Abstract: A spring-loaded dampening actuator includes a cylindrically-shaped body member, a piston rod, a coil spring, and a one-way lip seal member. The lip seal member engages an inner sidewall of the body member only when a force is applied by means of a coil spring so as to push the piston rod out from the body member at a dampened or controlled rate of speed.

Abstract: A spin welded fastening assembly is constructed of two interfitting components. A circular base member formed of thermoplastic material has a circular disc portion with a workpiece engaging surface for friction welding and has a circular upstanding coupler portion integrally formed on the opposite surface of the disc portion for mounting a standoff member. The standoff member has a downwardly extending circular flange portion which snaps over the upstanding circular coupler portion of the circular base member. The circular flange portion of the standoff member has a closed end in the form of a transversely extending mounting plate portion having a central mounting aperture formed therethrough. The head of a quarter turn type fastener is installed in the mounting aperture of the standoff member.
