Abstract: An integrated valve assembly (10, 110, 210, 310, 410) is provided for pressure-responsive flow control for associated components, such as for nutritional administration to patients. The valve assembly includes a first connector element (12, 112, 212, 312, 412) and a second connector element (14, 114, 214, 314, 414), which are joined to each other, and which respectively define a first, internal flow passage (20, 120, 220, 320, 420) and a second internal flow passage (28, 128, 228, 328, 428). A valve member (40, 140, 240, 340, 440), which may comprise a resiliently deformable slit valve, is positioned between the first connector element (12, 112, 212, 312, 412) and the second connector element (14, 114, 214, 314, 414) for providing pressure-responsive flow control between the first, internal flow passage (20, 120, 220, 320, 420), and the second, internal flow passage (28, 128, 228, 328, 428).

Abstract: The present invention provides for efficient random access to the contents of files encoded with two or more layers of standard or custom encoding. In accordance with an embodiment of the present invention, a file of transaction messages are encoded by dividing the file into multiple discretely-sized, blocks of data are independently encoded. When information in a certain transaction message within the unencoded file is requested, only the encoded block(s) containing that transaction message is decoded.

Abstract: A valve system is provided with a wall portion that includes an inlet side, an outlet side, at least one aperture extending between the inlet and outlet sides, and a valve seat on the outlet side. One preferred form of the valve system also includes a movable valve member having a spout, a mounting portion, a toggle portion, and at least one seal surface for sealingly engaging the wall portion valve seat when the valve member is toggled to a closed position to prevent flow from the wall portion aperture through the spout.

Abstract: A fluid dispenser is provided with a fluid containment unit and a support unit. The fluid containment unit includes a bulb, a nipple, and a tether connecting the bulb to the nipple. The support unit includes a face plate, a retaining ring, and a releasable latch for securing the face plate and retainer ring together to clamp between them the fluid containment unit when the fluid containment unit is in a folded configuration locating the bulb and nipple in communication with each other.

Abstract: A dispensing valve closure (10) is provided which includes a closure body (12) and a cap (14). A self-sealing dispensing valve (16) is disposed within the closure (10) and is held in place with a retaining ring (18). An inner seal (20) is also placed within the closure (10) to allow for sealing on a package.

A self-sealing dispensing valve (16) is disposed within the closure (10) and is held in place with a retaining ring (18). Drain holes (50-56) allow drainage of any fluids built up under the cap (14).

Abstract: A tamper-evident closure is provided with a base having a deck with a discharge aperture. A lid is included for covering the discharge aperture on the base. The lid defines a latch aperture. The base has a resilient locking lever that projects from the base deck and through the lid latch aperture when the lid is closed. The lever engages the lid and holds the lid closed. A tamper-indicating element is provided on the lid to prevent operation of the lever. The element is attached to the lid with frangible portions which can be broken when sufficient force is applied to remove at least a part of the element and permit operation of the lever whereby another part of the element remains on the lid to provide evidence that part of the element has been removed.

Abstract: A flow regulating device and specifically an improved roller clamp with a length of conduit exhibiting low compression set properties disposed therein. The clamp includes an elongated box-like body having a fluid inlet at one end with a fluid outlet at the opposite end which are joined by the conduit to provide a flow lumen through the clamp. The roller is captured within a track in the body to selectively compress or release the conduit towards or away from a compression surface disposed at an angular variance to the track. The flow rate is regulated by appropriately positioning the roller. The conduit is captured within the body so as to be unaffected by external pulling or tugging forces.

Abstract: In a double flow section of a steam turbine, the inner web of the diaphragm surrounding the rotor shaft in the region of divergence of the steam flow paths, is fabricated in the form of two cylindrical shells which are held together either in a fixed position or in a relatively fixed position which permits some slight axial motion between the shells. This form of diaphragm eliminates a number of machining and fabrication alignment problems and additionally permits differential axial expansion of the two pieces occurring as a result of internal thermal steam conditions.
