Patent GB-660794-A (GB)
Title: Improvements in or relating to circuit-arrangements comprising a combination of at least two relays
IPC: H04J3/04
Filed: 1948-04-16
Abstract: 660,794. Electron multipliers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 16, 1948 [April 21, 1947], No. 10635/48. Class 39 (i). [Also in Group XL (c)] A thermionic valve operates as a relay by causing the electron stream from a cathode which is controlled by a control electrode to strike a secondary emitting electrode, the electron stream from which flows to the main anode and so closes a switch path between the anode and auxiliary cathode which may be used to switch speech circuits in an automatic telephone exchange system. Fig. 3 shows two such relays I, II connected in series, the grid-shaped electrodes 9, 10 being at such a potential that they collect a substantial portion of the electron flow from the auxiliary cathode, thus enabling a large number of relays to be connected in series without large voltage drops being produced at successive auxiliary cathodes due to the current flow through the associated potentiometers. Fig. 4 shows a modification in which relay III includes a pair of electrodes 15, 16 which deflect the cathode current beam towards the auxiliary cathode HK and prevent its falling directly on the anode. Fig. 6 shows the electrode disposition of a change-over relay. The electrons from cathode 28 are formed into a beam and enter the space between deflection plates 29 which are slightly conical and are biassed so that the beam is deflected and passes via a grid 31 to auxiliary cathode 32, the associated switch path of which includes anode 33. The cathode-ray tube may be caused to operate as a change-over relay by deflecting the beam to the left and completing the switch path between the left hand cathode and auxiliary anode. The electron stream is shaped into a flat beam as shown at 71 in Fig. 13 so that the change-over point of the relay is clearly defined. A number of relays may be connected in parallel, Fig. 7 (not shown). The auxiliary cathode of a relay may be connected to the anode of a second relay via a resistancecapacity time delay network (see Group XL (c)). Fig. 12 shows a modification in which a collecting electrode 70 is situated in the path of the beam of relay 63 the voltage change at point 72 when the electron stream is incident on electrode 70 in association with the delay network 67, 68 applied to the deflecting plate 62 damps the movement of the beam so that it first is deflected rapidly and then more slowly as it reaches its equilibrium position.
