  • Fabric softening apparatus
    Patent number: 4837902
    Abstract: An apparatus and method of treating fabric by directing low pressure air at near-sonic velocity between the fabric and a rigid plate tangentially in the warp direction of the fabric to cause the fabric to vibrate at an extremely high rate. This high speed vibration causes sawtooth waves in the fabric to break fiber-to-fiber resin or finish bonds thereby decreasing the bending and shear stiffness to enhance the flexibiity, drape and softness of the fabric.

  • Method and apparatus for interrupting fluid streams
    Patent number: 4828174
    Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target.
