Title: Improvements in or relating to Arrangements for Equalizing and Compensating the Loads on the Phases of Polyphase Current Systems.
Filed: 1907-09-10
Granted: 1908-09-10
Abstract: 20,203. Siemens Bros. Dynamo Works, [Siemens-Schuckertwerke Ges.]. Sept. 10. Distributing.-For the purpose of equalizing the loading, or compensating for unequal loading on the respective phases of polyphase systems, separate single-phase machines are included in each phase to give the necessary buffering action. The respective single-phase machines may be provided with flywheels, and may act as independent units, or may be mechanically coupled, in which case the machine of the overloaded phase is driven as a generator by the others as motors. Fig. 1 shows a three-phase system having independent fly-wheel single-phase machines b, b<1>, b<2>, the field-windings w, w<1>, w<2> of which are supplied from separate generators g, g<1>, g<2> on the shaft of a synchronous motor g<3>. The difference of potential of each buffer machine may be regulated according to the load on its phase. Mechanical coupling of the machines serves to equalize the load on the phases. By the use of the Scott system of transformers or other means for converting the number of phases of a system, fewer single-phase machines are rendered necessary.

Granted: 1909-04-01
Abstract: 7409. Rorke, T. J., and Rorke, E. April 3. Switches.-In mercury switches, particularly for controlling remote circuits, " break " is effected by tilting a container to rupture a column of mercury, " make being effected by tilting the container to re-unite the column. A block a<1> of clay &c. mounted on pivots a<2> is formed with a U-channel a covered by a glass plate b. The legs a of the channel are each provided with a contact-plate b<3>, connected by a lead b<4> to a terminal b<5> of the main circuit. In the position shown, the mercury b<x> forms a column connecting the plates b<3> ; but, when the container is tilted, the mercury separates into two columns and breaks the circuit. To lessen sparking at the place where the mercury column is ruptured, there may be a series of passages communicating with an outer U-channel, so that the mercury takes a number of paths, thereby increasing the number of " breaks." The channel may be replaced by a U or a V tube, or the channel may be continuous, the apparatus being then used as a change-over switch. The block a' is preferably tilted by electro-magnetic means comprising two solenoids provided with cores c<2> connected to the block by chains c<3>. The solenoids are in a battery circuit which is connected to a mercury tube d mounted in the block and arranged to cut out the battery circuit immediately the block is tilted.

Title: Improvements in or relating to Condensers for Steam Driven Vehicles.
Inventor: BALCKE HANS
Filed: 1908-06-01
Granted: 1909-04-15
Abstract: 11,886. Balcke, H. June 1. Locomotives ; locomotive railway and tramway vehicles.-A condensing - apparatus is described for use on steam-driven vehicles, the condensation being effected exclusively by a cooling liquid, which in turn is cooled exclusively by the air current produced by the movement of the vehicle. Figs. 1 and 2 are elevations. Fig. 4 is a detail view of the cooling-tubes and their connexions. Exhaust steam from the locomotive cylinders is admitted to the. tank g and thence to the ribbed pipes a where it is condensed. The condensed steam collects in both tanks g, l whence it is removed by the pump c. The air is drawn from the tank l by a rotary air-pump band discharged into a funnel h. The water used is drawn from the tender by the pipe i, and returned through the grease filters m and the pipe k. The pumps b, c are driven by steam turbines e,f respectively. The turbine f also drives a fan d for the production of a furnace blast. The condensing- apparatus is shown in Fig. 4, in which the tubes are double. The inner tube receives the steam, and the outer one holds circulating water which is cooled by the motion through the air. This acts as a cold reservoir or "accumulator" and ensures efficient condensation when starting. The water pipes communicate at the ends as shown, and there is also communication between the two tanks g, l by pipes n, n<1>. The steam at starting is admitted to the tank g and thence to the copper pipes. The water in the external pipes is heated, rises, is cooled by air and descends on the other side, the circuit being completed by the pipe n.

Granted: 1908-12-17
Abstract: 17,581. Krupp, Akt-Ges., Germaniawerft, F. Nov. 6, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Exhaust gases, discharging under water; submarine vessels.-To prevent the track of submarine boats from being discerned, the exhaust gases are conducted away from the boat by trailing pipes, which do not rise to the surface, so that the gases reach the surface at some distance from the boat. The pipes may be directly connected to the exhaust pipes or to an intermediate reservoir into which the exhaust pipes open. If a number of pipes are used they are made in different lengths, so that if the gases are allowed to issue from all the pipes simultaneously the impression will be given that a number of boats are present. Cut-off devices may be fitted in the pipes so that the gases issue alternately by pipes of different lengths, and non-return valves are fitted to prevent the water from entering the pipes.
