Title: Improvements relating to modulators
Inventor: LOMER GEOFFREY JOHN
IPC: H04N9/65
Filed: 1963-09-25
Abstract: 1,099,013. Amplitude modulator. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 17, 1964 [Sept. 25, 1963], No. 37645/63. Heading H3R. In an amplitude modulator particularly for a colour television system in which both a video signal and a sub-carrier signal, whose phase determines the picture line, modulate the carrier signal means are provided for reducing the sub - carrier differential phase error which occurs when the sub-carrier modulates the carrier signal due to the variation in input impedance of the modulator produced by the variation in level of the video signal. Modulator valves 3, 40 and modulated amplifier valves 12, 44 form a pair of cathodedriven modulators having a common output circuit 18. Carrier signal is applied to the modulators in anti-phase via terminal 6 and coupling coils 7, 42 and the modulating signal is applied in anti-phase via terminals 35, 36 to the grids of valves 3, 40. The cathode currents of the modulators are adjusted so that cross-over occurs at the peak white level of the video signal and the phase error occurring at this level of video signal is obtained at the black level of the video signal by adjustment of the value of the modulating voltage applied to valve 40 relative to that applied to valve 3 by varying potentiometer 39. By this means the differential phase error over the amplitude range of video signal is maintained substantially constant.

Abstract: The invention comprises 5,6-benzomorpholone derivatives of the formula <FORM:0815279/IV (b)/1> where X is an unsubstituted or substituted alkyl group or an aryl group, particularly a 2-oxo-alkyl or a carbalkoxyalkyl group.  The compounds may be prepared by hydrogenating the product obtained by condensing o-aminophenol with an alkyl a -ketocarboxylic acid ester of formula X-CO-COOY, where Y is an alkyl radical containing 1-4 carbon atoms.  Suitable esters are the methyl, ethyl, propyl and butyl esters of pyroracemic, phenylglyoxylic, acetyl pyroracemic, oxalacetic and oxalosuccinic acids.  The condensation may be effected in a solvent, e.g. alcohols or hydrocarbons; heating may be necessary, e.g. to 80-170 DEG  C.

Title: System for coding two-dimensional information
IPC: H04N1/417
Filed: 1974-08-30
Abstract: 1481226 Data transmission; facsimile systems KOKUSAI DENSHIN DENWA KK 30 Aug 1974 [31 Aug 1973 22 May 1974] 37939/74 Heading H4P A system for coding two dimensional information of lines and U columns forming a block comprises detecting when each column has no information change relative to the previous column and coding the number of columns of a basic block and number of subsequent similar columns or if there is information change within a block in one column relative to a preceding column, information in the block is coded. In one example exclusive OR circuits 11-14 each receive information from successive scanned lines, each bit being compared with the immediately preceding bit stored in a flip flop circuit, e.g. FF1 giving 0/1 on correspondence or otherwise. Exclusive OR circuits 12a-14a obtain columnwise correlation. Outputs are fed into registers 21-24, flag circuits LF1-LF4, and OR circuit 5 the output of which is applied to a column indicator CF, scale of six counter 2 and column number counter 3. LF1-LF4 each indicate information change in a line of six bits. Register CF is shifted for each 1 output from OR5; LF and CF are both reset to 0 by output from counter 2 which also sets counter 3 to counting clock pulses of generator 1 and which is stopped by a 1 from OK5. If the value at this time is more than 6, which implies continuation of more than six columns with the same information, counter 3 transfers its content to register 7 and sets F to 1 and resets itself to 0. If counted value is less than 6 counter 3 resets itself to 0. However if counter 2 is counting when OR5 issues a 1 it continues counting and does not stop until counter 3 reaches 6. A decision circuit 18 monitors output from F and counter 2 and when F sets to 1, 0 is applied from decision circuit 18 to combiner 9 when an enabling output from counter 2 applied to 18 causes a 1 to be applied to 9. Circuit 18 decides line and column information to be transmitted in dependence on information supplied from LF and CF. When a 1 is applied to 9, the contents of LF and CF in the form of line and column designating bits decided by 18 is transferred through 9 to memory 10, content of which is transferred through a transmitting circuit 100. When 18 supplies a 0 to 9 it is transferred to memory 10 together with the content of register 7 at which time it is reset to 0. The corresponding receiver (Fig. 11, not shown) is substantially the reverse process of coding as described with reference to Fig. 10. Other arrangements are described in the Specification. It is stated that the arrangements disclosed may be used with other types of digital information, e.g. analogue information such as a television signal sampled and coded as in p.c.m. where reference levels are regarded as information changing points.
