Abstract: A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

Abstract: Door drive for a door of a building with a door panel supported pivotably in a fixed door frame about a vertical door axis, in door hinges, with a main drive and an auxiliary drive. The output of the drive unit of the auxiliary drive is or can be coupled to the slider and/or slide arm of the main drive via a coupling device connected in between in order to act on the slider and/or slide arm of the main drive at least in an end phase of the closing process and/or at least an initial phase of the opening process.

Abstract: A door drive mechanism includes a main drive and an auxiliary drive. In this connection it is provided that the components of the main drive and of the auxiliary drive to be mounted on the door leaf side are borne in or on a common and/or continuous housing mechanism and/or bearing framework mechanism and/or mounting plate mechanism to be mounted on the door leaf side and/or are covered by a common and/or continuous cover to be mounted on the door leaf side.

Abstract: A door drive mechanism includes a main drive and an auxiliary drive. In this connection it is provided that the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output and that the drive assembly of the auxiliary drive is borne in a pivot bearing and that the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail.

Abstract: A drive system for a moveable wing, especially for a door or a window, is described. The drive system includes at least one energy storage device by whose discharge of energy the wing is moved. The energy storage device is hereby controllable in its energy discharge by means of a control system. The control system has an electrically controllable control element. The motion of the wing is directly or indirectly detected by a sensor, whose output signal is fed into a regulating device, which controls the control element. The regulating device is realized in a way, that the influence of the control element, dependent on the motion of the wing, can change the energy discharge of the energy storage device.

Abstract: An attachment element is provided for securing a sensor-type connection component (5) to an attachment point (7). The connection component (5) penetrates a part of a wall (4) of a tube-shaped component (2). The attachment element (12) partially surrounds the connection component (5).

Abstract: A sliding door system is provided which has a support frame including vertical posts and a horizontal transom. An assembly supporting a sliding door wing is supported at the support frame and includes a running mechanism operable to carry the door wing disposed in a running mechanism housing. A drive motor assembly disposed in a drive motor assembly housing is operably connected to the running mechanism to move the door wing. The running mechanism housing and the drive motor assembly housing are disposed one behind the other in a direction transverse to the transom and door wing and are configured and dimensioned to form a parallelepiped with a vertical height fitting within a vertical height of the transom.
