Abstract: A fluid dispenser having a fluid container, a spout, and a pump for pumping fluid from the container out to the spout and having a piston for moving vertically along a piston axis. The spout has an inner end connected to the piston through a piston cap, with downward pressure on the piston cap moving the piston downward and actuating the pump. The spout also has a center section, an outer end with an outer bend, and an inner end with an inner bend, the piston has an upper end, and the spout inner end and the piston upper end have interengaging threaded portions coaxial with the piston axis. The piston cap has a body with a central opening coaxial with the piston axis and a lateral opening connecting with the central opening for receiving the spout, with the piston cap rotatable with the spout as the spout inner end is threaded into the piston upper end.

Abstract: A method and apparatus is disclosed for separating finely sized materials of diverse weights comprising a housing 8 having an opening 20 through which materials may be introduced for separation, an air intake 26 through which air may be introduced, and an air outlet 34 through which an air stream may exit. Means 53 are provided for forcing air into the housing 8 through the air intake 26 and out of said housing through the air outlet 34. A series of steps 10, 12, 14 is mounted within the housing 8 over which the materials may cascade. Means are further provided for channeling air introduced into the housing 8 through the air intake 26 into at least one air stream which passes between adjacent steps of the series of steps whereby the air stream may pass through the cascading materials and entrain the lighter materials.
