Abstract: A full-flow filter is disclosed and which comprises a screen or element housed between two body halves. The construction of the filter is such that fluid to be filtered enters and exits the filter body from the same side thereof.

Abstract: An improved method of and apparatus for reconcentrating a liquid absorbent in an absorption system which method includes the steps of heating the rich liquid absorbent in a heating zone to vaporize a portion of the solute therefrom, flashing the partially reconcentrated absorbent into a flash separator and separating the lean liquid absorbent from the flashed vapors in the flash separator with the lean liquid absorbent being recycled to the absorption system and with the separated vapors being cooled to condense liquids and returning the stream of condensed liquids and vapors to the heating zone.

Abstract: A fuel reactor having an outer frusto-conical shell which is closed at one axial end and a fuel inlet at this axial end projects fuel axially into the outer shell and into an inner shell mounted coaxially therewith, the inner and outer shells being connected together at the discharge end of the inner shell, with the inner shell being open at its other end and axially spaced from the closed end of the outer shell. A tangential combustion air inlet is connected to the annular space between the two shells while a discharge nozzle is mounted on the discharge end of the inner shell. A number of circumferentially spaced tangential slots in the inner shell adjacent the nozzle scoop up some of the swirling air projected in through the tangential air inlet and direct some of the air onto the outer surface of the discharge nozzle so that it is cooled.

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 partially circular cutting edge positioned interiorly of the transition connection and forming, in conjunction with a non-cutting interior edge, an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge partially severs the disk whereby a portion thereof bends about an unsevered hinge portion and passes through the opening in the support member. The hinge portion of the rupture disk is supported by the non-cutting interior edge of 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.
