  • Patent number: 10675561
    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: 10675454
    Abstract: Fluid transfer device and method that allows for sterile wet connections, allows the connection to be reversed, and allows the connection to be reconnected, while leaving the connectors sterile and reusable under pressure. In certain embodiments, the device includes a first member and a second member, the latter adapted to receive the former in locking engagement upon actuation of the device to create fluid communication between the two in a sterile manner. Each of the members include a door that when opened, allows the first member to be linearly displaced into the second member to allow fluid to be transferred. When fluid transfer is complete, the first member can be retracted from the second member, and the doors closed.
