Patent GB-192842-A (GB)
Title: Manufacture of new dyestuffs
IPC: C09B57/00
Filed: 1921-11-28
Abstract: Vat or pigment dyes are obtained by condensing a p-diazine in which the p-position to an azine nitrogen atom is substituted by a group containing hydrogen capable of being replaced by metal, such as eurhodols or naphthsultamphenazines, with a 1 : 4-quinone or naphthsultamquinone containing halogen in the 2-position.  The reaction is preferably effected in the presence of an agent which combines with hydrochloric acid, such as sodium acetate, and an oxidizing-agent, for instance by blowing in air or adding ferric chloride; when 2 : 8-dihalogen-1 : 4-quinones are employed an oxidizing-agent is not required; when halogenated eurhodols are employed a metal such as copper is added.  According to examples:-a product giving yellow shades on cotton is obtained by condensing the eurhodol from 2-oxy-1 : 4-naphthoquinone and 1 : 2 - diaminobenzene with 2 - chlor - 1 :-4 - naphthoquinone or 2 : 3 - dichlor - 1 : 4 - naphthoquinone; the oxytoluphenazine from 2-oxy-5-methyl-1 : 4-benzoquinone and 1 : 2-diaminobenzene is condensed with 2 : 3-dichlor-1 : 4-naphthoquinone, giving a yellow cotton dye; two molecules of the eurhodol referred to above are condensed with one molecule of chloranil, giving a dye which dyes cotton dark green, becoming brownish-yellow by the action of air or other oxidizing-agent; a yellow dye is prepared by condensing the eurhodol from 2 : 3-dichlor-1 : 4-naphthoquinone and 1 : 2-diaminobenzene with 2 : 3-dichlor-1 : 4-naphthoquinone; an orange dye is obtained from the eurhodol from 2 : 3-dichlor-1 : 4-naphthoquinone and 1 : 2-diaminonaphthalene and 2 : 3-dichlor - 1 : 4 - naphthoquinone; naphthsultam-3 : 4-phenazine is condensed with 2 : 3 - dichlor - 1 : 4 - naphthoquinone giving a greenish-yellow dye; the eurhodol first-mentioned above is condensed with 2-chlor- or 2 : 3-dichlor-4-naphthsultamquinone, giving a product which dies cotton yellow-brown shades turning to orange by treatment with bleaching-powder; equimolecular parts of naphthsultam-3 : 4-phenazine and chloranil are condensed to give a yellow cotton dye; this on further condensation with another molecule of naphthsultam-3 : 4-phenazine gives a product dyeing cotton brownish-yellow shades turning to orange by treatment with bleaching-powder.

Abstract: 1,264,805. Image analysis. IMAGE ANALYSING COMPUTERS Ltd. 29 April, 1969 [1 May, 1968], No. 32024/71. Divided out of 1,264,804. Headings G4A and G4D. Parameters of features on a screen are computed from data obtained by successive line scanning of the screen. Whenever the scan is passing over a feature an intersect pulse is applied to 10. Each scan is compared with the preceding scan by loop 12, 14, 16 so that a pulse V<SP>1</SP> is applied to differentiator 32, V<SP>1</SP> starting when an intersect pulse starts and stopping at the end of an intersect pulse or at the end of a coincident pulse, whichever is the later. The bottom right hand corner of a feature is detected by an anti-coincidence circuit 18- 26. A selected parameter of each intersect pulse is registered in module C. Module B holds the computed value up to the previous scan, and A computes the new value. The end of a feature indicated at 22 clears the modules A, B, C. The parameters can be height, width, area or perimeter. Addition.-The A, B, C modules and associated delay system 28 may use a register, Fig. 2, with a series of adders S1-S3, having inputs a, b with outputs s, c representing sum and carry. Delays increase with the value of the stages. The delay lines may be replaced by shift registers.

Filed: 1973-07-05
Abstract: 1412560 Colour television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 July 1973 [7 July 1972 (2)] 32050/73 Heading H4F A PAL colour television signal to be recorded is separated into its chrominance and luminance components, an index signal, Fig. 11(g) being derived from the colour bursts and added, during alternate line blanking periods, to either the chrominance signal, Fig. 11(h), or the luminance signal, the index signal being separated during play back and used to operate a switching circuit 129, Fig. 10, to change, during alternate line periods, by 90 degrees the phase of the output of either a burst gate 126 or a variable frequency oscillator 131 fed to a phase comparator 130, the output of oscillator 131 being used to remove jitter in the reproduced chrominance signal. In the embodiment of Fig. 10, the luminance signal is frequency modulated 104 and passed to a mixer 106 which also receives the chrominance signal, Fig. 11 (h), which has been converted to a low frequency and has had the index signal, Fig. 11(g), added to it. The index signal is derived by adding the output of burst gate 107 after it has passed through a 90 degree phase retarder 108, Fig. 11(b), with the same output delayed by a one line delay line 109, Fig. 11(c), to derive the signal of Fig. 11(d), which is passed through circuits 110, 111, 112 to derive the index signal, Fig. 11(g). The index signal is separated from the reproduced signal by separator 127 and controls a multivibrator 128 and hence switch 129, the index signal being removed from the chrominance signal in a gate 135. The index signal may alternatively be added to the luminance signal prior to frequency modulation thereof (Fig. 12, not shown), the index signal being derived from the half-line frequency output of a phase comparator (215) receiving the outputs from an oscillator and burst gate. Either the index signal or the luminance or chrominance signal is then delayed by one line period before the signals are combined.
