Abstract: A plastic modelling composition comprises a mixture of at least partly gelatinized grain flour, water, a non toxic water soluble salt such as sodium chloride and a substantially odourless hydrocarbon distillate such as kerosene but does not include the presence together of a drying agent and a hardening and astringent agent. The mixture may include a drying agent such as borax, salicylic acid, sodium, benzoate sorbic acid, sodium or calcium propionate, acetic or methane carboxylic acid, glacial acetic acid or vinegar or mixtures thereof, or a hardening and astringent agent such as the alums.  Any grain flour may be used but wheat or rye flour is preferred. The water soluble salt which acts as an extender may be sodium chloride, sodium hypochlorite or sodium chlorite.  A non toxic dye and a perfume may also be incorporated and the mixture is heated to at least 160 DEG F. to gelatinize the flour. The preferred composition range by weight is:- .Flour.30-57% .Water.30-57% .Salt.1-25% .Hydrocarbon. 1/2 - 5% .Drying agent.0.3-15% .or hardening agent.0.4-4%

Title: Aluminosilicate catalyst
IPC: B01J29/08
Filed: 1963-05-08
Abstract: A crystalline aluminosilicate has a silica/alumina ratio in excess of 3 and has uniform pores between 6 and 15 <\>rA in diameter, the cation of the aluminosilicate being a metal below sodium in the electromotive series (as defined in the Handbook of Chemistry and Physics, 43rd edition, published by the Chemical Rubber Publishing Company) or calcium, an organic nitrogen base or a mixture thereof with each other or with hydrogen and/or ammonium, the alkali metal content of the aluminosilicate being less than 3% by weight.  The aluminosilicate is prepared from preferably a Y zeolite by base exchange with solutions containing the appropriate cations, particularly calcium, magnesium, rare earth metal, rare earth metal plus hydrogen or manganese ions, to replace at least 70% of alkali metal ions of the zeolite. The aluminosilicate may be used as a cracking catalyst, preferably dispersed in a proportion of 1 to 90% by weight in a matrix of a binding agent, the composition optionally containing an additive to increase its porosity.  The binding agent may be an inorganic oxide gel, e.g. alumina, silica, zirconia, hafnia, thoria, titania or mixtures of these, particularly co-gels containing at least 55% silica with at least one of the others or beryllia, or it may be an activated metal powder, e.g. aluminum or iron-containing alloys, a clay, e.g. montmorillonite or kaolinite, charcoal, graphite, mullite, kieselguhr, activated carbon, bauxite or activated carbon.  Mixture of aluminosilicate and binder may be achieved by ball-milling, preferably under water, or the aluminosilicate may be dispersed in finely divided form, i.e. less than 40 microns, in a hydrosol or hydrogel, or it may be added to one of the reactants used in forming the hydrosol, or it may be mixed with the reactants in e.g. a mixing nozzle.  The hydrogel is broken up into beads by extrusion, casting or pelleting, or the hydrosol may be introduced into oil wherein the globules set to a hydrogel in the form of microspheres of 20-300 microns which pass to an underlying aqueous layer and are removed. Base exchange of the starting zeolite may take place before or after mixing with the binder. In the former case, a subsequent base exchange may be required to remove alkali metal derived from the binder.  The porosity-imparting additive, up to 40% by weight of the composition, and of particle size 1-40 microns, may be clay, alumina, zircon, barytes, carbon, wood flour, silica, magnesia, recycle catalyst fines or spent catalyst fines.  In subsequent preparative treatment, or during use, combustible additives such as carbon or wood flour may be removed.

Filed: 1932-06-29
Abstract: 406,999. Arc-rupturing in switches. MARX, E., 3, Rankestrasse, Brunswick, Germany. June 29, 1932, No. 18401. Convention date, June 29, 1931. [Class 38 (v).] In an arrangement of the kind described in Specification 406,003 for converting or interrupting high voltages, each electrode B, C is formed with a passage way serving as a vent for the products of arcing, a blast of fluid is directed from the periphery over the surface of the electrodes, and a magnetic field moves the arc roots relatively to the electrodes, thus imparting to the discharge a rapid wandering movement which prevents the surface of the electrodes from being burnt. The control windings A are fed by the current passing through the arc, or from a separate insulated source the strength being regulated by a variable resistance. Iron cores E, Fig. 2, may also be arranged to give a staggered field which induces the arc to enter the nozzle D, where it is extinguished. The coil A may be wound toroidally over a non- magnetic ring. According to the Specification as open to inspection under Sect. 91, the arc may be extinguished by expanding a vapour ; the windings A may be immersed in cooling-fluid; and the electrodes or magnets may be rotated. This subject-matter does not appear in the Specification as accepted.

Title: Purification of amylase preparations and production of dextrose
IPC: C12N9/30
Filed: 1958-06-11
Abstract: Transglucosidase is removed from fungal amylase preparations (i.e. starch hydrolysing enzyme preparations obtained by growth of fungi imperfecti on a medium) by treating the said preparation in an aqueous medium at a pH in the range 3.5 to 4.5 with a clay mineral and separating the liquid medium containing the purified enzyme from the clay mineral.  The enzyme preparation may be the whole or clarified broth of a species of Aspergillus, e.g. A. niger NRRL337 or NRRL330 and A. flavus-oryzae, a suspension of dried or partially dried enzyme preparation containing water-insoluble constituents, or a solution of a completely soluble enzyme preparation.  A suspension is preferably clarified before treatment with the clay. 0.5 to 5.0 grms of clay per 100 mls of enzyme solution is used and the pH of treatment is 3.5 to 4.5.  The clays are natural silicates of alumina and in general are montmorillonites, actapulgites, Kaolinites and Illites.  The purified enzyme when used in the production of dextrose from starch gives high yields (93%-94%, dry basis of dextrose) (see Group VI).ALSO:Dextrose in high yield (93-94%, dry basis) is produced by hydrolysing starch which has been subjected to a preliminary hydrolysis, e.g. with an acid, by means of a fungal amylase preparation from which transglucosidase activity has been removed by treatment with a mineral clay (see Group IV (b)).
