Means for producing electrical energy from the fission of heavy nuclei comprises means for producing fission, means for collecting fission fragments, and field means for preventing electrons from reaching the collecting means. In one arrangement, Fig. 1 (not shown), a cathode coated with uranium, a grid, and an anode are arranged in an evacuated container which is subjected to neutron bombardment to cause fission of the uranium, the fission products being collected by the anode and electrons being repelled by the negatively charged grid. In a modification, Fig. 2 (not shown), the grid is omitted and a magnetic field is provided to deflect electrons away from the anode. In another arrangement, Fig. 5, uranium hexafluoride is circulated through a cylindrical chamber 42 provided with two electrodes 48, 50 and surrounded by a coil. A discharge is established between the electrodes to ionise the gas which is concentrated near the axis by the magnetic field produced by the coil. The chamber is irradiated with neutrons to cause fission in the uranium; a grid 60 prevents electrons reaching the wall of the chamber, and an electrical output is taken between the wall of the chamber and electrode 50. In Fig. 6, a plurality of plates 112 coated on each side with fissile material alternate with collector plates 110, grids being disposed between each pair of plates 110, 112. The assembly is sufficiently large to form a self-sustaining reactor, so that no external neutron source is necessary, and is surrounded by graphite reflectors 120, 124 and a moderator space 122 containing deuterium.

Patent GB-1350269-A (GB)
Title: Velocity-modulation tubes
IPC: H01J25/10
Filed: 1971-04-19
Abstract: 1350269 Velocity-modulated tubes VARIAN ASSOCIATES 19 April 1971 [15 April 1970] 27088/71 Heading H1D In a velocity-modulated tube-as described, a klystron or extended-interaction klystronthe beam of electrons projected from a gun to a collection passes in succession through a prebuncher resonant circuit, through a nextsucceeding floating buncher resonant circuit, and through output circuit means for excitation by the modulated beam, the drift tube interposed between the pre-buncher and floating buncher circuits providing a drift region corresponding to a reduced plasma angle # greater than 90 degrees, and preferably equal to 120 degrees, where wq is the reduced plasma frequency, Vo is the D.C. beam velocity, and I is the length of the drift space. It is shown that the space charge forces arising from the fundamental and second harmonic space charge waves reinforce one another in the vicinity of the centre of the electron bunches, but oppose one another in the inter-bunch regions, whereby the provision of an abnormally long drift space provides a period for continued drift of electrons towards the bunches before excessive degradation of the bunching within the bunches occurs. For the klystron shown, the pre-buncher cavity 5 is also the input cavity, and the reduced plasma angles corresponding to the drift lengths between the interaction gaps of cavities 5 and 11, 11 and 11<SP>1</SP>, and 11<SP>1</SP> and 13, are 120 degrees, 60 degrees, and 25 degrees, respectively. Alternatively, the prebuncher cavity 5 may be replaced by a plurality of cavities (e.g. 3, Fig. 7, not shown) to increase gain, the upstream one being the input cavity, the drift lengths between the cavities each corresponding to a reduced plasma angle of 60 degrees, and the different cavities being tuned to different fundamental frequencies in the vicinity of the pass-band of the tube, to broaden the latter. The velocity-modulated tube may alternatively be an extended-interaction klystron having single or cross-wound helix resonators.

Title: Composite spun yarn and process for producing the same
IPC: D02G3/38
Filed: 1975-06-27
Abstract: 1500769 Composite yarn TOYO BOSEKI KK 27 June 1975 [28 June 1974] 27209/75 Heading D1W Composite spun yarn (see Fig. 6) is formed alternately with one-directional spirals X and two-directional spirals Y, Fig. 4, wherein the length of X is greater than 80 mm and the average length of X minus the average length of Y is greater than zero. A bundle of short fibres 14 is led from a drafting apparatus 9 to a single gas false twist member 7 which false twists the fibres 14 to one direction, and a multifilament yarn of a courseness of less than 50 denier is fed by a roller 10 through preferably a tension controller 12 at a speed faster by 50% to 90% than the feed speed of the fibres 14 and at a tension. As a result the feed point of the yarn 4 reciprocates over a length of 50 mm. along the false-twisted bundle of fibres 14, which is untwisted after its passage through the member 7. As the bundle of fibres 14 is twisted to the direction of the arrow (see Fig. 2) it is given an S-twist rotation and the yarn 4 is wrapped around the periphery of the fibres 14 in the form of spirals as it covers the first part of the reciprocating motion whereby Z-direction torque develops in the yarn 4 which, when it reaches a maximum value, stops the traversing or reciprocating motion of the yarn and the yarn moves over the fibres 14 by the Z-direction torque producing reversed spirals over the already traced spirals until the Z-direction torque becomes zero and the yarn then obtains an S-direction torque. An anti-ballooning device 8 is provided. The false twist member 7 may be of the air vortex type. If the bundle of short fibres 14 is fed at high speed the tension controller 12 may be dispensed with in which case the action of the friction roller 10 produces sufficient tension on the yarn. The air feeder 11 may be positioned before or after the roller 10. The short fibres 14 may be composed of cotton fibres, wool fibres, acrylic fibres, or a blend of polyester fibres and cotton fibres. The multifilament yarn 4 may be composed of polyester filaments or polyamide filaments. Two multicolour-dyeable polyester filament yarns may represent the yarn 4 or two multifilament yarns, one polyamide yarn and the other a polyester yarn, are used as the multifilament yarn 4.
