Title: Improvements in or means for feeding a supply of lubricant through an induction system of an internal combustion engine
IPC: F01M1/04
Filed: 1938-11-10
Abstract: 521,448. Lubricating internal combustion engines. THOMAS, A., and GUY, W. E. Nov. 10, 1938, No. 32601. [Class 12 (iii)j . Upper cylinder lubricant is admitted to the starter jet air passage of the carburetter of an internal-combustion engine when the strangler valve controlling the starter jet is operated. In the apparatus shown a partial withdrawal of the strangler rod 16a mounted on a vehicle dashboard opens a valve 15 against the resistance of weak spring 19 to connect a flexible tube 4 leading from a lubricant reservoir 1 to flexible tubes 20, 21 leading respectively to a tube 9 opening into the air passage 6 of a starter jet orifice 13 of a carburetter and to a point in the induction passage adjacent the carburetter throttle valve. When the withdrawal movement of the rod 16a is completed a plunger 11 is raised against the resistance of stronger spring 12 to open the inlet 23 from the passage 6 to the induction passage. A spring-pressed valve 10 prevents the escape of lubricant from the tube 9 until suction occurs in the passage 6. The rod 16a may be held in its partially withdrawn position if given a slight turn so as to cause a projection 16d in the bush 16b of the rod to engage with a groove crossing a longitudinal groove in the rod. Lubricant can then pass through the tube 21 to the induction passage. The lubricant supply may be adjusted by a valve 5 on the reservoir 1. A sight tube is fitted in the feed pipe 4. In a modification the tube 20 is connected to a tube 26 fitted with a non- return valve 27 and projecting at right angles from a tube 24 which is screwed into the hole in the starter jet passage normally receiving the air adjusting screws. The airadjusting screw 25 is instead fitted in the end of the tube 24. Means may be provided to allow only a measured quantity of lubricant to be supplied at one period and the feed pipe may be controlled by a valve operated by solenoid in circuit with the engine starter.

Abstract: 366,949. High -tension switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Oct. 31, 1930, No. 32855. Convention date, Oct. 31, 1929. [Class 38 (v).] Pneumatic blow-outs ; pneumatic actuation.-- Gas-blast switches have their break-point a<1> arranged at the outer ends of obliquely-arranged insulators h<1> and interconnected by a lead e and contacts d<1> bearing on the movable contact rods c<1>. The latter are coupled by rods i<1> to a crosshead on a hollow rod k carrying a piston r in a cylinder s. Compressed air is admitted through an opening o and ports m<1>, m<2>, m<3> in a hollow guide n for the rod k, and passes through an opening q to the upper side of the piston r, which is thereby moved downwards to open the switch. As the opening movement is performed, air is cut off by the successive closure of ports m<1>, m<2>, m<3> by the descending tube k, thereby obviating a shock at the fully-open position. Air also passes through the tubes h<1> to provide the blow-out effect. Closure is effected by admitting air through the opening t beneath the piston. Reference has been directed by the Comptroller to Specification 356,221.

Title: Apparatus for generating combustion gases under pressure
IPC: F02K7/00
Filed: 1962-08-27
Abstract: 960,297. Gas turbine plant; jet propulsion plant; generating combustion products under pressure. W. MANS. Aug. 27, 1962, No. 32860/62. Headings FIG, F1J and F1L. An apparatus for generating combustion gases under pressure comprises an air suction device fed by part of the gases produced by the apparatus and constructed to accelerate the air to sonic or supersonic velocity and at least one combustion chamber arranged around a compression device comprising consecutive stagnation chambers, each of which is connected via Venturi nozzles with the next stagnation chamber and in which the first stagnation chamber in the direction of air flow is connected to the outlet of the air suction device and the last stagnation chamber terminates in the combustion chamber such that under the influence of heat transfer from the combustion chamber the air in the stagnation chamber is compressed. A combustion apparatus, Fig. 1, for an aircraft comprises a jet pump 1 fed by gas from a combustion chamber 2 which escapes with supersonic velocity through a pipe 4 and induces atmospheric air through pipe 3 into a mixing tube 6, the gas-air ratio being controlled by a movable cone 5. The pressure of the mixture is increased in stagnation chambers 7 connected by staggered Venturi nozzles 7<SP>1</SP>, 7<SP>11</SP> &c of successively decreasing cross-section, each nozzle accelerating the gas flow to supersonic velocity. Compression is increased by heat transfer from the combustion chamber 2, or additional combustion gas may be supplied to the nozzles 7<SP>1</SP> to reduce boundary layer losses, or fuel may be injected directly into the stagnation chambers 7. The gas-air mixture flows from the chambers 7 into the combustion chamber 2 containing a fuel burner 10 and after combustion part of the gas produced flows to a chamber 17, in which additional fuel is supplied, and to a jet propulsion nozzle 11, controlled by a movable cone 16. At high flight speeds surplus air is discharged from an annular chamber 12 through a propulsion nozzle controlled by a cone 13. Combustion of additional fuel may occur in this nozzle. Starting is effected by closing annular valve 15 and supplying air or gas through valve 14. In a modification for a stationary engine, Fig. 2, the jet pump 1 is replaced by a compressor (not shown) driven by a turbine 18, and a separate power turbine 19 and a second combustion chamber 17 are included.
