Title: Improvements in or relating to apparatus for use with cathode ray tubes
IPC: H04N5/208
Filed: 1950-05-26
Abstract: 686,327. Television. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. May 28, 1951 [May 26, 1950], No. 13359/50. Class 40 (iii). In a television receiver, the sharpness of the reproduced image is increased by applying the video signal to reduce the velocity of line scan when a sudden change in picture intensity occurs. As shown, the last video stage 5 has a cathode and an anode load so as to produce both a positive and a negative output. These video signals are fed to differentiating circuits 12, 13 and thence to the anodes of a double diode 14. When there is a sudden change in picture information from black to white one diode conducts and when the change is from white to black the other diode conducts. In either case a positive pulse appears across C.R. circuit 17, 18. This pulse is then fed to the grid of the oscillator valve (not shown) in the line scanning generator so that the speed of line scan is momentarily almost halted. The time constant of C.R. circuit 17, 18, is appreciably loss than the time of a single line scan. If the cathode-ray tube is arranged for magnetic deflection, separate line deflection coils may be used to effect the reduction in the speed of scanning.

Abstract: <PICT:0983713/C6-C7/1> <PICT:0983713/C6-C7/2> <PICT:0983713/C6-C7/3> In apparatus for the preparation of brewers' malt wherein at least one of the steeping, germination and curing treatments of the cereal is effected in treatment chambers in a treatment shaft through which the cereal passes by gravity, the rate at which the cereal passes through the chambers is controlled by regulators in the form of gratings which are disposed one above the other, extend across the whole width of the treatment shaft and are each in the form of a single bank of bars 74, 75, Figs. 10 and 11, disposed adjacent one another, the bars of each adjacent pair in each bank being reciprocable horizontally in opposite directions, and the spacing between the bars is such that the cereal under treatment trickles through each grating when the bars thereof are being displaced, but is substantially prevented from trickling when the bars are stationary. Thus bars in a bank of compartments 43, Fig. 7, in a shaft 40 or 41, are reciprocated against the action of springs 78, 79, Fig. 10, by disc cams 76, 77 fitted on rotating or reciprocating shafts 82, 83 between two adjacent compartments. The bars have rubber mountings 80, 81 at their ends remote from those by which they are displaced and may be rotated or reciprocated about their respective longitudinal axis. They may be of solid or hollow configurations (see Fig. 9); in the latter case openings are provided for introducing or removing gas or liquid and applying suction.  Isolators in the form of slides 148, Fig. 15b (not shown) or linked rotatable flaps 159, Fig. 18, may be provided.  In order to vary the rate of trickle or the layer thickness of the cereal, the width of the shaft or compartments can be narrowed or widened utilizing reciprocable transition elements as shown in Fig. 13.  The gratings may, for example, be spaced about forty to sixty centimetres apart.  In its passage down through shaft S, Fig. 16, the grain passes through a malting section (50% of the length of the shaft), drying and final drying sections (each 25%) and a cooling section (3.5%).  The moisture content of the grain and circulation paths of air at the various stages are indicated on the drawing. The sources of air are as follows: cooling air a, hot air c from a kiln firing system, fresh air e and i, preheated fresh air g, and waste heat h from a fire box. In describing operational examples, reference is made to steeping barley in ozonised water alkaline steeping liquor or a chemical de-husking agent. <PICT:0983713/C6-C7/4> <PICT:0983713/C6-C7/5> <PICT:0983713/C6-C7/6> <PICT:0983713/C6-C7/7>
