Title: Colour television receiver
IPC: H04N9/66
Filed: 1955-08-17
Abstract: 783,022. Colour television. RADIO CORPORATION OF AMERICA. Aug. 17, 1955 [Sept. 14, 1954; Sept. 14, 1954], No. 23740/55. Addition to 780,389. Class 40 (3). A synchronous detector arrangement as described in the parent Specification, wherein the three colour-difference signals R-Y, B-Y and G-Y are derived by means of two synchronous detectors arranged to produce respectively both positive and negative versions of R-Y and B-Y and including a common coupling resistor across which is developed G-Y, is characterized in that the detectors each comprise an electric discharge tube including a control electrode, the chrominance sub-carrier being applied across the discharge tube and the locally-generated demodulating wave being applied to the control electrode. Fig. 4 shows such an arrangement, the synchronous detectors comprising triodes 53 and 73 with the chrominance sub-carrier applied individually to the anodes from secondary windings 43 and 45 of transformer 41. Locally-generated demodulating waves 47 and 67 of appropriate phases # 1  and # 2  (derived in practice from a tapped delay line, Fig. 5, not shown) are applied to the control grids via CR biasing networks 49, 54 and 69, 71. The phases are selected so that the signal R-Y is obtained at terminal 85 from across anode resistor 63, the signal B-Y is obtained at terminal 87 from across anode resistor 81, and the signal G-Y at terminal 86 as the combination -0.51 (R-Y) - 0.19(B-Y) appearing across the common cathode resistor 89. The triodes may be arranged to operate in class C, although reference is made to operation in a linear mode. Networks 65, 83 and 91 are provided to eliminate components at the subcarrier frequency. Due to interaction between the two detectors by reason of the common cathode resistor 89 it is necessary that the phases # 1  and # 2  of the demodulating waves should differ from the phase angles of the chrominance sub-carrier corresponding to R-Y and B-Y. In a typical design # 1  lags R-Y by 12.95 degrees and # 2  leads B-Y by 13.47 degrees. The amplitudes e 1  and e 2  of the sub-carrier waves applied to the anodes are in the ratio 1.41. According to a modification, Fig. 9 (not shown), interaction between the anode and grid signals in the two detectors due to interelectrode capacitances is neutralized by an additional capacitive coupling to the grids from the primary of the anode transformer supplying the chrominance sub-carrier. The Specification discusses the theory and design considerations of the invention at some length and also includes two complete colour receivers, Figs. 5 and 8 (not shown), incorporating the detector circuits. The detectors are arranged to operate at a high level whereby the output signals may be applied to modulate the display cathode-ray tube directly. Specification 774,441 is referred to.

Abstract: 391,843. Motor generators; automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, J. I.; 1338, Dean Street, Schenectady, New York, U.S.A.) Aug, 28, 1931, No. 24275. Convention date, Aug. 28, 1930. [Classes 35 and 38 (iv).] Induction machines.-Current transfer between two systems connected by a frequency-changing set is regulated by a generator cascaded with the asvnchronous machine of the set, the generator excitation being supplied by a transformer having two primary windings in opposition, one of which is fed in proportion to the primary current of the asynchronous machine. In the form shown, power may be transferred between systems 10 and 12, which are interlinked by synchronous and asynchronous machines 11, 14 respectively in either direction according to the position of the switch 34, and the amount transferred is regulated by the transformer secondary 36 which varies the voltage induced in the winding 40 of the transformer 31 provided with opposing primary windings 32, 33. The winding 40 feeds through a frequency changer 29 the exciting winding 27 of the exciter 21 for the regulating machine 17. The exciter 21 has an additional exciting winding 24 which minimizes fluctuations of the power transferred when a change of frequency occurs. The machines 14 and 29 have the same number of poles. By connecting the machine 21 direct to the machine 14, machine 17 may be omitted, or alternatively, a single machine with its slip rings connected to the transformer winding 40, and coupled to the main machine may be used in place of machines 17, 21, 29 ; this machine would have the same number of poles as the asynchronous machine 14, and would have rotary and stationary exciting windings to perform the functions of windings 27, 24 in the Figure. The Specification as open to inspection under Sect. 91 comprises also arrangements wherein the machine 14 may drive a load, such as a fan, and it is stated that the invention may be applied to the control of the current in any circuit; thus, instead of a machine 15 there may be in series with winding 32 any alternating-current circuit, the current of which is to be controlled. The transformer may be replaced by any equivalent voltage-producing means. This subject-matter does not appear in the Specification as accepted.
