Abstract:
In a pneumatic damper for slowing down movable furniture parts, comprising a cylinder and a piston movably disposed in the cylinder so as to form a displacement chamber at one side and a vacuum chamber at the other side of the piston, the piston includes a seal element which, in one end position thereof, is in close contact with the wall of the cylinder whose cross-section increases toward the opposite end of the cylinder so that the sealing effect collapses when the piston approaches its other end position and the piston includes a piston rod, which has a diameter of less than 35% of the piston diameter and sealingly extends through a cylinder end wall.
Abstract:
In a brake- and/or clamping arrangement for a shaft supported in an apparatus housing or a device housing and comprising a braking disc mounted on the shaft rigidly for rotation therewith and a clamping ring supported in the device housing, the braking disc has a friction area comprising two truncated cone-shaped friction surfaces with at least one brake cone arranged in the device housing and one arranged on an activating member. One brake cone abuts during braking or clamping the brake disc whereas the other cone abuts a clamping ring, which is disposed between the contact areas of the brake cones, the clamping ring are in contact with each other being mounted to the apparatus housing.
Abstract:
In a combined deceleration and acceleration device for the controlled closing and opening of, for example, furniture parts, a base part consisting of a cylinder and a guide structure is provided wherein a drag element is movably supported by the guide structure, and a piston with a piston rod is connected to the drag element which has a park position remote from the cylinder and is biased by an energy storage structure toward the cylinder for moving the piston into the cylinder in a controlled decelerating manner while carrying along the drag element and a movable part engaged with the drag element.

In a damping mechanism for a pivot door arranged in a door frame, comprising a door fixture arranged in or on the door panel, a frame fixture arranged in or on the door frame, a damper arrangement arranged in the door fixture or the frame fixture and a damper arrangement counter part mounted in the frame fixture or in the door fixture, a damper arrangement with a brake catcher provided with a damper member includes a spring element which pulls the brake catcher into the fixture and the damper arrangement counter part includes at least one trigger element which is abutted by the brake catcher during closing of the door, so that the damper arrangement begins to dampen the pivot movement of the door as soon as a fixture part of the door comes into contact with a fixture part of the door frame.
Abstract:
In a friction brake arrangement with emergency braking functions for use with a carriage supported on a guide track, with a friction clamping structure including a friction shoe supported in a housing so as to be disposed adjacent the guide track, a spring element is provided biasing the friction shoe toward the guide track for frictional engagement therewith and also a power operated drive for disengaging the friction shoe from the guide track against the force of the spring element and, furthermore, a blocking member is disposed between the drive means and the spring element and held electromagnetically in the blocking position so that the spring is released and the carriage is locked to the guide track for example upon occurrence of a power outage.
Abstract:
In an anchor for the attachment to flat building components including two cover plates and an intermediate support core layer wherein the anchor comprises an expansion body and a wedge body which is inserted into the expansion body and includes an opening for inserting a mounting means, the installed anchor is disposed in an opening of the building component which extends through one cover plate and the intermediate support core plate and into a dead end bore of the other cover plate. The expansion body has spreadable engagement elements, wherein, with the anchor installed, one cylinder zone is in contact with the bore wall of the first cover plate, and a wedging zone spreads out the expansion body in the intermediate support core and in the dead end bore of the second cover plate.
Abstract:
The invention concerns a pneumatic retarding device with a cylinder dividing the cylinder into a displacement chamber and a compensation chamber and including a piston with a piston rod movably supported in the cylinder and having a piston seal element wherein, upon movement of the piston, a piston movement opposing force is generated while an air leakage flow is established past the piston for damping piston movement. The piston and the piston rod are formed integrally and the piston seal element has at least two deformation zones of which one responds faster to a pressure change in the displacement chamber then the other which is subjected to the pressure change via a restrictive passage. Also, a guide system is provided with such a retarding device.
Abstract:
In a door closing mechanism for a hinged door arranged in a door frame, comprising a door fixture mounted to the door frame, a final door closing pull arrangement disposed in the door- or the frame fixture and a door closing pull arrangement counter part mounted on the frame, or respectively, the door fixture, the final door closing mechanism includes a catcher with a closing pull element which is moved toward a front position in which it is retained. A closing pull mechanism counter piece has a trigger element with which the closing pull element comes directly or indirectly into contact during door closing for pulling the to a closed position.
Abstract:
A circuit and a method for measuring a quantity influencing the capacitance-voltage characteristic of a capacitive element, the measuring accuracy and the signal-to-noise-ratio being improved by determining such quantity on the basis of the area under the curve of the capacitance-voltage characteristic.
Abstract:
A micromechanical component having a carrier and a deformable element of a flat design disposed parallel to a surface of the carrier, with the deformable element being provided with a mechano-electric signal converter. The carrier and the deformable element are fabricated in one piece out of a semiconductor substrate and are electrically insulated from one another, with the insulation being obtained by a buried layer produced by ion implantation thereby providing a micromechanical component which is suitable for joint integration with electric circuits in CMOS technology.
