Abstract: 1359403 Creatinine amidohydrolase and creatine amidinohydrolase. BOEHRINGER MANNHEIM GmbH 4 May 1972 [5 May 1971 (2)] 20767/72 Heading C3H Creatinine amidohydrolase (and creatine amidinohydrolase) may be obtained from micro-organisms, such as the designated strains Alcaligenes sp. WS 51400 and Penicillium WS 90001, which have been cultured in a creatininecontaining medium, by digesting them using high pressure, ultrasonics or a disintegration mill, and recovering creatinine amidohydrolase in purified form from the water-soluble digestion fraction by known methods carried out at a pH above 7À0. The water-soluble digest fraction can be purified by fractionation with polyethyleneimine at a buffer concentration of about 0À1 M and /or by precipitation with 90% isopropanol. Separation of the two enzymes is achieved by adsorption on a weakly basic ion exchanger (specified) at an ion concentration below 0À1 M in a column or batchwise. The exchanger is then washed with 0À1 M buffer to remove non-active proteins, and creatinine amidohydrolase and creatine amidinohydrolase are eluted with an ion concentration of 0À2 M and 0À5 M, respectively. Alternatively, the enzymes may be isolated from solution by salt precipitation of fractionation, e.g. with the use of ammonium sulphate, at a concentration of 2À2 M for creatinine amidohydrolase and 2À7 M for creatine amidohydrolase or the mixture of the two enzymes.

Abstract: 424,676. Fluidpressure brakes. KEBRT, J., 4, PalackÚho nßm., Olomouc, Czecho-Slovakia. July 17, 1934, No. 20949. Convention date, July 17, 1933. [Class 103 (i)] In a hydraulic brake system of the kind comprising coaxially arranged high and low pressure master cylinders and a relief valve by which liquid is transferred to the reservoir from the low pressure cylinder, at the completion of the low pressure stage a restricted passage or other hydraulic resistance is arranged in front of the valve to prevent or retard premature opening of the valve. When the low and high pressure pistons 1, 4 are pressed downwardly by the lever 8, liquid is at first delivered from the cylinder 2 through openings 11 and also past a non-return valve 12, to the pipe line 14 as well as from the smaller cylinder 3. When the openings 11 are closed by the piston 4, the brake shoes are in contact with the drum and with continued movement of the pistons liquid is delivered from the cylinder 2 past the valve 17 until the pressure reaches a value sufficient to lift a spring-loaded valve 20, Fig. 3, by which liquid is then delivered to the reservoir 19, the piston 4 alone being then operative. The valve 20 is contained in a non-return valve 26 supported by a spring 27 and which permits a return flow from the reservoir to the cylinder 2 during the release movement of the pistons. The passage in the valve 26 leading to the valve 20 comprises a calibrated bore 22 which offers resistance to the flow of liquid such as to prevent or minimize opening of the valve 20 arising from a premature rise of pressure in the cylinders due to rapid movement of the pistons.

Abstract: 188,395. Roux, M. Aug. 9, 1921. Gas meters.-In dry gas meters having three measuring chambers 19, 20, 21 formed by the casing 1 of the meter and two metallic bellows 15, 16, the bellows are so arranged that the internal stresses therein are equalized by transmitting the tensions of one bellows to the other as said bellows are alternately expanded and contracted. The bellows 15, 16 are connected by links 13, 14 provided with slots adapted to be engaged by rollers 9, 10 on two cranks 7, 8 on the usual distributing valve shaft 6. The cranks 7, 8 are set at about 90‹ to one another, so that if the bellows 15 is in its inflat d condition while the bellows 16 is in its mid-position and gas is admitted to the meter and the crank-shaft 6 rotated about 90‹, the bellows 15 in returning to its mid-position or state of rest presses the bellows 16 together. In rotating the shaft further about 90‹ the bellows 15 is pressed together by the stresses in the bellows 16 returning to its state of rest. By the next movement of the shaft of about 90‹ the stresses in the metal of the bellows 15 are used to bring the bellows 16 into its inflated position, and after a further rotation of about 90‹ of the shaft the inflated bellows 16 returns to its state of rest wherebv the stresses in the metal cause the bellows 15 to assume its inflated position. Each bellows consists of a series of ring-shaped metallic diaphragms with flanges on the inner and outer edges, the flanges of two adjoining diaphragms being connected to one another by soldering, cold rolling or folding.

Title: Process for the hydrogenation of aliphatic mono- and dicarboxylic acids
IPC: B01J23/80
Filed: 1956-07-09
Abstract: A catalyst for the hydrogenation of aliphatic mono- and di-carboxylic acids and esters thereof comprises a Zn-Cu-Al alloy surface-etched with caustic alkali, the Zn content being 5-40 per cent and the Al and Cu contents each 30-60 per cent.  The preferred composition is Zn20, Cu40, Al40.  The catalyst is made by melting the constituents together in an inert atmosphere, grinding to any desired size from lumps to powder, and heating to 50-100 DEG  C. with caustic soda or caustic potash solution for 10-120 minutes.  The activated catalyst is then washed with water and another solvent (e.g. methanol) and dried away from air.  The catalyst becomes inactive in use and can be regenerated 10-20 times by the same process as above.  Examples are given of the preparation of typical catalysts.ALSO:Aliphatic mono- and di-hydric alcohols are made by hydrogenating saturated monocarboxylic acids of 2-18 carbon atoms or dicarboxylic acids of 2-12 carbon atoms, or esters thereof, at 180-350 DEG  C. and 100-500 atmos. in the presence of a Zn-Cu-Al alloy surfaceetched with caustic alkali; the Zn content of the alloy is 5-40 per cent and the Al and Cu contents are each 30-60 per cent, the preferred composition being Zn 20, Cu 40, Al 40.  The process may be intermittent or continuous, the latter employing the catalyst in lump form.  The preheated acid or ester is dissolved in e.g. methanol, passed with hydrogen over the heated catalyst, and the gaseous products separated and recycled. If the catalyst is in powder form it is separated by filtration or centrifuging before the product solidifies.  When the catalyst becomes inactive it can be re-etched with caustic alkali.  The products may be converted into the corresponding chlorinated hydrocarbons.  Examples show the hydrogenation of (1) dimethyl adipate to hexanol-1 and hexanediol-1 : 6; (2) adipic acid to hexanediol-1 : 6; (3) sebacic acid to decanol-1 and decanediol; (4) dimethyl pimelate to heptanediol-1 : 7; (5) dimethyl succinate to butanediol-1 : 4; (6) methyl stearate to stearyl alcohol and octadecane; (7) beef tallow to a fatty alcohol mixture.
