Abstract: In a method for emergency ventilation of an aircraft cabin (12) a leak is detected in the area of an air mixer (24) of an aircraft air conditioning system (16). An emergency air flap (38), which in a closed position prevents an air exchange between an aircraft area (40) adjacent to the air mixer (24) and the aircraft cabin (12), is controlled into an open position. Finally, air from the aircraft area (40) adjacent to the air mixer (24) is conveyed through the open emergency air flap (38) into the aircraft cabin (12).

Abstract: Nowadays in aircraft on-board inert gas generation systems (OBIGGS) are used to generate inert gases. Cooled bleed air of engines or auxiliary turbines is fed to said OBIGGS systems. According to an embodiment of the present invention, an air supply device for an OBIGGS system in an aircraft is proposed that comprises a bleed position (1,2). By way of the bleed position (1,2), air from an air conditioning unit (4,5) on board the aircraft can be bled and can be fed to the OBIGGS system. There is thus no need for an additional heat exchanger and an additional ram-air channel. Maintenance expenditure and air resistance are thus reduced.

Abstract: The invention relates to an air guiding flap of an aircraft wherein one surface thereof faces an air duct and is exposed to a prevailing pressure in the air duct and whose opposite surface is exposed to the pressure of the relative wind flowing past the aircraft. The air guiding flap comprises an actuator for automatically opening and closing the air guiding flap which actuator cooperates with a device for controlling the position of the air guiding flap. In order to keep the stress on the air guiding flap low a force detecting device is provided which detects the force impinging on the actuator based on a difference between the prevailing pressure in the air duct and the pressure of the relative wind flowing past the aircraft. The controlling device adjusts the position of the air guiding flap such that the force impinging on the actuator at any one time is at least essentially zero.

Abstract: A method and apparatus for heat treating waste materials including pyrolysing the waste materials in a first heating zone to produce pyrolysis gas containing dust and impurities, removing at least 90% of the dust from the pyrolysis gas, and burning the pyrolysis gas to produce flue gas. The flue gas produced is either immediately denitrogenated non-catalytically or first cooled and then catalytically denitrogenated. Following denitrogenation the flue gas is filtered to purify the gas.

Abstract: A method for thawing frozen road culverts. The first step involves positioning an electrically conductive cable in a road culvert prior to an ice blockage occurring. A connection end of the electrically conductive cable is anchored in an accessible location. The second step involves connecting a power source to the connection end of the electrically conductive cable after an ice blockage of the road culvert has occurred and supplying power to the electrically conductive cable, such that energy generated by power flowing through the electrically conductive cable causes a flow path to be created through the ice blockage in the road culvert.
