Title: Barium zirconium borate, pigments containing the same, and processes for their production
IPC: C09C1/00
Filed: 1961-07-12
Abstract: A white barium zirconium borate pigment BaO.ZrO2.B2O3 is prepared by heating a mixture of either (1) zirconium dioxide and barium metaborate or compounds convertible to such upon heating, e.g. zirconium sulphate tetrahydrate and barium sulphide, carbonate or hydroxide with boron trioxide or boric acid, or (2) barium metazirconate and boron trioxide or a boron compound convertible to the trioxide upon heating. The heating is preferably carried out between 800 DEG -1300 DEG C. for 10 mins.-24 hours. The zirconium dioxide used may be either the mineral baddeleyite or it may be prepared by precipitation in the hydrous form from zirconium sulphate tetrahydrate or zirconium tetrachloride solutions. The zirconium sulphate tetrahydrate may be prepared by recrystallizing precipitated basic zirconium sulphate from sulphuric acid. The barium metaborate used may be precipitated by reacting solutions of barium sulphide or hydroxide with sodium tetraborate. Example 1 refers to the above stoichiometric quantities of barium carbonate, boric acid and zirconium dioxide being mixed in a mortar and pestle and fired at 1050 DEG C. for one hour after which the cooled product was reground and fired for a further hour at 1050 DEG C. X-ray analysis of the resulting crystalline product indicated that a compound had been formed. Example 2 refers to a ground mixture of barium carbonate, boric acid and recrystallized zirconium sulphate tetrahydrate being fired at 1100 DEG C., reground p and refired at 1100 DEG C. for a further half hour. Example 3 refers to hydrous zirconium dioxide being precipitated from zirconium sulphate tetrahydrate solution with sodium hydroxide. A slurry of the hydrous zirconium dioxide and boric acid was then gently refluxed and barium hydroxide added and the refluxing continued for two hours. The resulting wet cake was dried at 140 DEG C. and fired as in Example 1. Example 4 refers to the barium zirconium borate compound being prepared together with excess barium metaborate. Example 5 refers to the barium zirconium borate compound being prepared together with excess zirconium dioxide. Specifications 813,228 and 879,499 are referred to.

Patent ES-354359-A1 (ES)
Title: Automatic chroma control circuit
IPC: H04N9/68
Filed: 1968-05-27
Abstract: An automatic chroma control (ACC) circuit for a colour TV receiver comprises means for deriving D.C. voltage components from the input and output of a colour-synchronizing- burst gate amplifier and means for controlling the gain of a chrominance amplifier in response to a predetermined combination of the said voltage components. The voltage component from the output of the burst gate amplifier is in practice derived at the grid of a phase locked colour reference oscillator to which the burst signals are applied via a narrow band filter which incidently removes any noise signals. Noise voltages present at the input to the burst gate amplifier, however, are rectified by the grid-cathode diode and produce a negative bias voltage which reduces the gain of the burst gate amplifier. The resulting reduction in the amplitude of the burst voltage applied to the oscillator causes the ACC circuit to increase the gain of the chrominance amplifier and produces an undesired increase in the signals applied to the colour demodulator. This error is minimized by applying the noise generated D.C. voltage component at the input to the burst gate amplifier to the ACC circuit to offset the variation in the voltage derived at the output of the burst gate oscillator. In a first embodiment, Fig. 1, a closed loop ACC arrangement identical to that described in Specification 1,198,207 in which a D.C. voltage component appearing at the grid of a colour reference oscillator 18 is applied via resistor 132 to an ACC circuit 28 comprising a currentcontrolled amplifier the output of which is applied as bias to a chrominance amplifier 12, is modified by connecting the earthy-end of the grid-leak resistor 94 of the burst gate amplifier 14 to the input of the current controlled amplifier. Grid-leak resistor 49 may be selected in value so that the increase in current flowing through it from an increased negative D.C. voltage component at the grid of the burst gate amplifier 14 due to noise compensates for the reduction in the current in grid-leak resistor 132 due to the resulting decrease in the amplitude of the burst signals applied to the oscillator. A second embodiment, Fig. 2 (not shown), comprises an open loop ACC arrangement in which the chrominance amplifier (12) is outside the ACC loop. The grid-leaks of the burst gate amplifier (14) and the reference oscillator (18) are connected directly to ground and the D.C. voltage components at the grids of these valves are applied to the input of a voltage amplifier which provides a bias voltage to control the gain of the chrominance amplifier (12).

Title: Phase locked oscillators
IPC: G01S5/10
Filed: 1970-08-31
Abstract: A phase locked oscillator comprises an oscillator unit 12 having an output changeable between two frequencies, a phase comparator 16 and an integrator 20, an arrangement 22, 23 and 25 for producing an oscillator control pulse signal whose pulse period is greater than the cycle period of the oscillator output and having a pulse duration linearly proportional to the amplitude of the integrated phase error signal and a further arrangement 13 for changing the oscillator output between its two frequencies so that the average frequency is maintained at the required value for phase lock e.g. for an intermittent or noisy signal. The oscillator control signal may have a rectangular or triangular waveform with a repetition period over 10 times the oscillator cycle period and the overall phase shift is less than 30. The frequency control pulses may be produced by a linear timing generator (Fig. 3) comprising a constant current generator (34) charging a capacitor (33) and a monostable pulse generator (31, 32), the two generators being controlled by clock pulses (at 35) from a source 23 determining the pulse repetition period. An electronic switch comprising an F.E.T. (36) is provided for switching a capacitor in the oscillator circuit. The timing generator comprises a constant current generator 34 charging a capacitor 33 to a magnitude dependent on input amplitude from transistor 30 or to a fixed voltage at a current rate dependent on input amplitude. A clock pulse applied at 35 initiates charging and determines the pulse repetition period of the monostable circuit 31, 32. The pulse duration and hence the mark-space ratio are dependent on the input amplitude 30. The output pulse is used to switch capacitor 37 in or out of circuit by an F.E.T. switch 36.
