Publication number: 20040189284Abstract: An actuator element suitable, for example, for actuating a rotatable disk or a flap valve shaft. The actuator includes a housing, a drive situated in the housing, and at least one position detector, in which a movably mounted piston rod in the housing is operatively connected to the drive for exerting a force effect, and in which the position detector includes at least one stationary Hall sensor and at least one magnet movable relative to the Hall sensor such that the magnet produces a magnetic field for generating a magnetic flux.Type: ApplicationFiled: February 4, 2004Publication date: September 30, 2004Applicant: Mann & Hummel GmbHInventors: Thomas Haubold, Dirk Traichel

Patent number: 6764771Abstract: The invention relates to a product (1), particularly a gas turbine blade that can be exposed to a hot aggressive gas (7). The product (1) has a metallic basic body (2), which is provided with a thermal barrier coating (4) having a spinel of the composition AB2O4.Type: GrantFiled: December 22, 2000Date of Patent: July 20, 2004Assignee: Siemens AktiengesellschaftInventors: Beate Heimberg, Wolfram Beele, Karl Kempter, Ulrich Bast, Thomas Haubold, Michael Hoffmann, Axel Endriss, Peter Greil, Chu-Wan Hong, Fritz Aldinger, Hans J.

Patent number: 6705272Abstract: An air intake system for intake air of an internal combustion engine comprising a filter insert (19) in a housing (10) connected to the air conducting system by a plurality of inlets (13) and an outlet (22). The air inlets are provided with individual intake nozzles or fittings and lead to a single common air chamber (20) in the filter housing. The inlets (13) can be individually opened and closed by flap valves (24), thereby allowing the acoustics to be influenced favorably and enabling, for example, the respective intake fittings to be connected or disconnected depending on the temperature. The intake system requires only a limited number of components, and the design of the preferably wedge-shaped air chamber minimizes flow losses in the housing, which in turn decreases the intake noise. Shunt resonators (28) can also be formed using cover elements (29) and (30).Type: GrantFiled: April 24, 2002Date of Patent: March 16, 2004Assignee: Filterwerk Mann & Hummel GmbHInventors: Rudolf Leipelt, Rolf Fuesser, Robert Vaculik, Thomas Haubold

Patent number: 6602553Abstract: An article that is particularly well suited for use as a gas turbine engine component has a metallic substrate and a ceramic thermal barrier layer including a mixed metal oxide system comprising a compound selected from the group consisting of (i) a lanthanum aluminate and (ii) a calcium zirconate, the calcium in which is partially replaced by at least one calcium-substitute element, such as strontium (Sr) or barium (Ba). In addition, the lanthanum in the lanthanum aluminate can be partially replaced by a lanthanum-substitute element from the lanthanide group, particularly gadolinium (Gd). A process for producing such an article comprises providing a pre-reacted mixed metal oxide system as described above and applying it to the substrate by plasma spraying or an evaporation coating process.Type: GrantFiled: July 1, 2002Date of Patent: August 5, 2003Assignees: Siemens Aktiengesellshaft, Rolls-Royce Deutschland GmbHInventors: Beate Heimberg, Wolfram Beele, Karl Kempter, Ulrich Bast, Thomas Haubold, Michael Hoffmann, Axel Endriss, Peter Greil, Chu-Wan Hong, Fritz Aldinger, Hans J.

Patent number: 6564768Abstract: An intake system for an internal combustion engine of a motor vehicle, which includes a first air intake 10, which is arranged at a point in the motor vehicle that is advantageous for air intake, and a second air intake 11, which is arranged at a point that is protected from road spray and splashes of water. The two air intakes 10, 11 end in a common line 12 that communicates with the internal combustion engine. In the first air intake 10, a moisture sensor 14 is arranged. When water enters into the first air intake 10, this moisture sensor emits a signal that actuates a solenoid 23 to move a pivotable valve 13. In a first switching position pivotable valve 13 closes the second air intake 11 so that no air reaches line 12 from the second air intake 11. In a second position (shown in broken lines) pivotable valve 13 closes the first air intake 10 so that air reaches line 12 only through the second air intake 11.Type: GrantFiled: October 26, 2001Date of Patent: May 20, 2003Assignee: Filterwerk Mann & Hummel GmbHInventors: Sascha Bauer, Thomas Haubold, Michael Kolmeder

Patent number: 6453866Abstract: An intake system for an internal combustion engine of a motor vehicle which includes a first unfiltered air intake (10) which is arranged at a location in the vehicle that is favorable for air intake, and a second unfiltered air intake (11) which is arranged at a location in the vehicle that is protected against road spray and splashes of water. The two unfiltered air intakes (10, 11) each open into a common line (12) which communicates with the internal combustion engine. In the first unfiltered air intake (10) there is a moisture sensor (14) which emits a signal when water enters the first unfiltered air intake (10). This signal actuates a drive member 23 which moves a flap 13 between first and second switching positions. In the first switching position, the flap 13 closes the second unfiltered air intake 11, so that no air can get into line 12 from the second unfiltered air intake 11.Type: GrantFiled: October 26, 2001Date of Patent: September 24, 2002Assignee: Filterwerk Mann & Hummel GmbHInventors: Klaus Altmann, Andreas Epp, Thomas Haubold, Klaus Lieb, Jochen Linhart, Hermann Maurer, Juergen Werner
