Abstract: A computer-based microingredient inventory accounting system and process for use with programmable microingredient dispensing and mixing machinery. In the illustrative embodiment, the computer-based microingredient inventory accounting system is coupled with a programmable microingredient dispensing and mixing system. The programmable microingredient dispensing and mixing system includes weight measuring mechanisms that are interfaced with a computer system programmed to continuously monitor the weight of microingredients stored on a plurality of inventory storage scales, as well as in a plurality of dispensing bins and tanks. The computer-based microingredient inventory accounting system is programmed to perform a number of inventory monitoring functions including: automated detection of microingredient loss (e.g.

Abstract: A solar heating system with one or more collector panels having an insulative, fiberglass top, black, heat-producing plates and an air manifold at each end. Cold air is transmitted through a manifold, across the plates and out the other manifold. The heated air is directed to a heat-storage compartment in which heat is stored in containers of wax.

Abstract: A window unit for heating a room with solar heat comprising a heat collector section and a heat storage section. A three position fan directs air either from the collector to the interior, from the collector to the store, or from the store to the interior.
