Abstract: Among other things, there is shown a system for filling vials with fluid that maintains a localized sterile zone around the filling location. In particular embodiments, the sterile zone is provided by a manifold having an internal space to which clean air is supplied. One or more filling assemblies are attached to the manifold. Vials enter the sterile zone and are filled within it. Additional structure, such as coverings for vials, are disclosed to assist in maintaining sterility.

Abstract: A purging electrostatic gun for uniformly and essentially completely electrostatically charging the outer surfaces of a flow of sorbent material particles passed therethrough under pressure that are then injected into a polluted gas stream for contacting to electrostatically attract and react to pollutant particles and pollutant gases in that gas stream that are then removed in a conventional pollution control filtration device. The purging electrostatic gun includes a housing wherein a charging electrode is maintained that is electrically coupled to receive a high voltage and is axially centered in a cylindrical barrel charging section wherethrough a laminar flow of sorbent material is directed. The charging electrode has a forward portion that extends beyond a barrel charging section forward end and is immediately opposite to a surface of a grounding ring or collar. The grounding ring or collar is maintained in the housing and is connected to earth ground.

Abstract: An electrostatic gun for electrostatically charging and injecting sorbent particles into a flue gas stream to contact, and electrostatically charge, pollution particles in that flue gas stream. The electrostatic gun is for inclusion as a component of an apparatus for the remediation of pollution particles from a flue gas stream whereafter the clean gas flow is vented to atmosphere. The electrostatic gun receives laminar flow of a selected sorbent material and charges, either positively or negatively, the surface of each sorbent particle in that flow. To provide electrostatic charging to the individual particles, the flow is directed through a straight barrel of a housing of the electrostatic gun to pass alongside a charging wand that is centered axially in the straight barrel. The charging wand is connected to receive a voltage from a high voltage power supply to produce a corona discharge wherethrough the sorbent materials pass to electrostatically charge each sorbent particle.

Abstract: End terminating means (30,32) for a zip fastener (10), which comprises two strips of material (12,14) adapted to be releasably secured together, is in the form of a receptacle (FIG. 2a) having an open end through which adjacent ends of the strips are inserted. The receptacle has a dove-tailed lid (42) pivoted above an opening in the receptacle and incorporating barbs (48,50) adapted to hook into the strips (12,14) to retain them in the receptacle. The lid engages the edges of the opening to lock it in the closed position.
