Title: Improvements relating to data display arrangements
Inventor: FROGGATT ROBERT JUSTIN
IPC: H04N3/02
Filed: 1960-11-15
Abstract: 1,002,124. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 15, 1961 [Nov. 15, 1960], No. 39129/60. Heading H4F. In an arrangement for displaying data (e.g. stock exchange prices or airline flight information) of a number of remote positions the data is supported by a curved surface 1 and scanned by a rotating double-sided mirror 2 (frame scan) and a flying-spot tube 7 (line scan) to derive, via a photo-sensitive device 10, corresponding electrical signals which are supplied to a plurality of display units 12 each including a display tube 19 the line scanning generator 13 of which is controlled by synchronizing signals from a photo-electric generator 5 driven by motor 3 (which also drives the mirror 2 via a step-down gear-box 4) such synchronizing signals also controlling the scanning of tube 7 and the frame scanning generator 15 of tube 19 via a divider 14. In the described embodiment ten groups of data are mounted on surface 1 and to enable any one of such groups to be viewed to the exclusion of the others the video signals are supplied to tube 19 via a gate 18 which is " opened " by signals from a selected one of ten output contacts of a ring counter 16 to which frame frequency pulses from divider 14 are supplied the tube 19 having a long persistence phosphor so that intelligible reproduction is achieved despite the comparatively low repetition rate at which data is supplied thereto. The practical details of the operation are: Motor 3 operates continuously at 3,000 r.p.m., generator 5 produces pulses at a repetition frequency of 5 kc/s., gear-box 4 has a 100: 1 reduction ratio and divider 14 has a ratio 500: 1 so that during one half revolution of mirror 2 the surface 1 is completely scanned in 5,000 (vertical) lines and 10 frame synchronizing pulses are produced. Each group of data is therefore scanned by 500 lines with a repetition frequency of one-tenth second for any given group. The surface 1 may have permanent information painted on it (both inside and outside) and may be provided with holes and slots to enable tablets bearing variable data to be inserted from outside. The rotating mirror 2 may be dispensed with and the frame scan produced by rotation of the surface 1 and to avoid damage to the screen of tube 7 the beam of the latter may be given some deflection transverse to the (line) scan the effect of such deflection being removed by a cylindrical lens. The scanning by tube 7 may be arranged to produce signals suitable for reproduction by interlaced scanning and in large arrangements fifty groups of data each scanned by 405 lines may be used so that existing television monitors may be employed for display with a minimum of modification. In the described embodiment the tube 19 may be replaced by a storage tube and means provided for reading its contents.

Title: Nacreous material
IPC: C08K3/00
Filed: 1964-09-29
Abstract: Nacreous material comprises suspended in a solid transparent resinous material, irridescent lamellae each of surface area at least 0.2 sq. mm. and carrying a metal oxide glaze.  The lamellae are preferably made of glass, mica or ceramic material and are preferably 0.01 to 1 mm. thick and preferably have a surface area of 1 to 25 sq. mm.  The lamellae may be used in conjunction with a nacreous pigment.  The irridescent lamellae can be prepared by applying a liquid metal oxide glaze to a thin sheet of mica or glass, then heating the coated sheet followed by limited cutting up or grinding of the sheet.  The resinous material may be thermoplastic, e.g. polystyrene, acrylic resins or cellulose esters, or thermosetting, e.g. polyesters or aminoplasts. The irridescent effect can be modified by adding a soluble dyestuff to the resinous material.  In the Examples: (1) a polyester/styrene resin mixed with catalyst has added thereto glass lamellae with a TiO2 glaze and mother of pearl pigment, and the mixture then cured; (2) a sheet of glass is coated with a blue-coloured cellulose acetate solution containing glass lamellae having a titanium dioxide glaze.  After evaporation of the solvent the resulting sheet is bonded between a sheet of cellulose acetate containing a mother-of-pearl pigment and a colourless sheet of cellulose acetate, and (3) a sheet of polystyrene is coated with a layer of a suspension in styrene of mica lamellae having an iron oxide glaze.  The layer is then covered with a sheet of polystyrene and polymerized.

Abstract: 829,385. Burglar alarms. HARRY, F' Dec. 30, 1957 [May 17, 1957], No. 40322/57. Class 118 (1). [Also in Group XXV] In a lock 10, a single-pole, single-throw type switch 70 is mounted beneath a sliding bolt 23 and the contacts of the switch are spring- biased to the closed-position, but may be held open by means of a lever having a roller 72 which normally bears against the underside 76 of the bolt 28. The latter is normally aligned in the direction of its sliding motion by means of springs 66 and 68, but if an attempt is made to force the bolt the springs yield to permit limited transverse pivotal movement of the bolt to either of the positions shown dotted in Fig. 4, which releases the roller 72 and allows the lever to move upward, thereby closing an alarm circuit, Fig. 7 (not shown). The bolt 28 is formed with a heavy end section for engaging a strike (not shown) and a thinner body 30 upon which is pivotally mounted a pawl 46, the latter being spring-biased in the upward direction and provided with a ratchet 54 which engages a boss 42 projecting from the lock cover 24, to retain the bolt in the locked position. The bolt 28 is operated by a cam 16 which is moved by the tang 26 of a barrel lock, the cam 16 engaging a lug 52 on the pawl 46 to disengage the ratchet 54 and allow retraction of the bolt. Preferably, two barrel locks are provided, one on either side of the door to which the lock is attached by means of screws passing through the lock cover 24. A depression 78 in the underside 76 of the bolt 28 permits the roller 72 to move during operation of the bolt 28 momentarily to actuate and thereby test the alarm. The lock may be of the mortise type.
