Abstract
Abstract An enclosure surrounds a jet device for fluid treating a threadline passing through the enclosure. The jet device has a curved surface positioned with respect to the threadline, the stream-forming orifice of the jet and a wall of the enclosure to divert the treating fluid traveling along the threadline away from the threadline and redirect it across the threadline near the threadline passage openings in the enclosure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
An apparatus for reducing fluid flow from inlet and outlet ports in an enclosure through which a threadline passes in a substantially straight path for treatment in a fluid stream, said apparatus comprising the combination of an enclosure forming a chamber having upper, lower, front and backwalls, there being an exhaust port in communication with the chamber through the backwall and aligned inlet and outlet ports through the upper and lower walls respectively for passage of the threadline to and from a jet device mounted on said backwall, said jet device having a stream forming orifice and an opposed plate positioned on opposite sides of said path; means connected to said exhaust port for exhausting said chamber; means for supplying pressurized fluid to said jet; and a stream guiding member positioned adjacent said orifice, said member having a curved surface sloping gradually away from the threadline path toward said backwall.
Claim 2
Independent Claim
150 words
An apparatus for reducing fluid flow from inlet and outlet ports in an enclosure through which a threadline passes in a substantially straight path for treatment in a fluid stream, said apparatus comprising the combination of an enclosure forming a chamber having upper, lower, front and backwalls, there being an exhaust port in communication with the chamber through the backwall and aligned inlet and outlet ports through the upper and lower walls respectively for passage of the threadline to and from a jet device mounted on said backwall, said jet device having a stream forming orifice and an opposed plate positioned on opposite sides of said path; means connected to said exhaust port for exhausting said chamber; means for supplying pressurized fluid to said jet; and a stream guiding member positioned adjacent said orifice, said member having a curved surface sloping gradually away from the threadline path toward said backwall.
Claim 3
Dependent Claim
24 words
The apparatus as defined in claim 1, said curved surface sloping gradually away from the central axis of the threadline in an upwardly direction.
Claim 4
Dependent Claim
22 words
The apparatus as defined in claim 2, the curvature of the curved surface being about 5/8 to 1 1/4 inch in radius.
Claim 5
Independent Claim
197 words
An apparatus for reducing fluid flow from inlet and outlet ports in an enclosure through which a threadline passes in a substantially straight path for treatment in a fluid stream that is exhausted from the enclosure, said apparatus comprising: an enclosure forming a chamber having upper, lower, front and backwalls, there being an exhaust port in communication with the chamber through the lower portion of the backwall and aligned inlet and outlet ports through the upper and lower walls respectively for passage of the threadline to and from a jet device mounted on said backwall, said jet device having a stream-forming orifice and an opposed plate positioned on opposite sides of said path, the central axis of the orifice being perpendicular to said path, said plate having a surface in a plane perpendicular to said central axis; means connected to said exhaust port for maintaining a pressure less than ambient in said chamber; means for supplying pressurized fluid to said jet device, said jet device having a surface with a curvature of about 5/8 -inch radius adjacent said orifice, said surface sloping gradually upwardly and away from the threadline to substantially meet and terminate at the backwall.
Claim 6
Independent Claim
197 words
An apparatus for reducing fluid flow from inlet and outlet ports in an enclosure through which a threadline passes in a substantially straight path for treatment in a fluid stream that is exhausted from the enclosure, said apparatus comprising: an enclosure forming a chamber having upper, lower, front and backwalls, there being an exhaust port in communication with the chamber through the lower portion of the backwall and aligned inlet and outlet ports through the upper and lower walls respectively for passage of the threadline to and from a jet device mounted on said backwall, said jet device having a stream-forming orifice and an opposed plate positioned on opposite sides of said path, the central axis of the orifice being perpendicular to said path, said plate having a surface in a plane perpendicular to said central axis; means connected to said exhaust port for maintaining a pressure less than ambient in said chamber; means for supplying pressurized fluid to said jet device, said jet device having a surface with a curvature of about 5/8 -inch radius adjacent said orifice, said surface sloping gradually upwardly and away from the threadline to substantially meet and terminate at the backwall.
