Abstract: A hand control device for swimmers is presented. The device has a main body with two holes in a side-by-side configuration. The first one of the two holes is configured for a third digit of a person's hand while the second one of the two holes is configured for a fourth digit of the person's hand. The inside surface of each hole comprises a plurality of grooves that run depthwise thereby providing wet traction while impacting minimum direct pressure on the nerves, vessels and tendons. The outside surface of the device may also include ridges to provide pass through for water.

Abstract: A dual chambered bubbler vessel for use with solid organometallic source material for chemical vapor phase deposition systems, and a method for transporting a carrier gas saturated with source material for delivery into such systems. The bubbler vessel is designed so that carrier gas enters through an inlet in the top thereof into an inlet chamber and after it has been saturated with the organometallic vapors exits through a first porous frit located in the floor of the inlet chamber into an outlet chamber and is withdrawn from the bubbler after passing through a second porous frit element located at the outlet of the bubbler.
