Title: Improvements in or relating to liquid coating compositions
IPC: C08G18/08
Filed: 1958-06-13
Abstract: A stable, air-drying liquid organic coating composition consists essentially of a solution in a volatile organic solvent of a polyurethane reaction product of (a) 1 hydroxyl equivalent of polyester having a molecular weight of 500 to 3000, an acid number of not more than 5 and an average of 2 to 3 hydroxyl groups per molecule, (b) 0-1 hydroxyl equivalent of saturated aliphatic diol containing 2-6 carbon atoms per molecule, (c) 0-6 hydroxyl equivalents of saturated aliphatic triol containing 3-6 carbon atoms per molecule and (d) organic diisocyanate in an amount sufficient to provide 1.2 to 2.0 isocyanate groups for each hydroxyl group provided by (a), (b) and (c), the said reaction product having been made in the presence of at least 0.003% by weight (based on the diisocyanate) of chlorine in the form of a compound which produces chlorine ions and is acidic in water.  The chlorine can be present as carbamyl chloride, acyl chloride, hydrogen chloride, phosgene, benzoyl chloride, o-chlorobenzoyl chloride and quaternary ammonium chlorides. The polyester can be prepared from phthalic, adipic, azelaic, maleic and dimerised vegetable oil fatty acids; ethylene glycol, diethylene glycol, propylene glycol, or tetra, penta or hexamethylene glycols are suitable diols; glycerol, trimethylol ethane or propane, and hexanetriol are suitable triols.  The reaction product can be prepared in the absence or presence of solvents, for example methyl isobutyl ketone or ethyl acetate and their mixtures with hydrocarbons such as toluene, mineral spirits, xylene, and hexane. The compositions can be pigmented with metal oxides, sulphides, sulphates, silicates, chromates, metal powder or flake, carbon black, iron blues and organic dyestuffs.  Hardeners, softeners, curing catalysts and surface active agents can be added.  In examples, the compositions are applied by brushing, spraying or flowing to surfaces of wood, e.g. flooring, metal or glass, and allowed to dry in moisture-containing air.

Title: Terephthaloylamino acids, their salts and esters, and processes for the production thereof
IPC: A61K49/04
Filed: 1958-06-18
Abstract: The invention comprises tetraiodo-terephthaloyl-amino acids of the general formula <FORM:0836748/IV (b)/1> (wherein R is a hydrogen atom or lower alkyl radical and n is 1 or 2), and lower alkyl esters and metal- and amine-salts of the acids.  The invention also comprises the process of producing the above compounds by condensing tetraiodo-terephthaloyl dichloride with an ester or salt of the appropriate amino acid.  These tetraiodo-terephthaloyl derivatives are efficient X-ray contrast agents (see Group VI).  In Example 1, tetraiodo-terephthaloyl dichloride is dissolved in dimethyl formamide, and the solution is mixed with a solution of glycine in aqueous sodium hydroxide.  The mixture is stirred for 2 to 4 hours on a steam-bath.  After cooling to 60 DEG  C., hydrochloric acid is added, whereupon tetraiodo-terephthalic acid diglycide is precipitated.  Example 2 describes the preparation of the corresponding diethyl ester. Example 3 describes the preparation of the bis-diethanolamine salt by dissolving the free acid in somewhat more than the theoretical quantity of 50% aqueous diethanolamine, and precipitating the salt with ethanol.  The example also relates to the sodium, lithium and bis-N-methyl-glucamine salts.ALSO:The invention comprises tetraiodo-terephthaloyl-amino acids of the general formula <FORM:0836748/VI/1> (wherein R is a hydrogen atom or lower alkyl radical and n is 1 or 2), and lower alkyl esters and metal- and amine-salts of the acids (see Group IV (b)).  The compounds are efficient X-ray contrast agents.  In urography, a solution of the sodium, diethanolamine or glucamine salt can be injected intravenously.  The compounds may also be used in bronchography and hysterosalpingorraphy.  The compounds may be administered orally in the form of solutions, suspensions, tablets or capsules.  In bronchography, the esters are preferably used in suspension.  It is possible, however, to use salts of the acids provided thickening agents such as methyl cellulose, gelatine or dextran are used.

Abstract: 506,109. Valve modulating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 1, 1938, No. 19613. ,Convention date, July 3, 1937. [Class 40 (v)] A modulation circuit arrangement comprises two valves with at least three grids, the carrier frequency being applied between the cathodes and control grids 1, 1a in parallel, while the modulating frequency is applied to the distribution grids 3, 3a, in push-pull. Modulated output is taken off, by means of the push-pull or divided primary transformer T, from the anodes and positively biassed grids 2, 2a the output circuits of each valve being cross-connected in parallel.' The degree of carrier suppression obtained in the output is controlled by the bias of grids 3, 3a. This circuit has the advantage over a single valve arrangement that each half of the output transformer is loaded with both a screen grid and an anode, and differences in their internal impedances do not produce unequal loading of the two halves. The ends of the output transformer may be connected to another positively biassed grid located between grids 2 and 3 in each valve. Specification 491,805 is referred to.

Title: Mine shaft transport installations
IPC: E21F13/00
Filed: 1960-06-03
Abstract: 891,780. Mine cage apparatus; winding gear. STAMICARBON N. V. June 3, 1960 [June 3, 1959], No. 19803/60. Classes 78 (3), 78 (4) and 78 (5). Equipment of relatively great length is transported to and from a mine shaft station by means of a cage 3 hinged to the upper part of a frame 1 coupled to shaft-hoisting gear 4, 5. When the cage is lowered to the position in full lines in Fig. 1, the lower end of the cage is swung into the station as shown in dotted lines by means of a rope 11 and appropriate powered haulage means 10, a safety device preventing the means 10 from swinging the cage beyond a certain maximum inclination to the vertical. This ensures that the cage may be pushed or lowered into horizontal position and supported directly or indirectly on the station floor by further downward movement of the frame 1 (Fig. 2). The means 10 may comprise a locomotive and the safety device resides in automatic uncoupling. As shown however, the means 10 comprises a winch (Fig. 5) having a motor-driven shaft 17. A sleeve 21 in slidable splined connection with the shaft 17 has screw-thread connection with the winch drum 20. Teeth 22 carried by the sleeve 21 may have driving engagement with teeth 23 carried by the drum. In operation, the winch is operated by its driving motor to draw the cage to the position shown dotted in Fig. 1, and then the motor drive is terminated. Decrease in load on the rope 11 enables a further rope 19 wound on a second drum portion 24 of the drum 20 to turn the drum under the action of a weight (Fig. 6, not shown) to take up the slack of the rope 11 as further lowering of the frame 1 proceeds and the cage is lowered to the position of Fig. 2. During this rotation of drum 20 due to the screw connection between the sleeve 21 and the drum 20, the teeth 22, 23 are brought out of engagement. When the cage 3 is to be returned to the frame 1 the reverse process takes place. A hook 25 then results in automatic locking of the cage in the frame 1. The hook 25 may be constructed so that the rope 11 cannot be removed until this has taken place. Safety means is provided to ensure that while the shaft door is open the hoisting engine cannot be operated. The cage 3 may have a cover having a lock which is arranged so that when the cover is opened current for creep speed of the hoisting engine is cut-out. The pivot 2 between the frame 1 and the cage 3 is constructed to permit a longitudinal movement of the cage 3 in the position shown in Fig. 2.
