Abstract: 1,208,345. Graft polymers. AMERICAN CYANAMID CO. 1 Feb., 1968 [23 Feb., 1967], No. 5198/68. Heading C3G. A process comprises interpolymerizing (A) from 75% to 5% by weight of a copolymer of (1) ethylene, and (2) at least one comonomer selected from vinyl acetate, ethyl acrylate, acrylic acid, methacrylic acid, methyl acrylate and stearyl methacrylate, said copolymer containing from 50 to 95% by weight of ethylene, with (B) from 25% to 95% of a monomer component consisting of (1) at least 50% by weight of methyl methacrylate, (2) 0% to 50% of vinyl acetate or ethyl acrylate or mixtures thereof, and (3) 0% to 20% of a copolymer - izable monomer, the interpolymerization being carried out in the presence of a free-radical catalyst at a temperature of 10‹ to 150‹ C. and in the absence of water. In Examples 1 to 11, an ethylene-vinyl acetate copolymer is crosslinked with dicumyl peroxide prior to being dispersed in a toluene/graft monomer mixture and grafted with methyl methacrylate, alone or together with vinyl acetate. Graft polymers are prepared similarly in Examples 13 to 20, except that the ethylene copolymer substrate is not cross-linked and the graft monomers comprise a mixture of methyl methacrylate with ethyl acrylate, or (a) the substrate is a crosslinked ethylene-stearyl methacrylate copolymer and the graft monomers are methyl methacrylate, vinyl acetate and acrylic acid; (b) the substrate is a cross-linked ethylene-methyl acrylate copolymer and the graft monomers are methyl methacrylate, ethyl acrylate and vinyl acetate; (c) the substrate is a cross-linked ethylene-acrylic acid copolymer and the graft monomers are methyl methacrylate, vinyl acetate and acrylonitrile; or (d) the substrate is a cross-linked ethylene-methacrylic acid copolymer and the graft monomers are methyl methacrylate, ethyl acrylate and stearyl methacrylate. In Examples 21 and 22 a solution of ethylene-vinyl acetate copolymer in methyl methacrylate and ethyl acrylate is prepolymerized and then cast into a glass cell and heated to form a cast sheet. A U.V. stabilizer selected from p-methoxybenzylidene dimethyl malonate, 2 - hydroxy - 4 - methoxybenzophenone and 2 - (2<SP>1</SP> - hydroxy - 5<SP>1</SP> -  methylphenyl) benzotriazole and/or an antioxidant selected from butylated and styrenated cresols, 2,5 - di - (t - butyl) - 4 - methylphenol, 2,2<SP>1</SP>- methylenebis - (4 - ethyl - 6 - t - butyl) phenol and tris-(nonylphenyl) phosphite are added to the graft polymers or prepolymers.

Title: A gauge or device for determining any error in the alignment of points or surfaces on three or more fixed objects
IPC: G01B5/00
Filed: 1921-02-15
Abstract: 180,031. Herbert, A. F. Feb. 15, 1921. Gauges.-A device for determining any error in the alignment of points or surfaces on three or more fixed objects consists of a bar a having two aligned flat surfaces b, c at its ends designed to rest upon two of the surfaces to be tested such as f, h and a flat surface d between the ends of the bar inclined to the plane of the two outer surfaces and intersecting it at e. By placing the gauge so that the three flat surfaces make contact with the three points or surfaces to be tested any error of alignment will cause the intermediate surface g to make contact at a point to the right or left of e, and by graduating the face of the bar adjacent to the intermediate surface the error of alignment may be read. In a modification the three flat surfaces are formed on the same side of the bar, so that the gauge mav be applied to the same side of three surfaces. When testing more than three objects, the gauge is moved consecutively.

Title: Improvements relating to ion-exchange processes
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: B01J49/00
Filed: 1956-02-23
Abstract: 835,207. Electric tests. PERMUTIT CO. Ltd. June 21, 1956 [Feb. 23, 1956], No. 5666/56. Divided out of 835,206. Addition to 714,642. Drawings to Specification. Class 37. The Specification describes a number of ion exchange processes which make use of the fact that the change in conductivity of granules of ion exchange material in contact with liquid which has passed through the bed depends both on the exchangeable ions and on the strength of the ion' exchange groups in the material. Thus in a cyclic cation exchange process in which a liquid containing cations exchangeable for hydrogen ions is passed through a bed of granules of strongly acidic cation. exchange material, the conductivity of granules of cation exchange material in contact with liquid which has passed substantially completely through the bed is measured and regenerating action is initiated on a predetermined fall in conductivity. Similarly in a cyclic anion-exchange process in which a liquid containing anions exchangeable for hydroxyl ions is passed through a bed of weakly basic anion-exchange material regenerating action is initiated on a predetermined rise in conductivity of anion exchange material in contact with liquid which has passed substantially completely through the bed. In a further anion exchange process a liquid containing chloride or sulphate ions is passed through a bed of granules or the like of an anion exchange material charged with sulphate or chloride ions and regeneration is initiated upon a predetermined fall in conductivity of anion exchange material in contact with the material leaving the bed if the exchange is of chloride ions for sulphate ions and a predetermined rise if the exchange is of sulphate for chloride ions.

[Also in Groups II and XII] A method of cleaning gas-swept heating surfaces of steam boilers and like heating plant comprises allowing cleaning elements (e.g. steel shot) to fall freely through the plant on to the heating surfaces, cooling the elements rapidly to break up the deposits thereon and separating the deposits from the cleaning elements prior to their return to the system. In an apparatus for carrying out the above method, Fig. 1, the cleaning elements are hurled from distributing members 9, rotated by electric motor 10, and allowed to fall freely within each steam plant 1 thus cleaning the heating surfaces. The elements are then collected in pockets 11, having grids for the separation of lumps of solid matter, and passed to a return conduit 12 where cold air from a fan 13 breaks up the deposits on the elements and returns the elements and the deposit to the cyclone 6. Another fan 14, fed with.flue gases or preheated air, warms the elements to a temperature above the dew point of the flue gases. In the cyclone the cleaning elements are separated from deposits and returned to the distributing members 9 via the hoppers 8: In another form, Fig. 3, the fan 13 is replaced by an injector 12 and the deposits removed from the cyclone by a suction fan (not shown). Loose solid matter may be removed together with the flue gases by throttling the flue gas outlet by a screen 20. Specification 698,103, [Group II], is referred to.
