An anti-pressure system for a vessel which is subject to internal pressure created by heating or boiling of its contents, the system including first and second spaced-apart outlets for vapor to exit the vessel, each outlet having a first side communicating with the vessel interior and a second side

An anti-pressure system for a vessel which is subject to internal pressure created by heating or boiling of its contents, the system including first and second spaced-apart outlets for vapor to exit the vessel, each outlet having a first side communicating with the vessel interior and a second side communicating with the vessel exterior. The invention provides a reliable method of protecting a normally un-pressurized vessel, such as an autoclave, distillation vessel, boiler or the like, from dangerous pressure build-up, resulting from its vapor outlet being blocked, regardless of what other pressure release devices, if any, may be present on the vessel.

The invention claimed is: 1. An apparatus used in the distillation of materials, said apparatus comprising a vessel, a bag within the interior of said vessel for containing said materials, said vessel having an internal wall surface and an outlet for vapor to exit said vessel from the distillation

The invention claimed is: 1. An apparatus used in the distillation of materials, said apparatus comprising a vessel, a bag within the interior of said vessel for containing said materials, said vessel having an internal wall surface and an outlet for vapor to exit said vessel from the distillation of said materials, an anti-pressure system for said vessel, said anti-pressure system wherein said outlet has a first side communicating with said vessel interior and a second side communicating with the exterior of said vessel, a conduit extending downwardly into said vessel adjacent said internal wall surface of said vessel and between said bag and said internal wall surface, said conduit communicating with said second side of said outlet, said conduit having at least one opening in communication with said vessel interior to allow vapor from said vessel to enter said conduit through said opening and to exit said vessel through said second side of said outlet, said conduit being formed by an elongated shroud secured to an internal wall surface of said vessel, said second side of said outlet formed by an elbow communicating with said vessel exterior and said conduit communicating with and extending downwardly from said elbow. 2. The combination of claim 1 wherein said conduit opening is located along said internal wall surface of said vessel. 3. The combination of claim 2 wherein said conduit includes a plurality of openings located along said internal wall surface.
