Patent GB-1023799-A (GB)
Title: Novel azo-stilbene dyestuffs
IPC: C09B56/04
Filed: 1964-04-23
Abstract: The invention provides naphthotriazole monoazo stilbene dyes of formula <FORM:1023799/C4-C5/1> in which R1 and R2 are 1,2-naphthalene radicals A is a p-phenylene group devoid of sulphonic acid radicals, one of n and m is 2, the other is 1 or 2, and R1, R2 and A are free of chromophoric substituents.  The dyes are made by (a) coupling diazotized 4-amino-41-nitro-stilbene-2,21-disulphonic acid with an amino-naphthalene mono- or di-sulphonic acid, followed by oxidation to the triazole compound and reduction of the nitro group to an amino group which is then diazotized and coupled to an aniline compound in p-position followed by diazotization of the amino group and coupling to a naphthalene amino-, mono- or di-sulphonic acid with final oxidation to the triazole compound, or (b) coupling to the aniline compound followed by diazotization and coupling to the amino-naphthalene mono- or di-sulphonic acid and oxidation to the triazole, reduction of the nitro group to an amino group which is then diazotized and coupled to an amino naphthalene mono- or di-sulphonic acid, followed by oxidation to the final triazole compound. Preferably the radical A has the general formula <FORM:1023799/C4-C5/2> in which X1 is a lower alkyl group, X2 is hydrogen or a lower alkyl or lower alkoxy group, in which "lower" comprises a group having up to six carbon atoms.  The dyes are used for yellow shades on cellulosic materials and do not stain polyamide fibres and thus may be used to dye cellulosic/polyamide mixtures in which another dye may be used for the polyamide.

The actuator 11 for the blade switch 10 is mounted on the hold down switch bar 9, the vertical distance from the lower face of the blade holder to the switch 10 being smaller preferably by 2-10 cms. than the distance from the lower face of the hold down to the actuator 11. In operation, at the end of a cutting stroke by the blade 6, the hold down 7 has compressed the next length of the ribbon 1 as shown in Fig. 1. Downward movement of the blade 6 is reversed in conventional manner; its upward movement ends when limit switch 10 is actuated by actuator 11 on the hold down switch bar 9. Simultaneously the hold down starts its up stroke and when it reaches its uppermost position actuator 13 on the shear frame actuates switch 12 on the hold down to cause a feeder 4 to advance the length of compressed ribbon 1 below the blade 6. The next down stroke of the hold down 7 compresses the following length of the ribbon until a predetermined pressure is reached when a pressure sensitive switch starts the blade holder on its down stroke. The switch 10 or the actuator 11 can be adjustably mounted.

[Also in Groups XXXV and XL (c)] A circuit for feeding to a motor a pulse waveform having an average value which is related to an input signal, comprises a valve or semiconduotor direct-current amplifier having more than critical positive feedback and negative feedback operating with a delay greater than that of the positive feedback path so that the output alternates between minimum and maximum values the proportion of the period occupied by one of the values being related to an input signal applied to the amplifier. Fig. 6 shows an amplifier V having positive feedback through circuit RC and negative feedback through a delay circuit R2, R1, C2, C1. It is explained that the feedback causes the circuit to alternate between maximum and minimum output values and that the proportion of the period occupied by one of these values is proportional to an input signal Ue and, by suitable choice of the negative feedback circuit, may contain components proportional to the differential and if desired the integral of the input signal. Capacitor Cl could be placed before resistor R2 (Fig. 12, not shown) or could be omitted (Fig. 9, not shown). The output of the circuit is applied to a push-pull transistor amplifier feeding the field winding of a motor, one half of such a circuit being illustrated in Fig. 8 (not shown). A suitable amplifier for the two state circuit V comprises two push-pull D.C.-coupled transistor amplifier stages arranged in common emitter configuration (Fig. 13, not shown).
