Title: Improvements in or relating to coin-freed delivery apparatus
IPC: G07F13/02
Filed: 1923-10-18
Abstract: 225,022. Nicol, P. W., and Yomf Manufacturing Co., Ltd. Oct. 18, 1923. Stroke, varying; fullstroke devices.-Liquid is deliverred from a measuring cylinder d by a piston c connected to a plunger a which is depressed by hand after prepayment and is returned by a spring k acting between two stops m. l on a sleeve S and the plunger respectively, these stops being adjustable to vary the stroke and the amount of fluid discharged. The cylinder d has an inlet valve g, and an outlet valve h in a nozzle f, these being preferably spring-controlled ball valves. The downward movement of the piston closes valve g to cut off supply from a reservoir and opens valve h to deliver the liquid. The return movement automatically closes valve h and allows valve g to open. To ensure a complete return of the plunger a so that it cannot be pressed down again without the insertion of another coin, an arm 4 thereon carries a slider 5 and a hairpin spring 6. During the upward movement of the plunger the spring 6 rocks a pawl 1 so that an eccentric edge 8 makes contact with the slider. Depression of the plunger before the return stroke is completed is prevented by the edge 8 jamming the slider 5.

Abstract: 1,175,813. Cultivating micro-organisms on gaseous hydrocarbons. KYOWA HAKKO KOGYO CO. Ltd. May 30, 1968 [June 2, 1967], No.26017/68. Heading C6F. In cultivating a hydrocarbon-assimilating microorganism in an aqueous nutrient medium under aerobic conditions in the presence of a gaseous mixture comprising a hydrocarbon gas as the main carbon source and oxygen gas, the volume ratio of oxygen gas to hydrocarbon gas supplied to the  culture medium for aeration is so controlled that the amount of oxygen gas is equal to or is less than the amount of the hydrocarbon gas, preferably between 10:90 and 50:50. Hydrocarbon gas: methane, ethane, propane, n-butane, iso-butane, thylene, propylene and butylene. Undissolved gaseous hydrocarbon is recirculated through the fermentation medium. Carbon dioxide in the recirculating gas is absorbed with aqueous alkali. At the beginning of the culturing the upper part of the culturing apparatus contains nitrogen, this is replaced by air and hydrocarbon gas is supplied until the concentration approaches the upper limiting range of combustion, when oxygen is gradually introduced. At the completion of the culturing the supply of oxygen is discontinued, the remaining hydrocarbon gas is replaced by nitrogen and then air is admitted.

Filed: 1960-07-27
Abstract: 940,510. Electric motors. H. M. HOBSON Ltd. Aug. 10, 1961 [July 27, 1960], No. 26125/60. Heading H2A. [Also in Divisions F1 and F2] A submersible booster pump for use in an aircraft fuel tank comprises a pump unit including a casing, an impeller external to the casing and carried on a hollow shaft rotatable in top and bottom bearings in the casing and driven by an electric motor within the casing, and a passage controlled by a non-return valve for delivering fuel from the impeller to the bearings to provide pressure lubrication of the bearings even when the pump is running in a nearly empty tank, the fuel returning to the impeller from the top bearing through the hollow shaft. The impeller 12, Fig. 5, draws in fuel from the tank through a screen 16 and inlet ports 5, Fig. 6, controlled by a rotatable sleeve valve 7, and discharges it through tangential diffuser ducts (not shown) to an outlet 21. Some of the fuel discharged by the impeller 12 passes through a non-return valve (not shown) into an inner casing 2 to lubricate bearings 13, 19. After passing through the bearing 19, the fuel passes through the hollow shaft 20 to the region of the centre of the impeller 12, where it is joined by fuel that has passed through the bearing 13. In the event of an explosion occurring in the inner casing 2, the non-return valve prevents a flash back to the fuel within the tank. To remove the pump from the tank, screws (not shown) securing an access cover 14 to the tank bottom 31 are first removed. The access cover 14 is then rotated to turn the sleeve valve 7 into a position in which the inlet ports 5 are closed, thereby isolating the fuel in the tank from the pump. The fuel in the pump is then drained by removing a drain plug 15. Screws 8 are then withdrawn, allowing the access cover 14 to be removed. After screws 32 have been undone, the inner casing 2, complete with impeller and motor is removed, an electrical plug fitting 17A on the inner casing becoming detached from a socket fitting 17 carried by the outer casing 30. The outer casing 30 remains fixed to the tank bottom 31.

The pipeline has a supporting rope 1 on which are mounted blocks 6 comprising half-blocks 6a, 6b fastened together. Pipes 2, 3, 4, 5 each comprise an inner corrugated metal tube 15, an outer corrugated metal tube 16, a heat insulating layer 17 of expanded polyurethane and a sheath 18 of thermoplastic material, e.g. polyvinyl chloride or polyethylene. The inner tube may have armouring and the outer tube is double-walled. Larger concrete blocks 8, consisting of half-blocks 8a, 8b fastened together, are assembled around certain concrete blocks 6. At appropriate intervals the half-blocks 6a, 6b are attached to rope 1 by a clamp 14 which is fixed to the half-blocks by steel rods 13. In a further embodiment some of the blocks 8 have internal clamps (19) Fig. 3 (not shown) which penetrate into the thermoplastic sheath 18 and thus makes an effective frictional connection with rope 1. In another embodiment the pipe 2 is replaced by a copper-nickel corrugated tube (20), Fig. 4, not shown. When this tube has no liquid therein the pipeline can float on the sea. To sink the pipeline, a buoyancyadjusting agent, preferably n-butane, is introduced and the pressure in the pipe increased until the n-butane, in liquid form, fills the space within the the tube (20). The pipeline then sinks. Other agents are propane and other hydrocarbons vaporisable and liquefiable at ambient temperature.

Abstract: 368,354. Dynamo-electric machines aiding or replacing prime movers. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., Scotswood Works, Newcastle-on-Tyne, IONIDES, P. D., Sproughton, Courtenay Avenue, London, and BECKETT, C. M., 55, Wordsworth Drive, Cheam, Surrey. Sept. 5, 1930, No. 26514. [Class 38 (iv).] Comprises a power plant in which various auxiliary machines are arranged in driving relationship with a dynamo-electric machine, capable of operating as a generator or motor and coupled to a prime-mover through a unidirectional clutch. When the prime-mover is running it drives the auxiliary machines and the dynamo-electric machine as to charge a generator battery. When the dynamo-electric machine is not being driven by the primemover, it runs as a motor from the battery to drive the auxiliary machines. A generator C, Fig. 2, and other auxiliary machines E, F, G are driven from a prime-mover through a unidirectional clutch B. The generator C is connected to a battery H, Fig. 4, through a starter J and has a shunt field C<1> in series with resistances K<1>, K<2> which are normally short-circuited by relays L<1>, L<2>. The primemover has two running speeds and the relays L<1> L<2> are connected with the speed control so that the field is regulated in accordance with engine speed. When the engine is running at low speed both resistances are shorted and battery charging occurs. At full speed relay Ll is open so that increase in speed is balanced by decrease in field and charging occurs. When both relays are open the generator runs as a motor from the battery at a speed above engine speed, and so relieves the primemover of the auxiliary load. When the prime-mover is not running the generator C can be run as a motor to drive the auxiliaries. The dynamo-electric machine has in addition to the shunt field coils, series coils to strengthen its field where the machine is acting as a generator and also maintain the speed at a value near the no-load speed when it is acting as a motor.

Title: Refractory carbides
Inventor: SOWMAN HAROLD G
IPC: B01J2/00
Filed: 1961-07-21
Abstract: Crystalline carbide spherules of uranium carbide, thorium carbide, or uranium (thorium) carbide of diameter 10m  to 125 mils. are prepared by heating discrete irregular particles of these carbides uniformly dispersed throughout a finely divided inert solid isolating medium in a non-reactive atmosphere to above the melting point of the carbide but below that of the isolating medium to form spheres by the effect of the surface tension of the molten carbide.  In a modification of the process, the carbide particles are replaced with irregular particles of the corresponding metal or oxide thereof, and the isolating medium is carbon or contains sufficient carbon to produce the carbide on heating.  The preferred isolating media are boron nitride and carbon, e.g. graphite, carbon black, lampblack, amorphous carbon, or petroleum coke, and the particle size of the medium is at least one order of magnitude smaller than the material to be converted into spherules.  The proportion of isolating material to carbide or carbide precursor can be varied over a wide range, and the non-reactive atmosphere may be helium or argon and the temperature 2300-2700 DEG  C.  The spherules are cooled rapidiy, e.g. by removal from the furnace, whilst maintaining the nonreactive atmosphere. The process may be carried out in a furnace or on a refractory pallet or on a bigger scale using a rotary kiln.  Carbon may be removed from the surface of the spheres produced by treatment with a detergent or alternatively by oxidation under controlled conditions, e.g. by refluxing with chromic acid solution. Adherent isolating medium may be removed from uranium carbide spherules by milling in a ball-mill with an organic solvent, e.g. acetone, and rubber covered steel balls.  Ultrasonic vibrations may also be utilized for cleaning the spherules.  The spherules may be coated with a continuous layer of carbon by the pyrolysis of methane or carbon monoxide at 1300-1700 DEG  C., or plated with metal, e.g. by immersing in an electrolyte of CuSO4 and H2SO4 in a copper dish which is the cathode of the plating cell, a sheet of copper being the anode, the spherules being agitated with a stream of argon during plating.  The spherules are used in atomic reactors as fuel elements, being dispersed in a metallic matrice or being packed in containers. Specification 1,001,360 is referred to.

As shown in Fig.1, every time a contact K c  is closed indicating the passage of a given volume of fluid a pulse generator circuit K (see Division H3) is triggered into producing three pulsed U1, U2, and a longer pulse applied to a gate G. The pulses are applied to the resistors Rt1, Rt2 and a circuit D determines the difference current which is indicative of the difference in temperature. This current is applied to a converter AD producing pulses whose frequency is dependent on its input and the number of pulses passing the gate during the interval of the longer pulse is counted at R. A circuit using two transistors of opposite type is utilized to obtain the difference current, Fig.2 (not shown).  The temperature sensitive resistors may be connected in a bridge circuit.
