Title: Improvements relating to vestibules and like connecting structures for railway and like vehicles
IPC: B61D17/22
Filed: 1937-04-28
Abstract: 480,497. Collapsable vestibules between vehicles. BUGATTI, E. April 28, 1937, No. 12146. Convention date, April 29, 1936. [Class 103 (iv)] In a vestibule connection between railway cars of the kind comprising a belt or a tubular sleeve which by its elasticity preserves an unbroken contour along the length of the train, the belt or sleeve is provided along one or both vertical edges with a bead or welt which cooperates with means on the end of the carriage for securing the belt in position. As shown in Figs. 1 and 3, a substantially rectangular frame D attached to the end of the carriage A forms a channel F adapted to receive the welt C of the belt B, a cable H passing internally through the welt being tightened by screw means I<11> for drawing the welt into the channel F and simultaneously tensioning the belt. Both ends of the belt may be equipped with tightening means, and such ends may meet or overlap so as entirely to exclude dust or draughts. In a modification, Fig. 6, the frame N in which the channel M is formed may be adjusted in relation to the vehicle by screw-and-nut mechanism O, P, additional tension being thus applied to the belt B. When the elastic connection is in the form of a tubular sleeve, the edges of the same may constitute extensible beads adapted to be slipped over fixed frames on the vehicles, or they may be non-extensible and adapted to be engaged by frames composed wholly or partly of foldable or removable segments.

Patent GB-592116-A (GB)
Title: Stabilized alumina and preparation thereof
IPC: C01F7/141
Filed: 1945-05-22
Abstract: Stabilized alumina is produced by precipitating an alumina gel containing a small proportion of basic aluminium sulphate, reacting the gel with a solution of an alkali (preferably potassium) silicate to replace the sulphate by silicate and washing to remove alkali sulphate.  One to 15 per cent. silica may be present in the product, and a slight excess of alkali silicate may be used to give a product containing 0.03 to 1 per cent. of alkali metal.  The gel is precipitated by treating alum or aluminium sulphate with sodium or ammonium hydroxide or the like, or by treating an alkali, say sodium, aluminate with sulphuric acid or ammonium sulphate or mixtures thereof at room or elevated temperatures and in concentrations of not more than 4 normal, to give a final pH of less than 9.8, for example, 9.1.  The gel may be washed free from sulphate iron, filtered, and slurried with a solution of potassium metasilicate, prepared by dissolving silica in the alkali metal hydroxide, in at least equivalent amount to the remaining sulphate.  The slurry is filtered and washed until free from sulphate, dried and calcined for, say, three hours at 500 DEG  C.  The product is suitable for the dehydration of liquids and gases and for decolorizing and refining of oils, syrups, and glycerine, as well as for use as a catalyst or carrier in multi-component catalysts.  A concentrated solution of boric acid may be impregnated in the gel before drying and calcining, when the resultant material containing, e.g., 23 per cent. boric oxide, is suitable for catalytic cracking of hydrocarbon oils, for example, at 500 DEG  C. and atmospheric pressure.ALSO:The decolorizing and refining of syrups may be carried out using a stabilized alumina, comprising a precipitated alumina gel containing a minor amount, e.g., 1 to 15 per cent., of silica and preferably 0.03 to 1 per cent. of an alkali metal.

Abstract: 1,221,125. Crystallizing sugar. J. PFEIFER and A. LANGEN [trading as PFEIFER & LANGEN]. March 18, 1968, No.13016/68. Heading C6B. A suspension for inoculating sugar syrups to promote crystallization during boiling in vacuum pans, comprises a fondant paste of saccharose micro-crystals between 5 and 10 microns in size suspended in a carrier solution. The carrier solution is preferably formed by mixing an aqueous saturated solution of saccharose at room temperature with a similar solution of commercial glucose, preferably in the ratio 60:40. The suspension preferably comprises equal parts by weight of the fondant paste and the carrier solution. The suspension may be made by mixing a saturated saccharose solution and a saturated commercial glucose solution at room temperatures in a ratio of 70:30, thickening the mixture up to a boiling point of 116‹C., cooling to 60‹C. whilst at rest, then further cooling rapidly until vigorous mechanical agitation. An apparatus in which the various stages are controlled automatically is shown in Fig.3 and is described fully in Specification 1, 221,124. Briefly the apparatus comprises a vacuum boiler 1 into which a measured quantity of sugar syrup is passed by emptying the measuring tank 2. When tank 2 is emptied, float switch K2 causes valve 4 to open and admit steam into the boiler 1. When the viscosity of the syrup reaches a predetermined level, viscometer 7 causes valve 10 to open and discharge the inoculation suspension from tank 9 into boiler 1. Heating continues and the viscosity held constant for a period, the viscometer 7 controlling the supply of either hot water or syrup from devices 12 or 13 to achieve this. The viscometer is programmed to then allow the viscosity to rise to a predetermined amount, which completes the cycle.

Title: Improvements in or relating to the manufacture of polyhydric alcohol-polybasic acid resins
IPC: C08G63/46
Filed: 1936-05-08
Abstract: Relates to resins of the type in which a polyhydric alcohol, a polybasic acid or anhydride, and a monobasic acid or its glyceride are condensed, the quantity of polycarboxylic acid exceeding that of monobasic acid.  A resin of this type is prepared by first condensing part of the polyhydric alcohol and part of the polybasic acid with all the monobasic acid or its glyceride, the polyhydric alcohol being present in not more than about 27 per cent excess, and then adding the remainder of the polyhydric alcohol and polybasic acid or a condensate thereof and reacting at a temperature lower than that of the first stage. When glycerides are substituted for the monobasic acids, their glycerol content is reckoned as part of the polyhydric alcohol. The first stage may be carried out at 200 to 300 DEG  C., and the second from 20 to 100 DEG  C. lower, and a catalyst, e.g. calcium resinate, may be present.  Reactants specified are: polyhydric alcohols--glycerol, glycol, polyglycerol, polyglycol, mannitol, erythritol, or mixtures thereof; polybasic acids--phthalic, adipic, succinic, maleic, citric acids, ether-dicarboxylic acids, the polycarboxylic acids of manilla copal, their anhydrides, or mixtures thereof; monobasic acids--fatty acids such as tallo<\>del or the acids of linseed, tung, or castor oils, resinic acids such as colophony, benzoic acid; glycerides--natural oils and fats such as castor, tung, linseed, olive, and fish oils.  The products are soluble in hydrocarbons, esters, ketones, and ethers, with or without alcohols.  There may be added to the solutions pigments, driers, and resins, to give paints and lacquers compatible with cellulose ester and chlorinated rubber lacquers.  The products may also be used in plastics, e.g. mastics and cements.
