first passed through parallel rolls to make them of uniform thickness and then rolled as above, first transversely in a tapering pass and then longitudinally in a parallel pass. In Fig. 12 the top roll can be tilted by hooks h which pull the slides g in which are located pins e of the bearing-blocks d so that the bearing-block bears against the pass-adjusting screws i.

Title: Improvements in the manufacture and production of esters
IPC: C07C67/08
Filed: 1926-09-27
Abstract: 259,204. I. G. Farbenindustrie Akt.- Ges. Oct. 5, 1925, [Convention date]. Esters; diethyl phthalate; ethyl acetate; methyl butyrate; butyl formate; boric esters.-Esters are produced from a reaction mixture comprising an acid, an alcohol, and an additional liquid which is insoluble in water but is capable of forming a mixture with water having a boiling point below that of any of the components and below that of the ternary mixture of alcohol, water, and additional liquid, the reaction mixture being heated under elevated pressure in such a way that water is distilled off together with the additional liquid but without any substantial amount of alcohol. Suitable additional liquids are benzene, toluene, carbon tetrachloride, and hexane. The esterification may be accelerated by addition of catalysts, such as sulphuric, phosphoric, and other mineral acids, pyridine and its homologues, or neutral inorganic salts, an addition of one per cent or less being generally sufficient. According to an example, ethyl alcohol and phthalic anhydride in theoretical proportions are heated to boiling under a pressure of 15-20 atmospheres in a pressureresisting vessel, provided with a distillation column, into which benzene is continuously introduced. The distillate consists substantially of benzene and water, and the benzene is separated and returned to the reaction vessel. When water no longer distils over, the remainder of the benzene is distilled off and the diethyl phthalate suitably purified. Reference is made also to the production of eaters from the acid-alcohol mixture obtained by the partial oxidation of an alcohol. The Specification, as open to inspection under Sect. 91 (3) (a) states that the process may be applied in the production of ethyl acetate, methyl butyrate, butyl formate, and the esters of boric acid. This subject-matter does not appear in the Specification as accepted.

Filed: 1964-06-09
Abstract: <PICT:1031963/C6-C7/1> Substrates, particularly vertical glass sheets or dropped particulate substrates, are vacuum coated by rotating a crucible 13 having an open end axially thereof and containing molten material, such as in a ring 26 held against the inner surface e.g. groove 22 of the crucible by centrifugal force, evacuating the space external of the open end, e.g. in a vacuum chamber 11, heating the molten material, preferably by directing an electron beam 24 from a generator 25 through the open end upon the surface thereof, to vaporize material therefrom, and positioning a substrate 27 in front of the open end for receiving deposition of vapour emitted axially. The vapour may be focused with hot reflecting surfaces 17 into a directed stream, the direction of which may be changed by tilting the drive shaft 19 of the crucible within vacuum seal 20 e.g. by altering position of drive motor 18. Material such as wire 21 may be fed into the crucible e.g. through vacuum lock 23 to maintain a reservoir of molten material. A pool of material of high boiling point may be first formed, e.g. of Zr, Nb, Ta, Hf, U, W or Mo, or nitride of Al or B, or boride of Hf, Zr, Ti or Ta, then additional material, such as Al, having a lower boiling point, may be fed into the pool e.g. as wire, rod 21, small pieces or air-driven powder to be instantly vaporized.  Rapid hangover may be effected from one additional material to another, e.g. from Al to Ag.  For alloy coatings, a plurability of wires or rods may be fed into the pool which is maintained at a temperature above the boiling points of the alloying constituents; an example of Nb-Sn alloy is given.  Two opposed horizontal crucibles may be used in the vacuum chamber for coating both sides of a substrate such as continuously moving thin sheet (see Fig. 6, not shown).  The crucible may be rotated about a vertical axis with open end up (see Fig. 8, not shown) at a rate sufficient to depress the centre of the surface of molten material so that vapour travels axially from the open end.
