Abstract: 529,550. Securing articles on shafts; friction clutches; brakes for cycles &c. SODERQVIST, W. O. N. June 2, 1939, No. 16335. Convention date, June 4, 1938. [Class 80 (ii)] [Also in Groups XXXI and XXXIV] A clamping or coupling element, applicable as a friction clutch or brake, consists of a sleeve divided longitudinally into an even number of elements 3, 4, 5, 6 tapering longitudinally in opposite directions, the adjacent edges a, b, c, d being chamfered, so that axial displacement of alternate elements 4, 6 relative to the remaining elements 3, 5 will force the elements 3, 5 radially outwards and elements 4, 6 radially inwards by the wedging actions of the chamfered edges. As shown, the device is used to secure a ballbearing race on the shaft 1 ; the parts are locked in engagement by a split ring 7 engaging a groove in each of the elements 3-6. When used as a clutch or brake, one set of elements is provided with keys or the like for ,preventing their rotary or axial displacement on the shaft, and the remaining elements are provided with end flanges engaged by a socket displaceable on the shaft by means of a lever &c. When used as a brake and coupling in a free-wheel hub for bicycles, the displacement of the sleeve elements is effected by inclined surfaces on the sprocket rim, in opposition to springs tending to effect disengagement.

Inventor: CAMPBELL DONALD ROBERT IVAR
IPC: A23L17/00
Filed: 1950-06-30
Abstract: Fish, e.g. herrings, sprats, pilchards, are cooked, comminuted and mixed with flour to form a batter, water, milk or other edible liquid being added if required, and the batter is then cooked in thin layers.  The edible liquid may be tinned milk or cream, fruit juice or vegetable juice.  Up to 50 per cent by weight of cooked potatoes may be added to the batter which may be flavoured e.g. with anchovy. The fish, gutted but complete with bones, may be pressure-cooked e.g. at 15 lb. per sq. in. for about one hour. Wafers may be produced by dipping a tool e.g. a waffle iron, into the batter and then into hot fat or oil e.g. thin cooking oil at temperatures between 375 DEG F and 385 DEG F, or by cooking the batter on a waffle plate.  The wafers may be centrifguged e.g. in a heated centrifuge, to remove surplus fat or oil.

Title: Improvements in the production of thickened lubricating oil compositions
Inventor: CARSWELL WILLIAM DAVID
Filed: 1958-05-27
Abstract: Thickened lubricating oils and lubricating greases are prepared by gradually adding a gel of an inorganic gel material in a volatile organic liquid to a hot lubricating oil and maintaining the oil at an elevated temperature during the addition so that the organic liquid rapidly evaporates.  The inorganic gel material may be a metallic oxide, hydroxide, sulphide, silicate, sulphate or carbonate or a mixture of such substances.  Silica may also be employed, especially in admixture with alkaline earth metal hydroxides.  The volatile organic liquid may be an alcohol (e.g. ethyl alcohol, the propyl alcohols, diacetone alcohol, cyclohexanol or methyl cyclohexanol), a ketone (e.g. acetone, diethyl ketone or methyl ethyl ketone), an ether (e.g. isopropyl ether or dioxane), an ester (e.g. methyl or ethyl acetate), a diol (e.g. propylene, butylene or hexylene glycol), a diglycol (e.g. dipropylene or dibutylene glycol), a glycol monoalkyl ether, a glycerine mono- or di-alkyl ether, an amine (e.g. an alkanolamine) or a heterocyclic base (e.g. pyridine or morpholine).  Volatile hydrocarbons are also mentioned but are not preferred.  The lubricating oil may be a mineral oil (e.g. bright stock) or a synthetic oil or a mixture of both.  Synthetic oils mentioned are esters of aliphatic dicarboxylic acids (e.g. dialkyl sebacates or adipates), polyoxyalkylene compounds (e.g. polyglycols or alkylene oxide polymers) and polysiloxanes.  Antioxidants (e.g. phenyl alpha- or beta-naphthylamine) and surface-active agents may also be present.  The surface-active agent may be cationic, anionic or non-ionic.  Cationic surface-active agents mentioned are salts (e.g. halides or acetates) of organic ammonium, phosphonium, sulphonium arsonium or stibonium bases, and especially amine salts, salts of heterocyclic nitrogen compounds and quaternary ammonium salts; also amines, amido-amines and partial amides derived from acrolein/ammonia, halohydrin/ammonia or halohydrin/amine condensation products.  Anionic surface-active agents mentioned are fatty acids or their soaps.  If desired, the particles of the gel material may be coated with an esterifying or polymerizable silicon compound, such as an alkyl halo silane, an alkyl alkoxy silane or an alkoxy amino silane.  The polymerizable silicon compound may be polymerized in the presence of the gel material.  The removal of the volatile organic liquid from the hot lubricating oil by evaporation need not be complete and the thickened lubricating oil or lubricating grease may be subjected to milling or shearing.  In examples, lubricating greases are prepared from (a) silica gel in isopropyl alcohol, stearic acid partial amide of epichlorhydrin/ammonia condensate, phenyl beta-naphthylamine and hot mineral oil or hot dioctyl sebacate, polymethyl phenyl siloxane also being added in one instance; or (b) silica gel in petroleum spirit, dimethyl diethoxy silane and hot mineral oil.
