Abstract: An assembly forms a seal between components (11, 33) having sealing zones (37,51). The sealing zones face each other in a functional position of the components. A sealing element (43, 57) is on the sealing zone (37, 51) of one component (11, 33). A sealing surface (51) is on the sealing zone (37, 51) of the other component (11, 33) to form a radial seal. The components (11, 33) can be brought into the functional position by a relative movement in the axial direction. The sealing element (43, 57) sealingly interacts with the sealing surface (51) in the functional position. A third component (61) associated with an actuating part (62) acts on the sealing element (43;57) in the functional position of the components (11, 33) to deform the element to increase the sealing force.

Abstract: An apparatus comprises a frame, a vehicle engagement assembly, a lift actuation assembly, a locking assembly, and an indicator system. The vehicle engagement assembly is designed to vertically lift a vehicle. The frame comprises at least one slot to provide a predetermined path for the vehicle engagement assembly. The lift assembly provides the force required to lift the vehicle while the locking assembly stabilizes the vehicles without further force required by the lift assembly. The indicator system determines whether the locking assembly or the lift assembly is predominantly keeping the vehicle lifted.

Abstract: A carpentry tool for pushing deck, flooring or other boards toward one another on a joist or underlying substructure. The tool can be operated with one hand, leaving the other hand free for installation of a fastener. The tool can leave an area adjacent the joist and board exposed so that a fastener can be installed in the board and joist in that area.
