Abstract: A dual isolation valve (10) comprises: a valve body (12) with opposed inlet (14) and outlet ports (40) that defines an inner cavity; a first valve member (22); and a second valve member (34). The valve members (22, 34) (preferably plugs) have narrower first ends (22a, 34a) and wider second ends (22b, 34b) and are rotatably mounted within the valve body cavity for rotation about a first and second axis of rotation substantially perpendicular to the flow axis F defined by the inlet and outlet ports (40). The valve members include substantially rectangular flow passages (24, 36). The first ends of the valve members extend away from the second ends along the first and second axis of rotation in opposed directions, and the valve members are rotatable between an open position, in which the flow passages (24, 36) are oriented to be generally aligned with and located on the flow axis F to enable fluid entering the inlet port to pass through the flow passage, and a closed position, in which the flow passages (24, 36) are oriented to be generally perpendicular to the flow axis F to enable fluid entering the inlet port to pass through the flow passage, and a closed position, in which the flow passages are oriented to be generally perpendicular to the flow axis F to prevent fluid entering the inlet port from passing through the flow passage. In this configuration, the flow of fluid through valve can be disturbed less than with prior art dual isolation valves while permitting extensive flow through the valve.

Title: Biopsy site marker and process and apparatus for applying it
Inventor: FORCIER NANCY
IPC: A61K49/04
Filed: 2000-06-28
Granted: 2009-09-29
Abstract: A biopsy site marker comprises small bodies or pellets (20) of gelatin which enclose substantially in their interior a radio (X-ray) opaque object. The gelatin pellets are deposited into the biopsy site, typically a cylindrical opening in the tissue created by the recent use of a vacuum assisted large core biopsy device, by an applicator device that includes an elongated cylindrical body that forms a flexible tube (26) and a piston (28) slidable in the tube. One end of the tube is placed into the biopsy site. Typically, sev-eral gelatin pellets, only some of which typically do, but all of which may contain the radio opaque object, are deposited sequentially into the site through the tube. The radio opaque objects contained in the gelatin bodies are of a non-biological configuration and readily identifiable as man-made object, so that in observation by typical mammography equipment they do not assume the shape of a line, whereby they are readily distinguishable from granules and lines of calcification.

Abstract: In a fuel cell assembly typically consisting of a plurality of cells each comprising an electrolyte layer (2), a pair of gas diffusion electrode layer s (3, 4) interposing the electrolyte layer between them, and a pair of flow distribution plates (5) for defining passages (10, 11) for fuel and oxidizer gases that contact the gas diffusion electrode layers, the electrolyte layer (2) comprises a frame (21) including a grid (21a) having a number of through holes (21b), and electrolyte (22) retained in each of the through holes. Because the electrolyte is not required to be interposed between structural members such as the gas diffusion electrode layers and flow distribution plates, the electrolyte is allowed to expand into the passages for the fuel and oxidizer gases to that no undesirable stresses are produced, and the structural members would not be affected by the expansion of the electrolyte .

Granted: 2007-01-16
Abstract: A system and process is provided for producing spunbond nonwoven fabric. Two or more polymeric components are separately melted and are separately directed through a distribution plate configured so that the separate molten polymer components combine at a multiplicity of spinneret orifices to form filaments containing the two or more polymer components. Multicomponent filaments are extruded from the spinneret orifices into a quench chamber where quench air is directed from a first independently controllable blower and into contact with the filaments to cool and solidify the filaments. The filaments and the quench air are directed into and through a filament attenuator and the filaments are pneumatically attenuated and stretched. The filaments are directed from the attenuator into and through a filament depositing unit and are deposited randomly upon a moving continuous air-permeable belt to form a nonwoven web of substantially continuous filaments. Suction air from a second independently controllable blower beneath the air-permeable belt so is drawn through the depositing unit and through the air-permeable belt and web is then directed through a bonder for bonding the filaments to convert the web into a coherent nonwoven fabric.

Abstract: The present invention provides for retractable Coverings for architectural openings utilizing a control system having a single operating dement allowing a user to move a retractable covering between extended and retracted positions by imparting a repetitive motion to the operating element. The Control system may include an input assembly, a transmission, and an output assembly cooperatively engaging to convert linear movement of the operating element into rotational movement of a head roller in the required direction to provide movement of the covering in the desired direction and distance. The input assembly may convert linear movement of the operating element onto rotational movement imparted to the transmission. The input assembly may also engage the transmission to effect the direction of rotational output from the transmission. The transmission imparts rotational movement to the output assembly, which interfaces with the head roller to rotate the head roller and to provide a braking feature.
