Title: Improvements in or relating to visual display systems
Inventor: REIFFEL LEONARD
IPC: G06K11/00
Filed: 1969-10-07
Abstract: 1293403 Television TELESTRATOR INDUSTRIES Inc 7 Oct 1969 49305/69 Heading H4F To enable an operator to add a line drawing to a television display, a transparent plate 20, Fig. 2, is provided for positioning over the display. The plate is coated with a resistive layer of tin oxide, a source 22 feeding a D.C. potential between the top and bottom of the plate and a source 27 feeding an A.C. potential between the two sides of the plate. The righthand side and bottom of the plate are earthed and chokes 25 and capacitors stop interaction between the sources 22 and 27. A conductive probe 34, held and used as a pencil by the operator, moves over the plate to produce the line drawing and picks up an A.C. signal and a D.C. signal respectively indicative of the probes X and Y co-ordinates. These signals are detected at 43 and separated out and fed to storage and/or display means 36. In one embodiment, Figs. 1, 6, 7, the storage and display means 36 produces a permanent line drawing which is viewed by a television camera 12 and the output of this camera is mixed with that from the standard television camera 11 viewing a live scene &c., to produce the combined display at 18. The display means 36 comprises, Fig. 7, a glass-fronted box 61, in which is a mixture of aluminium powder 64a and glass beads 76. Electromagnetically depressing piston 84 blows air through porous base 77 such that some of the aluminium powder 64 is blown on to and adheres to the glass front 62 by electro-static attraction. A grid 85 may be charged to increase the electrostatic attraction. The X and Y probe coordinate signals energize respective motors 68 and 69, Fig. 6, within the box 61, such that a carriage bar 71 is moved by a pulley 41 controlled by motor 68, to the X co-ordinate, and a platform carried by the bar 71 and moved by pulley 74 controlled by motor 69 is moved to the Y co-ordinate. A stylus 65 carried by the platform is thus moved in accordance with the movements of probe 34 and so removes the aluminium dust to reproduce the line drawing for viewing by television camera 12. The storage and display means 36 may comprise a storage tube scan converter 51, Fig. 4, the input beam being deflected by the X, Y signals. The storage means 36 may comprise a read-out/ erase digital storage disc, drum, core or delay line means, Fig. 8 (not shown), in conjunction with analogue/digital converter means, with the read-in terminal connectible to the read-out terminal for continuous storage and to the X, Y co-ordinate data input for a new line drawing.

Title: Improvements relating to electric signalling systems
Inventor: BIRD FRANK GEORGE
IPC: G08C15/12
Filed: 1963-12-18
Abstract: 1,022,305. Multiplex pulse signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 29, 1964 [Dec. 18, 1963; May 22, 1964], Nos. 49982/63 and 21237/64. Heading H4L. In a time division multiplex pulse codesignalling system, for synchronizing purposes the first time slot in each frame is occupied by an auxiliary pulse AP1, Fig. 2, and a predetermined number of time slots at the end of the frame (as shown five) are left unoccupied to provide a continuous SPACE signal, further auxiliary pulses AP2 to AP5 being allotted to certain other time slots to ensure that no other SPACE signal of the same duration can occur. At a reciver, Fig. 1, incoming pulses are supplied to a pulse shaper PS1 providing an output W/R. Immediately before the occurrence of the leading edge of pulse P1, i.e. the leading edge of pulse AP1, a pulse counter PC is in its count-of-four condition and accordingly applies an inhibiting condition to a pulse generator PG. Upon the start of pulse AP1 a reset circuit RC returns the counter to zero, thus allowing the pulse generator PG to start and supply pulses to a terminal T3 and to a pulse shaper PS2. The pulse generator operates at twice the recurrence frequency of the time slots of Fig. 2 and the shaper PS2 is of the divide-by-two trigger type and produces a brief pulse X in the centre of each time slot. For the duration of pulse P1 a gate G1 is inhibited and prevents pulses XP1 to XP6 from the shaper from stepping the counter PC. At the end of pulse P1 the gate G1 is opened and pulses XP7 and XP8 step the counter to a count of two but the leading edge of pulse P2 will reset the counter to zero and close the gate G1. The counter will only reach its count of four after the occurrence of pulse P4 and will then stop the generator PG and supply a pulse SP constituting a synchronizing signal at output terminal T2. In a modification, Fig. 3 (not shown), timing pulses are received on a separate channel from the transmitter via an INHIBIT gate which replaces the pulse generator PG and is similarly controlled by the counter PC. In this arrangement the clock pulse recurrence frequency may be variable. A system for multiplexing various telemetering, supervisory and control signals using the synchronizing arrangement of Fig. 1 is described. Means are included for transmitting a parity bit in the event that the number of pulses transmitted during a frame would otherwise be an even number. In this embodiment the frame are arranged in groups, each group consisting of a predetermined number of frames. The end of each group is indicated by the transmission of a continuous MARK signal for a longer period than would occur normally.
