Publication number: 20110226979Abstract: A flush valve has a valve body having an inlet and an outlet. A piston is disposed in the valve body between the inlet and the outlet. A piston cap is disposed within the valve body and has a wall along which the piston is guided. A groove is disposed in the piston cap wall for equalizing pressure on sides of the piston translating therein. The groove has a shallow, semicircular shape whereby a possibility that fluid flow therethrough is diminished is minimized.Type: ApplicationFiled: March 3, 2011Publication date: September 22, 2011Inventors: Frank A.

Publication number: 20100269248Abstract: A flush valve utilizes a sensor to determine how close a user is to a toilet to determine whether to utilize a longer flush with more water to remove, typically, solid waste or a shorter flush with less water to remove, typically, liquid waste. If a user is in a zone that is closer to the toilet, a longer flush is deemed necessary and if a user is in a zone farther from the toilet, a shorter flush is deemed necessary. Users sometimes move between one zone or the other and the flush valve determines whether a user spends more or less time in the zones to determine whether to provide a shorter or a longer flush.Type: ApplicationFiled: April 28, 2009Publication date: October 28, 2010Inventors: Bart Nowak, Xan Vy Du, Frank A. Stauder, Jeff Belz

Publication number: 20090320199Abstract: A spray system, which reduces contamination caused by toilet flushing, is activated during a flush cycle to contain waste matter and prevent escape thereof from the bowl. The system is mounted above the level of water in a toilet and includes an aperture that creates a spray and is fluid communication with the flush valve of the toilet. Accordingly, each time the flush valve is activated, a portion of the water provided to the toilet is directed to the aperture to create a spray to minimize escaping effluent.Type: ApplicationFiled: May 6, 2009Publication date: December 31, 2009Inventor: Frank A.

Patent number: 6832644Abstract: An engine cooling module 10 which includes a shroud 12, a heat exchanger 18, a fan 14, a motor 13 for driving fan 14, and a plurality of air dams 1. Shroud 12, circumscribing the fan, has a main opening to allow air to pass through the fan to or from a heat exchanger 18. Fan 14 is associated with the shroud 12 to be adjacent to the fan opening to permit air moved by the fan to pass through the heat exchanger. Air dams 1 allow air to flow more easily in one direction than the opposite direction. In the fan flow direction, air dams 1 provide relatively little resistance to the flow. In the direction opposite to fan flow direction, air dams 1 provide more resistance than as compared to the resistance when air flows in the fan flow direction. Under ram air conditions (e.g., when the vehicle is moving), the use of air dams can reduce the load on the fan's motor by cooling properties of ram air, while reducing recirculation, thereby increasing efficiency.Type: GrantFiled: September 20, 2001Date of Patent: December 21, 2004Assignee: Siemens VDO Automotive Inc.Inventors: Frank A. Stauder, Alexander Graham Hunt

Patent number: 6611071Abstract: A cooling assembly includes an electric motor 10 for driving a fan 16. At least one spoke structure 18 is coupled to and extends generally radially from a periphery of the motor body so as to be exposed to airflow caused by rotation of the fan 16. An electronic component 24 of the motor is operatively associated with the spoke structure 18 such that heat of the electronic component is conducted to the spoke structure and to a spoke extension 22.Type: GrantFiled: August 17, 2001Date of Patent: August 26, 2003Assignee: Siemens Automotive Inc.Inventors: Frank A. Stauder, David J. Naish

Patent number: 6532909Abstract: An engine cooling module 10 includes a shroud 12 having at least one fan opening 15 and at least one additional opening 18 in the wall generally adjacent to the fan opening to permit air to pass though the shroud 12. A fan 14 is coupled to the shroud to permit air moved by the fan to pass through the shroud 12. An electric motor drives the fan. Closure structure 20 is movable to prevent and permit air flow through the additional opening 18. An actuator 28 moves the closure structure 20 from a closed position, covering the additional opening 18, to an opened position, uncovering the additional opening 18. A sensor 34 detects ram air at the shroud 12. A controller 32 receives a signal from the sensor 34 indicating the initial presence of ram air and, in response thereto, sends a signal to the actuator 28 to move the closure structure 20 to the opened position.Type: GrantFiled: March 20, 2001Date of Patent: March 18, 2003Assignee: Siemens Automotive Inc.Inventors: Frank Stauder, John Makaran, Andrew Lakerdas

Patent number: 6471472Abstract: A turbomachine for moving air comprising includes a shroud disposed about a longitudinal axis and a rotor assembly mounted for rotation about the longitudinal axis. The rotor assembly has a plurality of blades and tips of the blades are coupled to an annular band. The annular band is disposed with respect to the shroud so as to define a gap extending continuously between an outer surface of the annular band and an inner surface of the shroud. A seal structure extends from the inner surface of the shroud and into the gap. The seal structure has a density sufficient to reduce swirl in recirculating airflow and to minimize air leakage across the gap.Type: GrantFiled: August 25, 2000Date of Patent: October 29, 2002Assignee: Siemens Canada LimitedInventors: Frank Stauder, Ian Lockley, Sylvain Nadeau, William Holmes, Alexander Graham Hunt
