Title: Improvements in or relating to melamine-formaldehyde resins
IPC: C08L61/26
Filed: 1948-11-12
Abstract: In making a resinous moulding, laminating or surface finishing composition, melamine is condensed with formaldehyde in the molecular ratio of between 1 : 1 and 1 : 1.7 respectively, at a pH of 7 to 11 in an aqueous solution in which the total weight of melamine and formaldehyde is between 10 and 55 per cent.  For example, resin A is made by mixing melamine, formaldehyde and water, adjusting the pH to 8.2 by adding NaOH and refluxing until a sample thereof causes cloud formation in water at 0 DEG  to 10 DEG  C.; the mix is then cooled to 85 DEG  C. and the resulting syrup is concentrated in vacuum or by spray drying; resin B is made by refluxing a mixture of melamine, formaldehyde and water at pH 9.0 until a sample of the solution remains as such on cooling, at which point the pH is adjusted to 8.0 and the syrup is cooled and dehydrated.  In examples (1) and (2) a pulverized resin similar to A was mixed with a curing catalyst comprising p-toluene sulphonamide and phthalic anhydride, and zinc stearate as lubricant; the mix was dried and heated on rolls with subsequent pressure moulding; (3) a -cellulose sheets were impregnated with an aqueous solution of a resin similar to B and dried, whereupon a plurality of the impregnated sheets were stacked on steel plates and cured at 135 DEG  C. under pressure to form laminates; (4) a resin similar to A which had previously been advanced in condensation by milling with a catalyst, was made into a slurry with purified cellulose and water, a pulp pre-form prepared therefrom being cured and moulded under pressure; (5) an isopropanol solution of a castor oil modified glyceryl phthalate was added to a water-alcohol solution of a resin similar to A, and the pH was adjusted to 9.8-10.1, TiO2 was added and the mixture milled and finally ethyl alcohol was added to form a syrup which may be coated on surfaces of laminated articles and cured by heat and pressure; (6) ethyl alcohol, water, a pentaerythritol-adipate resin and a resin similar to A (which had been advanced in condensation) were ball-milled and the resulting syrup was coated on to printed pigmented paper, which had been impregnated with a melamine-formaldehyde resin, and dried, the coated sheets being then assembled and cured to form laminates; (7) birch veneers were impregnated with an aqueous solution of a resin similar to B, dried and cured, panels being prepared by assembling the treated veneers in pairs and pressure curing at 280 DEG  F.; (8) a resin syrup prepared from melamine, formalin (neutral) and water was mixed with a -cellulose and dried, the mixture being then milled with zinc stearate and phthalic anhydride and pressure moulded to form saucers and tea cups.  The compositions and articles made therefrom may be modified by addition before, during or after condensation of the resin of curing agents, plasticizers, opacifiers, pigments, dyes and fillers.  Specifications 466,096, 598,561, 601,308, 606,222 and 627,661 are referred to.

Title: Improved process in crystallization of insulin
Inventor: SCHLICHTKRULL JORGEN
IPC: A61K38/00
Filed: 1954-10-14
Abstract: A process of crystallizing insulin from an aqueous medium comprises adjusting the pH of the medium to between 5 and 7 in the presence of freeze dried amorphous insulin.  The medium may be produced by mixing an acid aqueous insulin solution and a basic solution which may contain crystallization promoting metals e.g. zinc, cobalt, nickel, cadmium, copper, iron or manganese, in amount about 0.4 per cent by weight of the insulin, and a buffer substance e.g. acetate, borate, citrate, phosphate, maleate or diethylbarbiturate buffers, to obtain the crystallization pH, or basic solution of insulin may be acidified to the required pH. The freeze dried amorphous insulin may be added to the basic solution prior to mixing with the acid insulin solution, or may be added to the medium after adjustment of the pH but prior to the commencement of crystallization, or may provide the whole insulin content of the crystallization medium.  The freeze dried amorphous insulin may be produced from crystalline insulin or amorphous insulin of similar purity which may be freeze dried in slightly acid or basic solution, or in a medium of similar composition to that of the crystallization medium.  The crystals obtained by the invention have mainly the same size and are suitable for use as seed crystals for the production of larger crystals.
