Abstract: A cellular seal coating is provided for uses such as assembling composite packages, which cellular seal coating is formed by electrostatically depositing finely divided, electrostatically chargeable bonding agent particles onto a preassembly member. Such bonding agent particles include a chemical blowing or foaming agent or system which forms gas bubbles when heated or otherwise energized in order to alter the thickness and strength of the seal coating so that it may, for example, fill gaps along assembly locations of a package or other article.
Abstract: A connector valve for selectively permitting the transfer of fluids therethrough is described. Multiple-way valve means communicates with a plurality of conduits and selectively permits and prevents flow between the conduits. The multiple-way valve means comprises outer walls made of a substantially ultraviolet-transmissive material, with the outer walls of the multiple-way valve means preferably enclosing an elastomeric seal member defining rotatable channel means for communication with differing conduits at differing rotational positions, and also providing a rotatable seal against inner surfaces of the outer walls to maintain an antimicrobial seal of said conduits. The channel means is exposed along its entire length to an inner surface of an outer wall, to facilitate the anitmicrobial effect of ultraviolet radiation. Also, a novel method of practicing continuous ambulatory peritoneal dialysis, and an ultraviolet light applicator, is disclosed.

Abstract: Apparatus for automatically connecting and disconnecting a pair of connectors includes first and second relatively movable means to carry the connectors and to move them back and forth between connected and disconnected positions. Rack and gear means may be used having a variable mechanical advantage at different positions to facilitate connection and disconnection of the connectors. The apparatus may also have means for providing radiation for antibacterial effect on the connectors, typically ultraviolet radiation.

Abstract: A method for making a hollow fiber separation device including the steps of forming an integral structure which comprises at least one tubular housing portion and an elongated chamber portion extending in elongated relation to the tubular housing portion and communicating with the housing portion adjacent opposed ends thereof. One provides an aperture in a central area of the elongated chamber and inserts hollow fibers for diffusion into the housing portion. One then provides closed ends to the housing portion and spins the structure on an axis between the ends, adding potting compound to the chamber portion through the aperture. Accordingly, the potting compound migrates radially outwardly through the chamber to the closed ends of the housing portion, to encase the ends of the hollow fibers in the potting compound.

Abstract: A disposable electrode assembly for establishing electrical contact with an underlying skin surface includes a relatively thin base member having a central hub portion and an adhesive-coated undersurface, a conductive gel-impregnated sponge contact contained in a downwardly facing recess located in the hub, and a relatively thick and inflexible cover member coextensive with the base member. In storage the cover member is attached to the undersurface of the base member by the adhesive and the sponge is confined within the recess. Prior to use the base member is peeled away from the cover member to expose the adhesive surface, which when applied to a skin surface holds the sponge contact in compression-contact therewith.
