Abstract: A pegboard assembly adapted for the receipt of standard hook and rod devices in both ¼ inch and ⅛ inch thickness which engages the hook portion of such devices at both a vertically disposed front plate and a horizontally disposed top plate so as to insure both firm support and resistance to lateral shift.

Abstract: An attachment device for pressurized fluid dispensing containers enabling augmented directional dispensing through a somewhat flexible tube such as a plastic straw wherein the tube is supported at a position outwardly removed from its positioning vis-à-vis the actuation nozzle and preferably radially outward of the vertical plane formed by the container body wall.

Abstract: The present invention is a plasma antenna that uses an acoustic mechanism to accelerate the ions of the plasma, causing them to radiate electromagnetic energy. A resonant acoustic chamber surrounds the plasma body to produce acoustic pressure waves of very high amplitude and ion accelerations sufficient to generate significant radiation. The resonant chamber is made of a material that is relatively transparent to electromagnetic radiation. Communications information in the form of a modulated frequency is imposed on the signal generated by the plasma by adjusting the resonant frequency of the chamber by changing a parameter of the chamber such as its length or wall stiffness. Varying the acoustic driving force may be used to modulate the amplitude of the radiated signal. Phase modulation may be implemented by lining the ends of the chamber with a material that can quickly alter the position of its reflective face.

Abstract: A closed system adapter for catheters is disclosed. The adapter comprises a rigid outer housing having an inlet end with an internal cavity, and outlet end with a central passageway, the outlet end having a series of incrementally larger diameter steps permitting connection to various sized catheters.Positioned within the inlet end internal cavity is a resilient valve member normally biased to a sealed closed position. The valve member includes a generally cylindrical wall with a diaphragm with a pre-slit partitioned across the wall. The cylindrical wall dimensioned to be slightly larger in diameter than the inlet end cavity of the housing except for a recessed area where the diaphragm is positioned. The cylindrical wall providing inward compressive force except in the recess area permitting the diaphragm to remain in a steady state normally closed position without excessive inwardly compressive force.
