摘要:
The invention relates to a process for the electrolytic dissociation of hydrogen sulfide dissolved in an amine scrubber solution in an electrolysis cell (11) which has an anode space (9) and a cathode space (15), with the anode space (9) and the cathode space (15) being separated by a membrane (13), in which at least one supporting electrolyte is added to the amine scrubber solution, an anion-conducting membrane is used for separating anode space (9) and cathode space (15) and/or the amine scrubber solution in which the hydrogen sulfide is dissolved comprises at least 10% by volume of potassium N,N-dimethylaminoacetate. The invention further relates to a use of the process.
摘要:
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 base don 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.

摘要:
A data carrier printed by line intaglio having a halftone image represented by irregular line structures in the manner of an engraving. The line structures are superimposed at least partly by fine structures rendered in positive or negative representation. Methods are provided for generating and processing irregular line structures as digital image data on a computer following individual specifications by an operator. The line structures are transferred to a line intaglio printing plate. The digital image data is used for controlling an engraving apparatus. In the alternative, other printing processes may be involved wherein the digital image data is superimposed at least partly with fine structures rendered in positive or negative representation.
摘要:
In a method for emergency ventilation of an aircraft cabin, a leak is detected in the area of an air mixer of an aircraft air conditioning system. An emergency air flap, which in a closed position prevents an air exchange between an aircraft area adjacent to the air mixer and the aircraft cabin, is controlled into an open position. Air from the aircraft area adjacent to the air mixer is conveyed through the open emergency air flap into the aircraft cabin.
