Filed: 1961-11-29
Abstract: The invention comprises vat dyes containing at least 5 or at the most 6 condensed rings fused together, at least one stable sulphonic acid group and at least one carboxylic acid amide group. The term "vat dyes" is defined as including dyes that can be converted by reduction into a leuco form, which has better affinity for natural or regenerated cellulose fibres than the unreduced dye and which can be reconverted into the original chromophore system by oxidation.  The dyes may be prepared by reacting a suitable vat dye, i.e. one containing at least 5 or at the most 6 condensed rings fused together and (a) at least one carboxylic acid amide group with a sulphonating agent so as to introduce at least one SO3H group or (b) at least one carboxylic acid amide group and at least one sulphonic acid halide group with a mild hydrolysing agent, or (c) at least one acylatable amino group with an acylating agent which, if the dye does not contain a sulphonic acid group, contains a sulphonic acid group or a derivative thereof which is converted into a sulphonic acid group under the reaction conditions, or (d) at least one carboxylic acid amide group and at least one mercapto group with an oxidizing agent. In examples, the preparation of vat dyes containing di-(acylamino-anthraquinonylamino) - anthanthrone, anthraquinone - benzacridone and dibenzpyrene-quinone residues is specified. Specified acylating agents include diphenyl - 4 - carboxylic acid chloride, thiophene - 2 - carboxylic acid 4 - sulphochloride, terephthaloyl and isophthaloyl chlorides, oxalyl chloride, succinyl chloride, naphthalene-2,6-dicarboxylic acid chloride, 4,41-diphenyl- or -diphenylsulphone- or -diphenylmethane- or -diphenylamine - dicarboxylic acid chloride, azobenzene - 2,21 - dicarboxylic acid chloride, pyridine-2,6-dicarboxylic acid chloride, benzoic acid-m-sulphochloride and 2-mercaptobenzthiazole-6-carboxylic acid chloride.

Title: Binary data handling system
Inventor: KING CHIA-CHENG
IPC: G11B20/14
Filed: 1968-09-17
Abstract: 1,235,547. Data storage. BURROUGHS CORP. 17 Sept., 1968 [18 Sept., 1967], No. 44063/68. Heading G4C. A binary data handling system includes a storage medium from which phase-encoded binary data is read to produce data pulses at regular intervals and phase pulses between at least some of them, the data pulses being gated to utilization means under control of a monostable switched to its quasi-stable state by each data pulse and switching back to its stable state after a time interval controlled by a directcurrent control voltage representative of the ratio of the duration of the quasi-stable state to the duration of the period of the multivibrator. Positive-going and negative-going transitions in phase-encoded binary data on magnetic tape (or drum) 1 produce pulses on lines B, B<SP>1</SP> respectively. Each pulse triggers a monostable multivibrator 10 via an OR 9 to produce a blanking pulse which prevents non-data pulses from passing through ANDs 23, 24 to a utilization circuit 19. (Each data pulse occurs at a cell centre whereas each non-data pulse occurs at a cell boundary). A control voltage generator 21 has a first capacitor which is charged at a constant rate during the blanking pulses and discharged at a constant rate in their absence. A second larger capacitor follows the voltage across the first and averages it to provide a control voltage which controls the duration of the blanking pulses produced by monostable 10, so that it is a fixed fraction of the monostable period, thus compensating for tape speed variations. Each block of data starts with a preamble of all zeros to preset the control voltage. The data pulses from this preamble all occur on line B<SP>1</SP> and the non-data pulses on line B. The latter are not used in the presetting since a flip-flop 26 is reset to disable an AND 27. Counter 25 counts the preample bits and sets flip-flop 26 at a predetermined count sufficient for presetting of the control voltage to have been accomplished. Flip-flop 26 and counter 25 are reset by a block-end mark on tape/drum 1. Two channels B, B<SP>1</SP> are used above, but unipolar or bipolar pulses on a single channel could be substituted. The signals supplied to the utilization circuit 19 could be used to recover the phase-encoded binary data.
