摘要:
Reactive dyestuffs of the formula ##STR1## in which Q and P are hydrogen or sulfonic acid but cannot simultaneously have the same meaning; andD is a radical of an aromatic-carbocyclic or aromatic-heterocyclic diazo component which contains a reactive group; are disclosed. These are useful for the dyeing and printing of materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk and synthetic polyamide and polyurethane fibres, and for the wash-fast dyeing and printing of natural or regenerated cellulose, the treatment of cellulose materials being appropriately carried out in the presence of acid-binding agents and if appropriate by the action of heat, in accordance with the known processes for reactive dyestuffs.
摘要:
The invention relates to valuable new reactive dyestuffs of the general formula ##SPC1##In which A stands for hydrogen, a methyl, phenyl, lower carbalkoxy, optionally substituted carboxamide or a carboxy group; B denotes a carboxy, lower carbalkoxy, optionally substituted carboxamide or nitrile group; Z means a hydroxy or amino group; R.sub.1 and R.sub.2 stand for identical or different radicals such as hydrogen or methyl; D denotes the radical of a diazo component containing a reactive group; and n means the number 0 or 1; which are suitable for the dyeing and printing of materials containing hydroxyl or amide groups and for dyeing natural or regenerated cellulose fast to washing.

A rotating chip removing tool, such as a drilling and chamfering tool, and a milling cutter, each of which have at least one cutting insert or cutting plate. The cutting plate has a guide recess that adjoins the underside of the cutting plate. A plate seat for accommodating the cutting plate is provided on a tool body of the chip removing tool and has a guide fillet or surface which corresponds to the guide recess.
摘要:
A rotary tool for drilling and chamfering, which takes place in one common advance, essentially comprises a base body, a drill clamped centered therein and a chamfering tool disposed on the end of the base body toward the drill tip and having a cutter body tip disposed next to the flank of the lateral free face of the drill. The chamfering tool can be radially adjusted in relation to the drill in a direction pointing at right angles in respect to the drill axis.

Azo class reactive dyestuffs have been found which have the general formula (1) ##STR1## and in which Z.sup.1 and Z.sup.2 represent a reactive group from the pyrimidine series, X represents SR.sup.1, OR.sup.2 or NR.sup.3 R.sup.4, and the remaining substituents have the meanings given in the description, which dyestuffs are particularly suitable for dyeing hydroxyl- and amido-containing fibres, in particular cotton.
摘要:
A gearing is described for locks of panic doors. The gearing has a first gearing part (17)which is rotatable around a first axis (17a) and can be connected with an actuating member (18) for a lock nut or the like, and a second gearing part (28) which is rotatable around a second axis perpendicular to the first axis and is connected with a handle (1). One of the gear parts is provided with a driver pin (24) arranged parallel to and at a distance from the first axis and the other gearing part is provided with a guide part cooperating with the latter for the purpose of converting the rotating movement of the handle (1) into a rotating movement of the actuating member (18).
摘要:
New reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein the substituents have the meaning given in the description, are suitable for dyeing and printing materials containing hydroxyl groups or amide groups, in particular cellulose materials.
摘要:
The invention relates to an improved process for the preparation of dyestuffs based on at least one triphendioxazine which is linked to a further chromophore via a triazine at a pH of 5.5 to 2.0 and a temperature of 50 to 100.degree. C.
摘要:
Dyestuffs of the formula ##STR1## with the substituent meanings mentioned in the description, are suitable for dyeing and printing hydroxyl- and amido-containing textile materials. To prepare these dyestuffs, new intermediates of the formula ##STR2## are used.
摘要:
New monofluorotriazinyl compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 can be identical or different and represent a hydrocarbon radical with 12 to 24 C atoms andX represents an oxygen atom, a sulphur atom or the group NR.sup.3,whereinR.sup.3 denotes hydrogen or a hydrocarbon radical with 1 to 24 C atoms.In formula (1), the hydrocarbon radicals R.sup.1 and R.sup.2 preferably represent linear or branched alkyl (C.sub.12 -C.sub.24), cycloalkyl (C.sub.12 -C.sub.24) or aromatic radicals with fused-on hydroaromatic systems with 12 to 24 C atoms. The hydrocarbon radical R.sup.3 is preferably one of the abovementioned substituents or methyl.The compounds of the formula (1) are suitable as effective components in reactive sizing agents for paper.
