Fluid-actuated valves.-A valve according to Specification 316,314 is further characterized in that the closure member is closed by inlet pressure admitted through an aperture to the back thereof, and opened by the suction action of cavitation produced in the outlet when an auxiliary valve is opened. A valve chamber b lying in the fluid stream is encased by a valve box d and carries a valve member a on its front end, its rear end being formed with a concavity e where cavitation takes place. The valve a has an aperture o in its front face, and a skirt a<1> which fits loosely in an aperture in the chamber b. An aperture g, larger than the aperture o, is provided in the base e and is controlled by a mechanically actuated auxiliary valve i. The valve a is held closed bv the inlet pressure admitted to the chamber b through the aperture o and is opened by the actuation of the valve i, first by reduction of pressure in the chamber b and then by the suction action of cavitation in the base e of the chamber b and the reduction of pressure at the surface p<1>, both tending to reduce the pressure in the chamber b. Gearing z allows of mechanical operation of the valve a or the operation of an indicator by the movement of the valve member.

Abstract: 907,272. Nuclear reactors; detecting neutrons. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 24, 1961 [Aug. 31, 1960], No. 30091/60. Class 39 (4). Apparatus for measuring integrated neutron flux comprises a sealed vessel having at least two compartments each containing an article sensitive to neutron flux over a range of neutron energies, the articles varying so as to be sensitive to different ranges. The cylindrical vessel 10, Fig. 1, has four compartments, a large one, 14, and three smaller ones like that shown at 12. These contain a cobalt wire in a magnesium alloy capsule, a nickel wire 17, a cobalt wire in a cadmium capsule, and a silica phial 20 filled with magnesium sulphate. One end of the vessel 10 is sealed by a plug 21 and the whole is housed in a container 25. The apparatus is placed in a desired position in a nuclear reactor for a period of time (e.g. nine months) and then removed. The container 25 and vessel 10 are then cut through at the point corresponding to the neck of plug 21 and the plug is also cut through to expose the compartments; the contents of the compartments are extracted and their activities measured. The cobalt wire in the magnesium capsule is sensitive to the whole range of neutrons, and the other materials to part neutrons only. The thermal flux can be deduced by subtracting the part flux from the total flux.

IPC: F23D11/24
Filed: 1952-11-27
Abstract: 752,334. Spray burners. SHELL REFINING & MARKETING CO., Ltd. Nov. 27, 1952, No. 30092/52. Addition to 699,162. Class 75(1). [Also in Group XXIX] In apparatus for mixing a liquid and a gas by spraying the liquid into a gas stream the liquid or the gas or both flow through control means comprising a hollow cylindrical valve 3, rotatably fitting in fluid tight manner within a cylinder 5 and having ports 4 registering with ports 7 in the cylinder, the ports 7 in the cylinder being tangential to the space within the valve and each port 4 in the valve having a maximum width measured in a circumferential direction greater than the wall thickness of the valve, the arrangement being such that as the flow of fluid into the valve increases it is directed tangentially to circles of successively increasing radii. Thus, in the position of minimum flow the fluid enters the valve 3 in the direction of the dotted lines 16, 17 and in the position of maximum flow it enters in the direction of the dotted lines 18, 19. The ports 4 in the valve may be directed radially or they may, as shown, be axial extensions of the ports 7. The apparatus shown in Figs. 1, 2 is a spray burner nozzle and liquid fuel is conveyed to the ports 7 by passages 8 formed between flats 9 on the cylinder 5 and an, outer casing 6. The fuel swirls in the interior of the valve 3 and in a frusto-conical chamber 2 in the cylinder 5 and discharges through a central orifice 1 in the cylinder. The valve 3 is rotated by a spindle 3a. The apparatus shown in Fig. 3 is a burner having an air register exemplifying the invention and comprising a cylindrical valve 14 rotatably mounted within a cylinder 11 secured to the front plate of a furnace, the valve having four rectangular apertures 17 and the cylinder having four tangential ports 13. A liquid fuel spray nozzle constructed as shown in Figs. 1, 2 is supported on the end wall of the valve 14 with the spindle 3a of its rotatable valve 3 rigidly secured by a bracket 23 to the cylinder 11. Consequently when the valve 14 is rotated by a handle 15 to regulate the air supply to the burner the cylinder 5 of the fuel spray nozzle rotates relatively to the valve 3 to regulate the fuel supply. The fuel spray nozzle may be replaced by that described in the parent Specification. Additional air may be supplied through oblique ports 38 in the end wall of the valve 14 and co-operating slots 39 in the cylinder 11, the ports and slots functioning as described in Specification 752,333. Further air may be supplied near the spray nozzle by ports 16 in the end wall of the valve 14 and these ports 16 may be oblique and co-operate with arcuate slots in the cylinder 11. The ports 38 and 16 may be arranged to open before the ports 13.

Title: Means for controlling the speed of ram jet-propelled air craft, missiles or other aerial bodies
Inventor: LAWRENCE OWEN NAPIER
IPC: F41G7/30
Filed: 1950-12-13
Abstract: 710,412. Jet propulsion plant. LUCAS, Ltd., J. Dec. 4,1951 [Dec. 13, 1950], No. 30418/50. Class 110(3) [Also in Group XXIX] The speed of a jet-propelled aerial body at above the speed of sound is controlled by regulating the fuel supply thereto in dependence on the position of the shock wave associated with body. In Fig. 1, the supply of liquid fuel to a burner c in a hollow aerial body e is controlled by a throttle a supplied by a pump b. The throttle a is actuated by a spring- loaded servopiston g controlled by a vent valve i operated by a spring-loaded lever m connected to a diaphragm (or piston) p. The diaphragm p divides a chamber q into two compartments connected by passages r, s to two axially-spaced ports in the air intake of the body e. Normally the pressures acting on the diaphragm are substantially equal so that the vent valve i, is closed and the throttle a is open. When the shock wave is located between the passages r, s. the pressure rises in the passage s so that the vent valve i opens and the throttle a moves to shut-off or restrict the fuel supply and so limit the forward speed of the body. In a modification, the side of the diaphragm p open to the passage s is conected to an evacuated capsule so that the diaphragm now responds to the ratio of the pressures in the passages r, s which may therefore be located further apart than before. In a further modification, Fig. 3, the passage s is dispensed with and the vent valve i is operated by an elastic evacuated capsule n open to the passage r. The throttle a is actuated by a servo-piston g similar to that in Fig. 1 and the pressure drop across the throttle a operates through a diaphragm (or piston) 12 a further vent valve 8 controlling a servo-operated throttle 2 downstream of the throttle a. The fuel supply may alternatively be controlled by a spill valve or by otherwise regulating the output of the fuel pump b. Specification 603,155. [Group XXXIII]; is referred to. According to the Provisional Specification, auxiliary means may be provided to prevent the speed of the body increasing to such an extent that the shock wave lies ahead of the body. Such means comprise a further servo-vent . valve operated by a diaphragm (or piston) open to the atmosphere on its forward side and to the forward compartment of the first diaphragm on its rear side.

Title: Apparatus for conducting a sale by progressive bidding
IPC: H04L12/18
Filed: 1972-06-29
Abstract: 1370500 Progressive bidding apparatus D LE BRIS 29 June 1972 [30 June 1971] 30469/72 Heading G4H Apparatus for conducting a sale by progressive bidding comprises a display panel 1, buyers' desks, 2 1 ,... 2n, an auctioneer's desk 3 and a control circuit 4 comprising a totalizer 51 and a relay 59 corresponding to each buyer's desk. At the start of an auction, the auctioneer sets, by means of a keyboard 41, a reserve price on a display 21 on panel 1; if the bidding is to proceed by uniform increments, he feeds the value of the increment into the totalizer 51. To start the bidding, a switch 43 is closed to actuate a start/continue bidding display 23 on panel 1 (the connection being via closed contacts 61 of push buttons 50 in the buyer's desks); switch 43 also allows power to be fed to relays 59. When a buyer wishes to bid he pushes his button 50, thereby opening contacts 61 (whereby 23 is extinguished) and closing contacts 60: the respective relay 59 is thereby energized so that contacts 62 open and contacts 63 close. Closure of contacts 63 causes power to be supplied to an indicator 49 on desk 3 so as to indicate the buyer's number to the auctioneer; the closure also energizes an indicator 37 which tells the buyer that his bid has been accepted; finally, the closure feeds a pulse to the totalizer which causes the bidding increment to be added to the bidding total displayed on 21. Opening of contacts 62 isolates the relays 59 corresponding to the other buyers so that only the first bid is registered; it also ensures that all the remaining indicators 37 are not energized. Finally, the auctioneer opens switch 43 to deenergize the relay 59, and then closes it again in readiness for the next bid. In a modified embodiment (Fig. 2, not shown), desk 3 may include indications of whether each buyer is solvent and of how many buyers have made a particular bid. It may also include means which isolate a bidder from the auction, means which control final acceptance of a bid and means which control refusal of sale (the last two being linked to displays on panel 1). The display panel may also indicate the bidding increment (if fixed) and the number of the highest bidder. The buyers' desks may have keyboards or telephone dials for making bids of any desired amount, and each relay 59 may be electronic and/or self-setting (instead of being controlled by switch 43).

Title: Treatment of textile materials and films
Inventor: BURKITT FRANK HARRY
IPC: D06M13/278
Filed: 1963-08-01
Abstract: Films and textile materials comprising a major proportion of hydrophobic polymeric material, e.g. polyethylene, polypropylene, nylon, polyethylene terephthalate, polymers and copolymers of acrylonitrile and cellulose triacetate, are rendered antistatic by treating them with a polymeric substance containing at least one reactive -OH, >NH or -SH group and a substance capable of giving rise to divinyl sulphoxide or a substituted divinyl sulphoxide, and generating the divinyl sulphoxide or substituted divinyl sulphoxide and reacting it with the polymeric substance.  The term "a substituted divinyl sulphoxide" refers to compounds having the formula SO(CR3=CHR4)2 in which R3 and R4 are lower alkyl groups containing 1-3 carbon atoms and may be the same or different or one of R3 and R4 is a lower alkyl group and the other is hydrogen.  The substances giving rise to divinyl sulphoxide or a substituted divinyl sulphoxide may have the formula SO(CHR1CHR2 OY)2 in which R1 and R2 are hydrogen or lower alkyl groups and Y is hydrogen or the residue of an acid, e.g. bis-b -hydroxyethyl sulphoxide and its esters with sulphuric acid or phospheric acid and the sodium, barium and potassium salts thereof.  The polymeric substance may be starch, a starch ether, carboxymethyl cellulose, a hydroxyalkyl cellulose, glue, gelatin, a condensate of a polyol or polyamine with an alkylene oxide or a polyalkyleneoxy derivative of an amide or amine.  The conversion into divinyl sulphoxide or a substituted divinyl sulphoxide or substances which give rise to these compounds and the reaction thereof with the polymeric substances may be effected by the catalytic action of a alkali, e.g. an alkali metal hydroxide, bicarbonate, or carbonate, ammonium carbonate, trisodium phosphate, sodium sesquicarbonate, borax, an amine or a quaternary ammonium hydroxide.  The textile material or film may be treated with the polymeric substance, the substance giving rise to divinyl sulphoxide or a substituted divinyl sulphoxide and the alkali as an aqueous solution, emulsion or dispersion either simultaneously or consecutively in any order, dried at 50 DEG -220 DEG C for from 20 seconds to 1 hour, rinsed, neutralised and dried.  The treatment may be carried out in conjunction with or after other chemical or mechanical finishing treatments to confer resistance to shrinkage or creasing, modification of handle or surface lustre or optical brightness.  Polyethylene terephthalate film treated with hydroxyethylated cellulose, bis-b -hydroxyethyl sulphoxide and soda ash may be given an affinity for direct cotton dyestuffs and rendred antistatic.

Title: Improvements in mechanical stokers
IPC: F23K3/00
Filed: 1950-12-15
Abstract: 692,645. Mechanical stokers. BABCOCK & WILCOX, Ltd. Dec. 15, 1950 [Dec. 15, 1949], No. 30644/50. Addition to 692,629. Class 51(i) [Also in Group XXX] In combustion apparatus as claimed and described in the parent Specification regulating means are provided for varying the track lengths on the feed plate over which the fuel particles move. As shown coal from a hopper 1 is fed over a shoot 2 to reciprocating feeding rams 3 which move over an adjustable slide plate 8 below which is a compressed air chamber 9 provided with nozzles 10 for the discharge of air over an upwardly inclined feed plate 11. Extending below the hopper is the front portion of a travelling grate 12 and fuel is pushed by the rams to fall over the inner edge of the plate 8 on to the plate 11 which provides a track along which the fuel particles are carried by the air blast into the furnace chamber 13. The amplitude of the rams 3 is adjustable and the plate 8 may be given an oscillatory motion whilst a drop door 7 may be used to vary the gap through which the rams project the fuel. The travel of plate 8 may be such that when it is fully extended fuel is not intercepted by the plate 11 but passes directly to the grate. A number of feed units each comprising ram, plate 8, plate 11 with associated nozzle may be arranged side-by-side across the furnace. Further, a plurality of slide plates 8 may be arranged across the width of a feed plate 11 each being independently controlled so that the track lengths at different locations across the plate 11 may vary. Automatic means may be provided for separately oscillating the plates. Again the plate 8 may comprise a number of side-by-side strip-like plates arranged in two sets alternating with one another each set being simultaneously movable in opposite directions. The edge of the plate 8 may be of wavy, ziz-zag or castellated form and the plate may comprise two relatively movable laminae-one having an edge of said wavy &c. form and the other a straight edge, movement between the two varying the effective length of the projections of the wavy &c. edged laminae. The laminae may be arranged to move together under the action of automatic oscillating means or they may be separately oscillated with different amplitudes of movement.
