Abstract: A method for cleaning and reclassifying electrical apparatus designed for use with PCB fluid electrolytes is described which is capable of operation on the site of the equipment being cleaned and while said equipment is energized.
Abstract: The present invention is directed to a solid waste conversion plan for the conversion of such solid waste as old tires to a gas or liquid hydrocarbon product, wherein the partial pyrolysis of the solid waste is carried out in a reactor having a grate in the lower section and a plurality of rotating fingers extending through the grate for preventing compaction of the solid waste in the reactor. The reactor, a heat exchange means and a stripper are connected in series. A blower is positioned between the heat exchange means and stripper for drawing oxygen-containing gas into the reactor and removing the gases formed therein and passing those gases through the heat exchange means and into the stripper.
Abstract: A fish landing net having a handle with two openings for receiving two flexible members which form a frame for supporting a net. The flexible members are made to telescope within the handle to reduce length. The flexible members are made for connecting and disconnecting the extended end of the flexible members.
Abstract: A burner assembly of the forced draft type includes a set of waste and oxidizer conduits which exit into the combustion zone of a combustion chamber. The combustion chamber includes a primary chamber and a secondary chamber formed by a lining of refractory within a metal housing. A nozzle is disposed at the outlet of the waste conduit to flare the spray of the fluid waste into the primary combustion chamber. The air conduits communicate with the primary combustion chamber about the periphery thereof. The nozzle end of the waste conduit causes the waste to become entrained with the combustion air moving adjacent the inner lateral walls of the primary combustion chamber. The air exiting from the plurality of air conduits is intercepted by the waste exiting from the waste conduit. The waste mixes with the air by turbulent flow, and the pressure of the air and waste creates a velocity sufficient to cause a back pressure within the primary combustion chamber.
Abstract: A system for removal of oxides of nitrogen from the waste gas produced by various combustion processes discloses thoroughly mixing the waste gas with ammonia by means of a static mixing element and then passing the resultant mixture through a catalytic reactor. The ammonia may be supplied by reacting a portion of the waste gas with natural gas in the presence of a catalyst.
Abstract: The present mounting chock is a system of elements designed to allow the chock to conform to non-rectilinear objects and to therefore allow greater flexibility in mounting objects to floors or decks. The invention includes right and left mounting elements, the right and left elements being mirror images in the vertical plane, and a spacing attachment means which is used to locate the right and left mounting elements relative to the mounted object and to each other which together comprise a mounting chock.
Abstract: The invention relates to a sealed housing for a bolt, including a nut body in threaded engagement with the bolt, and a housing which encloses the nut body. A lock cylinder locks the housing to an anchoring shoulder in the nut body. An elastomeric O-ring is disposed between a circumferential groove in the nut body and a gland bore in the housing.
Abstract: A radial ammonia converter system including first and second heat interchangers and first, second and third catalyst beds. The synthesis gas is heated in said first and second interchangers by catalyst bed effluent prior to full flow through each of the catalyst beds. In one embodiment, two of the catalyst beds are mounted with the first and second interchangers in one vessel; and in another embodiment, the first interchanger and second catalyst bed are mounted in one vessel and the second interchanger and first catalyst bed are mounted in a separate vessel. In both embodiments, the radial ammonia converter system is completed by a third catalyst bed in a separate vessel.
Abstract: The present invention is directed to an improved synthesis process and system for the production of ammonia. More specifically, the present invention involves the use of a split axial flow converter in the low pressure synthesis of ammonia.
Abstract: An improved process for the synthesis of ammonia utilizing three catalyst beds wherein the temperature of the synthesis feed gas and the effluent of at least one of the catalyst beds is controlled without the addition of quench gas.

Abstract: A pallet having a precast, prestressed concrete grillage superstructure including layers of elongate elements, each successively higher layer being transverse to the layer below it for heavy load bearing objects such as an industrial processing plant. The long elements are not only useful in providing the load-bearing points, but are useful in providing long channels between the elements which are useful as manways and for carrying pipe, conduits and the like that are associated with an industrial processing plant, the heavy load typically lifted and carried by such a pallet. The intersection points or junctions of the elements from layer to layer are load bearing points for distributing in radiating fashion the load placed on the top deck slab of the pallet. The pallet is suitable for transport by a submersible seaworthy vessel located beneath the pallet.
Abstract: A low energy process for the production of hydrogen-rich gas which involves the process sequence of primary reforming and secondary reforming includes parallel steam reformers for the primary reforming of the hydrocarbon feed, one portion of the hydrocarbon feed being heated using radiant heat, i.e., a steam reforming furnace, and another portion of the hydrocarbon feed being heated using indirect heat exchange with the effluent from the secondary reforming, i.e., an exchanger-reactor.

Abstract: A method of coloring a water-absorbable plastic partially or totally in a single color or multiple colors in such a manner that no migration or separation of the coloring agents used can take place. A copolymer of a coupler monomer and a water-absorbable plastic monomer, a polymer of a coupler polymer and a water-absorbable plastic monomer or a polymer of a coupler monomer and a water-absorbable plastic polymer is formed into an intermediate product shaped in the form of any desired final product. The intermediate product is immersed in an aqueous solution of a developer consisting of a diazonium double salt and allowed to swell, whereby the diazo-component of the developer penetrates into the plastic. The swollen product is then immersed in an aqueous acid or alkaline solution having an optimum pH value for coupling reaction to allow formation of an azoic dye on the plastic as a result of the coupling reaction.
Abstract: An improved synthesis loop for the production of ammonia has a low pressure, i.e. less than 100 atmospheres, a water absorption recovery system which utilizes low level heat recovered from the process for producing the synthesis gas to distill the ammonia-water mixture and an ammonia absorption refrigeration system which utilizes the same distillation column for both the water absorption system and the refrigeration system.
