Title: Improvements in the manufacture and production of urethanes containing carboxyl or sulphonic acid groups
Filed: 1936-11-09
Abstract: Urethanes useful as assistants in the textile and related industries are prepared by reacting chlorocarbonic esters of abietinols with aliphatic, cycloaliphatic or aromatic aminocarboxylic acids, aminosulphonic acids or amine-sulphuric acid esters.  The abietinols comprise abietinol, di- and tetra-hydroabietinols and their substitution products, e.g. containing nitro groups or halogen. Second components specified are glycocoll, N-hydroxyethylaminoacetic acid, alanine, sarcosine, taurine, N-methylaminoethanesulphonic acid, N-hydroxyethylaminosulphonic acid, aminopropanesulphonic acid, monoethanolamine or ethylbutanolamine sulphuric acid esters, albumen degradation products, p-aminobenzoic acid and sulphanilic acid.  The reaction is preferably effected in an aqueous alkaline medium to which a small amount of a dispersing agent has been added.  If the products are not water-soluble, they may be made so by sulphonation. Examples are given of the condensation of the chlorocarbonic ester of abietinol with the sodium salt of sarcosine, the sodium salt of N-methyltaurine and the sulphuric acid ester of ethanolamine, in an aqueous solution of caustic soda; in the first two cases, a small amount of the condensation product of oleyl alcohol or lauryl alcohol (1 mol.) with ethylene oxide (20 or 10 mols. respectively) is present, whilst in the third case some of the product of a preceding operation is preferably added as dispersing agent. Specifications 381,204, 388,877, 425,370, and 450,467 are referred to.  The samples furnished under Sect. 2 (5) comprise the reaction products of (1) the chlorocarbonic ester of dihydroabietinol with cyclohexylethanolamine sulphuric acid ester, (2) the chlorocarbonic ester of dihydroabietinol with cyclohexylaminoacetic acid, and (3) the chlorocarbonic ester of trichloroabietinol with the acid sulphuric acid ester of ethanolamine, prepared in each case in caustic soda solution in the presence of a condensation product of ethylene oxide with oleyl alcohol.  The chlorocarbonic esters of abietinols are obtained by introducing phosgene at normal temperature into a solution of the abietinol in an inert solvent such as ethylene chloride, and evaporating the solvent in vacuo.  Trichloroabietinol results when abietinol is chlorinated.  Cyclohexylaminoacetic acid is prepared by condensing cyclohexylamine with chloracetic acid.

Abstract: 936,496. Hydraulic turbines. T. TILMAN. Sept. 4, 1961 [Sept. 7, 1960], No. 30834/60. Class 110 (3). In a method of generating power which is based on the relatively low temperatures which occur at high altitudes, a suitable liquid is evaporated in an evaporator disposed at a low level, the vapour is allowed to rise through insulated conduits to the high level where the vapour is condensed to liquid in a condenser. The liquid is then allowed to descend through conduits to the low level, the energy of the descending liquid being utilized to drive hydraulic turbines. The liquid discharging from the turbines is then passed to the evaporator and re-vaporized and the cycle repeated. In Fig. 1 an evaporator 11 is disposed in the sea and the liquid is evaporated, the vapour rising through insulated conduits 13<SP>1</SP> to the condenser 14 which may be disposed at an elevation of, say, 3000 metres. The liquid then passes downwardly through conduits 15 and drives the hydraulic turbines 16. The working fluid may be water, ammonia, or a refrigerant fluid such as fluorinated hydrocarbons. The condenser may be disposed at the top of a mountain; alternatively, the structure may be supported by balloons. Each insulated pipe may have a plurality of pipes, each containing a static fluid under substantial pressure, disposed therearound to provide a rigid structure.

Processes. - Artificial silk &c. of the hollow filament type, the filaments of which have collapsed or have been insufficiently distended during manufacture, is further distended by immersion in a liquid containing a gas in solution or a substance capable of producing gas, and then subjecting the treated material to a treatment such as heating or reduction of pressure, or to a chemical treatment, such as will cause generation of gas to take place. Thus, the material may be successively dipped into two solutions having a gas-developing action upon each other, or the gas may be derived from a solution of an unstable substance such as a diazo-compound. In examples, a hollow filament viscose silk is immersed in cold water saturated with air, and the temperature then raised to inflate the filaments; a hollow filament silk is soaked in sodium carbonate solution, is then treated with dilute acetic acid preferably saturated with air or carbon dioxide, and is finally washed with water similarly saturated. The inflated silk is preferably dried in closed chambers at 80-100‹ C.
