Title: Water-soluble reactive dyes
Inventor: BENZ JAKOB
IPC: C09B62/02
Filed: 1962-11-29
Abstract: The invention comprises water-soluble reactive dyes of formula <FORM:1027614/C4-C5/1> wherein D is a dye radical (e.g. a mono- or dis-azo, metallized azo, anthraquinone or phthalocyanine dye radical) which contains at least one water-solubilizing group, R is hydrogen or alkyl which may be substituted, X is a substituted heterocyclic bridge member of the 1,3-diazine or 1,3,5-triazine series, Z is a C4-C7 alkylene group and n is 1 or 2.  The dyes are prepared by reacting a suitable dye containing a replaceable halogen atom linked to the diazine or triazine ring with an equimolar amount of an N-amino-heterocyclic compound such as N-amino-penta-or-hexa-or-hepta-methylene-imine or, preferably, N-aminopyrrolidine, in such a manner that addition of the compounds takes place with simultaneous quaternation without loss of a proton. Alternatively dyestuff intermediates may be similarly reacted and converted by condensation reactions (e.g. azo coupling) into the dyes.  The dyes may be used to colour natural and synthetic polyamides and particularly cellulose materials by the usual reactive dye processes.ALSO:Triazine or pyrimidine derivatives containing a residue of formula <FORM:1027614/C2/1> wherein X is triazine or pyrimidine ring and Z is a saturated aliphatic chain having 4 to 7 carbon atoms are described.  They are used as dyestuff intermediates (see Division C4). In Examples: (4) 1-amino-3-[21,51,61-trichloropyrimidyl -(41) - amino] - benzene - 6 - sulphonic acid is condensed with N-aminopyrrolidine; (7) 1 - [61 - chloro - 41 - (411 -sulphophenyl-amino) - 11, 31, 51 - triazinyl - (21) - amino] - 8-naphthol-3,6-disulphonic acid is condensed with N-aminopiperidine; (12) 1-[21, 51, 61-trichloropyrimidyl - (41) - amino] - 8 -naphthol - 3,6-disulphonic acid is condensed with N-amino-pyrrolidine.

Divided out of 454,653. [Class 106 (i)] Counting - mechanism particularly for use in totalizators operated in a stepwise manner by impulses received from a primary mechanism is provided with a transfer mechanism between each denomination including a cam which actuates a spring-pressed lever carrying an arm with a pin engageable with a toothed wheel of the next higher denomination and under the control of a reciprocating link driven synchronously with the cam. In the form shown an electromagnet 1, Fig. 1, receives impulses and actuates a spring controlled armature 2 that carries a pawl 4 to impart a unidirectional rotation to a ratchet wheel 5. The wheel 5 transmits rotation to a spur wheel 9 in the manner described in Specification 454,653. The wheel 9 meshes with a pinion 12 geared to the units indicating disc 17. As shown in Fig. 2, two pinions 12, 12a are provided and receive movement from the spur wheels 9 of two impulse driving mechanisms. The pinions 12, 12a are connected through a differential gear 13 and wheels 14, 15 to the units spindle 16. Transfer mechanism.-A carry over to the next higher denomination disc 110 is effected by a snail cam 18, Fig. 3, on the spindle 16 co-operating with a roller 107 on a spring controlled lever 19 to which is pivoted a link 109 presenting a pin 21 to a toothed wheel 22 on the spindle 16a of the next higher denomination. The movement of the pin 21 into and out of engagement with the teeth of the wheel 22 is controlled by the arcuate slot 23 in one end of a slide 24 the other end of which is connected to a crank arm 25 operatively connected by an arm 111 and link 26 to an eccentric pin 27 on the cam 18. Overthrow of the wheel 22 is prevented by pins 30 on the slide co-operating with the teeth of the wheel. The pin 27 carries a roller 28 adapted to co-operate with a set of contacts 29 to control a distant indicator. Zeroizing mechanism.-To reset the indicating discs a weighted master lever 82, Fig. 2, is raised to withdraw clutch elements 112 from driving relation with the mating elements 113 to disconnect the driving means and to subject the spindles 16, 16a, &c., to the action of the spring controlled levers 19 through the cams 18 thereby causing the spindle to rotate to their initial or zero position with the rollers 17 in the cam depressions 18a. The lever 82, at the same time, displaces the contacts 29 so as to be clear of the roller 28.

Abstract: 1277065 Ultrasonic inspection devices INSTITUT MEKHANIKI POLIMEROV AKADEMII NAUK LATVIISKOI SSR 22 Sept 1969 [20 Sept 1968 (2)] 46464/69 Heading H4D In a system for measuring the ultrasonic wave propagation characteristics in a specimen by comparing the waves received at one receiving transducer from two transmitting transducers or at two receiving transducers from one transmitting transducer after travelling two paths in the specimen of different length but having at least part thereof in common, the comparison is made on a cathode-ray tube (C.R.T.) with delayed sweep by superimposing the two displays of the waves received via the two paths, the two paths are travelled in respective half-cycles of a commutator cycle, and two delay generators are so controlled by the commutator that one provides the sweep delay and the other provides the differential delay #t needed to bring the two displays into coincidence on the C.R.T. time-base. In the Fig. 2 embodiment pulser 6 energizes transducer 7 once per half-cycle of commutator 5 and two-channel amplifier 9 is gated such that in alternate half-cycles the outputs of receiving transducers 8, 8<SP>1</SP> respectively are fed to the Y-plates of C.R.T. 10. Calibrated attenuators may be used for comparing the amplitudes of the two outputs. Sweep delay generator 13 enables a selected portion of the output to be displayed and calibrated delay generator 12 provides an additional sweep delay #t in those half-cycles where the longer path 7 to 8<SP>1</SP> is travelled in specimen 16. #t is thus a measure of the propagation characteristics over path l. Calibration markers 18, 20, may be used in calibrating the dial of delay generator 12. Transducer 7<SP>1</SP> may be used as transmitter for reversing the propagation direction so that measured values may be averaged to reduce acoustic coupling errors. In a second embodiment (Fig. 3, not shown) the delay #t is imparted to the transmission pulse in alternate half-cycles instead of to the sweep delay circuit. In third embodiment (Fig. 4, not shown), using two transmitters and one receiver, the transmitters are pulsed in respective half-cycles of the commutator, a single channel receiver amplifier is used, and the delay #t is imparted to the transmission pulse in alternate half-cycles. The invention enables propagation velocity, attenuation, wave dispersion and resonance oscillations to be studied.
