Abstract: 804,024. Working cycles; cylinders; valves and valve gear; regulating. COOPERBESSEMER CORPORATION. Feb. 10, 1956 [March 14, 1955], No. 4209/56. Classes 7(2), 7(3) and 7(6) A gaseous main fuel charge commencing to enter a main combustion space 30, Figs. 1 and 2, just before an air charge therein reaches full compression is dispersed and ignited by a stream of hot gases formed by ignition in an auxiliary combustion chamber 5 of a fuel/air mixture too lean for self-ignition. The invention is applicable to four-stroke engines but a twostroke engine is shown. The main charge is supplied from a high pressure (800 to 1000 1bs. per square inch) source 16 via a non-return valve 23 and a valve 14 the return spring chamber of which has a vent 22. The lean fuel/air mixture is ignited by a spark-plug 22 or a pilot injection of oil and is formed by charge air mixed with gas supplied from a source 9 via a non- return valve 11 and a valve 6. The valves 6, 14 are conjointly operated by a rocker 26 having a return spring 27. The valve 6 may open fairly early or late in the compression stroke, the valve 11 closing when the cylinder pressure exceeds the supply pressure of 100 or 200 lbs. per square inch respectively. The lean fuel/air mixture is ignited from 2 to 15 degrees before top dead centre, and the main fuel supply commences from 8 to 15 degrees before, and ends from 10 to 15 degrees after, top dead centre. Piston-controlled exhaust and air inlet valves are provided. The engine may be fuelled by natural gas or by methane, ethane, propane, butane, hexane, pentane or mixtures thereof. Regulation may be effected by varying under governor control the pressure and therefore quantity of the main gaseous charge only, the gaseous charge quantity supplied to the chamber 5 remaining constant at all loads and being preferably less than is necessary to operate the engine at idling. Reliable low-load running is thus achieved.

Filed: 1927-02-17
Abstract: 266,359. British Thomson-Houston Co., Ltd., (Assignees of McNairy, J. W.). Feb. 18, 1926, [Convention date]. Cut-out arrangements.-Relates to an arrangement of transformers T<1>, T<2> or reactances which are excited almost to saturation by a, direct current in secondary or independent windings S<1>, S<2> and energized also by primary windings P', P<2> in a main circuit C. By this arrangement a unidirectional current is obtained in a local circuit D connected between the secondaries, as shown, when an alternating-current passes in the main circuit or when direct-current changes in value in either direction. The coils P<1>, <p2> and S', S<2> are differentially wound in respect of one another and the secondaries are shunted by resistors L', L<2> so that, with normal flow through the main circuit, no current is induced in the local circuit. Instead of using two transformers, a single transformer with two magnetic circuits and a constant magnetizing winding on the middle limb M may be used, as shown in Fig. 7. The arrangement is particularly applicable to the tripping circuit of a high-speed circuitbreaker of the type described in Specification 125,279 in which the contact-member 13, Fig. 8, is held in the closed position by the electromagnet 15 energized constantly by direct-current in the coil 18 until the electromagnet is de-energized by direct current in the release coil 19. In the arrangement shown in Fig. 8, the circuitbreaker controls a circuit C carrying A.C. or D.C. in which the direction of current is liable to vary, as in regenerative D.C. traction systems. The operation of this circuit-breaker is described in Specification 187,993. As shown, the separate constant magnetizing coils M1, M2 are employed excited from the separate D.C. source c. In order to deal also with slowly-rising increases of current the magnetizing windings, which are shunted by resistances 20, 21 in order that no current shall flow in the tripping circuit in normal conditions, are shunted through a relay 22 and with slowly rising current the circulating current in this relay becomes sufficient to operate it and so break the main holding winding 18. The closure of the circuit-breaker is effected by the electromagnet 16 energized through pressbutton control 23 and through a resistance 25 and relay 24 to maintain the magnetic member 17<a> in attracted position during closure, as described in Specification 227,118. An arrangement employing reactances instead of transformers, and the application of a three-phase circuitbreaker are described also.
