Abstract

246,996. Davis, N. R.., and Metropotitan-Vickers Electrical Co., Ltd. Jan. 21, 1925. Vacuum apparatus, arrangements of.-Two sets of thermionic or mercury vapour rectifiers 2, 3, 4, and 5, 6, 7, Fig. 2, are so connected to a polyphase alternating current supply, namely the star-connected secondary 1 of a transformer, that at any instant the rectifier current passes through a rectifier associated with one of the phases and return through a rectifier associated with a different phase. The anodes of the rectifiers 2, 3, 4 and the cathode of the rectifiers 5, 6, 7 are respectively connected to the terminals 8 and 10 of the load 9. The transformer may have a number of similar secondary windings 1<a>, 1<d>, Fig. 4, the load 9 being connected between the star points of the windings 1<a>, 1<d>, the anodes of the valves associated with the windings 1<a>, 1<c>, being connected respectively with the cathode of the valves associated with the windings 1<b> 1<a>, and the star points of the windings 1<b>, 1<c> being connected together. In this case the secondary windings may be phase-displaced with respect to one another. The individual rectifiers may be replaced by polyphase rectifiers, some having a single anode and a number of cathodes and others having a number of anodes and a single cathode.
