Abstract: A system and method of removing pathogens and particulates in a breathable air supply includes supplying pressurized air from a portable pressurized air source, flowing the pressurized air through a filter media including capturing multiple pathogens and particulate contaminates from the pressurized air, outputting filtered, pressurized air and delivering the filtered, pressurized air to a mask.

Abstract: Disclosed herein are systems and methods for reducing the particulate matter content of an exhaust gas from a carbon black process.

Abstract: The present invention relates to an assembly of two structural parts of a wind turbine wherein the structural parts are to be connected in a flange-to-flange connection by a number of bolts and such that a flange of the first structural part and a flange of the second are centrally and rotationally aligned whereby a first borehole in the flange of the first structural part is matched and aligned with a corresponding first borehole in the flange of the second structural part. The structural parts may for example be a tower section or a foundation section. The assembly further comprises a first and a second rotational guide member releasably attached to each of the flanges of the structural parts.

Abstract: A CO2 refrigeration system includes a CO2 refrigeration subsystem that provides cooling for a refrigeration load using carbon dioxide (CO2) as a refrigerant. The CO2 refrigeration system further includes a direct CO2 heat exchange subsystem that uses the CO2 refrigerant from the CO2 refrigeration subsystem to provide heating or cooling for a building zone. The direct CO2 heat exchange subsystem includes a heat exchanger that exchanges heat directly between the CO2 refrigerant and an airflow provided to the building zone.

Abstract: An offshore wind turbine generator comprises a tower 1 and a platform 2. The tower 1 is provided with a side door 4 accessed from the platform 2 using a stairway 5 leading to an upper platform 6. The upper platform 6 is formed from the upper surface of a cabinet 7 which houses a diesel backup generator. Both the backup generator and the cabinet 7 are mounted to the tower 1 by bolts, such that the cabinet and backup generator are fully supported by the tower 1. A diesel fuel tank 12 is also mounted to the tower 1 by bolts. The fuel tank supplies diesel fuel to the backup generator.

Abstract: A power pack [2] is located within a housing [3] on the platform [1] of a wind turbine generator tower. The power pack [2] is supplied from a fuel tank [4]. With the door [6] of the housing [3] open, the power pack [2] may be removed for servicing and repair by using a U-shaped support structure [8] to which an electric motor [11] is mounted. Two support rails [12] permanently located within the housing [3] support the housed power pack [2]. A chain [15] attached to the power pack [2] is driven by the motor [11] to remove the power pack [2] from the housing [3] by sliding the power pack [2]along the support structure [8]. A pulley arrangement reduces the necessary torque. After removing the power pack [2] from the housing [3], a crane [7] is used to lift the power pack [2] from the platform [1] and to lower it down to a sea vessel [17].

Abstract: A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

Abstract: A C02 refrigeration system has an LT system with LT compressors and LT evaporators, and an MT system with MT compressors and MT evaporators, operating in a refrigeration mode and a defrost mode using C02 hot gas discharge from the MT and/or the LT compressors to defrost the LT evaporators. A C02 refrigerant circuit directs C02 refrigerant through the system and has an LT compressor discharge line with a hot gas discharge valve, a C02 hot gas defrost supply header directing C02 hot gas discharge from the LT and/or the MT compressors to the LT evaporators, a flash tank supplying C02 refrigerant to the MT and LT evaporators during the refrigeration mode, and receiving the C02 hot gas discharge from the LT evaporators during the defrost mode, and a control system directing the C02 hot gas discharge through the LT evaporators and to the flash tank during the defrost mode.

Abstract: A kinetic energy capture device consisting of one or more wings having a high coefficient of lift and which leading edge of the wing or wings faces substantially in the direction of the wind or gas passing around the wing. The wing is designed to have a very high coefficient of lift in a low Reynolds gas or wind flow. The wing or wings are connected to a rotationally structure, which contains an axle. The axle of the kinetic energy capture device has an orientation substantially horizontal relative to the ground. The kinetic energy capture system is designed to minimize costs, minimize environmental impact, maximize reliability and optimize the production of electrical energy in a kinetic environment where the average Reynolds number is low.
