Abstract: The present invention relates to an air curtain comprising a longitudinally extending frame comprising a longitudinally extending air inlet opening; and a longitudinally extending air outlet. According to the invention there is a row of electrical fans between the longitudinally extending air outlet and the longitudinally extending air inlet opening for introducing air into the air curtain and expelling it through the longitudinally extending, downward facing air outlet for generating an air-curtain. The invention also relates to a vehicle provided with such an air curtain.

Abstract: An apparatus and method is provided for drying and/or scenting sports equipment and the like. A sports bag is designed such that it has two openings which are covered by a mesh fabric or a rigid plastic screen. One opening is used to receive a blower fan engaged onto the mounting at the opening. The other opening is used to allow air to escape. Wet and/or foul smelling sports equipment is placed into the sports bag. An air freshener is inserted into a pocket located in the blower fan housing, or near to the opening of the intake opening of the sports bag. The fan is turned on (with or without a timer). In a relatively short period of time the sports equipment is dry, with little effort required or foul odor released outside the sports bag.

Abstract: The present invention provides a temperature control system for an aircraft ventilation system that couples with existing aircraft upstream ventilation system architecture and downstream ventilation system architecture. The temperature control system includes an air duct arranged to receive a volume of ventilation air from the upstream ventilation system architecture and transfer the volume of air to the downstream ventilation system architecture. A heater is arranged to heat the ventilation air. A controller is arranged to control the heater responsive to a comparison of the actual temperature of the ventilation air to a desired range of temperatures. The controller maintains the actual ventilation air temperature within the predetermined range of temperatures such that formation of ice is minimized in the aircraft ventilation system. An exhaust shutoff valve between the air distribution system and the lavatory/galley ventilation system provides for ventilation in the event smoke is detected.

Abstract: This invention has an object of providing an air conditioner for a railway vehicle which can restrict a reduction in the introduced volume of outside air during a high-speed running of a vehicle and which can achieve lower noise. To achieve this object, the air conditioner for a railway vehicle includes an external cover 4 provided along the same surface as a vehicle surface, an air intake port 5 with a periphery provided on the external cover 4 and having a roundness in the cross-sectional configuration of an inside edge portion 12a of the intake port periphery, an air intake louver 11 disposed in the air intake port 5 to intersect a vehicle running direction, and an air exhaust port 3 for exhausting air that has been heat-exchanged, wherein an upper end surface 11a of the louver 11 is recessed from the surface of the exterior cover 4, and a cross-sectional configuration of the edge portion 11b of the upper end surface 11a has a roundness.

Abstract: A smoke diverter system is provided including an elongated ceiling housing, an elongated outlet slot formed along a length of a bottom face of the ceiling housing. An elongated inlet slot is formed along a length of one of a pair of side faces of the ceiling housing adjacent to the top face thereof. At least one elongated intake filter is mounted between the inlet slot and the outlet slot of the housing. A vacuum fan is secured within the interior space of the ceiling housing for suctioning air from the inlet slot and excreting the same from the outlet slot.
