Abstract: 407,881. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Carter, P. S. ; Port Jefferson, Long Island, New York, U.S.A.) Sept. 1, 1933, No. 24308. Convention date, Sept. 1, 1932. [Class 40 (v).] The field from a unidirectional aerial system, comprising a radiator a, Fig. 1, and a reflector b, is reversed in direction by varying the effective reactance of the reflector so as to cause the currents induced therein to lag or lead by such an angle that the incident field in the direction a to b is augmented in that direction instead of being reflected. Fig. 5 shows the change in field strength in the two directions as the reactance in the reflector b is altered. As shown in Fig. 6, a V-shaped aerial a, of the kind described in Specification 373,692, is separated from a similar reflecter b bv an odd number of quarter-wavelengths. To reverse the direction of the transmitted field, a switch S, which may be controlled from a remote point, shortcircuits the section from x to S on the tuning- loop of the reflector b so as to alter the effective impedance. Fig. 7 shows three units, of which the centre one a is energized, the two outer ones being provided with short-circuiting switches Sa, Sb. Fig. 8 illustrates a " boosting" arrangement for advancing the phase of the wave from the energized unit a.

Abstract: 501,981. Motor power plant; valves; oil engines. TOTH, C. J. Sept. 8, 1937, No. 24519. [Class 110 (iii)] [Also in Group XXVII] A motor power plant comprises a compression - ignition internal - combustion engine of the twostroke type having a stepped piston Bh, the upper end of which precompresses air admitted to a chamber I bv a. controlled valve K. Communication between the chamber I and the lower working space in the cylinder is by way of piston - controlled ports E. A ring- shaped combustion chamber C surrounds the exhaust valve and communicates with the lower end of the cylinder. Fuel is injected through 'a valve F at a point where the turbulence is greatest in the air compressed into the combustion chamber by the working piston. The exhaust valve is a ported sleeve P operated by a rod T and riding between the inner wall of the combustion chamber casting and a fixed ported sleeve G. The end of the latter is closed by a deflector wall. The quantity of air passing through the ports E is in excess of that required to scavenge and charge the chamber C and serves to cool the combustion products before they pass into the manifold from the several cylinders and thence to the low-pressure turbine. The turbine shaft is geared to the main shaft of the internalcombustion engine.

Filed: 1929-08-16
Abstract: 317,453. Berline, R. M. Aug. 16, 1928, [Convention date]. Mineral and tar oils, purifying.-Liquids such as used switch or transformer or motor lubricating oils are purified by finely dispersing the heated mixture in a centrifugal machine under vacuum or through which passes a current of heated gas or vapour, the current of gas or vapour and the vapours evolved under vacuum being led to a condenser. The mixture may first be centrifuged to remove water and other heavy impurities. For example, used oil is forced by a pump 4 through a heat-exchanger 3 and a heater 2 to the bowl 1<d> of an airtight centrifuge 1 which has collecting receptacles 5. 17 enclosed by a casing 1<a> and is maintained under reduced pressure by a vacuum pump 6. The oil in a highly dispersed state passes to the collector 5, and then to a tank 7 in which a constant level is maintained to preserve the vacuum in the centrifuge, and finally to the heat-exchanger 3 and a delivery pump 9. The vapours from the oil pass through the pump 6 to a condenser 8 and a settling tank 11. In a modified apparatus the mist in the collector 5 is met by a current of hot inert gas from a storage cylinder and a heater, vanes being formed on the inside of the receptacle 5 to increase the. current. The purified oil passes from the receptacle 5 to the tank 7 by a siphon, and the water or other heavy impurity from the receptacle 17 to a funnel and exhaust or other pipe by a second siphon. The cooler is placed before the pump 6. Reference has been directed by the Comptroller to Specifications 204,047, [Class 23, Centrifugal machines &c.], and 252,173.
