Title: Improvements in or relating to cryotrons
IPC: H01L39/18
Filed: 1959-03-26
Abstract: 908,704. Superconductor circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 26, 1959 [March 31, 1958], No. 10647/59. Class 40 (9). [Also in Group XXXVI] Fig. 5 shows a cryotron arrangement which may form part of a logical circuit comprising two mutually insulated parallel surfaces represented by Figs. 5a and 5b, respectively mounted on a support member. They are superposed with gate elements designated a lying directly above or below correspondingly numbered control elements b. The voltage applied across terminals 15, 16 and 151, 161 produces currents which, if all the gates are superconductive are sufficient to render gates 13a, 14a normally conductive, and which if one gate in either circuit is normally conductive are insufficient to render the controlled gate in the other circuit normally conductive. Operation is as follows: If a pulse is supplied at 17, 18 to render gate 11a normally conductive gate 14a goes superconductive and the current in control conductor 13b switches gate 13a to the normally conductive state. Circuit 15<SP>1</SP>, 16<SP>1</SP> is then normally conductive and 15, 16 superconductive and this condition persists on removing the pulse. If now a pulse is applied at 17<SP>1</SP>, 181 to render gate 12a normally conducting current through control conductor 13b is reduced to allow gate 13a to revert to the superconducting state whereupon the current through limb 15<SP>1</SP>, 16<SP>1</SP> now entirely superconducting switches gate 14a to the normal state. The condition also persists on removal of the pulse.

Abstract: 452,456. Purifying liquids; swimming-baths. AULD, B. H., 66, Victoria Street, Westminster. April 8, 1935; No. 10872. [Classes 26 and 46] In sterilizing water or other liquid, which is spread over a large area with varying depth as in a reservoir, swimming pool or bath,.by means of ozone or other gas, the gas is admitted through pipe outlets of size varying at different levels so that less of the gas escapes at a higher than at a lower outlet. The area of an outlet may be proportional to the head of liquid above it. Figs. 1 and 2 show a swimming bath with sloping bottom to which the water is supplied down a cascade 22. Ozone is supplied through a header 24 at one side of the bath and branch pipes 26 in groups, the members of which extend for different distances across the bath, the outlets from branches of each group being of the same size, but of a different size from those of other groups. The water may be supplied to the cascade through a rising main 34 to which ozone may be admitted through a branch with an elbow inside the main pointing in the direction of flow. Fig. 7 shows a bath to which ozone is supplied through three headers 40, 41, 42, the headers 40, 41, being arranged longitudinally in the centre of the bath and having transverse branches 44, while the header 42 extends transversely at the deep-end of the bath and has longitudinal branches 46. The headers are connected to a main feeder 48 and have separate control valves. Fig. 11 shows an arrangement in which water is supplied from a filter 58 through a main 60 to both ends of the bath through branches 62, 64. Some of the water flows through a byepass 66 with pump 68 and injector 70 by means of which air is drawn in through a drier 82, an ozonizer 73 and a pipe 72. A vacuum regulator 78 connected to the pipe 72 is sensitive to the sub-atmospheric pressure at the injector 70 and controls the electricity supply to the ozonizer.

Title: Improved textile and other materials of organic derivatives of cellulose and processes for their production
IPC: D06M13/188
Filed: 1935-04-09
Abstract: Permanently delustred textile materials, foils, films, and the like of organic substitution derivatives of cellulose are obtained by subjecting the materials to local or uniform delustring treatment with hot aqueous liquids or moist steam and then subjecting the delustred materials to esterification treatment so as to render the delustring permanent.  The products are resistant to the relustring action of wet ironing and other laundering treatments, and under a lens they still have the crazed appearance characteristic of cellulose acetate artificial silk which has been delustred with boiling water or moist steam.  The products have increased resistance to further delustring by hot or boiling aqueous liquids, and the affinity for dyes, particularly dispersed insoluble dyes is modified. The process may be applied to cellulose acetate or other cellulose ester material, and the esterifying agent may be acetic, propionic, or butyric anhydride. The anhydride is diluted to suppress its solvent power and reduce its relustring power preferably so that there is little or no change in lustre during esterification. Hydrocarbons such as toluene, benzene, xylene, and kerosene, or carbon tetrachloride, or higher aliphatic ethers, are specified diluents.  Sulphuric, phosphoric, perchloric, hydrochloric, and hydrobromic acids, ferric, stannic, and zinc chlorides and bromides, sodium and potassium acetates, are specified catalysts.  The material may be treated with a solution of catalyst and dried before being treated with the esterifying mixture.  Yarns may be treated in hank form or as open wound packages, or as woven, knitted or other fabrics. The reaction may be carried out at raised pressure and temperature.  Differential dyeings may be obtained on mixed fabrics containing treated and untreated yarns, or treated yarns and other types of yarn such as cotton, regenerated cellulose yarn, or animal fibres.  Local effects are obtained by printing a fabric with a wax or other resist, delustring by treatment with boiling soap solution, removing the wax or other resist, and subjecting the whole fabric to acetylation.  In examples, cellulose acetate fabric is delustred with boiling soap solution, and then treated with a mixture of acetic anhydride, benzene, and ferric or zinc chloride with or without hydrochloric acid, or with acetic anhydride and xylene.  In another example, cellulose acetate fabric is printed in a design with molten resin or colophony, treated with hot water to delustre the untreated parts, then with xylene to remove the resin, and then with an acetylation mixture.

Patent GB-1067638-A (GB)
Title: Recovery of nickel from nickel-containing materials
IPC: C22B23/06
Filed: 1966-03-14
Abstract: Ni-containing material is activated for the extraction of Ni therefrom as nickel carbonyl by treatment with CO2 by forming from it a molten bath containing 0.2-4% S, not more than 3% Fe and not more than 45% Cu, the S content not exceeding 2% when the Cu content is less than 15%, the balance nickel and impurities, and quenching the bath to form fine-grained metal particles throughout each of which the S is intimately and uniformly distributed.  The molten bath may be produced from molten Ni-containing sulphidic material by mechanically agitating the material and simultaneously directing a stream of oxygen on to the surface thereof to reduce the Fe content to below 0.5% and the S content to below 5%.  The oxygen treatment is then stopped and the agitation continued until the S content is reduced to the desired level.  Quenching of the bath is effected by directing a high-velocity stream of water against a stream of the molten bath or by bringing a stream of the molten bath in contact with a water-cooled copper surface.  Carbonlyation may be performed at 150-350 DEG F and at pressures not exceeding 100 atmospheres.ALSO:Fine grained Ni-containing particles, throughout each of which the S is intimately and uniformly distributed, are produced from Ni-containing sulphidic material (see Division C7) and used as feed material in the production of nickel carbonyl. Treatment with CO2 may be effected at 150-350 DEG  F. and pressures not exceeding 100 atmospheres.
