Abstract: A fluid pumping system includes a number of stages. Each stage has a fluid chamber having a top end with an air aperture and a bottom end with a fluid apertures. An air line is connected to the air aperture, and a fluid input conduit, with an input check valve, is connected to the fluid aperture. A float valve is disposed in the chamber directly between the fluid aperture and the air aperture. A fluid output conduit is connected to the fluid aperture above the input check valve. The float has a bottom end adapted to seal with the fluid aperture when the chamber is empty. A first set of pumping stages are supplied by a first compressed air line and a second set of pumping stages are supplied by a second compressed air line. Periodically, compressed air is supplied to a first set of pump stages to drive fluid from each of the first set of pump stages to a second set of stages, and vice versa.

Abstract: Preferably, each anchor incorporates a passage for receiving boding cement therein. The passage communicates with one or more fenestrations or holes, preferably formed at the distal end of the anchor, that allow the bonding cement to pass from and disperse about the anchor. Since at least some of the bonding cement received in the passage passes from the anchor and, preferably, into the material of the skeletal member to which the anchor is engaged, a firm fixation or anchoring of the anchor within the skeletal member is facilitated.

Abstract: The present invention provides a propulsion system mounted in the hull of a marine vessel. The system includes a conduit system with water intake openings defined in the port and starboard portions of the hull adjacent the bow. Water intake conduits conduct water from the water intake openings to a collection chamber. Water discharge conduits conduct water from the collection chamber to water discharge openings. At least one impeller is mounted in each of said discharge conduits. A valve system is mounted in the conduit system and is selectively operable to isolate the system and prevent the flow of water through the system. A water pump may be used to evacuate water from the system when the valves are closed. A further preferred feature provides access to the impeller portion of the propulsion system. A conduit extension section diverges from the conduit system with one end above the level of the vessel's waterline. A sealable hatch is mounted to the conduit extension.

Abstract: The invention concerns a device wherein the bars (13) are arranged in bulk in the container (5). The mobile frame (17) of the grasping mechanism (14) moves forward such that the jaw (24) can seize a bar by its middle part and remove it in position (13a) while the trolleys (37) move away from the rail (36) so that the rollers slide on the rods (43), gradually lift the whole bar and bring it to rest on the receptacle (16). The shaft (49) is then driven in rotation so that the racks (47) and the support plate segments (46), which form the receptacle (16), move upwards and the bar (13) drops in the supply channel (8) where it is hooked to the bar clamp of the bar-pusher which drives it axially into the turning center control members.

Abstract: A trackable medical instrument includes a guide member and an emitter array coupled to the guide member. A drive shaft is rotatably coupled to the guide member, and a locking mechanism is provided along the drive shaft. The emitter array emits a signal that is used to track the position of the guide member. The locking mechanism has an unlocked position in which the drive shaft rotates relative to the guide member. The locking mechanism also has a locked position in which the drive shaft is rotationally stationary relative to the guide member. A processor tracks medical instruments using a sensor array and a reference array. A display that is operatively coupled to the processor displays the position of the instrument in relation to a patient.

Abstract: A fluid filter has a filter element for filtering fluid. A nutplate having a threaded mounting portion is adapted to threadedly engage an externally threaded filter head. An inner seal retainer is positioned between the nutplate and the filtering element in order to define a hollow interior. The inner seal retainer has at least one stiff hollow web extending in a radial direction adapted to provide a space for transmitting fluid between the nutplate and the filter element. An inner radial seal is attached to the inner seal retainer for sealing the filter element with the filter head.

Abstract: A device for driving a part, including a parts driver having a drive axis and a nosepiece including three jaws arranged uniformly about the drive axis and defining an axial drive passage therebetween. The jaws are resiliently biased toward one another and are transitionable between a first configuration to retain the part within the drive passage and a second configuration to allow the part to be discharged from the drive passage by the parts driver. An adjacent pair of the jaws defines a transverse parts feed passage intersecting the drive passage and being oriented at an oblique angle relative to the drive axis. Each of the adjacent pair of jaws defines a substantially symmetrical portion of the feed passage.

Abstract: A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a stand pipe that is constructed and arranged to deliver fluid. A vane assembly is adapted to receive fluid from the stand pipe. The vane assembly includes a liner and a plurality of vanes. The liner defines an inner cavity and the vanes extends within this inner cavity. Each of the vanes has a radially outer edge portion and integrally formed with the liner and an opposite free edge. The vanes are oriented in a parallel relationship with the stand pipe, and the free edges of the vanes define a stand pipe passage in which the stand pipe is received.

Abstract: A nickel base powder metallurgy superalloy gas turbine engine disk for a compressor or turbine. The wrought powder metallurgy gas turbine engine disk has desirable fatigue crack growth resistance and a superior balance of tensile, creep rupture and low cycle fatigue strength characteristics. In one embodiment the disk defines a segregation free homogenous structure.

Abstract: An apparatus and method for collecting a sample from a low-yield well or perched aquifer includes a pump and a controller responsive to water level sensors for filling a sample reservoir. The controller activates the pump to fill the reservoir when the water level in the well reaches a high level as indicated by the sensor. The controller deactivates the pump when the water level reaches a lower level as indicated by the sensors. The pump continuously activates and deactivates the pump until the sample reservoir is filled with a desired volume, as indicated by a reservoir sensor. At the beginning of each activation cycle, the controller optionally can select to purge an initial quantity of water prior to filling the sample reservoir. The reservoir can be substantially devoid of air and the pump is a low volumetric flow rate pump. Both the pump and the reservoir can be located either inside or outside the well.

Abstract: Devices and methods for utilizing dry chemistry dye indicator systems for body fluid analysis such as glucose level in whole blood are provided by incorporating an indicator in a bibulous matrix contained inside a hollow fiber capillary tube adapted to wick the fluid sample into the tube to wet the matrix and indicator system. The devices also enable visual or meter reading of the indicator by positioning the hollow fiber capillary tube in a housing having an optical opening adapted for receiving light form a source and directing the light to the capillary tube and for directing the light reflected therefrom to a detector. An advantage for the individual user is the small fluid, e.g., blood sample required, which enables the user to avoid using finger tip sticks for samples. Another aspect of the device provides a determination of and correction for hematocrit level in whole blood in combination with indicator indication of analyte concentration.
