Abstract: 1327965 Copper-containing disazo dyes BADISCHE ANILIN- & SODA-FABRIK AG 13 Jan 1971 [14 Jan 1970] 1581/71 Heading C4P The invention comprises copper-containing disazo dyes of formula wherein R and R<SP>1</SP> independently denote hydrogen, alkyl or alkoxy groups or together with the carbon atoms to which they are attached form a condensed optionally substituted benzene ring. The grouping is derived from a coupling component of the phenol, naphthol, pyrazolone or acetoacetarylamide series. The dyes may be obtained by dimerizing a copper containing monoazo dye of formula by the action of an oxidizing agent. The metallized monoazo compounds may be prepared by converting an o-hydroxy, o,o<SP>1</SP>-dihydroxy, o-alkoxy-o<SP>1</SP>hydroxy, o-halo-o<SP>1</SP> hydroxy or o-sulpho-o<SP>1</SP> hydroxy dye to the corresponding copper complex by known methods. Suitable oxidizing agents for the dimerizing process are hydrogen peroxide, alkali metal peroxides, perborates, percarbonates, organic peracids, acyl peroxides, chromic acid or atmospheric oxygen in the presence of a copper salt. The conversion of an o-hydroxy or o-sulpho-o<SP>1</SP> hydroxy azo dye into a copper containing azo dye by oxidative coppering and the dimerization of the copper-containing monoazo dye may be carried out simultaneously. The dyes give violet shades on cellulose fibres and leather.

Abstract: 1450261 Radar THOMSON-CSF 15 Jan 1974 [18 Jan 1973] 01806/74 Heading H4D If an echo pulse 1, Fig. 1 of duration Z and having a frequency band width B is applied to a cathode-ray tube display the limited resolution of the display, equivalent to a much smaller bandwidth b, will cause a spot to be displayed equivalent to an echo pulse 3. The "spreading out" of the "energy" in the echo pulse 1 can cause the spot to be too faint, any increase of the brilliance control causing further reduction of the resolution. The invention thus proposes that the pulse 1 be fed to a delay line 20, Fig. 2, having a number of tappings (including the input and output) equal to the whole number nearest to the ratio B/b, the tapping outputs being fed, via amplifiers, to a summing point via respective diodes 31-35. The pulse, together with its delayed replicas, sum to give the wider pulse of Fig. 3. This wider pulse produces a display spot of the same size as before, but much brighter. The amplifiers may be weighted such that the envelope 5, Fig. 4 of the sum pulse approximates the pulse response function of the cathode-ray tube display.
