Title: Automatic Chroma Control Circuit
Inventor: YONGUE JAMES MCINTIRE
IPC: H03G3/22
Filed: 1968-05-29
Abstract: 1,198,207. Television. R.C.A. CORPORATION. 29 May, 1968 [29 May, 19671, No. 25643/68. Heading H4F. An automatic chroma control (ACC) circuit for a colour television receiver comprises a current controlled amplifier an interelectrode path of which forms part of a grid leak of an oscillator, and the output of the current controlled amplifier being D.C. coupled to a controllable gain chrominance amplifier the output of which is itself coupled to the oscillator. As shown, the second detector output of the receiver is applied to a driver amplifier 10 which provides inputs for the AGC and deflection systems 16 and 11 and for the chrominance amplifier 12 tuned to the subcarrier frequency. The output of amplifier 12 is applied to the colour detection circuits 20 and to a colour synchronization burst gate amplifier 14 which is keyed by pulses from the deflection systems 11. The output of the burst gate amplifier 14 is used to phase lock a crystal controlled colour reference oscillator 18. The grid-leak resistor 132 of the oscillator 18 is connected to the emitter of a grounded-base transistor amplifier 28 the collector voltage of which is level shifted and applied as ACC bias to the grid of the chrominance amplifier 12. The level shifting circuit comprises a potential divider 146, 148 the lower end of which is connected to a source of negative potential obtained, in this case, from the grid of a keyed burst blanking triode 26. In the absence of colour burst signals a D.C. voltage component is produced at the grid of oscillator 18 due to rectification by the gridcathode diode. The resultant current through resistor 132 produces a voltage at the collector of ACC amplifier 28 which after level shifting is applied as a small negative bias to the chrominance amplifier 12 which is thus arranged for maximum gain. As the amplitude of burst signals applied to the oscillator increases the rectified grid voltage of the oscillator becomes more negative and results in a decreased positive voltage at the collector of the ACC amplifier and hence an increased negative bias is applied to the chrominance amplifier 12 to reduce its gain.

Title: Improvements in the manufacture of sugar
IPC: C13B30/02
Filed: 1927-09-29
Abstract: 294,800. Varnau, B. H., and Wayne, T. B. Sept. 29, 1927. Refining sugar.- Relates to a method of obtaining fine grained, soft cane sugar of high purity from the syrups remaining after the purging of hard, granulated massecuites without reboiling these syrups in vacuum pans. The syrup is first heated to remove any false grain, sufficiently small crystals are then induced by cooling the syrup rapidly, with or without the addition of seed crystals of the required kind, and finally, the mass is kept in slow, continuous agitation during crystallization. In an example of the method, syrup from a centrifuge 20, in which a hard granulated massecuite has been treated, is separated from the wash water by means of a tilting device. This syrup contains 78 to 82 per cent of solids at a temperature of between 140‹ and 165‹ F., and is passed to a receiving tank 21 from which it is delivered by a pump 24 to a heater 26, or by a valved bye-pass to an equalizing tank 27, or direct to a water jacketed cooler 30. Preferably, the temperature is first raised to between 140‹ and 180‹ F. to dissolve any false grain, after which the syrup passes on to the quickly revolving scatter plate 32 of a centrifugal basket 31 in the cooler, whereby it is thrown in a finely divided condition on to the walls of the cooler, whence it is delivered at a temperature of from 95‹ to 130‹ F. to the crystallizer 38 where it is kept in a state of agitation by a stirrer 39. A current of air may be drawn through the cooler by a fan 34. The syrup may 'be treated with seed crystals, or with one to ten per cent of a magma containing the desired crystals, just be. fore admission to the cooler. By means of water circulated round the crystallizer, the temperature is kept between 90‹ and 100‹ F. and, after satisfactory crystallization is assured, the temperature may be further lowered. From the crystallizer the massecuite passes to a mixer 41 and then to a centrifuge 42 from which the mother liquor passes to storage tanks 47, 49. From these tanks the liquor may pass to vacuum pans 15, 16 or to a char filter 53 prior to further treatment. The granulated sugar separated by the centrifuge 42 is washed with water and is stated to be of a high purityand to pass a 35 to 40 mesh screen.

Filed: 1925-10-15
Abstract: 264,239. Im Thurm, J. K., and Alder, L. S. B. Oct. 15, 1925. Frequency, inductances, and capacities, measuring.-The resonant frequency of a circuit 15, Fig. 1, is determined by means of an oscillation-generating circuit 5 and a resonating circuit 1 comprising an inductance 2, variable condenser 4, and switch 3 in series. The circuit 5 comprises an inductance 6 and variable condenser 7 and is connected through a variable condenser 8 shunted by an inductance 9 between the grid and filament of a valve 10. The anode of the valve 10 is connected through a reaction coil 11 and a telephone receiver 12 to the high-tension battery 13. The telephone receiver and battery are shunted by a condenser 14. The shunted condenser 8 is adjusted until a steady quench note is heard in the telephones. The circuit 5 is brought into resonance with the circuit 15 by adjusting the variable condenser 7 until a sudden rise in the pitch rise in the pitch of the quench note takes place. The frequencies may then be found from the calibration of the circuit 5, or the switch 3 may be closed and the condenser 4 of the resonator varied until a further rise of pitch occurs, indicating that the resonator 1 is in tune with the circuit 15. The frequency is then found from the calibration of the resonator. A modification for determining the resonant frequency of a receiving circuit 17 is shown in Fig. 2. The exciting circuit 16 is provided with an oscillating circuit 5, 6, 7, a condenser 19 between the anode of the valve 10 and the oscillating circuit 5, and an inductance 20 between the hightension battery 13 and the anode of the valve 10. A variable condenser 21 in parallel with a choking coil 22 is connected between a point of the inductance 6 and the filament of the valve 10. For tuning the circuit 17, the resonator 1 is adjusted to the required wavelength and the exciter is tuned by adjusting the condenser 7 until a rise in pitch of the quench note occurs. The receiver circuits are then adjusted in turn, each giving a further rise in pitch of the quench note. The resonator 1, instead of comprising a condenser and inductance may consist of a piezoelectric crytal or other system capable of being thrown into oscillation at predetermined frequencies by an oscillating electric or magnetic field. The invention is also applicable for measuring capacities, inductances, or capacityinductance products.
