Abstract: A method of decorating a fabric in which an elongate strip of fabric is sewed to a base fabric along a line spaced inwardly from the edge of the strip of fabric. The base fabric with strips sewed thereto is then washed in a washing machine so as to cause the edges of the strips of fabric outside of the line of stitching to fray and to thus take on a decorative appearance. The invention also includes the fabric produced by this method with the strips of material being arranged in any desired decorative pattern on the base material.

Abstract: A nebulizer for uniformly tempering and humidifying oxygen and different predetermined mixtures of oxygen-enriched air comprising a vessel containing a volume of water, oxygen supply means delivering oxygen into the vessel, air supply means conducting air into the vessel, and electric resistance heater means to heat the water in the vessel, said air supply and heater means including adjustable air metering means with a movable control part and said electric heater means including an adjustable control unit with a movable part, drive means connected with and between said movable parts whereby movement of one of said control parts results in predetermined corresponding movement of the other control part, whereby changes in the volume of air conducted into the vessel by said metering means results in predetermined corresponding heat output by the metering means and resulting tempering of the water.
