Abstract: A food storage building (10) having exterior wall surface (55) and exterior ceiling surfaces (65) held in spaced relationship with interior wall surfaces (64) and interior ceiling surfaces (64) to form interconnecting between wall and between wall cavities. Ventilation duct (41) is positioned within the between wall cavities around the base perimeter of wall systems (11). The ventilation duct (41) has a plurality of vent holes (42) for supplying heated or cooled forced air from heat source (40) to the between wall cavities for purposes of holding interior wall surfaces (54) and interior ceiling surfaces (64) above the drew point for the interior atmospheric conditions of food storage building (10).

Abstract: A modular floor sub-structure is provided wherein discrete floor modules having bottom surfaces and sides extending upwardly to support paired floor tile are interconnected to sit upon a floor surface and, in turn, support rack-mounted computer components. Select ones of the floor modules contain air cooling coils and blowers, while others are provided with uninterrupted power supplies and still others retain power distribution networks. The cooling system of a given module as well as the UPS components of another given module are provided having a capacity for supporting one computer component. Where more than one computer component is to be supported by the system, then additional modules are provided to develop an expanded elevated floor surface with power and heat removal servicing specific to each computer component.

Abstract: A smoker's booth for isolating, containing, venting, and filtering tobacco smoke. The booth has a walled enclosure with a modular room divider system using hollow walls, filtration, and blower devices to remove tobacco smoke from workplace air.

Abstract: A room comprise of localized region (10) for air conditioning wherein conditioned air or totally fresh air can be directed to certain region of the room. A path of air flow may comprised of a ceiling air collector/distributor (80) joining with a floor air collector/distributor (41) by a duct (18) having the localized air conditioning region (10) link the floor air collector/distributor to the ceiling air collector/distributor to complete the circuit while maintaining the characteristic of air conditioning specific portion of the room only but not the whole room.

Abstract: In a composting process, a heat conductive ventilation hood overlying a compost pile undergoing active composting. The hood is shaped so that process air emanating from the pile contacts the undersurface of the hood while ambient outside cool air is caused to traverse the upper surface of the hood. As a result of this heat exchange arrangement process air is dehumidified while concomitantly the ambient air is heated. The hood is pitched to cause condensate to run down its surface and not to drip. Warmed ambient air is used to heat the composting facility and dehumidified process air and condensate is reused in the composting process.
