Title: Colorless polymers of ª‡-haloacrylic acid derivatives
IPC: C08F20/62
Filed: 1946-05-23
Abstract: Colourless polymers are obtained by polymerizing compositions comprising an a -haloacrylic acid or derivative thereof and a free hydroxyl-containing polymerizable ester of a polyhydric alcohol in an amount of from 0.1 per cent to the limit of its solubility in the acrylic acid compound.  The ester differs from the acrylic compound and is interpolymerizable therewith.  The preferred a -haloacrylic acid derivative is methyl a -chloracrylate, but other suitable compounds are ethyl, propyl, butylphenyl, benzyl, cyclohexyl, allyl and methallyl esters of a -chlor- and a -brom-acrylic acids, and a -chloracrylamide, N-methyl a -chloracrylamide and a -chloracrylonitrile and the corresponding a -bromo compounds. Specified polymerizable esters include ethylene, propylene, butylene and trimethylene glycol, and glyceryl monoesters of acrylic, methacrylic and a -chloracrylic acids, diethylene glycol maleate and fumarate, and diethylene glycol monoesters of angelic and tiglic acids; polyesters of polyhydric alcohols may also be used, e.g. glycerol diacrylate, dimethacrylate and dichloracrylate.  the polymerization may be carried out by mass, solution or emulsion methods, if desired with use of light or oxygen-containing polymerization catalysts.  Specifications 518,970, 636,319, and U.S.A.  Specifications 2,247,790, 2,314,443, and 2,345,126, are referred to.

Filed: 1922-06-06
Abstract: 202,097. Foster, W. H., and Foster, L. June 6, 1922. Piston-valves; outlets.-A manually-actuated tubular piston valve, designed to enable a supply to be diverted to either of two outlets or to enable two separate supplies to be delivered separately or mixed through a single outlet or either of two outlets, is actuated by a toothed pinion engaging a rack formed on one edge of a longitudinal slot in the valve member. In the form shown in Fig. 2, the valve member d has two diametricallyopposed ports d<1> adapted, when the valve member is lowered, by the pinion f engaging the rack d<2>, to divert the separately-controlled supplies arriving through ports b<2>, through an upper outlet e. In the position shown, the mixture is delivered through the spout c<1>. In the form shown in Fig. 4, a single supply connection is provided, and the valve member has a partition, so that the supply may be directed to the nozzle k or to the fountain jet j. In addition to the diametricallyopposed ports, the valve member may have additional ports whereby one or other of the fluids may be delivered separately. The valve member and outlet may be fitted with deflectors or with a check valve to prevent one fluid causing a reversal of flow in the other fluid conduit. According to the Provisional Specification, the valve may be actuated by a screwed spindle push button or lever.

Abstract: 1504598 Marking bottle caps CEBAL 16 April 1975 [16 April 1974] 15722/75 Heading B6J A blocking machine for marking crimped bottle caps 4 comprises an engraved head 37 which under heat causes, after several checks a pigment image to transfer to the caps 4 from a ribbon 38. The presence of a cap 4 is checked by magnetic detector 32 and the depth of crimping is checked using a horizontal roller device the rollers of which enter the crimping area causing the actuation of a microswitch if the diameter of the area is too great. A lever arm 42 and microswitch 47 detect the absence and/or lack of tension in the ribbon 38 and pressure and temperature checks of the head 37 are made respectively using a manometer and thermostat. A relay is closed if all the checks are positive and a jack 67 then moves the head 37 downwards which causes actuation of counting devices. A sprung and toothed rack advances the ribbon 38 which rack may be manually operated. Visual or audible warning devices may be employed.

Abstract: 240,534. Marconi's Wireless Telegraph Co., Ltd., and Brown, J. July 1, 1924. Addition to 199,471. Directive multiplex signalling; coupling aerial detector currents.-The double set of radiogoniometers utilized in the arrangement illustrated in Fig. 3 of the parent Specification, for receiving simultaneous signals from two different directions, is replaced by a single set of divided field coils X, Y, Fig. 1, of which the coils FA are connected across the receiving loops A, whilst the coils FD are across two windings D constituting artificial aerials having the same characteristics as the loops A. The centre coil of one active field coil is earthed at K, as shown, in order to maintain the static balance of the aerial system. Different methods of winding the field coils are described. When the winding is such that the mutual inductance between the loopaerial and artificial-aerial windings neutralizes their effective coupling to the search coils SC1 or SC2, this may be overcome by the introduction of a separate mutual inductance BM, Fig. 3, the value of which can be varied so that the same radiogoniometer can be utilized over a wide range of wave-lengths and with aerials of different sizes.

Abstract: 1,199,042. Phosphoric acid. ISRAEL MINING INDUSTRIES, INSTITUTE FOR RESEARCH & DEVELOPMENT. 1 Aug., 1967 [2 Aug., 1966], No. 16289/69. Heading C1A. Phosphoric acid, obtained by the sulphuric acid acidification of phosphate rock, is purified by extracting with a solvent as defined in Claim 1 of 1,112,033 at a temperature low enough for the formation of a homogeneous extract phase distinct from a residual aqueous phase, separating the phosphoric-acid-containing extract from the residual phosphoric acid, adding water to the extract phase in an amount of from 3-20% by weight to obtain stratification, and separating the lower phase, which is an aqueous solution containing at least 35% by weight purified phosphoric acid. A controlled amount of heat is preferably supplied to keep the temperature of the extract constant while water is being added. The water may be added in one stage, or in two or more stages, the first of which may be a small amount of water to produce a fraction comprising most of the impurities in the extract, which fraction is removed, and, in a further stage or stages, the remainder of the required amount of water is added. The first stage may also consist of a' counter-current wash with water or an aqueous phosphoric acid solution. 0À1-5À0% (by wt.) of sulphuric acid may be added to the original impure acid before contact with the solvent. The residue left after the initial extraction may be acidified by the addition of 30-100% by weight of sulphuric acid, and this solution submitted to the process.
