Title: Improvements in or relating to thermally actuated servo-mechanisms
IPC: G05D23/19
Filed: 1960-07-28
Abstract: 952,989. Motors operated by expansion of liquids. CRANE CO. July 28, 1960 [Sept. 8, 1959], No. 26271/60. Heading F1S. [Also in Divisions F2, G3 and H5] A device for producing a large force on an operating member, e.g. diaphragm D, in response to a small electrical control signal comprises a boiler 10 in which liquid is vaporized by a heater H, and condenser F, the pressure in the boiler 10, and hence in the liquid in and surrounding the boiler and acting on the diaphragm D, being controlled by a valve R which controls the escape of vapour into the condenser F. The boiler 10, condenser F, and signal response device C are contained in a closed vessel V filled with the vaporizable liquid, e.g. "Freon" (Registered Trade Mark) or tetrachloro-ethylene, the bottom of the boiler 10 being open so that the liquid therein is in direct communication with the liquid in the remainder of the vessel. The condenser F is cooled by cooling vanes 12. The signal response device comprise a coil C in the field of a magnet M, the coil being connected to the valve R through a lever L pivoted at K which lever is connected to the operated member P, e.g. a valve, by a feedback link G. In equilibrium conditions the heater H produces vapour at a constant rate to set up a desired pressure in the boiler 10, which is communicated through the liquid to the diaphragm D, and the vapour is bled off through the valve R at a rate necessary to maintain the predetermined pressure. If it is desired to move stem P downwards to open the valve an appropriate signal operates coil C to close valve R, whereupon pressure builds up in the boiler 10 and the increasing liquid pressure forces diaphragm D downwards. The feed-back connection G ultimately reopens valve R slightly to re-establish equilibrium at the desired higher pressure. The heater H is carried by a floating device so that it only heats a small quantity of liquid near the surface. A capsule-operated pressure blow-off valve 8 and temperature responsive blow-off valve 7, operated by bimetallic strip 6, are provided in the boiler, the walls 16 of which are of low heat-conductivity material. In a modification the valve R is pressure balanced by a similar oppositely opening valve and in Fig. 4 the heater is situated in a stationary member 26 in which the liquid level is controlled by a float valve 30.

[Class 40 (v)] A constantly-rotated frame aerial 5, Fig. 2, generates one current from the received signal and another by cutting the earth's magnetic field, the two currents being compared with a third or " reference " current (supplied by a generator 15 rotating synchronously with the aerial) to give simultaneously an indication (a) of the angle 123, Fig. 1, between the axis 23 of the craft and the direction of the beacon-transmitter 1, and (b) of the angle 324 between the course of the craft and true North. As shown in Fig. 2, the H.F. signal pick-up passes through a filter 14 to an amplifier 12, whilst the L.P. current due to the earth's magnetic field passes through a filter 13 to an amplifier 11. Simultaneously the diphase generator 15 energizes a set of radiogoniometer coils 16 ... 19 to produce a rotating field to which the phases of the two currents are referred. The current from amplifier 12 will then indicate the bearing angle 123, whilst current from the amplifier 11 gives an indication of the " course " angle 324, the sum of the two giving the true compass bearing of the distant transmitter. The indications may be shown on compass cards 20, 22, Fig. 3, secured to two movable coils rotating in the field of the radiogoniometer 16. Alternatively the two angles may be shown as traces a, b, Fig. 7, with an axis of reference c, produced by applying short impulses from a commutator switch on the shaft of the rotating frame aerial ; the trace d shows the lubber-line of the moving craft.
