Abstract: A combustion inhibiting composition for use in conjunction with a solid, gas-generating charge, the composition comprising an organic polymeric material containing an oxygen-containing organic filler compatible with said polymeric material, the oxygen to carbon atom ratio of the composition being at least 1:3.

Abstract: A priming composition for an explosive device using a double salt of hypophosphite, especially lead nitrato-hypophosphite.

Abstract: A method of producing a priming composition comprising reacting components to produce a primary explosive and a by-product which remains in the composition.

Abstract: A double base propellant charge is primed with a dimethyl siloxane resin before application of a silicone elastomer inhibitor to the primed surface. There may be a barrier coating, preferably of a polyvinyl acetal resin, between the double base material and the primer.

Abstract: A method of supporting a ferromagnetic sheet having a tacky layer on its upper surface comprises locating the sheet on a support which comprises a sheet of glass having on its upper surface a layer of magnetic material.

Abstract: An electrolytic cell, particularly one for use in the production of foil, in which the cathode comprises a rotating drum having a conforming anode spaced therefrom with a melded fibre interlayer. The interlayer remains stationary while the drum rotates over the fibrous surface, thereby breaking up the depleted barrier layer adjacent the cathode, avoiding arcing and reducing the tendency for the cathode deposit to grow in a modular manner.

Abstract: A continuous method of manufacturing a plurality of sheet material blanks each having a surface uniformly coated with a tacky layer comprises passing a long length of the sheet material through a first station in which tapes are applied to a surface of the sheet material transversely to the direction of movement of the sheet material and at longitudinally spaced-apart locations, at a second station applying a continuous layer of tacky material to the surface of the sheet material and over the tapes so that tapes mask portions of the surface, at a third station removing the tapes to leave transverse regions free of tacky material and then cutting the sheet material in the regions which are free of tacky material to thereby produce a plurality of sheet material blanks.

Abstract: A plug for closing an opening in a partition between rocket motor chambers is made in segments and will resist a relatively high pressure differential between the chambers in one direction but will unblock the opening in response to a relatively low pressure differential between the chambers in the other direction.

Abstract: A high strength creep resistant titanium alloy comprising titanium, 6% aluminium, 5% zirconium, 0.5% molybdenum, 0.25% silicon is disclosed in a particular heat-treated condition. The alloy is particularly useful for engine components.

Abstract: Solid propellant charge bonded directly to combustion inhibition material comprising elastomeric or polymeric material containing a compatible particulate filler material constituting at least 50wt.% of the combustion inhibition material.

Abstract: A titanium base alloy for aeronautical use having good high temperature creep properties and being oxidation-resistant, the alloy being 5-6wt% aluminum, 21/2-41/2wt% tin, 2-4wt% zirconium, 0.75-1.25wt% niobium, 0.1-0.6wt% molybdenum, 0.2-0.4wt% silicon, balance titanium, apart from incidental impurities. The alloy may be beta heat treated and aged, optionally with an intermediate heat treatment before the aging.

Abstract: An anode, particularly an anode basket, having on its exterior surface a layer of open, non-woven fibrous mat to protect the anode from accidental contact with a cathode or with an electrically conducting member in contact with the cathode.

Abstract: An energy absorbing body comprising glass spheres embedded in elastomer, preferably with a metal reinforcing skeleton, for example aluminium honeycomb extrusion.

Abstract: Locating a tacky polymer-coated steel sheet on a magnetic rubber-covered glass support by sliding the support out from under a shield and carrying the steel sheet with the magnetic support gradually to place the sheet on the support.

Abstract: A method of burning refuse to obtain heat which comprises injecting refuse through the back wall of a coal-fired moving grate furnace so that the refuse is burnt either in flight or falls onto the moving bed of coal and is burned with the coal.

Abstract: A former for a magnetic coil, particularly a superconducting magnet of the filamentary intermetallic wire type in which the coil is wound green and reacted after winding, the former being typically of stainless steel having an alumina coating flame sprayed onto its surface.

Abstract: A method of electrowinning metals in which the anode comprises a foraminate container containing particulate material chosen from the group electrically conducting non-polarizing compound of a metal and a non-metallic element.

Abstract: A bipolar, lead acid battery incorporating titanium and/or zirconium electrode supports and having a fibre filling to maintain a pressure on the active mass located on the supports.

Abstract: A mechanically strengthened intermetallic superconductor formed around filaments of one component of the superconductor in a matrix material. The selection of specified relative proportions for the components of the assembly leads to enhanced mechanical properties of the superconductor in the composite.

Abstract: A cathode in which the hanger bar is formed of titanium cored copper, the cathode being in the form of a continuous sheet of titanium spotwelded along one edge to the titanium core of the hanger bar. There may be an intermediate block between the titanium core and the continuous sheet.
