Title: Electronic circuit for use with an apparatus for detecting mobile impurities in a transparent liquid
IPC: G01N33/00
Filed: 1974-07-09
Abstract: 1473693 Pulse discriminating EISAI CO Ltd 9 July 1974 [9 July 1973] 30417/74 Heading H3P [Also in Division G1] The invention relates to a circuit, for a photoelectric detector, arranged to remove regularly occurring pulses from a sequence of regularly and irregularly occurring pulses. As applied to an arrangement for detection of foreign matter in a clear liquid contained in an ampoule, which itself, bears a mark on its surface, on rotating the ampoule at high speed and then stopping it suddenly, the solid matter is caused to float up within the ampoule and can be detected by reflection or obstruction of light by a scanning detector. The foreign matter is represented by irregularly occurring pulses in the detector output, from which the regularly occurring pulses due to the mark on the ampoule are to be removed. The detector is suitably a scanning-type photodiode array or an optical fibre scanning device. In a simplified situation in which one regular pulse a (due to a mark on the ampoule) occurs during each scan of a four-scan cycle, and the pulses due to foreign matter b, c, d occur at different times in the consecutive scans, the circuit of Fig. 1 is used to remove the pulses a. Comparator 1 removes any pulses from detector A output (Fig. 2) below a threshold level L (Fig. 3) and the pulses occurring at its output during three scanning frames I, II, III are stored in shift register 3 by virtue of a feedback loop to OR gate 2 at the input to the register, Fig. 4. The shift register 3 output and the comparator 1 output are combined in AND-gate 4 to pass only the regular pulses a, Fig. 5, to be stored in shift register 6, which is also provided with a feedback loop and input OR-gate (5). By use of an Exclusive-OR gate 7 the pulse a is finally removed to pass only the foreign matter pulses, Fig. 6, to utilization point B. To ensure removal of regular pulses when these are often below the level L and may occur only once in a scanning cycle, a further circuit as in Fig. 1 with a lower threshold level set in its comparator is used, and the outputs of the Exclusive-OR gates of these circuits combined at and AND gate. A further AND gate can be used to gate only the last scan of a scan cycle.

Abstract: 1467182 Gas discharge display panels BURROUGHS CORP 16 July 1974 [26 Dec 1973] 31369/74 Heading H1D A flat panel for displaying bars of light comprises a gas-filled envelope including a base-plate 20 and a transparent face plate 30 spaced apart and sealed at the edges, parallel linear cathodes 50A, 50B, 50C on the surface of base-plate 20 nearer face plate 30, an anode 90 mounted between the plates in operative relation to the cathodes, and means for electrically energizing the anode as the cathodes are energized. As shown in Figs. 1, 2, the display panel consists of a base-plate 20 carrying an opaque insulating layer 44 and sealed to a tray-like glass face plate 30. Closely spaced lines 50A, 50B, 50C are formed of conductive material on layer 44 in the order shown. All lines 50A, 50C are connected to conductors 60A, 60C. An insulating layer 80 is formed over conductor 60A, and a conductor 60B on the layer is connected to lines 50B through apertures 84. Another insulating layer 83 is formed over conductor 60C. The conductors 60A, 60B, 60C terminate in pads 70A, 70B, 70C. The conductors 50A, 50B, 50C are also partially covered by layers 80, 83, but portions of the conductors are visible between the layers. A reset line 50R at the end at the array of conductors is connected to a pad 70R, and a keep-alive cell comprises electrodes 50KA and 50KK connected to pads 60KA, 60KK connected to a power source V, which maintains a supply of ions. The reset line 50R and the keep-alive cell may be screened from view. The enclosed space is filled with, e.g. pure Ne, or Ne with 0À2% Xe, at 400 Torr. To operate the display, a ramp control voltage from a source 120, and an analogue signal from a source 100 are applied to a differential amplifier 110, the output of which is connected to anode 90. Cathode drivers 130A, 130B, 130C are connected to pads 70A, 70B, 70C, and a reset cathode driver 130D to pad 70R. In operation, the reset conductor 50R is first energized, and if the anode 90 is energized a discharge is established. Next, the adjacent conductor 50A is energized and, since ions are present in the discharge from the adjacent reset conductor 50R, a discharge from conductor 50A is established. Meanwhile the ramp control voltage is increasing. As long as it is less than the analogue signal, there is an output from the differential amplifier 110 to provide a voltage to the anode. The conductors 50 give rise to discharges in succession until the ramp control voltage equals the analogue signal, so that the discharges are quenched. As the reset conductor 50R is operated at rapidly recurring intervals, a band or column of light appears, the length of which changes with the analogue signal. In a modification (Fig. 3, not not shown) two parts of each conductor visible, with two anodes.
