Title: Improvements relating to catalysts
IPC: C10G45/08
Filed: 1951-12-13
Abstract: A catalyst for hydrogenation and dehydrogenation reactions, especially the desulphurization of petroleum hydrocarbons, comprises the combined oxides of cobalt and molybdenum associated with phosphorus and fluorine.  A metal oxide support, e.g. activated alumina, may be included, and the catalyst preferably contains 0.1-5 per cent. by weight of phosphorus and 0.1-6 per cent. by weight of fluorine.  The catalyst is prepared (1) by impregnating fluorine-activated alumina with an ammoniacal solution of ammonium phosphomolybdate which may also contain ammonium molybdate and/or ammonium phosphate, and then with a solution of cobalt nitrate (2) by depositing cobalt and molybdenum oxides on fluorine-activated alumina, impregnating with phosphoric acid, ammonium phosphate, aluminium phosphate, or an organic phosphate, and the roasting at 550 DEG C.  Reduction with hydrogen or hydrogen sulphide may be carried out before use.  The catalyst may be employed in the hydrofining of hydrocarbons described in Specifications 654,152, 663,038, 669,536, 669,552, 669,553, 697,222, 697,226 and 697,724.

IPC: A61M16/18
Filed: 1967-06-26
Abstract: 1,193,522. Anaesthetising apparatus. B. R. SUGG and J. PARKHOUSE. 19 June, 1968 [26 June, 1967], No. 29448/67. Heading AST. [Also in Division, F2] An apparatus for administrating anaesthetics comprises a first vaporizer 1 for use in both a draw-over system and a plenum open-circuit system, a second vaporizer 2 for use in a plenum closed-circuit system, said vaporizers being mounted in the main carrier gas flow path which begins at medical gas cylinders 3 and 4 and passes through flowmeters 5 to two-way valve 7 which is operated in concert with twoway valve 8, said valves 7 and 8 constituting a first valve means by which carier gas is selected to flow via either vaporizer 1 or 2. Gas line 9 leads from the atmosphere to the main gas flow path via one-way valve 10 and reservoir 11. Downstream of valve 8, the gas flow path continues as line 12 and has branches connecting with breathing bag 15 and bellows 13. Line 12 leads to breathing mask 18. Exhalation line 20 leads via non-return valve 21 tO a two-way valve 22, which is adjustable to direct exhalation either to the atmosphere via valve 23 or back into gas flow line 12 via line 24 and sodalime canister 25. Said valve 22 constitutes the second valve means of the apparatus, which is adjustable in a single action with the aforesaid first valve means, in such a manner that the apparatus may be operated as a draw-over system, a plenum open-circuit system or a plenum closed-circuit system. Emergency oxygen line 26 is connected between gas cylinder 4 and gas line 12 downstream of valve 8. In the draw-over system, the gas flow from cylinders 3 and 4 is shut off Air, to which a proportion of oxygen may be added, is drawn in through valve 10 and passes through vaporize 1, through gas line 12 to the patient and thence to the atmosphere through valve 22. In the plenum open-circuit system, pressurised carrier gas is fed from cylinder 3 and/or cylinder 4 through valve 7 to vaporizer 1 and thence as in the draw-over system. The back pressure of the carrier gas holds one-way valve 10 closed. If the carrier gas supply fails or its rate falls below the patient's minute volume, valve 10 automatically opens to admit air. An oxygen failure warning device is preferably incorporated in the apparatus. In the plenum closed circuit system., the flow of pressurised carrier gas flows through line 6 to valve 7 and vaporizer 2 and thence to face mask 18. The exhalation passes through valve 22 through canister 25 to gas line 12. Valve 23 enables the patient's lungs to be expanded by operating bellows 13 manually or by powered means, whereupon the small bellows in valve 23 expands and shuts the valve. When the bellows 13 is raised to refill with air, valve 23 opens and expiration from the patient's lungs occurs.

Filed: 1920-10-19
Abstract: 152,663. Moulton, H. C. Oct. 20, 1919, [Convention date]. Blind-stitching machines.-A work-support 53 is yieldingly mounted within a tubular column 55 which slides in guides in a bracket 57 adjustably secured upon the baseplate, 1. The worksupport is pressed upwards by a spring 69 acting upon an arm 68 secured upon the tube. The work-support can be lowered bodily by means of a treadle and lever 74 bearing upon the arms 68. The bender operates within the work support and is raised against the pressure of a spring by means of a lever 92 freely pivoted on a shaft 89 and actuated by an arm 91 fixed on the shaft. To enable the bender to yield if it meets an obstruction, the lever 91 actuates the lever 92 through a spring 94. The shaft 89 is actuated from a cam on a vertical shaft which is given a variable rotary motion by means of a drag-link connection with another vertical shaft not in line with it. The field of vibration of the bender is adjustable by rotating an eccentric sleeve which provides the pivot of the cam-lever. The sleeve is formed with a hand-lever and index. Needles, driving; needles, vibrating laterally. -The needle-lever 12 is pivoted upon a frame 15 pivoted at 16 and oscillated by means of a strut 42 which embraces a cam. The strut is secured to the frame 15 by a nut 44 and a helical spring behind it. A screw 52 may be used to lock the frame from movement and the movement of the strut is then taken up by the spring. The needlelever 12 is oscillated by means of a pitman and a lever 20 linked to a crank on the main shaft. The link also serves to operate the take-up 40.

Abstract: 665,817. Electronic counting apparatus. STANDARD TELEPHONES & CABLES, Ltd. Sept. 26,1947 [Oct. 3,1946], No. 29544/46. Drawings to Specification. Class 106 (i). A pulse counting device as described in Specification 665,818 comprising a cold cathode gasfilled sequence electric discharge tube of the type described in Specification 639,827, [Group XL (a)], is operated with a pulse rate such that the tube is unable to deionize between successive pulses. Sufficient time for deionization is obtained by arranging the time constant of the condenser, connected across the last gap of the tube, and the associated impedances, so that one or more pulses following the pulse which fires the last gap are unable to fire any gaps of the tube, or by using two tubes alternately, or by applying to the tube in opposition to the standing interelectrode potential, a source of square pulses, synchronized to the discharge of the last gap so as to hold the tube inert for the requisite time. The device is thus able to count to a radix greater than the number of gaps in the tube. The discharge maintaining battery may be omitted provided that the pulse amplitude is raised so that the gaps will fire without the assistance of the constant potential.
