Abstract: 692,984. Saw-tooth generating circuits. EDISON SWAN ELECTRIC CO., Ltd. March 24, 1952 [March 28, 1951], No. 7539/52. Class 40 (vi). In a saw-tooth generator of the type in which a condenser is charged through a resistor and discharged through a valve arranged in an oscillatory circuit whereby it conducts once per cycle of oscillation, one side of the valve discharge circuit is connected to a variable tap on the charging resistor whereby the resistance in the discharge path may be varied without appreciably varying the anode load of the valve. A condenser 12 is charged through resistors 13, 15 and 16 and discharged periodically through a valve 4 arranged in a Class C Hartley oscillator circuit. The portion of resistor 14 included in the discharge path may be varied to vary the " negative peaking without appreciably varying the anode load since if the branch of the load between the tap 15 and the H.T. supply is increased the branch between 15 and earth is decreased. Variations in frequency and the negative voltage obtained from the grid due to such changes in load are thus avoided. The output wave is suitable for driving an amplifier feeding deflection coils of a cathode-ray tube.

The wheel 14 engages at the top the bevel wheel 16 fastened on the tube 6 and at the bottom the bevel whee 17 fastened on the tube 8 whilst the wheel 15 similarly engages the wheel 18 fastened on the tube 8 and the wheel 19 fastened on the tube 9. The arrangement is such that when the tube 8 is rotated through an angle a the tube 7 is rotated through an angle alpha/2 and the apparent direction of the element 4 turned through an angle a, the tube 9 remaining fixed relative to the tube 6. Adjustably secured to the tube 9 is a ring 22 carrying the index finger 25 and a total reflection prism 24 having a series of parallel straight lines marked on its internal face. In use the tube 8 is rotated until the apparent direction of the element 4 coincides with the lines on the prism 24, the angle being read off from a graduated circle 20 adjustably secured to the tube 8 and co-operating with the index 25. In a modification the compass box is provided with an annular expansion compensating chamber and has at the bottom a toothed wheel connected by pinions to a coaxial toothed wheel of double the diameter mounted on the tube carrying the Amici prism. The pinions are mounted on an outer coaxial tube adjustably attached to the support and carrying at the bottom the total reflecting prism 24 and at its top the index finger 25. In use the apparent direction of the magnetic element is reduced to zero by turning the compass box, the tube carrying the Amici prism being turned through half the angle, and the reading being. obtained from a graduated circle adjustably secured to the compass box and co-operating with the index 25. In a further modification the magnetic element is illuminated by a lamp and placed at the bottom of a vertical cylindrical tube inside which is located a tube carrying the Amici prism and rotatable by a tangent screw. At the top of the outer tube is a total reflection prism adapted to reflect the image along a funnel on to the translucent face of a plano-convex lens, which is rotatable in its seat and provided with reference lines. The Amici prism may be replaced by a compound system of Amici prisms. A scale graduated empirically to give readings independent of the usual compass errors may be provided on the graduated circle.

Title: Device for demagnetizing television picture tubes
IPC: H01J29/00
Filed: 1967-02-17
Abstract: 1,110,926. Cathode-ray tube apparatus. COMPAGNIE FRANCAIS DE TELEVISION. 17 Feb., 1967 [25 Feb., 1966; 26 Jan., 1967], No. 7815/67. Heading H4T. In an arrangement for demagnetizing metallic parts inside or in the vicinity of a television picture tube by the action of a damped alternating current flowing in a demagnetizing coil the duration of the demagnetizing process is arranged to occupy a time not exceeding the duration of one field period and the process, which is initiated when the apparatus is switched on is repeated periodically. The duration of the demagnetizing process is preferably of the order of five milliseconds and the period of repetition is at least equal to five seconds and preferably between fifteen seconds and one minute. In carrying out the invention the demagnetizing coil 95 (Fig. 3) in series with a resistor 97 is, at the commencement of each demagnetizing process, connected to a capacitor 96, previously charged via resistor 94 from source 92, by switch means 91 operated by relay coil 88. The latter is supplied with pulses from a multivibrator of the desired repetition period triggered by the field synchronizing signals so that each demagnetizing process commences at the beginning of a field period and the constants of the elements 95, 96 and 97 are so chosen that the current in coil 95 decays to a negligible value so as to effect the demagnetizing process in the required time. In addition, the multivibrator is arranged to trigger a further multivibrator which supplies a pulse utilized to blank the tube beam for one field period to prevent visible distortion since the demagnetizing process overlaps the normal blanking period and extends into the active field period.
