Inventor: SCHNAIBEL EBERHARD
IPC: F01N3/08
Filed: 2001-07-11
Abstract: L'invention concerne un procédé de fonctionnement d'un catalyseur accumulateur d'oxydes d'azote (NOx) (12') situé dans un moteur à combustion interne (1), en particulier un véhicule automobile. Selon ce procédé, des oxydes d'azote sont accumulés dans le catalyseur accumulateur (12') au cours d'une première phase de fonctionnement du catalyseur accumulateur (12') ; les oxydes d'azote accumulés sont retirés du catalyseur accumulateur (12') pendant une seconde phase de fonctionnement et la quantité d'oxydes azote accumulée est déterminée dans la première phase de fonctionnement. Afin de pouvoir définir le plus précisément possible le début et la fin de la seconde phase de fonctionnement, une grandeur caractérisant la quantité d'oxydes d'azote retirée est déterminée dans une seconde phase de fonctionnement et comparée à la quantité d'oxydes d'azotes accumulée déterminée dans la première phase de fonctionnement. Pendant la comparaison, un test de plausibilité et un équilibrage du signal de sortie d'un détecteur de Nox (14') monté en aval du catalyseur accumulateur (12') peuvent être effectués.

Title: Air classification of minerals using preheated and - moisture enriched air
Inventor: KAISER FRITZ
IPC: B07B11/02
Filed: 1968-10-19
Abstract: Improved performance of air classifiers for separating mineral powders is obtained by pre-heating and increasing the moisture content of the air employed for the classifying action. The tendency for powdery materials to agglomerate is reduced thereby giving improved results, partic. for fine powders of CaCO3-contg. materials such as limestone and chalk etc. Optimum results are obtained with and chalk etc. Optimum results are obtained with the air at 115 degrees C having a dew point of 80 degrees C. Air used in a drying plant can be utilised thus improving economy.

Patent DE-1966067-A1 (DE)
Title: Non-cutting processing of toothed gears by - rolling-off on gear or rack-shaped tools
Inventor: HURTH FRITZ
IPC: B21H5/02
Filed: 1969-04-16
Abstract: The workpiece makes a longitudinal advance relative to the tool, the direction of the movement being on a plane parallel to the tangent plane, which passes through the contact point of the two rolling cycles of tool and work piece. The smallest distance between the two axis is of such a size, that a pressure component originates, which is radial to them. Due to this a relatively small force is necessary for the advance drive, the radial force being absorbed by supporting elements for tool and work piece. The work piece is worked to an exact pre-determined measurement, with the surface of the tooth profiles being of high quality. The tool itself has a very long life time.

Title: Gas turbine for motor vehicle - has complisor combustion chamber heat exchanger and air branch pipe facilitating pre-heating
Inventor: FIALA ERNST PROF DR
IPC: F02C7/12
Filed: 1973-06-14
Abstract: Two separate airstreams are supplied from the compressor. One by passes combustion chamber completely and expands straight into turbine and into atm. The other air stream goes through the combustion-chamber, is intensely heated and is fed to the turbine after which it then passes through the heat exchanger into atm. This results in considerable reduction in size of heat-exchanger which renders it more suitable for mobile use. The branch piece in which the two air streams separate may be in front or inside the heat exchanger to promote pre-heating.

Title: Magnetically variable resistor with temperature compensation - has magnetic shunt with temperature dependent permeability
Inventor: SCHWENK HANS-MARTIN
IPC: H01C7/02
Filed: 1973-07-25
Abstract: The magnetically variable resistor between the poles of the magnet has its value controlled by the position of the element, whose relative permeability is greater than unity, in relation to the magnet poles. The temperature dependence of the magnetically variable resistor is compensated for by inserting a magnetic shunt across the magnet limbs which is made of a material whose permeability varies with temperature in the appropriate direction. Thus for changing temperature the flux crossing between the poles can be made sensibly constant over a wide range. The air gap may be omitted if necessary.
