  • Patent number: 8646117
    Abstract: To reduce the barrier sealant amount, the area of a throat (88), communicating an inlet compartment (78) to an outlet opening (64), is made small. Should sealant not be in the throat, wastewater in the throat would be correspondingly small. A snorkel (110) in a discharge section drain tube (98) extends downwards to above the level of the horizontal drain, and allows any air from the external drain to pass to the outlet compartment generally below the ceiling (90) so that, should wastewater cover the opening of the drain tube, such air is permitted to enter into the cartridge and to prevent any syphoning. A three rib channel guide mechanism (100) within the tube guides wastewater flow towards the drain tube center, and away from the drain tube walls to avoid deposit of any sediment contained in the wastewater.

  • Publication number: 20130333763
    Abstract: An access system for a pressure controlled environment is disclosed and described. The system can include a pressurized region having a first fluid. The pressurized region can be defined, at least partially, by a barrier separating the pressurized region from a lower pressure region. The system can also include a trap fluidly coupling the pressurized region and the lower pressure region through at least a portion of the barrier. The trap can have a second fluid forming a seal to prevent the first fluid from escaping the pressurized region. Additionally, the system can include at least one cable extending through the trap and the barrier into the pressurized region.

  • Publication number: 20130284282
    Abstract: An in-line water trap located in the line of the flow of waste through a generally straight line or bend is provided for. Typically, the water trap comprises a fluid conduit having a first end, a second end and a passage between the first and second ends; and a vessel having a closed end, an open end and a skirt between the closed and open ends, the lobed vessel further having an inner surface defining an inner volume and an outer surface, the inner surface attachingly engaging an outer wall of the fluid conduit in so doing defining a flow path between the passage, the inner volume of the lobed vessel and the outer surface of the lobed vessel, in use, a fluid level inside the inner volume of the lobed vessel being substantially in communication with the second end of the fluid conduit to form a fluid seal.

  • Patent number: 8485216
    Abstract: In a urine cartridge or wastewater trap, equalized pressures and increased flow rate between its inlet and outlet compartments increases the life of the cartridge. The pressure equalizing is effected by placement of a separator between the two compartments to provide them with substantially equal volumes. The increased flow rate is created by a uniquely configured baffle positioned adjacent a pan at the bottom of the cartridge. The baffle configuration is shaped to provide a constriction that increases the flow velocity of the urine so that the fluid flow effects a channel along the bottom pan and through any solids deposited on the bottom pan. A diverter may be placed above the centrally located entry to the inlet compartment to create a circuitous path for preventing a disturbing impingement of the urine onto the sealant contained in the inlet compartment.

  • Patent number: 8382993
    Abstract: A removable drain filter apparatus (20) with an housing (22) connectable with upstream and downstream drain pipes (40, 46) has a filtering chamber wider than the drain pipes and divided into an upstream portion (78) and a downstream portion (82) by a generally planer filter element (50). A hatch cover (32) carries a downwardly extending central core (76) with an O-ring seal (84), a filter securement member (86) for pressing the filter element (50) against an underlying support ledge (29) and a drain hole plug (88). The location of the O-ring (84) relative to the filter element (50) and the plug (88) being tapered enables the filter housing (22) to be drained of any water during removal of the hatch cover and before the watertight seal is broken to eliminate leakage of drain water out of the housing (22) when the hatch (31) is completely opened. The filter (50) bends out of the way of a plumber's auger (96).

  • Publication number: 20110174289
    Abstract: A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.

  • Patent number: 7854238
    Abstract: The present invention provides a conduit trap, which can also operate as condensation recovery device when installed in a refrigeration system drainage line. The conduit trap is generally a hollow body defining a fluid path that includes an upper conduit 20, having a waste outlet 30 and optionally a condensation collection outlet 32. A lower conduit 22 extends downwardly from the upper conduit and has a narrowing that creates an inner sealing region for receiving a sealing means, such as float 50. Condensation can be directed from the refrigeration system through the conduit trap for recovery or for disposal without exposing the refrigeration drainage line and occupied space in which the refrigeration unit is located to sewer gasses even in dry weather when a gravity based, fluid-filled trap would fail.

  • Patent number: 7575022
    Abstract: A diverter (170, 270) atop the upper wall (110) of a cartridge (100) and over the opening (114, 115) therein avoids direct access of urine to the opening and the sealant (105) within the cartridge. The diverter is spaced by standoffs (182, 282) from the upper wall to provide a urine flow passage. A float (274) can be incorporated in the diverter to provide a visible signal of the presence of collected urine on the cartridge upper wall. A pre-treatment chemically-constituted tablet (210) held by a retainer (200) in the diverter provides sanitizing and/or deodorizing means. Post-treatment chemically-constituted tablets (224a) or pellets (224b) placeable at the outlet of the cartridge protect the drain pipe from corrosion and other harm.

  • Patent number: 6250331
    Abstract: The present invention is directed to a zero crack-pressure, high-flow valve assembly especially suited for use with blood salvage or recovery systems. The valve assembly cooperates with a valve seat defining an opening for selectively providing fluid communication between two adjacent chambers based on a pressure differential between the chambers. The valve assembly includes a disk coupled to a concentric ring support by a plurality of flexible or elastic arms, thereby permitting the disk to move relative to the ring support in a direction that is generally perpendicular to the plane of the ring support and the disk. The connecting arms also define fluid flow passages between the disk and ring support. The valve assembly is mounted so that the disk is normally spaced-apart from the valve seat, allowing fluid to flow between the two chambers. By increasing the relative pressure of the downstream chamber, the disk closes against the valve seat, blocking the opening.
