Title: Process for the reduction of uranium hexafluoride to uranium tetrafluoride
IPC: C01G43/06
Filed: 1963-08-09
Abstract: Uranium tetrafluoride, UF4, is produced by reduction of uranium hexafluoride, UF6, with PF3 or PF3 + HF in the gaseous phase at a temperature less than 150 DEG  C., particularly less than 350 DEG  C. The intermediate fluorides UF5, U4F9, U4F17, if produced, disproportionate on heating at a temperature from 100-300 DEG  C. in the absence or presence of PF3, and UF6 thus produced is recycled and reduced with PF3.  Excess PF3 is removed by reaction with water; UF4 is recovered as a green insoluble solid.  The ratio of PF3 to UF6 is preferably greater than 1; if HF is used the PF3 to HF ratio is preferably between 1 : 1 and 1 : 20. In an example, the colourless uranium hexafluoride and phosphorus trifluoride were allowed to warm together from liquid nitrogen temperature, the mixture turning brown and green. On heating to 200 DEG  C. and then to 350 DEG  C. the solid turned dark green as the intermediate fluorides disproportionated forming UF4.  The solid residue was treated with NaOH which dissolved all solids except the green crystalline insoluble UF4, and the latter was separated and identified.

Patent GB-674195-A (GB)
Title: Improvements relating to human hair waving and human hair removing preparations
IPC: A61K8/46
Filed: 1949-12-12
Abstract: Human-hair waving preparations containing one or more water-soluble salts of mercaptans or of carboxylic thio acids containing one or more SH groups (particularly of thioglycollic acid) have incorporated in them prior to use one or more metal ammine salts which are soluble in ammoniacal solutions but of which the corresponding metal sulphides are insoluble or only sparingly soluble in water, which ammine salts are reactive with hydrogen sulphide at room temperatures.  Examples of suitable ammine salts are water-soluble salts of cupro-tetrammine, cadmium-tetrammine, zinc-tetrammine and cobalt-hexammine and complex nickel-ammine salts, zinc-tetrammine being preferred owing to its low toxicity.  The proportion of metal ammine salt present in the preparation may range from 0.1 per cent by weight up to the maximum which can be dissolved in the preparation. An example is furnished of a cold wave lotion containing 6.0 per cent by weight of ammonium thioglycollate and 2.0 per cent of ammonia (calculated as NH3), with which is incorporated 3.0 per cent of zinc-tetrammine sulphate and sufficient water to make 100 per cent. In another example a hair-waving solution also intended for use at room temperature contains 5 per cent by weight of the ammonium salt of alpha-mono-thioglycerol, 2.0 per cent of ammonia (calculated as NH3), with which is incorporated 3.0 per cent of zinc-tetrammine sulphate and sufficient water to make 100 per cent.  The hydrogen sulphide generated by the reaction with the hair of the thioglycollate or other active ingredient of the preparations converts the ammine salt also present into the corresponding metal sulphide, and the unpleasant odour which would otherwise result during the use of the preparations is thus prevented.

Title: Improvements in or relating to the production of play balls
IPC: B29C65/00
Filed: 1933-11-16
Abstract: 419,482. Game balls. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey, TWISS, D. F., and McCOWAN, W., Fort Dunlop, Birmingham. Nov. 16, 1933, No. 31910. [Class 132 (ii).] Game balls, for example tennis balls, are made by depositing a liquid composition on a preferably spherical former to form a relatively thin elastic nucleus. After removal from the former, the aperture in the nucleus is closed, a coating of rubber is applied and the whole is vulcanized in a spherical mould. Finally the usual felt cover is added. Aqueous emulsions or dispersions of rubber are preferably used for both the nucleus and subsequent coating, and may consist of rubber, guttapercha, balata or similar vegetable resins. The nucleus may be removed from the former by stretching or the former may be of material which can readily be rendered plastic or liquid. The aperture in the nucleus may be sealed by tying, or by securing a cap thereover by rubber solution or latex, and the subsequent coating may be applied (1) by cupping, the operation being expedited by the use of a coagulant or otherwise (2) by winding with unvulcanized rubber tape produced by calendering or spreading. Inflating agents may be introduced into the nucleus before it is sealed, or subsequently at any stage by the hollow needle method in which case a rubber plug is secured to the inside of the nucleus. Preferably, agents are also introduced into the nucleus before closing for increasing the permeability of the rubber ball, and are spread to form a uniform lining before or after sealing of the nucleus. In one example the nucleus is formed by dipping a former into a compounded latex dispersion comprising rubber 92 parts, sulphur 2, zinc oxide 1, mineral oil 4 and accelerator 1 part, and then vulcanizing the dried deposit. The inside of the nucleus is covered with impermeable dope, for example, as described in Specification 416,679, [Group V], inflating agents are introduced, and a cap is secured over the aperture by a rubber or latex cement which vulcanizes at ordinary temperatures. The outside of the sealed nucleus is then coated with dope and allowed to stand, after which the winding or cupping operation is effected. Specifications 219,635 and 290,313, [both in Class 70], also are referred to.
