Title: Improvements in or relating to quick-cooking rice
IPC: A23L7/196
Filed: 1954-04-27
Abstract: In preparing quick-cooking rice, dehulled rice is treated with water and heated to bring its moisture content progressively to between 60 and 75 per cent by weight, the amount of water being limited to that which the rice can absorb at the temperature of treatment.  The treatment may comprise passing the rice through a series of water sprays of progressively increasing temperature until it attains a temperature of about 100 DEG C.  The rice should, preferably, acquire a moisture content of about 30 per cent before gelatinization temperature (about 65 DEG C.) is passed.  The rice may be sprayed with water at room temperature, then with hot water and/or steam to bring its temperature to about 100 DEG C. and then with hot or cold water to bring its moisture content to between 60 and 75 per cent. Before being sprayed with hot water and/or steam, the rice may be steeped in or sprayed with hot water at a temperature between 60 and 100 DEG C. to remove fatty material. Initially, the rice may be flash-steamed and then subjected to flash treatment with a fat-dissolving solvent, e.g. hexane or pentane.  The moistened and gelatinized rice may be compressed mechanically, e.g. between rollers or rigid surfaces.  It may be frozen and/or dried to a moisture content between 10 and 14 per cent.  Quick-cooking rice having a specific gravity of 0,48 may be produced from rice having a specific gravity of 0,85.

Filed: 1972-03-17
Abstract: 1340445 Reforming hydrocarbons TEXACO DEVELOPMENT CORP 17 March 1972 [18 May 1971] 12576/72 Heading C5E A hydrocarbon conversion process comprises contacting a paraffin hydrocarbon of six or more carbon atoms with hydrogen, a fluorided catalyst of a metal of Group VIIa or VIII on alumina, and water amounting to 3 x 10<SP>-5</SP> to 5 x 10<SP>-4</SP> gram-mole per hour per gram of catalyst. The water may be added as such or formed in situ by the hydrogenation of organic oxygen compounds added to the feed. The alumina of the catalyst may contain silica, thoria-alumina, zirconia-alumina or titania-alumina. The presence of the water reduces or suppresses the cracking activity of the catalyst, but not the isomerization activity, but the effect can be reversed by discontinuing the addition of water. The addition of water may be continuous or intermittent. In Examples 1 and 2, the feed is a mixture of normal hydrocarbons of from 10 to 14 carbon atoms, which are isomerized with little cracking. In Example 3 the feed is similar but contains also toluene; the product contains a corresponding amount of naphthenes. Other feeds referred to range from hexane to residual oils and include slack waxes; the products include oils of high viscosity index.

Filed: 1973-03-16
Abstract: 1401942 Measuring components present in a gas CHRYSLER CORP 16 March 1973 12685/73 Heading G1A In a spectrophotometer for measuring the amounts of a number of components (e.g. carbon dioxide, water vapour, &c.) present in a gas mixture (e.g. automobile exhaust), infrared radiation passing through a sample cell 15, through which the gas mixture flows, is received by a detector 30 after it has passed through a one of a number of filters 72, or 73, including a reference filter and filters sensitive to the components of interest, on a rotating disc 71 which also contains an opaque portion designed to cut off the radiation from the source 12 so that the detector substantially only receives the background radiation. The detector's output signals corresponding to the background reference and components are stored sequential by sample and hold circuits controlled by sychronizing means such as provided by small holes in the periphery of the disc Figs.9-13 (not shown), passing between an elongated source and a plurality of detectors, Fig.13. The stored signals are then processed by compensating the reference and component signals for background radition and then dividing each background compensated component signal by the background compensated reference signal to produce a ratio signal, for each component being investigated, representative of the amount present in the gas mixture. The description discloses processing circuits Figs. 15-19 (not shown), for the detector output signals and discusses at length the mathematics behind the signal processing and the errors involved. In one processing circuit, Fig.17 (not shown), each component signal after being compensated for background radiation and "divided" by the reference signal is compensated for any interference or error due to water vapour components present in the gas mixture. This extra compensation is further developed, Figs.17 and 18 (not shown), in further circuits where each component is compensated for the effects of interference from all the other components present in the gas. The description discloses ways of calibrating the circuits.
