Abstract: An injection syringe for injecting a fluid into the arterial, venous, muscular or cavity structures of a patient via subcutaneous, percutaneous, intravascular and other types of injections comprises a hollow syringe body, a passageway at a distal end of the syringe for passage of fluid into and out of the syringe and a substantially open proximal end for receiving a plunger assembly. The plunger assembly includes a movable plunger assembly. A moveable plunger cooperates with the syringe body and the proximal end of the syringe to define a fluid chamber of variable volume in fluid communication with the passageway. Actuating means actuates movement of the plunger. An elastomeric barrier cooperates with the plunger and the open end of the syringe to define a sterile chamber between the actuating means and the fluid chamber to prevent passage of fluids from the fluid chamber to the actuating means and the passage of contaminants from the open end of the syringe in the fluid chamber.

Abstract: A powder injection molding composition or feedstock is made of 70% or more by weight of a powdered metal or ceramic and 30% or less by weight of a binder system. The binder system contains a sufficient amount of polypropylene or polyethylene to hold the so-called brown preform of the molded metal or ceramic powder together for the sintering step of the injection molding process and a sufficient amount of partially hydrolyzed cold water soluble polyvinyl alcohol, water and plasticizer to facilitate molding of the composition into the so-called green preform of the article to be manufactured. The debinding step of the injection molding process for transforming the green preform into the brown preform consists simply of immersing the green preform in water at ambient temperature to dissolve the polyvinyl alcohol. The binder system is nonhazardous, safe, harmless and fully degradable.

Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75.degree. TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.

Abstract: A sampling apparatus is characterized by a sampler housing coupled to a movable valve of a connecting device. The housing and the movable valve have bores that are in communication and axial alignment. One end of the valve bore communicates with the interior of a liquid containing vessel. A plunger is in the housing bore and has an annular recess intermediate its ends. The plunger is reciprocated in the housing and valve bores to project the recess into the vessel to receive a sample of liquid therein, and to then retract the recess from the vessel and through the valve and housing bores to a sample collection point in the housing. Plunger seals maintain a liquid seal between the vessel interior and the sample collection point in the housing during reciprocation of the plunger. The valve is movable between an operative position where the one end of its bore communicates with the vessel interior and an inoperative position where the one end of its bore is out of communication with the vessel interior.
