IPC: F02M59/36
Filed: 1927-07-20
Abstract: 277,629. Darche, A. A. A. Sept. 17, 1926, [Convention date]. Cam-and-tappet actuated pumps; stroke, varying; buckets; cleaning; priming; singleacting suction valveless bucket pumps. - A fuel pump for motors comprises a differential plunger I provided with an axial T-shaped channel D through which the fuel passes from the inlet pipe G to the annular pump chamber F during the return of the plunger by the spring J. The delivery stroke is effected by a cam S and tappet A, the end B of which is shaped to close the lower end of the channel D. The plunger carries an adjustable stop N for controlling the return stroke, and an elastic buffer Q is arranged between the stop and a screw cap X to prevent jar. By adjusting the cap X the plunger may be adjusted relatively to the tappet A, thus varying the moment at which the tappet engages the plunger and delivery begins. The plunger may be raised out of contact with the tappet to stop the pump. The cam S may be adjusted to vary the stroke of the tappet. The pump may be primed by opening needle valves P, P<1>, and air collecting in the upper part of the chamber F may be removed by opening the valve P. Impurities collected in the chamber E may be removed through a valve P<2>.

IPC: C21B3/04
Filed: 1959-06-05
Abstract: 923,233. Extracting metals. R. RUMMEL. June 5, 1959 [June 7, 1958], No. 19358/59. Classes 72 and 82. In a process for smelting metal-oxide-containing dusts or ores, e.g. Fe 2 O 3 , in finely divided form in two reduction stages, the dust or ore and fluxes, if necessary, are firstly melted in a smelting and initial reduction chamber 1 by introducing a fuel and a gas containing free oxygen into a bath 2, set in turbulent motion by the flow energy inherent in the charged dust or ore, fuel, gas and fluxes (if employed) introduced thereinto (through nozzles 3, 4, 5 and 6 in an arch 7), the metal oxide(s) in the melt is/are transformed into a lower stage of oxidation by a predetermined fuel supply, then secondly the liquid mixture and the gases formed are conducted to another chamber 18 (through a pipe 16), with a smelting bath 20, 21 to which the gases impart heat before leaving, and complete reduction is effected therein by supply of reducing agent. A solid fuel may be employed as the reducing agent for the complete reduction, which may contain no volatile constituents, and may be coke dust. An excess of fuel may be added as reducing agent (through a nozzle or nozzles 26 for the bath 20, 21), which may be discharged with the gases during the two stages and separated therefrom for addition. Preheated air may be used as a gas. The slag 20 is kept at constant level by an overflow channel 23. From the chamber 18 the hot gas flows through a waste heat boiler with heat exchangers and, if desired, through another waste heat boiler, for combustion of any remaining combustible constituents, supplied with preheated air, a steam superheater, air preheater and economiser. Specification 670,769 is referred to.

Abstract: 1286732 Charging cold liquefied gas containers PARKER-HANNIFIN CORP 24 April 1970 [28 April 1969] 19815/70 Heading F4P A closed receiver 16 containing residual liquid nitrogen is charged from a closed liquid nitrogen supply container 2 through conduit means 10, 12, 28, 19 terminating in a spray 21 which serves to decrease the vapour pressure in the receiver 16 and enable it to be charged without the need for venting; the apparatus having means, e.g. a pump 3, for establishing a pressure differential between the container 2 and the vapour space of receiver 16. On putting an operating unit 9 in the "fill" position a solenoid valve 5 in the charging conduit opens to equalize pressure in container 2 and receiver 16 after which a timer 29 switches on a pump motor 30 which forces liquid nitrogen through said conduit means and spray 21. In the event of the temperature and hence pressure in the vapour space of receiver 16 falling below a level sensed by a unit 8 valve 5 partially closes and a valve 6 in a by-pass 14 opens whereof a portion of the pump 3 delivery is warmed in a heat exchanger 4. As shown, sensing unit 8 is adjacent the supply conduit but it may be disposed within the receiver 16. Charging is terminated when a level sensor 23 switches on an indicator lamp 32 and switches off the push motor 30 and closes valves 5, 6. In a modification the pump is dispensed with and the liquid nitrogen supply container is provided with a pressure build-up coil.

Title: Improvements in and relating to liquid-break electric circuit breakers
IPC: H01H33/14
Filed: 1931-07-10
Abstract: 386,322. Oil-break switches; arcrupturing automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Prince, D. C. ; 1424, Wendell Avenue, Schenectady, New York, U.S.A. July 10, 1931, No. 19949. Convention date, July 10, 1930. [Class 38 (v).] A switch is provided with means for mechanically separating the oil-immersed contacts and means, movable simultaneously with but independently of the contact operating means, for .producing a pressure in the oil, whereby oil is forced across the arcing surfaces as they separate, and is then directed away from the arcing space by the suitable construction of one of the contacts. Under predetermined circuit conditions an armature 35 of an electromagnet 34 is released and a spring 25<1> overcomes a spring 40 to rotate a latch 25 about its pivot 26 and drag downwards, by means of a lug 41, a link 27, thus lifting the tubular movable contact 3 of the circuit breaker. At the same time as the circuit breaker is opened, a piston 5 is released and is raised by a spring 7, placing the oil in the lower compartment 20 of the switch casing 1 under pressure. The fixed contact of the switch comprises segmental contacts 15 resiliently carried by a retaining structure 14 in a spider 11. The oil under pressure escapes along a path between the fixed and movable contacts when they separate, up through the tubular contact 3 and through openings 21. A plug 23 in the movable contact 3 and a plug 22 in the retaining structure 14 of the fixed contact facilitate the circulation of the oil. In this way the arc between the contacts is entrapped and the arc products forced out of the contact gap by a forced flow of oil in a radial direction across the contacts. To reclose the switch, electromagnets 42, 42<1> are energized, the former acting through a link 43 and a lost motion connection 44, 45, to recharge the spring 7, and the latter effecting the re-engagement of the latch 25 with the piston rod, so that the spring 40 recloses the switch contacts. The Specification as open to inspection under Sect. 91 comprises also the arrangement shown in Fig. 3 (Cancelled) in which a number of breaks in series are provided, the several switch contacts being contained within an insulating bushing 51 and tubular stationary contacts engaging with cone-shaped movable contacts operated by common operating rods 59. The rods 59 are spring biased towards the surfaces of a cam 68, carried by an operating rod 67 so that when the latter is moved upwardly with the pressure producing piston 56, one operating rod 59 is moved to the right to open one set of series contacts, and the other is moved to the left by the spring bias to open the other set of series contacts. The several break points are tapped from a high resistance to ensure an equal distribution of the potential of the interrupted circuit. This subject-matter does not appear in the Specification as accepted.
