Title: Process for the manufacture of varnish having a base of albuminoid
IPC: C09D189/00
Filed: 1931-11-25
Abstract: The coagulation of a dispersion of an albuminoid, e.g. casein, in ethyl alcohol or other volatile solvent is retarded by adding acetic or other anhydride before the addition of a coagulant, such as a solution of trioxymethylene in an alcohol such as methyl alcohol, with, if desired, traces of caustic potash.  After adding the anhydride, the dispersion may be electrolysed in presence of hydrogen peroxide.ALSO:Varnishes are produced from solutions or dispersions of albuminoids, e.g. casein, by the addition of acetic or other anhydride to act as a retardant before adding a coagulant such as a solution of trioxymethylene in methyl alcohol.  After the addition of the anhydride, the dispersion may be electrolyzed in the presence of hydrogen peroxide till evolution of gas ceases, when a further addition of the anhydride is made, or water-immiscible alcohols, such as iso-amyl, butyl, or benzyl alcohol may be added, some of the ethyl alcohol originally used being allowed to evaporate.  Glycerine or other plasticizer, and a solvent mixture consisting of amyl acetate, acetone, terpinol and turpentine, may also be added.

Patent GB-868421-A (GB)
Title: Improvements in or relating to trimethylolalkane products
IPC: C07C31/18
Filed: 1958-10-14
Abstract: Trimethylolalkanes are recovered from aqueous reaction liquors resulting from the reaction of formaldehyde with an aliphatic aldehyde containing from 3 to 5 carbon atoms in the presence of an alkali, by extracting the reaction liquor with a water-immiscible solvent to form a solvent solution of the extracted material, separating the solvent solution from the reaction liquor, contacting the separated solution with water to form an aqueous solution of the extracted material and separating the solvent, contacting the aqueous solution with a cation-exchange material and an anion exchange material, and evaporating the effluent from the ion exchange treatment to recover a trimethylolalkane. Suitable solvents are, for example, alcohols having 4-7 carbon atoms, particularly amyl alcohol, and ethyl acetate.  It is desirable before extracting the reaction liquor to concentrate it by evaporating some of the water. Preferably the extraction is carried out at a temperature between 60 DEG  and 90 DEG C.  In a preferred method of carrying out the process the separated solution is steamdistilled to form the aqueous solution of the extracted material but, alternatively, the separated solution may be contacted with water and the aqueous phase separated, for example, by decantation.  The aqueous reaction liquors used as starting materials may contain, in addition to the desired trimethylolalkane and the alkali metal formate, the following compounds:-  <FORM:0868421/IV (b)/1> trimethylolkane, <FORM:0868421/IV (b)/2> monocyclic formal of trimethylolalkane, <FORM:0868421/IV (b)/3> linear formal or trimethylolakkane, and <FORM:0868421/IV (b)/4> in which R is an alkyl radical having 1-3 carbon atoms.

Abstract: 1,111,501. Ring-spinning apparatus. M. GILLONO and P. ALBERTO. 30 July, 1965 [18 Aug., 1964 (2)], No. 32816/65. Heading D1D. In ring-spinning apparatus, compressed fluid is directed circumferentially around the spindle to assist movement of the traveller, means being provided for controlling the velocity of the fluid. The arrangement aims to reduce the occurence of breaks in the yarn arising from the sticking of the traveller on the ring as a result of the direction in which the yarn is pulled when winding is taking place on those parts of the package which have small diameters. As shown, a channel formed by a guide 6 enveloping the ring over part of its circumference is supplied with compressed air from a jet 9. The air, which may carry a lubricant for the traveller or materials for treating the yarn, may act directly on the traveller, or on a member driving the traveller by contact or magnetically. The supply of air can be varied during the wind, the nozzle accordingly may be adjustable or a regulator may be provided in the line supplying the nozzle the guide may be disposed substantially outside or inside the ring or below it, in all cases part at least of the traveller will lie within the channel formed between the ring and the guide. There may be more than one jet or inlet for the fluid; a second channel exterior of the first may be filled with compressed air which can be directed into the first channel.
