Figure 10 is a sectional View along the line 8-8 in Figure 5 to show a modified arrange-1 ment of the envelope.
To illustrate my invention, I have shown on the drawing, discharge devices ll comprising envelope means preferably formed of translucent material, such as glass, the envelope means being formed to provide a sealed container for a gaseous medium adapted to be energized to initiate elec tron flow therein, the device having electrodes whereby the gaseous medium may be excited.
The envelope may be formed in a variety of 55 ways and preferably comprises a sealed tubular element of glass defining an elongated channel in which the electrical discharges occur between the electrodes, which are arranged in spaced apart position on the channel. The envelope may be formed as a straight tubular element sealed at its opposite ends, preferably, however, the envelope is arranged so that the gas sealed discharge channel therein has a U-shaped portion or portions. To this end, the envelope may comprise an elongated tubular element bent intermediate its ends to the desired configuration. I prefer, however, to form the envelope of a suitable length of preferably glass tubing 13 having integral portions forming a partition 15 dividing the bore of the tube into a plurality of parallel and adjacently extending channels l1. In the embodiment illustrated in Figures 1, 2, and 3, the partition means l5 divides the bore of the tube l3 into two channels IT, while in the embodiments shown in Figures 4 through 9, the partition means 15 forms more than two channels in the envelope. The partitioned tube l3 may be made in any suitable way as by inserting a partition in a tubular member and fusing the side edges of the partition to the wall of the tube, or by fusing two tubes together laterally while plastic but I prefer to form the partition as a unitary integral structure of the envelope substantially as taught in my United States Letters Patent No. 1,904,348, issued April 18, 1933.
The devices shown in Figures 1 and 2 of the drawing are made from a suitable length of partitioned tubing, which is provided at one end with a dome l9, which seals the end of the tube and interconnects the ends of the channel portions IT. The lower end of each channel I! is provided with an electrode of suitable form and is sealed in any suitable or preferred manner, the electrodes having connections extending out through the sealed ends of the channel to permit connection thereof in an external electrical circult.
Rectifiers, embodying my present invention, comprise at least one cathode electrode 2| and a plurality of anode electrodes 23. The cathode electrode may be of any suitable form and construction and preferably comprises a filament whereby the same may be energized from an external source in order to promote electron emission at the cathode electrode. It is, however, within the contemplation of my invention to utilize other than an artificially excited cathode electrode. In the form shown in Figure 1, the cathode electrode is carried in the dome I9 opposite the end of the partition IS, an anode electrode 23 being disposed in, the remote end of each of the channel legs ll. In the form shown in Figure 2, the cathode electrode is disposed in the remote end of one of the legs H, the anode electrodes being disposed in the remote end of the other leg.
The device shown in Figure 4 of the drawing is made from a suitable length of partitioned tubing, in which the partition is arranged to form four channels IT., The tubing is provided at one end with a dome 19, which seals the end of the tube, the portions 25 of the partition being extended into the dome and sealed thereto so that the channels are inter-connected in pairs within the dome. The opposite end of one leg of each pair of inter-connected channels is sealed and provided with an anode electrode 23. The partition means, at the end of the tube opposite from the dome, is cut away as at 21 between the remaining legs of each inter-connected pair and a cathode electrode 2| is disposed in said cut away portion so that a serpentine discharge path having U-shaped portions is provided between the cathode electrode and each of the anode electrodes. Obviously, the serpentine path may be duplicated by suitably configuring a suitable length of tubing having a single channel.
The devices illustrated in Figures 2 and 4 facilitate the making of connections between the electrodes 2| and 23 and an external electrical network, with which the device is connected for operation, since all the electrodes are disposed at one end of the envelope II. I prefer also to assemble a base 29, preferably comprising a cupshaped element adapted to receive the electrodecarrying end of the envelope and having terminal' means 3| and 33 by which the electrodes 2| and 23 respectively may be connected in the external electrical network, the electrodes, of course, being electrically connected with the terminals. The end of the envelope may be secured at the support 29 in any suitable fashion as by pouring a thermo-plastic insulating compound into the cup-shaped element 29 after the end of the envelope has been inserted and electrical connections made between the electrodes and the terminals.
Rectifiers, embodying my invention, may be operated by connecting the anode electrodes 23 in an alternating current network comprising in the illustrated embodiment, a transformer 35, the primary winding of which is connected with a suitable source of alternating current power and the secondary winding of which is connected with the anode electrodes. livered in a circuit extending between the oathode 2l and the mid-portion of the secondary winding of the transformer 35, a choke coil 31 being preferably arranged in the direct current :35 Direct current will be decircuit to regulate current flow therein and subdue current fluctuations. The cathode electrode 2|, if desired, may be electrically energized by means of a circuit 39, the electrode being connected in the circuit by means of the terminals 3! carried by the base 29.
In the embodiment shown in Figure 5 of the drawing, I have illustrated one form of threephase rectifier. In this form, the envelope is made from a suitable length of partitioned tubing in which the partition defines four channels.
One end of the tube is provided with a dome 13 arranged to seal the end of the tube and to place all of the channels in communication with each other. sealed and one channel is provided with a cathode electrode 2|. The ends of the remaining channels are each provided with an anode electrode 23. I may form the envelope with the channel containing the cathode electrode 2| surrounded or encircled by the remaining anode channels as shown in Figure 10.
It is within the contemplation of my present invention to provide a multi-phase rectifier, in
which the envelope has only two channels as shown in Figure 2 of the drawing by simply arranging one or more additional anode electrodes The opposite ends of each channel are The multi-phase rectifier may be The multi-phase rectifier may be oper ated by connecting the anode electrodes in a three-phase alternating current system, which, in the illustrated embodiment, comprises a transformer, the several phases of the secondary winding of which are arranged in star conneotion, the direct current circuit extending from the neutral point of the star-connected secondary and the cathode electrode 2!. Suitable means, of course, are provided for energizing the cathode electrode if an artificially excited cathode is used as is the case in the illustrated embodiment.
It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description, and it is obvious that numerous changes may be made in the form, construction, and arrangement of the several parts without departing from the spirit or scope of my invention or sacrificing any of its attendant advantages, the forms hereinbefore described comprising preferred embodiments for the purpose of illustrating the invention.
