Filed: 1974-05-07
Abstract: 1473531 Quadraphonic systems D H COOPER 7 May 1974 [10 May 1973] 20051/74 Heading H4R In a quadraphonic recording system where each groove wall is recorded with a base band signal and an angle modulated sub carrier signal, cross talk from the base band signal to the sub carrier signal which is caused by tracing distortion during record reproduction is cancelled by introducing into the sub carrier modulation a proportion of the base band signal, the proportion being dependent on the groove position on the recorded disc. As described the system is a modification of acknowledged prior art of Fig. 1 (not shown) in which the two base band signals TL and TR and two signals TT and TQ modulated on a sub carriers are related to the left front SLF, right front SRF, left back SLB and right back SRB signals by the relations As shown in Fig. 8 the base band signals are as in the prior art and the two signals to angle modulate the sub-carriers are TT+kTQ and TT-kTQ, where TT and TQ are as set out above and k is preferably 0À33. The sub carrier signals are passed through an equalizer, of characteristic similar to the R1AA characteristic as described in Specification 1,473,532, before having a proportion of the respective base band signal added thereto. The resulting composite signals angle modulate respective carriers before being added to the respective base band signals and application to the recording cutter amplifier 7. The proportion of the base band signal added to the sub carrier signal is dependent on the recording cutter position on the record disc and the stylus tip radius and follows the relation m= (rvw/S<SP>2</SP>) where m is the gain index of the base band signal; r the stylus tip radius; w is the carrier frequency; v the peak velocity of the main channel signal; and S the stylus velocity in the groove = #DN/60 where D is the groove diameter and N is the record speed in r.p.m.

Title: Improvements in or relating to television reproducer tubes
IPC: H01J29/89
Filed: 1939-07-12
Abstract: 531,760. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MYERS, L. M. July 12, 1939, No. 20347. [Class 39 (i)] To obtain a large bright image in television reproduction a secondary emitting electrode CS is scanned by a modulated ray, the emitted electrons being projected on an incandescing anode A to give the picture; the secondary cathode is of mosaic form, the discrete elements being of insulating material. A second unmodulated beam may scan the mosaic in front of the other ray to bring the elements to a datum potential, but this may be effected by leakage ; the wipe out beam may give a secondary emissive ratio of less than unity. The anode is carried on a quartz plate, which closes the end of a cylinder P of aluminium, copper or brass, this cylinder connecting with a copper focusing chamber F which in turn is an extension of the cathode chamber C. The chambers F and C are separated by an insulator I<SP>1</SP> of quartz or porcelain; the three chambers are continuously evacuated through the pipe T. The anode A may be independently heated nearly up to incandescing temperature ; it is held by thin radial supports s. A mirror MM is supported by the back metal wall M. A magnet coil L focuses the secondary electrons on to the anode. The secondary electrode CS is concave with discrete insulating areas lightly covered with barium. It may be formed by sputtering sapphire through a fine mesh screen on to a massive metal base; or magnesium or tungsten may be smoked on. Barium is coated on the areas and it may connect them lightly to provide leakage paths. In a further method an insulating powder which will stand heat is first fixed on the metal base ; barium, oxide or azide is sprinkled on and after introduction into the tube, the cathode is heated and scanned, this destroying any barium. The electrode CS may be independently heated. The wall of the chamber F may be made of lengths of metal tube mt, Fig. 3, separated by insulation, to form an electrostatic lens. The projection chamber P may be water cooled. Low pressure waxes or bitumens may be used at joints where brazing is not possible, the chambers being held together by clamps and insulated screws. Potentials of the electrodes are given in the description by way of example.
