Abstract: A louver assembly includes a heating element configured to provide heat to at least one edge of at least one blade of the louver assembly to prevent or eliminate ice build-up along the edge of the blade. Variations include fixed blades, rotatable blades, power supply lines routed through pivot points or mechanical linkages for moving blades, and different forms of heating elements such as wires that produce heat due to electrical resistance or infrared heating panels.

Abstract: A system for cooling a battery mounted on a vehicle using air within a vehicle, independently of the travelling state of the vehicle. The air within a vehicle compartment is guided to a battery mounted on a vehicle to cool the battery. A controller determines a basic fan speed v of the cooling fan based on a battery temperature and an ambient temperature. Further, the controller calculates an increment ?v of the fan speed in accordance with the vehicle speed and the degree of window opening and determines a final fan speed V according to V=v+?v, to drive the cooling fan. By controlling the fan speed to increase, it is possible to cool the battery even when the base pressure of the inlet-side static pressure of the cooling fan becomes negative pressure compared to when the windows are closed.

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: A device for delivering conditioned air into a passenger area of a rail vehicle, said device comprising a duct extending along the bottom of a side wall of the passenger area, that side face of said duct which is adjacent to the inside of the passenger area being provided with air outlet means disposed over the entire length of the duct and designed so as to release a flow of air across the floor of the vehicle, the top of the duct being provided with openings opening out in a space defined laterally by two substantially parallel walls adjacent to the side wall of the vehicle, said space opening out via its top into the passenger area and its wall that is adjacent to the inside of the passenger area being provided, close to the duct, with one or more slots into which air contained in the passenger area is sucked, wherein said openings are distributed over the length of the duct such that air outlet zones provided with openings are disposed in alternation with barrier zones not provided with any openings, and

Abstract: A truck with a heating/cooling climate control system that is effectively integrated into a trailer or straight truck body, even as an after-market/field installation, which provides a uniform temperature distribution throughout the truck. An air flow which is sufficient to maintain the proper temperature environment throughout the entire beverage storage areas of the trailer or straight truck body is achieved without ducting of the supply air flow.

Abstract: A sanitary system for a locomotive wherein the treatment tank is protected from freezing by the use of the heat available in the exhaust air removed from the toilet compartment. A sealed and insulated compartment is formed around the treatment tank, and a vent is connected between the toilet room and the insulated compartment. A suction line located at an opposed position in the insulated compartment is used to direct the flow of air from the toilet room, through the insulated compartment around the treatment tank, to the locomotive exterior. By eliminating the need for heat tracing of the treatment tank, this invention reduces the cost and energy usage of the locomotive sanitary system.

Abstract: An apparatus for preventing sudden changes of pressure in an air conditioned or ventilated vehicle, the vehicle comprising: an inlet orifice (3) for outside air and an outlet orifice (5) for inside air, the inlet orifice being connected to an intake duct (2) directing the air taken in to an air conditioning or ventilation system, the outlet orifice being connected to an exhaust duct (4) exhausting the inside air to the outside; shutter means (6, 7) for the intake and exhaust ducts (2, 4); a control member (14) receiving signals from the detector; and detector means (16, 17) for detecting the pressure outside the vehicle Po and the pressure inside the vehicle Pi and delivering signals representative of the pressure wave.

Abstract: A method of and a device for magnetic-abrasive machining of parts has an external magnetic field providing a magnetic flux, a supply of a magnetic-abrasive powder to the part in the magnetic field. The part is rotated and oscillated about the longitudinal axis so that magnetic-abrasive powder is displaced by the rotating part in a circumferential direction. A fluid jet is directed toward the magnetic-abrasive powder so as to press the magnetic-abrasive powder against a surface of the part. The fluid jet is to improve the material removal rate of machining.

Abstract: The invention relates to a device for eliminating sudden changes of pressure in a ventilated or air-conditioned vehicle, the device comprising: a detector for detecting changes in the pressure outside the vehicle and delivering signals representative of said changes; closure means for closing an outside air suction duct and an inside air rejection duct; a control unit receiving the signals from the detector and controlling closure of the ducts above a first determined rate of change in outside pressure, said unit also controlling re-opening of the ducts after said change in outside pressure has fallen below a second determined rate; and means for balancing the inside pressure and the outside pressure by a controlled flow of air between the outside and the inside of the vehicle, said means constraining the pressure inside the vehicle to change as a function of time at less than a set rate.
