Abstract: The invention relates to a safety switch arrangement for switching the power supply of a tool on and off by means of at least two actuators. The actuators are connected to a code generator. The code generator can issue a numerical word divided into two partial words, the values of which can be influenced by a respective one of the at least two actuators. If the actuators are activated, the values for the partial words are changed continuously. As a result of the deactivation of an actuator, the assigned partial word assumes a fixed, predetermined value. In order to check the switching states of the actuators, the partial words are read synchronously into an evaluation unit. The power supply of the tool is switched “on” only when the at least two actuators are activated to the “on” state and the partial words correspond to the predetermined fixed value.

Abstract: The present invention relates to a process for the treatment of lyocell cellulose fibers which comprises treating the lyocell cellulose fibers with at least one compound of the formula wherein R1 and R2 are each independently of the other halogen or a sulfo-substituted phenylamino radical, at least one of the two substituents R1 and R2 being halogen, R3 and R4 are each independently of the other unsubstituted phenyl or phenyl substituted by C1-C4alkyl, C1-C4alkoxy, acylamino, sulfo, —SO2—CH═CH2, —SO2—CH2CH2—OSO3H, —NH—CO—CBr═CH2 or by —NH—CO—CHBr—CH2Br, A1 and A2 are each independently of the other —O—, —S— or —NR5—, wherein R5 is hydrogen or C1-C4alkyl, A3 and A4 are each independently of the other —O—, —S— or —NR5—, or —A3—R3 is halogen and/or —A4—R4 is halogen, wherein R5 is hydrogen or C1-C4alkyl and B is an
