Patent DE-3916737-A1 (DE)
Title: Engineering arrangement for the biodegradation of chlorinated organic solvents
Inventor: FRAHNE DIETRICH DR RER NAT
IPC: C02F3/00
Filed: 1989-05-23
Abstract: The process relates to the disposal of waters polluted with chlorinated hydrocarbon-based solvents, so-called contact waters. In the first process stage, the solvents are removed from the contaminated water by a stripping process and thus separated off from other non-volatile accompanying substances possibly interfering with the biodegradation. In the second process stage, the expelled solvents are added to the gas-introduction stream of a biologically active fixed-bed filter, to which gas is introduced from below and which is adapted to the biodegradation of chlorinated hydrocarbons. As a result of the adsorption characteristics of the fixed bed, the chlorinated hydrocarbons are removed from the gas stream and made available for biodegradation. The biodegradation itself proceeds as cometabolism with addition of a nutrient solution containing an easily utilisable carbon source and with an oxygen minimization and leads to mineralisation of the organically bound chlorine to form chloride. <IMAGE>

Patent DE-4016611-A1 (DE)
IPC: B60R21/00
Filed: 1990-05-23
Abstract: The invention relates to a safety device in a motor vehicle with side windows of toughened laminated safety glass with an inserted intermediate plastic film (8). According to the invention, the motor vehicle is fitted with means for absorbing a side-on collision and a striker device (5) which is activated in a side-on collision and is tensioned to provide a definite strike resulting in breakage of the side window (4). Thus the side window is caused to break after a side-on collision before it is struck by the head of a passenger and, as it has an intermediate plastic film (8), becomes yielding, thus reducing the risk of injury. In embodiments of the invention the striker device may be actuated mechanically or by a pyrotechnic charge. The proposed means for detecting a side-on collision is an elongated, fluid-filled sensor chamber in the side region of the vehicle which is depressed in the event of a side-on collision and the fluid is compressed out of the sensor chamber. This pressure rise is used either to make an electric switching contact or to actuate the striker device directly.
