Abstract: Syringes and methods of using are described which protect the syringe barrel cavity from contaminants. A first syringe is formed with a corrugated sheath which encloses the plunger and space between the rearward end face surface of the syringe barrel handle member and the forward face of the plunger handle member. A second syringe is formed with a syringe barrel having a straight segment and a corrugated segment having the forward face of the plunger handle member molded to the rearward terminus of the corrugated segment of the syringe barrel. A third syringe is formed from mating syringe barrel and plunger member walls. The walls of the mating syringe barrel and plunger member are concentric and slide relative to each other while maintaining an enclosure around the plunger shaft. A fourth syringe is formed from inner and outer concentric syringe barrel walls mating with the walls of a plunger member.

Abstract: Purified and isolated nucleic acid is provided which encodes a transferrin receptor protein of a strain of Haemophilus or a fragment or an analog of the transferrin receptor protein. The nucleic acid sequence may be used to produce peptides free of contaminants derived from bacteria normally containing the Tbp1 or Tbp2 proteins for purposes of diagnostics and medical treatment. Furthermore, the nucleic acid molecule may be used in the diagnosis of infection. Also provided are recombinant Tbp1 or Tbp2 and methods for purification of the same. Live vectors expressing epitopes of transferrin receptor protein for vaccination are provided.

Abstract: A method for improving the quality of printing processes involving black pixel depletion by printing composite ink in pixel spaces where a black pixel depletion process leaves unfilled pixel spaces. Black pixel depletion data are employed (for example, a depletion mask is inverted) to generate a composite printing mask which designates pixel spaces which are candidates for being filled in with a composite ink. In a preferred embodiment, edge pixels of black fill areas are excluded from the candidate pixels. In a preferred embodiment, the white pixel spaces are filled in by printing a plurality of different colored inks (e.g., cyan/magenta/yellow or cyan/magenta) within these unfilled pixel spaces. In a preferred embodiment, the composite printing mask additionally serves as an under/overprinting (UOP) map.

Abstract: A document scanner carriage drive belt tensioner includes a pivotally mounted base with integrally formed retainers on the base and scanner housing for holding the base in one of three positions comprising a tensioner spring removal position, a carriage belt installation position and an operative or carriage belt tensioning position, all without the necessity of disconnection of any tensioner fasteners. The tensioner is therefore easily operable by an unskilled user to replace the tensioner spring or scanner carriage drive belt when necessary.

Abstract: A medical port for an emergency safety resuscitator having a collapsible bag with an outlet. An adapter has a first end available for attachment to, and communication with, the outlet of the collapsible bag. A second end of the adapter attaches to a first aperture of a tube having three apertures. The second aperture of the tube is releasably covered by a self-sealing membrane. And the third aperture of the tube is available for connection either to a mask or an endotracheal tube.

Abstract: A resuscitator having a collapsible bag with an inlet for attachment to a source of oxygen. The collapsible bag has a major outlet and a minor outlet. The major outlet is connected to a first arm of a three-armed connector. The minor outlet is attached to a flexible tube which, in turn, may either be connected to an adapter that is connected to the second arm of the three-armed connector or to a nebulizer or aerosolizer that is attached to the second arm of the three-armed connector. The third arm of the three-armed connector is connected to a housing containing a one-way valve to permit the flow of oxygen away from the collapsible bag and to preclude the flow of liquids and gases toward the collapsible bag. Preferably, the housing also contains, between the one-way valve and the second end of the housing, an exhaust aperture; and the exhaust aperture is preferably covered by a filter.
