摘要： The invention relates to a profiled tube for working cylinders without a piston rod having a cylinder chamber which extends in longitudinal direction and a piston guided movably therein and connected to pull means, and a carriage connected to the pull means and guided in a slide guide arranged on the profiled tube. In order to increase the torsional rigidity of a profiled tube for working cylinders having rodless pistons of this type, to guide the piston in a manner secured against turning and, at the same time, obtain a compact structural shape, the present invention provides a profiled tube have a closed single-piece cross section, that the cylinder chamber have an ovoid, preferably elliptical cross section arranged within the cross section of the profiled tube, that pressure-fluid guide channels extending in longitudinal direction are arranged within the cross section of the profiled tube, and that the slide guide is arranged along one of the outer longitudinal sides of the profiled tube and unitarily formed as a single piece with the tube.

摘要： An electrical apparatus is provided for use with a potentiometer or variable resistance element which does not require a mechanical connection between a contact member and an activating mechanism. This is accomplished by using a magnet in at least a portion of either the contact member or the activating mechanism while constructing at least a portion of the other of such contact member and the activating mechanism of a ferromagnetic material.

摘要： A device is disclosed for the selective clamping of an axially moveable or rotatable cylindrical shaft. The device disclosed may be either of a spring actuated-pressure release or a pressure actuated spring release embodiment. A clamping sleeve is located coaxially surrounding the cylindrical shaft to be immobilized. The clamping sleeve is separated into clamping elements at one end by longitudinal slots in the generally cylindrical sleeve. An actuating element is also arranged coaxially to the cylindrical body and the clamping sleeve and is mounted exterior to the clamping sleeve. The clamping elements are located radially inwardly from the actuating element and are separated therefrom by a series of bearings. The bearings engage the actuating element and the clamping elements through matched sets of inclined ramp elements. Each clamping element is provided with a set of bearings and ramp elements. The ramp elements are positioned such that their inclined faces are parallel to each other and each abutting the bearing. Longitudinal movement of the actuating element urges the inclined faces together, which are restrained by the bearings therebetween. The unyielding actuation element thus urges, through the bearings, the displaceable clamping elements against the surface of the cylindrical shaft.

摘要： An electropneumatic valve including a valve body and a proportional magnet connected thereto and having a unitary tappet having an integral valve disk disposed at one end and an armature of the proportional magnet disposed at an end longitudinally opposite thereto. The tappet and valve disk being formed of a nonmagnetic material and the valve body and proportional magnet are contactingly connected by complementary interlocking features.
