Title: Improvements in electrical conductors
IPC: H01B9/00
Filed: 1962-03-07
Abstract: 940,904. Electric cables. ANACONDA WIRE & CABLE CO. March 7, 1962 [July 31, 1961], No. 8785/62. Heading H1A. An electrical conductor consists of a core deformed to compact the individual strands and surrounded by helically wound keystoneshaped wires 16. Originally the wires forming the core 12 were circular in cross-section but are crushed out of shape during manufacture so that the interstices are filled with metal, and their smooth outer surface is surrounded by keystone-shaped wires which may be insulated from each other, e.g. by polyvinyl acetal oleoresin epoxy or nylon. The coating around the keystone members may be made semiconducting particles to allow contact with the stranded shield. Alternatively, the top faces of the keystones may remain bare. The keystones may also be coated on the inwardly facing surfaces and between conductors with a tape of polyester film. The cable may be made by a continuous process in which the keystoneshaped conductors are laid immediately after the compacting but the compacted cable may be wound in a reel and the keystone conductors applied in a separate process.

Title: Dual-layer magnetic recording tape
IPC: C09D5/23
Filed: 1972-02-25
Abstract: 1366192 Magnetic recording tape MINNESOTA MINING & MFG CO 25 Feb 1972 [26 Feb 1971 23 Aug 1971] 8887/72 Heading B2E A magnetic recording tape has a non- magnetisable backing member carrying a duallayer magnetisable coating of up to 600 microinches in thickness, each layer being a homogeneous admixture comprising a major proportion of magnetisable particles and a minor proportion of nonmagnetisable binder, characterised in that the outer magnetisable layer has a thickness of 20-70 microinches and a surface roughness not exceeding about 10 microinches and the inner magnetisable layer has a thickness at least equal to that of the outer layer. In making such tapes the inner layer may comprise a binder and a crosslinking agent such that sufficient curing occurs to prevent any volatile solvent in which the outer layer is applied from affecting the physical properties of the inner layer. Preferably the inner layer contains γ-Fe 2 O 3  and the outer layer CoO modified γ-Fe 2 O 3 . In examples polyurethane elastomer and phenoxy resin in a volatile solvent are used as a medium in which to suspend γ-Fe 2 O 3  before application to a polyethylene terephthalate backing tape. The outer layer is similarly constituted, substituting CoO-Fe 2 O 3  for γ-Fe 2 O 3  alone.

Title: Process for the preparation of alumina
IPC: C01F7/062
Filed: 1929-03-19
Abstract: 330,661. M³ller, W. J., and Hiller, H. March 19, 1929. Alumina; aluminates.-Bauxite is treated with aluminate lye of 20-22 BaumÚ at temperatures above 190 C., and at a pressure corresponding to the vapour pressure at this temperature. The mixture of alumina lye and bauxite may be kept in a continuously progressive movement through the decomposition autoclave by means of a high pressure pump, and allowed to issue from the reaction chamber through a loaded valve or through a corresponding counter-pressure pump. The red slime is separated from the reaction mixture, and the aluminium hydrate caused to separate in a manner known per se. In examples, using a bauxite from Salzburg, 96 per cent of the alumina present goes into solution when treated at 200 with a lye of 20 BaumÚ; using a Hungarian bauxite, 62 per cent goes into solution when treated with a 22 BaumÚ lye at 230 and an excess pressure of 25 atmospheres, and 93 per cent when treated at a temperature of 280-290 and at about 100 atmospheres pressure. In this process, no concentration of the aluminate lye is required at any period (except the concentration by evaporation of the wash liquors to 22 BaumÚ).

Title: Process for the manufacture of benzene hexachloride
IPC: C07C23/12
Filed: 1947-04-09
Abstract: The process of the parent Specification, whereby benzene hexachloride is made by subjecting commercial benzene to a preliminary additive chlorination until the appearance of crystals of benzene hydrochloride, whereupon the unchlorinated benzene is separated by distillation and subjected to additive chlorination until benzene hexachloride is obtained, is modified by carrying out the chlorination step in the absence of air or oxygen.  An undesirable colour and odour in the product is thereby avoided.  Oxygen is removed from the initially purified benzene by distilling the benzene in a current of inert gas, e.g., nitrogen or carbon dioxide, or by blowing an inert gas through it.  An anti-oxidant such as hydroquinone may be added to the benzene, and an inert gas may be mixed with the chlorine used.  In an example, carbon dioxide is freed from oxygen by passing it, admixed with hydrogen, over reduced copper at red heat, and is then bubbled through benzene which has been purified by the process of the parent Specification.  Dry chlorine, freed from air, is then mixed with the inert gases and passed into the benzene.  The product is recovered by blowing with steam.
