Patent GB-755827-A (GB)
Title: Surface-active sulpho-betaine compounds
Filed: 1952-06-30
Abstract: The invention comprises oil-soluble sulphobetaines having the general formula <FORM:0755827/IV(a)/1> in which R1 and R2 are C9-18 alkyl groups Ar is an aryl hydrocarbon nucleus, R3 is a C1-7 alkyl group and R4 is a C1-7 alkylene or cycloalkylene group. They may be prepared by reacting an amount in excess of a molar proportion of a C9-18 alkyl aryl methylene halide with an N-alkyl amino alkane sulphonate, if desired, in the presence of a neutralizing agent. Preferably, at least 2 molar proportions of the methylene halide are used.  The aryl groups of the methylene halide reactants may be derived, for example, from benzene, toluene, xylene, mesitylene, naphthalene or anthracene.  The C9-18 alkyl nuclear substituents may be derived from halogenated hydrocarbons, aliphatic alcohols and olefines including cracked petroleum fractions and polymers of ethylene, propylene and butylene.  The methylene halides may be obtained by chlor-methylation of the nuclear alkyl derivatives of the aromatic hydrocarbons.  Specified amino sulphonate reactants are sodium N-methyl or -ethyl amino ethane sulphonate, potassium N-ethyl-2-amino-propane sulphonate, sodium N-butyl amino butane sulphonate and sodium N-hexyl amino-cyclohexane sulphonate.  The products are surface-active and may be used as dispersing and anti-rust additives in fuel and lubricating oils.  In examples (1) sodium N-methyl taurate is refluxed with p-nonyl (propylene trimer) benzyl chloride in aqueous ethanol yielding N,N-di-(p-nonyl benzyl)-N-methyl-taurine; (2) sodium N-methyl taurate is refluxed in ethanol with p-dodecyl (propylene tetramer) benzyl chloride, using NaHCO3 as neutralizing agent, yielding N,N-di-(p-dodecyl benzyl)-N-methyl taurine; (3) N,N-di-(p-keryl benzyl)-N-methyl taurine is prepared similarly using a p-dodecyl benzyl chloride whose alkyl group is derived from a C12 kerosine distillate; (4) sodium 2-(N-ethylamino)-propane-1-sulphonate and p-dodecyl-methyl-benzyl chloride are refluxed in aqueous isopropanol containing NaHCO3 yielding 2 - [N,N - di - p - dodecylmethylbenzyl)-N-ethylammonium]-propane-1-sulphonate.

Title: Improvements in or relating to vacuum brake apparatus for railway trains or vehicles

Filed: 1923-06-28
Abstract: 218,103. Peters & Co., Ltd., G. D., and Rawlings, V. P. June 28, 1923. Fluid-pressure.-In an emergency valve for use in vacuum brake apparatus an electrically propelled vehicle of the kind having a main chamber connected to the train pipe, a second chamber connected to the deadman's valve at the master controller, and also, through a restricted port, to the exhauster, and a diaphragm operated valve which is opened to admit air to the train pipe when the relaxation of the driver's grip on the controller allows the deadman's valve to open, the valve casing comprises only two chambers 1, 2 separated by the diaphragm 3, which operates the air-admission valve 10 and forms an air-tight joint between the members 1, 2. In the form shown in Fig 1, the chamber is connected at 8 to the driver's valve and at 9 to the train pipe, and the chamber 2 is connected at 4 to the deadman's valve and through the restricted port 5 to the releasing reservoir or the auxiliary train pipe. With the driver's valve in the running or release position, vacuum exists in both chambers 1. 2, and the valve 10 is held closed. When, however, the chamber 2 is supplied with air from the deadman's valve, the diaphragm 3 rises and opens the valve 10 to admit air to the train pipe to apply the brakes, and at the same time closes a valve 7 to cut off the train pipe from the driver's valve. The form shown in Fig. 3 is adapted for use with brake apparatus having a single train pipe and electrically-operated valve for isolating the train pipe from the electrically-operated pumps when the brakes are applied or when the driver relaxes his grip on the knob of the deadman's valve. The valve 7 may, therefore, be dispensed with, and the lower end of the spindle 14 is guided through a perforated partition 23. The outlet 5 is now connected through a non-return valve 26 either to the exhauster or to the train pipe. A cover 21 is provided to protect the valve 10 and the. stem 14 is extended so as to project through it, so that the valve may be manually seated should it fail to close.
Patent GB-425981-A (GB)
Title: Improvements in or relating to plastic shortenings
IPC: A23D9/013
Filed: 1933-06-13
Abstract: A process for the production of plastic shortening comprises hydrogenating an unsaturated fatty oil until it has an iodine value of about 40 or lower, reacting the hydrogenated oil with glycerine in sufficient proportion to yield a hard fat containing at least 19 per cent, preferably about 22 per cent, combined glycerine but insufficient to form solely the monoglyceride.  The product is then intimately mixed with a softer fat or fatty oil of the triglyceride type, the proportion of the hard fat being not less than about 2 per cent and preferably between 2-6 per cent. A small quantity of a soap and/or a free fatty acid, as described in Specification 414,916, [Group VI], may be added to the shortening.  The following fatty oils are specified as the source of the hard fat or for the triglyceride portion of the shortening viz.: cottonseed, peanut, sesame, corn and soyabean oils; coco-nut oil, palm kernel oil and similar oils derived mainly from lauric acid may be used if blended with an unsaturated oil of lower congealing point to ensure proper plasticity.  The shortening may be used in the production of sweet baked goods as described in Specification 425,982.  Specification 425,980 also is referred to.  The Specification as open to inspection under Sect. 91 also describes plastic shortening comprising a mixture of any hard fat containing not less than 19 per cent combined glycerine, including monoglycerides, together with a softer fat or fatty oil of the triglyceride type, and refers to oleo-stearin, animal fats such as lard or tallow, and marine-animal oils such as whale or pilchard oil, as the source of the hard fat.  Numerous examples are given e.g. a shortening is made by mixing 85 per cent cottonseed oil, 9 per cent hydrogenated cottonseed oil of 15 iodine value and 6 per cent of the monoglyceride of this hydrogenated oil.  This subject-matter does not appear in the Specification as accepted.

Patent GB-170302-A (GB)
Abstract: 170,302. Chemische Fabrik vorm. Sandoz. Oct. 14, 1920, [Convention date]. Addition to 125,396, [Class 2 (iii), Dyes &c.]. Medicinal preparations.-Salts of the principal alkaloid of ergot, described in Specification 140,056, [Class 2 (iii), Dyes &c.], and now designated " ergotamine," are obtained by action of acids on the pure free base. The acid is added to a solution of the base in an inert organic solvent miscible with water, such as ethyl or methyl alcohol, or acetone, whereupon the corresponding salt is usually precipitated in crystalline form; the acid salts are readily transformed into salts of lower acid content which may also be obtained by using in the above process a solvent not miscible with water, such as ether, chloroform, or benzene, and recrystallizing the precipitated salt from a convenient solvent. When aqueous solutions of the salts are required, ergotamine, dissolved in an organic solvent, is added to water containing the necessary acid; alcohol and glycerine may be added as preservatives. In order to avoid oxidation, the preparation and storage of the products may be carried out in an atmosphere free from oxygen. In examples the preparation is described of the sulphates, hydrochloride, and tartrate of ergotamine, and of solutions of the citrate in aqueous common salt solution and of the base in physiological salt solution containing carbon dioxide. The products are suitable for parenteral administration. The Specification as open to inspection under Sect. 91 (3) (a) states also that an alkaloidal preparation rich in ergotamine may be used as starting material and that the formation of salts may serve for the separation or ergotamine from the impurities in crude ergot. The preparation of the salicylate and citrate of ergotamine is described. This subject-matter does not appear in the Specification as accepted.
