Title: Injectionable Substance
Inventor: BROWN ETHAN ALLAN
IPC: A61K9/00
Filed: 1966-07-08
Abstract: 1,155,036. Injectionable substances. E. A. BROWN. 8 July, 1966, No. 30836/66. Heading A5B. Therapeutic compositions for injection comprise finely divided solid microparticles of a metabolizable substance having an active drug physically incorporated into the structure of said micro-particles, said micro-particles being suspended in a physiologically accepted or non-toxic liquid carrier. The carrier is preferably aqueous or an oil, and when the latter is used the suspension may subsequently be suspended or emulsified in an aqueous medium; alternatively, the carrier may be a secondarily active substance, e.g. solutions of antihistamines, corticosteroid hormones and/or antiserum. The microparticles may be those of a protein, proteose, protamine or amino acid, preferably glycine or tyrosine. The microparticles incorporating the active drug may be encapsulated with for example celluloses (e.g. cellulose acetate or butyrate, methylcellulose, hydroxyethylcellulose or ethylcellulose); low molecular weight polymers of polyethylene, polypropylene, methylmethacrylates or methacrylates; gelatin; silicone derivatives; or salts (e.g. NaCl, KCl or CaCl 2 ), employing conventional methods. The active drug may be incorporated in the micro-particles by dissolving the metabolizable substance in a liquid (eg water) containing an active drug dissolved therein; depositing the metabolisable substance having the active drug incorporated therein from the liquid (e.g. by lyophilization or by precipitation from a saturated solution of the metabolizable substance in the liquid); drying the metabolizable substance and breaking up the particles to micro-size, and finally suspending the metabolizable substance in the carrier. The invention is particularly applicable for administering drugs which are normally likely to produce adverse side-effects such as allergens, antigens, venoms, vaccines, toxins, serums and extracts of pollens, moulds and animal danders; and also vitamins such as C and B 12 , antitussives, antihistamines, analgesics, narcotics, hypnotics, sedatives, tranquillizers, hormones and insulin.

Title: Electrolytic hydrometallurgical process to recover copper from sulphide ore concentrates
IPC: C25C1/12
Filed: 1973-06-28
Abstract: 1407520 Fe and Cu salts; jarosites E I DU PONT DE NEMOURS & CO 28 June 1973 [28 June 1972 27 Sept 1972 4 June 1973] 30885/73 Heading C1A [Also in Division C7] A Cu-containing mineral is treated in the presence of Fe and S with both HNO 3  and H 2 SO 4 , and the resulting solution containing Fe and Cu ions is treated to reduce sufficiently the content of Fe<SP>3+</SP>, NO 3 <SP>-</SP> and other impurities before electrowinning to allow production of Cu having a conductivity at least 100% of the I.A.C. Standard. The Fe<SP>3+</SP> content may be reduced below 5 gpl. and the NO 3 <SP>-</SP> below 1 gpl. The mineral may or may not contain Fe, e.g. CuFeS 2 , Cu 5 FeS 4 , Cu 2 S or Cu 9 S 5 ; additional Fe<SP>3+</SP> may be added if desired or required to assist to solubilize Cu, giving Fe<SP>2+</SP> which removes NO 3  through being oxidized thereby to Fe<SP>3+</SP>. Excess Fe<SP>3+</SP> may thereafter be removed by precipitation as a jarosite, e.g. by adding NH 4 OH. Remaining Fe<SP>2+</SP> may also be removed at this stage by conversion to Fe<SP>3+</SP> with air, the Fe<SP>3+</SP> being precipitated. Both NO 3 <SP>-</SP> and Fe<SP>3+</SP> removal may be assisted with heat and pressure. A multi-stage continuous treatment may be used with mineral concentrate and acid mixture in countercurrent. Other impurities may be removed as follows; Se or Te by treatment with Cu powder; Zn by preferential leaching with the spent electrolysed solution or by precipitation as ZnS. Build up of impurities in a continuous process involving recycling is avoided by continuous purging, e.g. of 10% of the spent electrowinning solution.

Abstract: 192,832. Vickers, Ltd., Hibberd, C. E., and Goad, F. L. Nov. 23, 1921. Gas, supplying by meter. - In apparatus of the screw-and-nut type in which the screw and nut can automatically disengage against the action of a spring to prevent damage should the valve fail to cut off the supply completely, the inherent resiliency of the valve-closing mechanism and the supporting brackets therefor is utilized to allow the disengagement and cause the reengagement of the screw and nut. As applied to the mechanism described in Specification 165,483, a portion 20 of the thread at the end of the screw p is removed to allow the screw to rotate in the nut m without longitudinal movement of the valve 11 fails to cut off the supply completely. The natural resiliency of the valveclosing lever 23 and the supporting brackets 24 causes the screw and nut to re-engage when further coins are inserted. The other end of the screw has a plain portion 21 to prevent damage if too many coins are inserted. In this case the screw and nut are re-engaged in known manner by a spring 22.

Title: Improvements in the manufacture of artificial fibres
IPC: D01G1/00
Filed: 1920-11-06
Abstract: For the manufacture of "staple fibre," a large number, say 200, of untwisted spun filaments are formed into a composite strand in which the filaments are arranged in a parallel and ordered fashion, the strand is then led directly from the precipitating bath to a winder on which it is cross-wound to form a skein, and after drying under tension either on the winder or after transfer to a separate stretching frame, the skein is cut up into lengths.  The fibres being arranged in an ordered and parallel fashion, are particularly suitable for the manufacture of yarn, either of these fibres alone or mixed with other textile fibres; the product is of a silk-like character and shows the softness and brightness of artificial silk. The filaments, at the exit end of the precipitating-bath, are collected by a guide, and are distributed in an even and open manner to the winder by reciprocating the latter or the guide; the full-sized skein so produced is preferably at once crosslaced in three equidistant places, and preferably while still on the winder, is washed, dyed, &c., by revolving the latter over suitable baths into which the lower side of the winder dips; or the winder as it is receiving the strand, may dip into a washing-liquid; before the final drying, one or more of the arms of the winder are extended by the introduction of a distance piece, to place the strand under tension. Specifications 9017/03, [Class 120, Spinning], 10211/10, 121,734 and 135,206 are referred to.
