Patent GB-595588-A (GB)
Title: The manufacture of refractory products
IPC: C04B33/13
Filed: 1942-03-26
Abstract: Refractory products are prepared by mixing refractory materials, such as silica, zirconia, thoria, alumina, magnesia, beryllium oxide, chromium oxide, carbon, silicon carbide, or mixtures thereof, with binding-materials, a small amount of water, and a small amount of a wetting and dispersing agent, moulding under pressure to the desired shape, and baking at a high temperature.  As binding-materials may be used inorganic substances such as lime, clay, silicates, boric or phosphoric acid or magnesium chloride, or organic materials such as dextrin, glue, albuminoids, sulphite-cellulose lyes, alginates, pitches, tars, linseed oil, or natural or synthetic resins; preferably, however, a solution of an organic agent which renders the mass sufficiently plastic to be handled at ordinary temperatures, e.g., dextrin, glue, casein, or a natural or artificial resin, and an organic agent which forms a coke at higher temperatures so constituting a network to hold the particles together, e.g., monoses, polyoses, sugars, molasses, or the like, is used as the binding-agent.  The following materials are specified as wetting-agents: condensation and sulphonation products of aromatic hydrocarbons or their derivatives with aldehydes, alkyl and aralkyl naphthalene sulphonates, sulphonated fatty alcohols, fatty acid, fatty acid amides, or fatty acid esters, water-soluble products of the reaction of ethylene oxide on fatty acids, fatty alcohols, fatty acid amides, and amines, homologues of phenol, alkali alginates, and sulphite-cellulose lyes.  If the wetting agent contains no alkali metal, a small quantity of an alkali metal compound can be added to the binder, while if no silica is present in the refractory a small quantity, e.g., in the form of crushed quartz, is added in order that a film of alkali metal silicate may be formed on the refractory particles.  Preferably, the material is formed as a non-foaming paste, but if a light porous product is required air may be incorporated.  The Specification as open to inspection under Sect. 91 describes also the following features: the use as refactory material of natural or artificial silicates, e.g., aluminium silicate; the use of barium silicate as a binder; the use of emulsions or dispersions of pitches and tars in water or other liquid as temporary binding-agents, in which case the wetting-agent acts also as the emulsifying-agent; the incorporation of saponin if a porous product is required; the heating of the mass to 80-100 DEG C. to facilitate manipulation when pitch or tar emulsions are used; and the incorporation with the pitch or tar of a refractory fat clay.  These features are not described in the Specification as accepted.

IPC: G03D5/04
Filed: 1949-02-16
Abstract: 669,405. Photographic processing apparatus. KODAK, Ltd. Feb. 16, 1950 [Feb. 16, 1949], No. 4265/49. Class 98 (ii). [Also in Group XXX] Exposed sensitized sheet material is successively developed, fixed, and washed in a sequence of separate compartments through which the sheet material is transported by a series of moving webs presenting a wet surface to which the paper adheres solely by surface tension, each web consisting of a set of spaced parallel endless belts and each set of belts travelling over rollers or pulleys on a common shaft and alternating on this shaft with rollers or pulleys carrying the next set of belts so as to provide an uninterrupted path for the sheet material from the first web to the last web and so that the sheet material does not pass between any of the said rollers and associated belts and is transferred from one web to the next solely by the sheets adhering by surface tension to the second web when the sheets pass over the shaft supporting both webs, jets being arranged in the compartments for spraying the treating fluid on to the sheet material as the latter travels through the machine on the webs. As shown, exposed and wetted cut photographic paper sheets 12 are fed successively through developing, fixing, and washing compartments, in which they are sprayed from jets 11 in pipes 10 with the appropriate liquid, by horizontal and vertical groups 6, 7 of parallel spaced endless belts, each belt being supported on and driven by pulleys 9 which may be formed integrally with their shafts 8 and each of which carries in interdigitated relation both groups of belts. If desired the separate webs may be driven at different speeds by suitable choice of pulley size. Each compartment has a drain so that the treating liquid never reaches the top run of the belts 6 at the bottom of the compartment. To lengthen the washing period the washing compartment may include an extra set of vertical belts 7 over which the sheets travel from and back to the lower horizontal belts in the compartment. If desired, the processing liquids may be applied to the sheets by immersing the lower runs of the lower belts 6 or the lower halves of the corresponding pulleys 9 in baths of the liquid.

Abstract: 416,666. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Sch÷neberg, Berlin. Feb. 14, 1933, Nos. 4536 and 4537. Convention dates, Feb. 15, 1932. [Class 98 (ii).] In the production of photographic dyestuff images in photographic layers which contain a silver image and are diffusely coloured with dyestuffs, or contain dyestuff-forming substances in the emulsion, by subsequent destruction of the dyestuff or dyestuff-forming substance at the image or non-image portions, the silver image is of a vigorous character such that the amount of silver is greater than that required for the destruction, the surplus silver being subsequently removed by a suitable reducing agent. Thus, a vigorous image is produced by intense exposure or development and the developed and fixed image is placed in a solution of Diamine Pure Blue FF and treated with a thiocarbamide-citric acid solution. After thorough washing, the image is treated in a bleaching bath. Dyestuff discharging baths as described in Specifications 395,718and 397,159 may be employed. The process may be applied to images containing dyestuff-forming substances produced by the process described in Specification 416,566. A bleaching agent such as Farmer's reducer may be employed ; preferably a bath containing copper, e.g. comprising copper sulphate, sodium chloride and nitric acid, or cupric chloride and nitric acid, to avoid any discharge of the dyestuff. After bleaching, the silver salts are removed in a fixing bath. The photographic material may comprise a number of superimposed layers or particles of different colour. Specifications 397,188 and 397,192 also are referred to.
