Abstract: 1,260,571. Extruding; forging. ALLMANNA SVENSKA ELEKTRISKA A.B. 9 June, 1969 [24 June, 1968], No. 29066/69. Headings B3H and B3P. An extrusion apparatus comprises a die 12 and a punch 1 formed with an outer part 4 and an inner part 3 which forces part of the billet 15 through the die and forms a hollow in the unextruded part which is mechanically interlocked to the part 3. The billet is limited for transverse spread in a sleeve 13 and the billet material flows into a groove 19 on the punch to form the interlock. The groove 19 may extend only partially around the inner part 3. The outer part 4 acts as a stripper during retraction of the punch. The die 12 has a set of openings (14), Fig. 5 (not shown), to form fins 18 which are thin and prevent the use of a conventional ejector.

Abstract: 1,215,002. Treating carbon fibres. COURTAULDS Ltd. 1 Feb., 1968 [2 Feb., 1967; 15 May, 1967; 23 June, 1967], Nos. 5105/67, 22537/67 and 29237/67. Heading C1A. [Also in Divisions B3, C7, F1 and H1] Carbon fibres are produced by carbonization of a filamentary material having a carbon-tocarbon backbone, such as viscose rayon, a polyamide or a polymer or copolymer of acrylonitrile. First the filamentary material is heated at 200-300‹ C. in an oxygen-containing atmosphere, then at 1000‹ C. or more in an inert atmosphere and finally at a higher temperature in an inert atmosphere to induce graphitization. The carbon fibres produced are oxidized, e.g. in concentrated nitric acid or in an aqueous solution of chromic acid, then are coated with metal to make possible their incorporation in carbon fibre-metal composite materials.

Abstract: 888,121. Fluid-pressure servomotor-control systems. BLACKBURN AIRCRAFT Ltd. Oct. 22, 1959 [Sept. 17, 1958], No. 29818/58. Class 135. An aircraft power flying control having two control surfaces for control axis and each control surface moved by two rigidly-connected jacks A, B in independent hydraulic systems has the servo valves E, F of the two jacks capable of excess movement and operatively associated at M so that each may travel normally simultaneously but non-movement of one valve allows excess movement of the other to control its jack and cut-off pressure to the jack of the inoperative valve so that this jack is stroked during movement of the operative jack. A pilot or auto-pilot simultaneously moves both valves within the limits prescribed by valve bobbins C1, C2, moving in end slots of valve interconnecting lever M, the valves also being connected via cranks E3, F3 and spring box O, so that pressure at P1, P2 passes via insolating valves G, J, passages D2, D6 and D8, D12 to the large sides of differential plungers A1 B1 to move to the right the connected cylinders A3, B3 connected to the control surfaces, or to exhaust the large sides via passages D7, R1 and D13, R2 so that pressure permanently applied to the small side of the plungers via passages D3, D9 moves the cylinders to the left. Movement of the cylinders produces a follow-up movement of the servo valve seats. Should the valve F stick, valve E is moved excessively to permit pressure to pass via P1, D10, D11 to act at K together with pressure via D110 acting on a land to shift the isolating valve J, close the connection between P2 and D8 and actuate a warning switch Q2. Cylinder A3 moves under the control of valve E and strokes cylinder B3 in virtue of a by-pass containing check valve NR2 across the ends of the cylinder. Should pressure at P2 fail, spring L2 moves, isolating valve J to cut-off pressure and operate indicator Q2. Corresponding action occurs if pressure at P1 or valve E fails.

Patent GB-837302-A (GB)
Title: Recovery of bacitracin from aqueous solutions
Filed: 1956-10-03
Abstract: Bacitracin is recovered from an aqueous solution, especially a fermentation broth containing 3% proteinaceous solids, by contacting the liquid with a synthetic organic cation exchange resin operating on the hydrogen cycle, the resin having a cross-linkage of not more than 2% and eluting the adsorbed bacitracin from said resin with a base especially a weak base such as aqueous ammonia.  The resins are styrene-divinyl benzene resins with a low cross linkage of 1 or 2% and having sulphonic acid functional groups, e.g.  Duolite C-25 and Dowex 50-XL, but carboxylic type cation exchange resins e.g. "Amberlite" XE-89 (Registered Trade Mark) may be used.  A filtered broth is adjusted to pH 4.0 and passed down a column of the resin, which is washed with water and eluted with 1N. aqueous ammonia.  The rich eluate cut is concentrated under vacuum at not over 50 DEG  C. until the pH is less than 9.0 e.g. pH 8.7 and is then passed through a weakly basic anion exchange resin such as Duolite A-7 on the acetate cycle and and having primary, secondary and tertiary amines. The effluent is further purified by treatment with aqueous aluminium sulphate and filter aid, any precipitate formed being removed. Zinc bacitracin is produced by adjusting the pH to 4.4, adding zinc chloride and readjusting the pH to 7.5.  Reference has been directed by the Comptroller to Specification 782,999.

Within the shaft 13 is a rod 15 having a hollow portion 17 to which the honing element is secured by a hollow screw 21 passing through the base 53 of the body of the element. A driving pin 73 carried by the portion 17 engages a radial slot 71 in the base 53. A torque pin 25 extends through the portion 17 into slots 27 in the drive shaft 13. During honing, the rod 15 is advanced axially toward the workpiece 29 to compensate for wear of the element and to maintain constant pressure. Coolant is admitted through inlet ports 31 in the drive shaft 13 and passes through ports 33 in the portion 17 to the interior thereof and through the hollow screw 21 into the honing element. Pressure is relieved by ports 35 in the honing element. A shield 37 carried by the drive shaft 13 surrounds the honing element to prevent random spraying of coolant out of ports 35. The workpiece 29 may be a stud having a part-spherical head and a shank by which it is rotated during honing.
