Title: Improvements in or relating to photographic medium and methods of preparing same
IPC: G03C8/04
Filed: 1960-08-25
Abstract: A photographic medium is formed by vacuum evaporation of one or more of AgCl, AgBr and AgI and condensation of the vapours as a binder free layer of silver halide microcrystals not greater than 3.5 microns in thickness on a solid substrate such as glass, cellulose derivatives, polymers and polyesters or on a bonding substratum such as gelatin a lacquer or a tacky adhesive coated on the solid substrate or on a glass base coated with silicon monoxide.  The halides may be mixed together and evaporated simultaneously or they may be separately evaporated and their vapours allowed to mix prior to condensation.  The process is carried out in a normal vacuum deposition apparatus comprising an evacuated chamber, filaments of molybdenum, tungsten or tantalum and the substrate is located about 3 1/2 inches from the filaments so that its temperature is 30-50  DEG C.  The preferred vacuum is 10-4 to 10-6 mms. Hg. and the coating thickness is 0.3-3.5 microns.  Examples are given of coating the following substrates: (1) cellulose acetate coated with a lacquer, (2) polyethylene terephthalate coated with a water permeable colloid layer, (3) Scotch Tape polyester film.

Abstract: 976,526. Filters for liquids; crystallizing. PHILLIPS PETROLEUM CO. July 25th, 1963 [Aug. 6, 1962], No. 29486/63. Headings B1D and B1G. A liquid feed mixture of two or more components, one of which is separable from the mixture by crystallization, is forced by a pump 3, Fig. 1, into a chiller A, where one of the components is crystallized, and then into a cylindricalshell 4 having a filtering zone B where liquid passes through a cylindrical filter 114 and leaves by a pipe 16, Figs. 1 and 2. The crystal mass passes through a reflux zone C to a heater 17 which melts the crystals. Part of the melt is withdrawn through a pipe 18 and the remainder is forced back through reflux zone C to form reflux which effects crystal purification. A piston 21 in a cylinder 19 applies a back pressure to the material in the apparatus at a frequency of from 50 to 400 (preferably 150 to 250) pulsations per minute. A thermocouple 29 is connected to a temperature-recorder-controller TRC which operates a valve 30 in pipe 18 and is adjusted so that the rate of withdrawal of melt through ippe 18 is varied to maintain a desired rate of advance of crystals through reflux zone C. The withdrawal of filtrate through pipe 16 may be controlled by a solenoid valve 32 so that filtrate is removed only on the compression stroke of piston 21. The withdrawal of melt by pipe 18 also may be controlled so that it ceases during the compression stroke of piston 21. Lists are given of compounds which may be separated from mixtures containing them. The process also may be used to remove water in the form of ice crystals from fruit and vegetable juices and other liquid food products. The foregoing is substantially disclosed in Specification 807,100 (referred to) ; the present Specification discloses also a filter structure for zone B exemplified by Fig. 2. A housing 100, 104 is attached to the purification cylinder by flanges 102 and incorporates within an annular liquid-collecting space 108, a perforate cylinder 106 enclosing a coarse screen 112 and a fine screen 114 ; all these members are openended. Preferably the screen 114 is composed .of finer wires aligned with the direction of flow, and coarser wires perpendicular thereto, numbering, e.g., 350 and 20 per inch respectively ; the screen is of twill weave and may be rolled or ground. In an example, a mixture of methanol and water was treated in the apparatus to simulate the concentrating of beer.

Abstract: A foundry sand mixture comprises core sand and a binder therefor comprising a heat-hardenable resinous phenol-aldehyde condensate having admixed or combined therewith a minor proportion of an aromatic compound, having a plurality of nuclear substituents, reactive with the aldehyde, used in making the said resin, to form a resinous condensation product.  The preferred phenol-aldehyde condensate is made by heating at 140 DEG  to 212 DEG  F. a mixture of phenol and formaldehyde, in a molar ratio of 1 : 0.8 to 2.5, and sufficient alkali catalyst to give the mixture a pH of 7.5 to 11, until a stage just short of insolubility is reached, whereupon an acid, e.g. sulphuric acid, is added until the pH is between 7.5 and 9.0.  The aromatic compound, such as resorcinol, is then added, e.g. in amount of 1.0 to 100 per cent. by weight of the phenol in the original mixture, and the condensation is continued.  The resulting mixture is concentrated to give a binder containing 45 to 75 per cent. solids.  Other monohydric phenols and aldehydes, e.g. acetaldehyde may be used.  Other aromatic compounds specified are phloroglucinol, 3:5-xylenol, meta-cresol, 2:3:5-trimethyl phenol, 3 : 5 - diamino - phenol, meta - amino phenol and metaphenylene-diamine. Examples are given of cores made from sand, the above binder used, e.g. in amount of 0.3 to 6 per cent.
