Title: Information storing display array
IPC: G09G3/22
Filed: 1972-09-20
Abstract: 1400814 Matrix displays ENERGY CONVERSION DEVICES Inc 20 Sept 1972 [1 Oct 1971] 43545/72 Heading G5C A display device comprises a plurality of row and column conductors with an isolating impedance, display producing means 14 and a bi-stable switch 13 connected between the conductors, at each intersection either condition of the switches persisting after all signal sources have been removed. The impedance and display producing means may be a single component, e.g. a L.E.D. or a neon tube. Other display producing means include incandescent lamps, electroluminescent devices, and liquid crystals. The element 14 and the switch 13 may be in series or parallel between the conductors. Semi-conductor switches are set to a low resistance state by a current exceeding a threshold value for a given time and reset to a high resistance state by a short high potential pulse. In one embodiment the switches are set by A.C. potentials 180 degrees out of phase applied to selected conductors and reset by short pulses of opposite polarity. Separate set and reset signal generators may be used. Sustaining potential may be D.C., sine or square wave A.C. To prevent cross-talk, a second switch (36), Figs. 3, 9 (not shown), may be added in series with each first switch. The second switch has the same resistance characteristics as the first but reverts to its high resistance state when the current falls below a minimum value. To improve reliability the resetting circuit may be made independent of the light emitting elements 14 by using a transformer 63 to apply sustaining potential to elements 14 whilst set and reset potentials are applied across elements 13, 36 in series. Two halves of the secondary winding 63a of the transformer form part of an A.C. bridge which is balanced by making a resistor 72 equal to the switch 13 in its high resistance state. When switch 13 is in its low resistance state the bridge is unbalanced and current passes through element 14. With this arrangement the array, Fig. 13, includes additional horizontal conductors 64...67. If D.C. sustaining potentials are used D.C. bridges are included. An electroluminescent panel comprises layers of e.l. material (92) Fig. 15 (not shown) and bi-stable s.c. material (94) between crossed conductor arrays (91), (95) with intermediate electrodes 93 between the layers at each intersection to improve contact between the layers at these locations.

Title: Apparatus for conversion of telephones connection in parallel to a common line to provide a private switching system
IPC: H04M1/70
Filed: 1972-03-01
Abstract: 1389017 Automatic exchange systems BAHBAM MECHANIC-ESFAHANI 1 March 1972 [2 March 1971] 44129/71 Heading H4K A circuit which enables a plurality of subsets to share a single exchange line, is adapted to receive dial signals over the exchange line and in response thereto to connect that exchange line exclusively to one subset and to supply locally generated ringing tone to that subset and is arranged also to return to conventional shared line working in response to failure of a local power supply. As described, the circuit is said to replace the party line circuit of a conventional party line arrangement. The circuit derives power from a local mains supply and if the supply fails a relay releases to connect the subsets in parallel and to the line to give continuity of service. A detector also monitors for exchange test potential on the party line and blocks a transistor supplying power to the relay causing the circuit to switch to the conventional mode for a short test period if the test potential is detected. When the circuit operates in the exclusive mode it functions like a concentrator concentrating calls to and from the subsets on to a single exchange line with the exception that the exchange is assumed to treat the party line as an ordinary subscriber line and that for incoming calls ringing on the party line is detected and the line looped through a resistor to provide an answer signal. The calling subscriber can then dial an extra digit 1, 2 or 3 transmitting 1, 2 or 3 pulses through the resistor. These are regenerated to enable one of three relays each of which is enabled in response to a pulse, disables any previously enabled relay, disconnects itself from the regenerator and connects an adjacent relay to the regenerator. A timer times out after a sufficient time for the dialling of the extra digit and the substation associated with the then enabled relay is selected. If no relay is selected the fourth or master substation is selected. Ringing tone is derived from the mains supply and its duration timed by a transistor timer. For an outgoing call the relays are enabled cyclically and when the relay associated with an originating subset is enabled a transistor detector responds cutting off the supply to the relays. If another subset goes off-hook while the line is engaged in an established call this cutting off arrangement prevents his relay responding and connects that subset to the tone supply.
