Title: Improvements in and relating to coils for electrical apparatus
Inventor: STICKLEY WILLIAM ALBERT
IPC: H01F27/28
Filed: 1956-01-18
Abstract: 815,106. Transformers and inductors; electromagnets. THORN ELECTRICAL INDUSTRIES Ltd. Dec. 18, 1956 [Jan. 18, 1956], No. 1759/56. Classes 35 and 38 (2). [Also in Group XXII] A coil for electric apparatus such as a choke, transformer, or electromagnet comprises a flat strip conductor wound into a substantially flat spiral, the turns being insulated from each other and slightly displaced so that their edges 11-18 are in staggered or stepped relationship. In making a choke for fluorescent lighting, a flat strip of aluminium is anodized in a borax and boric acid solution, and wound on an insulating former mounted on a mandrel which is reciprocated by cam action at half the winding rate of the strip. Four such coils are mounted on the limbs of a hollow rectangle of laminated iron. The insulation may be a strip of material wound with the coil. The coil may be coated or impregnated with varnish.
Patent GB-346788-A (GB)
Title: Improvements in magnetic material and in the method of making same
IPC: C21D8/12
Filed: 1930-01-17
Abstract: The manufacture of a magnetic material of high initial permeability and low retentivity comprising one or more ferromagnetic elements includes the step of adding carbon in the melt and a subsequent annealing in the presence of a reducing agent to reduce the carbon present in excess of that required to combine with the oxygen in the material.  By way of example an alloy containing 45 per cent of nickel, 25 per cent of cobalt and 30 per cent of iron may be melted with 0,1-0,5 per cent of carbon in the free state and the product cast, rolled and passed through a wire-drawing machine.  Between passes it is annealed in hydrogen at 900-1250 DEG  C.  A wire or tape for a continuously-electric signalling conductor may thus be manufactured.

Filed: 1951-01-24
Abstract: 697.990. Spinning yarns. T.M.M. (RESEARCH), Ltd., WATSON, W. H., and GILLESPY. R. A. Jan. 7, 1952 [Jan. 24, 1951]. No. 1826/51. Drawings to Specification. Class 120(iii) In a process for producing a yarn from card sliver by subjecting the sliver to a multi-stage drawing process at each stage of which a number of slivers is combined and drawn out as a single sliver, the degree of draft introduced at the first stage exceeds by a substantial amount that which is necessary to produce a sliver of the same weight per unit length as each input sliver. and at each subsequent drawing stage the draft is progressively increased, the output at the final stage being packaged without real twist and spun into yarn in a single final spinning operation. As described, at each stage the packaged length of input or output sliver may be determined by a measured length coiling or winding means, and slivers feeding one delivery for anystage after the first are coiled in a common can at the preceeding stage; the coiling apparatus described in Specification 684,784 may be used. At the final stage the sliver is consolidated as by means of rubbing or condensing leathers, false twist tubes, or calender rollers, and cross-wound into ball or cheese packages for creeling in a spinning frame.

Title: Process for the manufacture of dihydroresorcinol
IPC: C07C45/00
Filed: 1934-01-19
Abstract: Dihydroresorcinol is obtained by subjecting solutions of resorcinol to catalytic hydrogenation in presence of at least one gram-equivalent weight of a strongly-basic compound per gram-molecular weight of resorcinol.  Inorganic or organic bases or salts of strongly alkaline reaction may be used, but it is not necessary to use resorcinol also as a salt.  The reaction may be carried out in aqueous or organic solvents at normal or higher pressure.  According to examples, resorcinol is hydrogenated in with a nickel catalyst in presence of aqueous sodium hydroxide, methyl alcoholic sodium hydroxide, aqueous calcium oxide, alcoholic diethylamine, and with a palladium chloride catalyst in presence of aqueous sodium hydroxide followed by acidifying and extracting with ether.  German Specification 77317 is referred to.ALSO:Dihydroresorcinol is obtained by subjecting solutions of resorcinol to catalytic hydrogenation in presence of at least one gram-equivalent weight of a strongly basic compound per grammolecular weight of resorcinol.
