Abstract: A vehicle seat adjusting apparatus for adjusting the angle of inclination of a seat and thereby adjusting passenger height and available leg room by rotating the seat about a single, centrally located, transverse or lateral axis. A latch mechanism normally holds the seat relative to the seat track rails. Release of the latch mechanism is effected through a manual lever at the outside of one seat rail. The lever draws a release assembly laterally of the seat to slide a release arm longitudinally of the seat. The seat may then be notched to a desired position with the aid of a bias spring assisting the seat movement. Release of the lever allows the latch mechanism bias to restore the latch action in the desired position. By using a central pivot, you adjust the attitude of the seat and, by virture of the motion pattern, the rear of the seat moves up or down thus raising or lowering the occupants eye level in the vehicle.

Abstract: A solar energy collection system is provided in which a parabolic trough is oriented by a drive mechanism to reflect the rays of the sun onto an energy collector located at the parabolic focus. The system is constructed to track the sun to maintain focusing of reflected solar radiation during daylight hours. A counterweight is employed in association with the drive mechanism to effectuate tracking and to maintain gravitational equilibrium of the reflector trough despite changes in elevation of the center of the gravity of the trough. Shock absorbers are provided which inhibit disorientation of the trough by gusts of wind, yet which allow the trough to track the sun. Coaxial construction of the solar energy collector with an evacuated sleeve of parabolic configuration positioned thereabout allows a heat collection medium to circulate in the collector, yet minimizes radiant heat loss.

Abstract: A projector tilt mechanism includes a base about which a load-carrying platform is rotated in a vertical plane. A threaded shaft is rotatably coupled to the platform by radial thrust bearings and to the base by threaded fittings. Lost motion in the rotational system is avoided by properly positioning and locking in place two threaded nuts along the shaft at either side of the threaded connection to the base, and by using threaded locking collars tightened against the outermost thrust bearing faces. Rotation of the shaft produces relative rotation of the platform and base, causing the base to raise the front or rear of the projector above a flat surface or, if the base is affixed to a pedestal, causing a direct change in platform pitch.
