Granted: 1993-10-30
Abstract: Abstract of US 5854191 (A) The present invention relates to water-soluble, acid-groups-containing graft copolymers which are at least partially biodegradable and are based on sugars and monoethylenically unsaturated carboxylic acids, sulfonic acids and/or phosphonic acids or the salts of said acids as well as optional further monomers. The present invention further relates to a process for producing the graft copolymers at temperatures of up to 200 DEG C. by means of-radical polymerization initiators, in that a total mixture of 5-60%-wt. mono-, di- and oligosaccharides, the derivatives thereof or the mixtures thereof, and 95-40%-wt. of a monomer mixture comprising at least one monoethylenically unsaturated carboxylic acid, at least one monoethylenically unsaturated sulfonic acid, one monoethylenically unsaturated sulfuric acid ester and/or vinylphosphonic acid or the salts of said acids with monovalent cations, as well as optional further monomers is polymerized. The present invention further relates to the use of the graft copolymers in aqueous systems, for binding multivalent metal ions, inhibiting the water hardness, as additive in detergents and cleaning agents, as textile auxiliary, dispersing agent, in particular for pigments, and as auxiliary agent in the production of paper and leather.

Title: Integrated system for forming sheets and films of synthetic resins
Inventor: CHONG A
IPC: B29D7/00
Filed: 1978-04-22
Granted: 1981-11-17
Abstract: Tubular plastic film is made by extrusion blowing molten polymer derived directly from a polymerization vessel via hot conduit and pumping system.  To prevent build-up of flammable material, such as residual monomer, within the bubble, the bubble is vented via the extrusion die and swept by a supply of non-explosive gas, e.g. air, via an alternative passage through the die.  Reactor is used for manufg. of film from olefin polymers or copolymers, e.g. polyethylene or EVA containing 5-20% vinyl acetate.  Process avoids the use of equipment space and energy associated with conventional prepn.

Abstract: PCT No. PCT/FI87/00042 Sec. 371 Date Sep. 16, 1987 Sec. 102(e) Date Sep. 16, 1987 PCT Filed Mar. 24, 1987 PCT Pub. No. WO87/05844 PCT Pub. Date Oct. 8, 1987.The invention relates to an apparatus to be used when welding pipes together. The apparatus comprises a bellows structure (4, 5) for shielding the weld joint area by internal contact with the pipe ends on both sides of the weld joint (3). When the apparatus is inserted and, especially, pulled out after welding, the bellows tend to be damaged by the hot weld joint. It is the object of the invention to solve this problem. The object is achieved by providing both bellows (4, 5) with radial side supports (14, 15) dragging against the inner surface of the pipes and by arranging the bellows to contract within the radial side supports in the absence of an inner overpressure. Between the bellows (4, 5), centering discs (9, 10) are arranged on hoses (6, 7, 8) for leading a protective gas and compressed air. The hoses (6, 7, 8) are connected with the holders of the bellows by means of a through cotter pin provided with a spring (17) for keeping the pin stationary.

Title: Gas feeding device and deposition film forming apparatus employing the same
Inventor: MIKOSHIBA NOBUNO
IPC: C23C16/448
Filed: 1990-09-26
Granted: 1994-06-15
Abstract: Provided is a gas-feeding device for feeding a starting gas for deposition-film-formation by the chemical vapor deposition method, comprising a container having a space for discharging the starting gas containing an organometallic compound by introduction of a carrier gas; a gas-introducing means connected to the container and having a plurality of gas-introducing openings for introducing the the carrier gas or the starting gas into the container to generate the starting gas; and a gas generation-accelerating means for accelerating the generation of the starting gas.
