Abstract: The invention is a control valve for a nebulizer for inhalation therapy which stops the supply of mist except when the patient is actually inhaling. The preferred structure is a "T" shaped configuration with the lower end mounted atop the nebulizer and one end of the horizontal breath tube used as a mouthpiece. A shuttle cylinder with a check valve slides axially within the breath tube and includes a hole which aligns with the feed tube when the shuttle is at the end toward the patient. In that position the shuttle permits the mist to reach the patient through the shuttle. However, when the patient exhales, the shuttle moves to the opposite end of its travel and closes off the supply of mist while permitting the exhaled air to exit.

Abstract: A hair curling appliance includes two hair curling wands and a base assembly for heating the wands to a desired temperature. The base assembly includes two overlapping plate-like retention members having trough-like end portions which coact to form sockets for receiving the wands, and center portions which coact to form a cavity for holding an electrical heating element. The wands include hair retaining clamps operable from the handles of the wands, and heat insulating end caps which reduce the possibility of a user coming into accidental contact with the heat transfer portions of the wands.
