Abstract: The performance of an eddy current brake is controlled by controlling the magnetic flux in its housing by changing the energizing voltage of the energizing coil of the brake in accordance with a signal obtained by comparing a signal representative of the desired brake performance with a signal representative of the actual magnetic flux measured in the housing at a location of substantially homogeneous flux distribution. The desired performance signal may be a signal representative of the difference between a desired rotational speed signal and the actual rotational speed signal, or it may be a signal representative of the difference between a desired torque signal and an actual torque signal. The desired performance signal may also be a signal representative of the difference between a signal obtained by comparing desired and actual rotational speed signals with a signal representative of actual torque. A Hall generator is used to measure actual flux.

In order to facilitate the mounting of the pretensioned spring element, a bearing body is provided to hold the spring element on at least one of the two hinge parts.

Abstract: A reinforcing sleeve of plastic or a similar material for the ends of hard paper reel cores or the like which form the support cores for wound goods such as paper, foils, textiles or the like. The sleeve comprises a collar adapted to rest against the end faces of the reel core and a radial, hollow projection integrated with the collar and the outer periphery of the sleeve, the projection being adapted to engage one end face of the reel core and to house a driver system. A reinforcing ring is integrated in the collar and comprises a radially extending receiving element for the driver system, the receiving element being integrated in the radial projection and reinforcing it.

Abstract: In an apparatus for the continuous pressing and decatizing of fabric, a pressure belt serves to move a fabric undergoing treatment around a rotatably-mounted and heatable cylinder. The pressure belt directly contacts the fabric to press it against the cylinder. The surface of the pressure belt is arranged to be heated by a heating roller around which the belt passes prior to passage around the cylinder. The cylinder and heating roller can be independently heated to different temperatures to produce a temperature differential across the fabric as it is pressed. As a result, moisture condensation preferentially occurs on one side of the fabric causing luster reduction on that side of the fabric.

Abstract: A filter centrifuge for the separation of solid and liquid components in a suspension in which a filter cloth is used. The filter cloth is inserted in the drum of the centrifuge and is removably fastened at one side about the periphery of an aperture in the drum. The filter cloth is flexible and may be turned inside out to discharge solid materials after the centrifuging operation. To prevent the flexible filter cloth from becoming pressed into the openings of the centrifuge drum by the force of the centrifuging process and the weight of the solid material, a supporting screen is inserted between the inner wall and the drum of the filter cloth. The screen is in the form of longitudinal rods from which the filter cloth is easily removed even if the gaps between the rods are penetrated to a slight extent.
