Abstract: 1,151,737. Controlling aircraft. ROSEMOUNT ENG. CO. 22 June, 1966 [25 June, 1965], No. 28007/66. Heading B7G. [Also in Divisions F2, G3 and H3] The invention relates to the use of redundancy in a multichannel system to counteract the failure of transmission in any one channel, and the Specification discloses its use in the amplification of two or more electrical signals (see Division H3). In a corresponding mechanical arrangement, which may be used in the control of aircraft, sliding movements are transmitted by rod 181 from point 184 to point 186 and by parallel rod 183 from point 185 to point 187. Links 199, 205 are pivoted to either ends of the rods 181, 183 and their mid-points are pivotally connected by a further rod 182. Breakage of rod 182 does not affect the transmission of movements by the other two rods, and on breakage instead of either of the rods 181, 183 the movement normally transmitted by that rod is now transmitted by the further rod 182.

Patent GB-955533-A (GB)
Title: Process for the preparation of a sugar product
IPC: C13B50/00
Filed: 1962-07-20
Abstract: A sugar-containing, free-flowing, granular product suitable for feeding domestic animals and poultry is made by adjusting to pH 8 a sugar-containing liquid such as clarified or unclarified raw cane juice or a sugar liquor from which some sugar has already been crystallized out, evaporating until the water content is 5-15% while maintaining the concentrate at 90-135 DEG C. in saturated or supersaturated condition, and then incororating a dry, particulate material.  The pH adjustment is by adding milk of lime or the calcium carbonate filter cake obtained the carbon dioxide purification usual in sugar production.  Evaporation may be in a multiple effect evaporator, followed by evaporation in a vacuum pan.  The concentrate may be sprayed on the dry, particulate material, mixing being effected by rotating stirrers.  The process may be initiated with starch or tricalcium phosphate as the particulate material; thereafter the particulate material is a "back-mix" of already prepared product dried to 1.5-3% moisture content.  By adding starch or tricalcium phosphate to the product, the free-flowing property is maintained on storage in a humid atmosphere.  Sodium chloride may be added to the product to discourage use for, or purification for, human consumption.  The product is suitable as a vehicle for feeding urea to ruminants.

Abstract: 468,324. Forging barbed nails. WIT, W. J. DE. Oct. 19, 1936, No. 28413. Convention date, Oct. 19, 1935. [Class 83 (iv)] The barbed wire nail shown in Fig. 6, is made by forging first upsetting the head 4 by a tool 5, Fig. 1, and then barbing and pointing by dies 11, 12. The dies 11 are shaped as shown in Fig. 2, for cutting off the point, and the dies 12 are stepped to form the barbs. These latter dies may be shaped to provide inclined barbs. The dies 12 are adjusted by screws so that they grip the wire during the latter part of the stroke of the dies 11. In consequence of the pressure exerted on the point during the severing operation the nail is moved longitudinally to press the nail shank against the dies forming the barbs. As shown in Fig. 6, the barbs 2 are forged to a position beyond the circumference of the blank.

Abstract: 980,221. Identifying cable cores. WEDNESBURY TUBE CO. Ltd. Aug. 1, 1962 [Aug. 5, 1961], No. 28521/61. Drawings to Specification. Heading H1A. In an electrical cable of the type comprising at least two conductor cores extending through a tubular metal sheath and separated from each other by powdered insulating material, the cores are identified by providing at least one of the cores with a recessed surface. This recess may be a continuous V formed by a beak in the die forming the conductor or it may be a series of discontinuous indentations formed by passing the conductor to be marked between a pair of wheels at least one of which carries projections on its surface. Where more than one core is to be marked, differently shaped recesses may be provided in different conductors, e.g. one set may be rectangular as viewed from the side of the core and another circular. The cable is filled with powdered magnesium oxide which passes down spaces between a compacting ram and the sheath. This compacting fills the recess with the powder, so assisting in the identification. The indentations may be filled with a different insulating material which can be retained in the V to maintain the shape of the core for sealing through a bush. Alternatively, they may be filled with a further metal, e.g. a tin-lead alloy or aluminium, so as not to reduce the core cross-section.

Title: Improvements in or relating to production of uranium metal
Inventor: BUDDERY JOHN HAROLD
IPC: C22B60/02
Filed: 1952-11-13
Abstract: In a modification of the process of Specification 792,952 uranium is produced by heating to 1200 DEG C. in an inert atmosphere a mixture of uranium dioxide, magnesium metal in amount 15 per cent above the stoichiometric, and a minor proportion (about 10 per cent) of dry alkaline earth metal chloride, holding at 1200 DEG C. for at least an hour to promote growth of uranium particles, leaching the product with dilute acid, washing the uranium particles with water and finally vacuum-freeze drying.  Anhydrous, dry, magnesium chloride is the preferred chloride; the mixture is preferably briquetted and dilute acetic (40 per cent) acid used for leaching; whilst addition of a minute quantity of acetic acid and a surface active agent such as "Teepol' (Registered Trade Mark) to the washing water promotes rapid settling of fine particles and reduces washing time.  The uranium particles (moist) may be wax coated by e.g. tumbling with 1.5 per cent of its weight of shredded paraffin wax before the vacuum-freeze drying; then warmed under vacuum to melt and distribute the wax and formed into tubes or bars by cold compacting followed by hot compaction or extrusion.
