Abstract: 717,267. Television. GENERAL ELECTRIC CO., Ltd., BARRY, J. N., PRICE, J. R., and GRIFFITH, G W. S. March 20, 1953 [April 1, 1952], No. 8289/52. Class 40 (3) Positive going television signals are applied through a capacitor 3 of low value to a stage 4 having a high input impedance and are restored to fixed level by means of a diode 8 rendered conducting during the black-level interval following each synchronizing signal. The diode is connected to the cathode of a normally-conducting pentode 6 which is cut off by control pulses applied to its grid so as to bring the diode cathode to earth potential and allow it to conduct. If desired restoration may be effected to a potential positive with respect to earth by connecting a resistor between the cathode of pentode 6 and the positive supply line. The control pulses are derived by differentiating in circuit 11, 12 negative going synchronizing signals applied to 10, selecting on!y the resulting positive going pulses by the biasing of pentode 13, and then repeating the process in circuit 19, 20 and pentode 21 to obtain finally pulses occurring during the blacklevel intervals. Diode 16 functions as a pulse limiter. In an alternative arrangement the second differentiating circuit 19, 20 and pentode 21 may be replaced by a de'ay line. It is stated that stage 4 having a high input impedance (a cathodefollower as shown) may be a cathode-ray tube.

Title: Apparatus suitable for use in mixing and dispensing a multi- constituent composition
IPC: B29C48/92
Filed: 1974-02-25
Abstract: 1458701 Automatic control BRITISH UNITED SHOE MACHINERY CO Ltd 25 Feb 1974 [26 Feb 1973] 8354/74 Heading G3N Mixing apparatus includes a chamber receiving supplies of first and second constituents. The quantities of each constituent fed to the chamber during a given cycle are metered, and the feed rate of one of the constituents is adjusted to maintain a desired ratio between the quantities of the constituents in the chamber. As shown, a chamber 10 receives polyhydroxyl material from a dispenser 46 and isocyanate from a dispenser 48 through respective valves 23, 25. Polyurethane is produced in the chamber and is forced by a piston 14 into a mould 34. At the beginning of an operating cycle, the chamber contains an excess of polyhydroxyl to quench the reaction. Isocyanate is therefore supplied to the chamber until the desired ratio is reached, whereupon both constituents are supplied simultaneously to maintain the ratio until a required total volume of mixture is present in the chamber. A stirrer 30 mixes the constituents before evacuation into the mould 34. The total amount of isocyanate fed to the chamber is metered by a transducer 68 connected to a dispensing piston-rod 60. Similarly, a transducer 67 meters the amount of polyhydroxyl which has been supplied, and signals from the two transducers are added and compared in a circuit 72 with a signal from a potentiometer 73 representing the required total volume. Thus circuit 72 supplies a signal to main controller 20 when the chamber 10 has been fed to capacity. A further transducer 66 also meters the amount of the polyhydroxyl fed, but provides an output signal modified by a desired constituent ratio voltage set on a potentiometer 76. A circuit 74 compares this modified signal with the signal from transducer 68 to form an error signal which is supplied through a circuit 82 to main controller 20 which accordingly adjusts the isocyanate feed to maintain the desired ratio. The error signal is also supplied to a zero detector circuit 80 which provides an input to the main controller 20 when the desired ratio is obtained, indicating that the mixture in the chamber 10 is suitable for ejection into the mould when required.
