Title: A process for the production of borohydrides
IPC: C01B6/00
Filed: 1957-12-24
Abstract: In preparing borohydrides, the hydride of Al, Mg, Ca, Sr, Ba, Li, Na, K, Rb, or Cs is reacted with a metaborate, or a metal oxideboron oxide mixture in 1:1 molar ratio of a metal of the above series, which is not further to the left in the series than the hydride metal, at above 100 DEG C. but below the melting point of the mixture, whereby the borohydride of the metal in the metaborate or in the oxide mixture, and the oxide of the hydride metal are formed. Alternatively, a metal aluminium hydride may be used in place of aluminium hydride, or the metal hydride may be produced in situ, e.g. from metal, or carbide, and hydrogen.  The hydride may be prepared as described in Specification 792,017.  By this method, Li, Na, Ca, Sr, or Ba borohydrides may be prepared from CaH2, and the initial reactants may be ground mixed, and briquetted. Air and moisture should be excluded from the reaction, and an acid anhydride, e.g. SiO2, may be added to take up the metal oxide formed.  The product may be extracted with water, with, or without, recrystallization from methanol, or with methanol, liquid ammonia, or isopropylamine.  In Examples:- (1), (2), NaBO2 or KBO2 is briquetted with CaH2 and heated in an autoclave under hydrogen pressure; (3) NaBO2 is briquetted with CaC2 and heated under H2 pressure; (4) NaBO2 is mixed with CaCl2 and Na sand and the mixture heated in an autoclave under H2 pressure.

Abstract: 951,118. Twisting yarns; stop motions; creels. T. M. M. (RESEARCH) Ltd. Nov. 17, 1961 [Nov. 22,1960], No. 40162/60. Headings DID and D1J. Each unit of a twisting machine comprises a package support positively rotated by a drive determining the rate of feed, a driven take-up means for twisting the yarn so fed, means for declutching and braking, or otherwise stopping, the package support, and a yarn-detector which when the yarn fails or slackens operates the means for stopping the package support and, if if desired, the take-up spindle. In the case of a double-sided ring frame for twisting yarns of glass fibre, a two-tier creel has a package 11 for each take-up spindle 12. The packages are driven by shafts 16 and the drive can be stopped by electromagnetic clutches 18 brakes 32 being also provided. The spindles have brakes 36. Between the creel and the take-up the yarn passes through vertically-spaced guide-eyes 20 which prevent the yarn vibrating and between which the thread detector is provided. In one form, Fig. 2, the detector comprises a rod 21 urged by a spring 24 towards engagement with a pivoted lever 26, but prevented by so moving by the tension of the yarn. When the yarn fails, the spring moves the rod to tilt lever 26 into contact with lever 28 to operate a microswitch 29 and energize solenoids 30, 31. The former controls the clutch and brake of the package spindles and the latter the brake of the take-up spindle. In Fig. 6 the detector comprises an arm 37 rotatably mounted on a shaft 38 and kept out of contact with a lever 40 by the yarn tension against the tension of a spring 39. When the yarn fails the arm 37 rotates to rotate the lever 40 to operate a microswitch 29. Normally, lever 40 is held by a spring 41 which also holds the lever in the position to which it is displaced by arm 37.

Abstract: 1493666 Hydrodynamic transmission control MOSKOV MASHINOSTROIT ZAVOD IM KALININA and MOSKOV AVTOMOBILNODOROZHNY INST 9 Oct 1975 41497/75 Heading F2W [Also in Division G3] An hydraulic cylinder 9 controls the displacement of a variable capacity pump 16 in a hydrodynamic transmission in accordance with a signal supplied to a torque motor 7 operating a flapper 13, the flapper regulating flow to the cylinder through a relay valve 21 and the position of the cylinder being fed back to the flapper through a cam 46, a member 48 and a spring 50. The difference in flow from nozzles 11, 12 controlled by the flapper is compensated for by movement of the cam 46 which alters the effective volumes of chambers 51, 52 communicating with the nozzles. The speed of movement of the cylinder is thus made dependent on the displacement of the flapper. When maximum pump output is reached, the pressure in the pump delivery line 53 displaces a cam 56 which through a spring-loaded pusher 60 and a lever 62 acts on the flapper 13 through a pre-set screw 69 to maintain power output constant. In a modification, an extension 41 of the cylinder 9 is engaged by spherical abutment surfaces on members (72, 73) Fig. 2 (not shown) which replace the member 46.

Title: A method of and apparatus for winding edgewise a thin metal strip
IPC: B21F3/00
Filed: 1960-12-02
Abstract: 944,252. Making laminated electromagnetic cores; coiling; punching; shearing. GENERAL ELECTRIC CO. Dec. 2, 1960 [Dec. 8, 1959 (4)], No. 41536/60. Headings B3A, B3E and B3W. A method of edgewise winding a thin metal strip comprises the steps of successively engaging the metal strip at spaced points, urging the strip in an arcuate path, and axially compressing the strip as it passes in the arcuate path to maintain the thickness of the strip substantially uniform as the strip achieves the arcuate form. A strip of core iron or silicon steel is notched along one edge in a punch press 4, is annealed in an oven 10 and passes to means 11 which coil it on edge on a mandrel 15. The coiling means 11 includes a slot 60, of a thickness slightly less than that of the strip to compress the same, in a winding shoe 64. The slot has an initial straight section 80, Fig. 7, and a subsequent arcuate section 81. The strip is pulled therethrough to coil it by pins 65 mounted to protrude through a rotatable member 62 and moved out to engage the strip and in to disengage it by fixed cams 66, 67 engaging the heads 72 of the pins. The strip is further engaged by an indented portion 83 on the shoe 64 to provide clearance for the strip as it is wound and also by a biasing roller 87 adjustable to determine the final form of the coil. Bolt holes are then punched in the coiled strip, while supported on splines 15<SP>1</SP> on the arbour 15, by punch means 12. The means 12 includes punch carriers 101, slidable on guide bars 100, on a rotated wheel 25 and moved by a cam slot 103 so that when in register with the coil of strip to be punched, the carrier 101 travels with the coil. A punch 113 is carried by a plate 114, mounted on rods 116 and is depressed, against springs 117 relative to the carrier 101, by engagement of a plate 115 on the plate 114 with a fixed roller 122 as the carrier passes thereunder. The strip on the arbour 15 is severed at intervals by a pair of rotated cutters 35, 36 having cooperating helical edges 145, Fig. 13. After the strip has been severed a stack 18 of coils is compressed axially by an hydraulically actuated clamp and welded along the length of the stack in an inert atmosphere by welding means carried by rotary table 17. The table 17 carries the stack 18 to a conveyer 19 which passes the stack through a stress-relieving oven 20.

Abstract: A polypeptide of molecular weight about 20,000 and having protease inhibitory properties, is prepared in a partially purified state from an aqueous suspension of powdered defatted peanuts by treating with acid at pH3-5 and/or alkali at pH 9-10, and removing the precipitate, treating the supernatant with an ion-exchange resin or by heating to 70-80 DEG  C. and removing the precipitate, dialysing the resulting solution, and then precipitating the partially purified product with a water-miscible organic liquid (e.g. ethanol).  This product may be purified to the homogeneous polypeptide by re-solution in water, precipitation with ammonium sulphate to 44% concentration, followed by re-solution, passage over diethylamino ethanol at pH5, and then at pH 7.5, and dialysis and lyophilization to give the purified polypeptide.  The product has anti-esterase and antiprotease activity against trypsin and chymotrypsin and also inhibits the fibrinolytic activity of plasmin; it has an electrophoretic mobility of 0.8 x 10-5 cms.2/sec./volt in pH 8.0 Michaelis buffer, an isoelectric point of pH 6.75, a sedimentation velocity of 0.82 Svedburg units, contains no tryptophan and a large amount of cysteine.  An amino acid analysis is given.ALSO:A protease inhibitor which is a homogenous polypeptide (see Div. C3) is prepared in a partially purified state by removal of unwanted proteins from an aqueous suspension of ground defatted peanuts, by (i) treating with acid at pH 3 to 5 and/or alkali at pH 9 to 10 and removing the precipitate; (2) treating the supernatant with an ion exchange resin or heating it to 70 DEG  to 80 DEG C, and removing the resulting precipitate; (3) dialysing the so-treated solution; (4) addition of a water-miscible organic liquid (e.g. ethanol) to precipitate the partially purified product.  This product may be purified to the polypeptide by dissolving it in water and re-precipitating by addition of saturated aqueous ammonium sulphate to a final concentration of 44%, followed by re-solution and passage over diethylaminoethyl-cellulose, first at pH 5, then again at pH 7.5, with final dialysis and lyophilisation of the solution emerging. Pharmaceutical compositions contain the purified polypeptide with a suitable carrier, and may be administered internally or externally as injectable preparations, solutions, tablets, drops, suppositories, powders, aerosols, pomades or callyria, a unit dosage preferably containing 200,000 to 2,000,000 inhibitory units (1 unit inhibits 1 S.T. unit of trypsin).  The polypeptide has inhibitory effects on the esterase and protease properties of trypsin, chymotrypsin and plasmin, and may be used to treat fibrinolytic conditions and pancreatitis.
