Patent number: 4367309Abstract: Highly stable glycoprotein derivative compositions showing little tendency to decrease in physiological activity thereof are produced by reacting an aldehyde-group-containing glycoprotein (A) with an SH- or OH-containing material (B), and if necessary further reacting the resulting product with an SH- or OH-containing material of the same or another kind. They are used as diagnostic reagents or hydrolytic catalysts.Type: GrantFiled: January 31, 1979Date of Patent: January 4, 1983Assignee: Sanyo Chemical Industries, Ltd.Inventors: Shigeharu Kondo, Junichiro Kikutake, Masakazu Sugiura, Masaru Yoshida

Patent number: 4365060Abstract: The invention provides a novel enterosoluble capsule for containing a medicament, which is shaped with a hitherto not used novel cellulose derivative. The cellulose derivative is a mixed ester of an alkyl-, hydroxyalkyl- or hydroxyalkyl alkylcellulose esterified with succinyl anhydride and an aliphatic monocarboxylic acid anhydride. The enterosoluble capsules have excellent enterosolubility behavior as well as sufficient pliability even without the addition of a plasticizer which is almost indispensable in the prior art materials. The cellulose derivative can be shaped into capsules not only by the conventional dipping method but also by the plastic deformation at an elevated temperature under pressure such as compression molding, vacuum forming, matchedmold forming and the like.Type: GrantFiled: April 15, 1980Date of Patent: December 21, 1982Assignee: Shin-Etsu Chemical Co. Ltd.Inventors: Yoshiro Onda, Hiroaki Muto, Kazumasa Maruyama
-
Patent number: 4362839Abstract: A modified polyalkylene terephthalate composition comprising polyalkylene terephthalate and polyoxyalkylene compound having metal salt of organic carboxylic acid. The composition, which can be used as a molding material, has improved workability, high crystallizing rate and excellent mechanical strength.Type: GrantFiled: September 5, 1980Date of Patent: December 7, 1982Assignee: Kanegafuchi Kagaku Kogyo Kabushiki KaishaInventors: Satoshi Tonoki, Kazushi Hirobe, Tadashi Osawa, Masahiko Nishigaki
-
Patent number: 4362565Abstract: A solid color former composition is produced in a low-dusting form by admixture with 0.1 to 10% by weight, based on the weight of the color former, of an organic hydrophobic liquid or low melting solid, which does not react with the color former.Type: GrantFiled: October 16, 1980Date of Patent: December 7, 1982Assignee: Ciba-Geigy CorporationInventors: Reginald N. Pineger, Malcolm C. Clark
-
Patent number: 4361681Abstract: This invention relates to a high molecular weight polyethylene terephthalate composition comprised of a plurality of polyester chains wherein a substantial number of said chains have at least one end group corresponding to a formula selected from the group consisting of ##STR1## said composition having a reduced acetaldehyde generation rate.Type: GrantFiled: November 3, 1980Date of Patent: November 30, 1982Assignee: The Goodyear Tire & Rubber CompanyInventor: John C. Bernhardt
-
Patent number: 4359047Abstract: A gelatinous adhesive composition and a tacky article of manufacture are produced by heating at least one polyhydric alcohol and at least one material selected from the group consisting of naturally occurring high molecular weight polysaccharide gums, other than gum Karaya, and resins which are a copolymer of a vinyl ether and a second component selected from maleic anhydride and its corresponding free acid, together in the absence of solvent to promote chemical reaction between the components and to drive off water produced in the reaction, the reaction being carried substantially to completion. In another embodiment, the components are at least one polyhydric alcohol, a resin which is a copolymer of a vinyl ether and a second component selected from maleic anhydride and its corresponding free acid, and a material selected from the group consisting of gelatin and naturally occurring high molecular weight polysaccharide gums.Type: GrantFiled: March 20, 1980Date of Patent: November 16, 1982Assignee: Advance Tapes (U.K.) LimitedInventor: Jan J. Potaczek
-
Patent number: 4357164Abstract: An ink composition for waterless lithography having good printing properties which makes it possible to print from a lithographic printing plate with one fluid without using any kind of water fountain system to mask a non-image area, said ink composition containing high-boiling petroleum solvent mixtures which have a boiling point higher than 200.degree. C. and which contain less than 5% by volume of aromatic components, and in addition to the above containing an aliphatic acid ester, an aliphatic dibasic acid ester and/or a phosphoric acid ester.Type: GrantFiled: December 2, 1980Date of Patent: November 2, 1982Assignee: Sakata Shokai, Ltd.Inventors: Kunio Tsuji, Toshiaki Tsuji, Otugu Hayashi, Tsutomu Hayashi
-
Patent number: 4356819Abstract: An article of manufacture with adhesive properties comprising a gelatinous adhesive composition dispersed in a plastics matrix. The gelatinous adhesive composition is the resulting product of heating together in the absence of solvent at least one polyhydric alcohol and at least one material selected from the group consisting of gelatin, naturally occurring high molecular weight polysaccharide gums, and resins which are a copolymer of a vinyl ether and a second component selected from organic acid anhydrides and their corresponding free acids. Heating promotes a chemical reaction between the components and also drives off water produced in the reaction which is carried substantially to completion.Type: GrantFiled: March 20, 1980Date of Patent: November 2, 1982Assignee: Advance Tapes (U.K) LimitedInventor: Jan J. Potaczek
