摘要： 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. A purging air flow is directed into the housing to pass across the barrel charging section outer surface and the grounding ring or collar surface to prohibit sorbent particles from collecting on the grounding ring or collar as could interfere with generation of a corona discharge that extends from the charging electrode end portion radially wherethrough the sorbent material particles travel and are electrostatically charged.

摘要： 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. The invention includes a corona enhancement arrangement in the form of a grounding ring or opposing grounding plates arranged in the barrel and spaced apart from the charging wand, that carry a charge that is opposite to the charge on the charging wand enhance the generation of the corona discharge around the charging wand, greatly increasing the sorbent particle charging efficiency to where essentially all the sorbent particles that pass through the gun will receive a surface charge.

摘要： 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.
