  • Patent number: 9522346
    Abstract: Embodiments of the invention are directed to a sulfur trap comprising an inlet, a first chamber, a divider, a second chamber, an outlet, and a float assembly. The float assembly may have many different configurations, but generally comprises a float and plug, is configured to float within liquid sulfur, and is operatively coupled to a seal seat in the divider for sealing and unsealing the first chamber from the second chamber. Generally, only liquid sulfur is allowed to pass from the first chamber into the second chamber. However, the sulfur trap may be configured to allow for pressure relief, such that during an overpressure event the plug and seal seat disengage and allow the liquid-gas mixture to flow into the second chamber to prevent damage within the system. In some embodiments a filter and/or the flow of liquid sulfur is directed to collect debris from the liquid sulfur.

  • Patent number: 4708157
    Abstract: An air eliminator for liquid handling systems comprises a cylindrical container having a liquid inlet and a liquid outlet which are separated from one another by a cylindrical porous barrier positioned to subdivide the interior of the container into first and second chambers. The cylindrical barrier comprises a porous membrane which permits liquid to flow from the first chamber to the second chamber while preventing the passage therethrough of any gases which are entrained in incoming liquid supplied to the first chamber. Any such entrained gases accumulate in an air space located in the first chamber and are vented from the first chamber at atmospheric pressure. Liquid passing through the membrane, free of entrained gases, accumulates in the second chamber within the cylindrical barrier, and then passes to the liquid outlet via a modulating valve in the second chamber.

  • Patent number: 4173222
    Abstract: An apparatus for administering parenteral liquids from a parenteral fluid container which provides a sufficient quantity of parenteral liquid to be administered at a slower than normal rate so as to afford a keep-vein-open (KVO) means. The apparatus utilizes a first orifice to afford a faster flow rate than a second orifice spaced away from the first orifice. The preferred means for regulating different flow rates of fluid through the two orifices are the dimensions of the orifices and filters having different mesh sizes. When the parenteral liquid is maintained in the reservoir in contact with the first orifice with the faster flow rate, liquid will pass through both orifices at a predetermined regular rate. When liquid no longer contacts the first orifice, as when the fluid container is depleted of liquid, the second orifice then comes into effect to afford a slower rate of liquid until a new container can be supplied.
