Title: Alternating current control system
IPC: H03K19/082
Filed: 1972-04-06
Abstract: 1355014 Transistor A.C. logic circuits LA SALLE MACHINE TOOL Inc 6 April 1972 [14 July 1971] 15992/72 Heading H3T In an A.C. logic system, a device such as T44 conducts to charge C54 when the voltage across a resistor 28 falls to a predetermined level at which base current can flow, the predetermined level only being achieved when a given logic relationship exists between the A.C. input signals on lines 22, 24, 26. Considering half cycles of the supply when L1 is lower than L2, closure of any of switches 16, 18, 20 causes current through the associated resistor 30, 33, 35 to be diverted from the corresponding diode 34, 38, 42 and R28, to the corresponding diode 32, 36, 40. Only when all are closed does the current in R28 fall far enough to produce the predetermined voltage value to turn on T44. In another embodiment (Fig. 2, not shown), only one switch need close to turn on T44, this giving an OR function, instead of the AND of Fig. 1. T44 energizes the coil 52 of a relay whose contacts 12 trigger a triac device 14 to operate a load solenoid. Capacitor 54 maintains coil energization during the opposite half cycles of the supply. An autotransformer 11 supplies an intermediate voltage L3 for T44 emitter circuit.

Convention date, June 8, 1932. [Class 39 (i)] The cathode is attached to a holder which is adapted to be slipped into a Wehnelt cylinder to form a structural unit. A directly- or indirectly-heated cathode is secured within a copper bobbin 14, Fig. 2, which is housed within a Wehnelt cylinder, comprising cylinders 10, 11 connected together by the plate 27. The cylinder is closed by a mica plate 20, which is separated from a screening anode 18 by a distance piece 19 which is of smaller diameter and consists of insulating or conducting material; the piece 19 prevents the formation of a conducting bridge between the anode and the cylinder. The cylinder is supported through plates, e.g. plates 9, 20, by means of wires 3, which may be braced by means of transverse members and are fused into the pinch. A main anode 21, having a connecting lead 23, is mounted on insulating tubes which are slipped over the wires 3, and is spaced from the plate 20 and from an end member by insulating tubes 24. Semi-cylindrical hollow deflecting plates 4, 5, Fig. 4, formed of metal which has been annealed, may be secured to the wires 3 or to separate wires 2, through a ring- shaped member 6. The plate 4 is secured to the wires through a mica plate 7 and is connected to a lead 8, while the plate 5 is connected to the anode. A vaporizable material for activating the cathode and for gettering purposes is contained within a capsule 12 which communicates with the interior of the cylinder through a tube 13, and is so located that it can be heated independently of the heating of the electrodes during the degassing operation. The supporting wires may be welded to a metal tube which is fused into, or clamped around, the pinch. The cathode may be coated with barium oxide or may consist of tungsten oxide coated with barium. Controlling voltages may be applied to the anode 18, or, alternatively, a control grid may be provided within the vicinity of the cathode, and may be screened from the cylinder by means of a grid. A pointed cathode or one which comprises a zigzag filament may be used. Dimensions determining the spacing of the electrodes and values of the potentials thereon are given in the Specification.
