Title: Improved automatic voltage regulator
IPC: H02P9/18
Filed: 1950-02-09
Abstract: 667,439. Differential switches. REED & CO., Ltd., A. E., and CATTELL, P. W. Feb. 9, 1950. No. 3401/50. Class 38 (v). [Also in Group XXXV] A differential switch controlling an automatic voltage regulator (see Group XXXV) consists of a pair of contacts 7, 8 mounted on arms secured to an insulated sleeve 14 on a shaft 5, rotated by a constant speed motor. The contacts are connected to slip rings 9, 10. A third contact 6 is mounted on an arm 3 secured to an insulated shaft 19, which is friction driven by a rotating shaft 4. When a speed differential exists between the sets of contacts, contact 6 engages with either contact 7 or contact 8 to operate the automatic control system.

Patent GB-539033-A (GB)
Title: Improvements in or relating to remote control arrangements, such as for radio transmitters
IPC: H04B1/16
Filed: 1940-02-23
Abstract: 539,033. Radio transmitting systems. STANDARD TELEPHONES & CABLES, Ltd., and BOWSHER, E. A. H., Feb. 23, 1940, No. 3435. [Class 40 (v)] [Also in Group XXXVIII] A radio transmitter is controlled for alternative telephony and telegraphy over a line L1, 2 from a remote control unit provided with a microphone T, telegraph key MSK and keys for setting up the alternative sending conditions. Currents of opposite polarities are fed alternatively to the line through relays at the transmitter end, and the connection in the loop of either one of two rectifiers MRA, MRB determines which polarity shall be effective. A resistance R allows the intensity of current to be varied. Current is normally fed through relays ST, P, and closure of start key STK completes the loop through rectifier MRA and resistance R to energize relay ST only, whereupon relay TR completes the low tension circuit of the radio transmitter. Actuation of key HPK short-circuits resistance R and allows the operation of P, which switches on the high tension at low power for telephony and closes the carrier control circuit. Relay PS energizes and alters the connections of ST, P to the line. When key HPK is restored, reversed current through relays K, T is connected momentarily to the line during the release time of PS, and if key KK, which shares the same knob with HPK, is actuated at the same time, the loop is completed through rectifier MRB and resistance R. Relay T energizes and connects up TA, which switches on the high tension at full power for telegraphy, operates TS and holds PS. Telegraph key MSK by short-circuiting resistance R controls relay K, which in turn controls the carrier control circuit. In a similar manner, when key KK is restored, normal current through ST, P is connected to the line during the release time of TS to test whether key HPK is actuated.

In the construction shown in Figs. 1 and 2, the units a, which may represent the bricks of a wall, are each formed as a trough in cross section, and are connected by steel spring clips d having curved or curled ends e which engage interior surfaces of adjacent units. The line joining the points of contact between the clip and the units passes be- . tween the areas over which the units are in contact so that tilting is prevented. Instead of being trough-shaped, the unit may have an undercut recess or recesses extending over part of its length only, and the sides of these recesses may be inclined so that the clips engage with a wedging action. The unit may also be surrounded by a band attached to it at two or more places, the spaces between the unit and the band admitting the limbs of a U-shaped clip. In another modification, each unit has a trough of dovetailed section, so that the units may act as the means of attachment instead of clips. Fig. 3 shows a series of hexagonal units assembled to form a built-up design. Each unit is provided with recesses h, the sides of which are grooved parallel with the faces of the unit and these grooves engage the ends e of the clips.

Abstract: 552,659. Colour television; cathode-ray tubes. HAZELTINE CORPORATION. March 27, 1942, No. 4105. Convention date, April 28, 1941. [Classes 39 (i) and 40 (iii)] A colour television signal-translating system comprises a cathoderay tube having a plurality of spaced targets associated with respective optical systems and cathode-ray beams, one for each colour, the cathode-ray beams being arranged to pass through a restricted region where a single set of beam-deflecting means are provided to cause the scanning action of all the beams. In the transmitter shown in Fig. 1, the picture 23 is imaged by three optical systems 22a, 22b, 22c with colour filters 24a, 24b, 24c on three spaced targets 21a, 21b, 21c in the cathode-ray tube 20, which also contains three separate cathodes 25a, 25b, 25c, three separate control grids 26a, 26b, 26c, first and second accelerating anodes 27, 28, and a common collector anode 29. The three beams cross each other in a restricted region where they are subjected to a single set of line and field scanning means of the electrostatic or magnetic type. The magnetic type is indicated on the Figure by the windings 32, 33 and 34, 35. The three spaced targets, which may be separate screens or parts of one screen, are connected to the output impedance 36, from which the signals are fed to an aerial system 14, 15 through the usual channel 11, 12, 13. The scanning windings are supplied from usual circuits 16, 17 connected to the synchronizing signal generator 18. The three cathoderay beams are triggered in succession by pulses 39a, 39b, 39c fed to the control grids 26a, 26b, 26c from relaxation oscillators 38a, 38b, 38c controlled by the synchronizing signal generator 18. These pulses 39a, 39b, 39c serve also to modulate supersonic oscillators 44a, 44b, 44c, the output of which is mixed with the audio frequency from a generator 43 and fed through a sound transmitter 40 to an aerial system 41, 42. The receiver, Fig. 2 (not shown), is similar to the transmitter, the supersonic signals being separated from the audiofrequency and then divided into its three constituents by means of tuned circuit to trigger the three cathode-ray beams in succession. Instead of transmitting supersonic signals for the keying of the successive cathode-ray beams of the receiver, this may be performed by the provision at the receiver of relaxation oscillators corresponding to the oscillators 38a, 38b, 38c of the transmitter. Instead of rendering each cathoderay beam operative in turn by means of the pulses 39a, 39b, 39c, the beams may be arranged to be normally operative and the pulses arranged to suppress in succession the unwanted beams.

Abstract: 1,197,112. Regulating. FORD MOTOR CO. Ltd. Jan. 27, 1968, No.4391/68. Heading F1B. An exhaust brake valve, of a compression ignition engine, operated through a solenoid 1, is controlled in response to engine or vehicle speed and to accelerator pedal position, the valve being closed if the accelerator pedal is released when the speed is above a predetermined value, the engine fuel supply being simultaneously cut off. The solenoid 1, which may control an air valve of a pneumatic operating system for the brake valve, is in series with a micro switch 7, operated by the accelerator pedal, and a speed responsive switch 3, 4 operated by a relay 5. A generator 11 produces a voltage at a frequency varying with engine or vehicle speed and a detector device in the relay 5 closes the switch 3, 4 relay a predetermined frequency is reached. If the accelerator pedal is released at high speed, switches 7, 3 and 4 are closed and solenoid 1 closes the brake valve and shuts off the fuel. When the speed drops below the predetermined valve, or the accelerator pedal is depressed, solenoid 1 is de-energized and the brake valve opened and fuel supply resumed.
