Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
