Abstract: 494,653. Transmitting mechanical power; electricity supply. BRITISH THOMSON-HOUSTON CO., Ltd. April 13, 1938, No. 11403. Convention date, April 16, 1937. [Class 38 (iv)] Equalizing load.-In a system of vehicle propulsion in which an engine drives one or more generators supplying an auxiliary electrical load in addition to the main propelling motors, the engine is relieved of the auxiliary load so that all the power available may be utilized by the propelling motors when the control lever for the engine is moved to the full power position. The engine 10 drives a main generator 12 supplying the propelling motors 16, 17 and an auxiliary generator 13 which supplies its field 22, the field 19 of the main generator, the battery 21 and an auxiliary load such as the blower 24, all being arranged in parallel. When the engine throttle valve is opened fully by its lever 11, contactor 26 is opened so that battery 21 and blower 24 are no longer supplied by the auxiliary generator, the blower being then driven by the battery. A reverse current relay 30 prevents discharge of the battery 21 through the auxiliary generator 13 if the generator voltage falls below that of the battery. In a modification, the main generator field 19 is also supplied by the battery 21 at maximum load. In a further modification, the auxiliary generator may be supplied from the battery and function as a motor with maximum load conditions. The auxiliary generator may be dispensed with, the battery and the blower 24 being cut out at maximum load from the supply circuit of the main generator.

Title: Improvements in or relating to the manufacture of sugar esters
IPC: C11C3/00
Filed: 1941-09-20
Abstract: 552,161. Sugar esters. BRITISH CELANESE, Ltd. Sept. 20, 1941, No. 12194. Convention date, Jan 15. [Classes 2 (ii), 2 (iii) and 15 (ii)] Sugar esters, in pure condition, are obtained by treating a sugar with an anhydride of a fatty acid containing not more than six carbon atoms, in the presence of an esterification catalyst, removing part of the reaction mixture by distillation and precipitating the ester by adding a dilute aqueous alkali. In an example sucrose is added to a mixture of acetic anhydride and sodium acetate which has been heated. After stirring, the product is heated to complete the acetylation and the excess acid removed by heating under reduced pressure. The product is poured into dilute caustic soda, and the ester separates as a solid on standing. Acetates, propionates and butyrates of sugars such as glucose, lactose, maltose and xylose may be obtained. The esters may be used as detergents either alone or with soaps, or as pigments or effect materials in paints and plastics. They may also be used in fibres, films or filaments made of cellulose acetate or other organic derivative of cellulose. When such fibres containing the sugar esters are subjected to a delustring treatment a voluminous matt effect is produced. Films or foils made of organic cellulose derivatives containing the sugar esters may also be used in the manufacture of laminated glass, fabric or other sheet material.

Title: Preparation of active contact masses from kaolin clays
IPC: B01J21/16
Filed: 1956-04-24
Abstract: A sulphated clay, preferably a sulphated kaolin clay, is treated to decompose the sulphate and steamed at elevated temperature to produce a catalyst.  Preferably the clay sulphate is decomposed under reducing conditions but strictly thermal decomposition can be used at higher temperatures, e.g. about 1500 DEG  F.  The decomposition of the sulphate may be effected in the presence of steam or the desulphated clay may be subsequently subjected to steam treatment. However, even when desulphation is effected in presence of steam, a subsequent steaming step with or without an inert gas present, is beneficial.  Details are also given of the sulphation step including ageing treatments when the clay is cast into the form of pellets prior to the desulphation step.  A supplementary treatment with ammonium chloride as a vapour or in solution, or sulphiding gases to remove high iron contents from treated clays is also described.  The contact masses are particularly useful as catalysts in cracking petroleum oils.
