Title: Apparatus for controlling the fuel supply to gas turbine engines
IPC: F02C9/16
Filed: 1955-04-29
Abstract: 799,934. Gas turbine plant. HOBSON, Ltd. H. M., and McCOURTY, W. D. April 30, 1956 [April 29, 1955], No. 12529/55. Class 110 (3). [Also in Group XXIX] Apparatus controlling fuel supply to a gas turbine engine during acceleration to a controlled speed comprises an engine driven fuel pump supplying the engine through two series orifices 2, 3, a valve 5 controlling orifice 2 to prevent excessive overfuelling during an initial critical engine speed range, a speed-governor controlled metering valve 8 controlling orifice 3 to regulate the fuel when the engine speed exceeds the critical range and to maintain the controlled speed, a splitter valve 15, 16 downstream of orifice 3 dividing the fuel between a line 19 leading to the engine and spill line 18, 13, and a device 28 subject to ram pressure for actuating valve 14 to increase engine fuel flow and decrease spill in response to increase in ram pressure. Valve 5 is actuated by piston 6 loaded on one side by spring 7 and spill pressure and exposed on the other side to centrifugal pump pressure. Valve 8 is actuated by fuel flowing through piston orifice 10 and controlled by a valve 12 actuated by a speed governor. Valve 14 is actuated by fuel flowing through piston orifice 24 and controlled by valve 26 actuated by a bellows 28 responsive to ram pressure. To ensure the percentage split of the flow is always a function of ram pressure irrespective of the controlled speed, the pressures downstream of the valves 15, 16 are made equal by a spill line valve 30 actuated by a diaphragm 31 responsive on either side to the respective pressures. In a modification valve 26 is hinged and actuated by a capsule, piston 23 is exposed to full pump pressure, valve 30 is a balanced double beat valve and its actuating diaphragm may have one side exposed to fuel pressure downstream of valve 15 or to combustion chamber pressure. Specification 712,646 is referred to.

Title: Improvements in or relating to fuel elements for nuclear reactors
Inventor: KENDALL JAMES WILLIAM
IPC: G21C3/06
Filed: 1955-04-30
Abstract: 778,881. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. April 27, 1956 [April 30, 1955], No. 12591/55. Class 39(4). A fuel element for a nuclear reactor comprises a fuel content of tubular form contained between inner and outer tubular sheaths, the inner sheath being formed of a different material from that of the outer sheath so as to collapse at a lower temperature than the outer sheath to discharge under gravity at least some of the fuel content along the inside of the outer sheath when predetermined temperature conditions are exceeded in the element. The outer sheath 12 may be of niobium and the inner sheath 11 of vanadium. Enriched uranium is contained between the sheaths and two molybdenum washers (not shown); above and below these washers are breeder tubes 14 of natural uranium. Fig. IC shows the lower end of a fuel element. The bottom of tube 14 rests on a natural uranium packing tube 16 supported on a niobium end plug 17 threaded into a stainless end steel fitting 18. An annulus 20, duct 21 and pluggable hole 22 are provided for filling the element with liquid sodium to improve heat transfer from the fuel to sheaths 11, 12. At the top end of the fuel element, Fig. 1A, there is a niobium end plug 27 screw fitted in a stainless steel end fitting 29 which is supported by a flanged end resting on a top plate 35. Liquid sodium enters through the mouth 40 and divides at channels 39, part flowing inside and part flowing outside the fuel element. At between 1000 and 1100‹C. there is a rapid breakdown of the vanadium inner sheath which forms an alloy with the uranium, and the fuel is then discharged by gravity so that there is no danger of a super-critical condition arising. Tungsten, zirconium, molybdenum, titanium or tantalum may be used for the outer sheath in placed of niobium, and chromium or nickel for the inner sheath. As an alternative the inner sheath may be of stainless steel, an 80-20 nickel chromium alloy, or a molybdenum /nickel twoply with the molybdenum next to the uranium. In an alternative method the inner sheath is of a material which melts at a suitable temperature or of a two-ply material which forms a binary entectic at a suitable temperature ; examples of this are a titanium /nickel or zirconium /nickel two ply material with the titanium or zirconium adjacent the uranium. In a further alternative the inner sheath is made of a material which alloys with the fuel content at one temperature but is prevented from so doing until a higher temperature is reached by a barrier layer which inhibits solid diffusion, for example a nickel tube coated with tantalum.

The casing 16 has a screw-threaded bore 15a to enable the easing to be threaded on to the screw-threaded end 6 of the steering shaft 1, the casing being received in the well in the steering wheel. The combination lock has a number of tumblers which in the locking position engage an annular groove 22 in the bolt 21, the position of the tumblers being controlled by finger-operated dials 23. To enable the bolt to be removed when it is released by the tumblers, a pin 24 is provided. A dummy bolt shorter than the bolt 21 can also be provided which is shorter than the bolt 21 so that it is long enough to pass into the bore 19 in the steering wheel but not long enough to enter the bore 20; the dummy bolt prevents the lock from being removed when the steering wheel is not locked to the tubular member 2. A flange 9a on the steering wheel prevents the bolt 21 from being cut.

Title: Improvements in and relating to gas meters
IPC: G01F3/22
Filed: 1932-05-04
Abstract: 394,794. Gas meters. DEUTRICH, J., 102A, Westendallee, Westend, Berlin. May 4, 1932, No. 12870. Convention date, May 4, 1931. [Class 54.] In order that a gas meter shall register correctly when overloaded the valves are operated to shut off the inflow of gas to the measuring chambers before the diaphragms reach the ends of their strokes. In the construction shown in Fig. 1 the plate 13 of the diaphragm 12 has still to travel a distance a to the end of its stroke when the inflow to the measuring chamber 11 is shut off bv the slide valve 5 which is operated by the plate 13 through a crank shaft 1 and connecting-rods 6, 16. Slots 17 may be provided in the parts b of the valve that overlap the inlet ports 7, 8 when the diaphragm is in its end positions. With increasing speed of the meter the gas inflow is increasingly throttled by the premature closing of the valve and the overlap may be so chosen as to correct or render constant the metering error. The amount of throttling and the period at which it occurs may be adjustable. Excessive stresses in the meter walls and diaphragm when the gas is throttled may be prevented by providing an auxiliary membrane 18 between the two measuring chambers. Fig. 3 shows a valveoperating mechanism in which a crank 2 operated by the diaphragm modifies the speed of a valve 5 having no overlap between its end positions I, III so that when the diaphragm is in its end position the valve has passed its mid-position at which the inlet port closes and has reached position 11 or IV. The valve is operated from a crank 2<1> on the shaft 1 of the crank 2 through links 19, 20, 21, the pivot pin between the links 19, 20 sliding in a guide 23 and the pivot pin between the links 20, 21 being carried by a link 25 connected to a crank arm 26 driven through gear wheels 28, 29, 30 by the crank shaft 1. In other constructions the premature closing of the valve 5 is attained by enlarging the angle between the two arms 2, 2<1> or by broadening the cross members of the valve box. When the measuring chambers consist of rigid bells a flexible membrane such as 18 may be provided or the measuring chambers may be connected to opposite sides of a floating bell. If lift valves are used instead of slide valves the valves are arranged to close initially only on one side and then to yield resiliently until complete closure is effected. Reference has been directed by the Comptroller to Specification 6463/12, [Class 54, Gas distribution].
