摘要： 1423703 Coating copper wire NITTO ELECTRIC INDUSTRIAL CO Ltd 4 April 1973 [4 April 1972] 16202/73 Heading B2E [Also in Divisions B5 and C3] Cu wire is coated with a solution (S) for making a heat-resistant polymer comprising (1) a solution of a prepolymer (P) and (2) a blocked polyisocyanate or polyisothiocyanate (I) where (P) is made by reacting an organic diisocyanate or diamine with a molar excess of 1, 2, 3, 4-butanetetracarboxylic acid or anhydride thereof; (P) has at least one imide group in its main chain and an acid group at each end of the molecule. (I) may contain an imide or amide group or hydantoin ring in its main chain. Solution (S) may have a non-volatile content of 20-60% wt. and viscosity 500-15,000 cp at 30%. The polymer may be made by heating the solution (S) to which a polymerization accelerator, e.g. an organometallic salt or tertiary amine, may have been added. The final polymer may be obtained by post-hardening after removal of the solvent from the solution after coating on to Cu wire. Specification 1106915 is referred to.

摘要： 1,194,093. Making hollow articles and road vehicle details; stamping; rolling; angular bending. NITTO ELECTRIC INDUSTRIAL CO. Ltd. 17 Jan., 1968, No. 2635/68. Headings B3A, B3E, B3M and B3Q. [Also in Division B2] Metal surfaces are protected during working, e.g. press deep drawing, press bending, and multi-step rolling by the application of an adhesive sheet comprising a flexible plastics material coated with a pressure sensitive adhesive consisting of a cured rubbery polymer of an ester of acrylic acid containing at least 50 mole per cent acrylic acid ester units and having a Mooney viscosity of at least 20 ML 1+4 when measured at 100‹ C. prior to curing (see Division In the Examples (2) a stainless steel plate protected by a sheet comprising a transparent polyvinyl chloride film coated with an acrylic ester-acrylonitrile copolymer adhesive on one side and a low-friction silicone rubber on the other side was deep drawn in a press to form the pouring mouth of a Thermos bottle; (3) stainless steel plate protected by a sheet comprising polyvinylidene chloride film coated on one side with adhesive butyl acrylate-acrylonitrile copolymer and on the other side with acrylonitrilevinyl octadecanoate copolymer was roll-formed into a spandrel; (5) steel plate protected by a polyethylene film coated with adhesive acrylic ester-acrylonitrile-acrylic acid terpolymer on one side and low friction silicone rubber on the other side was press-formed into an automobile bumper.
