Abstract: A viscous fluid pump is provided. The pump has a housing that has an inlet for receiving viscous fluid and an outlet for dispensing viscous fluid. A bushing within the housing has an opening proximate the inlet and which provides access into an inner chamber of the bushing. The opening extends beyond the inlet in a direction orthogonal to the longitudinal dimension of the pump. A piston is movable within the inner chamber, with the piston having a first position in which the inlet is in fluid communication with the inner chamber through the opening and a second position in which the inlet is not in fluid communication with the inner chamber. The housing may define an interior, with the interior of the housing being free of soft seals.

Abstract: A drill insert is provided for coupling a step or hook to a structure. The insert has a gripping portion configured to engage the step or hook, and a supporting portion. The supporting portion has an interior channel for slidably receiving the gripping portion and an elongate end that is configured for insertion into the chuck of a drill and which extends along a longitudinal axis. The gripping and supporting portions are slideable relative to one another along the longitudinal axis, with selective sliding motion between the gripping and supporting portions being effective to selectively lock and release the step or hook relative to the insert.
