Title: Improvements in or relating to voltage reference circuits
IPC: G05F3/18
Filed: 1957-07-03
Abstract: 828,646. Voltage measuring bridges. FERRANTI METERS Ltd., D., FLEMING, G. C., and BELSEY, F. H. Sept. 30, 1958 [July 3, 1957], No. 20983/57. Class 37. [Also in Group XL (c)] A bridge circuit has-resistors in one pair of opposite arms and one or more Zener diodes or like semi-conductor devices in each of the other pair of opposite arms, the diode or diodes in one arm being of opposite sign of temperature co-efficient from that of those in the other arm. In the circuit shown, as the voltage across terminals 9 and 10 increases, the current through the diagonal 5 increases until the zener diodes 3 and 4 begin to conduct when the diagonal current decreases to zero and then increases in the opposite direction. The diodes 3 are 4-volt diodes while the diodes 4 are 6-volt diodes, the two sets of diodes having opposite temperature co-efficients so that the voltage at which the current through the diagonal 5 is zero does not vary with temperature. A stepwise change in current through the diagonal may be obtained by suitably choosing the number of diodes in the arms of the bridge. The diagonal 5 may be constituted by a relay or may comprise a meter. In the latter case an open scale is obtained in the region where the current is reversing.

Abstract: 659,596. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Aug. 12, 1949, Nos. 21006 and 21007. Convention dates, Aug. 20, 1948 and Dec. 1, 1948. [Class 39 (i)] [Also in Group XL (b)] An image converter tube 74, Fig. 7, is employed in a circuit for comparing the intensity of corresponding points in successive frames a, b of film 68 in a television transmitter (see Group XL (b)), and comprises a photocathode 73 upon which is projected corresponding whole lines of the two frames. The resulting electron images are focused in the plane of two apertures 78, 79 by means of anode 76 and coil 75, and are scanned across the apertures by deflection coils 77. The diaphragm containing the apertures is connected to anode 76. Beyond the apertures are situated ring electrodes 80, 81 shielded from each other by partition 82. A source 83 of high frequency alternating voltage is connected to electrodes 80, 81 through a transformer 84, the centre tap 85 of which is returned to the same potential as the apertures. By this means, a potential sufficiently negative with respect to the apertures to cause them to be blocked is applied alternately to the electrodes 80, 81 and the electron beams thus allowed to pass in alternation to a multiplier section comprising a series of grids sensitized for a high secondary emission coefficient. An impedance 88 is connected to derive an output from the current collected at the final grid 86; the current being further amplified by secondary emission from a solid electrode 87. A storage cathode-ray tube 35, Fig. 4, is employed in the television receiver and comprises a storage target 40 of high insulation scanned under the control of electrodes 37, 38. The television video signal is applied to a mesh electrode 39 and controls the potentials to which the various portions of the target move by virtue of the loss of secondary electrons under the primary impart. The charge pattern stored on the target influences a photocathode mesh 41 illuminated 'by an intense source of light (not shown), and thereby controls the production of an electron image which, accelerated by anode 42 and focused by coil 36, results in a visible image on an aluminized fluorescent screen 44.
