Abstract
Abstract Successive sections of a strand material are advanced along a predetermined path into an entrance end of, through, and then out of a laterally closed chamber. The entrance end of the chamber is in communication with the air of the ambient atmosphere. High velocity jet streams of treating material are directed into the chamber toward oblique converging engagement with the successive sections of the strand material. Substantial components of the velocities of the jet streams are in the direction of travel of the strand material. The minimum cross-sectional area of the passages of the chamber through which the streams are directed and the strand material travels are substantially greater than that of the strand material. The velocity of the jet streams and the geometrical relationship of passages of the chamber through which the strand material and the jet streams pass and the pressure of the air are such as to create pressure differentials sufficient to cause air to be drawn into the entrance of the chamber at a volumetric flow which is substantially greater than that of the treating material. The air is mixed with the treating material to produce a vapor mixture which moves through the chamber along the path of the strand material to treat the strand material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
300 words
An apparatus for treating elongated material, which comprises: a laterally enclosed chamber having an entrance end and an exit end, an upstream portion of the chamber communicating with a fluid material capable of being in a gaseous state; means for causing relative movement between the laterally closed chamber and successive sections of an elongated material along a predetermined path; and means for directing at least one high velocity jet stream of a treating material into the chamber downstream from the portion of the chamber communicating with the fluid material; the direction of the jet stream being such that a substantial component of the velocity of the jet stream is in the direction of travel of the successive sections of the elongated material; the minimum cross-sectional area of portions of the chamber through which the stream is directed and the successive sectionS of the elongated material extend being substantially greater than the cross-sectional area of the elongated material; the velocity of the jet stream of treating material and the geometrical relationship of the cross-sectional areas of the portions of the chamber through which the successive sections of the elongated material extend and the jet stream passes and the pressure of the fluid material in direct communication with the upstream portion of the chamber being such as to create a pressure differential sufficient to cause portions of the fluid material in direct communication with the upstream portion of the chamber to be drawn into the chamber in a gaseous state at a volume of flow per unit time which is substantially greater than the volume of flow of the treating material per unit time to mix with the treating material and produce a vapor mixture which moves through the chamber along the path of the elongated material to treat the elongated material.
Claim 2
Independent Claim
300 words
An apparatus for treating elongated material, which comprises: a laterally enclosed chamber having an entrance end and an exit end, an upstream portion of the chamber communicating with a fluid material capable of being in a gaseous state; means for causing relative movement between the laterally closed chamber and successive sections of an elongated material along a predetermined path; and means for directing at least one high velocity jet stream of a treating material into the chamber downstream from the portion of the chamber communicating with the fluid material; the direction of the jet stream being such that a substantial component of the velocity of the jet stream is in the direction of travel of the successive sections of the elongated material; the minimum cross-sectional area of portions of the chamber through which the stream is directed and the successive sectionS of the elongated material extend being substantially greater than the cross-sectional area of the elongated material; the velocity of the jet stream of treating material and the geometrical relationship of the cross-sectional areas of the portions of the chamber through which the successive sections of the elongated material extend and the jet stream passes and the pressure of the fluid material in direct communication with the upstream portion of the chamber being such as to create a pressure differential sufficient to cause portions of the fluid material in direct communication with the upstream portion of the chamber to be drawn into the chamber in a gaseous state at a volume of flow per unit time which is substantially greater than the volume of flow of the treating material per unit time to mix with the treating material and produce a vapor mixture which moves through the chamber along the path of the elongated material to treat the elongated material.
