Abstract: 248,381. British Thomson-Houston Co., Ltd., (Assignees of Hamilton, W. S. H.). Feb. 25, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Charging batteries.-Where, as on electric locomotives, there is a high tension supply 11, feeding translators, such as blowers 13, 14 and air-compressors 15, 16, but it is desired to have the lighting system 27 and control 28 supplied at a low voltage, charging of the battery 10, which is one of the sources for the low voltage supply 26, is controlled according both to its charging current, and its state of charge. If it is not fully charged the indicator 31 of an ampÞre hour meter or the like is not in contact-closing position, so that if the charging current is excessive or not charging still takes place, and, even if it is fully charged, with normal supply a steady slight overcharge is permissible. If, however, the indicator 31 completes its contacts, showing that the battery is fully charged, and at the same time, the charging current is sufficient to operate the relay 23, coil 22 is energized and a resister 21 is thrown in, in shunt to the battery to reduce the current through it.

Abstract: 895,380. Liquid fuel burners. BABCOCK & WILCOX CO. Feb. 21, 1961 [Feb. 24, 1960], No. 6328/61. Class 75(1) A liquid fuel burner comprises a cylindrical whirl chamber 37, Fig. 3, having axially spaced tangential fuel inlets 40 decreasing in size towards the discharge end of the whirl chamber, and a plunger 42, Fig. 5, adpated progressively to uncover the fuel inlets 40 and provided with apertures 42B in its end face for dischargingair into the whirl chamber 37. The plunger 42 is mounted on the end of a tube 41 extending through a fuel supply tube 28 and through an air chamber 45 in a housing 31 detachably clamped to a tubular distance piece 29 surrounding the fuel tube 28. Air is supplied to the chamber 45 by an air pipe 81 controlled by a solenoid valve 76 and enters the plunger tube 41 through radial holes therein. A coil spring 43 acting between the housing 31 and a collar on the outer end of the plunger tube 41 biases the plunger 42 away from the discharge end of the whirl chamber with all the fuel inlets 40 uncovered. The plunger is moved to reduce the fuel flow by a push rod 74 actuated by a handjack 90 or by an electric motor 73 mounted on a yoke 99 pivoted to the housing 31. A device responsive to steam pressure sends an impulse to a controller 71 which actuates the motor 73 to withdraw the push rod 74 to allow the burner to operate at full load. In response to a lower demand, the motor 73 advances the push rod to reduce the flow of oil into the whirl chamber. At a predetermined low load the controller 71 actuates a switch 75 which then opens the air valve 76 to supply air at a higher pressure than the fuel to the whirl chamber. Combustion air is controlled by an air register 19 comprising adjustable pivoted vanes 51 actuated in unison by gears 55 on the vanes meshing with a gear 57 on a sleeve 58 having a gear sector 59 meshing with a pinion 60 rotated by a crank shaft 61.
