Patent number: 11007687Abstract: A system and method to dispense, mix, and inject liquids and force them into a vented investment pattern mold cavity comprises a source of raw materials in fluid communication with an injection unit for metering and delivering the raw materials. A mixing and injection head receives and mixes the metered raw materials. A movable molding cart upon which an investment pattern mold is mounted is disposed adjacent the injection unit and proximate the mixing and injection head. The movable molding cart includes a fill cup that may be engaged by the mixing and injection head. A displaceable gating tray provides fluid communication with the fill cup and a sprue aligned with an investment port on a lower portion of the investment pattern mold. The system also includes a digital computer control by which the injection process may be controlled.Type: GrantFiled: September 28, 2018Date of Patent: May 18, 2021Assignee: LEGACY FOAM LLCInventor: Bruce M.

Patent number: 9102558Abstract: A transportable water treatment system includes: a lower cage housing a water purifying apparatus, a middle cage housing a first water storage tank, and an upper cage housing a second water storage tank. The transportable water treatment system has a footprint approximate to the area of the lower cage. A chlorinator may be used in the water purifying apparatus that includes a bowl having an inlet at the bottom and an outlet on its side. A channel is around the inlet forcing fluid to flow to the top of the channel and over its edges. A flow diverter is positioned above the inlet adapted to transfer the flow of fluid to a substantially horizontal direction. A platform is positioned within the channel being adapted to position a single chlorine tablet within the channel. The lid is adapted for holding a plurality of chlorine tablets above the platform.Type: GrantFiled: April 4, 2013Date of Patent: August 11, 2015Assignee: Water Missions InternationalInventors: George C. Greene, III, Bruce M. Okkema

Patent number: 8905055Abstract: A full flow pressure relief valve includes a housing having an inlet opening on its bottom and an outlet opening on one of its side. A piston is positioned inside the housing adapted to move from a set position where the piston seals the inlet opening to a sprung position where the piston is removed from the inlet opening. A lock is biased by a spring in a perpendicular direction toward the side of the piston. The lock is adapted to hold the piston in the set position until a relief pressure is supplied in the inlet opening, where the lock is adapted to release the piston to the sprung position.Type: GrantFiled: April 14, 2011Date of Patent: December 9, 2014Assignee: Water Missions InternationalInventors: George C. Greene, III, Bruce M. Okkema

Publication number: 20110272351Abstract: A chlorinator for a biosand filter includes a chlorinator adapted for treating water after it has been filtered by a biosand filter. The chlorinator has a housing having an inlet on a side and an outlet on a bottom. The inlet is adapted to be attached to the outlet of a biosand filter. A dividing partition divides the housing into an inlet section, an outlet section and a chlorinator section. The inlet section is in fluid communication with the inlet, the chlorinator section and the outlet section. The chlorinator section is in fluid communication with the inlet section and the outlet section. The outlet section is in communication with the outlet. A flow control mechanism in the inlet section is adapted to adjust the amount of water flowing through the chlorinator section.Type: ApplicationFiled: March 15, 2011Publication date: November 10, 2011Inventors: George C.

Publication number: 20100017948Abstract: A dual flush valve includes an outflow pipe, a lower seal, and an upwardly extending guide. A lower flush valve reciprocates on the guide between a lowered position sealing the lower seal and a full volume flush position unsealing the lower seal with respect to the outflow pipe. An upper flush valve reciprocates on the guide between a lower sealed position sealing the upper seal with respect to the lower flush valve, an intermediate partial volume flush position unsealing the upper seal and a higher full volume flush position unsealing the lower seal. An interconnecting lost motion member allows movement of the upper valve between the lower sealed position and the partial volume flush position without disturbing the lower valve, while transmitting additional upward movement of the upper valve to the lower valve to move the lower valve between the lowered position and the full volume flush position.Type: ApplicationFiled: July 22, 2008Publication date: January 28, 2010Applicant: SELECTAFLUSH LLCInventors: David William Bauer, Bruce M.
