Title: Process for preparing dyeings and prints fast to wetting on cellulosic materials
IPC: C09B62/78
Filed: 1964-08-20
Abstract: Cellulosic materials are dyed with dyes containing at least one water soluble group e.g. sulphonic or carboxylic acid groups and at least one group of the general formula <FORM:1034876/D1-D2/1> in which R and R1 each represent an alkyl, cycloalkyl, aralkyl or aryl radical which may carry other substituents e.g. halogen, alkyl, alkoxy, nitro, sulphonic or carboxylic acid groups, the dye being applied at elevated temperatures in the presence of an alkaline reagent.  The dye may be of the mono-dis- or polyazo type or anthraquinone or phthalocyanine types and may have more than one group of the formula above.  The dye fixation is advantageously carried out by steaming at 98-103 DEG C. or by a dry heat treatment at 130-190 DEG C.  The cellulosic material may be printed with a paste containing the dyestuff or impregnated with a solution of the dye before fixation. Blue, red, yellow, and grey colours are obtained.

Abstract: 495,519. Theft alarms. BRENDLER, SEN., K. Dec. 14, 1937, No. 34593. Convention date, June 2. [Class 118 (i)] [Also in Group XXXI] To guard against unauthorized use of a motor vehicle, a frangible container charged with a fluid giving off an irritant gas, such as sulphuretted hydrogen or brom-acetone, is arranged in the vehicle so that it will be fractured if some normal starting operation is performed while the vehicle is in a locked condition, the container being protected from fracture when the vehicle is unlocked and in normal use.

Title: A process for intensifying and supplementing the flavours of dairy products
Inventor: HORI SHIRO
IPC: A23L27/24
Filed: 1964-08-25
Abstract: Enzymes are derived from microorganisms of the genus Trametes In an example, Trametes sanguinea (L. ex Fr.) Lloyd (ATCC-14622) was inoculated on a sterile aqueous medium containing: sucrose-4%, glucose-2%, soyabean cake-3%, cornsteep liquor-1%, ammonium sulphate-0.2%, potassium dihydrogen phosphate-0.2%, magnesium sulphate heptahydrate-0.1%, copper sulphate-0.05%.  Incubation was effected at 28 DEG  C. for 140 hours with agitation and aeration. The pH was adjusted to 4.0 by ammonium sulphate, the broth was filtered, and crude enzyme was precipitated from the filtrate by ammonium sulphate, collected by centrifuging, and dried at 35 DEG  C. The crude enzyme was then dissolved in distilled water, dialysed at 4 DEG  C. for a day, and reprecipitated with ammonium sulphate.ALSO:Improved dairy products are obtained by treating a starting material comprising milk, or a product prepared or being prepared therefrom, with a flavouring enzyme produced by micro-organisms of the genus Trametes, especially Trametes sanguinea (L. ex Fr.) Lloyd (ATCC-14622).  Suitable starting materials include cow's milk, skim milk, cream, butter, condensed milk, green cheese, or a sour milk beverage such as yoghurt.  If desired the enzyme may be produced in situ by adding the microorganism to the starting material.  In examples the enzyme was used in place of the conventional starter and rennet to prepare a cheese without ripening, and in the preparation of butter from cream, and a flavoured milk was prepared by inoculating cow's milk with the Trametes.

Patent GB-810542-A (GB)
Title: Recovery of protoactinium
IPC: C01G99/00
Filed: 1945-12-21
Abstract: The protoactinium isotope of atomic weight 233 is adsorbed from aqueous solution by contacting the solution with a cation exchange resin having sulphonic acid groups at the cation exchange positions. The resin is preferably a sulphonated phenolformaldehyde condensation product.  To form the solution treated, thorium in the metallic state, or as an oxide or carbonate, is exposed to slow neutrons. Moderating material, e.g. graphite, paraffin or deuterium oxide, may be interposed between fast neutrons and the thorium, or may be mixed with the thorium; alternatively an hydrated thorium hydroxide may be used.  The neutrons may arise from a chain reacting mass which contains uranium or plutonium.  The irradiated thorium is dissolved in nitric, sulphuric, or hydrochloric acid, and the solution may be heated to deposit a siliceous precipitate which is removed. Contact with the resin is suitably effected by passing the solution through a column of the resin which is then washed with acid and water, and the protoactinium eluted with an aqueous solution of ammonium fluoride or hydrogen fluoride.  Before carrying out the adsorption, a solution of manganese nitrate may be added followed by potassium permanganate solution to form a precipitate of manganese dioxide which carries down the protoactinium; the precipitate is dissolved in nitric acid containing a reducing agent, e.g. hydrogen peroxide.  The reducing agent may be removed and the manganese dioxide precipitation repeated.  Precipitation by means of manganese dioxide may also be carried out on the fluoride solution which has been used to elute protoactinium from the adsorbent.  The final solution containing Pa233 is allowed to decay and the U233 formed is extracted with ether, returned to water solution, and the uranium precipitated as ammonium uranate, uranium peroxide, or by means of acridine hydrochloride and thiocyanates.
