Title: Manufacture of arylazo-diarylamines
IPC: C09B43/11
Filed: 1927-08-22
Abstract: 276,372. I. G. Farbenindustrie Akt.- Ges. Aug. 21, 1926, [Convention date]. Samples furnished. Azo dyes.-Arylazodiarylamines are obtained by causing a monoaminoazo dye to react with an aromatic nitro compound of the benzene series containing at least one exchangeable halogen atom and at least one sulpho or carboxyl group. The aminoazo dyes used as parent materials may be of the benzene or naphthalene series, or may contain both a benzene and a naphthalene nucleus in either of which the amino group may be present; other substituents capable of increasing the solubility, e.g. sulpho or carboxyl groups may also be present. The halogenated and sulphonated or carboxylated nitro compounds used may contain more than one nitro, sulpho, or carboxyl group; both sulpho and carboxyl groups may be present if desired. The products are soluble in water and dye animal fibres; those containing not more than one sulpho group are also suitable for dyeing cellulose esters or ethers. The condensation is preferably effected by boiling in the presence of an acid-binding agent, e.g. sodium acetate or chalk; in cases where the halogen is exchanged with difficulty, e.g. with the mononitrohalogen benzene sulphonic or carboxylic acids, the reaction may be conducted under pressure, preferably a pressure of 6-12 atmospheres. In examples, (1) p-aminoazobenzene is condensed with potassium 1-chlor-2 : 6-dinitrobenzene-4-sulphonate; the product dyes acetyl cellulose yellow; (2) aminoazobenzene is condensed with 1- chlor-2-nitrobenzene-4-sulphonic acid under pressure ; the product dyes animal fibres and acetate silk yellow. Similar products are obtained from the nitrohalogenbenzene carboxylic acids; that from aminoazobenzene and 1-chlor-2: 4-dinitrobenzene-6-carboxylic acid dyes wool reddish-yellow and acetate silk an intense golden-yellow. The Specification as open to inspection under Sect. 91 (3) (a) states that nitro compounds of the naphthalene series may be used, and comprises also an example in which p-aminoazobenzene sulphonic acid is condensed with potassium 1-chlor-2 : 6-dinitrobenzene-4-sulphonate; the product dyes wool intense yellow shades. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,061,212. Transistor amplifying circuits. DANA LABORATORIES Inc. June 2, 1964, No. 22867/64. Heading H3T. In a direct-coupled amplifier for low-level signals, means are provided for preventing errors due to pick-up of unwanted components at the input. Signals are applied in push-pull to the bases of transistors 31, 32, by means of input terminals 12, 13; these transistors comprise an emitter-coupled pair, their emitters being connected together via a balancing potentiometer 33, the slider of which is returned to a constant current source 35. Amplified signal is applied from collector circuit resistors 36, 38 to a push pull amplifier 16, from one side of which an unbalanced output is taken off over lead 18. The collector circuits of transistors 31, 32 also include a common resistor 48 across which an amplified voltage is developed proportional to any unbalanced component in the input. This is applied, together with a zero-setting potential from source 56, to an auxiliary amplifier 57. Negative feedback of both wanted signal and unwanted terms is applied to the emitters of transistors 31, 32 via a resistance network 44, 45, 46, 54, 55, 61, 63. Resistors 45, 46, also 54, 55 and 62, 63 are respectively equal so that the balanced signal from amplifier 16 is fed back in push-pull, resistor 46 being adjustable and serving to vary the amount of feedback. The collector circuit of transistors 31, 32 is returned to the common point of resistors 54, 55 and the output of auxiliary amplifier 57 is connected between ground and the common point of resistors 62, 63 so that the unwanted unbalanced component is fed back in parallel to the emitters of transistors 31, 32.
