Patent number: 9383518Abstract: An optical switch having a housing, a light source and a light detector. The light source and light detector are located remote from the housing. The light source is connected to the housing with a first light guide, and the light detector is connected to the housing with a second light guide. The first and second light guides have distal ends coupled to the activation, and a part of the activator housing or movable member is a glowable diffuse reflector. The switch moveable member moves in a path in the switch body between an optical path present state and an optical path absent state.Type: GrantFiled: December 14, 2012Date of Patent: July 5, 2016Inventors: Christopher E.

Patent number: 7223343Abstract: A reactor chamber for placement in a wastewater treatment system, where the reactor chamber has a chamber formed from a sidewall which forms an interior of the chamber. The sidewall has a top portion and a bottom portion and fixed channel growth media positioned in the interior of the chamber. The fixed channel growth media is positioned below the top of the sidewall, so that when positioned in a treatment system, most of the growth media is located below the water level in the treatment system. The top of the sidewall near the water level (when positioned in a treatment system) is substantially impermeable to wastewater. The reactor includes an air distribution manifold system having a series of air release sites positioned below the fixed channel growth media and adapted to release air which disperses upwardly through the fixed channel growth media. Influent is discharged into the treatment tank near the air discharge sites.Type: GrantFiled: February 22, 2005Date of Patent: May 29, 2007Assignee: Pentair Pump Group, Inc.Inventors: Raleigh L. Cox, Christopher E. Cox, Brenda Guy, Michael D. Catanzaro, Murphy M. Arcemont, III, Travis L. LeJeune

Patent number: 7014769Abstract: The present invention is a method for reducing the nitrate concentration in wastewater within a wastewater treatment apparatus configured to define an aeration zone and a quiescent zone or dilution zone. The method comprises the step of ceasing airflow into the aeration zone for a predetermined time period or until the dissolved oxygen level within the wastewater has reached a predetermined threshold. The method also comprise the step of mixing the wastewater in the aeration zone to prevent suspended particles within the wastewater in the aeration zone from settling and to avoid substantially disturbing the quiescence of the quiescent zone.Type: GrantFiled: June 8, 2004Date of Patent: March 21, 2006Assignee: Pentair Pump Group, Inc.Inventors: Raleigh L. Cox, Christopher E. Cox, Brenda Guy, Michael D. Catanzaro, Murphy M. Arcemont, III, Travis L. LeJeune
