Azo reactive dyestuffs have the following formula D.sup.1 --N.dbd.N--K.sup.1 --Y--K.sup.2 --N.dbd.N--D.sup.2 (1) where the radicals D.sup.1 and D.sup.2 are identical or different and are the radical of a diazo component of the formula XSO.sub.2 --B--D-- (2).
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.

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.
摘要:
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:
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.
