BYPASS VALVE

A bypass valve () that regulates a flow of a fluid in a waste heat recovery system () is provided. The bypass valve () comprises a valve housing (), an expander poppet () coupled to the valve housing () and adapted to prevent the flow of the fluid to an expander (), and a valve stem () with at least a portion disposed in the valve housing () wherein the valve stem () is adapted to displace the expander poppet () to allow the fluid to flow to the expander (), and regulate the flow of the fluid.

Valve with bearing isolation

A valve (100, 600) coupled to a conduit carrying a fluid is provided. The valve comprises a shaft (210, 610) disposed through a wall of the conduit, a fluid flow regulating means (230) coupled to the shaft (210, 610) inside the conduit, a rotatable support means (110, 320) coupled to the shaft (210, 610) outside the wall of the conduit, and a proximate bearing (310) coupled to the shaft (210, 610) at a distance from the rotatable support means (110, 320) wherein the proximate bearing (310) is coupled to the conduit via one or more isolation means (120, 130).

Positive completion coupler insert and coupler

A positive completion coupler insert (100) configured to be inserted into a coupler (150) is provided according to the invention. The coupler insert (100) includes a conduit support insert (110) configured to be retained in a coupler bore ( 151 ) of the coupler (150) and a conduit support (140) configured to fit into and be retained by the conduit support insert (110). The conduit support (140) is configured to generate a first audible sound when inserted to a first insertion point in the conduit support insert (110) and is configured to generate a second audible sound when inserted to a second insertion point.

A flapper assembly for a throttle valve

A method of forming a flapper assembly (200) for a throttle valve (100) is provided. The method includes steps of forming a flapper (110) comprised of hub (112) having an opening (114) and at least one vane (116a,b) coupled to the hub (112), disposing a shaft (210) in the opening (114), and pressing a punch (P) into an outer surface (112a) of the hub (112) such that a torque dimple (118) extends from the hub (112) into the shaft (210) to fasten the flapper (110) to the shaft (210).

Seat height control system

The present invention relates to a leveling valve (20) including a first port (23), a second port (24), a third port (25), a valve (70), and a clutch (30). The clutch is provided with an engaged position and a disengaged position. At least a portion of the clutch may move relative to the valve when the clutch is in the disengaged position. The clutch moves the valve when the clutch is in the engaged position. The valve is movable between a first position, a second position, and a third position. When the valve is in the first position, the valve blocks a first pathway, which extends from the first port, from connecting with a second pathway, which extends from the second port. When the valve is in the second position, the valve allows the first pathway to connect with the second pathway. When the valve is in the third position, the valve allows the second pathway to connect with a third pathway, which extends from the third port.

Interactive Book

An interactive book or device (100) having a mechanism for generating a plurality of sensory outputs in a manner that maximizes the interaction between the user and the book or device. The interactive book includes function initiators (106) for initiating a unique sensory output that corresponds to a visual indicia (114) on a page of the book (104). A function level selector (108) is coupled to the function initiators (106) that selectively changes a function level and thereby selectively changes the sensory output corresponding to each function initiator (106). Consequently, the number of sensory outputs is increased and thereby enables greater interaction between the user and the book. It also encourages the user to creatively combine the sensory outputs to obtain a cognizable aggregate output.
