Abstract: A coupling half for interconnecting fire hose or other hose to a reciprocal connection mounted on another hose or on a fixed object. The coupling half includes two slots (14, 42) which enable the manufacturing of the coupling half quickly, efficiently, and inexpensively. Only two molds (33, 34) are us ed to cast the coupling half compared with the traditional three molds. The mol ds (33, 34) are in contact with each other at three radial points with each radial point being separated by the mold cavity. Machining is greatly reduce d as the coupling half is made from one piece as compared with the traditional two pieces. The slots (14, 42) in the locking collar enable the coupling hal f to be made of one piece resulting in less machining.

Title: Filter apparatus for ostium of left atrial appendage
Inventor: HAUSER ROBERT G
IPC: A61F2/01
Filed: 2000-10-26
Granted: 2009-08-04
Abstract: Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e.g., an expansion balloon, to pass therethrough, and wherein the opening is resiliently biased towards the first size.

The multi-tool includes a housing (40) carrying a striker (44) and a magazine (12) bearing a plurality of circumferentially spaced tools (16) and rotatable with respect to the housing so as to bring a single desired tool into alignment with the striker (44). The housing has a striking surface (48) adapted to be engaged by the ram of a punch press and config-ured to rotationally lock to the ram when correctly ro-tationally aligned therewith to prevent the housing from rotating as the magazine is rotated. The housing is pro-vided with at least one alignment pin (60) having a ta-pered cam surface (74) and positioned such that the ram will contact and cam against the tapered cam surface of the pin as the ram approaches the striking surface if the machine ram and the striking surface are rotationally mis-aligned so as to urge the housing to rotate into cor-rect alignment with the ram to enable rotational locking therebetween.

Abstract: A liquid chemical metering pump (24) is described that can be fully submerged within a hazardous liquid chemical transport/storage container (28). The pump (24) includes a discharge adaptor (30) that can be received in the outlet aperture (40) of the container (28), in which it is held in sealing relationship by a suitable screw-threaded connector. The discharge adaptor (30) is provided with an intake port (32) in fluid communication with the liquid chemical in the container (28), and a discharge port (34) which is in fluid communication with a discharge tube (36) leading to a flow stream (38). The chemical metering pump (24) is remotely controlled by an electronic controller (26) connected by cable (25) to the chemical metering pump. The chemical metering pump (24) substantially eliminates the need for "double handling" of hazardous liquid chemical, as the chemical can be metered directly from the transport/storage containers in which it is delivered to the end user. The pump (24) can be readily modified to suit different sized containers.

Title: Multi-purpose float equipment and method
Inventor: MUSSELWHITE JEFFREY D
IPC: E21B34/06
Filed: 2001-03-12
Granted: 2012-02-21
Abstract: A float shoe/collar apparatus (14) and method is disclosed for multi-purpose use in running a tubular string (11) such as a casing string or liner into a wellbore and for optimizing cementing operations. In one presently preferred embodiment, the present invention permits auto filling of the tubular string (11) as the string (11) is lowered into the wellbore. If desired, circulation can be effected through down jets (30) for washing the wellbore as necessary. After the tubular string (11) is positioned, the down jets (30) can be blocked off and up jets (33) opened to thereby direct cement upwardly to optimize cement placement. Check valves (31) can also be activated in accord with the present invention to prevent flow from the wellbore into the tubular string (11). In one embodiment, the invention comprises an inner member (27) and an outer tubular member (25). The inner member (27) is movable upon release of shear pins (28) to cause longitudinal movement relative to the outer member (25). The movement of the inner member (27) may close a plurality of downward jets (30) and may also open a plurality of upward jets (33) if desired. The apparatus (14) may also be equipped with a set of check valves (31) which can be held open on run in, and subsequently activated to thereby automatically close upon cementing to prevent "u- tubing" of fluid back into the casing (11).

Abstract: ABSTRACT To provide a device for designing a standby path that can prevent retrieval of a standby path in a network including any standby path from being failed. A current path search unit searches for a shortest route from a tart point to an end point in the network. A standby path searching,network creation unit creates a standby path searching network. For a standby path, a standby path search unit :searches for a shortest route from the start point to each of all other nodes including the end point. A current path searching network creation unit creates a network from the current path retrieved by the current path search unit and the path retrieved by the standby path search unit. The process performed by these units is repeated until the standby path search unit retrieves a route that reaches from the start point to the end point in the shortest route search.

Abstract: The invention relates to an axle guide consisting of a fibre-synthetic material composite for guiding an axle in the running gear of a rail vehicle, in particular a high-speed rail vehicle. Said guide has two end sections (11, 11') for connecting the guide (1) both to the axle and to the chassis (2) of the running gear in a manner resistant to torsion and a central section (12) located therebetween, which has a longitudinal axis (13) aligned with the direction of travel (X) and a cross-section that is at least partially flat in the vertical direction (Z). The guide (1) has at least one integrated flexural joint (14) with a vertical flexural axis (15) and enables a rotational degree of freedom, which protects the wheel bearing from damaging flexural stresses, to be achieved simply without the need for an additional joint component. The inventive guide also benefits from all the advantages of the glass fibre-synthetic material composite, such as adjustable rigidity that can be reproduced with narrow tolerances and that is defined almost independently of the temperature, resistance to wear, electric insulation, excellent material damping properties and favourable behaviour if a malfunction occurs.
