Title: A method of producing and hot working continuous hollow castings
IPC: B22D11/00
Filed: 1968-11-13
Abstract: 1,217,921. Continuous casting; rolling; forging; making billets. BOHLER & CO. A.G. GEB. 13 Nov., 1968 [13 Nov., 1967], No. 53842/68. Headings B3A, B3F, B3H and B3M. A hollow casting, e.g. of steel, is produced by the method described in Specification 1,088,909, i.e. a continuous casting is conveyed from a mould in a curved path, first downwardly, then upwardly to a level above that to which the molten core can rise, and then the hollow shell is compressed by at least one pair of rolls or at least one forging or pressing device (or more, in stages) so that the hollow space is eliminated and inner faces of the shell are welded together and subjected to hot working. For making billets of high-speed tool steel or ledeburitic Cr-steel for sheet or strip production, the shell thickness (controlled by adjustment of casting speed or direct water cooling) is not more than 50 mm. and there is a hydrogen atmosphere in the hollow space. The temperature of the casting is controlled by insulation or cooling to obtain the desirable hotworking temperature. Lengths may be cut from the strand, taking care to close the strand at the cutting point to exclude air, and reheated in a furnace to attain the hot-working temperature. Reference has been directed by the Comptroller to Specification 1,088,909.

Title: Continuous reheat magnetohydrodynamic generating duct arrangement
IPC: H02K44/12
Filed: 1964-11-06
Abstract: 1,032,317. Generators operating by electro-magnetic interaction with fluids. WESTING- HOUSE ELECTRIC CORPORATION. Nov. 6, 1964 [Nov. 27, 1963], No. 45339/64. Heading H2A. In an M.H.D. generator parallel combustion zones extending between the opposed electrodes are produced by non-homogeneously injecting additional fuel/oxidant as necessary to complete the combustion of the working gas into the generator duct. In the construction shown electrode segments 20, 22 confront each other across duct 16 through which working fluid flows in the presence of magnetic field 18. The ionized working fluid comprises combustion products including an excess of one of the combustion agents (fuel or air) into which the other agent (air or fuel) 36 is injected from struts 28, in a plane extending across the duct and spaced from the side walls, to produce burning 38 around the jet and thereby providing a high conductivity path extending between the electrodes; the quantity of material injected being sufficient to provide burning along the working length of the duct. In a modification the struts may be replaced by a series of jet nozzles spaced apart along the length of the duet where the downstream nozzles inject a lesser quantity of material to provide the required level of combustion along the duct.

The microporous film may be produced by cold drawing the elastic film until porous surface areas which are elongated perpendicular to the stretch direction are formed, hot drawing the film until fibrils and open cells which are elongated parallel to the stretch directions are formed and then heat setting the film under tension at substantially constant length to impart stability. The microporous film may be of an olefin polymer, a polyoxymethylene polymer, polyalkylene sulphide, polyarylene oxide, polyamide or polyester. The macroporous sheet may be a pin punched plastics film. In the examples microporous polypropylene film is bonded to pin punched polypropylene films using a heated embossing roll.

Abstract: 1,098,270. Automatic temperature reference control. DE LA RUE FRIGISTOR Ltd. Dec, 20, 1966 [Dec. 23, 1965], No. 54650/65. Heading G3R. The apparatus such as is disclosed in Specification 1, 014, 418 is provided with means to protect it from damage should the freezable fluid become completely frozen. The switch 19 controlling the thermo-electric cooling devices 11, 12 is mounted on a platform 17 loaded by a spring 18. A predetermined formation of ice in the chamber 5 causes the bellows 21 to expand thereby operating the switch 19, the bottom face 23 of the bellows coming into contact with the upper surface of the platform 17. Should further expansion of the bellows occur by continued freezing of the liquid in the chamber 5 downward movement of the platform 17 takes place against the spring 18. Thus the chamber, bellows and the switch are protected from damage by undesirable formation of ice in the chamber.

Abstract: 1,158,258. Rocket thrust deflection. BOLKOW G.m.b.H. 8 Dec., 1966 [10 Dec., 1965], No. 54941/66. Heading B7G. A guided missile has remotely controlled means for deflecting the jet efflux from a propulsion engine, e.g. a rocket motor, the angle of deflection being limited by the static pressure in the combustion chamber of the rocket motor. The jet may be deflected either by a spoiler 6 intercepting the jet downstream of the nozzle 5 or by a tiltable nozzle 5<SP>1</SP>. The deflection may be caused by an electromagnet 3, 3<SP>1</SP> attracting an armature in a lever arm 2, 23, causing this to turn about a pivot 18, whence the arm returns due to the pull either of another electromagnet 4 or a spring 25. In Fig. 1 the angle of jet deflection is limited by the insertion of a spacer 1 when the rocket combustion chamber pressure is high. In Fig. 6 the angle of jet deflection is limited by the electromagnet 3<SP>1</SP> being mounted on a plate 17 which can be turned about pivot 18 by a bellows 13, inflated with the combustion chamber internal pressure, compressing another spring 20<SP>1</SP>.

Abstract: 1457257 Photomultipliers EMI Ltd 6 Dec 1973 [13 Dec 1972] 57564/72 Heading H1D In a method of operating a photomultiplier tube, the tube having a photocathode 3, a dynode 4 and focusing electrodes 7, 10, there being periods in the operation when photoelectrons are diverted from impinging on dynode 4, the method includes the step of pulsing focusing electrode 10 to a potential negative relative to the photocathode potential during said periods, the first focusing electrode being conductively connected to said dynode electrode which is maintained at a positive potential relative to photocathode potential. The arrangement enables the tube sensitivity to be initially reduced when observing short duration, bright events such as in laser remote densitometers, and a rapid return to maximum sensitivity in view of the reduced likelihood of a build up of space charge at the photocathode. Focusing electrode 7 may be permanently connected to the first (or only) dynode 4, or may be connected externally. Switch means may enable electrode 7 to be connected to electrode 10, or to dynode 4 alone when the suppression feature is required.

Abstract: 1369798 Making wire harnesses HUGHES AIRCRAFT CO 14 Dec 1971 [31 Dec 1970] 58009/71 Heading B3A [Also in Divisions G3 and H2] Strand material is automatically dispensed along predetermined paths in accordance with a stored program; facilities being provided for retaining the strand along the paths and at a termination site on removal of a feeding means. As shown, Fig. 1, cable form boards 18 are mounted by clamps 19a on work-tables 19. Wire-dispensing heads 10 are mounted on opposite ends of a boom 14 of a positioning carriage 13 which is co-ordinately positioned by a numerical control system responsive to individually programmed blocks of a punched tape. The cable-form is made-up by dispensing wires 16 from heads 10 between wire termination sites 15 past retainers 17.  The wires are supplied from spools 11 over grooved guide rollers 26 to capstans 25, whereby wire tension is adjusted and the wire initially payed-out at a termination site. The wire emerges through a selected guide tube 22a. A termination site is perforated 40, Fig. 4, and incorporates a slit neoprene diaphragm 53. A selected guide tube 22a, in response to the programme, penetrates the diaphragm and is then retracted to a level at which the wire is to be formed, the wire end being retained by the diaphragm. The wire on the spools 11 is pre-coded by pinched sections which are sensed by a photoelectric device during a sensing period of the  programme, occurring when the selected guide tube is inserted in a diaphragm. The sensing of the section causes the wire to be payed-out for a distance which ensures that the wire extends from the feed-tube. It is stated that the two heads can be operated concurrently and in parallel to produce two cable-forms in a cycle or a tool substituted at one head for setting out terminate sites and retainer position. The heads can dispense material other than wire, such as fibres, fibreoptic material, or tubing.
