Patent number: 9526923Abstract: A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can acoustically couple an ultrasound therapy transducer to a patient. In some embodiments, the medical imaging and therapy device is configured to conform to the anatomy of a patient's perineal area to acoustically couple an ultrasound therapy transducer to the patient for treatment of BPH. The medical imaging and therapy device can be used in therapeutic applications such as Histotripsy, Lithotripsy, and HIFU, for example. Methods associated with use of the medical imaging and therapy device are also covered.Type: GrantFiled: June 22, 2015Date of Patent: December 27, 2016Assignees: HISTOSONICS, INC., THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Russell C. Jahnke, James A. Bertolina, William W. Roberts, Charles A. Cain, Dejan Teofilovic, Thomas W. Davison

Patent number: 7726363Abstract: A filler tube assembly for use in a system having vapor recirculation includes a check valve having a flapper that is responsive to the viscosity of fluid around the flapper and/or a differential pressure across the flapper. The assembly also includes a nozzle chamber formed in the filler neck that has a constant diameter to ensure consistent vacuum generation regardless of fuel nozzle length.Type: GrantFiled: January 20, 2006Date of Patent: June 1, 2010Assignee: Eaton CorporationInventors: Robert P. Benjey, Daniel L. Pifer, Russell C. Jahnke

Patent number: 7644740Abstract: A protective cover for a filler neck is designed to discriminate between different sizes of fuel nozzles. The cover includes a body portion and a movable door that covers and exposes an opening in the filler neck. The body portion has a pair of spaced body protrusions that form a gate, and the door has a ledge that may also be formed by a pair of spaced door protrusions. The protrusions on the door can be easily moved to an open position by pressing a tip of a fuel nozzle against the protrusions. The gate and the ledge are configured so that they can accommodate the fuel nozzle for only one type of fuel.Type: GrantFiled: March 1, 2007Date of Patent: January 12, 2010Assignee: Eaton CorporationInventors: Robert P. Benjey, Paul D. Walkowski, Russell C. Jahnke, Andrew W. McIntosh, David Adam Deboskey

Patent number: 7484525Abstract: A failed nozzle relief (FNR) valve has a resetting mechanism that resets the valve when a filler cap is replaced over the filler cup. The FNR valve has an annular seal that surrounds a filler neck opening. The annular seal seats against a ring having at least one aperture that creates an alternative fluid flow path. During a failed nozzle shutoff condition, the annular seal separates from the ring, opening the aperture to allow fluid to flow through it. The FNR valve also has a reset lever that is pressed downward when the filler cap is replaced, thereby forcing the seal back against the ring.Type: GrantFiled: January 20, 2006Date of Patent: February 3, 2009Assignee: Eaton CorporationInventor: Russell C. Jahnke

Patent number: 7147019Abstract: A cover for a filler neck includes a body portion and a movable protective door that covers and exposes an opening in the filler neck. The protective door includes a ledge that protrudes from the plane of the door so that the door can be easily moved to an open position by pressing a tip of a fuel nozzle against the door. The door itself may be biased to move into a closed position automatically when the fuel nozzle is removed from the ledge.Type: GrantFiled: January 31, 2005Date of Patent: December 12, 2006Assignee: Eaton CorporationInventors: Paul D. Walkowski, Robert P. Benjey, Russell C. Jahnke, Andrew W. McIntosh

Publication number: 20030205272Abstract: In a fuel tank having an electric fuel pump therein, the fuel pump is connected to discharge into a venturi with a throat pressure tap line connected to the bottom of a vapor vent valve fed by spider tubes to the tank vapor dome areas. Venturi throat suction pumps liquid accumulated in the vent valve for discharge through the venturi into the tank. A one way valve prevents back flow in the throat pressure tap line to the vent valve. Float operated valves are provided on the ends of the spider tubes to restrict fluid flow to the vapor vent valve.Type: ApplicationFiled: May 2, 2002Publication date: November 6, 2003Applicant: EATON CORPORATIONInventors: Robert P. Benjey, Craig H. Allman, Russell C. Jahnke

Patent number: 6508263Abstract: The float has an elastomeric valve disk with an annular bead rim caged for limited lost motion movement on the top of the float. A rigid backing plate for the valve disk is pivoted on a curved surface on the top of the float to ensure self-alignment of the valve disk on the vent port seat when the float is moved upward by the rising liquid level for closing the vent during refueling. As fuel is used from the tank, the float drops and the angled top of the cage contacts the bead rim on the valve disk and effects a peel-away re-opening of the valve.Type: GrantFiled: September 20, 2001Date of Patent: January 21, 2003Assignee: Eaton CorporationInventors: Russell C. Jahnke, Maxim V. Zorine
