Filed: 1971-04-19
Abstract: 1348994 Toothed gearing PHILIPS GLOEILAMPENFABRIEKEN NV 19 April 1971 [2 April 1970] 25621/71 Heading F2Q To maintain the centre distance between two parallel gear-wheel shafts against radial pressures each meshing wheel has an untoothed surface and a single spacing ring is interposed between them. Externally and internally toothed wheels 2, 3 have circumferential grooves 4, 5 in which a ring 7 rolls on the bottoms 8, 10 thereof to maintain the correct spacing of the wheels. The depths of the grooves is greater than the corresponding tooth depth so that radial forces are taken by the ring 7. In a modification the gear-wheels have axially extending untoothed surfaces at each side of the teeth each receiving a single spacing ring. The invention may be applied to two externally toothed engaging wheels and to gearings such as planetary gear bores having more than two engaging wheels.

Abstract: 441,414. Controlling motor vehicles. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H., Titanic Works, Lincoln. Sept. 7, 1934, No. 25799. [Class 79 (v)] [See also Group XXXIV] The service pipe 2 leading from the engine induction pipe 1 or other source of vacuum to the brakes or other vacuum operated devices on road vehicles is connected to a reservoir 5 by a valve device 6 which while permitting flow of air from the pipe 2 to the reservoir through a non-return valve 13 wherever the pressure in the pipe rises above that in the reservoir, prevents withdrawal of air from the reservoir except when the pressure in the pipe falls below a preset limit. For this latter purpose, a spring-pressed valve 7 is provided, controlled by a diaphragm 9 subject on one side in chamber 12 to the pressure in pipe 2 and to atmospheric pressure on the other side. Normally, the reservoir 5 is available to assist the operation of the brakes &c., but should the effective vacuum therein have been lowered, the reservoir is isolated by the valve 7 so as to prevent weakening of the vacuum in the pipe 2. A non-return valve 3 is interposed between the pipe 2 and the source 1.

Filed: 1947-09-24
Abstract: 656,524. Valve receiving circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 24, 1947, No. 25951. Convention date, Oct. 8, 1942. [Class 40 (v)] A high frequency converter comprises a triode, a resonant cavity associated with the grid and cathode, means for feeding the signal frequency and local frequency to the cavity, # the local frequency being (1Œ-) times the signal frequency where # is an odd integer and # an even integer, means for tuning the cavity to be resonant to both the signal frequency and the local frequency, and means for extracting the intermediate frequency from the anode. In Fig. 5 the cathode and grid of the lighthouse triode 6 are coupled respectively to the outer and inner conductors 4, 5 of a coaxial line. The line is tuned by plunger 44 to be resonant to both the signal and the local frequencies. This may be done by making its effective electrical length equal to where #s, # i  are the wavelengths of the signal and local frequencies. The signal frequency is fed in by a transmission line 36, 37 to a probe 38 which is adjustable for matching purposes. The local frequency is fed in by a coupling loop 52. The anode of the valve is connected to the inner conductor 62 of a coaxial line, the outer conductor 5 of which is connected to the grid, which is tuned by a plunger to be resonant to the intermediate frequency. In a modification, Figs. 1 and 2 (not shown), this tuned line is omitted and the output is obtained direct from the anode. In Fig. 8 the grid-cathode line is replaced by a waveguide 69 provided with a tuning plunger 75 and an adjustable probe 93 which can be used to neutralise any reflections from the valve. The Specification as open to inspection under Sect. 91 also describes a modification of Fig. 8 using a diode instead of a triode. This subjectmatter does not appear in the Specification as accepted.

Title: An improved carburetter for use with heavy oils
IPC: F02M61/00
Filed: 1920-09-20
Abstract: 151,607. Rona, I. Sept. 23, 1919, [Convention date]. Spray carburettors.-Heavy fuel is converted into spray by means of compressed air admitted during a portion only of the suction stroke, two parallel controlled paths being provided in the nozzle for the compressed air, and one of the paths being controlled in accordance with the engine speed. The amount and duration of the compressed air supply is controlled by one or more rotary valves driven by the engine. The mixing-chamber 1 is supplied with atmospheric air past a spring-loaded valve 2 and through a passage 3 which surrounds the spraying-nozzle. This comprises a casing 10 enclosing a hollow fixed part 9 so as to leave an annular passage 8 which communicates through a passage 7 with a heavy-fuel float chamber 6. The casing and its enclosed part 9 are traversed axially bv a partly hollow valve-spindle 15 terminating in a nozzle 5, the spindle being provided with a collar 16 adapted to close the lower aperture 17 of the part 9. Compressed air, supplied at 11. reaches the annular space 13, and may proceed through both the annular passage 8 to spray the heavy fuel therein and also through the part 9 unless the aperture 17 is closed by the collar 16. The spindle 15 is actuated through a stop 19, after starting, from the valve 2, which is moved by hand or governor acting upon a flange at the lower end thereof. At starting, the valve spindle is raised to shut off the compressed air supply to the mixing- chamber 1 and to cause a port in the spindle to register with a passage 22, which is fed through a passage 21 from a light-fuel reservoir 20. Thus light fuel is delivered to the nozzle 5 and is sprayed by air drawn in by suction past the partly open valve 2, the compressed air 'being cut off. To run on heavy fuel after starting, a shaft 26 is rotated and lowers the spindle 15 through an arm 25 and disk 27, thus cutting off the light fuel and permitting the compressed air to flow through passage 8 supplied with the heavy fuel. With increasing speed the spindle is lowered so that the collar 16 gradually closes the aperture 17, thus causing most or all of the compressed air to pass through passage 8. Thus when the compressed air is flowing for the shortest time it is most effectively used for spraying the fuel, and the mixture strength is thereby maintained constant. The fuel chamber 6 may be heated by an exhaust jacket 33. Compressed air is distributed by a rotating valve 28, Fig. 4. communicating at 29 with the compressor and being recessed at 30 to determine the interval during which air shall be supplied through outlet 32 to pipe 11. With a multi-cylinder engine, more than one valve may be employed to prevent overlapping of the injection periods of the several cylinders.
