Publication number: 20100230333Abstract: The amount of sealant needed as an odor barrier in a wastewater cartridge is reduced. The cartridge inlet compartment (78) has a ceiling (90) of given area. The ceiling is spaced from the cartridge upper wall (60) and from the wastewater-receiving opening (64) therein. A throat (88), which communicates the inlet compartment with the wastewater-receiving opening, has an area which is less than the area of the ceiling, so that the amount of the sealant acting as the barrier, as contained within the throat, is less than any further amount of the sealant (under the ceiling) which floats on the wastewater in the inlet compartment. Also, should sealant not be present within the throat to act as an odor barrier, only a small area of wastewater present within the throat would be exposed to the air external to the cartridge and, thus, present a lesser opportunity of odor to emanate to the outside environment.Type: ApplicationFiled: March 9, 2010Publication date: September 16, 2010Applicant: Falcon Waterfree TechnologiesInventor: Robert Avetisian

Publication number: 20090090673Abstract: A system and method for remediating a body of water and collecting suspended and dissolved solids therefrom are provided. The system includes a water-impervious lining positionable in a depression in or adjacent a body of water. The lining and depression define a treatment vessel, which includes a treatment portion, an outlet portion for containing treated water, and an outflow weir between the treatment portion and the outlet portion. Water to be treated is transported from the water body to the treatment portion. An entrapment element is delivered and mixed into the transported water, the entrapment element for capturing suspended and dissolved solids in the transported water and effecting a separation between the captured solids and water cleansed therefrom. The captured solids can be removed from the treatment basin, and the cleansed water can move through a channel in the outflow weir into the outlet portion.Type: ApplicationFiled: July 31, 2008Publication date: April 9, 2009Applicant: AQUAFIBER TECHNOLOGIES CORPORATIONInventors: Kyle R.

Patent number: 7513991Abstract: A clogging indicator for a fish tank or aquarium comprising a transparent vertical tube with a float positioned therein. The indicator is designed to sit on the outside of the tank and the filter itself. The water level in the tube is lowered and raised according to the amount of water with a rear chamber of the filter. Indicating marks are located on the tube to visually display normal or clogged operation. Backup water from a clogged filter will raise the water level in the rear chamber and thus also the indicator tube. As the water level rises, the float raises toward a warning indicator mark to indicate the need for filter changing.Type: GrantFiled: August 24, 2005Date of Patent: April 7, 2009Assignee: J.W. Pet Company, Inc.Inventor: Jonathan Willinger

Patent number: 7470371Abstract: A platelet collection device comprising a centrifugal spin-separator container with a cavity having a longitudinal inner surface. A float in the cavity has a base, a platelet collection surface above the base, an outer surface. The float density is below the density of erythrocytes and above the density of plasma. The platelet collection surface has a position on the float which places it below the level of platelets when the float is suspended in separated blood. During centrifugation, a layer of platelets or buffy coat collects closely adjacent the platelet collection surface. Platelets are then removed from the platelet collection surface. Movement of a float having a density greater than whole blood through the sedimenting erythrocytes releases entrapped platelets, increasing the platelet yield.Type: GrantFiled: October 19, 2006Date of Patent: December 30, 2008Assignee: Hanuman LLCInventors: Randel Dorian, Scott R. King, Richard Wood Storrs

Patent number: 7468128Abstract: A fluid pollution prevention system for preventing the discharge of hazardous waste from a bilge of a marine vessel. The system includes an continuous sidewall that defines a vertically enclosed volume. When positioned within a bilge, the sidewall forms a barrier to petrochemicals floating on a fluid surface within the bilge. An opening near a base of the sidewall permits fluid from beneath the fluid surface to enter the vertically enclosed volume. Such fluid is substantially free of petrochemicals and may be removed form the vertically enclosed volume. Accordingly, by pumping fluid out of the enclosed volume, fluid may be removed form the bilge substantially free of petrochemicals. In one arrangement, the vertically enclosed volume may be sized to receive a bilge pump.Type: GrantFiled: December 16, 2005Date of Patent: December 23, 2008Assignee: Paul Arthur ClukiesInventor: Paul Arthur Clukies

Patent number: 7429319Abstract: The present invention discloses a sewage slurry separation system adapted to assist in sewer cleaning operations. The sewage slurry separation system is configured for collecting sewage slurry from a sewer line, depositing the sewage slurry in a collection/settling chamber to separate the slurry into water and sludge. The water is then pumped back into the sewer line. The system includes a sewage collection tank with a compacting plate. The compacting plate divides the sewage collection tank into a sewage collection chamber and a water collection chamber. The compacting plate has a passage that allows water from the sewage collection chamber to flow into the water collection chamber. The sewage slurry separation system also includes a submersible pump connected to the sewage collection chamber. The submersible pump pumps sewage slurry into the sewage collection chamber.Type: GrantFiled: July 26, 2006Date of Patent: September 30, 2008Inventor: Rufus Davis

Patent number: 7387722Abstract: An automatic system for treating water, which consists of two treatment tanks adapted to be operated alternately. The tanks are interconnected with each other by a unique isolation valving system that permits one tank to be in use while the other is on standby. They are also connected to a single brine tank and alternate by being controlled with a novel, photo/electric water sensor, which reacts to a predetermined flow of water through the tanks. This system is very environmentally friendly by reducing the amount of water and salt used in the regeneration of the minerals compared with other systems operating today.Type: GrantFiled: January 24, 2005Date of Patent: June 17, 2008Inventors: Robert G Varner, Daniel G.
