Title: Improvements in dyeing nitrogenous fibres
IPC: D06P1/607
Filed: 1960-07-14
Abstract: In the dyeing or printing of nitrogenous fibres by the process of the parent Specification, wherein the fibres are treated with an aqueous bath or paste containing a 1 : 2-chromium or -cobalt complex compound of an azo dyestuff, the complex containing at least two acid solubilising groups, together with a compound containing at least one basic nitrogen atom to which is bound a residue containing a polyglycol ether chain, improved results are obtained by also incorporating in the bath or paste an organic, non-ionisable, hydrophilic compound that is at most restrictedly soluble in water such as benzyl alcohol, b -phenoxyethyl alcohol, geraniol, cyclohexanol, n-butanol, amyl alcohol, n-hexanol, 2-ethyl-hexanol and n-octanol.  Dyeing is effected from an acid bath at a temperature not exceeding 80 DEG C.  The fastness of the dyeings is improved by adding an alkaline substance, such as ammonia, hexamethylene tetramine, sodium bicarbonate or triethanolamine, to the bath after the fibres have absorbed the desired amount of dyestuff.  One example describes slubbing printing on woollen tops, the paste containing besides the dyestuff and tragacanth thickening, the reaction product of ethylene oxide and oleylamine, together with benzyl alcohol, urea and acetic acid.

Abstract: 1299055 Automatic gain control STORAGE TECHNOLOGY CORP 19 April 1971 [23 March 1970] 25649/71 Heading G4H [Also in Division H4] . A magnetic tape system comprises a plurality of magnetic tape units each adapted to read signals from a plurality of tracks, the signals from the units being applied to at least one read bus common to the units via an automatic gain control device individual to that unit and including a digital counter which stores gain control signals. The Figure shows part of the amplifier and gain control circuitry of a single unit. Signals from a single track or channel are picked up by a read head 20, amplified at 21 filtered at 22, amplified at 23 and applied to the read bus. The output of the filter is also amplified and rectified at 24 and fed to a peak holding circuit 25 and 26. The resulting smoothed envelope signal is combined with similar signals from other channels of that unit at an amplifier 27 to provide a sum or average envelope signal. The resultant analog envelope signal is compared with three reference levels set by comparators 28, 29 and 30 the outputs of which are applied to gates 32 and 33. At the end of each signal block the receiving apparatus (e.g. a computer) applies a signal at a terminal 38 which allows gates 32 and 33 to respond setting a latch 34 or 35 at this time if the compared signal level is between the lower or between the upper two threshold levels respectively. A counter 39 initially set to a count of 4 is stepped up or down by one step if either latch 34 or 35 is set switching gain control resistors 41 to 43 into or out of the feedback path of the gain control amplifier. The counter has eight states and the resistors 41 to 43 are used in all combinations to provide eight different gain levels.

Abstract: 710,658. Pulse generating circuits. KELVIN & HUGHES, Ltd. Oct. 2, 1952 [Nov. 6, 1951], No. 25981/51. Class 40 (6). [Also in Group XXXV] In a high voltage pulse generator comprising an iron-cored transformer for supplying pulses to a modulator, a pulsed flux is applied to the iron core between successive output pulses thus reducing the magnetization of the core by the output pulses and preventing, saturation, the modulator being unaffected by the pulsed flux. The Figure shows a modulator for a radar transmitter which produces negative-going pulses at the cathode 2 of magnetron 1 and' also at the output terminal 20. The output from a low voltage A.C. supply 4 is rectified by rectifier 8 to charge the pulse forming network 9 on successive half cycles, it being discharged in the intervals via transformer winding, 12 when, spark gap 10 is triggered by pulses applied at 18. A negative-going pulse is produced at cathode 2 from the double winding 14 of transformer 13 which effectively matches magnetron 1 to the output line connected at terminal 20. During current flow in winding 14 magnetization of the iron-core of transformer 13 is produced and this is substantially neutralized by the passage of a suitably phased current pulse through winding 15. This is produced from an A.C. supply 21, which is derived from and phase-locked to A.C. supply 4, by use of rectifier 17 and saturable choke 16, so that the flux generated in the core of transformer 13 by winding 15 occurs mid-way between the application of successive pulses to the magnetron 1 and restores the core to the desired condition. Since the cathode of the magnetron is driven positively during the demagnetizing pulse it is unaffected by this pulse.
