Title: Improvements in or relating to adhesive compositions and process of producing the same
IPC: C09J121/00
Filed: 1945-01-29
Abstract: A pressure-sensitive adhesive consists of a dispersion in water of a homogeneous blend of rubber and a substantially non-acidic, water-insoluble tack-producing resin having a higher compatibility with rubber than coumarone-indene resins.  Tack-producing resins mentioned are ester gum and "Nevillite" a hydrogenated polymer of unsaturated nonnitrogenous material from coal tar, described in U.S.A. Specification 2,152,533.  Preferably the resin and rubber, and filler (if desired) are mixed together with a small proportion of higher aliphatic or cyclo-aliphatic acid, e.g. oleic, linoleic, abietic, stearic or naphthenic acid.  Water is then mixed in, and then caustic alkali, preferably potassium hydroxide, to form with the acid a dispersing soap at the point of inversion.  The final dispersion is alkaline.  It may be diluted with water to the desired viscosity.  Fillers mentioned are clay, slate flour, carbon black, or zinc sulphide.  In the examples (1) reclaimed rubber, low acid type ester gum, and oleic acid were mixed, e.g. in a Werner-Pfleidener mixer at 190-210 DEG  F.  Water is added and mixing continued. Potassium hydroxide is then added at about 145 DEG  F. and a dispersion of rubber-resin mixture in aqueous potassium oleate is formed.  In example (2) a proportion of Dixie clay is included in the mixture.  Reference has been directed by the Comptroller to Specification 558,815.ALSO:A pressure-sensitive adhesive consists of a dispersion in water of a homogeneous blend of rubber and a substantially non-acidic, water-insoluble, tack-producing resin having a higher compatibility with rubber than coumarone-indene resins.

Title: Improvements relating to the protection of ferrous metal against corrosion
IPC: C23C22/23
Filed: 1945-01-31
Abstract: In a process of making ferrous metal surfaces resistant to corrosion the surface is treated with an aqueous solution of a molecularly dehydrated phosphate radical and a metal of the group consisting of calcium, strontium, barium, zinc and cadmium.  A metal strip may be heated for one minute with a solution containing a soluble calcium salt and sodium metaphosphate whereby a coating of calcium metaphosphate is deposited on the strip, the pH value of the solution being maintained at 5 and the temperature at 65 DEG C.  The ratio of the molecularly dehydrated phosphate radical to the metal radical should be held between .05:1 and 8:1.  Metaphosphates or pyrophosphates may be used but it is stated that orthophosphates do not produce the coating.  The coating does not remain for any length of time but it will protect the surface between the completion of one operation e.g. rolling, and the start of a subsequent operation e.g. lithographing or enamelling.
