Title: Improvements in and relating to electronic valve devices
IPC: H01J25/78
Filed: 1946-08-01
Abstract: 625,271. Electron beam valves. METSON, G. H. Aug. 1, 1946, No. 22956. [Class 39 (i)] In a beam deflection tube the transit time of the electrons through the deflection plates is increased by using crossed magnetic and electric fields so that the electrons follow a cycloidal path from cathode .to anode. In Fig. 1 a steady magnetic field is applied in the direction shown. An electric field at right-angles to this is applied by two plates 12. Deflection plates 6 enable the beam to be deflected on to one of the anodes 8. The cathode is a copper cylinder coated with alkaline earth oxides and is supported from one of the plates 12, Fig. 5 (not shown). The anodes may be two plates separated by a narrow slot centrally placed with respect to the undeflected beam. In another form, Fig. 6, the electric field is established between a central wire 21 and a curved outer surface 22 coaxial with the wire ; a magnetic field is applied along the axis. 23 is the cathode, 24 the anodes, and 25 the deflection plates. In either embodiment small negative potentials may be applied to the deflection plates to assist focusing, or special focusing electrodes may be used. A grid electrode may be provided and may be adjacent to the anodes.

Title: Improvements in or relating to telephone repeaters or the like
IPC: H04L25/04
Filed: 1931-08-18
Abstract: 388,065. Two-way transmission. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. Aug. 18, 1931, No. 23281. Convention date, Sept. 2, 1930. [Class 40 (iv).] The alternate connection of the two paths of a repeater to the associated line circuits in accordance with the direction of speech is effected by differential relays 1, 2, controlled by voicecurrent relays 4<1>, 4, operated through additional amplifiers by incoming speech currents. The valves of the speech and control amplifiers are of the indirectly-heated-cathode type and normally receive a small heating current from battery A over resistances R, R1. When the junction with which the repeater is associated is taken into use for a call, the closure of a contact K, by a manual key or by plugging-in in the case of a manual exchange or automatically upon seizure of the junction in the case of an automatic exchange, operates relay 3 which by short-circuiting resistance R1 increases the heating current to its full value. Relay 3 also connects up anode battery B and supplies ground G to all the points marked on the Figure by ground within a circle. Differential relays 1, 2, 5, 6, 5<1>, 6<1> are then energized over both windings and do not operate. When speech arrives over line W, relay 4 vibrates its contacts, unbalancing relay 2 which connects up transmitting branch 8, 9 and disconnects receiving branch 8<1>, 9<1>, relay 6 which locks relays 1, 5<1>, 6<1>, in the receiving path against control by relay 4<1>, and relay 5 which short-circuits a third winding to maintain the connections during short pauses between words. A high-pass filter C, I, associated with relay 4<1> prevents operation of this relay by telegraphic frequencies in systems in which the line E between repeater points is used for telegraphy. The grids of the valves are supplied with positive bias from a battery D.

Title: Servo-motor
IPC: F03G7/06
Filed: 1971-04-19
Abstract: 1345322 Temperature-responsive actuators DANFOSS A S 19 April 1971 [18 March 1970] 23913/71 Heading F1S [Also in Divisions G1 and H1] During normal operation of the actuator, the piston 5 moves in and out of the cavity 2 depending on the volume of the expansible substance 3. This movement is transmitted to the lever 12 via a friction plate 13 on heating up of the expansible substance 3 by a resistor 4 the piston is pushed out of the cavity a short distance. This causes the lever 12 to rotate about its pivot 11 which in turn causes the contact 15a and the armature 18 to move away from their middle or equilibrium position. After moving a short distance the contact 15a moves away from the contact 15b and the power supply to the resistor is cut off. The expansible substance then begins to cool and the piston 5 is pushed back into the cavity 2. As the expansible substance contracts eventually the contact 15a is carried back into contact with the contact 15b and power is again supplied to the resistor 4. If the switch 27 is closed for a brief period the armature 18 moves up to the stop 29. This causes the friction plate to slide over a predetermined distance along the piston 5. In this position the switch 14 is closed. As a result of the heating, the piston 5 is pushed out of the cavity 2 until the armature has again reached its middle position thus the friction plate 13 has been displaced over a predetermined distance relative to the piston 5. A member that has to be controlled can be connected to the free end 9 of the piston.
