Patent number: 6739179Abstract: A measuring device for determining the oxygen content in gases is described. The measuring device is disposed between two magnets that are positioned at a distance from one another. The measuring device is equipped with a sensor that is held rotatably within a frame. The sensor has two parallelepipedic bodies that are both made hollow or solid and are connected to one another via a web-shaped structural element. The web-shaped structural element is fastened to the frame via at least one holding element, so that the sensor can be rotated about its center of gravity. The amount of rotation is dependent on the quantity of oxygen that is concentrated between the two magnets. A current can be conducted through a conductor track led on the surface of the sensor and generates a correspondingly high restoring force by which the sensor is brought into the position of rest again.Type: GrantFiled: October 29, 2001Date of Patent: May 25, 2004Assignee: ABB Patent GmbHInventors: Albrecht Vogel, Dieter Binz, Manfred Wetzko, Peter Krippner

Patent number: 6651509Abstract: There is disclosed a measurement mechanism for differential pressure measurement. The mechanism has two housing portions with flanges. A differential pressure sensor is force-fit between the two flange faces. An electronics board is connected to the differential pressure sensor by means of a force-fit electrical contact.Type: GrantFiled: June 14, 2002Date of Patent: November 25, 2003Assignee: ABB Patent GmbHInventors: Wolfgang Scholz, Albrecht Vogel, Peter Krippner, Manfred Wetzko

Patent number: 6640640Abstract: A differential pressure sensor has a first and a second measuring chamber. Each measuring chamber is limited by a rigid carrier plate and a diaphragm plate, which is formed in the region of the measuring chamber as a pressure-sensitive measuring diaphragm. To design the differential pressure sensor to be resistant to overloading, the carrier plate is arranged between a first and a second diaphragm plate and has congruent concave depressions on opposite sides in the plane of the plate. The depressions are connected to one another by a central duct, penetrating the carrier plate perpendicularly to the plane of the plates. In the region of the measuring chambers, the diaphragm plates are formed congruently in relation to the depressions as pressure-sensitive measuring diaphragms. The measuring chambers are coupled to one another by a ram guided axially movably in the duct.Type: GrantFiled: June 14, 2002Date of Patent: November 4, 2003Assignee: ABB Patent GmbHInventors: Wolfgang Scholz, Albrecht Vogel, Peter Krippner

Patent number: 6598482Abstract: A differential pressure sensor has a first and a second measuring chamber.

To design the differential pressure sensor to be resistant to overloading, the carrier plate is arranged between a first and a second diaphragm plate and has congruent concave depressions on opposite sides in the plane of the plate. The depressions are connected to one another by a decentered duct, penetrating the carrier plate perpendicularly to the plane of the plates. In the region of the measuring chambers, the diaphragm plates are formed congruently in relation to the depressions as pressure-sensitive measuring diaphragms. The measuring chambers and the duct are filled with an incompressible fluid.Type: GrantFiled: June 14, 2002Date of Patent: July 29, 2003Assignee: ABB Patent GmbHInventors: Wolfgang Scholz, Albrecht Vogel, Peter Krippner

Patent number: 6568275Abstract: There is described a capacitive differential pressure sensor made using glass-silicon technology with a diaphragm plate of silicon, which is arranged between two carrier plates consisting of glass. The diaphragm plate has pressure-sensitively deflectable regions, which are respectively provided with a capacitor arrangement. The capacitor arrangement is connected to a measured-value processing device through connecting conductors. To improve the ratio of the measuring capacitances to the parasitic capacitances brought about by the connecting conductors, the diaphragm plate is outside the pressure-sensitively deflectable region the substrate of an electronic circuit which comprises at least one input stage of the measured-value processing device.Type: GrantFiled: June 14, 2002Date of Patent: May 27, 2003Assignee: ABB Patent GmbHInventors: Wolfgang Scholz, Albrecht Vogel, Peter Krippner, Dieter Binz

Patent number: 6564155Abstract: A method and an apparatus tests liquids. When the method is implemented, following a reaction of constituents in the liquid with the maximum quantity at least of one free oxidizing agent and/or reagent contained in the liquid, the quantity of oxidizing agent and/or reagent remaining in the liquid is displayed visually as a measure of the quantity of constituents in the liquid reacting with the oxidizing agent and/or reagent. For implementing the method, use is made of a sensor that is configured as a sheet-like structural element and is provided with at least one inlet opening, a sample-accommodating channel, a mechanical pump, a transporting capillary, a detection zone, an emptying channel, and an outlet opening.Type: GrantFiled: July 23, 2001Date of Patent: May 13, 2003Assignee: ABB Patent GmbHInventors: Albrecht Vogel, Dieter Binz, Peter Krippner, Sean Keeping

Publication number: 20030065236Abstract: The invention relates to a process and an apparatus for the low-corrosion and low-emission co-incineration of highly halogenated wastes, in particular liquid waste, in waste incineration plants having at least one combustion chamber, a waste-heat boiler, a multistage flue gas scrubber comprising a single-stage or multistage acidic scrubber and an alkaline scrubber, in which sulfur or a corresponding sulfur carrier is added under control to the primary and/or secondary combustion chamber. The amount of sulfur is controlled substantially in proportion to the current halogen loading originating from the waste in the boiler flue gas.Type: ApplicationFiled: June 26, 2002Publication date: April 3, 2003Inventors: Bernhard Vosteen, Joachim Beyer, Peter Krippner

Patent number: 6536288Abstract: There is described a differential pressure sensor made using glass-silicon technology with a diaphragm plate arranged between two carrier plates. To achieve a high resolution at the beginning of the measuring range in conjunction with high overload resistance, the measuring diaphragm plate of the sensor has for a prescribed measuring range within the same measuring chambers a plurality of mutually independent deflectable regions as measuring diaphragms. Each such region acts as a part-sensor with a part-measuring range. The part-measuring ranges of the part-sensors overlap and in total are equal to the prescribed measuring range of the differential pressure sensor. The displacement of the measuring diaphragm of each part-sensor is mechanically limited outside its part-measuring range by the carrier plates.Type: GrantFiled: June 14, 2002Date of Patent: March 25, 2003Assignee: ABB Patent GmbHInventors: Wolfgang Scholz, Albrecht Vogel, Peter Krippner, Dieter Binz

Patent number: 6523362Abstract: A support element is described which can combine components used in Microsystems technology to form a single unit. Because of the very small dimensions of the support element, it is difficult to keep the components at different temperatures if this is required for them to operate. With the support element, this difficulty is avoided by the fact that at least one thermal insulation device, which shields the plate and the cover of the support element with respect to internal and external environments in certain regions, is provided.Type: GrantFiled: January 10, 2002Date of Patent: February 25, 2003Assignee: ABB Research LtdInventors: Dieter Binz, Albrecht Vogel, Peter Krippner
