Abstract: The current invention provides methods and apparatus for integrating a high temperature waste heat recovery system with a chemical or refining process which requires heat energy at a temperature less than the operational temperature of the waste heat recovery system. Additionally, the current invention provides methods and apparatus suitable for retrofitting existing process units requiring heat energy at a temperature of T2 with a waste heat recovery system operating at temperature of T1 where T1 is greater than T2.

Abstract: A system for recovering energy from the natural and man made sources of wind, water and sunshine provides within a given local area wind, water and solar apparatuses for converting all three wind, water and solar energies to electrical power to provide a reasonably steady supply of electrical power at all times. The wind and water apparatuses may be double speed Savonius rotor electrical generating apparatuses each of which includes two Savonius type rotors mounted adjacent to one another for rotation about a common axis with the blades of the rotor units being arranged so that the rotor units rotate in opposite directions relative to one another under the influence of a given wind or flow of water.

Abstract: A foldable posting board has a plurality of hingedly connected panels. Resilient wire loop bindings connected to the panels extend along side edges of the panels and define vertical columns of mounting posts which project through and cooperate with apertures in a record sheet to retain the sheet in a predetermined position relative to the panels. Apertured forms received on the posts are retained in overlying registry with the record sheet. One of the bindings forms a hinge for the panels.

Abstract: A posting tray, or similar record holding tray, includes two side rails which are adjustably movable toward and away from one another, and are releasably fixable in any given position of adjustment, to suit the tray for record cards of various different widths. Each side rail is part of a C-shaped member having two laterally inwardly extending legs at its opposite ends. The legs are connected to the front and rear walls of the tray. The two legs associated with each wall overlap one another throughout a portion of the range of adjustable movement of the side rails, and are out of such overlapping relationship throughout another portion of the range of adjustable movement, to maximize the side rail spacing variation range. The overlap of the legs which does occur may be accommodated in either the vertical plane or the horizontal plane.
