    摘要： A test system and a corresponding method for testing the seal of a glove which is installed in a port of an isolator, including a test disc which can be connected in a hermetically sealed fashion to the port. The glove and test disc define a sealed glove volume which can be placed under excess pressure. The test disc has a pressure-measuring device with a microprocessor and a memory for recording and storing a pressure profile in the glove volume and a data interface. The glove and port have identification elements which are read by a reading device of the test disc and information concerning the pressure profile along with the identities of the glove and port are transmitted wirelessly to an evaluation unit which estimates and records a residual period of use of the glove. A plurality of gloves in ports can be tested simultaneously.

    摘要： The invention relates to a test disc system having at least one test disc for testing the seal of a glove which is installed in a port of an insulator. The test disc (1) can be connected in a hermetically sealed fashion to the port, wherein the glove encloses with the test disc (1) a glove volume which can be placed under overpressure by the test disc (1). The test disc (1) has a base body in which electronic components for recording and storing a pressure profile in the glove volume, and at least one data interface are arranged. The test disc (1) also has a reading device for reading both a first identification element which is arranged on the glove and a second identification element which is assigned to the port.

    摘要： The present invention relates to a process for preparing sulfuric diamides of the general formula I R1R2N—S(O)2—NH2  (I) in which R1 and R2 are each independently a primary alkyl radical having from 1 to 8 carbon atoms, a secondary alkyl radical having from 3 to 8 carbon atoms or a cycloalkyl radical having from 5 to 8 carbon atoms, or, together with the nitrogen atom, form a 5- to 8-membered, saturated nitrogen heterocycle which, as well as the nitrogen atom, may have a further heteroatom selected from O and S as a ring member, where the nitrogen heterocycle is unsubstituted or may have 1, 2, 3 or 4 alkyl groups having in each case from 1 to 4 carbon atoms as substituents. The process comprises the following steps: i) the reaction of a secondary amine of the formula II R1R2NH  (II)  in which R1 and R2 are each as defined above with sulfuryl chloride in an inert solvent, especially an aromatic solvent, in the presence of a tertiary amine to give a sulfamoyl chloride of the formula III R1R2N—S(O)2—Cl  (III)  in which R1 and R2 are each as defined above, and ii) reaction of the sulfamoyl chloride of the formula III obtained in step i) with ammonia, the sulfamoyl chloride of the formula III being used in step ii) in the form of the solution obtained in step i) in the inert solvent, especially the aromatic solvent.
