Patent number: 11873061Abstract: A lifesaving handle system for a watercraft surface such as, but not limited to, a boat hull. The handle system remains inside a cavity in an exterior surface of a watercraft hull when the watercraft is upright (i.e., when it is not capsized) such as when it is flowing on a body of water in normal operation. The handle may be rotatably attached to an interior surface of the cavity such that when the boat is upright, as in non-capsized operation, the handle hangs vertically in the closed cavity and is not within the flow of water passing along and around the watercraft hull when the boat is motivated on a body of water; and when the boat is overturned or capsized, the handle rotates out from the closed cavity under the force of gravity such that the grip handle is presented to a person in the water.Type: GrantFiled: May 12, 2023Date of Patent: January 16, 2024Inventor: James Salmela

Patent number: 10823309Abstract: Retractable handle assembly used in a valve of an Intermediate bulk container (IBC) includes a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle is rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. The handle can be switched between a deployed state and a retracted state.Type: GrantFiled: January 20, 2014Date of Patent: November 3, 2020Assignee: SHANGHAI HONGYAN RETURNABLE TRANSIT PACKAGINGS CO.

Patent number: 8852443Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.Type: GrantFiled: September 12, 2007Date of Patent: October 7, 2014Assignee: Cummins Filtration IP, Inc.Inventors: Todd Forrest, J. Bruce Schelkopf, Ted S. Loftis, Barry Verdegan, Wassem Abdalla, Mark Wieczorek, Gérard Malgorn, Charles W. Hawkins, Chad Thomas, Joe Saxon, Mark Johnson, Naren Shaam

Patent number: 8727304Abstract: A pinch bar for a pinch valve is comprised of a coil spring coupled to one end of an actuating rod. An opposite end of the rod is formed with, or is coupled to a device or surface, which applies a pinch force. The actuating rod slides through a fixed-in-place rod actuator. The rod actuator, spring and actuating rod thus provide a mechanism that applies a closing force inwardly, into or directed toward a cabinet attached to which is a valve body for the pinch bar and against which the pinch bar could exert a tube-closing force.Type: GrantFiled: June 27, 2011Date of Patent: May 20, 2014Assignee: Prince Castle, LLC.Inventors: Loren Veltrop, Christopher Lyons, Michael Pearson

Patent number: 8444112Abstract: A locking Y-valve has branches that can be independently locked open or locked closed. Each branch has a ball valve connected to a rotating valve column. The valve column extends through a lock plate and attaches to a housing that contains a locking mechanism. The locking mechanism has a retractable lock pin that cooperates with two recesses in the lock plate to keep the housing, valve column, and ball valve locked in place. The locking mechanism is attached to a rotatable handle outside the housing. Rotating the handle retracts the lock pin from a recess so that the handle can be moved. Releasing the handle extends the lock pin into a recess, securing the handle in place. One or more of the lock plate and housing may be integral with the Y-valve. In the preferred embodiment, the lock plate is configured to be retrofit onto existing Y-valves, so that a non-lockable Y-valve may be converted into a lockable Y-valve.Type: GrantFiled: October 20, 2010Date of Patent: May 21, 2013Inventors: Michael Cravener, Tom Conner

Patent number: 5288053Abstract: This invention is directed to a discharge controlling device for faucet, characterized in that a control lever is used to push a throttle pin axially positioned within the center of the inner sleeve, such that the pin is slidably moved up and down and engages a steel ball which is designed to control the opening and closing of a water discharge aperture. As the control lever is pushed by hand and moved from its lowest closed position to the intermediate, open position where the water can be admitted, the steel ball is pushed away from the aperture by the rod tip of the throttle pin which rises axially. At this instant, water enters the inner sleeve through the aperture and flows out of the housing. When the hand is released from the control lever, the throttle pin will fall, and the steel ball, which is subject to water pressure, will immediately return to the position where it closes the aperture.Type: GrantFiled: June 1, 1993Date of Patent: February 22, 1994Inventor: Andy Y.
