Title: Improvements in the manufacture of resin-aggregate pipes
IPC: F16L9/14
Filed: 1967-01-23
Abstract: 1,139,153. Moulding pipes. HUMES Ltd. 23 Jan., 1967 [27 Jan., 1966], No. 3293/67. Heading B5A. [Also in Divisions C3 and F2] In apparatus for making a pipe from a resinaggregate mixture a motor 1 drives discs 2 of a mould 8 and a compacting roller 4 provided with a socket-forming enlargement 5 is supported on hydraulic rams 6 adapted to bring the roller into contact with the mixture 9, the roller being rotatable by a drive 7. The mixture is introduced into the rotating mould and the roller which rotates at a speed greater than that of the mould is forced against the mixture by the rams until the speeds of the roller and the mould are substantially equal and the mixture commences to stick to the roller, the pressure then being reduced to allow the roller to attain the original speed thereof: the speed differential between the mould and roller causes the roller to be cleaned of adhering material. Pressure is then re-applied on the mixture and these steps are repeated as long as some of the mixture adheres to the roller and when this no longer occurs and compaction is completed the pipe is cured or removed from the mould. The resin consists of a polyester, an epoxy, a coal tar epoxy, polyurethane, furane, bitumen, pitch or a monomer-polymerization catalystaggregate mixture, suitable monomers being styrene, and methyl methacrylate and organic peroxides. The aggregate may be crushed basalt or rock of any type or brick or tile, gravel, sand, toscanite, quartz or quartzite and the mixture may include fillers such as silica, talc, barytes, stone or brick or tile dust, carbon black and pigments. The proportion of resin to aggregate is between 1 part of resin to 12 parts and 20 parts of aggregate by weight.

Title: Method of and apparatus for moulding polythene
IPC: B29C33/56
Filed: 1952-02-08
Abstract: Polythene is moulded in a metal mould, at least part of the moulding surface of which has a coating 0.0005 - 0.0015 inch thick of polytetrafluoroethylene, polytrifluorochloroethylene, a thermoset resin which is resistant to the moulding temperature and has a coefficient of thermal conductivity below 6 B.T.U./sq. ft./hour/ DEG F./inch, or a combination of such resins. Polytetrafluoroethylene and polytrifluorochloroethylene may be applied as a fluid dispersion in water or in an organic liquid and then baked on the surface.  The thermoset resins may be applied in a suitable solvent by spraying or dipping and cured on the surface, the heat removing the solvent.  The preferred thickness for the coating is 0.002 - 0.003 inch and the preferred thermal conductivity is 1.0 - 2.5 B.T.U./sq. ft./hour/ DEG F./inch.  The invention is chiefly advantageous for injection moulding, and the mould may be of any usual metal, steel or beryllium copper alloy being mentioned.  If the coating is applied to parts only of the moulding surface to form a pattern, a glossier surface is produced on the article corresponding to that pattern.  To the ethylene polymer moulding powder may be added small amounts of, e.g. heat and light stabilizers, pigments, or anti-static agents, and it should preferably be heated to 275 DEG F.-450 DEG F., the mould temperature being 70 DEG F.-120 DEG F.  Two specific examples are given in which the coating material is an alkyd modified urea - formaldehyde resin.  Moulded article mentioned are bottles, beakers, bottle caps, buttons, plates, electrical parts and toys.

[Class 69 (iii)] [Also in Groups II and XXVIII] A liquid mixture is agitated in a container a, Fig. 1, by withdrawing some of the liquid by a pump and circulating it through a pipe g to an injector at the base of the container. The injector comprises a body b, Fig. 2, having apertures c through which liquid from the container is induced into a chamber d by a vertical jet of liquid from an orifice e. Liquid is delivered under pressure to a disc l, containing the orifice e, through radial ports i in a bush n. The liquid induced into the chamber d, together with the jet from the orifice e, flow through an outlet pipe j of larger diameter than that of the pipe g. A concave baffle disc k is slidably mounted on the pipe g, and distributes the outflow from the pipe j.

Title: Process for the production of metals by reduction of their compounds
IPC: C22B34/12
Filed: 1956-02-09
Abstract: Metals are produced by reduction of their vaporous halides with reduction metals such as alkali metals or magnesium, the reduction metal being supplied to the reduction zone in finely divided, preferably atomized form.  The halide and reducing metal may be separately introduced through two concentrically arranged inlets between which is an annular space for the introduction of an inert gas, the reaction thereby being caused to take place at some distance from the inlets and the produced metal being deposited on a deposition surface within the reduction zone. Alternatively, a central nozzle, for introduction of a vaporous halide may be surrounded by a plurality of nozzles for reduring metal, the latter nozzles being of elongated, and preferably oval cross-section.  The invention is applicable to the reduction of halides of titanium, zirconium and thorium and also in the production of alloys in which case a plurality of halides may be introduced through separate nozzles or in admixture through a single nozzle.
