Filed: 1972-09-29
Abstract: 1366569 Gas discharge display panels OKI ELECTRIC INDUSTRY CO Ltd and OKAYA ELECTRIC INDUSTRY CO Ltd 29 Sept 1972 [30 Sept 1971 (3)] 45031/72 Heading H1D A cold cathode discharge display apparatus includes, within a gas-filled envelope, a layer of first electrodes separated from an opposed layer of second electrodes by an insulating spacer formed with a plurality of discrete discharge cells; a layer of discrete starting electrodes for the cells; and a plurality of resistors respectively connected in circuit with the second electrodes. As shown in Fig. 1, groups of aligned perforations form a succession of similar display units. A cold cathode common to all the units is formed by metal 12, Fig. 4, deposited on the walls of the perforations of, and on the upper surface of, the layer 4; separate starting electrodes for each cell are formed by conductive coatings on the walls of the perforations in the layer 6, corresponding starting electrodes of different units being connected together; and separate anodes for each unit are formed by conductive layers 16, Fig. 4, deposited on the upper surfaces of series resistors formed by glass or ceramic powder fillings of the perforations of the layer 8, the lower faces of the resistors connecting with the conductive areas 17a to 17d formed on the lower surface of layer 8. In a modified embodiment (Figs. 8 and 9, not shown), the layer 8 is formed of resistive material orthogonally grooved to form the separate resistors, the upper surfaces of which are metal coated to form the anodes. The thickness of the spacer layers 5 and 7 is such that the discharge initiating and sustaining voltages are lower and higher, respectively, between an anode and a starting electrode than between an anode and a cathode, whereby a discharge initiated between an anode and a starting electrode is automatically transferred to become a sustained anode-cathode discharge.

Abstract: 1,004,415. Road traffic measurements. DECCA Ltd. Sept. 12, 1961 [June 13, 1960], No. 45100/61. Divided out of 1,004,414. Heading G4Q. [Also in Division G1] Apparatus for providing an output representative of the mean speed of road traffic comprises means providing a first electrical output representing traffic congestion at a point, means providing a second electrical output representing rate of traffic flow at said point, and means responsive to said first and second outputs for determining the ratio between the congestion and the flow. As shown, Fig. 1, passage of a vehicle wheel over a pad 10 embedded in a road surface 11 closes contacts 12 in series with a power source 13 to produce a pulse of duration inversely proportional to the speed of the vehicle. A succession of such pulses is fed to an integrator 14 controlled by a timing device 15 to produce an output representing congestion which may operate an indicator 16 or be recorded or fed to a computer &c. The pulses are also normalized at 18 into pulses of uniform duration which are fed to a second integrator 19, also controlled by device 15, to produce an output representing rate of traffic flow, which may be indicated at 20 &c. The outputs from integrators 14, 19 are also supplied to a ratio determining device 21 which produces an output representing mean speed which is fed to indicator 22. In a modification, Fig. 2 (not shown), timing device 15 is rendered unnecessary by the use of leaky integrators comprising a high gain amplifier with an input resistor and a feedback circuit comprising a capacitor shunted by a high impedance resistor. Separate vehicle sensing elements may be used in different lanes of a road, and the pulses may be transmitted to remote integrators by modulation of a carrier frequency. Specification 1,004,413 also is referred to.
