Abstract: 1389096 Colour television tubes HITACHI Ltd 28 Nov 1972 [29 Nov 1971 19 Jan 1972] 54876/72 Heading H1D A connecting lens for use in the lighthouse method of producing a shadow-mask colour television phosphor dot screen, which may be of block matrix type, has each surface divided into a plurality of areas of plane or curved surface by lines of surface gradient discontinuity, the superimposed lines on the two sides of the lens intersecting one another to define a plurality of lens regions designed to reduce misregister, while permitting easier manufacture of the lens than for the case in which all the gradient discontinuities occur on one surface of the lens. The lines of discontinuity may on each side of the lens be straight and parallel, but oriented in different directions on the two sides, e.g. perpendicularly in Fig. 5B, in which 903 represents a vertically oriented ridge, or the lines on one side may be concentric circles (Figs. 18 and 19, not shown). A variety of surface configura. tions is shown in the drawings; a central portion of one or both surfaces may be plane and perpendicular to the lens thickness (Fig. 23, not shown); and the area on one side of the lens may all exhibit on inclination in the same sense (Fig. 10, not shown), or may exhibit inclinations of opposite sense, as in Fig. 5B. The lens may be produced by applying an aluminium or silver film to a laquer mother mould; nickel plating on this film; and then casting thereon a substantial base layer of copper or nickel, whereafter the base and the metal layers are removed from the mother mould and constitute a final mould, between a pair of which a sheet of heated acrylic resin is pressed to form the lens. The lens may, alternatively, be formed by bonding together two resin sheets, each contained, by the above method, only on one surface.

Abstract: 1337683 Process and apparatus for continuously accumulating tubular net on tubular elements V CHERIO and G MIGNONE 25 Nov 1971 [21 Dec 1970] 54902/71 Heading B8C A machine for continuously accumulating tubular packaging netting 10 on tubular elements 1 comprises a saddle 22 which is movable horizontally on guide rails 23 on a frame 37, 38 and which carries, on a group of three radiallymovable pins 5, the flared end of a longitudinally aligned tube 1 adapted to receive a shirred length of netting, the saddle also carrying a seat with a retainer wall for receiving a roll of netting 10a with its axis vertical, and an adjustable brake 26 which provides a frictional force to oppose the movement of the saddle 22 along the guide rails 23. The machine also includes a pair of endless chains 13, 14 which are mounted for contra-rotation in a common horizontal plane on a table 4 supported by the frame 37, 38, and which carry groups of prongs 12, with end half-rings 12a which, when the chains 13, 14 rotate, move along opposite sides of the tube 1 to urge the netting rearwardly therealong and accumulate it in the vicinity of the fared end 1a of the tube 1. In use, the brake 26 is adjusted by a hand lever 28 according to the degree of netting compaction required, and the saddle 22, carrying a tube 1 securely located on the pins 5, is brought to its forward position adjacent the table 4, where the end of a roll 10 of tubular netting 10a is advanced through the interior of the tube 1, between a tensioning device 11, and through an axial hole 3a located in a removable blind end 2 of the tube 1. The tubular netting is then folded back over the exterior surface of the tube. The chains 12, 14, mounted respectively on sets of three pinions 15, 16, are then driven in unison by a motor 17 through belt and gearing mechanism 18, 19, so that the half-rings 12a on the prongs 12 urge the netting rearwardly to compact it against the flared tube end la. When the compacting force overcomes the friction of the brake 26, the saddle 22 moves rearwardly in the direction of the arrow F1, the compacting of the tubular netting proceeding until tubular netting has been shirred on to the full length of the tube 1, the saddle 22 has engaged stop members, not shown, and the tube 1 proper is out of the actionregion of the prongs 12. During the rearward movement of the saddle a cam wheel 31 on a pivoted lever 29 rides up a cam 32 on one of the guide rails 23 to pivot a lever end 33 toward a pair of pins 34 and provide a restriction on the feed of the tubular netting. The blind end 2 is then removed from the tube 1 by operating levers 35, 36 in proper sequence, the tubular netting then being cut and the tube 1, loaded with shirred tubular netting, being removed from the saddle 22 by operating a lever 6. The brake 26 is then released by operating a handle 28, the saddle 22 then being advanced to its forward position for a repeat operation.

Abstract: 1,215,020. Electron beam apparatus. VARIAN ASSOCIATES. 20 Dec., 1967 [22 Dec., 1966], No. 57829/67. Heading H1D. An electron beam tube includes a cathode 6, and accelerating electrode 4, wherein electrons emitted from the cathode and focused by electrode 8 to form a beam 3 are collected by collector structure 5 of the fly-trap type comprising a cavity 17 with an apertured wall 18 having a mouth forming a restricted beam entrance 19 which inhibits the escape of secondary electrons from the cavity, and an electric beamfocus structure 21 disposed at the mouth portion 19 of the collector which shapes the decelerating electric field in the presence of the beam to form equipotentials which are inwardly dished towards the collector, Fig. 2 (not shown), and include an equipotential 22 at collector potential extending across the mouth substantially normal to the electron trajectories. In the linear beam tube arrangement shown the spacing d 2  from a cathode 6 to the midplane of the accelerating electrode is preferably equal to the spacing d 1  from this midplane to the collector equipotential surface 22. A pair of shaped, aligned mesh grids 9, 11 may be arranged close to cathode emissive surface 7. The grids 9, 11 and the cathode may have central apertures 12 to permit the passage of positive ions which are collected by a target electrode 13, preferably made of getter material, e.g. titanium. Central beam passageway 14 in the accelerator 4 is of smaller diameter than the cathode emissive surface 7 and is longer than its diameter to prevent coupling between the input pulses applied to the grid 11 and the output from the collector 5. In a modification, Fig. 3 (not shown), the beam focus electrode comprises a number of separate, insulated apertured discs secured to cavity wall 18. In another embodiment, Fig. 5 (not shown), the tube is of the radial beam type with the beam directed radially outwardly from a central cathode emitter to a coaxial annular fly-trap type collector; this arrangement increases the power handling capacity of the tube. In any of the embodiments, a radio frequency resonant circuit 31 may be connected between the accelerating electrode and the collector, and a signal to be amplified may be applied to grid 11 to modulate the beam. Preferably, the pulsed potential of grid 11 is 1/30 or 1/50 of the potential of the accelerating electrode and the collector potential is depressed to nearly equal to the cathode potential, so that the forward conduction potential drop is 1-10% of the accelerating electrode potential. The input to grid 11 may be from a further resonant circuit. The collector 5 and accelerator electrode 4 may be water cooled. The tube may also be used as a switch tube.
