Title: Improvements relating to fusible electrodes for use in electric arc welding
IPC: B23K35/40
Filed: 1927-09-15
Abstract: 299,575. Quasi-Arc Co., Ltd., and Strohmenger, A. P. Sept. 15, 1927. Uniting by fusion.-The core of a metallic arc welding electrode is covered with a wrapping of a matted fibrous mineral silicate such as blue asbestos, amosite, or a mixture of both, which is then cut through helically and the grooves so made filled with a cementing material. Asbestos composed of short fibres which cannot be spun may thus be used while still retaining the helical formation of the covering. The core a may be delivered by feed rolls through a rotating headstock l so as to rotate the core during feeding, and may first pass through a bath e containing sodium silicate solution so as subsequently to bind the strips of matte asbestos which are wound round the core from stationary spools m. The strips are made by pressing or felting together the fibres with or without a small quantity of sodium silicate solution. The covered core may then be passed through a device for drying and compressing the covering on the core, whereupon one or more helical grooves are cut by stationary cutters or by disc cutters o. The disc cutters may be mounted on a head n rotated at a different speed from the core so as to produce a helix of any desired pitch. The covered core is then passed through a bath h containing a material of higher melting point than the covering, such as lime or chalk, which fills the grooves and forms a cement with the sodium silicate, excess being removed by passing through a die k. The core may be covered by feeding it without rotation through a rotating head carrying the spools of asbestos strip. Loading materials for use in formation of the flux or for varying the properties of the weld, such as silicate of iron, ferro-silicon, ferro manganese, vanadium, titanium may be supplied to the asbestos during formation of the strip or may be supplied during winding thereof on the core. Several overlapping layers of strip are wound on the core, according to the thickness of the covering desired, the amount of overlap being varied by varying the angle of winding. Specifications 1274/12, 11079/12, 13538/14 and 160,957 are referred to.

Title: Improved process for making foamable thermoplastic polymers
IPC: C08J9/18
Filed: 1962-06-26
Abstract: A process for the production of foamable, spherical or substantially spherical polymer particles, such as beads, by incorporation of an expanding or blowing agent into a particulate thermoplastic polymer by impregnation at an elevated temperature and at elevated pressure, while agitating in the presence of water and of a dispersing agent, is characterized in that the particulate thermoplastic polymer is employed in the form of elongated segments or sections of the polymer.  Best results are achieved if the segments or sections have in at least one direction, preferably in the direction of the longer axis, a molecular orientation or strain greater than in the other direction or directions. Such segments are obtained by extruding the polymer, for example as cylindrical or polygonal segments or as strands, ribbons or tubes. Strain is also produced by cold-drawing or drawing to elevated temperatures.  The segments preferably have a length-to-width ratio between 12:1 and 2:1. Suitable dispersing agents are soaps and wetting or emulsifying agents, especially those described in Specification 988,289. Thermoplastic polymers specified are homo- and copolymers of vinyl aromatic compounds or copolymers with vinyl esters, esters of acrylonitrile, acrylic or methacrylic acid or with natural or synthetic rubbers, and also blends of a styrene polymer and a minor proportion of natural or synthetic rubber. Saturated aliphatic hydrocarbons, perchlorofluorocarbons, and tetra-alkyl silanes are suitable blowing agents.  The process can be applied to polymer already containing part of the blowing agent.  The mixture used in the impregnation may also contain water miscible compounds, e.g. alcohols and glycol monoethers, organic, bromine - containing flameproofing agent, and an organic peroxide having a half-life in benzene at 100 DEG C. of at least 2 hours.  In examples (1) a suspension of polystyrene rods (0.55 mm. dia. by 2.55 mm. long) in aqueous medium containing carboxymethyl cellulose, ammonium salt of sulphonated polyvinyl toluene and ammonium sulphate is treated under pressure at 135 DEG  C. with successive portions of pentane while stirring the mixture; (4) segments of extruded rods of a styrene/acrylonitrile copolymer are impregnated successively with dichlorotetrafluoroethane and n-pentane, in a similar process; (5) saturated hydrocarbons of b. pt. 30 DEG  to 60 DEG  C. are used in a process similar to (1).  The particles are foamed by heating to 100 DEG  C.

Abstract: 336,710. Robinson, E. Y., and Associated Electrical Industries, Ltd. Aug. 14, 1929. Addition to 320,866, [Class 39 (i), Electric lamps, Arc &c.]. Extrusion machines; rolling - machines. - In applying insulating coatings to the heater wire of indirectly - heated ther - mionic cathodes by extrusion as in the parent Specification, the wire is first drawn through a plastic sludge &c. of the insulating substance and a vehicle or agglutinant and is then passed through a die to form and limit the coating before it is dried or baked. The two operations may be carried out in a single process, the wire from a drum 3 being drawn through a vessel 12 containing porcelain sludge 13 and out through an extrusion aperture 14, a weight 17 and plunger 15 applying pressure to the sludge. The coated wire passes through an oven 20 and blow-pipe. flame 21, the aperture 14 being shielded from heat by a baffle 22 and air-jets 23. The wire may be given two coatings in this manner in succession and may be heated by a blow-pipe flame before passing into the first vessel 12, and the first coating may be heated to biscuit state and the final coating sintered. Alternatively, two initial coatings, preparatory to the coating in the vessel 12, may be given by passing the wire successively over two wheels each driven in the opposite direction to the wire and having a V or U groove dipping into the sludge, the wire being passed through three blow-pipe flames separated by the wheels. In a modification of the vessel 12, the wire passes into the vessel through a narrow tube and the vessel is provided with a compressed-air supply and a variable air-leak, a paper washer on top of the sludge preventing it from drying. In a modified process, the wire is coated by drawing over a driven wheel dipping into the sludge and the coating is at once moulded by passing the wire through a die or through co-operating semi-circular grooves on two driven rollers. These two rollers may be lubricated with oil to prevent the sludge from sticking. The coated wire may be cut into lengths.
