Abstract: A long travel lift system, apparatus, and method enables users to raise a structural cap from a structural bottom for creating a fillable space between the structural cap and structural bottom for receiving a second, cap-supporting construction intermediate the structural cap and structural bottom. The long travel lift system incorporates a series lift apparatuses, each of which include a telescopic tube construction and winch assembly for imparting a lift force to an inner tube of the telescopic tube construction for extending the inner tube relative to an outer tube. The load lifting force is transmitted to the inner tube from the winch assembly via a pulley assembly and lengthwise slot formed in the outer tube of the tube construction. The outer tube is reinforced with various structures in view of the slot formation. The winch assembly is outfitted with a transmission for enhancing rotational speed of the winch assembly.

Abstract: A room ventilation system, apparatus, and method enable a user to selectively ventilate a room, and incorporate the use of a tubular vent assembly. The tubular vent assembly has an apertured outer tube construction, and an apertured inner tube construction. The outer tube construction has fixed apertures. Upper convex surfacing of the outer tube construction is fixedly attached to an upper assembly-fixing construction, and lower convex surfacing is fixedly attached to a lower assembly-fixing construction. The inner tube construction has rotatable apertures insofar as the inner tube construction is rotatable relative to the outer tube construction for aligning the rotatable apertures with the fixed apertures for selectively enabling an air current to pass intermediate the room interior and the room exterior for ventilating the room interior. A lever arm and a lever-letting slot provide the user with cooperable structure for selectively adjusting the rotatable apertures.
