Patent GB-822675-A (GB)
Title: Improvements relating to methods of and apparatus for separating liquid-gas mixtures
IPC: B04C5/04
Filed: 1957-08-12
Abstract: <PICT:0822675/III/1> Liquids are freed from contained gases by passing the liquid through a curved nozzle 1, Fig. 1, to impinge tangentially on the inner surface of a vertical cylindrical vessel. The nozzle 8 is provided with a diffuser 3, whereby the liquid is subject to pressure and accelerates at 7, and then flows without atomization in a spiral path around the inside wall 2 of the vessel upon which the liquid deposits as a film.  The substantially dry gas flows around the lower edge of an inner concentric wall 4 and rises to an outlet.  The inlet tube 6 may have a smaller radius of curvature than the vessel, to increase centrifugal force on the liquid.

Title: Iridescent composition and method of its preparation
IPC: B29C69/00
Filed: 1971-04-19
Abstract: 1353392 Iridescent polymeric materials ZAIDAN-HOJIN OYO KOGAKU-KENKYUJO 19 April 1971 [31 March 1970] 25723/71 Heading C3P Iridescent polymeric materials comprise a three-dimensional closely-packed regularlyarranged structure of uniform polymeric microspheres having a particle diameter in the range 1000-4500  and derived from a polymeric latex having film-forming properties when dried below 60 C., the structure having been stabilized by surrounding the microspheres with a polymeric material which has no measurable solubilizing effect on them and has a refractive index differing from that of the microspheres in absolute value to the extent of up to 0À1 to provide optical discontinuity. The materials are made by (1) allowing a suitable latex to stand in a quiescent state until iridescence is observed, whereby the particles of the latex become compacted and regularly arranged, (2) reducing the water content to below 20 wt. per cent while maintaining the state of quiescence, (3) removing residual water from the compacted structure by addition of a water-miscible inert organic liquid, e.g. ethylene glycol, glycerol, acetone, methanol, ethanol, isopropanol or butanol, (4) surrounding the compacted structure with suitable monomer(s), and (5) polymerizing the monomers, e.g. in the presence of benzoyl peroxide. In examples, the original latex is selected from styrene/butadiene copolymer, acrylonitrile / butadiene, acrylonitrile / butyl acrylate, vinylidene chloride/vinyl chloride, vinyl chloride/vinyl acetate, vinyl acetate/butyl acrylate, vinyl acetate, styrene/butyl acrylate, n-butyl acrylate, methyl methacrylate/butadiene and methyl methacrylate/ethyl acrylate; and the following monomers and monomer mixtures are polymerized around the compacted structure:- methyl methacrylate / diallyl phthalate, methyl methacrylate, styrene/ diallyl phthalate, diallyl phthalate and styrene. In some examples the monomer mixture includes a plasticizer, e.g. dibutyl phthalate, dioctyl phthalate, dibutyl adipate, nitrocellulose or ethyl hydroxyethyl cellulose, and in Ex. 10, the iridescent material is coated with a gelatine film prior to polymerization of the monomer round it.

In electroslag refining in a water-cooled mould 3, the slag is initially melted in a separate crucible 9 and poured into the mould 3 to bridge the gap between the end of a consumable electrode 1 and a water-cooled bottom plate 4 of the mould 3 and the electrode 1 is energized to start electric current flow through the slag before such time as the resistance of a solidified layer of slag formed on the bottom plate 4 would so limit the current to prevent the establishment of the process. The electrode 1 may be energized before the slag is completely poured. The slag is automatically poured from the crucible 9 when slag powder in a taphole 17 melts and a destructible disc or plug of asbestos, metal or combustible material is destroyed. The slag is melted in the crucible by a non- consumable electrode 15 passing current to the crucible 9 or by two or more electrodes arcing across to each other. The melting of the slag may be initiated by passing current through metal or graphite included in an upper layer of the slag, firing an exothermic mixture, or striking an arc between an electrode and graphite rod and drawing out the arc to melt a pool of slag. The crucible 9 stands on a watercooled metal base 20 electrically connected to the crucible. The mould 3 comprises a watercooling chamber 6 supplying a water curtain 5 that is collected in a trough 7.
