Title: Colour television signal reproducing system

Filed: 1971-05-12
Abstract: 1352772 Colour television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 12 May 1971 [13 May 1970] 14554/71 Heading H4F Timing errors in the chrominance signal of a colour television signal recovered from a magnetic recording are reduced by frequency multiplying at 8 the horizontal sync. signals separated from the recovered signal and frequency subtracting the resulting signal from the chrominance signal at 9 to produce a chrominance signal of lower frequency and smaller timing errors, which is frequency added at 10 to the output signal of a fixed frequency oscillator 11. The remaining timing errors may be removed by using an automatic phase control circuit 14 to produce a continuous output locked in phase and frequency to the input bursts. In an alternative embodiment (Fig. 4, not shown) the horizontal sync. signals are frequency multiplied to have a frequency equal to that of the chrominance subcarrier, this frequency multiplied signal then being frequency subtracted from the output of a fixed oscillator, the resultant signal being frequency added to the chrominance signal to give a chrominance signal with a subcarrier frequency equal to the frequency of the fixed oscillator and no timing errors.

As shown in Figs. 1 and 14 the ring 33 is disposed in the tuning cavity 15 of an electron tube 10 operating as an amplifier. The position of ring 33 is adjusted to a position of maximum in the magnetic field associated with the TE 11  mode by means of rods 38 which slide through corresponding openings in the piston 26 and are assembled to the ring 33 by means of holes 37. The ring 33 comprises an external cylindrical rim 34 provided with circular apertures 39 of diameter approximately #/10 (#= wavelength of unwanted mode) and an annular ring 35 provided with a series of circumferential slots the lengths of which are just less than #/2. The outer diameter of the structure 33 is just smaller than the internal diameter of cavity 15 and in certain of the apertures 39 in rin 34 insulating plugs may be inserted to act as spacers. The ring is preferably of a ferromagnetic alloy or may be nickel-plated copper such that the ring 33 is resistive at high frequencies because of the skin effect. The suppressor device as stated may be alternatively disposed in the grid-cathode cavity 14 or in each cavity 14 and 15.

Abstract: 702,370. Treating liquids with gases. FARBENFABRIKEN BAYER. June 11, 1952 [July 2, 1951], No. 14762/52. Class 55 (2) In treating liquids with gases or vapours particularly absorbing sulphur trioxide gas in sulphuric acid, cooling the hot acid with air and washing the waste gases with acid, liquid is raised by gas under pressure through upright or inclined tubes extending above the liquid level in a horizontal or inclined container or duct through the upper part of which gas flows from end to end, the liquid running down again transversely to the direction of flow of the gas into the body of liquid. In a trough 1 with a cover 2 and inlets and outlets 3g for gas and 3f for liquid, rising pipes 4 carrying preferably staggered discs 6 are supported on a grating 5. Six different ways shown of introducing gas into the pipes comprise injector nozzles 9 for the pressure medium, a gas manifold 8a and enlarged lower portions of the pipes with serrated edges, and depending gas pipes 9c ... f. The pipes 9d are supplied with gas withdrawn from the trough and blown back by injectors 15d. Gas for pipes 9e, 9f, is kept separate from gas in the trough, being blown through a manifold 23 and withdrawn after emerging from the rising pipes through a compartment 16. Deflectors 7, 7a ... d for the liquid at the pipe outlets may be provided, and partitions 24 forming imperfect seals may subdivide the bath in the direction of flow to check intermixing of liquid at different stages of treatment. In modifications the rising pipes in a brick-lined trough or tube stand on bricks &c. and are spaced by short tubes. A trough cover may include an internal lining of glass pipes spaced from it by a layer of glass wool. For treatment above or below atmospheric pressure several containers may be superposed liquid flowing successively therethrough preferably inside an upright tube. Steam coils &c. may operate the pressure release by evaporating part of the liquid and cooled coils may be included for condensing surplus vapour.
