A toric finer-polisher for the fining and/or polishing of a toric lens comprises a lap table for holding a tool, a spindle on which the lap table is mounted, a rocker arm assembly for holding the lens in contact with the tool, and a motor for driving the spindle and lap table so as to cause relative motion between the tool and the lens, thereby finishing the surface of the lens. The spindle is fixed at its lower end to a gimbal, and is contacted at an intermediate point along the spindle by a timing belt connected to the motor, so as to maximize a gimbal radius of the lap table assembly, thus maintaining a parallel relationship between the tool axis and the lens axis during finishing of the lens surface. Other features of the invention include provision of all motions (rotational, orbital and transverse) by a single motor, provision of a two-spindle arrangement in which dual spindles are timed in their oscillatory motions so as to cancel normally encountered reactionary forces, provision of a gear reduction mechanism between the motor and a break-up motion assembly so as to provide break-up motion on a reduced-speed basis, and provision of a pressure-operated lap table for holding the tool on the lap table surface under the influence of air pressure.

A modular passive solar energy storage system comprises a plurality of heat tubes which are arranged to form a flat plate solar collector and are releasably connected to a water reservoir by, and are part of, double-walled heat exchangers which penetrate to the water reservoir and enhance the heat transfer characteristics between the collector and the reservoir. The flat plate collector-heat exchanger disassembly, the collector housing, and the reservoir are integrated into a relatively light weight, unitary structural system in which the reservoir is a primary structural element. In addition to light weight, the system features high efficiency and ease of assembly and maintenance.

An apparatus for finishing toric surfaces of ophthalmic lenses. The apparatus includes a frame and a first assembly for providing an orbital, break-up motion to a lapping tool having a polishing surface of a selected base curve and cross curve. A second assembly is also mounted upon the frame for providing an orbital, break-up motion to a lens to be finished. Adjustment means are provided for selectively adjusting the amplitude of the orbital, break-up motion of both the lapping tool and the lens.
