Title: Improvements in or relating to mechanical remote control telegraph and like systems
Inventor: BREWERTON ARTHUR ERNEST
IPC: G08B9/08
Filed: 1955-08-19
Abstract: 827,594. Order-telegraph signalling apparatus. CHADBURNS (LIVERPOOL) Ltd. Aug. 20, 1956 [Aug. 19, 1955], No. 23901/55. Class 118(2). A mechanical telegraph comprises two movable or rotatable members (e.g. two pulley wheels), one in a transmitting instrument and one in a remotely located receiving instrument with a cable or like connection between the members for the operation of one by the other, and elastic means, such as springs acting respectively on the members in opposite directions. As shown in Fig. 1 the transmitting pulley 11 operated by a handle 14 and connected by a cable 16 to a receiver pulley 12 carrying a pointer 15 has a biasing spring 19, whilst a spring 17 is connected to the pulley 12. The springs are of considerable length and the arrangement is such that the springs counterbalance when the instruments are in mid position. The extreme positions of the handle 14 and pointer 15 are determined by stops 20, 21 and 22, 23. In the two-way arrangement, Fig. 2, having transmitting and receiving pulleys 11, 12 on shafts 24 at the separate locations and connected by cables 16b, the springs 17, 19 are simulated by springs of the type used in gramophone motors connected to a hub portion formed on the pulley 12 and to a sleeve extension on the pulley 11. The cable portions 16a on the pulleys 11, 12 are formed with enlarged eye portions 16c engaging stop plates 16d and connected to hooks on the main cable portion 16b. For the installation of the system a short length of cable with ferrule 16c is attached to the pulley 12, and stops 20, 21 are removed so that the pulley 11 can be rotated to wind the spring 17, 19 but not to its full extent. After the stops have been replaced, the cable portion 16a is fixed to the pulley 11. The pulley 12 is then rotated to a limited extent and the end 16c connected to a hook in the end of the cable 16b which at the remote end is attached to the short cable 16a associated with the pulley 11 of that instrument which has been similarly adjusted. The cable 16a of the pulley 12 of this instrument is likewise connected by cable 16b to the cable portion 16a of the pulley 11 at the other station. The transmitting positions of the handle are accurately located by a star wheel mounted on the transmitting shaft and engaged by a detent roller carried on a spring-biased lever. Switching means may be provided to sound an alarm or illuminate a visual signal which remains in operation until a reply signal has been received and the two instruments are in corresponding operational positions.

Title: Improvements in or relating to electrical signalling systems
IPC: B61L25/04
Filed: 1935-08-27
Abstract: 461,982. Electric signalling systems. ASSOCIATED ELECTRIC LABORATORIES, Inc. Aug. 27, 1935, No. 23939. Convention date, Sept. 27, 1934. [Class 40 (i)] In a system in which a number of devices connected in series along a line are operated simultaneously from a transmitting station, an indication is given at the transmitting station over a special checking line if the receiving device at any station is off-normal. As shown number drums 84, 72, 62 and 8 at stations A, B, C and the transmitting station respectively are set simultaneously whilst further drums at the same stations are set for other digits. Each drum carries a cam which closes series connected cam contacts 13, 63, 73, 83 in the normal position of the drum so that relay 145 is energized when all the drums are normal and lamp 7 is lit. Similar circuits are provided for the other drums. To set the drums 8, 84, 72, 62 one of the digit keys 1-0 is depressed so that two of the relays 110-130 are energized and lock to mark a contact on switch S. Relays 105, 100 energize to connect the key-set to the next digit relay group. Magnet 135 is energized to close circuit 37 and magnet 80 pulls up. Magnets 70, 60 and 5 energize in turn over obvious circuits and magnet 5 closes circuit 38 so that relay 140 energizes to open the circuit of magnet 135 and magnets 80, 70, 60 and 5 release in turn. Magnet 135 steps wiper S one step and magnets 80, 70, 60 and 5 respectively step drums 84, 72, 62 and 8 one step. The chain circuit 31-36 is broken and lamp 7 goes out. This cycle is repeated until wiper 150 finds the contact from which earth has been removed by both the operated relays. To reset the apparatus key R is depressed so that magnet 20 energises and locks to earth at 26. All the energized relays of the relay groups release and switch S is stepped as described above until it and all the associated number drums are normal. Relay 145 is re-energized to relight lamp 7 and when the relays corresponding to 145 for all the number drums have energized, a chain circuit from 147 over 39<1> and 40 is closed to reenergize relay 25 so that relay 20 is released.

Abstract: 449,219. Valve circuits for wireless reception. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Aug. 29, 1935, No. 24166. Convention date, Aug. 30, 1934. [Class 40 (v)] The amplification of an alternating current signal receiver, is automatically adjusted at the commencement of a transmission from a given maximum value to a predetermined minimum value, after which it remains constant. As shown, a carrier wave receiver comprises a detector 1, Fig. 1, and amplifier 2, the amplification of the former being regulated by a rotary potentiometer R, the moving contact dr1 of which is attached to the rotary member of a step-by-step selector Dr, Fig. 2. A relay T in the output of the amplifier 2 responds to a signal output of over a predetermined amplitude and energizes relay V through contact t2 also preparing the circuit of magnet Dr at t1. When the subscriber releases the hook switch g the relay B is energized to move contact b1 thus energizing magnet Dr. The contact dr1 is moved one step and the relay T de-energized by the opening of contact dra1 to introduce a resistance into its circuit. The magnet Dr is thus de-energized and the cycle repeated until the contact dr1 has moved to such a position that the relay T is no longer energized by the signal. In this event the time-delayed relay V falls back closing contact v2 to energize relay N which locks up over contact n2 and breaks the circuit of magnet Dr at contact n1. If the selector Dr runs to its last step relay N is energized through contact drn. At the end of the transmission the relay B is de-energized by the hook switch g, the relay V is de-energized at b2 and the relay N at b1 which closes the circuit of the selector release magnet through contacts dvw, dvwo.
