Abstract: A moisture metering calibration method and system for, e.g., determining the moisture lumber within a lumber drying kiln is disclosed. Calibration of moisture indicative electrical signals obtained from, e.g., moisture sensing capacitive plates spaced apart within a stack of drying lumber is performed, wherein long lengths (e.g., up to 1000 linear feet or more) of coaxial cable can be used for transmitting the signals, and effectively removing signal anomalies induced in such cabling so that accurate lumber moisture measurements result. Such extended cable lengths provides flexibility with respect to placement of electronic moisture metering equipment. This flexibility allows such equipment to be placed in an environmentally-controlled enclosure, rather than on the weather exposed exterior of a kiln whose lumber is being monitored.

Abstract: A system and method are provided for controllably drying moisture-containing work pieces. The system comprises a drying compartment defining an internal workspace for housing and drying the moisture-containing work pieces by introducing heat into the internal workspace and heating the moisture-containing work pieces located in the internal workspace by removing heated moisture from the work pieces and absorbing the heated moisture into the air in the workspace to produce heated humidified air. A multi-directional air flow heat exchanger is employed for receiving heated humidified air and atmospheric air and for recycling waste heat from exhaust air from the drying compartment, and for heating the atmospheric air in the heat exchanger using recovered heat extracted from the heated humidified air to a temperature higher than ambient temperature thereby reducing energy costs and drying time and preventing the loss of circulation air.

Abstract: In drying the interior of an indoor unit, room humidity (Rh) is detected by a humidity sensor, and a drying operation cycle, in which after first heating operation, which is weak heating operation in which a compressor included in a refrigerating cycle is operated at a low rotational speed, has been performed for a predetermined period of time, second heating operation, which is heating operation close to air blowing operation in which the compressor is stopped, is performed for a predetermined period of time, is repeated a predetermined number of times according to the room humidity (Rh). Thus, the indoor unit's interior can be dried properly without occurrence of dew condensation therein.

Abstract: There is provided a method and apparatus for sanitizing sports equipment which comprises a cabinet which can be sealed, first and second conduits in fluid communication with the cabinet, an ozone generator, and fans for circulating ozone containing gas through the conduits into the cabinet, the fans being operative to circulate the ozone containing gas in a first direction and subsequently in a reverse direction. There is also provided a fluid storage device, the fluid storage device being associated with a spray action to spray the fluid into the cabinet after the ozone has been circulated.

Abstract: A universal building unit comprising a plurality of members connected to each other by at least one adjustable plate. There is also at least one panel connected to the plurality of members. In this case, the plurality of members, the adjustable plate, and the panels all connect together to form a universal building unit that can be repeatedly constructed and combined with adjacent building units to form a building structure. These building units also contain a heating and cooling system for heating and cooling each unit within the structure. In addition, these units can be combined in any manner to create stairs, walls, doors, fixed and movable partitions, windows, roofs, or any other type of building component. These building units comprise a series of simple, easy to install fittings and steel profiles to create framing for any type of building.

Abstract: An air flow chamber for cooking or chilling using alternating horizontal air flow has an air heating or cooling apparatus and an air recirculating flow control mechanism for forcing heated or cooled air through an enclosure wherein said air is alternatingly directed horizontally through said enclosure in a first cycle in one horizontal direction and in a second cycle in the opposite direction.

Abstract: A drier with a curvalinear chamber having a heat transfer surface at one end and baffles at the other end. A fan is provided to circulate air within the chamber. In the process for drying, the product to be dried is positioned within the chamber and air circulated across the heat transfer surface, toward the baffle, past the product, and back to the heat transfer surface.

Abstract: In order to dry boards, the boards are guided on racks through a drier and brought into contact with drying air in two stages. In a stage A with a higher drying power, the drying air is supplied at a higher temperature and with an at least average humidity, and in the other stage B, it is supplied at an average temperature and with a low humidity. The waste heat of the outgoing air from stage A is used for preheating the drying air. This process should reduce the consumption of primary energy. For that purpose, a process is known that consists of also using the outgoing air condensation heat. This has the inconvenience, however, of requiring substantially more secondary energy, as important air mass flows are required to transfer heat because of the low condensation temperature. Primary energy should be reduced by using condensation heat without substantially increasing secondary energy requirements.

Abstract: A drying shed includes at least one drying chamber (2) for accommodating wood (3) to be dried in a known manner, and further includes a drying unit arranged in the drying chamber and comprising a heat-exchange battery (6) and fans (4). The invention is characterized in that respective fan wheels or impellers are intended to be driven by a hydraulic motor. The hydraulic motor may be a reversible motor.
