Abstract: A portable warning and blinking signal device comprises one or more electroluminescent panels, a support, a luminescent surround to the panels and a battery-operated power supply giving an intermittently-generated A.C. output so that the panels "flash." The device may be mounted to form a flashing barricade, a 360 degree flashing lamp, a rope of spaced flashing elements, or a flashing garment.  The electroluminescent panels comprise a phosphor between a transparent plastic electrode and a flexible metal foil electrode, e.g. aluminium, and may be encapsulated in polyethylene terephthalate. The electrical supply described comprises a 12-volt battery (20, Fig. 7) connected to a transformer (22), transistor (26) and condenser (30) to give a flash rate of 60 cycles per minute, with a duty cycle of 20-30%, each flask being at 500 c.p.s., 200 volts. The luminescent or phosphorescent material may be painted on a support, e.g. transparent polyvinyl chloride 0.04 inch thick, leaving windows for the electroluminescent panels, and the support then fixed to the panels using a contact adhesive, to give a water-tight assembly. Electroluminescent phosphors mentioned are copper-activated zinc-cadmium sulphide, cadmium sulphide, cadmium tungstate, zinc silicate or zinc sulphide, with or without metal activators.  Various coloured plastic overlays may be mounted in front of the electroluminescent panels.  The device may incorporate a photo-switch to activate the electroluminescent panels only at night.

Abstract: 1377084 Antimony pentachloride FARBWERKE HOECHST AG 17 Nov 1971 [6 March 1971] 53472/71 Heading C1A Antimony is recovered as the pentachloride from solutions containing antimony as chloride and/or fluoride, hydrocarbons substituted with chlorine or both chlorine and fluorine and inorganic impurities, by converting any antimony fluorides in the solution to antimony chlorides, distilling off halogenated hydrocarbons to concentrate the solution, establishing the solution at a temperature of at least 60‹ C. to decompose any SbCl 5  in the solution into SbCl 3  and chlorine, separating residual halogenated hydrocarbons and any other organic impurities by extracting with an organic solvent, oxidizing with chlorine the antimony trichloride so obtained to antimony pentachloride and separating the latter from the inorganic impurities. The initial solution may be a spent catalyst solution, obtained in the fluorination of halogenated hydrocarbons using SbCl 5  as catalyst, and generally containing chlorinated or fluorochlorinated hydrocarbons, inorganic and organic impurities, e.g. FeCl 3  and hexachloroethane and antimony chlorides and fluorides (SbF 3  and SbF 5 ). The latter are converted into antimony chlorides by heating the solution suitably at 40‹-130‹ C., the antimony fluorides reacting with chlorinated hydrocarcarbons present and if desired additionally added chlorinated hydrocarbon, e.g. CCl 4 . Halogenated hydrocarbons are distilled off simultaneously or subsequently and the concentrated solution is heated at e.g. 80‹-300‹ C. to decompose SbCl 5  present, the liberated chlorine being used in the rechiorination step. Organic impurities, e.g. fluorinated and chlorinated hydrocarbons, e.g. C 2 Cl 6  are then solvent extracted preferably by contacting with a halogenated hydrocarbon, suitably that obtained in the preceding distillation, at an elevated temperature of up to 100‹ C. and then cooling to not less than 10‹ C. Rechlorination of the SbCl 3  is preferably effected 60‹-150‹ C. at 0-4 atmospheres gauge and the resulting pentachloride separated from inorganic impurities, e.g. FeCl 3  by distillation under reduced pressure.
