Patent number: 10190679Abstract: A method for determining a conveying capacity of a hydraulic pump includes opening a blockable flow cross-section in order to connect a pressure side of the hydraulic pump to an area of the hydraulic system through the flow cross-section after operating the hydraulic pump driven at a defined rotational speed. The flow cross-section is configured with the hydraulic pump such that an entire conveying volume flow provided by the hydraulic pump is guided through the flow cross-section when the flow cross-section is open. The method further includes comparing a change to an operating state of the transmission resulting from opening of the flow cross-section to a reference change to the operating state and determining the conveying capacity of the hydraulic pump as a function of a deviation between the change to the operating state and the reference change to the operating state.Type: GrantFiled: February 17, 2017Date of Patent: January 29, 2019Assignee: ZF FRIEDRICHSHAFEN AGInventors: Markus Terwart, Rainer Novak

Publication number: 20100275779Abstract: A split type potable water extractor from ambient air and water dispenser is invented, comprising separate water generating block located outside a water use area and water dispensing block located inside a water use area. The water generator block cycles refrigerant through a condenser and an evaporator to create condensation by heat exchange with ambient air circulated by an intake airflow system. The condensate water is collected and purified in a cascade of bactericidal loop to remove impurities. The purified water is pumped to a dispensing apparatus which can be installed in the home or other area of water use separate from the water generating block. If any one of the functional parts or units of water generator is disabled the water generator immediately stops operating to deliver water to the tank of the dispensing apparatus.Type: ApplicationFiled: April 30, 2009Publication date: November 4, 2010Inventor: Zohrab Melikyan

Patent number: 7806951Abstract: The present invention is a mobile air contaminant control system that includes a filter assembly enclosed by a mobile outer chamber. The filter assembly is tapered to create a large volume air way downstream from the filter assembly that enables more even air flow and filter loading. One or more exhaust fans pull the air through the filter assembly and exhaust it to the exterior of the chamber. The system is functionally attached to an exterior structure having at least one air intake and housing a work piece. As airborne contaminants are generated from the work piece(s), the control system exhausts them from the exterior structure through the filter assembly and into the external environment.Type: GrantFiled: February 4, 2008Date of Patent: October 5, 2010Assignee: NIF Solutions Corp.Inventor: Timothy P. Zimmerman
