Title: Water-Insoluble Anthraquinone Dyestuffs and processes for their manufactur and use
IPC: C09B1/503
Filed: 1967-09-18
Abstract: 1,158,065. Heterocyclic anthraquinone dyes. CIBA Ltd. 18 Sept., 1967 [22 Sept., 1966], No. 42335/67. Heading C4P. The invention comprises 1,5-dihydroxy-4,8- dinitro- or 1,5-dihydroxy-4,8-diamino anthraquinones which contain an aromatic carbocylic ring fused to a 5- or 6-membered ring containing one or two hetero atoms bound through the aromatic carbocyclic ring to 3- and/or 7- position of the anthraquinone nucleus. Preferred dyes have the general formula wherein W is O or S, R 1  and R 2  which may be the same or different are hydrogen or alkyl optionally substituted by hydroxy, acyloxy or alkoxy, R 3  and R 4 , which may be the same or different, are alkyl, e.g. C 1 -C 4  alkyl, Y is a saturated or unsaturated alkylene group optionally substituted by at least one alkyl group; and X 1  and X 2 , which may be the same or different, are hydrogen or halogen, or wherein R 1 , R 2 , X 1  and X 2  are as above and R 3 , R 4  and R 5  are alkyl groups, preferably C 1 -C 4  alkyl groups. They are prepared by reacting a boric acid ester of 1,5-dihydroxy- 4,8-dinitroanthraquinone with a compound containing an aromatic carbocyclic ring fused to a 5 or 6-membered heterocyclic ring containing one or two hetero atoms, hydrolysing the boric acid ester group in the product and optionally reducing the nitro groups to amino groups. Preferably condensation takes place at - 20‹ to + 20‹ C. in presence of sulphuric acid. Preferred anthraquinone starting materials are not further substituted or contain halogen in the 6- and/or 7-positions and the heterocyclic compounds used include chromans, chromenes, benzofurans, benzodioxanes or their sulphur analogues. Reduction of the nitro groups may be prior or subsequent to the hydrolysis stop. The product may also be halogenated or alkylated. The dyes dye polyesters, e.g. polyethylene terephthalate in blue and greenish blue shades and reserve cotton.

Abstract: 1,204,365. Automatic phase control. STANDARD TELEPHONES & CABLES Ltd. 21 Sept., 1967, No. 42931/67. Heading H3A. An oscillator 1, 2, 3, 4, of the type in which a sinusoidal output is synthesized by generating a pulse train having a suitably arranged pulse distribution and frequency, is synchronized with an incoming signal 7 by multiplying the two signals together in a modulator 5, 6, 8, and feeding the resultant to an integrator 9, the output of which provides a control signal for the oscillator. The integrator output is fed to two reference circuits 10, 11 so that an error signal is produced whenever the phase difference exceeds the permitted limits. This error signal is then fed via gating circuits 13, 14, 15, 18 to add or inhibit a pulse to the clock pulse train 16 from which the sinusoidal signal is synthesized. The sinusoidal signal is derived from the 7th to 11th stages of a 12-stage divider 1, the initial 6 stages being employed to give a fine phase adjustment. Coarse phase adjustment may be provided by inserting or inhibiting pulse at, say, the 7th stage.
