Abstract:
A Nuclear Magnetic Resonance (NMR) probe including a conduit to provide a sample, a measurement region in fluid communication with the conduit, and at least one restriction element to at least partially restrict flow of the sample from the measurement region in at least one flow direction.
Abstract:
The drogue 11 comprises a canopy 50 supported by a plurality of adjustable ribs 42 and further ribs 43. A control unit 36 is provided for moving the adjustable ribs 42 into a first position P1, in which an air stream can inflate the canopy 50 whereby drag on the canopy causes the drogue 11 to draw a fuel hose 74 from a tanker aircraft 63 into an extended position, and into a second position P2 in which the canopy 50 takes on a cylindrical form and drag thereon in the extended position will be reduced. Selected adjustable supports are movable relative to the others by a control mechanism 41 to adjust a selected portion of the canopy 50 whereby the drag on that portion will be increased and the drogue 11 will move to a new position.
Abstract:
Vibration damping apparatus (40) includes a body in the form of backup roll balance piston (42) positionable for sliding movement in an enclosure in the form of cavity (44) in the lower backup roll chock (30) of the mill stack (10). The body of the piston is a casing which performs the role of a conventional postion. A damping means is integral with the piston (42) for providing vibration damping of opposing backup roll chocks (24, 30). The damping means is a specially designed absorption system to provide tuned stiffness and damping elements which act in parallel and are located in compartment (46) at an uppermost end or cap of the piston (42). A second vibration absorbent compartment portion (56) of the piston (42) also includes vibration absorbing components. Portion (56) is an integral cap located at the end of the piston (42) in contact with the fluid (52).
Abstract:
A head stack assembly for mounting to a pivot bearing cartridge in a disk drive includes a coil having opposite electrical ends and a unitary molded plastic E-block fabricated from a first thermoplastic material containing electrically conductive filler material such that the E-block is electrically conductive. The E-block defines a generally cylindrically shaped body portion and a plurality of elongated arms, the body portion having a pivot bore for receiving the pivot bearing cartridge, a plurality of spaced-apart arm-support regions, and a surface defining a mounting site. Each arm is cantilevered from a respective one of the arm-support regions to project radially away from the pivot bore. The head stack assembly further includes an overmolded coil frame securing the coil to the body portion such that the coil is cantilevered to project radially away from the pivot bore. The overmolded coil frame is fabricated from a second thermoplastic material and is electrically non-conductive. The head stack assembly further includes a flex circuit cable having a portion secured at the mounting site, the flex circuit cable including a plurality of conductors, an electrical path from a first one of the conductors to provide ground potential to the E-block, and a pair of electrical paths from a second and a third of the conductors to the opposite electrical ends of the coil.
Abstract:
A distribution apparatus for transporting an article struck from sheet metal is disclosed, which includes a receiving head having a recess for receiving the article struck from the sheet. The recess includes a resilient interference feature extending inwardly beyond the boundary of the article to be received. Transporting apparatus is further provided for transporting the receiving head to a selected destination and, finally, a discharging element is included for discharging the article from the receiving head at the selected destination.
Abstract:
A file cabinet is disclosed which has a door with high sound absorption properties. The door has metal front and rear panels and an intermediate layer of sound absorbing material sandwiched therebetween. An array of openings are cut through both the front and rear panel. Sound impinging on the front panel enters the cabinet via the door and is attenuated in the door and cabinet. Preferably, paper files are stored within the file cabinet with their peripheral edge surfaces disposed towards the rear panel to assist in attenuating sound within the cabinet.
Abstract:
An improved intravenous catheter/heparin lock combination having a tip, a body, an IV port and a movable hollow plug; the exterior of the plug having a self-sealing membrane through which needles may be inserted. The plug is movable within the body so as to function as a valve in relation to fluid flow through the port.A method of using the combination wherein the plug may be positioned to control fluid flow through the port and medications may be administered by needle through the plug independently of fluid flow through the port.
Abstract:
A method and apparatus for sterilization wherein a flexible, non-resilient, filamentar electrode having an exposed cauterizing tip at one end thereof, and having a thin, dielectric, lubricous covering insulating the electrode up to the exposed tip, is inserted into a severed vas deferens. The electrode insertion is continued until the tip has been located a predetermined distance into the vas. This distance is less than the covering length so that the tip is contiguous with the inner vas walls but the remainder of the electrode is completely insulated therefrom. A second electrode is placed in electrical contact with the patient's body. A radio frequency (r.f.) energy source is applied to the other electrode end to cause r.f. energy flow from the tip to the inner vas wall. The tip is then withdrawn at a predetermined rate while applying r.f. energy to the electrode to thereby cauterize the inner walls which join together in permanent sperm-sealing relation.
