IPC: B42F13/12
Filed: 1957-06-11
Abstract: 879,113. Filing papers. CAKEBREAD Ltd., C. June 11, 1958 [June 11, 1957], No. 18429/57. :Class 146(1). , In a loose-leaf binder comprising a pair of ;cover members connected by a spine member and at least one binding post which is engageable with holes formed in the leaves to be bound and which consists of two co-operating parts, one part extending from each cover member, the two parts are slidable relatively to one another to allow the overall length of 'the binding post to be varied and one of the parts is connected to one of the cover members by releasable locking means carried by the said cover member. As shown a plurality of tubular sleeves 13 is mounted on a bar 4 secured to one leaf of an elongated hinge 5 of which the other leaf is attached to a cover member 1. A casing 6 containing the locking means is mounted on one leaf of a second hinge 8 of which the other leaf is secured to the cover-member 2. A plurality of rods 12 in telescoping relation with the sleeves 13 is mounted on a bar 11 which carries two spigots 15 on its rear face, which spigots pass through holes in the casing 6 and engage the locking means therein. The cover-members are connected by a flexible spine 3 which is of such width that the rods 12 and sleeves 13 can only be moved out of telescoping engagement after disengaging the spigots 15 from the casing 6 by actuation of a trigger 7. Thus the rods and sleeves can be telescoped when the binder is closed until the length of each composite binding post constituted thereby is equal to the thickness of the bundle B of leaves to be filed, and can be moved in the opposite direction when the binder is opened to .facilitate reference to the individual leaves. In modifications the rods 12 may be fastened to the bar 4 and the sleeves 13 to the bar 11 or each bar may be provided with both rods and sleeves. According to . the Provisional Specification a lifter bar may be provided having holes through which the sleeves 13 may be passed before the leaves are threaded thereon and additional posts which pass through further holes in the leaves. The leaves are removed from the binder by lifting the lifter bar, and thereby the bundle of leaves, off the sleeves 13.

Title: Television image display device
IPC: H04N9/12
Filed: 1961-05-23
Abstract: A television display device consists of crossed conductors 25 . . . 610, 11 . . . 7811, Fig. 1, exciting (with video impulses from B) electroluminescent material at their junctions, the conductors being switched at frame and line frequency respectively by photo-conductors F25e . . . F610e, F11 . . . F1781 which are excited by separate switching circuits composed of combinations of mutually interacting electroluminescent (e.l.) and photo-conductive (p.c.) elements.  The frame-scanning circuit, with which the invention is concerned, consists of a number of series-connected circuits each comprising a basic unit of an e.l. element, L25, Fig. 2 (which excites the p.c. element, F25e) which is switched on by a series combination of a " preparatory " p.c. element F25b (which is excited by the preceding e.l. element L23) and a " switching " p.c. element F25d excited by the line-impulse e.l. element LZ.  After switching on, the element L25 excites F25b and F25d for self-maintenance.  At the next line-impulse L27 is similarly excited and this illuminates p.c. element F27c which short-circuits L25 and extinguishes it.  Thus the illuminated condition is propagated successively along all the odd line elements in bank I, and then along the even line elements in bank II, for interlace; multiple (e.g. fourfold) interlacing may be used for colour systems.  The first 24 switching units are unconnected to lines.  The line, picture and interlace switching are performed by line and picture e.l. elements, LZLB which in turn control e.l. elements LA, LC, LD and p.c. elements Fa, Fb, F1d, F2d, to give correct synchronization and interlace.  The line-scanning circuit consists of a number of e.l. elements L11 &c., Fig. 3, each connected across a p.c. element F11 and exciting the next element F12; these elements L11 are of the type which only lights under a changing voltage, <PICT:1009046/C4-C5/1> <PICT:1009046/C4-C5/2> <PICT:1009046/C4-C5/3> <PICT:1009046/C4-C5/4> <PICT:1009046/C4-C5/5> so that they are self-extinguishing.  The circuit elements above described are integrated with the display device into a single plate. A cross-section through the edge forming the equivalent of Fig. 2 is shown in Fig. 5 and shows the picture e.l. layer 1001, line and frame conductors 7811, 610 &c., p.c. layer 1010 equivalent to F610e &c., oxide layer 1011 for video, insulating glass plate 1012, oxide layer 1013 for supply voltage, e.l. layer 1014 equivalent to L610 &c., and LZ, LA &c., and oxide electrodes 1015, 1016, 1017, 1018 co-operating respectively with LZ and with p.c. elements grouped in the layers 1019 . . . 1023. A cross-section through the other edge corresponding to Fig. 3 is shown in Fig. 6 and comprises the e.l. elements L1 forming the edge of layer 1001 and the associated p.c. elements F1 with staggered connectors 10231.

Abstract: 611,513. Viewing objects by use of heat-responsive devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 25, 1945, No. 19113. Convention date, Dec. 28, 1943. [Class 40 (iii)] In a system for producing on a cathode-ray tube a visible image of an object radiating or reflecting heat, an image of the heat radiation of the object is reflected by a concave mirror 1 on to an oscillating mirror 3 which traverses successive strips of the image over a row of heat-sensitive elements 19 which are made operative sequentially by a spiral slot 5 in a disc 7. The elements are individually connected through isolating resistors 23 and condensers 25 to valves 27 and a single amplifier 31 whose output is fed to the control grid of the cathode-ray tube 33. Scanning potentials for the horizontal and vertical deflecting plates 35, 37 respectively of the tube 33 are derived from circuits 39, 53 energized by pulses produced from a fixed plate 45 associated with teeth in a wheel 43 on the shaft 13 of the disc 7 and from a fixed plate 61 in conjunction with a plate carried by the oscillating mirror 3. In a modification, Fig. 2, the heat-sensitive elements 79 are individually connected to diode rectifiers 85 to charge condensers 87 connected to contacts 89 engaged by a rotary arm 93, driven by a motor 111, to apply the charges to the control grid 99 of the cathode-ray tube 101. The control potentials for the horizontal and vertical deflecting plates 103, 107 respectively are derived from a potentiometer 105 driven directly from the motor 111 and from a second potentiometer 109 driven through a gearing arrangement 113 which oscillates the mirror 75 to traverse the strips over the elements 79. The heat-sensitive cells may be as described in Specification 601,070. U.S.A. Specifications 2,175,692 and 2,288,766 also are referred to.
