Abstract: A clamping or chucking tool for clamping a test sample in a testing machine has a clamping housing for applying a wedging action to the sample with the aid of one or two clamping jaws that are activated by an operating member that is inserted into the clamping housing and axially displaceable in the clamping housing. The clamping jaws are slidingly guided in a V-groove of the operating member but are stationary in the axial direction of the clamping housing, while the operating member is movable axially relative to the clamping housing for imparting to the clamping jaws a radial movement component perpendicularly to the longitudinal axis of the test sample. Lateral guide arms engage respective guide grooves in the clamping jaws to hold the clamping jaws against axial movement while permitting the radial movement. The clamping housing and the operating member are provided with at least one lateral opening for a rapid insertion of the test sample laterally into the clamping housing. This type of construction provides a chucking tool for holding test samples that may be exposed to tension loads, or to compression loads and/or to torque loads.

Abstract: The present differential pressure limiting valve is constructed with an axially movable valve body having hydrostatic bearings including bearing shafts, whereby the bearing shafts are connected to opposite sides of said valve body in axial alignment. Normally the valve body is biased against the valve seat by an adjustable closing spring acting on the bearing shaft or valve body opposite the valve seat to close the valve. In addition, the face end of the bearing shaft opposite the valve seat may be loaded by a pressure medium. The respective diameters of the bearings may differ. However, the effective cross-sections of the valve body are preferally equal on both sides of the valve seat. The present unidirectionally effective valves are especially suitable for use in a parallel circuit, wherein one valve is effective for pressure relief in one flow direction whereas the parallel valve is effective for pressure relief in the opposite flow direction, whereby pressure relief may be provided, for example, for both chambers of a dual acting piston drive cylinder arrangement.

Abstract: The present mechanical chucking device especially for a testing apparatus, has a friction reducing layer interposed between the clamping members and a base plate and another friction reducing layer interposed between the base plate and securing elements for the clamping members, whereby said clamping members may slide within a given range along the base plate without having to release the securing elements holding said clamping members to the base plate. The clamping members are driven by a spindle movably held in a guide block on the base plate which allows an exact concentric clamping of the sample.

Abstract: A hydraulic displacement machine that can operate as a pump or a motor in connection with an electrorheologic or magnetorheologic fluid includes a housing, a rotary piston arranged to rotate within a chamber in the housing, at least one displacement vane provided on the rotary piston, a plurality of field generating elements such as capacitor plate segments and/or coil arrangements that are each individually electrically energizable and that are arranged on the two sidewalls of the housing chamber distributed around the circumferential direction, and an actuator connected to each field generating element so as to move the elements of each pair selectively closer together and farther apart from each other. By applying an appropriate electric or magnetic field to the electrorheologic or magnetorheologic fluid between the field generating elements, the fluid is locally solidified in the "flow mode" to form a stationary seal plug within each fluid chamber between respective consecutive vanes. By moving the field generating elements of each pair closer together, the seal blockage is further solidified so as to additionally achieve a "squeeze mode" effect in the fluid.

Abstract: The ultimate tensile strength of a test sample is tested in a high speed testing machine having a frame (2), a force measuring device (9A), and a load application mechanism (3, 4) for applying a loading stroke to the test sample after a loading piston has passed through a lead stroke to attain the required testing velocity. A force locking, frictionally effective clamping mechanism clamps the test sample for coupling to the machine frame (2) and/or to the load application mechanism (3) when the loading piston has reached the testing velocity.
