Abstract: The present invention relates to a safety pressure relief apparatus comprised of a reverse buckling rupture disk having a concave-convex portion connected to an annular flat flange portion by a curved transition connection and a support member having an annular flat flange portion for engaging the annular flat flange portion of the rupture disk and for supporting the transition connection thereof. The support member includes a cutting edge positioned interiorly of the transition connection and forming an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge severs the disk whereby a portion thereof passes through the opening in the support member. A bar for catching the severed portion of the disk after it passes through the opening in the support member is attached to the support member.

Abstract: The present invention relates to improved methods of manufacturing scored rupture disks whereby a coating of corrosion-resistant material is applied to the disks so that a score pattern is left unprotected thereon and the disks are contacted with a corrosive fluid for a period of time sufficient to corrode scores corresponding with the score pattern into the disks.

Abstract: A method of manufacturing an integral reverse buckling fluid pressure rupturable apparatus comprised of a support body formed of a ductile material having opposite ends and having a recess extending inwardly from one of the opposite ends, the internal terminus of the recess being positioned in close proximity to the other of the opposite ends of the body or to the terminus of another recess extending inwardly from the other of the opposite ends, whereby a relatively thin integral concave-convex rupturable portion is formed in the body having a known reverse buckling rupture pressure.

Abstract: A preassembled pressure relief apparatus adapted to be clamped between a pair of conventional pipe flanges. The apparatus is comprised of a pressure rupturable member supported between a pair of complementary supporting members which include seating surfaces to coact with the annular seating surfaces of the pipe flanges. The supporting members are of a size and shape such that portions thereof extend radially outwardly beyond the boundaries of the annular seating surfaces, of the pipe flanges and means for clamping the supporting members and the pressure rupturable member together in preassembly are attached to such portions of the supporting members.

Abstract: The present invention relates to packaged apparatus for controlling the hydrocarbon dewpoint of a gas stream particularly adapted for use in a cold environment. A weather-tight enclosure is provided which includes a liquid desiccant dehydration unit for dehydrating the gas stream and means for cooling the dehydrated gas stream whereby a residue gas stream having a desired hydrocarbon dewpoint is produced. Portions of the dehydration unit and means for cooling the gas stream extend outside the enclosure so that they are subjected to the cold environment and are cooled thereby and heat generated by the dehydration unit and means for cooling the gas stream is utilized to heat the interior of the enclosure.

Abstract: The present invention relates to methods and systems for generating a dehydrated inert gas stream. By the methods of the invention a mixture of fuel and air is combusted to generate a stream of hot inert gases containing water vapor. Heat is removed from the stream of hot inert gases so that the gases are cooled and the cooled inert gases are contacted with a stream of liquid absorbent having an affinity for water vapor thereby dehydrating the stream of inert gases. The heat removed from the stream of hot inert gases is utilized to reconcentrate the stream of liquid absorbent.

Abstract: The present invention relates to apparatus for incinerating combustible wastes wherein a pilot light for igniting the wastes is provided at a location remote from a source of fuel for said pilot light. By the present invention, a pilot light burner is provided at the remote location and a fuel jet-ejector for producing a combustible mixture of fuel and air is provided at the location of the source of fuel. A first conduit connects the fuel-air mixture discharge connection of the jet-ejector to the pilot light burner and a second conduit connects the source of fuel to the fuel inlet connection of the jet-ejector. A third conduit is provided connected to the second conduit and to the pilot light burner for conducting fuel directly to the burner separately from the fuel-air mixture conducted thereto by way of the first conduit.
