Abstract: 1,256,813. The antibiotics largomycin FI, FII and FIII. TANABE SEIYAKU CO. Ltd. 17 Feb., 1970 [19 Feb., 1969], No. 7468/70. Heading C2A. The novel antibiotics largomycin FI, FII and FIII which are characterized as follows: and which all have indefinite melting points and yield after acid hydrolysis, glucose and the amino acids lysine, arginine, histidine, aspartic acid, glutamic acid, threonine, serine, proline, glycine, alanine, valine, leucine, isoleucine, tryptophan, tyrosine, phenylalanine and methionine, are prepared by cultivating Streptomyces pluricolorescens NRRL 3679 or a largomycinproducing mutant or variant thereof aerobically in aqueous nutrient medium at 25 to 35 C. and recovering the largomycins from the fermented medium. The antibiotics are recovered by removing the mycelium from the medium, and saturating the resulting aqueous phase with ammonium sulphate to precipitate a crude mixture of largomycins FI, FII and FIII. These may be separated from each other by fractionation of their aqueous solution with progressive concentrations of ammonium sulphate, or fractional elution with pH 7À0 phosphate buffer from a dextran gel column; they are then purified by dialysing out the dialysable impurities and the pure solution is freeze dried. Complete separation of the three antibiotics may be made by preparative electrophoresis on a polyacrylamide gel column. Largomycins FII and Fm may also be separated from each other by extracting the solid mixture with pH 4À0 acetic acid-sodium acetate buffer containing ammonium sulphate, which dissolves out the FIII Pharmaceutical compositions having antimicrobial and anti-tumour activity comprise one or more of the antibiotics largomycin FI, FII and FIII together with a pharmaceutically acceptable carrier. The antibiotics may also be included in animal feedstuffs or additives for animal feedstuffs.

Abstract: 1,257,349. Coatings. TRW Inc. 20 March, 1969 [21 March, 1968], No. 14770/69. Heading B2E. Coatings are applied to a substrate by immersing the substrate in a liquid suspension containing matrix material in particle form and a multiplicity of fibres of material different from that of the matrix, aligning the fibres in the liquid suspension and while moving the substrate through the liquid suspension depositing the fibres commingled with the matrix material as a film half to 30 microns thick with the fibres oriented parallel to each other and to the plane of the layer. The fibres may be suspended in a non-volatile liquid such as amyl acetate and an alternating electrical voltage applied to the liquid to align the fibres. The substrate may then be drawn upwardly through the fibres to the surface. The matrix material may be particles or powders of material such as aluminium, nickel, titanium, coloumbium, tantalum or alloys of these. The fibres are preferably single crystal fibres of silicon carbide, aluminium oxide or silicon nitride, or of glass. The substrate may be a thin plastics sheet, a metal foil or a wire. Binders such as nitrocellulose or polybutadiene may be incorporated in a suspension to assist adhesion of the fibres. The applied layer may be moved from the substrate to form a self-supporting film.

In a metal shear, a work support acts also as a fixed blade with which a movable cutter cooperates and there are means for holding down the work and for compressing it at right angles to the cutting plane. As shown, Fig. 1, a cutter 3 is reciprocable by means of a piston 2 movable in cylinder 1 and actuated by hydraulic fluid supplied through inlet 10 which communicates with an impact hydraulic pressure generator (not shown) such as a hydropunch. An exhaust outlet 12 leads from the exhaust side 11 of the portion. The cutter is also reciprocable by means of a rod 8 which is preferably fluid-operated. A work support 4 also acts as the lower cutting blade. A hold-down 30 and a member 50 for exerting a compressive force axially of a workpiece 27 have similar hydraulic operating mechanisms in communication with the impact generator. In use, the operating rods 8, 35, 55 are actuated to retract the cutter 3, hold down 30 and compression member 50 and their respective pistons fully. A workpiece is placed on the support 4 and the rods 8, 35, 55 are actuated to move the parts 3, 30 and 50 into engagement with the workpiece. Fluid is then supplied to move pistons 2, 33 and 53 into contact with the parts 3, 30 and 50 respectively. High energy cutting then takes place due to pressure from the hydropunch via the passages 10, 38, 58, the relative lengths of which are such that the hold down 30 is actuated first, then the compression member 50 and finally the cutter 3.

If one of these gates is thereby opened an associated toggle TA ... TF is set so as to open associated select gate SL1 ... SL6 and to stop the counter. Once the selection has been made and this has been forwarded to the chosen equipment by virture of an " extend mark " signal EXM, a reset pulse is applied to reset the counter to  zero. The operative toggle may be reset by a signal RMM. Detailed circuits for all the subcircuits are given, these incorporating integrated circuit type MOST devices mounted on jack-in circuit boards.
