Title: Improvements in or relating to electronic storage tubes
IPC: H01J31/64
Filed: 1955-04-15
Abstract: 792,103. Cathode ray storage tubes. COMPAGNIE GENERAL TELEGRAPHIE SANS FIL. April 15, 1955 [April 15, 1954], No. 10921/55. Class 39(1). In a cathode ray storage tube having separate writing and reading beams 5, 6, Fig. 1, on opposite sides of a charge storage target, the target is annular and comprises an annular conductive core 8, a plurality of thin U-shaped strips 9, partially overlapping one another in the radial direction, legs of the strips being on opposite sides of the target and the strips compressing an insulating layer and a conductive layer so as to form elementary storage condensers, the beam scans being in circular paths. The strips 9 may be aluminium anodized on one surface, or of mica metallized on one side with aluminium or gold, the conductive part being designated 10, and the core 8 is of aluminium. The metallic part of the strips 9 does not extend over the edges so that the elementary condensers are insulated from one another, Fig. 3 (not shown). The strips 9 can be on the inner (as shown) or outer periphery of ring 8. Secondary emission collectors 13, 14 ; 16, 17 are connected to wall coatings 15, 18 respectively ; collectors 13, 16 can be secured to an annular shield (not shown) secured to the target by insulating supports. In writing the operation is such that the secondary emission ratio of 10 is greater than unity so that a positive charge image is built up, the potential rise being limited by the potential of 13, 14 which are 100 volts positive to 8. In reading 16, 17 are at zero potential so that they repel the secondaries generated by the reading beam back to 10 so that the target is discharged. When the potential of the target elements becomes low enough, secondaries can be captured by 16, 17 and output taken off thereby.

Title: Improvements in book supports or reading desks
IPC: A47B23/00
Filed: 1927-04-23
Abstract: 290,804. Gauldie, K. April 23, 1927. Desks supported on the person.-A device for enabling a book to be comfortably supported in a reading-position on the body of the reader consists of a cross member, against which rests the back of the book, and guys or struts which may be connected to the body of the reader, or other means for laterally supporting the book. Fig. 1 shows a book supported on a ledge E on a lower crosspiece F, its top resting against an upper .crossbar A; a supporting-cord B, with a pad E, passes behind the reader's body, and the lower piece F rests against his body. The cord B may be passed through notches S to prevent shadows from falling on the paper. Spring tines C, preferably crossed, retain the pages open. One of thess has a hump which may be engaged with the other tine so as to hold both away from the pages. The other ends of the tines are fitted in spiral springs in the member A. The upper and lower members A, F are connected by lazy-tongs linkwork fitted with springs which tend to collapse it, and draw the members A, F together, thus securing the book between the ledges E, M. Short projections N engage the bookbinding. To prevent the ledges from crushing a soft-backed magazine, a strip of cardboard may be fitted between them, or a friction joint tightened by a thumbscrew or other means, may be fitted in one of the joints of the linkwork. A pivoted stabilizing-foot 0 may be fitted on the part F. In a modification, the bar A is omitted, and is released by corner pieces on extended arms of the lazy-tongs linkwork; these corner pieces engage the upper corners of the book. The tines C are mounted on the ledge E or part F, on the lower-edge of which may be fitted a flexible bowed strip for abutting on the body of the reader. In another modification, the ledge E is mounted on the linkwork so as to be vertically adjustable with respect to the part F, which further is fitted with two stabilizing-feet pivoted to the lowest edge of the part F. The rods G are slidingly mounted in holes in the part A, complete withdrawal being prevented by spring catches.

Title: Improvements relating to means for holding open windows and other hinged members
IPC: E05F1/00
Filed: 1956-04-10
Abstract: 838,094. Operating windows. THOMPSON, H. G. July 10, 1957 [April 10, 1956; April 20, 1956], Nos. 10933/56 and 12082/56. Class 20(3) [Also in Group XXV] A releasable device for holding open a window or other hinged closure member comprises a piston rod 14 which projects from a cylinder 10 and a pressure responsive non-return valve 25 which admits air to the interior of the cylinder behind the piston 16 and is provided with over-riding mechanical means for opening the valve to allow air to escape from the cylinder. The valve is opened by an actuating rod 27, projecting outwardly from the valve at 33, which displaces a ball 28 housed in a compartment 31 having a slightly larger diameter than the ball to allow the air to pass -at a slow rate. The device shown is particularly applicable for holding a roof window against gravity, the cylinder, which is mounted on the window frame, and the piston rod, which abuts the underside of the window, being of arcuate form and having their centre of curvature on the hinge axis of the window. When the window is opened manually the piston rod is driven outwardly by a return spring 21 and air is drawn into the cylinder. When the rod again takes the weight of the window the valve 25 closes and the air is compressed slightly to hold the window in the required position until the actuating rod 27 is operated to open the valve. The actuating rod may be operated automatically in response to temperature variations, or after a predetermined time. In a modification the valve 25 is remote from the cylinder 10 and is connected thereto by a flexible tube. A pump may be provided to deliver air to the cylinder to drive the piston rod outwardly to open the window, no return spring being necessary in this case. Several windows may be controlled simultaneously, their cylinders being connected to a common air valve and pump. The end of the piston rod 14 may have a resilient head 19, or may carry a rockably mounted ball thrust race which abuts a metal strip provided on the window.

Title: Printing mechanism
IPC: H04L13/06
Filed: 1960-04-21
Abstract: 945,604. Typewriters &c. SMITH-CORONA MARCHANT Inc. April 21, 1960 [July 24, 1959], No. 10992/62. Divided out of 945,603. Heading B6F. [Also in Division H4] In a printing apparatus employed in a type-wheel printer, comprising a rotatable type-wheel assembly and a print-hammer device having a hammer lever pivotally mounted adjacent one end for engaging and impacting a recording medium against a selected portion of the type-wheel, a portion intermediate the ends of the hammer lever is arranged to receive an operating impact for the printing operation, and the lever is provided with a bore into which is adjustably fitted the stem of a low-mass hammer head, the stem being longer than the bore and provided with retaining means to prevent axial movement of the hammer head out of the bore, and an abutment portion on the upper surface of the hammer lever engages a stop upon the impacted movement of the hammer lever so that the hammer head continues its movement relative to the hammer lever due to inertia to effect the printing operation. The axis of the bore is approximately radially aligned with the axis of the type-wheel upon engagement of the hammer lever with the stop. The printing mechanism is described in connection with the high-speed printer-reperforator described in Specification 945,603. The 5-unit code combinations are applied to selecting circuits which control the axial movement of an appropriate code character rod in two code wheels rotated synchronously with the type-wheel 286 carrying two rows of characters. Each code bar carries interference flanges arranged to effect tape-feed, tape-punching operation, printing action and retraction of the punch pins and of the actuator for the printing device. Any code bar, except those for " letters," " figures," word-space, line-feed, carriage-return and blank (all-spacing) has an interference flange engaging, when a bar has been selected and moved, a transfer lever 598 which engages a flange 662 on the actuator 660 for the lever 648, preferably made of nylon, carrying the printing hammer head 654. The member - 654, preferably of aluminium, is mounted on a spindle slidable in a bore at the end of the lever and having a flange to retain the printing head 654 in the bore. When the lever 648, impacted by the actuator 660, engages a stop member 626, which forms the stripper plate for the punch pins, the printing head 654 moves by inertia to press the message tape and inkribbon against the type-wheel 286. The axis of the bore on the lever 648 intersects the axis of the type-wheel 286 when the lever 648 strikes the stop member 626. The actuator 660, together with the punch pins is positively withdrawn, by a bail member 674 operated by a transfer lever controlled from an interference flange on the selected code bar. Case-shift is effected by moving the type wheel axially along its shaft to its " letters " or " figures " position in which it is held by a spring-biased detent until positively moved to the other shift position.
