Title: Rapid manufacture of cheese
IPC: A23C19/06
Filed: 1965-10-18
Abstract: A process for ripening cheese comprises incorporating the cheese in a fluid system to form a liquid suspension containing 9-50 wt. per cent. solids, with the remainder substantially water, and then agitating until the cheese is ripe.  The ripened cheese may be recovered by removing at least part of the water, for example by spray or roller drying.  The agitation may be effected under either aerobic or anaerobic conditions, preferably for 1-10 days.  The unripened cheese may have been formed in situ, for example by introducing a cheddar cheese inoculum into sterilized milk or a suspension of a coagulated protein in water.

Title: Improvements in and relating to polyester resins
Inventor: ROWE RICHARD
IPC: C08G63/48
Filed: 1963-11-09
Abstract: The invention comprises an alkyd resin derived from castor oil or castor oil fatty acids, a dimeric acid and a polyhydric alcohol.  The dimeric acid is the product of polymerization of an unsaturated fatty acid or conjugated poly-unsaturated fatty acid or mixture thereof. The products of polymerization of mixture rich in linoleic acid (e.g. containing 30-70% thereof) are particularly suitable.  The dimeric acid may be replaced up to 50% by other dicarboxylic acids, e.g. adipic, succinic, azelaic and sebacic acids.  A suitable polyhydric alcohol is glycerol.  The resin may be mixed, as plasticizer, with nitrocellulose, ethylcellulose, urea-formaldehyde or melamine-formaldehyde resins in surface coating compositions.  In the examples castor oil fatty acids and glycerol are condensed with a dimeric acid or dimeric acid/adipic acid mixture, and the product alkyds are mixed with urea-formaldehyde resin in xylol, and with solutions of nitrocellulose in methyl isobutyl ketone and ethylcellulose in 80/20 xylene/butanol to give lacquers.ALSO:A burnished steel plate is coated with (1) a solution in xylol of 10 p.b.w. of a castor oil fatty acid/dimerized fatty acid/glycerol alkyd and 40 p.b.w. of a urea-formaldehyde resin or a solution in methyl isobutyl ketone of nitrocellulose containing 10-35 wt.% (total solids) of the same alkyd; (2) a solution in methyl isobutyl ketone of 10 p.b.w. nitrocellulose and 2.5 p.b.w. of an adipic acid/castor oil fatty acid/dimerized fatty acid/glycerol alkyd or a solution in 80:20 xylene/butanol of 10 p.b.w. ethylcellulose and 3.3 p.b.w. of the same alkyd.

Title: Method for producing carbon structures from molten baked substances
IPC: D01F9/21
Filed: 1964-10-30
Abstract: Carbon filaments and films are obtained by melt extrusion and stretching a molten material obtained by baking at from 300 DEG  to 500 DEG  C., a natural or synthetic organic substance which will produce the molten material as a result of baking.  Extrusion takes place at a temperature between room temperature and the baking temperature.  The resultant material is subjected to oxidation treatment in an oxidizing gas at a temperature between room temperature and the extrusion temperature followed by carbonization at a temperature above 500 DEG  C.  The oxidation treatment may be carried out with ozone or oxygen gas at a temperature at which it will not melt or adhere (e.g. 25-100 DEG  C.), followed by heating (e.g. at 260 DEG  C.) in an oxidizing gas such as air.  The organic material may be polyvinyl chloride.
Patent GB-449757-A (GB)
Abstract: 449,757. Cash registers &c. MITCHELL, K. A., 273, Mount Pleasant Road, Tottenham, London. Dec. 28, 1934, No. 37140. [Class 100 (iv)] [See also Group XIX] Index setting-arrangements.-Relates to means of the differentially movable slide or dial type for setting and operating cash registers or calculating-machines. As shown, each setting slide A is of inverted U-shape and carries a series of finger pieces b. The space between each pair of adjacent finger pieces is normally filled in by a plunger a carrying a symbol and pressed outwardly by a spring. The machine is operated by depressing the appropriate plunger and moving the slide down until a type bar i on the plunger is arrested by a platen g. As it nears the platen the stem of the depressed plunger engages and carries with it a numbering or dating stamp. The items are printed on a record strip and, if desired, on an inserted slip or issued voucher, and means may be provided for viewing and making autographic notes on the record strip. Certain items may be printed in a distinctive colour by means of a bi-coloured ribbon, the ribbon being shiftable laterally or the plunger provided with spaced sets of type. The record material may be perforated instead of printed. In the event of two or more plungers being placed side by side on the slide, the plunger stems are stepped to render the movement of the slide proportional to the amount entered. The depression of a plunger may serve to release or operate other mechanisms by carrying with it a plate attached to a spring-controlled rod m, Fig. 5, which may have a rack r for operating adding mechanism. Or a rack might be attached to the backplate l to operate registering pinions.
