Patent GB-469334-A (GB)
Title: Manufacture of washing preparations
IPC: C11D1/72
Filed: 1936-01-27
Abstract: A powdered distributable washing-composition consists of a polyglycerol or polyglycol ether in admixture with a calcined salt obtained by heating an alkali salt of a mineral acid with escape of a gaseous component such as water or carbon dioxide.  The ethers are represented by the formula R1.R.X.(ZO)n.Z1.OH, in which R is an aliphatic or isocyclic radical; R1 is hydrogen or an aliphatic radical; X is O, <FORM:0469334/III/1> (where R2 is an aliphatic radical); Z is CH2.CH2, <FORM:0469334/III/2> same as Z; and n is greater than 1.  Such compounds are obtained by treating fatty alcohols, fatty acids, fats, waxes, resins, phenols, naphthols, amines, ethanolamides with ethylene, propylene, or butylene oxides. Suitable calcined salts are, sodium or potassium carbonate (obtained by calcining the bicarbonate), sodium pyrophosphate (from disodium phosphate), sodium sulphate (from Glauber's salt) or sodium borate (from borax).  The heat treatment results in the formation of hollow pores in the salt which thereby have absorbing properties similar to kieselguhr.  In examples, the reaction products of (1) iso-octyl phenol and ethylene oxide; (2) dodecyl alcohol and propylene oxide; (3) ricinoleic acid and ethylene oxide; (4) oleic acid ethanolamide and ethylene oxide; (5) a primary amine obtained by hydrogenating a mixture of nitriles obtained from coconut-oil fatty acids and ethylene oxide; (6) dodecyl phenol or abietinic acid with ethylene and butylene oxide or (7) tall oil and polyglycerol, are mixed with the calcined salts.  Other (non-calcined) salts which may be added are, sodium perborate, sodium chloride, magnesium sulphate, sodium metaphosphate, potassium sulphate or percarbonate.  The ethers and crystalline salts may be mixed together and subsequently dehydrated and calcined.

Abstract: 869,561. Vacuum furnaces. STAUFFER CHEMICAL CO. Jan. 26, 1960 [May 14, 1959], No. 2768/60. Class 51 (2). [Also in Groups XXII and XL (a)] Melting stock 23 is continuously advanced along a substantially horizontal path lying above a mould 16 into the open end of which a high voltage electron beam is focused, the stock being melted by said beam without interrupting the bombardment of the mould, and a region encompassing the open mould and the melting end of the stock being evacuated.

Abstract: 789,454. Coating webs. BRITISH CELLOPHANE, Ltd. Feb. 1, 1956 [Feb. 4, 1955], No. 3370/55. Drawings to Specification. Class 140. Apparatus for applying a coating to a film by the process described in Specification 663,645, consists of a pair of rollers forming a nip, which rollers are provided at each end with a pair of similar co-operating frustoconical members (" conical tyres ") maintained in contact by pressure, both conical tyres of each roller tapering in the same direction, and means for axially moving the rollers relative to one another in order to adjust the gap between them. The larger diameter of the tyre at one end of the roller and the smaller diameter of the tyre at the other end may be equal to that of the barrel. Errors of parallelism may be corrected by moving a conical tyre axially relative to the barrel. The tyres may be formed integral with the barrel, e.g. by mounting the roller and trunnions in a cylindrical grinding machine and forming the conical tyres and grinding the barrel in one operation, without disturbing the position of the roller as a whole, or they may be separate units mounted on the ends of the barrel which are reduced in diameter to receive them. The pressure applied to maintain contact of the rollers may be mechanical, pneumatic or hydraulic. It may be variable in amount and may be applied to the bearing housings or to the tyres themselves. The rollers may be driven so that the peripheral speed of each barrel is equal to the speed of forward travel of the material being coated, so that one of the barrels is driven and the other is driven frictionally through the tyres, or both rollers may be freely mounted and turned by the moment exerted by the material being coated. Axial movement of the rollers with respect to each other may be achieved by a screw thread adjustment system moving fixed collars on the spindle of each barrel. A guard chamber fitted for supply of filtered dry air at pressure above atmospheric may cover the tyred portions of the rollers. The material produced may be used as moisture proof sheet wrapping material, e.g. regenerated cellulose film coated with vinylidene chloride copolymers. The material to be coated may be passed through the nip, round a series of rollers and then back into the nip.
