Abstract: A tool for use with a locking mechanism of an instrument setup of a stringed musical instrument comprises a body having a longitudinal axis, a transverse axis, a first surface extending along the longitudinal axis, and a second surface substantially parallel to the first surface of the body. The tool also includes a key disposed on the first surface and extending substantially along the transverse axis and a magnet disposed on the second surface of the body is configured for being received within a socketed head of the locking mechanism of the instrument setup system. The magnet is configured to be attached to a magnetic surface on the stringed instrument to hold the tool in place during use for “one handed” operation.

Abstract: A pump has flexible vanes arranged in a helical path in the clearance between the stator and the rotor. In one form, the helically wound vanes are present on the rotor, the stator including at least one can surface to flex the vanes. In another form, the helically wound vanes are present on the stator, the rotor including at least one can surface to flex the vanes.

Abstract: Photosynthetic organisms are grown in a tube having a gas inlet at one end and a gas outlet at the other. The tube containing a rotor having vanes adapted to wipe the inside surface, the tube being disposed at an angle to the horizontal in a bath containing liquid, the gas inlet being lowermost.
