Abstract

648,272. Discharge apparatus. KAY, J. M., and McLEOD, T. S. Aug. 25, 1947, No. 23470. [Class 39 (i)] In an electrical generating apparatus of the kind in which a stream of working material such as mercury vapour is passed through a chamber transversely of a magnetic or electrostatic field, and electrodes are located in the chamber for connection to a load circuit, electrons are introduced into the stream by means of an arc. Mercury vapour from a boiler 1, Fig. 1, passes through a nozzle 3 into an expansion chamber 4 in which the heat energy of the stream is converted into electrical energy by the action of the injected electrons in slowing down the stream. The mercury then passes to a condenser 5 from which it is returned to the boiler 1 by a pump 7. The chamber 4 has one transverse dimension much smaller than its other transverse dimension. A magnetic field is produced across the narrow dimension. The wider dimension is bounded by the electrodes 13, 14 between which the external load is connected. In the bottom electrode 14 are located a number of mercury pools 16, each constituting with an adjacent electrode a mercury arc device for injecting electrons into the mercury vapour stream. In another embodiment, the magnetic field is dispensed with and an electrostatic field is established between a number of mercury pools 16, Fig. 4, and an electrode 19 disposed at the upstream end of the chamber 4. Arcs are established between the pools 16 and adjacent electrodes 17. The chamber 4 may be of square section. The load circuit 15 is connected between the electrode 19 and a grid 20 located at the point where the chamber 4 joins the condenser. Mercury particles of the stream are ionized; electrons are extracted by the electrode 19, whilst positive ions due to repulsion from the positive charge built up on the grid 20 act to slow down the mercury vapour stream. According to the Provisional Specification an inert gas such as argon or krypton may be used instead of mercury vapour.
