A method and apparatus for recycling cans is disclosed. Discrimination of overweight conductive material from acceptable conductive materials from a mixed material input, while maintaining a high level of acceptable material recovery is achieved by control of the input to the separation system, as well as control of the separation mechanism.

Method for recycling cans

Machine for receiving used cans

A method and apparatus for recycling cans is disclosed. Magnetic material comprising mostly steel cans is separated from a material input. Conductive material, comprising mostly aluminum cans, is then separated from the balance of the material input. The conductive material is weighed and paid for and the magnetic material and conductive material are recombined for storage.

A solar liquid-to-liquid heat exchanger, method of making the same, and hot water heating apparatus employing same are provided wherein such heat exchanger is comprised of a first tubular member made of a heat conductive tube material and having a plurality of turns, a second tubular member made of a heat conductive tube material and having a plurality of turns which correspond to and are fixed against the turns of the first member to provide a strong mechanical and thermal connection between immediately adjacent faces of associated member turns. The fixing of the turns of the members and utilization of the heat exchanger in a hot water heating apparatus with flow of a solar fluid used in such apparatus in one direction through the first tubular member and water to be heated through the second tubular member in counterflow to the one direction assures optimum transfer of heat from the solar fluid to the water to be heated.

Method of making a solar heat exchanger

A solar collector is provided comprising a cover assembly which employs a flexible polymeric cover sheet and means for stretching the cover sheet and maintaining it taut under various ambient temperature conditions, a simple and economical peripheral supporting structure, and support means for a solar heat exchanger of the solar collector which supports such heat exchanger in a high strength manner yet in thermally insulated relation.

Solar collector

A ball bat is provided and comprises a tubular metallic body having a hitting portion and a handle portion with the handle portion terminating in an outer end portion having a pair of aligned holes therein. The bat has a disc-like knob having spaced outer and inner end surfaces interconnected by an outwardly convex rounded edge portion with the knob having an opening extending therein from its inner surface toward its outer surface and having a pair of aligned holes therein. The outer end portion of the handle portion is disposed in the opening with the holes in the knob being disposed in aligned relation with the holes in the outer end portion and a pin extends through the holes in the outer end portion and the holes in the knob to hold the knob fixed to the handle portion.
