Patent number: 10105643Abstract: A hydrogen gas dryer or system for drying or removing water from hydrogen gas for use in hydrogen-cooled generators includes a drying tower or column comprising a housing, a heater, a desiccant, and a controller. The system is configurable and operable for regeneration of the saturated column, with activation of the heater to cause water retained in the saturated desiccant to turn into steam such as steam and exit on its own via the vent. A supply of generally dry hydrogen is used to purge the remaining vaporized water from the isolated substantially dry regenerated desiccant.Type: GrantFiled: May 16, 2018Date of Patent: October 23, 2018Assignee: Environment One CorporationInventors: Robert A. Williams, Ronald F. Brosnihan

Patent number: 8678303Abstract: A method for operating a grinder pump station and inhibiting the likelihood of operation of a grinder pump assembly under at least one of a run dry condition and a blocked condition includes providing a wattmeter circuit operably connected to the grinder pump assembly and measuring real power using the wattmeter circuit during operation of the grinder pump assembly to process sewage received in a tank and discharge the processed sewage from the tank. The grinder pump assembly is automatically turned off based on the real power (e.g., average value of the product of instantaneous values of voltage and current over time) measured by the wattmeter circuit due to the at least one of a run dry condition and a blocked condition.Type: GrantFiled: May 14, 2008Date of Patent: March 25, 2014Assignee: Environment One CorporationInventor: David Capano

Patent number: 8297466Abstract: A sewage tank for use with a pump such as a grinder pump to convey sewage. The sewage tank includes a container having an upper portion and a lower tapering portion defining a chamber for containing the pump. The lower tapering portion has a reduced size compared to the upper portion. The upper portion and the lower portion may include a plurality of intersecting vertical ribs and horizontal ribs defining a plurality of recessed pockets. The lower portion of the sewage tank may also include an outwardly-extending flange sufficiently sized so that soil may be backfilled around the bottom of the tank to prevent the tank from floating upward out of the ground due to its buoyancy under high ground water conditions. The sewage tank may also include a stepped flange.Type: GrantFiled: November 19, 2009Date of Patent: October 30, 2012Assignee: Environment One CorporationInventors: Paul J. Daley, Clark A. Henry, Adrian Massey

Patent number: 8074911Abstract: A liquid level sensing assembly employs an inductive or magnetic coupling to wirelessly communicate a plurality of signals based on a changing level of wastewater in a tank to a first coil of a pump/alarm control circuit in the grinder pump. The assembly includes at least one liquid level sensor operable in response to the changing level of the wastewater, a second coil positionable adjacent to the first coil in the grinder pump, and a transponder for extracting electrical energy using the second coil in response to the first coil. The transponder is operably connected to the at least one liquid level sensor and operable to wirelessly transmit from the second coil to the first coil the plurality of signals based on the state of the at least one liquid level sensor due to the changing level of the wastewater in the tank.Type: GrantFiled: May 14, 2007Date of Patent: December 13, 2011Assignee: Environment One CorporationInventors: David Capano, Clark A.

Patent number: 7802741Abstract: A pump assembly supportable in a tank having an opening includes a pump such as a grinder pump and a cover attachable to the pump. The cover has a peripherally-extending portion extending outwardly from the pump and the peripherally-extending portion is sized to rest on a first surface of the portion of the tank defining the opening. A quick-release latching mechanism may include a plurality of members such as arms or pawls which are movable generally radially between a retracted position wherein the outer ends of the plurality of members are disposed inwardly of the peripherally-extending portion of the cover allowing the pump assembly to be lowered into the opening in the tank, and an extended position wherein the outer ends of a plurality of members are positionable against a second opposite side of the portion of the tank defining the opening to compress the portion of the tank forming the opening between the cover and the plurality of members.Type: GrantFiled: May 14, 2008Date of Patent: September 28, 2010Assignee: Environment One CorporationInventors: Kurt Werner, David Fergot, David T.
