    摘要: A monolithic earplug being compressible or deformable. The earplug is fabricated from an extruded, elastomeric thermoplastic in order that it may be rapidly and efficiently produced, and then the extrudate is cut at the die face, as it emerges therefrom, into discrete pieces to form earplugs having convex end portions and a skin extending over its entire outer surface.

    摘要: Method and apparatus for a laterally extendable backup light system for placement on the trailer of the 18-wheeler tractor trailer truck. The backup light would be mounted underneath an outer edge of the trailer of the tractor-trailer so that it would be extendable laterally away from the edge of the trailer so that the light portion would extend far enough outwardly to travel beyond the outer edge of the trailer so that the beam of light emanating therefrom would illuminate the area behind the rear of the trailer. A linear actuator controlled wirelessly or via hardwire by the driver of the truck would actuate the light portion of the device so that the light portion would extend from an enclosure beyond the edge of the trailer of the truck-trailer or would be retracted back into the enclosure.

    摘要: An improved liquid handling needle device for use with the reconstitution of toxic drugs such as those used in chemotherapy and other applications. When diluent, in this example, is added through a septum into a sealed container, a positive pressure builds up. Aerosols containing the reconstituted drugs can be release through the punctured opening exposing personnel to potential contamination. This improved needle device provides a low-cost aerosol resistant vent channel between the outside diameter of the needle and the inside diameter of the tubular member holding it allowing gas diffusion from inside of the sealed container through the vent channel to the outside of the container when said needle device is inserted into the sealed container. This specifically engineered aerosol resistant vent channel prohibits the flow of the aerosol particles from flowing due to the frictional contact of the aerosol particles with either of the opposing walls forming the vent channel causing any aerosol particles to condense and be redirected back into the liquid receiving sealed container, thus providing sterile air venting for both the injecting and withdrawal of fluids.

    摘要: A lubricated ball bearing for use in ball bearing sets is disclosed. The lubricated ball bearing features a lubricating coating applied to its outer surface. The lubricating coating preferably comprises silver, and enables the ball bearing to be utilized in bearing assemblies environments where other lubricants may not be acceptably used, such as in the high vacuum environment of an x-ray tube. The lubricating coating is attached to the ball bearing via an intermediate bonding layer that is interposed between the outer surface of the ball bearing core and the lubricating coating. The intermediate bonding layer, preferably comprising nickel, is chemically bonded to both the ball bearing core and the lubricating coating. This produces a lubricating coating having a high-strength adhesion to the ball bearing such that flaking or degrading of the coating will not occur in the high heat, high vacuum environment of the x-ray tube during x-ray production.

    摘要: A positive displacement liquid drawing and dispensing apparatus (21) having a tubular member (22) with an axially extending lumen (24) and a plunger (31) mounted for axial displacement in the lumen (24). The plunger (31) has a first seal (33) positioned proximate an end (34) of the plunger and a second seal (37) axially spaced from the first seal (33). The first and second seal each slidably and sealingly engage an interior surface (23) defining the lumen (24) as the plunger (31) is displaced in the lumen. The plunger further includes a recess (38) intermediate the first and second seals for receipt of trapped gas (40,41) which can be drawn in through an intake end (27) of the lumen during drawing of the liquid (36) into the tubular member (22). The plunger is formed for positioning of the first seal (33) beyond the intake opening (27) so that air will automatically be isolated between the first and second seals (33,37) as the plunger is withdrawn into a lumen. A substantially gas-free draw of liquid will result between the first seal (33) and the intake opening (27). A method of drawing the liquid in the apparatus which includes automatically isolating an uppermost portion of the liquid (36) and gas (41) from a lower portion of the volume drawn into the apparatus (21).

    摘要: A baffle assembly (23) positioned between a pipetter assembly (10) and a disposable pipette tip (16) for substantially reducing transfer of aerosol and/or fluid specimens to the pipetter. The baffle assembly (23) includes a barrier structure (25) extending transversely across a receiving chamber (17) of the pipette tip (16) and defines at least one narrow passageway (26) extending generally in the direction of the longitudinal axis (27) through the barrier member (25) between an entrance (30) and an exit (31) thereof. The passageway (26) includes a first wall (32) extending generally transverse, and preferably perpendicular to, the longitudinal axis (27) of the pipette tip to define at least one elbow portion positioned between the entrance (30) and the exit (31) of the passageway. A filter membrane (55) preferably is secured across the passageway (26) to reduce aerosol transport through the passageway (26). A method for substantially reducing transfer of aerosol and/or fluid to the pipetter (10) is also provided, as is a method for securing the filter (55) to the baffle assembly (23).

    摘要: A method and apparatus for forming and dispensing a coating material formulation or solution containing a liquid coating composition and a fluid diluent such as a supercritical fluid comprises a supply for the liquid coating composition, a supply for the fluid diluent, a mixer for combining the two components to form the coating material solution or formulation, and a control system for monitoring a parameter of the formulation which can be correlated to the fluid diluent content and/or liquid coating composition content of the formulation, and for monitoring the pressure of the formulation at selected locations within the system. The control system is effective to open or close the supply of fluid diluent and/or liquid coating composition in accordance with variations in the formulation parameter which is being sensed, and in response to pressure changes within the system, to maintain single or multiple phase coating material formulations, to account for changes in a parameter of the liquid coating composition and to ensure that the desired ratio of fluid diluent to liquid coating composition is maintained in the formulation which is supplied to coating dispensers for deposition onto a substrate.
