Title: Improvements in or relating to differential pumping-tubes for electrostatic particle accelerators
Inventor: HOWE FREDERICK ALBERT
IPC: H01J5/06
Filed: 1964-11-19
Abstract: 1,087,725. Particle accelerators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 11, 1965 [Nov. 19, 1964], No. 47158/64. Heading H1D. A differential pumping tube arranged in parallel with a D.C. particle accelerator tube and having potential distributing annular electrodes 1 along its length has each electrode comprising a diametral bar 4a, 4b bent out of the plane of the electrode, all the bars being bent towards one end of the tube. An electric field having a component towards the axis of the tube is thereby set up between pairs of adjacent electrodes in order to suppress electron loading. The bars may be bent to V- or arcuate shape and successive bars may be circumferentially displaced through a small angle. Also the inner periphery of each electrode may be bent from the plane of the electrode.

Abstract: 1395584 Measuring the mass rate of flow EI DU PONT DE NEMOURS & CO 13 Oct 1972 [15 Oct 1971] 47354/72 Heading G1A In a device for measuring the mass rate of flow of particulate solids 5 e.g. aggregates of pigmentary titanium dioxide which are arranged to fall under the action of gravity so that they form a "sheet" of moving material, a gamma ray source 6 (Americium 241) and a detector 9 are positioned on each side of the moving "sheet" so that the gamma rays pass horizontally through the sheet from one edge to the other (i.e. in an edgewise direction parallel to the face of the "sheet"). The output of the detector 9 may be used to control the rate of flow of the particulate material by controlling the speed of rotation of a set of helical screw feeders Figs. 2 and 3 (not shown) or a star valve Figs. 4 and 5 (not shown) which serve(s) to deliver the material to where it falls under gravity through a chute forming the "sheet". Several examples with measurements are disclosed.

Filed: 1972-10-20
Abstract: 1392863 Colour television FUJI PHOTO FILM CO Ltd 20 Oct 1972 [22 Oct 1971 (3)] 48519/72 Heading H4F A colour film 136 is scanned by a flying spot scanner 130 having a screen formed either of vertical (for horizontal scanning), differently coloured phosphor stripes, or a white phosphor layer covered with one or more striped colour filters, the transmitted signals being detected by a photo-detector 138 to generate a colour television signal. In one embodiment (Figs. 2, 3, not shown), two striped colour filters are used having alternate cyan/transparent and yellow/ transparent stripes respectively at different repitition frequencies, band-pass filters being used to produce respective red and blue signals which are matrixed with the output of a low pass filter to produce a green signal. In alternative embodiments (Figs. 4-7, not shown), repeating red, green and blue filter stripes or phosphor stripes at the same repetition frequency are used, and black or white index stripes may be included to produce an index signal to demodulate the resulting chrominance signals at the correct phases to produce red, green and blue signals. A filter or phosphor layer may be used having repeating red, green and blue stripes in the correct relative widths and transmissions or luminescences to produce an NTSC colour signal directly in the output of the photodetector. Repeating red, magenta, blue, cyan, green and yellow stripes of the correct properties may alternatively be used. When the phosphor layer or filter is such that an NTSC signal is directly produced in the photo-detector output, the flying spot scanner screen also includes a sequence of black and white stripes at one side, the light from which is fed via light guide 149 directly to the photo-detector 138 (or a separate detector), to produce a burst signal at the colour carrier frequency, which is compared in frequency at 152 with the output of an oscillator 151, any difference in frequency being used to control the width of the raster generated by flying spot scanner 130 to correct the colour carrier frequency. A rotating polygonal prism 165 is used to ensure correct scanning of the film frames by scanner 130.

Abstract: 1,101,719. Continuous casting. TUXON BRONZE Ltd. 6 Dec., 1965 [7 Dec., 1964], No. 49764/64. Heading B3F. To overcome adhesion to the mould, a continuously-cast solid or tubular bar is extracted by jaws 14 which intermittently grip and release the bar and rotate and advance the bar axially at each gripping stage. The mould may be static or reciprocated. The jaws 14 are mounted for radial movement in a cylinder which encircles the horizontal or inclined bar and are carried by a chain 20 secured at one end to the cylinder and at the other end at 40 to a handle 8. By pulling the handle, first the jaws are moved to grip the cast bar (or starter-bar) and then the cylinder and bar are rotated through a part-revolution. By virtue of the movement of a roller 15 in an adjustable cam member 62, the cylinder and bar are also moved axially slightly to extract the bar. The cylinder is held while the handle is returned to open the jaws 14 ready to repeat the movement. The operation may be automatic. The cylinder (3, 4), Fig. 1 (not shown), is mounted, for the limited rotation and reciprocation, in a housing (1, 2) having ball. ended screws (12) for supporting the bar.

Abstract: 1,144,924. Tape storage devices. PLESSEY CO. Ltd. 23 Nov., 1966 [24 Nov., 1965], No. 50005/65. Heading G5R. A cassette for holding a loop of information storage strip (preferably magnetic) comprises a chamber having substantially parallel sides between which a loop of the strip may be located in contiguous folds of predetermined size, the strip being movable into the cassette along an inner wall thereof, such inner wall including a point where there is a sharp change of direction in the line of the wall. As shown, an endless loop of tape 4 is withdrawn from the bottom of the tape chamber 2 of a cassette 1 by the drive of a tape transcription apparatus and is fed back into it at the top. At the inner end of upper wall 5 the tape strikes a re-entrant member 6 which causes the length of tape to be folded at predetermined intervals and the thus-formed folds fall into the curved portion of tape chamber 2. The lower folds are compressed by the folds above them in their passage through the chamber. The loops of tape are allowed to expand in an expansion chamber 7 from which the tape is withdrawn. The two branches of the chamber 2 are at different heights so that there is a tendency for the folded tape to flow (by gravity) from the upper to the lower. Instead of the G-form shown the chamber may be in the form of a U-tube. The inside of the chamber is preferably coated to give low friction and low static drag. The inertia, resisting changes of rate of movement of the tape, is kept to a low value by the absence of reels. A brake in the form of a perforated surface against which the tape is held by vacuum may be provided adjacent the exit from the chamber.
