Title: Improvements in or relating to Carburettors for Internal Combustion Engines.
Inventor: MOORE REGINALD
IPC: F02M19/035
Filed: 1917-11-07
Abstract: 120,429. Moore, R., Parsons, P. P., and Stainton, A. V. Nov. 7, 1917. Spray carburettors .- The fuel nozzle 16 of a floatless carburettor has spraying orifices 18 formed in a conical end 17 which forms a seating for a hollow valve 19 which may be lifted entirely by suction transmitted through holes 34, or partly by suction and partly mechanically from the throttle valve 4, or entirely mechanically. The upper end of the valve 19 may have a plane flange as shown, or a conical flange similar to that which rests on the nozzle. The double conical flange facilitates assembling, and provides for interchange of the flanges in case of wear. The nozzle is adjustable axially to regulate the lift of the valve 19 by being screwed at 29 into a rotatable sleeve 23 and itself prevented from rotation by a pin 28 and slot 27. The sleeve 23 rotates over a flanged nut 24, by unscrewing which the nozzle and valve may be removed as a unit. Air, to mix with the fuel as it issues from the orifices 18, may be admitted through holes 39 adjustable by a ring 41 to pass over baffles 45 and through holes or notches 43 in the conical head of the nozzle. This air will also pick up fuel that has fallen on to the baffles. The valve may moreover be closed when the carburettor is inverted, e.g. on aeroplanes, bv a weighted arm which is normally inoperative. The main air supply enters the carburettor at 14 and is controlled by a valve 6. Both valves 6, 4 are spring-loaded and actuated by Bowden wires and the covers 11 of the casings 3, 5 of the valves are secured by segmental lugs 12 which are dropped into grooves in and, after rotation, secured by flanges 13. According to the Provisional Specification, the nozzle housing may be adjusted instead of the nozzle and from a distance by a Bowden wire, and a pilot port may be provided to pass air over the nozzle at starting.

Abstract: 402,829. Subaqueous audible signalling- apparatus. MARCONI INTERNATIONAL MARINE COMMUNICATION CO., Ltd., Marconi House, Strand, and HINTON, N. P., 57, Broughton Avenue, Finchley, both in London. June 10, 1932, No. 16473. [Class 118 (ii).] A magnetostrictive pressure wave transmitter suitable for use in echo-sounding, and subaqueous signalling systems, and for detecting under-water bodies, such as icebergs, comprises a magnetostrictive body of a material, such as steel or cobalt, which exhibits for a steadily increasing magnetic field first an elongation and then a contraction or first a contraction and then an elongation, the body being so proporportioned and suspended and the energizing field being of such amplitude that said body vibrates at a triple or third harmonic frequency with respect to the energizing frequency. The figure shows a magnetostrictive body M suspended midway of its length by knife edges K and by rollers or resilient rubber supporting members R at points one sixth of the length of the body from each end thereof. The natural mode of longitudinal vibration of such a body is indicated diagrammatically by the curve c, the body being three half wave-lengths long. The energizing frequency is made one third of the frequency corresponding to this wavelength. If desired, separate windings for transmission and reception or a common winding for transmitting and receiving may be associated with the body M, the circuit arrangements being as described in Specification 402,828. Alternatively, a separate transmitter and receiver are employed, the receiver being tuned both as regards the dimensioning and method of suspension of the body and as regards the electrical circuit thereof to the harmonic frequency. The return magnetic path for the alternating and polarising fluxes, as also the energizing and/or receiving coils, may be arranged in a manner generally similar to that described in Specification 402,123. Specification 283,116, [Class 118 (ii), Signals], also is referred to.
