Patent GB-899226-A (GB)
Title: Process for the polymerisation of unsaturated organic compounds in aqueous dispersion
IPC: C08F275/00
Filed: 1959-07-16
Abstract: Unsaturated organic monomers are polymerized in an aqueous medium containing a dispersing agent containing or consisting of a polyvinyl phosphoric acid or salt thereof.  The process is especially applicable to the polymerization of vinyl chloride but may also be used for the homo- or copolymerization of other monomers such as vinyl bromide, acetate and butyrate; vinylidene chloride; styrene; pmethyl styrene; acrylic acid esters and butadiene.  The polyvinyl phosphoric acid may be obtained by reacting polyvinyl alcohol with phosphorus oxychloride or pentoxide, orthophosphoric acid, or a mixture of phosphoric acid and urea.  Instead of polyvinyl alcohol they may also be derived from completely or partially hydrolyzed polyvinyl acetate or copolymers of vinyl alcohol with higher vinyl esters or acrylic, methacrylic or maleic acid.  Preferred salts are the alkali metal and ammonium salts especially the ammonium salt containing not more than 19,9% phosphorus and 9,0% nitrogen.  The aqueous medium may also contain an ionic and/or non-ionic wetting agent and/or a neutral-, acid- or basicreacting salt or an organic or inorganic acid, e.g. dodecyl benzene sodium sulphonate; sodium tetradecyl, pentadecyl or octyl sulphate; sodium aryl alkyl polyether sulphonates; saponified red oil (crude sodium oleate); sodium laurate, caprate, caprylate or caproate; potassium stearate; calcium oleate; sorbitan monolaurate; polyethylene glycol ethers of dodecyl phenol; pentacrythritol monooleate; calcium or ferric chloride; oleic acid; and boric acid.  In an example vinyl chloride is polymerized using dilauryl peroxide as catalyst in water containing sodium bicarbonate and monoammonium polyvinyl phosphate.

Title: Improvements in and relating to filters
IPC: B01D29/00
Filed: 1924-10-25
Abstract: 225,524. Soc. Baudrey et Bergeron. Nov. 29, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Filters having sheet filtering-materials.- Means are provided for causing a back flow of filtered liquid through the filtering medium without stopping normal filtration and without allowing the back flow liquid to mix with the filtered liquid. Liquid passes from an inlet 6 to outlet 8 through metal gauze surrounding a perforated surface 2 arranged within a casing 5. Suction nozzles 11 on tubes 12 connected to a tube 13 passing out at the end of the casing, are so arranged that when the tube system is rotated by means of a handle 16 and shaft 15 all parts of the medium are successively cleansed by back flow from the inside of the cylinder into the nozzles. The apparatus may be arranged for outward filtration through the surface 2, the nozzles being placed on the inside. An arrangement in which the nozzles are moved by a turbine and in which an automatically operated valve controls the suction is shown in Fig. 3. Nozzles 28, 30 form part of the suction passage, communication between them being normally closed by a piston valve 29. When, on account of clogging of the filter, the pressure of the unfiltered liquid communicates through an inlet 26 to the base 25 of the valve overcomes a weight 35 and the pressure of a liquid, which may be the filtered liquid, communicated through an inlet 22 to the top of the valve, the valve piston 29 is pushed upward and the suction operates on the filter. At the same time the liquid from the inlet 22 passes through orifices 39 and an outlet 23 to a turbine T from which the suction nozzles receive their rotary motion. From the turbine this liquid passes through nozzles 20, 21, a collar 27, which normally closes communication between these nozzles, being raised so that it is under pressure from this liquid on its lower surface. The valve piston moves back from the position shown to the normal when the filter is cleansed and the pressure of the unfiltered liquid is consequently reduced.
