Probe for the nondestructive testing of cylindrical cavities, including a rotatable testing head, an outwardly cylindrical housing supporting the testing head, a motor disposed in the housing for driving the testing head, a shell body being surrounded by the housing and being in the form of a semi-cylindrical part with a relatively smaller diameter in vicinity of the motor, a tube sealing the shell body in vicinity of the motor, and means disposed on the shell body for securing the motor in a definite position.

Probe for the nondestructive testing of cylindrical cavities, especially

Inspection device, including a probe having a thrust hose for moving the probe, the thrust hose having mutually equidistant holes formed therein along a generatrix line thereof, a feed device having drive wheels for engaging the thrust hose to move the probe, and plugs disposed on at least one of the drive wheels for insertion in the holes.

Inspection device, especially for steam generator tubes

A machine tool, especially a hand-held power tool, comprises a tool spindle and a clamping element turnably mounted on the spindle, in which the turnable clamping element is arrestable during rotation of the spindle for clamping or releasing a tool mounted thereon to thereby make a separate implement for preventing rotation of the clamping element during clamping or releasing the tool on the spindle unnecessary. In a special embodiment of the present invention the clamping or releasing forces during change of the tool are mechanically applied and the turning moment during clamping of the tool is limited to a predetermined value.

Machine tool, especially a hand-held power tool with a turnable clamping

A strain relief device, especially for power tools, has a pin upon which is pivotally mounted a clamping member with a spirally curved rough clamping surface which coacts with a second clamping surface. An electrical line is inserted between these surfaces and the clamping member is swung thereby applying a clamping force to the electrical line. When strains are applied to the line, the clamping member provides an increased clamping force by swiveling so that a section of the member of larger diameter presses the line against the second clamping surface. A lock mechanism is also provided to prevent the electrical line from being pushed further into the housing.
