Abstract: There is provided a self-watering apparatus for growing plants comprising a soil retaining compartment and a first and second water reservoir compartments, the first reservoir compartment being of substantially lesser cross-sectional area than the second. The second water reservoir compartment is open to the atmosphere and by virtue of an interconnection between the first and second reservoirs, maintains the water level in the first. The apparatus provides three zones through which a root grows, a soil zone, an air zone and a water zone, which air zone is maintained at high humidity by virtue of the small cross-sectional area of the first water reservoir zone, which prevents injury to roots growing into the water zone and encourages root growth toward the water zone.

Abstract: A personal audio listening system to be worn by an individual listener is disclosed and includes a pair of speakers mounted within a flexible supporting body which surrounds the back and side portions of the listener's neck. The supporting body may include portions which extend generally forward from both sides of the listener's neck and may be joined by a safety releasable fastener to form a closed loop around the listener's neck. The supporting body includes acoustical and safety padding, speaker grills for protecting the speaker cones and the necessary electrical connections for coupling to an audio signal source. The audio signal source may be external to the supporting body or may be enclosed within the supporting body.

Abstract: Disclosed is a novel nozzle assembly adapted to pass fluid, by means of a fluid outlet line, into any one of a plurality of tank lines, each of the tank lines defining a tank line port. The nozzle assembly is further adapted to receive vapors passing through the tank line port from any one of the tank lines.
