Title: Improvements in and relating to the production of beryllium alloys
IPC: C22C1/02
Filed: 1934-02-14
Abstract: Beryllium alloys are produced by causing beryllium oxide to react with carbon, either in vacuo or in an atmosphere consisting mainly of hydrogen, in contact with a molten bath of the metal or metals to be alloyed with beryllium.  When metals are used in which carbon is soluble, the carbon may previously be dissolved in the bath; an excess of carbon remaining may be eliminated by treating the product with a further amount of beryllium oxide or with another oxide such as magnesia.  The carbon may be dissolved in the bath in the form of beryllium carbide or calcium or other carbide.  Alloys with one or more of the following metals, iron, nickel, cobalt, manganese, chromium, molybdenum, tungsten, uranium, copper, are mentioned.  The hearth or furnace lining may itself be made of beryllium oxide and the metal with carbon or in the form of carbide introduced therein or in the case of copper, in which carbon is not soluble, the copper is melted in a carbon crucible and beryllium oxide with or without calcium carbide added.

IPC: C07H13/12
Filed: 1961-02-10
Abstract: <PICT:0977327/C1/1> The antibiotic Moenomycin is prepared by cultivating an antibiotic Moenomycin-producing strain of Steptomyces bambergiensis, Streptomyces ghanaersis, Strepromyces ederensis or Streptomyces geysiniensis under aerobic preferably submerged conditions in an aqueous nutrient medium containing a source of carbon and of nitrogen with or without an inorganic salt until a substantial antibiotic activity is imparted to the medium and isolating the antibiotic Moenomycin from the medium. The antibiotic is isolated from the culture solution by extraction with an organic solvent e.g. butanol at pH 2-3 or by means of an adsolvent and from the mycelium by extraction with a water-miscible or partially miscible organic solvent e.g. methanol, acetone or dioxan, or by destruction of the cells by deep freezing or thawing, or by homogenizing, with water or aqueous solutions of salts, or organic or inorganic acids. The evaporated solvent extracts are extracted with hot polar organic solvents and the antibiotic is precipitated from the concentrated extract by a non-polar organic solvent e.g. diethylether or ethylacetate. The antibiotic can also be isolated from the mycelium extract by (a) precipitation from the aqueous residue remaining after evaporation of organic solvent, with mineral acid at pH 1-5, (b) extraction of the acidified aqueous residue with a solvent which is non-miscible or only partially miscible with water and (c) adsorbing the aqueous residue on bleaching earths and eluting with aqueous organic solvents. The antibiotic is purified by adsorption method (c) and counter current distribution in a butanol/water system. The antibiotic Moenomycin is a weak acid and forms metal salts with alkali metal (e.g. sodium) hydroxides and has negative ninhydrin, biuret, fehling, Ehrlich, Sakaguchi, aniline phthalate and ferric chloride reactions. The antibiotic Moenomycin is colourless; has the elemental analysis C=50.4%, H=7.3%, N=6.3%; I.R maxima at 3.02, 3.45, 6.03, 6.50, 7.28, 7.55, 8.20 and 9.38 m  as shown in Figure; decomposes at 200 DEG C.; in paper electrophoresis shows no migration in buffer solutions of pH 1.9 to 7.8 and anodic migration in buffer solution at pH 7.8; solubility in water, alcohols of 1 to 4 carbon atoms and polar solvents e.g. pyridine and sparing solubility in alcohols of more than 4 carbon atoms and insolubility in diethylether, and other non-polar solvents; stability in neutral aqueous and methanolic solutions and instability in acid and alkaline solutions; and no U.V. absorption maxima in the range 220-400 mm Various Rf values are given.

Abstract: 539,800. Variable-speed gearing. LANCASHIRE DYNAMO & CRYPTO, Ltd., and WILSON, E. P. March 20, 1940, No. 5184. [Class 80 (ii)] In variable-speed gearing in which gears 7, 8, 9, loose on a driven shaft mesh with gears on a countershaft and are adapted to be clutched in succession to the driven shaft, the clutch members 15, 16, are moved in unison by a bell-crank lever 20 or the like so that one of the gears is disengaged shortly before one of the others is engaged. The countershaft (not shown) carries gear wheels permanently in mesh with gears 7, 8, 9 loose on the driven shaft 10 and is rotated by an electric motor or other means. The gear 8 is secured to a bevel wheel 11 which may be geared to a second driven shaft. The clutch member 15 has dogs 12a, 14a, engageable with dogs on the gears 7, 9, respectively and the clutch member 16 has dogs 13a engageable with dogs on the bevel wheel 11. Pins 21 on the bell-crank 20 engage slots 22 in clutch actuating forks 17, 18, which are guided on a rod 19. In the position of the bell crank shown in Fig. 2, the dogs 13, 13a, are in engagement and give a medium gear ratio. Movement of the bell crank 20 about its pivot 23 will disengage dogs 13 13a, and engage either dogs 12, 12a, or 14, 14a, to give a low gear or high gear respectively, a neutral position being passed through in going from one gear to another. The pivot 23 may be connected directly to an operating handle. In the construction shown, a preselector gear is provided. The pin 23 is connected to a crank 28 with crank pin 27. An operating handle 37 pivoting on a pin 31 carries a crank pin 29.

IPC: B60T13/66
Filed: 1965-02-05
Abstract: 1,085,081. Fluid pressure brakes. KNORRBREMSE G.m.b.H. Feb. 5, 1965. No. 5225/65. Heading F2F. An electropneumatic compressed-air brake for rail vehicles, comprising a purely pneumatic control device, which includes a triple pressure control valve 5, and an electropneumatic control device 19 connected in parallel through a double check valve 25 with a brake cylinder 27, is characterized in that a shut-off valve 23 is arranged between the constant pressure chamber of the triple valve and an auxiliary reservoir 11 such that the said shut-off valve is opened only during electropneumatic brake operation to allow compressed air to pass to the brake cylinder from the constant pressure chamber in addition to that air drawn from the reservoir. On purely pneumatic brake operation, triple valve 5 connects lines 13 and 24 and compressed air is delivered from the reservoir through valve 25 to the brake cylinder. Solenoid-actuated valves 15 and 17 of the control device 19 are in a de-energized condition and respectively prevent communication between lines 13 and 26 and vent the chamber on the right-hand side of piston 41 in valve 23 to atmosphere through 21 so that valve member 37 remains seated. On electropneumatic brake application, train wires 33, 29 and hence valves 15 and 17 are energized. Compressed air flows from the reservoir through inter-connected lines 13 and 26, and valve 25 to the brake cylinder. Simultaneously, the pressure in line 26 moves piston 41 against spring 43 to unseat member 37 so that the control chamber pressure falls to the same extent as the auxiliary reservoir pressure which has fallen below that pressure in train pipe 1 thereby ensuring triple valve 5 is maintained in the release condition. Sufficient pressure is retained in the reservoir and constant pressure chamber to actuate the brake cylinder in the event of electropneumatic device failure. In the embodiment of Fig. 2, the shutoff valve is a solenoid-operated valve which is energized to open from train wire 33.
