Title: Improvements in or relating to Electron Image Storage and Display Devices
IPC: H01J29/10
Filed: 1967-11-28
Abstract: 1,173,989. Cathode-ray storage and display tubes. TEKTRONIX Inc. 28 Nov., 1967 [28 Nov., 1966], No. 54059/67. Heading H1D. In a direct-viewing bi-stable storage tube, the target structure comprises a "mesa'' arrangement of phosphor dots 24 capable of both bistable storage and display and an intervening phosphor matrix 20 capable of high brightness display, but with non-storage characteristics. The phosphor 20 is deposited in matrix cavities 18 from a suspension, the cavities having been etched in the glass faceplate 12 following a photographic resist pattern-forming process. A metal layer 22, e.g. of aluminium or gold, is deposited over the phosphor matrix 20 to act both as a light-reflector for the phosphor matrix 20 and as a collector electrode for secondary electrons emitted by the phosphor storage dots 24. The metal layer 22 may also serve as a signal electrode. Light from the phosphor storage dots 24 is transmitted through the glass mesa portions 26 of the faceplate 12. In manufacture of the target structure a lacquer layer is applied to the phosphor matrix 20 before deposition of the metal layer 22. A second lacquer layer is then provided over the metal layer 22 and the phosphor storage dots 24 formed in a photographic resist process in which the resist is exposed to light through the glass mesas 26. In this step the metal layer 22 isolates the phosphor matrix 20 from contaminating photosensitive material employed in the formation of the phosphor storage dots 24. Finally the structure is heated to remove the lacquer layers. The target structure is attached to a ceramic tube funnel 14 through a glass frit seal 16 and electrical connection is made between a conductive tin oxide film 28 beneath the glass frit seal and the metal layer 22 by an aluminium layer 30. In a modification of the target structure, Fig. 4 (not shown), a transparent conductive coating of tin oxide is provided on the etched surface of the glass faceplate 12 beneath the phosphor storage dots 24 and the phosphor matrix 20 and such coating may also extend through the glass frit seal 16.

Abstract: 1,160,537. Variable-ratio gears; valves. GENERAL TIME CORP. 13 Dec., 1966 [28 Dec., 1965], No. 55860/66. Headings F2D and F2V. [Also in Division F1] An adjustable-speed actuator for operating the discharge valve of an aerosol dispensing container at selected time intervals, comprises a synchronous electric motor 16 rotating a cam 82 anti-clockwise through a gear assembly which is adjustable by knob 106 to high speed, low speed and neutral settings. Cam 82 is slidable axially and is biased downwardly by a spring 78 so that, when the high point 83b of the cam drops off fixed stud 90, it engages portion 93 of a pivoted lever 92 to move the lever downwardly, by the action of spring 78, to depress the container valve actuating button 34, thus producing rapid opening of the valve for a short duration, depending on the speed setting. The discharge valve may be of the type giving a metered quantity at each actuation. Button 34 is released when lever 92 engages cam portion 83a. The actuator is mounted on container 26 by a ring of resilient fingers 44 engaging the container rim 40 and an apertured support member 30. The gear assembly comprises a motor output gear 50 driving a gear cluster 54, 56, 60 fixed to shaft 58, and a gear cluster 66, 68, 70 fixed to a bush 64 axially slidable on shaft 72, gear 70 continuously meshing with a gear 80 fixed to cam 82.

Abstract: 1184939 Cables COMPAGNIE GENERALE D'ELECTRICITE 8 Dec 1967 [8 Dec 1966] 55863/67 Headings H1A and A4D A polyphase cable for use at cryogenic temperatures comprises a central tubular metal portion conveying the cryogenic fluid and having metal fins radiating from it or arranged parallel to its axis, electric conductors appropriate to the number of phases arranged concentrically around or parallel to the axis of the central portion, the first conductor being so positioned and shaped that over that part of its surface adjacent the finned central portion, the distance between it and the surface formed by the outer surface of the tubular metal portion and the fins at any point is substantially constant, the other conductors being arranged with adjacent surfaces separated by the same constant distance, and thermal insulation surrounding and electrically insulated from the conductors. The finned central portion may act as one of the phase conductors. As shown in Fig. 1, the conductors 4, 5, 6 are shaped to conform with the fins 2 and are separated from the central tube and from each other by insulation 8, 9, 10. Non-continuous binding in the form of e.g. a screen or net, surrounds an outer insulating layer 11 so that the spaces 16 thus formed may be used to establish a vacuum and cryogenic conditions in thermal insulating layer 13 which in turn has a metal covering 14. For a hyper-conductive cable, i.e. one whose conductivity at 20 degrees of 50 degrees K is several hundred times that at normal temperatures, the conductors may be purified aluminium, beryllium or copper, the thickness of conductor 5 being preferably 1À1 times the thickness of the skin layer at the operating frequency. For super-conductive cables the conductors may be lead, niobium, niobium tin compound, niobium-zirconium or niobiumzirconium alloys. The conductors may further be lead or hyper-conductive metal coated with superconductive metal, the coating on conductors 4 and 6 being on the surface facing conductor 5 which is coated on both sides. The central portion may be of standard grade aluminium or copper if it is not functioning as one of the phase conductors, but should have a conductivity exceeding 3 x 10<SP>9</SP> mhos. per metre. In the embodiment illustrated in Fig. 2, four fins are at right angles to each other and roughly tangential to the central tube. Three conductors 4, 5, 6, i.e. one per phase, are situated in each quadrant so formed, the conductors corresponding to a particular phase being connected in parallel at the ends of the cable. In other embodiments Fig. 3, 4 (not shown), the conductors and fins are arranged in two symmetrical groups about a diametral plane.
