Title: Improvements in or relating to the ornamentations of surfaces of articles or materials
IPC: B44F5/00
Filed: 1930-07-10
Abstract: Irregular patterns, resembling the marking on certain leathers, such as crocodile leather, are produced on materials such as indiarubber, glass, wood, leather, metal, or artificial resins, by applying thereto emulsions or dispersions of organic materials, which are adapted to produce coagula of initially low mechanical strength, which do not form a continuous film, but tend to gather into irregular ridges.  Such coagula, which are preferably formed comparatively slowly, are produced by adjusting factors such as alkalinity or concentration of the dispersions, or strength of the coagulating-medium.  The film may be left on the backing, or removed and applied to another surface.  Natural or artificial dispersions of indiarubber or other natural resins in non-vulcanized or vulcanized condition, gelatine, casein, viscose, synthetic resins, or cellulose esters and ethers may be employed. Aqueous emulsions or dispersions of solutions in organic solvents, or organic emulsions of aqueous solutions may be used.  The coagulation may be effected merely by drying, with or without heating, or by means of a coagulating-solution, or a dehydrating and setting solution, as described in Specification 303,544, [Class 70, Indiarubber &c.]. Single or mixed liquids which effect coagulation and swelling concurrently, as described in Specification 324,988, [Class 70, Indiarubber &c.], may also be used.

Title: Improvements in or relating to containers for asphalt and analogous bituminous substances which tend to adhere to the surfaces of metals
IPC: B65D25/14
Filed: 1931-07-23
Abstract: The interior surfaces of metal barrels, drums, &c. for asphalt or other solid, semisolid or plastic bituminous substance such as bitumen, tar, or pitch, which tend to adhere to the surfaces of metals are rendered non-adherent by applying to the surface which has or is given a coating of metal oxide liquid or semiliquid reagents which loosen the film of oxide.  The reagent may react with the metal to form hydrogen or may react with the metal to a greater extent than with any coating carried by or formed on the metal, or may produce by chemical reaction of its own components substances having these properties.  The reagent may also form or deposit hygroscopic substances on the interior surface of the container.  The ordinary coating of magnetic oxide of iron may be employed in the case of iron and steel containers, or these containers may be allowed to rust or be heated to form the coating of magnetic oxide.  The metal may also be given a coat of oxide paint or wash, or oxide may be suspended in part of the reagent and applied before the remainder.  The reagent may be a solution of an organic acid whose action is quickly inhibited.  Acid salts or substances reacting to form acids or acid salts may be used. Oxalic acid or sodium dihydrogen phosphate accompanied by a hygroscopic substance such as glycerine and water may be used, or orthophosphoric acid and a salt such as commercial chloride or nitrate of an alkali metal or ammonium, or alkaline earth metal, or iron, aluminium, manganese, zinc, or magnesium with water, such salt being hygroscopic and capable of reacting with the acid to liberate free hydrochloric or nitric acid.  Examples are given of various compositions of these substances.  Undue corrosion may be inhibited by adding colloids such as glue, gelatine, or casein. The asphalt &c. is filled into the container while the inner surfaces are moist.

Abstract: 320,430. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 23, 1928. Ink.-Bleachable printers' inks are made, with the aid of one or more black acid wool disazo dyes, such as Palatine black, Agalma black, Brilliant black, or Diamond black, in a waterinsoluble form, with or without an addition of other water-insoluble dyes or lakes, and removing water if present. The dyes are preferably employed in the form of their lakes, for example, the alkaline earth. magnesium, aluminium, or other difficultlysoluble lakes, or the free acids of the dyestuffs. precipitated from acid solutions, may be employed. The dyes may be advantageously employed in a condition of fine distribution by preparing them in the presence of dispersing agents, such as turkey red oil, glue, sulphonic acids or their salts, for example alkylnaphthalene sulphonic acids, salts of bile acids, saponine, and the like. Substrata, such as barium sulphate, blanc fixe, or aluminium hydroxide may also be employed. Papers printed with inks prepared in accordance with the invention are readily decolourized by the usual bleaching agents, such as chlorine or hypochlorites. In an example, Agalma black 10B is dissolved in water, precipitated by adding barium chloride solution, filtered, and mixed with a printing varnish, any water content being removed by warming or by means of drying- rollers.
