Abstract: 24,776. Marks, E. C. R., [Landers, Frary, & Clark]. April 27. Urns and infusing-machines. - A special electric heater may be applied in an apparatus for making infusions, in which the top plate A of the heater heats a small boiling-chamber, which may be integral with it, and the peripheral flange F communicates heat to a flange on the main receptacle of the apparatus. Water passes from the receptacle to the boiling- chamber by a valve, and, when boiling, is projected on to a perforated cup containing the infusing substance. The base encloses a dead air-space surrounding the heater. The heater comprises a resistance. C held between a top plate A and a flanged plate G, the latter conducting heat to the ' flange F on the bottom plate B, spaced from the plate G by projections H, or otherwise thermally insulated from it.

Abstract: 25,207. Ateliers de Constructions Electriques du Nord et de l'Est. Nov. 8, 1911, [Convention date]. Field-magnets; auxiliary protective devices.- To reduce the strength of the momentary shortcircuit current of an alternator, an additional inductance is arranged in the direct - current exciting circuit of the machine, or the inductive effect is produced by the action of a subsidiary branch magnetic circuit situated on the field magnet. The Figure shows such a branch magnetic circuit comprising a disk E and yoke F of iron which are linked with the end portions B of the rotor exciting winding. The binding- ring G is preferably of non-magnetic material. The bars of the damping-winding used on the rotor are caused to project beyond the ends of the core A and through the disks E, the endconnexions being arranged beyond these disks. The exciting-windings may be connected to form damping-circuits by joining equipotential points by conductors which are linked with the branch magnetic circuits.

In the machine shown in Fig. 1, the windings on the stator s are so arranged that projecting iron parts form alternately north and south poles and no windings are provided on the rotor r. A single valve may be arranged in parallel with each winding, or four valves may be used as shown in Fig. 4, the winding being shortcircuited when all four valves are closed, and placed in circuit again when a pair of valves is opened, this being effected when the current is changing sign. To minimize energy losses due to inaccuracies in timing the operation of the valves, the reactance voltages in the windings may be compensated by means of a counter electromotive force, which may be obtained by arranging transformers in series with the windings. Auxiliary excitation windings may be provided in parallel with the windings shown in Fig. 1, the auxiliary windings being supplied with surging current from a separate machine through a condenser and an inductance, as shown in Fig. 5. The auxiliary surging current is arranged to be at a maximum when the valves are opened or closed, its direction being such as to assist the main current on closing the valves, and to oppose the main current on opening the valves. For igniting the valves, high-frequency current of adjustable phase may be used, the ignition being effected by the halfwaves obtained in a rectifier. Direct current or low-frequency alternating current may be superposed upon the high-frequency currents in the valves to compensate for losses of energy in working. An arrangement for obtaining highfrequency currents from accumulators acting in conjunction with controlled electric valves and an oscillating circuit is shown in Fig. 9.
