Title: Means for regulating the flow of liquid fuel to prime movers
Inventor: IFIELD RICHARD JOSEPH
IPC: F02C7/22
Filed: 1949-02-09
Abstract: 666,255. Gas turbine plant. LUCAS, Ltd., J. Jan. 20, 1950 [Feb. 9, 1949], No. 3523. Class 110(iii). [Also in Group XXIX] The flow of liquid fuel to a jet-propulsion engine or gas turbine is controlled by a liquid operated servo-mechanism under the control of means comprising a body part a containing a chamber and a pair of passages q, t, the passage t serving as an outlet from the chamber j and having a restricted orifice u, and the other passage q serving as a vent through which motive fluid from the servo-mechanism can pass into the chamber j under the control of a valve o located in the chamber and operated by a movable member such as the diaphragm k or an equivalent piston responsive to different liquid pressures. As shown the fuel supply is regulated by a swash-plate pump comprising a rotary part b containing one or more spring loaded plungers d. The part b has a radial passage w communicating with the pump inlet f whereby liquid fuel at a pressure proportional to the speed of pump is delivered to a chamber y above the diaphragm. The valve o is carried on a lever n actuated by the diaphragm k. The latter is loaded by a spring m. The obliquity of the swashplate is regulated by the servo-mechanism which comprises a spring loaded piston 2 in a cylinder r open at one end to the pump delivery passage g and at the other to a passage q. The two ends of the cylinder r are connected by a restricted orifice 6. The increased pressure in the chamber j due to the sudden opening of the valve o damps the control movement of the diaphragm. The servo-mechanism may control a fuel throttle or byepass valve instead of the pump swash-plate. The control mechanism may be separate from the pump and the servo-mechanism. Specification 577,016, [Group XXIX], is referred to.

In a radio frequency channel selector, for receiving apparatus such as television, a hollow rotary drum 12 supports a series of cards 19 and photo-sensitive elements 21 are mounted in a block of moulded material, such as plastics, which is fixed to a frame 5, 16 by a support-plate 22 disposed inside the drum, the arrangement is such that any one of the cards can be positioned so that the photo-sensitive elements located opposite perforations or transparent portions of the card are illuminated by one or more fixed electric lamps 24 located externally of the drum to provide a control voltage modifying the capacity of variable capacitance elements to tune the associated stages of the receiver. As shown, the photo-diodes are connected by a printed plate 22 to electronic circuits of the television receiver so as to effect selection of the channel corresponding to the punched card selected. The drum 12 is biased in a certain position by a spring 13. When the key TD (Fig. 4) is pressed, rod D moves the end g of a member 31 against a lever 6 which is driven anti-clockwise. A braid 9 attached to a shaft 10 on the lever 6 is pulled against the action of spring 13 and rotates the drum 90 degrees. Similarly by pressing the keys TE and TF, members 33 and 29 engage and move the lever 6 at h and j to move the drum to the 180 and 270 degree positions, respectively. When a key is pressed it releases any previously depressed key and its associated rod is locked by a device 4. Key TC merely acts to release any of the other keys and allows the spring 13 to return the drum 12 to the 0 degrees position, also key TC may operate the mains circuit-breaker A of the receiver. The lamps 24 and channel cards which are inserted in grooves 19 in the drum may be replaced through a removable part 35 of the casing of the receiver. The lamps have a reflector 18 which has a mirror (26, Fig. 3a, not shown), at the front so that the channel number (28, Fig. 3e, not shown), which is marked on each punched card, can be seen through a lens 27 in the casing of the receiver.
