Title: Process for the deoxidation of steel baths
IPC: C21C7/06
Filed: 1937-12-20
Abstract: 508,012. Deoxidizing steel. ROCHLING'SCHE EISEN UND STAHLWERKE GES. Dec. 20, 1937, No. 35195. Convention date, Dec. 28, 1936. [Class 72] In the deoxidation of steel baths with calcium carbide, the melting point of the calcium carbide and its reaction products is reduced to below the melting point of the steel by the addition of one or more of the fluorides of alkali and alkaline earth metals and aluminium, the carbide content of the mixture used being at least 50 per cent. Oxides and carbonates of alkali and alkaline earth metals and aluminium in an amount up to 10 per cent may be added to the carbide mixture especially when the latter contains fluorspar and cryolite.

Title: Improvements in vitaminised products
IPC: A23L33/15
Filed: 1957-11-15
Abstract: In the process claimed in Claim 1 of Specification 744,091, the aqueous dispersion of protein in which one or more substances having vitamin activity has or have been homogeneously distributed and in which an antioxidant has been incorporated is, prior to the coagulation of the protein, absorbed under reduced pressure by the grains of a previously degassed, edible absorbent substance of vegetable or animal origin e.g. seed cakes, beet pulp or cacao pods, so that the grains contain and are coated individually with a film of coagulated protein.  According to an example, 700g. of a vitamin A concentrate previously mixed with 4 kg. of a sorbitol ester and with an antioxidant were emulsified in a dispersion of 3kg. gelatine in 15 litres of water.  This emulsion was slowly added to 45 kg. of cacao pods of calibrated particle size during heating under vacuum in a mixer at 70 DEG C.  After a partial drying, 3 kg. of dry tannin were introduced to effect coagulation and drying was continued until a product of 10% moisture content was obtained, which finally was coated with a hot solution of sodium alginate.ALSO:In the process claimed in Claim 1 of Specification 744,091, the aqueous dispersion of protein in which one or more substances having vitamin activity has or have been homogeneously distributed and in which an antioxidant has been incorporated is, prior to the coagulation of the protein, absorbed by the grains of a previously degassed, edible absorbent substance of vegetable or animal origin, e.g. seed cakes, beet pulp or cacao pods, so that the grains contain and are coated individually with a film of coagulated protein.

Abstract: 397,193. Decorticating and cleaning fibrous leaves. HYDRAULIC ENGINEERING CO., Ltd., Charles Street, and MANGNALL, A. R., White Lodge, Westminster Park, both in Chester. Dec. 24, 1931, No. 35742. [Class 120 (i).] A machine for decorticating and cleaning fibrous leaves and stems, e.g. the leaves of sisal, flax, hemp, or ramie, comprises two or more pairs of coacting crushing rollers 1, Fig. 1, gapped at intervals along their length so that any one pair of rollers will crush the leaf only at intervals the gaps 16, Fig. 2, of one pair being in register with the crushing parts 15 of an adjacent pair. The gapped crushing- rollers may be smooth, corrugated or fluted. After treatment by the rollers 1 the opposite sides of the crushed leaves are cleaned in scutching devices 19, 20. The butt ends of the leaves are aligned against a plate 10 in a feed shoot 9, 9a and the leaves are picked up therefrom by horizontal trays 8 secured between discs 2 driven by belts 5 and are transferred at the top of their path to the belts 5 and fed thereby to the crushing rollers 1. A weighted stop 18 is provided to engage and delay the tip ends of the leaves to allow for the greater spreading of the butt ends when crushed. The cleaning or scutching devices 19, 20 operate respectively on the butt ends and on the remainder of the leaves which are fed therethrough by overlapping rope conveyers 21, 22, 23 arranged as shown on pulleys 24 .. 33. The butt ends are cleaned successively on opposite sides by rotary beaters 36, 37 cooperating with breast plates, the beaters 36, 37 being arranged at different levels, so that a line through their axes is inclined at substantially 45‹. The leaves are similarly scutched over the remainder of their length by beaters 38, 39. Water or other liquid may be sprayed on to the fibres during cleaning, and rubbercovered squeezing rollers provided to remove excess moisture. A guide-plate 43 and stripper fingers 44 are provided and. the treated leaves are delivered on to a curved rod 45 and deflector plate 46. After decortication the fibres may be dried in the sun or by the use of heated air and then brushed. The beaters 19, 20 may be modified by the provision of air or water blasts instead of breast plates.

Abstract: 1,061,728. Methods and materials for making photographic images. EASTMAN KODAKCO. Sept.11, 1963 [Sept.11, 1962], No.35801/63. Heading G2C. Relief images are produced by image-wise exposing an unhardened silver halide emulsion containing iron, cobalt or nickel particles, developing so as to differentially harden or soften the emulsion and then subjecting the emulsion to a magnetic field so that the softer portions are removed to leave a relief image in the emulsion. Before subjecting to a magnetic field, the differentially hardened or softened layer may be contacted with a receptor sheet so that a relief image is also obtained on the receptor sheet after subjection to a magnetic field. The preferred method is to image-wise expose a gelatino-silver halide emulsion containing unhardened gelatine, a tanning developer, (e.g. 4-phenyl catechol) and carbonyl iron powder, develop in an alkaline solution to obtain differential hardening, pass the developed emulsion across the pole of the magnet so that the unhardened gelatine is removed to the magnet or to a receptor sheet. Either of the relief images obtained may be coated with magnetic ink and used as a printing plate. Alternatively, the exposed and developed silver halide emulsion layer may be treated with an etch bleach bath which oxidizes the silver and degrades the gelatine and degraded areas may then be removed.
