Title: Improvements relating to cathode-ray tubes for television
IPC: H01J29/46
Filed: 1933-06-26
Abstract: 421,603. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. June 26, 1933, Nos. 18120 and 18121. Convention dates, June 27, 1932 and Aug. 12, 1932. [Classes 39 (i) and 40 (iii)] Distortion due to current between a cathoderay and deflecting-plates is eliminated (a) by reducing the resistance of the circuit of the deflecting plates to such a value that the potential developed across it by the leakage current is less than 1 per cent of the maximum deflection potential, or (b) by making the potential of the deflecting plates at most equal to that of the cathode rays, or (c) by placing in front of the deflecting plates 2 an openwork screening grid 11, which may be cylindrical or flat and negatively biassed or conductively connected to the earthed deflecting-plate. When a diaphragm with a negative potential relatively to the anode is provided between the two pairs of deflecting-plates, Fig. 5, the diaphragm is so dimensioned that in the position of maximum deflection the ray is still sufficiently away from the edge to avoid edge field distortion. To avoid image-form distortion from differential deflecting-action by the second pair of deflecting plates 33, 34, due to the ray leaving the first pair at speeds varying with the deflection, the second pair of plates are tilted. The Specification as open to inspection under Sect. 91 describes also energizing the deflecting- plates in opposite phase. This subject-matter does not appear in the Specification as accepted.

Abstract: 630,230. Electric heating; thermal image. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and WADDICOR, H. July 9, 1947, No. 18165. [Class 39(iii)] [Also in Group XXXVIII] To measure the conductor temperature in a multicore cable under working conditions, the temperature of the filler at the centre of the cable is measured by a pair of wires embedded therein, and the small temperature difference between the filler and the conductors is measured in a sample length of similarly loaded cable, and added to the first measurement. The copper wires 5 embedded in the cable 1 form a resistance thermometer connected in one arm of a bridge circuit, with compensating leads 9 in the other arm, so that the out-of-balance voltage developed in the coil 11 of the indicator depends on the temperature of the filler. Some of the strands of the cores of the sample cable 13 are replaced by high resistance wire and connected in series to a current transformed 18 round one of the cores of the main cable so that the sample is loaded to the same watts/foot as the main cable. Two thermocouples 20, 21 placed respectively at the centre of the sample, and on the surface of one of the conductors are connected in series opposition to the second coil 19 of the indicator.

Filed: 1947-07-15
Abstract: 639,577. Turns-sensitive apparatus. SPERRY GYROSCOPE CO., Inc. July 15, 1947, No. 18829. Convention date, Aug. 2, 1946. [Class 97 (iii.)] [Also in Group XXXVIII] In stable reference apparatus of the kind in which a stretched wire 11 is maintained at its natural frequency in a direction at right angles to a magnetic field, e.g. the horizontal component of the earth's field, the vibration takes place in the field of a pair of coils 21, 23 supplied by a high-frequency generator 33, but normally in the plane containing or parallel to the axis of the coils. If, however, the direction of the axis changes, the plane of vibration remains the same and a current is induced in the wire at the high frequency modulated at the frequency of vibration, and is used to drive a servomotor 69 which restores the normal direction of the axis, at the same time driving an indicator disc 17. As shown, the coils 21, 23 are supplied at 60 kc. and a further pair 25, 27 at right angles to the pair 21, 23 are supplied at 50 kc. Under normal conditions there is thus induced in the wire a 50 kc. current modulated at the natural frequency of the wire 11. This current after amplification is demodulated at 55, and fed back via an amplitude limiter 59 to the wire to keep it in vibration. A portion is passed on to provide the reference phase for a phase sensitive rectifier 65 feeding a D.C. motor 69. The modulated 60 kc. output when present is similarly amplified and demodulated and passed to the input of the rectifier 65. Instead of providing connections from the 50 kc. and 60 kc. generators to the demodulators, unmodulated high frequency components may be included in the current in the vibrating wire by mounting the wire so that it does not, when stationary, pass through the axis of either pair of coils. Specifications 600,165, 601,051,:610,530 and 647,895 are referred to.
