Patent GB-221228-A (GB)
IPC: F16C37/00
Filed: 1924-08-30
Abstract: 221,228. Kook, O. Aug. 31, 1923, [Convention date]. Cooling bearings; dust, excluding; oil, catching and removing. - Vane - wheels arranged in air or gas currents, for use as spark extinguishers on locomotives, are supported on ball bearings upon a vertical shaft and tight-fitting heatprotecting covers for the bosses of the vanewheels are provided in combination with a cooling circuit. A hollow axle 1 is supported in a chimney by cross arms 2, 3 and carries blade wheels 4, 5 adapted to be rotated in opposite directions by the gas current. The wheels 4, 5 are secured to flanges on members 6, 7 respectively containing ball bearing rings 8, 9 and having screwed thereon hollow covers 10, 11 and 10, 12 filled with asbestos &c. The bottom cover 12 has a conical closed bottom to receive the oil from the bearings whilst the cover 11 has a projecting edge engaging in an annular groove in a tightening member 13 secured to the axle 1. The covers 10 have their free edges bent downwardly to engage in annular grooves in tightening members 14 protected by rings 15. An oil tube 16 inserted in the axle 1 has branches communicating with annular !grooves 17 in the members 14, which, in turn, communicate by passages with the outer space containing the ball bearings. The upper bearing ring 9 is axially extended into a bearing ring 18 from which the oil is led by passages to the interior of the axle 1 so as to join the oil coming from the member 7 into the cover 12 from which oil suction tube 20, Fig. 2, in the axle 1 is attached to the outlet 18, Fig. 1, and passes through a. nut 21 closing the axle 1 to the oil receiver. The axle 1 can then be further cooled by supplying air or water to it through a tube 22, an outlet casing 23 having an outlet tube 24 being secured to the upper part of the axle 1, in which case, the quantity of oil fed to the bearings can be reduced and the residue of oil can be extracted by removing the cover 12, although a tube 25 extending from the oil receiver through the nut 21 and axle 1 to a sucking device may be employed, if desired. If air is used as the cooling medium, the apparatus may be simplified by dispensing with the tube 20, nut 21, tube 24 and the upper part of the tube 16, the latter being bent to the side of the casing 23 with an open mouth. In this case, the air entering the lower part of the axle 1 is mixed with the oil and the mixture passing upwards is cooled by the air; the oil then falls again through the pipe 16 to the bearings after being separated from the air, which is exhausted through an opening in the top of the casing 23. Additional cooling by water or air can also be obtained in the construction shown in Fig. 1 by inserting a U-shaped or coiled cooling pipe in the axle 1.

Title: Improvements in or relating to methods of separating uranium from thorium and protactinium
IPC: C22B60/02
Filed: 1946-07-09
Abstract: Uranium is separated from thorium and protactinium by adding to an aqueous solution of their salts an organic salt of the formula <FORM:0809282/III/1> wherein R is alkyl, R1 is alkyl or aryl, and M is an alkali metal or alkaline earth metal.  The corresponding organic uranyl compound is formed and is extracted from the aqueous solution.  In a preferred procedure, thorium carbonate which has been irradiated with neutrons and contains small amounts of uranium and protactinium, is dissolved in nitric acid, brought to a pH of 2-3 by addition of ammonia, and then shaken with a solution of sodium diethyldithiocarbamate in amyl acetate.  Uranyl diethyldithiocarbamate forms and dissolves in the organic layer. This layer is separated and uranium may be recovered therefrom by evaporating the solvent, heating the residue to form uranium oxide, dissolving this in acid, and removing thorium by precipitation as fluoride.  Other suitable organic solvents are methyl isobutyl ketone, diethyl ketone, methyl n-propyl ketone, and dibutoxytetraethylene glycol.  Before treatment with the organic salt solution, protactinium may be removed from the nitrate solution by adsorption on manganese dioxide.ALSO:In the separation of uranium from thorium and protactinium (see Group III), an aqueous solution of their salts is reacted with an organic salt of the formula <FORM:0809282/IV (b)/1> wherein R is alkyl, R1 is alkyl or aryl, and M is an alkali metal or alkaline earth metal.  The corresponding organic uranyl salt, e.g. uranyl diethyldithiocarbamate, is formed and is extracted with a water-immiscible organic solvent, e.g. amyl acetate.

Title: A process for preparing membranes selectively permeable to cations
IPC: C08J5/22
Filed: 1955-07-19
Abstract: Cation permselective membranes are prepared by sulphonating films comprising one or more copolymers of aromatic mono-vinyl compounds with at least 20 per cent by weight of linear aliphatic polyene hydrocarbons.  Specified mono-vinyl compounds are styrene, vinyltoluene, vinylxylene, ethyl styrene and diethyl styrene. Specified polyene hydrocarbons are butadiene and isoprene. Mixtures of the copolymers with other polymers, e.g. styreneacrylonitrile copolymers, and natural rubber may be used. Films may be formed by rolling or by casting a benzene, toluene or xylene solution of the copolymers on mercury or a glass plate coated with silicone grease. The films may be vulcanized by incorporating vulcanizing ingredients, e.g. sulphur, mercaptobenzothiazole, stearic acid and zinc oxide, prior to rolling and then heating the film.  Alternatively the films may be treated with sulphur chloride alone or in solution, e.g. in tetrachlorethane.  Sulphonation may be effected by immersing the films in concentrated sulphuric acid, oleum or chlorosulphonic acid, preferably at temperatures not above 50 DEG  C.  Preferably the film is immersed in concentrated sulphuric acid, oleum added at intervals, and the product immersed in successively diluted sulphuric acid and finally rinsed with water.

Abstract: 441,403. Driving dynamos. LUCAS, Ltd., J., and MASON, S. A., Great King Street, Birmingham. July 20, 1934, No. 21307. [Class 35] A cycle dynamo pivotally supported on a spindle passing into or through one end of the dynamo body with a spring surrounding the enclosed part of the spindle, has means carried by the spindle for preventing movement of the dynamo into the operative position, and the arrangement is such that the relative movement between the said means and the dynamo, or a part carried thereby, for permitting the dynamo to move towards its operative position can be effected without varying the angular position of the dynamo on the spindle. In the form shown, the dynamo is held in its inoperative position by the engagement of a pawl t on a lever s pivoted on the dynamo body with a shoulder q on a catch plate p secured to one end of the spindle e. It is released from this position by moving a lever s against the action of a spring u to permit the spring h to swing the dynamo. In a modified form, a pin passing through the spindle projects into an L-shaped slot on a member secured to the dynamo body and the dynamo is moved in the axial direction of the spindle to inaugurate its movement to the operative position.
