Title: Method of removing soot particles from diesel exhaust - has perforated pipe inserted in front of converter
Inventor: JESSER RAINER
IPC: F01N3/037
Filed: 1991-07-03
Abstract: A diesel engine with an oxidation-type catalytic converter (4) in the exhaust pipe (1) has a perforated pipe (9) located immediately upstream of the converter.

Title: Measuring and monitored neutralising of surface charges on objects, e.g. paper or plastic foil - using charge neutralising brush whose position is varied according to measured charge
Inventor: DOMES HELMUT DR
IPC: G01R29/24
Filed: 1992-07-25
Abstract: The method involves using a charge neutralising brush (5) of thin electrically conducting wires.  The quantity of charge on the object (1) surface  is measured with a charge sensor (2). The discharge current flowing via the neutralising brush is measured and both measurement parameters fed into a microprocessor (11)  which determines the already compensated charge and the residual charge. The charges are compared to produce a control signal which is used to control the distance of the brush from the surface of the object by means of an electromechanical positioning mechanism (7).  Complete compensation of the charge is achieved during the transition time of the object. USE/ADVANTAGE - E.g. for measuring and neutralising charge on surface of paper or plastic foil. Method enables definite discharge to be caused independent of charge state, material properties and thickness of object.

Title: Process for scrubbing acidic gas components out of flue gases by absorption
Inventor: LEDERER THOMAS DR
IPC: B01D53/14
Filed: 1993-02-12
Abstract: The invention relates to a process for scrubbing acidic gas components out of flue gases, in particular from waste gases of refuse incinerators and hazardous waste incinerators by absorption for the purpose of recovering crude acids. It is the object of the invention to design the isolation of the acidic gas components of the waste gases in such a way that re-usable crude acids can be recovered therefrom by simple means in an inexpensive and energy-efficient manner. According to the invention, the object is achieved when the temperature is lowered in at least one cleaning stage below the limiting cooling temperature of the flue gases by means of a cooling device, a part of the cooling water evaporated in the quenching stage being condensed out on the surface of the cooling body as a liquid film running off, and the acidic gas constituents being scrubbed by the water, which has been condensed out, out of the flue gases by intensive turbulence, and the laden scrubbing liquid is removed from the process when the desired concentration of crude acid has been reached. <IMAGE>

Title: Method and device for rescuing those in distress at sea who have fallen overboard
Inventor: HARTEL RALF
IPC: G08B7/00
Filed: 1993-03-04
Abstract: Known methods for finding those who have fallen overboard are virtually always based on optical perception and presuppose sufficiently good visibility conditions. A similar statement holds for known radio alarm transmitters, since they are not suitable for reliable direction finding. The novel method is intended to enable the victim to be found reliably and simply under all weather conditions. After a person has fallen overboard, a very compact underwater sound transmitter (1) permanently worn on the body automatically emits signals. Immediately after they have been received by onboard underwater microphones (3) a marker buoy (2) which is provided with an underwater sound transmitter (4) of substantially greater range is set afloat. The ship (boat) is equipped with a corresponding direction finder. The method and the device permit the safety of people on the water to be increased in professional and sports sailing. <IMAGE>
