Title: Improvements in or relating to load distribution between power supplies to a network
IPC: H02J3/46
Filed: 1932-03-18
Abstract: 403,364. Speed governors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin). March 18, 1932, No. 8154. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 19, 1932]. [Class 57.] The frequency of the generators in each substation 2 supplying mains 1 is maintained constant by means of a differential gear 5, one side of which is driven by a standard clock 6 and the other side of which is driven by a synchronous motor 7 supplied from the mains, any difference between the speeds of the motor and clock causing one or the other of contacts 8 to close and so adjusting the governor setting of the prime movers driving the governors. To obtain an arbitrary adjustment of power distribution between the sub-stations each synchronous motor 7 is provided with a movable stator the position of which is adjusted by means of a reversible motor 12 controlled from a distant point F. Adjustment of the stator setting will cause the generators to function at a different normal governor setting and hence give a different power output. The stator may be manually adjusted, a scale indicating the load. In a modification a synchronous motor with a phase-shifter in the supply leads may be used. The clocks 6 in the different substations may be synchronised once or twice daily with a standard.

Abstract: 389,992. Vaporizers. SMYTH, E. L., 166, Lisburn Road, Belfast. March 29, 1932, No. 8976. [Class 7 (iii).] Combustible mixture from a carburetter enters an exhaust-heated chamber 1 at 4 and passes over vanes 3 so that unvaporized fuel can fall on a heated surface 2. The space between the vanes 3 and the base 2 increases in the direction of mixture flow. A plate 3d directs the rich mixture formed at the base of the chamber into the main stream and to keep the chamber at the required temperature the sides and the top are provided with heatresisting material 6. The vanes may be formed separately, or they may be pressed from a steel louvred plate. Each vane can be adjusted independently or the angularity of all the vanes may be determined by a common controlling rod which may be moved in unison with the throttle valve. To vary the distance of the vanes from the base of the chamber, the vanes may be connected together by side cheeks 3b hinged to the base of the chamber at 3c. In a modified construction, the top and sides of the chamber are formed separately from the heated base and insulated joints minimize the heat transfer. In a further construction shown in Fig. 4a, the chamber is a hot spot formed by an opening 11a in an inlet manifold 11 which is separated from the heated surface 10 by insulating gaskets 12 ; a grid of vanes 13 lies over the surface 10.
