Title: Manufacture of water-insoluble azo-dyestuffs on wool materials
IPC: D06P3/22
Filed: 1934-09-17
Abstract: Water-insoluble azo dyes are made on wool or mixtures of wool with regenerated cellulose artificial silk by grounding the material in a continuous operation for at most three minutes with a strongly alkaline solution of a coupling component containing preferably a highly active wetting agent, freeing from water by squeezing and developing without an intermediate drying operation by treatment with a diazo solution.  The material before grounding may be bleached by means of an agent yielding oxygen or feebly chlorinated.  After treating with the diazo solution the material may be passed through a weakly alkaline bath.  The dyeings may be finished by an after-treatment with reducing agents. Acidification at raised temperature is advisable in cases in which the shades of the dyestuffs vary with the size of the dyestuff particles.  Fast vivid dyeings are obtained on piece goods, slubbings and warps.  In examples: (1) dry slubbing is passed for about 30 seconds under guide rollers through a solution containing 1-(2<1> : 3<1>-hydroxynaphthoylamino) - 4 - chloro - 2 - methylbenzene, alcohol, caustic soda, sulphite cellulose waste liquor, oleic acid ester of methyltaurine and sulphonated oleic acid ethylanilide, squeezed, passed through air, then through a solution of diazotized 4-chloro-2-methyl-1-aminobenzene containing the reaction product from ethylene oxide and octodecyl alcohol and sodium acetate, again squeezed, passed through air, then through a cold bath containing ammonia and the condensation product from ethylene oxide and octodecyl alcohol, rinsed in a boiling bath containing acetic acid and the oleic acid ester of methyltaurine and rinsed; a fast vivid red is obtained; (2) non-wetted, bleached cloth used for flags is dyed as in (2).  Sulphonated oleic acid di-isobutylamide may also be used as a wetting agent in the dye-bath.  The Specification as open to inspection under Sect. 91 comprises also the following examples: (1) chlorinated muslin is grounded as above with the anilide of 2 : 3-oxynaphthoic acid, squeezed, treated with a solution containing 4<1> - methoxydiphenylamine - 4 - diazonium chloride, acetic acid and the reaction product from ethylene oxide and octodecyl alcohol, the coupling completed by passing through a bath containing ammonia and the oleic ester of methyltaurine, rinsed, acidified at boiling temperature and rinsed; the N-nitroso compound of the diazo component may be used in which case formaldehyde-sulphoxylate is added during the acidifying at boiling temperature; using the o-toluidide of 2 : 3-oxyanthracene carboxylic acid a bluish green is obtained; (2) slubbing is grounded as above with the p-chloroanilide of 2 : 3-hydroxycarbazole carboxylic acid and developed with diazotized 1-amino-2-methoxy-5-chlorobenzene.  This subject-matter does not appear in the Specification as accepted.

Filed: 1949-10-21
Abstract: 665,951. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd. Oct. 21, 1949, No. 27088/49. Class 40 (iv). In a carrier current communication system the gain of certain amplifiers is controlled in accordance with the resistance variations of a conductor included in the transmission cable and more accurate gain control is effected in a later amplifier by a pilot current transmitted with the communication signals. In Fig. 1, stations 2 and 6 are controlled by a pilot current and the intermediate stations are controlled according to the impedance of auxiliary cables 12, 13 and 14 which are stranded up in the same cable with the main signal circuit and shortcircuited at the preceding station. The gain control devices 9, 10 and 11 at the intermediate stations comprise an oscillator 18 which is an amplifier having a bridge network 19, which is slightly unbalanced so that the loss through the feed-back path is equal to the gain of the amplifier. A change in the resistance of the line 12 causes the bridge 19 to become unbalanced so that a change occurs in the amplifier output level to change the resistance of a thermistor 17 in the signal amplifier feed-back path and of a thermistor 20 to restore the bridge to its original condition. Specification 510,379, [Group XL], is referred to.

Abstract: 1,212,747. Selective punching apparatus. ZAVODY PRUMYSLOVE AUTOMATIZACE, NARODNI PODNIK. 10 June, 1968, No. 27441/68. Heading B4B. Apparatus for punching holes in a recording medium, such as punch tape, has a plurality of punches each selectively operable by its own control means, each control means including an elongate rail 5 governed by two actuating members, the first of which is a driving member, which continuously imparts to the rail a to and fro motion transverse to its length, and the second of which is a stop number, which selectively arrests this motion at one point, the stop member being selectively controlled of electromagnetic means. The drive is common to all punches. As shown in Fig. 1, the apparatus comprises a rail 5 which is continuously oscillated by means of an eccentric 101 rotatable on a driving shaft 11 and is supported at one end by leaf springs 13, 14. The apparatus also comprises a stop lever 15 rockable about a pivot 16 acted on by a spring 18. The lever 15 has arms 15a, 15c, the arm 15a having a projection 15b while the other arm 15c has a ledge 15e engaging the rail 5. In idling operation, the rail 5 swings freely and no punching occurs. If however, the electromagnet 19 is energized, the lever 15 is arrested and the projection 15b fixes the end of the rail 5 so that the rail swings and the tape 1 is punched. In another arrangement, the eccentric is replaced by an eccentric pin on a rotatable disc entering a slot in the arm, Fig. 2 (not shown) or the arm is spring-influenced against a cam, Fig. 3 (not shown). In another modification, the apparatus comprises a connecting rod 23, Fig. 4, connected to a crank on a driving shaft 11, the rod being coupled by a resilient joint 22 to an actuating lever 104 provided with cross bars 8, 9 between which the rail 5 passes and provided with elements 20, 21 engageable with one arm 15d of the stop member 15. Arm 15a of the stop member is acted on by a tension spring 18. In a still further arrangement, one end of the rail 5, Fig. 7, is provided with a slot 30 for receiving the head 15b of the stop lever 15 in the non-working state of the rail. Also in this arrangement the actuating rod 107 has cross bars 8, 9 between which the rail passes and elements 20, 21 for arm 15d of the stop lever.
