Title: A process for the production of a fermentation beverage
Filed: 1952-07-04
Abstract: In the production of fermentation beverages which may be alcoholic, non-alcoholic or of low alcohol content, e.g. not greater than 5 per cent, in which sugar-containing solutions, e.g. cane or beet sugar, hydrolyzed starch solution, wood sugar solutions, sugar-containing extracts of vegetable or animal origin such as for example carrot extracts, honey, enzymatic and acid hydrolyzed degradation products of starch- or inulin-containing natural products, such as various types of grain, de-bittered horsechestnuts, acorns, Helianthus tuberosus and chicory and by-products of wood-starch, sugar production, e.g. beet and cane sugar molasses, are fermented with Endomyces-types selected from the group comprising Endomyces Magnusii, Endomycopsis and Sachsia suaveolens in the presence of aromatic vegetable materials for example leaves of the cupuliferae or rosaceae, hazel nut tree, oak, beech, wild briar, strawberry, raspberry, blackberry.  A second fermentation may be carried out with a wine-yeast for example Bordeaux-, Laurero-, Tokay-yeast and may also be effected under the pressure of the CO2 developed during fermentation and either in a closed tank or in a bottle whereby champagne-like products can be obtained.  After fermentation sweetening may be effected preferably with saccharin. In an example 0.5 kg. of a mixture of disintegrated dried leaves consisting of 1 part beech leaves, 2 parts dogrose leaves, and 2 parts blackberry leaves are mashed with cold water and allowed to stand for one hour after when 5 kg. of sugar together with 3/4 of a hectoliter of water are added and the mixed thoroughly stirred, after which a 100 g. of damp Endomyces Magnusii are added, the volume being made up to 1 hectoliter the charge then left to ferment for eight days under a pressure of about three atmospheres whereupon

Filed: 1964-04-24
Abstract: 1,005,324. Diffusion pump baffles. MAXPLANCK-GES ZUR FORDERUNG DER WISSENSCHAFTEN e V. April 24, 1964 [April 26, 1963], No. 17211/64. Heading F1E. [Also in Divisions F2 and F4] In a device for controlling the temperature of a low-temperature baffle 3, Fig. 1, the supply of a condensed gas refrigerant is controlled by a valve 38 responsive to the temperature of a baffle condensation surface 36, the rate of flow of the refrigerant being controlled by a valve 32 located in a gas outlet. The diffusion pump 1 is surmounted by a water-cooled baffle 2 and a baffle 3, the latter being supplied with refrigerant gas, e.g. nitrogen from storage vessel 5 through pipes 41 and 301, Fig. 3, the joint of which has interengaging vacuum jackets 42 and 302 enclosed by rubber sleeve 43. Temperature sensor 35, soldered to baffle surface 36, communicates with bellows 33, which closes gas venting pipe 6 and operates microswitch 39 to close the circuit of a heating element 7. In operation, the filling, e.g. n-butane, n-pentane, propane, ethylene, ethylene-methane, methane or oxygen, in sensor 35 and bellows 33 is at first in the vapour state, the bellows being expanded and valve 37, 38 being closed to seal pipe 6, switch 39 is closed and the liquid refrigerant in vessel 5 is heated by heater 7. The pressure above the liquid rises forcing refrigerant through siphon 4 into baffle 3. At the desired temperature of baffle 3, the filling gas condenses and the bellows contracts to allow valve 37, 38 to open gas venting pipe 6. The pressure build up in the storage vessel 5 collapses and the refrigerant flow ceases. The baffles 3 may be connected in series so that the temperature of exhaust gas passing to atmosphere is controlled substantially to room temperature.

Abstract: 515,129. Tyre treads and other non-slip surfaces. DUNLOP RUBBER CO., Ltd., and WILSON, J. A. June 11, 1938, No. 17371. [Class 144 (ii)] [Also in Groups V and X] A non-slip surface for tyre treads and other purposes is produced. as follows. A composite strip is first formed by superpusing a layer 2 of fast-vulcanizing rubber mix on a layer 1 of relatively slow mix and vulcanized to cure the layer 2 and only partially cure the layer 1. The composite strip is then superposed on a base 3, also of slow-vulcanizable mix, and the exposed surface of the layer 2 chemically treated, as by hydrochloric, nitric, or sulphuric acid, chlorine, or other halogen element or oxides of nitrogen, to render this surface of weakened adhesion to rubber. After forming perforations 5 through the layers, 2, 1, the strip is cut into blocks 6. The latter are then turned over into the positions shown in Fig. 3, assembled to form a continuous length and vulcanized under pressure to produce the finished material, shown in Fig. 4, having zones of weakened adhesion which, when the material is stretched in use, result in the formation of slits 10, Fig. 5, at the wearing surface.

Title: Process for reforming hydrocarbons
IPC: B01J23/96
Filed: 1956-06-07
Abstract: In reforming naphthas having a sulphur content below 0.06 per cent by weight over a noble metal catalyst at not less than 910 DEG  F. and 100-500 p.s.i.g. in the presence of a hydrogen-containing gas to improve the octane number to at least 95 Research clear, the reaction temperature is increased as the catalyst loses activity to maintain the conversion relatively constant until a temperature of 960-975 DEG F. is necessary when the catalyst is purged with a hydrogencontaining gas, the pressure reduced, hydrogen purged with an inert gas, the catalyst regenerated with a gas containing 0.5 to 3 mol. per cent of oxygen followed by a gas containing more than 4 mol. per cent of oxygen and the <PICT:0815339/IV (b)/1> abovementioned steps repeated. In a preferred embodiment naphtha feed is passed through the hydrofining desulphurizing unit 13 preferably to reduce the sulphur content below 0.002 per cent and mixed with recycle gas containing 50-95 mol. per cent of hydrogen from line 15 in an amount of 2000-8000 S.C.F. of hydrogen per barrel of feed.  The feed is further preheated in furnace 23 to the desired reaction temperature and is then passed through a bed of catalyst in reactor A.  The catalyst may be platinum or palladium on alumina.  The effluent leaves the reactor at a lower temperature and the reactants passing through line 31 are reheated in furnace 35 before passing through reactor B and again heated in furnace 47 and passed through reactor C.  The products pass by lines 55 and 59 to separator 69 after cooling.  Liquid product leaves by line 71 and recycle gases by line 73.  A tail gas may be removed by line 81 and recycle gas passed by line 79, being dried if desired by passage through a bauxite drier 89 and line 15. When a preheat temperature of 960-975 DEG  F. becomes necessary the catalyst requires regeneration.  The feed is cut off but recycle gas flow continued to purge the system; the recycle gas is then purged by means of steam ejector 101 and inert gas produced in the generator 105 in which natural gas or heavy hydrocarbon oil is burned.  When the hydrogen is purged the pressure of flue gas is allowed to build up and air is drawn in through intake 121 until the circulating gas contains 0.5 to 3 mol. per cent of oxygen, and regulated so that the temperature in the reaction beds does not exceed 1075 DEG  F., heat being supplied when necessary by heater 145. By suitable manipulation of valves gases can be passed through reactor A only or also reactor B and/or reactor C.  When free oxygen emerges from the reactors regeneration is complete. Rejuvenation is effected with a gas containing 5-20 mol. per cent of oxygen, preferably air. Temperatures of 750-1100 DEG  F. are used for about four hours, longer periods being necessary with gases containing less oxygen.  In an alternative arrangement the reactors are connected so that oxygen-containing gas can be passed through the reactors individually, sequentially or in parallel.

Abstract: 869,773. Preparing oximes from nitro-cyclo alkanes, electrolytically. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 8,1960 [May 25, 1959], No. 17719/59. Drawings to Specification. Class 41. Nitro cyclo-alkanes are converted to oxirnes by cathodic reduction to form the hydroxylamine in the catholyte which is then circulated to the anode compartment of the same or another cell to form the oxime by oxidation. As the hydrogen requirement is twice that of the oxygen requirement, the anode compartment is divided with an electrode in each, the catholyte being then circulated through one in a continuous process. An apparatus is described comprising three cells each having a porous cylindrical pot surrounded by a cylindrical lead anode and a nickel rod cathode at the centre. The cells communicate in series through overflow pipes whereby the catholyte flows from cell A through cathode compartments of cells B and C and then into the anode compartment of cell A and then into those of cells B and C to a reservoir. In an example, a solution of nitrocyclohexane in ethanol containing a little H 2 So 4  flows through the cells at 17 to 25 C., and at an anode C.D. half that of the cathode. A little acid is added at intervals. The product is recovered by neutralizing, and distilling off the alcohol. German Specification 964,773 is referred to.
