Title: Improvements in or relating to the preparation of antifungal antibiotics n-329a and n-329b
IPC: A01N63/28
Filed: 1963-11-25
Abstract: <PICT:1032976/C2/1> <PICT:1032976/C2/2> Antifungal antibiotics N-329A and N-329B, having substantially the same physico-chemical properties as antibiotics nonactin and valinomycin respectively, are produced by cultivating streptomyces tsusimaensis n. sp. especially S. tsusimaensis ATCC 15141 or a mutant or variant thereof in an aqueous nutrient medium containing a carbon source, a nitrogen source and trace inorganic elements at 25 DEG  to 32 DEG  C. under aerobic, preferably submerged, conditions. A typical medium contains corn starch, soybean meal, glycerol, corn steep liquor, calcium carbonate and sodium chloride in aqueous solution of pH 7.0.  Yields of antibiotic N-329A or N-329B vary with temperature, degree of aeration and duration of cultivation. The broth is clarified using a filter aid and the separated cake extracted with a solvent such as acetone. The acetone is removed, the residual crude re-extracted with petroleum ether and the extract concentrated to form crystals, which on recrystallization from acetone, give pure antibiotic N-329A.  The mother liquid is further concentrated, chromatographed on alumina and eluted with petroleum ether. After evaporation of the solvent from the eluate, the residue is crystallized from acetone or methanol to give pure antibiotic N-329B.  The antibiotics are active against bacteria, fungi and yeast and are particularly useful for controlling pathogenic fungus growth on plants (see Division A5). <TABS:1032976/C2/1>ALSO:Germicidal agricultural compositions particularly effective against phytopathogenic fungi comprise antibiotic N-329A (or the closely related antibiotic nonactin) and for antibiotic N-329 B (or the closely related antibiotic valinomycin) in admixture with a solid or liquid carrier.  Optional ingredients are other germicides, fertilizers, soil conditioners or plant growth regulants.  The compositions may take the form of dusts, aerosols, self-emulsifying concentrates, emulsions or wettable powders.

Abstract: 1,125,727. Injection moulding machines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 18 Oct., 1966 [12 Nov., 1965], No. 48132/65. Heading B5A. The nozzle of an injection moulding machine is provided with a closure member 31 (Fig. 5) one end 30 of which lies flush with the end of the nozzle orifice and forms part of the mould surface when the closure member is in closed position, but extends into the mould cavity in the open position. The closure member may be of stepped form as shown at (6) in Fig. 1 (not shown), but is preferably cone-shaped as seen in the remaining Figures. The opening and closing of the closure member may be effected mechanically but may be effected by the pressure of the moulding material. The invention is applied to the moulding of e.g. baths, domes, wall claddings or car body panels. Many examples of moulding materials are given. First main embodiment, (Fig. 5)-Material is forced by a ram (not shown) into a mould cavity 27 through passages 13, channels 14, orifices 16, a chamber 15, and the space between the closure member and its seating 22. The body 11 of the nozzle is of hardened steel, a nose portion 17 of a beryllium/ copper alloy, and a collar portion 21 of stainless steel. The nose 17 is spaced from a mould portion 19 by a heat-insulating ring 18, and a ring 20 formed on the nose 17. Cooling pipes 23 and an electric band heater 25 are provided. A fork-ended lever 40 engages in a groove 39 in the end 38 of a stem 33 of the closure member and enables the stem 33 to be manually or mechanically moved. The lever may be used to indicate movement of the stem. The end 30 of the closure member may be provided with a vent plug (43), Fig. 6 (not shown). Second main embodiment, (Fig. 7)-The nozzle operates in a similar way to' that in Fig. 5. The mould 48, 49 is formed partly by the end of the nozzle. Moulding material is forced from a channel 69 by a ram or screw plunger, through a sleeve valve 71 and into chamber 59 containing the stem of the closure member 63. The stem may carry spiral flutes or vanes 66 and may be prevented from rotating or freely rotatable or rotated by drive means (not shown). Alternatively, vanes may be fixed to the walls of the chamber 59. Movement of valve 71 to closed position assists in keeping the closure member closed. The limits of longitudinal movement of the closure member 63 may be adjustable by means of a worm 91 and a worm wheel 90 mounted on a screwthreaded cylinder 94.
Patent GB-1063539-A (GB)
Title: Chlorosulphonation process
IPC: C08F8/00
Filed: 1965-11-15
Abstract: Polyolefins which are solid at 70 DEG  C. are chlorosulphonated by a process which comprises (a) forming a homogeneous mass of the polyolefin and liquid sulphuryl chloride in the absence of any solvent for the polyolefin or chlorosulphonated product, there being at least 25 parts by weight of sulphuryl chloride per 100 parts of polyolefin, and (b) initiating chlorosulphonation by generating free radicals within the mass.  The polyolefin may be a polyethylene or ethylene/propylene copolymer. Free radicals may be generated by actinic light, X-rays or by heating in the presence of an azo or peroxide free radical catalyst.  Premature chlorosulphonation may be avoided in the homogenization step by adding an inhibitor, e.g. 2,6 - di - t. - butyl - 4 - methyl phenol, 4,41-methylene bis(2,6-di-t.-butyl phenol), alkali metal nitrites and iodine.  The process may be effected in the presence of an inert diluent, e.g. trichlorofluoromethane, dichlorodifluoromethane, chlorodifluoromethane, trichlorotrifluoroethane, dichlorohexafluorocyclobutane and octafluorocyclobutane.  The products may be stabilized, e.g. with epichlorohydrin/bisphenol A condensates, and may be vulcanized, e.g. when compounded with carbon black, lithage, dipentamethylene thiuram tetrasulphide and mercaptobenzothiazole.  In examples polyethylene and ethylene/propylene copolymers are chlorosulphonated with sulphuryl chloride by heating and in the presence of catalysts such as azodiisobutyronitrile, benzoyl peroxide, lauroyl peroxide or azo-dicyclohexylcarbonitrile, in the absence or presence of trichlorotrifluoroethane.

Abstract: 1,023,624. Gating and relay-operating circuits; radio direction-finders. AGA A.B. Dec. 28, 1962 [Jan. 2, 1962], No. 48795/62. Headings H3P and H4D. Relates to a radio direction-finder in which real or simulated circular rotation of a dipole produces a Doppler-effect phase modulation of a received carrier wave, and in which reception at two ends of a diameter is alternately effective. In the embodiment, Fig. 1 (not shown), an array of equi-spaced fixed dipoles (10, 11 . . . 17) is utilized, the dipole ouputs being switched to the receiver in the order 10, 14, 11, 15 . . . According to the invention a first receiver channel is associated with the outputs of dipoles corresponding to rotation in a first path and a second receiver channel is associated with outputs corresponding to rotation in a second path half-a-revolution ahead of the first path, each receiver channel containing means for deriving an output signal, representing the phase modulation, which persists to permit the output signals to be combined with the elimination of any frequency modulation on the received carrier wave. Gating and relay-operating circuits, Figs. 1 and 4 (neither shown).-A train of negative pulses to the input of a three-stage binary counter (27, 29, 30, Fig. 1) effect valve-operated (31, 32, 33) relay switching (34, 35, 36) to open diode gates sequentially to pass dipole outputs in the order 10, 11, 12 . . . to a feeder incorporating a balun. Each diode gate (Fig. 4) incorporates an R.F. choke (49) to isolate the R.F. signal from the D.C. voltage utilized for diode switching. Direction-finding, Fig. 6 (not shown). The I.F. output of the receiver is fed to two similar channels via alternately-operative diode gates (71, 72). Each channel contains a limiteramplifier (75), a phase detector (75) and an oscillator (77) controlled from, and also feeding into as " reference " voltage, the phase detector whereby the phase of the incoming signal is preserved after it has been switched off. The channel outputs are combined differentially in a transformer (85, 86) the output from the secondary winding (87) of which is fed to the control grid of a cathode-ray tube (88) having orthogonal deflexion coils fed in phase quadrative at the frequency of the simulated dipole rotation.

Title: Production of copper-sheathed aluminium or aliminium alloy wire
IPC: B23K20/04
Filed: 1971-10-25
Abstract: 1337341 Making composite wire; bending KABEL - UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 25 Oct 1971 [26 Oct 1970] 49392/71 Headings B3A and B3E A method for the continuous production of copper clad aluminium or aluminium alloy wire includes cleaning the surface of the wire 2 and enclosing it within a strip of copper 9 which is bent to form a tube around it all in a protective atmosphere and then reducing the diameter of the sheathed wire. The reduction in diameter is followed by heat treatment to produce a diffusion layer at the interface between the core and the copper sheath. The aluminium wire is made by casting or extrusion and is supplied from storage means 1, from which it passes to a device 3 provided with brushes 4, 5 in a protective gas enclosure 7. Alternatively there may be provided milling, peeling or shaving devices for cleaning the wire. The copper strip 9 is fed from storage means 10 to a cleaning unit 13, the storage means having provision for welding strips end to end. The strip passes through a drier 14 and a brushing device 15, which has brushing rollers 16 and backing rollers 17. The copper strip is bent into a tube by a roller device 19, welded at a welding station 6, and the sheathed wire is reduced in diameter in means 20 which comprise a drawing ring or reducing rolls. The wire draw-off means may be a disc 21, or an endless band or a clamp and the wire is fed to a collecting drum 22. The wire is further reduced in diameter in stages and heat treated; the heat treatment may take place between successive stages of reduction. The thickness of the diffusion layer between the copper and aluminium depends on the amount of reduction which may be 80% or more, and the heat treatment temperature. Heat treatment is preferably carried out continuously as the wire emerges from the stages of the reduction means.
