Appl. No.:

10/093690

Inventors:

International Classification:

C02F 1114

US Classification:

210710, 210732, 210747, 210770, 405 52, 37318

Abstract:

A method and apparatus for remediating wastewater holding areas and the like includes a closed, foraminous dewatering membrane that is positioned adjacent to the wastewater holding area. Sludge and adjacent water on the bottom of the wastewater holding area are pumped in the form of a sludge slurry into the interior of the dewatering membrane. The water is removed from the sludge slurry by allowing gravitational forces to flow water through the dewatering membrane. The dewatering membrane is then opened, and the dewatered sludge is removed for depositing at an appropriate site.

International Classification:

C07C 29/74

US Classification:

568917

Abstract:

The present invention is directed to processes for producing a high purity organic solvent from a crude organic solvent comprising providing a stream of crude organic solvent comprising a first amount of at least one impurity and adsorbing at least one impurity contained in said crude organic solvent onto an adsorbent to produce a purified organic solvent comprising a second amount of impurities, the second amount of impurities being less than the first amount of impurities.

Appl. No.:

10/911909

Inventors:

Russell Johnson - Wayland MI, US

International Classification:

E01C 11/14

US Classification:

404060000

Abstract:

A starting gate for bikes including a support structure and a gate member movably mounted to the support structure for movement between raised and lowered positions. The starting gate includes a retaining member configured to selectively retain the gate member in the raised position. A pedal is operably coupled to the gate member such that depression of the pedal raises the gate member to the raised position. The starting gate further includes a timer configured to shift the retaining member to release the gate member such that the gate member moves to the lowered position after a predetermined period of time after depression of the pedal.
