Title: Improvements in and relating to television systems
Inventor: ADORIAN PAUL
IPC: H04N7/167
Filed: 1953-02-27
Abstract: 749,627. Television. COMMUNICATIONS PATENTS, Ltd. March 29, 1954 [Feb. 27, 1953], No. 5584/53. Drawings to Specification. Class 40 (3). Satisfactory reception of a television transmission is restricted to privileged persons (e.g. subscribers to the organization controlling the system) by arranging that at the transmitter picture signals alternately modulate the vision carrier in a positive and negative sense, the alternations being controlled by a sub-sonic frequency signal which is radiated over the sound channel of the system and at subscriber receivers is employed to control the application of received vision signals alternately to the grid and cathode electrode of the picture reproducing tube so that a positive image is always reproduced irrespective of the type of modulation employed at the transmitter. The timing of the change of type of modulation may be determined automatically by predetermined changes in the characteristics of the picture being transmitted (e.g. mean brightness corresponding to the end of a picture sequence) and to improve the secrecy of the system the subsonic frequency may be changed occasionally and a corresponding modification made at co-operating receivers either manually (by means, of interchangeable plug-in elements) or automatically in response to a signal transmitted by the transmitter.

IPC: H03D7/10
Filed: 1925-03-05
Abstract: 252,789. Andrewes, H., and Dubilier Condenser Co., Ltd. March 5, 1925. Thermionic heterodyne receivers.-A frequencychanging arrangement for supersonic reception comprises one or more four-electrode valves wherein one of the grids is maintained at a positive high potential, and wherein a circuit tuned to the supersonic frequency is included in the anode circuit. The grid G<1> of the valve V2 is at the same potential as the plate, and is connected in parallel with the grid G1<SP>11> of a second valve VI. The valve V2 produces sustained oscillations of a frequency determined by the circuit L2, C2, and the corresponding voltage variations of the grid G' are communicated to the grid G1<SP>11> of the valve V1 from the tuned circuit L1, C1. The plate current of the valve V1 therefore comprises both the signal and locallygenerated oscillations, the resultant beat or intermediate frequency appearing in the tuned circuit L3, C3. The two tuning condensers C1, C2 may be of the straight-line type and be controlled by a common spindle; or the inductances L1, L2 may be mechanically-coupled variometers. The separate functions of the valves VI, V2 may be performed by a single four-electrode valve.

Patent GB-699685-A (GB)
Title: A new or improved telegraphic code translator
IPC: H03M7/40
Filed: 1950-03-13
Abstract: 699,685. Type-printing telegraphy. ELIASEN, E. A. B., and JENSEN, K. R. F. March 13, 1951 [March 13, 1950], No. 6273/50. Class 40 (iii). In an arrangement for producing signals in a code which utilizes case-shift signals, e.g. the Baudot or 5-unit code, from characters recorded in a code having no shift signals, e.g. the Cable or Wheatstone code, the signals in the " shift " code are produced by one or the other of two sets of operating elements whilst signals of characters in the same case are being translated, and on the occurrence of a character in a different case, the shift signal is produced by the active set of operating elements which then becomes inoperative and the signal in the shift code and subsequent character signals are produced by the previously inactive set of operating elements until the next character requiring a shift signal is encountered. Sensing members controlled by a tape perforated in Wheatstone morse actuate lugs 11 on notched discs 10 which control selector bars 15 associated with ten notched discs 16, arranged in two groups of five and selectively allowed to move by the action of springs. The bars 15 corresponding to letters and upper-case characters, such as figures &c., are disposed alternately and the operation of a bar 15 requiring a change of case moves a toothed disc 17 carrying an arm 171 closing pairs of contacts 173, 174 or 173, 175 energizing a magnet 40 or 41, Fig. 2, which reciprocates a slide member 18 having projections associated with ten members 160 ... 169 connected to the ten discs 16. When an operated bar 15 corresponds to a character in a different case from the preceding character, the group of discs 16 corresponding to the appropriate case shift character is free to rock to actuate the corresponding members 160 ... 169 and the rocking of the arm 171 energizes the magnet 40 or 41 to move the slide 18 so that the second group of the members 160 ... 169 is free and will be utilized to produce the five-unit signal representing the character or symbol. The movement of the member 171 also energizes a magnet 37 so that its armature 38 engaging a lug 60 on a cam-controlled bell-crank 53 suppresses the tape-feeding action and the bar 15 actuated by the Wheatstone code signal then co-operates with the freed discs 16 to transmit the appropriate five-unit signal. The members 160 ... 169 are released to their normal position after each signal transmission by a bail 33 operated by a cam on the main driving-shaft 21 which also drives a distributer 22 controlling the transmitting relay 23 in accordance with the impulses stored on condensers C1 ... C5 corresponding to the operated contacts 35 selectively closed by the members 160, 162 ... 168 or 161, 163 ... 169.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1930-02-25
Abstract: 355,780. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Feb. 25, 1930, No. 6276. Convention date, Feb. 28, 1929. [Class 40 (iv).] In systems in which different register - controllers are connectable to different subgroups of finders serving a common group of subscribers' lines, an allotting switch is started by a call and in successive positions starts finders (up to a predetermined number) belonging to different sub-groups. In each position the allotter may start one or more finders of a sub-group, or in each position it may start one finder in each of two sub-groups, finders of two different sub-groups being started in the next position. A finder is only started if it is connectable or preconnected to an idle registercontroller. The system may be of the kind in which each register-controller is common to a number of groups of subscribers' lines, e.g. each register-controller may be connectable to a finder in one sub-group of each group, or each register-controller may be connectable to two finders in each group and each finder to two register-controllers. The finders are of the rotary-and-radial type described in Specification 176,065, [Class 40 (iv), Telephones &c.]. Call-finder circuits. When a subscriber calls, his line relay LR and the sub-group and group starting relays LRG, SSR2 are operated and circuits are closed for relays RS8 to start all idle call finders corresponding to the position in which the allotting switch finds itself. Relays RS8 energize relays RS5 provided the register-controllers to which the link circuits in question have access are idle. RS5 energizes the rotary magnet CVS of its finder. Meanwhile the allotting switch SS which is started up by SSR2 as soon as the subscriber calls, goes on allotting new finders until there is a predetermined number of relays RS8 in parallel, in series with SSR4 (i.e. a predetermined number of finders hunting) whereupon the latter relay stops the allotter. When a finder reaches the calling radial row, RS1 pulls up over wiper d and locks itself, shunting out LRG which stops SS and removing the rotary marking. RS1 also drives on the sequence switch SOS and shunts out RS5 by RS4, This action also shunts the relays RS5 of all other finders using the same register-controller and so prevents their being started. RS1 falls as soon as SOS goes on but RS4 is held independently and when the sequence switch reaches 3 the radial magnet CRS drives the wipers until RS1 is again energized, this time in series with the cut-off relay BR. RS1 also drives the sequence switch to position 4 in which RS9 associates the link circuit with the registercontroller. RR4 responds to dialled impulses and the selector is started by a circuit over La and sends back impulses over Lb to the outstepping relay RR7. When the register-controller has finished it drives SOS to the talking position 6.

Abstract: 590,530. Valve relay circuits. BUDD MANUFACTURING CO., E. G. March 13, 1945; No. 6326. Convention date, Jan. 4, 1944. [Class 40 (v)] In an automatically repeating timing device a single relay is operated to connect one or other of two load circuits to A.C. mains, timing means determining the period when current flows through the relay. Upon closing the switches 57, 58 in succession, the thyratron 31 fires, causing retay 20 to operate and load circuit 15 to be completed. During the negative half - cycle when thyratron 31 is extinguished, the relay remains operated due to its shaded pole construction and capacitor 62 is partially charged over diode 36 and resistor 50. The capacitor 62 continues to charge during each negative half cycle until the outer grid becomes sufficiently negative for the thyratron 31 not to refire in a positive half-cycle. The relay 20 releases, completing the load circuit 18 and a discharge circuit for capacitor 62 over resistors 75, the control grid being connected to prevent thyratron 31 refiring immediately. The capacitor 65 is discharged until the thyratron 31 refires when the cycle recommences. The banks of resistors 50, 75 are included in the charge and discharge paths of capacitor 62 to permit the selection of suitable periods of operation.
