The present invention is directed to an apparatus and process for precisely measuring the position of a deflector blade. When patterned dyeing a moving textile web wherein continuously flowing streams of liquid normally directed in paths to impinge upon the web are selectively deflected from contact with the web in accordance with pattern information then each continuously flowing liquid stream is selectively deflected by a stream of air which is discharged, in accordance with pattern information, from an air outlet located adjacent each liquid discharge outlet. The air outlet is positioned to direct the air stream into intersecting relation with the liquid stream and to deflect the liquid into a collection chamber or trough for recirculation. To accurately control the amount of dye applied to a given location on the material during the dyeing operation, and to insure that the dye strikes the material in a very small, precise spot, the lower portion of the collection chamber contains a deflector blade supportably positioned in spaced relation above the lower wall of the collection chamber and wherein means are provided for accurately measuring the position of the deflector blade to facilitate accurate placement of the dye streams on the moving material during the printing process and precise interception of the streams when deflected.

Method and apparatus for measuring the position of a dye deflector blade

An apparatus to cause a running length of yarn to vibrate at its harmonic frequency by through utilization of dual orifices through which pressurized air flows at an angle of intersection and to measure electronically the harmonic frequency thereof to provide a signal that can be employed to maintain and/or correct the parameters of the system to maintain a desired tension in the yarn being run.
