Title: Improvements in the production and treatment of textile and other materials made of or containing cellulose derivatives
IPC: D01F11/02
Filed: 1929-05-31
Abstract: 334,853. Dreyfus, H. May 31, 1929. Yarns &c., treating with liquids.-In the manufacture of threads, filaments, or the like of cellulose derivatives, these are subjected to the action of organo-mineral acids of a. concentration of 20 per cent or higher, preferably 30 to 50 per cent, although concentrations up to 100 per cent may be employed in some cases. The acids are such as are obtainable theoretically by replacing one or more, but not all, of the hydroxy groups of a di. or poly basic mineral acid by organic radicles. Examples of such acids are methyl or ethylene sulphonic acid, propyl 1.2 or 1.3 di-sulphonic acid, sulpho-acetic acid, sulpho-succinic acid, ethanol sulphonic acid, benzyl sulphonic acid, benzene sulphonic acid, phenol sulphonic and disulphonic acids, sulpho-salicylic acid, sulphophthalic acid, naphthalene and naphthol sulphonic acids, dimethyl phosphinic acid and nitro-phenyl phosphinic acid. Substances exerting a solvent or solute action may be added, or the organomineral acid may contain one or more substituent groups, such as hydroxy or amino groups, which induce such actions. The organo-mineral acid may be dissolved in water, an organic liquid such as alcohol, or a mixture. During treatment the threads may be under tension or stretched or may be allowed to shrink. After the treatment the material is preferably freed from acid by washing with water or aqueous alkali such as ammonia. Substantial hydrolysis of cellulose esters is preferably avoided. The temperature of treatment may range from 0 C. to somewhat above atmospheric. In one of the examples, acetate filaments or threads are treated with a 45 per cent solution of methyl sulphonic acid, with stretching. The treatment of cellulose formate, propionate, and butyrate, and of methyl, ethyl, and benzyl cellulose is also mentioned. The process is applicable to materials containing cellulose derivatives in admixture with other fibres such as cotton.

Title: Improvements in the manufacture and production of valuable hydrocarbons by destructive hydrogenation of coal suspensions, tars, mineral oils and the like
IPC: C10G1/08
Filed: 1930-06-02
Abstract: In the destructive hydrogenation of liquid carbonaceous materials containing a solid catalyst in suspension, the carrying down of the catalyst by precipitation of asphalt is prevented by avoiding the simultaneous presence of asphaltic substances and hydrocarbons rich in hydrogen which may be light or heavy hydrocarbons.  Light benzines are removed from the initial material before hydrogenation, and when formed during the reaction are removed by the use of a rapid flow of hydrogen. Heavy paraffins may be removed from the reaction mixture by withdrawing a part of it, cooling, filtering or centrifuging, and returning the liquid portion to the reaction.  Asphaltic substances may be removed from initial materials by distillation.

Abstract: 474,639. Mounting motors. LORD, H. C. June 19, 1936, No. 17066. Convention date, June 24, 1935. [Class 79 (iii)] [Also in Group XXXII] A resilient mounting comprises a body of resilient material superficially united by faces substantially at right-angles to each other to similarly -arranged faces displaced laterally from each other but fixed respectively relatively to the load to be supported and to a supporting base so that the major portion of the load is sustained by the resilient material in shear and shear resistance is also offered to thrusts in directions parallel to the face of the supporting base. As shown in Figs. 14 and 17, a resilient mounting for a vehicle engine comprises an apertured base-plate 10 adapted to be secured, e.g. to a transverse frame member of the vehicle and a loadsupporting plate 13 extending with clearance through the aperture in the plate 10 and at right-angles thereto, the plates being connected by a rubber pad, preferably bonded during vulcanization to the plates in order to support the major portion of the load in shear. Normally the upper and lower faces of the rubber are formed convex and concave respectively and are engaged by flat snubbing and rebound plates 19, 23, Fig. 17, fastened to the plate 13 and adapted under heavy shocks or increase in load to flatten the adjacent end of the rubber so that the supporting force is due also to the compression of the portions of the rubber overlapping the plate 10. In a modification the rubber has extensions adapted to be compressed by an extension of the plate 19 in order ultimately to increase the supporting force. Several arrangements of mountings constructed as described above for supporting a vehicle engine are shown. Fig. 6, for example, shows the front of an engine supported on a strut 34 by a single mounting 8, while Fig. 7 shows the rear of the engine supported on a transverse frame member 33 by two inclined mountings 9.

Patent GB-755511-A (GB)
Title: Azeotropic distillation process
IPC: C07C7/06
Filed: 1953-06-22
Abstract: Close boiling hydrocarbons are separated by azeotropic distillation using a perfluoromonocarboxylic acid and an aqueous solution thereof as auxiliary agent.  Preferably the acid has a boiling point within 35 DEG C. of the 50 per cent boiling point of the mixture, perfluorobutyric acid (B.P. 122 DEG C.) being used for separating ethyl benzene and xylenes (B.P. 137 DEG C.) and trifluoroacetic acid (B.P. 72 DEG C.) for separating cyclohexane and benzene (B.P. 80 DEG C.).  The quantity of acid should be sufficient to form an azeotrope with a substantial proportion of the hydrocarbon to be distilled off. Water may be used in a proportion of 0.5 per cent up to the saturation value in the hydrocarbon-acid mixture at distillation temperature.  The presence of water increases the relative volatility of the hydrocarbons to be separated.  The condensate usually separates into two layers which are then treated in the usual manner. In examples: (1) ethyl benzene and p-xylene are distilled in a single stage equilibrium still using perfluorobutyric acid as auxiliary agent.  Figures are given for distillate and bottoms composition yield and a  value.  The a  value for ethylbenzene and m-xylene is also given and the boiling points and compositions of the various binary azeotropes and the various solubilities and critical solution temperatures.  (2) Eethyl benzene and m-xylene are distilled in a single stage usuing perfluorobutyric acid.  a  values for various quantities of water are given.  (3) Benzene and cyclohexane are distilled using trifluoroacetic acid as auxiliary agent.  Figures are given for overhead and bottoms compositions, recovery and relative volatility.  The separation of mesitylene from methyl-ethylbenzenes and of cymene from butyl benzenes is also referred to.
