Title: Improvements in or relating to the manufacture of foam-generating substances
Inventor: JONASON MICHAEL
IPC: A62D1/02
Filed: 1954-03-11
Abstract: A foam-generating substance comprises an aqueous solution of the hydrolytic degradation products of a protein and a substance capable of yielding sulphite ions in aqueous solution to inhibit, or reduce the tendency of, the formation of a precipitate when an aqueous solution of the substance is maintained at a high atmopheric temperature or stored for a prolonged period.  The protein, e.g. soya bean protein, casein, fish waste, keratin, horn or hoof meal, may be in a fine state of division, e.g. 16 mesh or less, and may be hydrolysed in an aqueous solution or suspension of ammonia, or an alkaline earth metal or alkali metal hydroxide or oxide, e.g. caustic soda, magnesium oxide and hydroxide. in a concentration from 0.1 to 0.5 grams sodium hydroxide (or its equivalent in other alkalies) per gram of protein.  The sulphite ions, which may be present within the range introduced by the addition of 0.04 to 0.07 gram anhydrous sodium sulphite per gram nitrogen in the hydrolysate, may be provided by addition of a sulphite, bisulphite or hydrosulphite, e.g. of an alkali metal, alkaline earth metal or ammonia, to the hydrolysate, which may then be filtered and from which undesirable gases may be expelled, prior to neutralization by the use of, at least in part, an aliphatic monocarboxylic acid such as a fatty acid which may contain not more than six carbon atoms, e.g. formic, acetic and propionic acid.  A foam-stabilizing agent, e.g. ferrous or copper salts such as the sulphate and chloride, may be added to the hydrolysate after the addition of the sulphite ions, the addition, together with that of an alkali to maintain a constant pH, are led in below the surface of the hydrolysate.

Title: Milling process for producing ª‡-form copper phthalocyanine pigments
Inventor: HARPER HAROLD ROY
IPC: C09B67/00
Filed: 1964-02-24
Abstract: An essentially a -form copper phthalocyanine is made by milling by agitation with particulate grinding elements a slurry of a crude copper phthalocyanine in an aqueous medium which contains a surface-active agent in amount not more than 5% of the weight of copper phthalocyanine, said agitation being continued until at least 90% of the copper phthalocyanine is in the a -crystal form. The term "copper phthalocyanine" includes chloro derivatives of copper phthalocyanine containing up to 10% of chlorine.  It is advantageous to increase the surface area of the product by milling in an aqueous solution of a surface-active agent used in amount greater than that described above or in an organic liquid such as methanol or ethanol. The product may be used in paste form or may be isolated in solid form by flocculation followed by filtration, washing and drying. Non-flocculating pigment compositions may be obtained by carrying out the second stage of the process in the presence of a basic phthalocyanine derivative of the type used in Specifications 972,805, 1,058,226, 1,082,945 and 1,082,967.  A pigment composition comprising a fine dispersion of a -form copper phthalocyanine (which may contain up to 10% chlorine) in an aqueous solution of a resin salt is obtained by carrying out the second stage of the above process using as surface-active agent a water-soluble salt of a resin substance (e.g. potassium rosinate). The dispersion may then be flocculated by means of an electrolyte (e.g. an acid) which also precipitate the resinous substance.
