Title: Process of formation and acceleration of plasma and a gun for its application
IPC: H05H1/24
Filed: 1963-09-13
Abstract: 979, 090. Thermonuclear apparatus. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Sept. 13,1963 [Sept. 19,1962], No. 36221/63. Heading G6P. [Also in Division H1] A plasma gun comprises two coaxial and axially spaced ionizing electrodes between which a quantity of gas can be liberated; a battery of condensers connected between the electrodes through a spark gap, the discharge of the condensers being arranged to ionize the gas to form an expandable ring of plasma; and a third electrode external to and coaxial with the first two electrodes, of which one is arranged towards the front of the gun and is connected to the third electrode through a second battery of condensers. Referring to Fig. 4B gas can be admitted to the space between electrodes 2 and 3 via a tank 20 and a pneumatically operated valve 8 (the valve operating mechanism not being shown in the drawing). A condenser battery is then discharged, e.g. through a spark gap, across electrodes 2 and 3 to create a ring of plasma which expands. A second condenser battery is connected between electrode 2 and a surrounding electrode 6 and discharges through the ring of plasma, and the magnetic field produced by the current drives the plasma towards the open end of the gun. The gun may be used for producing thermonuclear reactions or for propulsion.

Title: Explosive-actuated fastener or stud driving tools
IPC: B25C1/18
Filed: 1958-11-11
Abstract: 900,951. Cartridge-operated fastener driving tools. OLIN MATHIESON CHEMICAL CORPORATION. Nov. 11, 1958 [Nov. 13, 1957], No. 36238/58. Class 119. Relates to a cartridge-actuated tool for driving fasteners into frangible material, e.g. concrete, which spalls readily. According to the invention, a heavy steel pressure applying pad 100 of 2-3¢ 1bs. weight, is carried by the shield plate 102 mounted by a sleeve 103 on the front end of the barrel 22, the assembly 100, 102, 103 being urged forwardly by a spring 111 and the pad 100 having a work surface contacting area extending outwardly from the axis of the barrel by a radial expanse of not less than 6 barrel bore diameters. This is regarded as the probable extreme limit of the surface outcroppings of the lines of fracture of the work surface occasioned by driving of the fastener and the pad is said to confine spalling to a small area immediately adjacent the driven fastener. The assembly 100, 102, 103 is urged forwardly against a muzzle nut 110 and the arrangement is such as to give angle fire control as described in Specification 788,055. A recess 120 in the muzzle nut 110 and an annular clearance 121 between the pad 100 and nut 110 concentrate and control the spalling to a small area adjacent the muzzle nut and decrease the spalling in the more remote areas. Pressure of the pad against the work surface is further increased by the explosion gases which are ejected into the sleeve 103 through barrel ports 22B.

Title: Improvements in or relating to files for the storage of microfilms
IPC: G03B21/64
Filed: 1957-11-21
Abstract: 861,478. Mounting film strips. CAMPBELL, J. J-L Feb. 20, 1959 [Nov. 21, 1957], No. 36312/57. Class 98(2) Microfilms 14, Fig. I. are filed for storage by being permanently enclosed between transparent front and back panels 10, 11 of which at least one is of adhesive material which bonds under pressure. The film can thus be projected without removing it from the file. The file can be made by the apparatus shown in Fig. 3. A strip 24 of transparent adhesive tape is unrolled from a drum 23, and a strip of developed microfilm 27 unrolled from a spool 26. They are passed together between rollers 31, 32, which press them into adhesive contact. A tensioning device is provided for adjusting the pressure between the rollers. The tape is slightly wider than the film, so that it projects along both edges. The double tape-film layer is fed into a shoot 67, a suitable length being cut off by a guillotine 47. From here it is led to a movable carriage 20 carrying the plastic strip 11, on which the tapefilm layer is deposited. The carriage is then caused to move to the left from the position shown in Fig. 3, the pressure of a spring-loaded roller 70 causing the overlapping tape edges to be bonded to the bottom strip 11, so that all three layers are now bonded into a unitary structure. According to the Provisional Specification, the transparent file may be made first and the film inserted therein afterwards.

Abstract: 905,911. Aircraft. HUREL, M. L., BERTIN, J. H., and LE NABOUR, M.P. Nov. 18, 1958 [Nov. 19, 1957], No. 37122/58. No. 37122/58. Class 4. An aircraft comprises a lift-producing rotor in a duct extending at right angles through a supporting surface of the aircraft, means for selectively supplying a flow of gas from a power plant to a jet propulsion duct or to a bladed wheel for driving the rotor, and lift increasing means disposed at the rear of the supporting surface. In Fig. 2, a turbo jet engine 3 may exhaust through a nozzle 3a located beneath the fuselage, or through ducts 7, depending on the positions of interconnected valves 8, 9, or other valve arrangements, see Figs. 2a and 2b (not shown). The rear end of the fuselage is curved upwardly, away from the exhaust gases from nozzle 3a. Alternatively, the nozzle may be above a downwardly curving fuselage. For direct lift, the ducts 7 direct the exhaust gases on to turbine blades 6 fixed to the periphery of rotors 4 (one shown) each situated in a vertical duct 5 in the wing. The wings should have an aspect ratio between two and five and an effective area about four times that of both rotors. Sweep back should be between thirty and forty-five degrees, and the centre of gravity of the aircraft should be between the 30 and 35 % wing chord stations. Each wing should be big enough to contain a circle coaxial with a rotor and one and a half times the rotor in diameter. Fig. 5 shows a section across one rotor and wing. Guide waves 10 are provided, of aerofoil section and 0À4 to 0À5 thickness/chord ratio. The inclinations of their successive chord lines to the rotor axis increases going forwards, and these inclinations may be adjustable by simultaneous pivoting about spanwise axes. To prevent separation of the flow about vanes 10, they may have leading edge slat members of variable incidence, and air may be blown from the trailing edges of the vanes or slat members, see Fig. 6 (not shown). The boundary layer may also be sucked into the vanes. The top of each duct 5 may be opened or faired off by spanwise extending flaps 16 each pivotable about a spanwise axis 17, by one or more worm and quadrant gears 19, 20, each worm 20 being actuated by a pinion 22 driven from a common chain drive 23 and a hydraulic or electric motor 25. When the flaps 16 are fully open, they diverge upwardly. The bottom of the ducts can be open or faired off by flaps 26 pivotable simultaneously about axes 27. High lift flaps 28, ailerons 29, and a rudder 30 are also provided. Reference has been directed by the Comptroller to Specifications 744,107 and 811,840.
