| 20150083234 | Pressure Vessel System and Method - Diaphragm joint and convolutions, bottom screen diffuser, air stern, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel. | 03-26-2015 |

| 20090078323 | Air discharge device - My inventive property is a tool to expel residual liquid from larger diameter hose, pipe or any other defined tubular conduit such as Fire Hose or Lay Flat PVC Hose, therefore dramatically reducing the weight of said conduit prior to retrieval and defined storage. All prior art fails to solve problems with reducing the time and labor required to remove residual liquid from said conduit without lifting the entire length to a point above the end (“Walking Out”) so gravity can remove residual liquid or by using a roller on the entire length of said conduit. My inventive property is comprised of five essential parts; a Gas Containment Vessel, a Safety Relief Valve, a Gas Fill Valve, a Gas Outlet Control Valve and a Final Stage Outlet Conduit Connection Adaptor. | 03-26-2009 |
| 20100263738 | Pressure Equalization Assembly for a Liquid Storage Vessel - A vapor pressure equalization assembly having an underpressure relief assembly and an overpressure relief assembly in fluidic communication with the vapor space of a liquid storage tank (vessel). The underpressure and overpressure relief assemblies each have movable pistons sealingly engageable with respective sealing members, and biasing members which exert respective biasing forces to maintain the pistons in sealing engagement with the sealing members. A predetermined underpressure or overpressure differential between the vapor space pressure and atmospheric pressure will cause one of the pistons to open fluidic communication of the vapor space to equalize the vapor space pressure with that of the surrounding atmospheric pressure. | 10-21-2010 |
| 20120037243 | Pressure Equalization Assembly for a Storage Vessel - Apparatus for equalizing pressure within a vapor space of a storage vessel. In accordance with various embodiments, a pressure equalization assembly has a base housing member adapted to be mounted to a tank adjacent a tank aperture in fluidic communication with a vapor space of the tank. A canister assembly is adapted for removable engagement with the housing member between a closed position and an open position. The closed position establishes a fluidic seal interface between the housing member and the canister assembly. The open position provides user access to the vapor space through the tank aperture. The canister assembly further has a compound seal assembly with first and second pistons biased against corresponding first and second annular seal members while the canister assembly is in both the closed position and the open position. A third annular seal member is disposed between the canister assembly and the base housing member. | 02-16-2012 |
