Abstract: 1,211,578. Roller bearings. NADELLA and A. PINTER. 1 Feb., 1968 [10 Feb., 1967; 12 Sept., 1967], No. 5215/68. Heading F2A. A roller bearing assembly for fixing in at least one direction the axial position of one machine element 1 relative to another 8 comprises needles 3 radially guided by two raceways which are fixed or formed on the respective machine elements, the needles being circumferentially guided by a cage 11 and having opposite ends abutting two radial faces 2, 4 which are fixed with respect to the respective raceways thereby fixing the relative axial position of the machine elements in at least one direction. Two such assemblies may be used to prevent axial displacement in both directions of an element, such as a shaft having a double shoulder (Fig. 10, not shown), by arranging each assembly to exert its retaining action in opposing directions. The double shoulder on the shaft may be replaced by annular washers (Fig. 12, not shown) which are joined in such a manner as to counteract the expansion in the shaft and the connectors between the washers during operation in order that the distance between the washers on which the rollers bear is not changed.

Title: Method of treating whale meat for storage and transport
IPC: A23B4/02
Filed: 1929-02-16
Abstract: 333,898. Hansen, D. A. Jan. 28, 1929, [Convention date]. Void [Published under Sect. 91 of the Acts]. Preserving whale &c. meat.-Whale and othei kinds of meat are preserved by treatment with a dilute solution containing sodium biborate and boric acid. Preferably the solution contains a comparatively small proportion of boric acid. The solution is preferably produced from boric acid and borax under such conditions and so shortly before use that the formation of polyborates takes place while the solution is in contact with the meat. Other preservatives may be added to the solution. The whale meat may be treated by brushing with, dipping into or immersion in, the solution which may be weak, for example 0.5-1 per cent, and may be prepared by using fresh or sea water. In an example, fresh whale meat is cut into pieces which are immersed for some time in a solution containing 4.5 gm. boric acid, 5 gm. sodium biborate, and 0.5 gm. salicylic acid to one litre of water. The meat is then packed &c. for transport or storage. Before distribution for consumption it can be freed from the greater part of the preservatives by washing in fresh or sea water; the washing can be omitted when very dilute solutions are used. Another solution which may be employed contains about one per cent of sodium biborate and 0.5 per cent of boric acid.

Abstract: 457,267. Spring motors. BROWN, E. C., 84, Sinclair Road, West Kensington, and HENLEY, A. M., 307, Goldhawk Road, Shepherd's Bush, both in London. Feb. 19, 1935, No. 5319. [Class 10] [See also Group XXXVIII] A gramophone motor of the kind which is wound by pulling out a cord comprises a disc E around the periphery of which the cord D is arranged and to which it is attached, the disc being mounted on a spindle E<1> which turns with it and tensions one or more longitudinallyextensible springs F, F<1>, which then rotate the spindle E<1> and cause it to rotate the turntable through gearing (not shown). A freewheel device in the gearing transmits the drive to the turntable only when the spindle is rotated by the springs. In the motor shown, the ends of the springs are attached to flexible wires f<1> secured to and wound around the spindle E<1>. The cord D passes through a rubber member D<2> which holds it frictionally to retain it in the groove formed in the edge of the disc E. Fig. 3 shows a construction in which the cord is rewound on the disc immediately after it has been pulled out, the disc being threaded on to the spindle E<1> so that it falls by its own weight when the cord has been withdrawn and simultaneously rotates so as to re-wind the cord on it. During operation of the motor the rotation of the spindle returns the disc to its upper position in readiness for the next re-winding of the motor.

Abstract: 1464530 Mineral purification HOGANAS AB 7 Feb 1975 [14 March 1974] 5428/75 Heading C1A A mineral having a laminar structure is purified by (1) forming a slurry in water of the mineral with a particle size no greater than 44 microns, (2) treating the slurry with an ozonized gas to delaminate the particles, and thus to release foreign mineral particles enclosed between the laminµ of the mineral and (3) removing the foreign mineral particles from the slurry. In the example, kaolin is slurried in water in container (I) using stirrer (2). After passing through a sieve (3), the #44 micron slurry was treated with a melting agent (usually sodium hexametaphosphate) through conduit (4), and then passed to a lamella separator (5), which contains a plurality of inclined partition walls. The slurry flows upwards between these partition walls, while the heavier foreign mineral particles move downwards and are removed via outlet (6). The partially purified kaolin slurry was then treated with alkali solution (from conduit 7) and treated in container (8) with ozonized oxygen from conduit (9). After separation of impurities in another lamella separator (10), the purified kaolin slurry was acidified with HCl solution (from conduit 12), and dewatered and dried in apparatus (13). The method may be applied to other clay minerals, tale, mica, asbestos and bauxite.
