Title: Improvements in or relating to transistor gate circuits
IPC: H03K17/16
Filed: 1959-07-14
Abstract: 922,536. Switching magnetic recording heads. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 14, 1959 [July 17, 1958], No. 24162/59. Class 40 (2). [Also in Groups XIX and XL (c)] In a recording head switching circuit of the type in which pulses are fed through the collector circuit of a transistor under the control of signals applied to the base to an inductor constituted by the " write " head of a drum store connected in the emitter circuit, the back voltage developed across the inductor by the leading edge of the pulses is prevented from cutting off the transistor by applying a sufficiently large control signal to the base to store excess free charge carriers in the base so that conduction continues in the emitter-collector path even though the emitter base circuit is temporarily reversely biased. In Fig. 2, clock pulse signals are fed to the writing head 132 of a magnetic drum recorder when gating signals applied to resistors 27 and 213 have rendered the transistors 2 and 13 conducting. The leading edge of the signals produces sufficient back voltage across the head to cause the emitter-base circuit of transistor 2 to be reversely biased but the gating pulse applied to the base of the transistor is of such amplitude that the excess charge stored in the base zone will permit conduction through the emittercollector path to continue. The back-voltage which is produced at the trailing edge of the input pulse is prevented from producing a large forward bias at the emitter base junction of transistor 2 by inserting an inductor 25 in series with the base, a rectifier 26 preventing overswing in this inductor. The writing head 132 is one of a number of heads which may be selected by the application of pulses to the base of an appropriate pairs of transistors such as 2 and 13 arranged in a matrix (Fig. 1, not shown).

Title: Process for removing nitrogenous compounds from hydrocarbon oils
Inventor: WEBSTER ALFRED BENTLEY
IPC: C10G17/02
Filed: 1955-08-25
Abstract: Nitrogenous compounds are removed from hydrocarbon oils by treating with phosphoric acid in the liquid phase, separating the oil from spent phosphoric acid, mixing water and a volatile water-immiscible organic solvent, and, if required to ensure phase separation, a volatile water-miscible organic solvent with the spent acid; separating the aqueous phase and distilling to remove any water-miscible solvent present and such a quantity of water as to leave as residue a phosphoric acid of sufficient strength for rinse. The phosphoric acid may have a concentration of 80-95 per cent H3PO4. Water-immiscible solvents referred to are volatile hydrocarbons, such as gasoline, petroleum spirits, naphtha, benzene, xylene, toluene, hexane, heptane, octane, cyclohexane and methyl cyclohexane; chloroform, carbon tetrachloride, dibutyl ether, dimethyl carbonate and tri- or tetra-chloroethene.  Water-miscible solvents specified are ketones, alcohols, ethers or esters, e.g. methyl, ethyl, isopropyl, n-propyl and tertiary-butyl alcohols, acetone, methyl ethyl ketone, methyl acetate and formate, methylal, dioxane and ethylene glycol monomethyl ether.  The ratio of oil to phosphoric acid may be 100:1 to 1:1.  The oil may be separated from the spent acid by centrifuging or settling, and may then be washed with water or alkali, e.g. dilute caustic soda, or treated with adsorbent clays, with or without a solid alkaline material such as lime.  Sufficient water may be added to the spent acid to dilute it to 25-60 per cent H3PO4.  The water-immiscible phase may be treated to recover the solvent and the extracted nitrogenous compounds.  Mineral lubricating oils, gas oils, diesel fuels, jet fuels, gasolines and fuel oils may be treated.

Abstract: 810,876. Welding by pressure. CROMPTON PARKINSON Ltd. July 30. 1957 [Aug. 10, 1956], No. 24608/56. Class 83 (4). A machine for welding studs to a tube along a helical path has a driving mechanism for intermittently rotating the tube and for intermittently moving a carriage along the tube and a stud welding head on the carriage which each time the tube and carriage come to rest welds a stud to the tube. A motor 3 intermittently rotates two tubes 1 and traverses the carriage 5 carrying a vibratory hopper 6 and two welding heads 8. Studs are fed from the hopper 6 down guides 7 and are pushed by cam-actuated members 19 between the water-cooled jaws 35, 36 of each welding head. One jaw 36 is carried by and spring loaded towards the other 35 which is clamped on to a dove-tail portion of the welding head. Each stud as it is pushed between the jaws engages a curved surface 25 to lift the jaws from the tube 1. Under control of a cam, welding current is connected up and solenoids retract the welding heads to strike the arcs. The studs are then welded to the tubes, the welding heads moving down tmtil an insulated pad 37 on the fixed jaw 27 engages the tube. Relative movement of the welding heads and tubes disengages the welded studs 41 from the jaws 35, 36. In a modification the moving jaw 36 is pivoted to the fixed jaw 35 and a weight on an arm fixed to the moving jaw supplies the clamping pressure to hold the stud.

Abstract: 682,941. Photographic stripping films. BRITISH TRICOLOUR PROCESSES, Ltd. Sept. 8, 1948 [Sept. 9, 1947], No. 24745/47. Class 98 (ii). A multilayer stripping film comprises a support as of cellulose nitrate or acetate carrying on one side at least two differentially sensitized silver halide emulsion layers separated by a layer comprising a copolymer of an alkali metal salt of acrylic and/or methacrylic acid and an ester of acrylic and/or methacrylic acids. The copolymer materials are prepared by reaction of the monomers in aqueous dispersion or emulsion in presence of a catalyst and preferably at raised temperatures, as by the methods of Specifications 437,446; [Group IV], and 648,001, [Group IV (a)], and are applied to the emulsion layer or layers to form the stripping layers in dispersion form without use of organic solvent. Plasticizers such as dibutyl phthalate, methyl glycol phthalate, glycerol monolactate diacetate or triethylene glycol dihexoate may be included in the dispersions. Copolymers of sodium methacrylate with methyl methacrylate are especially preferred. The stripping layers are soluble in alkali or alkaline developer but should possess sufficient adhesion not to strip before development of the outer image, and proportions are specified to give choice of 1.5, 5, and 11 minutes soaking before stripping occurs. Copolymers containing a higher proportion of the sodium salt, which strip more readily, are used between the outer emulsion layers of a material having two or more stripping layers. Two- and three-emulsion layer camera films for two- and threecolour work containing respectively one and two of the stripping layers are described. The polymers constituting the stripping layers adhere sufficiently to an underlying silver halide emulsion layer as not to require introduction of a separate material of adhesive character. Specifications 437,446, [Group IV], 575,512, and 638,308 also are referred to.
