Publication number: 20220211476Abstract: An apparatus and method for removing amalgam and waste particles from dental office suction effluent. The apparatus includes an upper chamber and a solids collection canister removably secured thereto. Dental office suction effluent drawn through a dental suction wand enters the upper chamber along a lateral flow path above a substantially cylindrical internal wall portion. A gas component of dental office suction effluent changes direction by more than 60° before it exits the upper chamber through an exit port. A riser conveys a liquid and solids component of dental office suction effluent through a drain into the solids collection canister. A flow restrictor allows liquids and gases to exit the solids collection canister interior volume but prohibits solids from exiting the solids collection canister interior volume.Type: ApplicationFiled: March 22, 2022Publication date: July 7, 2022Inventors: Douglas S. Stolarik, Douglas M. Homer, Michael P. Mormino, Owen E. Boyd

Patent number: 10183245Abstract: A water filtration system utilizes a housing configured to utilize various types of filter media and having a press-sealed closing system. The closing system includes a head portion defining a head opening, a lock member, and a lid member. The lock member releasably engages the head portion such that an abutment section of the lock member projects into the head opening. The lid member is received by the head portion to cover the head opening, and has an outward-facing press section configured to abut an inward facing portion of the abutment section of the lock member when the lid member is covering the head opening. Pressure generated within the housing during water filtration presses the lid member in an outward direction and causes the lid member press section to press against the abutment section of the lock member to substantially prevent disengagement of the lock member from the head portion.Type: GrantFiled: July 25, 2017Date of Patent: January 22, 2019Assignee: ENPRESS L.L.C.Inventors: Douglas M.

Patent number: 8382994Abstract: The present invention provides a composite pressure vessel containing a distributor plate. The distributor plate comprises a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening. The disk is provided with a plurality of radial slits, which define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side such that it swirls around the central opening. The perimeter edge of the distributor plate is joined to an inner side of a thermoplastic liner during or immediately after the thermoplastic liner is formed by a blow-molding process or a rotational molding process.Type: GrantFiled: December 31, 2009Date of Patent: February 26, 2013Assignee: Enpress LLCInventors: Douglas S.

Patent number: 8110103Abstract: The present invention provides a flow-control support for a distributor plate in a composite pressure vessel. The distributor plate includes a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening and a plurality of fluid flow passages through the disk. The flow-control support is disposed between the bottom side of the disk and an inner side of an end of a thermoplastic liner assembly. The flow-control support includes a spirally fluted upper surface that is adapted to direct fluid flowing from a supply pipe disposed in the central opening of a distributor plate that is supported by the flow control support such that the fluid swirls in a space between the bottom side of the distributor plate and an inner side of an end portion of a water treatment vessel. The swirling water insures that fluid is distributed to substantially all of the fluid flow passages through the disk during backwashing operations.Type: GrantFiled: March 5, 2009Date of Patent: February 7, 2012Assignee: Enpress LLCInventors: Michael P.
