Title: Video signal reproducing system for colour television receiver
IPC: H04N9/26
Filed: 1964-01-27
Abstract: 1,058,282. Television. YAOU ELECTRIC CO. Ltd. Jan. 27, 1964 [Jan. 25, 1963 (3)], No 3395/64. Heading H4F. In a colour television receiver for an NTSC transmission system and utilizing a single gun type of picture reproducing tube provided with a colour switching grid electrode operated at line scanning frequency to effect line sequential colour reproduction the colour signals (specifically signals approximating closely to the colour-difference signals R-Y, G-Y and B-Y) controlling the intensity of the tube beam are derived by detecting the received chrominance sub-carrier at 120 degrees phase positions by means of a de-modulating wave the frequency of which differs from that of the sub-carrier by three times the line frequency and the phase of which is synchronized with that of the sub-carrier during every third line scan and is further adjusted during each line scan. The de-modulating wave is produced by a crystal oscillator 16 (Fig. 1) the phase of which is adjusted by a variable reactance 15 in accordance with the output of a phase detector 14 supplied with the output of 16 and, during every third line scan period, with the synchronizing colour-burst from an amplifier 13 fed from the video amplifier 4 and gated to pass the colour-burst by means of pulses of 1/3 line frequency produced in generator 20 controlled by the horizontal scanning circuit 11. Because of the relationship between the frequency of the de-modulating wave from oscillator 16 and that of the chrominance subcarrier a progressive change of one cycle (i.e. 360 degrees phase) occurs between these two frequencies during the period of three line scans so that the 120-degree phase change which occurs during each line period allows the demodulating wave to be employed to detect signals approximating closely to the colourdifference signals R-Y, G-Y and B-Y. However, since the 120 degrees phase change occurs progressively throughout each line scan period the direct use of the output of oscillator 16 as the de-modulating wave would result in a colour change during each line scan and to prevent this the phase of the output of 16 is controlled in a phse modulator 17 by a sawtooth wave of line frequency derived from a shaping circuit 19 controlled by the horizontal scanning circuit 11. This causes the phase change to occur in discrete steps and the demodulating wave so controlled is utilized in the chrominance detector 18 to demodulate the chrominance sub-carrier supplied thereto from a band-pass amplifier 12. The colour-difference signals thus derived in line sequence are supplied to the control-grid of the picture to the cathode of which the luminance signal Y is fed and to the colour switching grid of which a stepped rectangular wave- (Fig. 3, not shown) generated via a ring counter 21 is fed to direct the scanning beam during each line scan period to the colour phosphor strip appropriate to the colour to be reproduced.

Abstract: 694,289. Making superheater and like return bends. HUET, A. Feb. 12, 1952, No. 3682/52. Classes 83 (ii) and 83 (iv). A method of bringing together the branches of a breeches connection or of a U-tube bend or manifold having an aperture or tube opening, comprises inserting a forked punch or die into the end aperture so as to stiaddle the inner region of the bend, heating said inner region and applying pressure to the punch to bring together the inner walls of the branches of the bend or connection. A punch d is introduced through an aperture b in a U-shaped bend a, said punch having forked limbs e<SP>1</SP> and e<SP>2</SP> which are placed over the crotch c of the bend. The branches of the bend are gripped between dies g<SP>1</SP> and g<SP>2</SP> and after heating the crotch c the punch d is forced downwardly to bring the branches f together. The aperture b may also be brought to the desired shape by utilizing the diameter of the punch d and providing a sleeve g which acts as a stop for the aperture edge, and the dies g<SP>1</SP> and g<SP>2</SP> are shaped to give the bend or connection the desired external shape.

Abstract: 889,159. Dielectric heating ovens. RADYNE Ltd. Nov. 30, 1960 [Feb. 3, 1960], No. 3885/60. Class 39(3) Dielectric heating apparatus comprises at least two ovens, through which passes a conveyer band for carrying the material to be heated, and control means serving to initiate or increase the heating in a subsequent oven and to prevent or restrict further increase in the power drawn by a given oven when this power reaches a predetermined value. In the arrangement shown moist biscuits of varying thicknesses are carried by a conveyer band 2 through a conventional baking oven 4, employing for example hot air or radiation heating, and through three dielectric heating ovens 6, 8 and 10, each having a work electrode 12 and a generator 14. Ovens 6 and 8 are provided with control devices 16 and 18 respectively, each including a motor controlled by the cathode current of the oscillator valve of the associated generator 14. The generator 14 of the first oven 6 may be brought into operation by a device which measures the moisture content or the thickness of the biscuits. If the biscuits become wetter or thicker more power is drawn from the first generator 14 and the control device 16 raises the work electrode 12 of the oven 6 when the power reaches a given limit. In rising, the electrode 12 operates a switch to energize the generator 14 of the second, oven 8. The generator 14 of the third oven 10 is brought into operation in the same way by control device 18. The control devices 16 and 18 operate in a similar manner to lower the electrode 12 of ovens 6 and 8 and to switch off the generators 14 of ovens 8 and 10 on a decrease in thickness or moisture content of the biscuits.
