Abstract: A tensioning nut to secure a disk-shaped tool (6) is threadable onto the threaded spindle (5) of an electric tool, particularly an electric hand tool with run-out brake such as a right-angle grinder. The nut includes a nut body (1) provided with a corresponding thread, with a coaxially-positioned pressure ring (3) that may be tensioned with the disk-shaped tool (6).

Depending upon the wrapping angle (&agr;), the pitch (L) varies, which pitch increases in a first subdivision (T1) from the suction-side screw end, reaches a maximal value (Lmax) after one wrap, decreases in a second subdivision (T2) until a minimal value (Lmin), and is constant in a third subdivision (T3).

Abstract: An ion-exchange membrane has a mesh structure with microscopic pores in which water can infiltrate. When the ion-exchange membrane is incorporated in the sensor body, the one side of the membrane comes in contact with the sample solution and the other side thereof comes in contact with the internal solution. The water in the internal solution gradually migrates to the side of the sample flow path permeating through the membrane. When the sensor is used for extended periods of time, therefore, the sensor performance often decreases due to a decrease in the electric conductivity between the internal electrode and the ion-exchange membrane.
