Title: An improved device for compensating tension in control cables
IPC: B64C13/30
Filed: 1943-09-22
Abstract: 570,015. Cable tensioning. GENERAL AIRCRAFT, Ltd., and LEATHER, G. B. Sept. 22, 1943, No. 15569. [Class 108 (iii)] A link interposed in a cable for compensating changes of tension comprises a cylinder 4 attached by a fork 8 to one length of cable and a piston 10 and rod 12 attached by a fork 16 to the other length of cable. A spring 18 interposed between the piston 10 and the cylinder head 14 imparts the requisite tension to the cable and the adjustment of the cable to the desired initial tension is facilitated by inserting a selected semicircular spacer 42 between the head 14 and a shoulder 44 on the fork 16. The spacers are of different lengths, and the cable tension is increased till the spacer drops off. To prevent too ready compression of the spring 18 when an operating load is applied to the cable, a liquid contained in the cylinder 4 is made to pass through a bleed valve orifice 22 when extension takes place, the valve 20 readily opening against a spring 24 when the load is lessened and compression of the link takes place. A spring-pressed piston 32 moving in the hollow piston-rod 12, or otherwise located, is open at one side to the atmosphere and on the other has liquid communicating through a passage 38 with the further end of cylinder 4. This compensates for the inequality effect produced by the effective area of the piston 10 being not the same on each side.

Title: Improvements in or relating to electric signalling systems suitable for use in radio navigation systems
IPC: H03K3/66
Filed: 1935-05-31
Abstract: 457,771. Valve generating circuits; directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and CLOUGH, N. H., Axbrindon, Hill Road, Brentwood, Essex. May 31, 1935, No. 15927. [Class 40 (v)] An automatic signal-generator, particularly suitable for keying the overlapping or interlocking radio-beams used for navigation purposes, or for controlling road-traffic signs, comprises two cross-coupled valves 1, 2 arranged to have a very rapid change-over between two definite states of equilibrium, one having a different duration from the other. One state, for instance, is used to modulate a radio-beam with a morse " dot" and the other with a Morse " dash." The duration for the valve 1 is determined by the charging rate of the condenser 21 and resistance 19, and that for the valve 2 by condenser 22 and resistance 20. At a certain voltage the condenser 21 is discharged through a Neon lamp 23 which accelerates the changeover by applying a sharp pulse to the grid 10 of valve 1, whereupon the valve 2 comes into action until the discharge device 24 breaks down, and the cycle is repeated indefinitely. The changes of potential set up in the anode circuits of the valves 1, 2, are applied successively and in push-pull to two pentode valves which are used to modulate two overlapping radio beams. If gas-filled valves are used, the two anodes are connected by a condenser 31. A self-starting resistancecapacity combination 33, 32 and discharge device 34 may be inserted, as shown, to initiate operations. A pair of auxiliary valves may also be shunted across the two timing condensers 21, 22 and are automatically "triggered" to accelerate their discharge.
