Title: Improvements in and relating to the spinning of viscose
IPC: D01F2/10
Filed: 1957-09-11
Abstract: In the manufacture of viscose yarn, incrustation of the spinneret orifices is inhibited by incorporating into the viscose at any stage of its preparation and/or into the acid coagulating bath a quaternary ammonium compound having the formula <FORM:0840902/IV(a)/1> where R is an aliphatic hydrocarbon radical having 6-22 carbon atoms, R1 is an alkylene radical having 2 or 3 carbon atoms, R11 is an alkyl radical having 1-3 carbon atoms, X is a halogen atom and x and y are integers each being at least one and having a sum equal to between 2 and 50.  The quaternary ammonium compounds may be prepared by reacting primary aliphatic amines having 6-22 carbon atoms in the molecule with ethylene or propylene oxide and reacting the tertiary amines so produced with an alkyl halide having 1-3 carbon atoms. Suitable primary aliphatic amines are hexylamine, octylamine, decylamine, dodecylamine, tetradecylamine, hexadecylamine, octadecylamine, octadecadienylamine and octadecenylamine and mixtures of these compounds resulting from the amination and reduction of fatty acids produced by the hydrolysis of animal and vegetable oils, such as tallow, coconut oil, soybean oil and cottonseed oil, and by distillation of tall oil.  When added to the viscose, 0.02-0.5% by weight, based on the weight of the viscose, of the quaternary ammonium compound is preferably incorporated and when added to the acid coagulating bath 0.02-0.1% by weight may be used.  The quaternary ammonium compound may be added at one or more of the viscose preparation stages, as for example, to the chemically prepared wood pulp used in the manufacture of the viscose, or prior to or during shredding of the alkali cellulose, or to the cellulose xanthate crumbs before or during the dissolving step, or to the dissolved cellulose xanthate before or after filtration.  The coagulating bath may contain sulphuric acid, sodium sulphate and zinc sulphate.

Abstract: 308,741. Schering-Kahlbaum Akt.- Ges., (formerly Chemiscbe Fabrik auf Actien vorm. E. Schering), and Jordan, H. Oct. 28, 1927. Addition to 273,684. 4 4' - Dimethyl - 2 : 2' - dihydroxydiphenyldimethylmethane is prepared by condensing mcresol with acetone in the presence of gaseous hydrochloric acid at ordinary or less than ordinary temperature, spontaneous heating being repressed, e.g. by cooling or by dilution with a solvent or by the use of only a small concentration of condensing agent. Instead of gaseous hydrochloric acid, a material may be used as condensing agent which liberates hydrochloric acid in contact with the water formed, e.g. phosphorus oxychloride or an anhydrous metallic halide of the. Friedel-Crafts type. A water-binding agent, such as anhvdrous magnesium sulphate or an acid anhydride, is preferably added to the reaction mixture, or a condensing agent is employed which combines with the water formed. In the case of the use of hydrochloric acid, it is advantageous to saturate the two reactants separately and then to mix them under strong cooling. Examples are given.

A hydraulic door locking mechanism for a motor vehicle comprises a manually operable diaphragm piston 7 and a speed-responsive diaphragm piston 17 each adapted to pressurise fluid in a common hydraulic line H supplying slave cylinders 4 for actuating a number of locking bolts 9 simultaneously, the piston 15 being acted on by a rod 3 which is connected to mechanism (not shown) driven from the gear box of the vehicle whereby movement of piston 15 to the position 16 occurs when the speed of the vehicle exceeds a predetermined value. The manually operable piston 7 is secured to a rod 13 movable by a push button 10, a spring-loaded ball (11, Fig. 2, not shown) being engageable with a recess in the rod 13 in the depressed position of the push button to hold the bolts 9 in the locked position with a force sufficient to overcome the effect of release springs 18. When the vehicle is being driven, however, movement of the piston 15 to the position 16, upon exceeding the predetermined speed, overcomes the effect of the spring-loaded ball to return the push button 10 and piston 7, so that when the vehicle subsequently stops the bolts return to released position. Thus, in the event of a crash the occupants of the vehicle are not locked in. The vehicle can also be locked externally by key cylinders 5D, 5G on opposite sides of the vehicle which are coupled to the piston 7 by lost-motion couplings 25, 27 and 26, 28, respectively, a pinion 20 and a rack formed on the rod 13.
