Title: Improvements in stripping dyed textiles
IPC: D06P5/13
Filed: 1934-02-02
Abstract: Textiles dyed with azoic colours are stripped by a modification of the process described in the parent Specification which comprises including in the stripping bath a small proportion, e.g. 0,05 per cent by weight of anthraquinone, a substituted anthraquinone carrying as substituents hydroxyl, halogen, amino or alkyl groups, or a combination of such groups.  It is stated that the process can be carried out at a lower temperature, and that it is particularly suitable for stripping azoic colours from natural silk.  In examples: (1) Cotton yarn dyed with 4-chloro-2-aminotoluene --> (on the fibre) diacetoacetictoluidide is treated for 30 minutes at 85--90 DEG  C. in 40 times its weight of an aqueous solution containing caustic soda, sodium hydrosulphite, and trimethylcetylammonium bromide having dispersed in it powdered anthraquinone.  (2) Cotton yarn dyed with 5-chloro-2-aminotoluene --> (on the fibre) Brenthol AS is similarly stripped, whereas if the anthraquinone is omitted, a pale red shade remains.  (3) Cotton yarn dyed with 5-nitro-o-anisidine --> (on the fibre) Brenthol BT is similarly stripped.  (4) Yarn dyed with 5-nitro-o-anisidine --> (on the fibre) Brenthol AT is similarly stripped.  (5) Cotton yarn dyed with dianisidine \sy (on the fibre) Brenthol BA is similarly stripped.  (6) Pure silk yarn dyed with fast Red KB base --> (on the fibre) Brenthol BA is similarly stripped. The yarn may be given an after treatment with hydrogen peroxide. Specifications 294,582, [Class 2 (iii)], 392,763, and 379,396 are referred to.

Abstract: 681,477. Electric indicating systems. ZELLWEGER AKT.-GES. APPARATE-UND MASCHINENFABRIKEN USTER. Feb. 13, 1950 [March 15, 1949], No. 3637/50. Class 40 (i) [Also in Groups IX and XXXVI] In apparatus for determining the mean deviation from average of an electrical signal representing a physical magnitude e.g. the quantity of substance in the cross-section of textile slivers, yarns or rovings, the fluctuating signal component representing the deviations from the average value and the steady component representing the average value are separated by a low-pass filter and the former component is rectified, averaged in a second low-pass filter, and measured by an electrical recording instrument. In Fig. 3 an electrical instrument 30 of the kind described in Specification 638,365, [Group XXXVI], for measuring the quantity of substance in textile slivers supplies a fluctuating signal for a capacitance-resistance (or inductance) low-pass filter 31 whose output, representing the steady average value, is measured by a recording instrument 32, 33. The alternating signal across the ends of filter resistances 40, 42, 44, representing the deviations from the average value, energizes a bridge rectifier 34 through a condenser 39, and the unidirectional output is applied to a second resistance-capacitance low-pass filter 35 to produce a steady output, representing the mean deviation from the average value, which is measured by a recording instrument 36, 37. The rectifier or measuring instrument characteristics may be such that the R.M.S. value of the deviation is recorded.

Title: Fused salt electrolytic method and apparatus
IPC: C25C7/06
Filed: 1960-02-05
Abstract: A fused salt bath is electrolyzed by applying thereto, before or during electrolysis by a continuous low voltage direct current, a series of unidirectional high tension pulses at a voltage high enough to produce a lasting increase in the conductivity of the melt but not so high as to cause dielectric breakdown of the melt.  The pulses may be applied through the same electrodes as the electrolyzing current or through separate electrodes and may have a voltage of 1200 to 3000, and a duration, at peak voltage, of 1 to 10 micro seconds.  A sequence of from four to ten pulses within a period of from one to ten seconds, repeated every hour, produces a significant increase in the conductivity of the bath.  Medium tension pulses of about 1000 volts may be employed, at intervals of one-half second, in addition to the high tension pulses.
