Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: The Collapsible Support Frame for Kinetic Energy Penetrator supports a long-rod kinetic energy penetrator inside a kinetic energy missile air frame in handling and flight environments but, upon impact of the missile on the selected high-obliquity target, gives way. This greatly reduces the lateral loading inflicted on the penetrator by the interaction of the missile body and the target and consequently maximizes the effectiveness of the penetrator against the target. The Collapsible Support Frame comprises concentric outer and inner rings that are mounted inside the missile and designed to hold and support the penetrator. When the missile strikes the target and the extremely high impact shock loading conditions of the penetrator process occurs, the outer ring captures a high impact shock loading pulse and transmits it to the inner ring, whereupon the inner ring fails in its supportive function, thus freeing the penetrator.

Abstract: A method is disclosed for the addition of an oxygen-containing gas under certain defined process conditions, to an off-gas stream derived from an FCC regenerator which is operated in a partial mode of combustion. The off-gas from the regenerator contains 1-6% CO by volume and at least 300 ppm nitrogen compounds comprising NH.sub.3 and HCN. Without the addition of an oxygen-containing gas, roughly 25 percent of the NH.sub.3 and HCN are converted to NO.sub.x in downstream CO boilers. A preferable method of this invention comprises the addition of heated air (20% O.sub.2) into the regenerator off gas to produce an off gas stream having a temperature of 1260.degree. F. to 1500.degree. F.

Abstract: A novel fuel burner is disclosed for the combustion of fuel in the presence of flue gas and water added to the nozzle tip in a liquid phase through a water outlet means at the nozzle. Steam is used as an indirect heat exchange fluid to cool the steam to water (used in the combustion) and to heat the flue gas passed to the burner. The orifices of the water outlet means are configured to insure a sufficient amount of water flow to reduce NO.sub.x (by increasing the amount of flue gas) and to insure that the flame of the burner is not extinguished.

Abstract: The invention is a process for combusting a gaseous fuel in a burner to result in low NO.sub.x emissions by first feeding a gaseous fuel stream and an air stream to a premixer where the fuel and air streams are mixed to form a fuel-air mixture. The fuel and air streams are fed to the premixer at a fuel to air equivalence ratio of less than 1 (i.e., fuel-lean). Second, the fuel-air mixture is passed to a combustion chamber where the fuel is substantially combusted to produce a combustion chamber jet and flue gases. The combustion chamber jet and flue gases pass into a heating zone which may include a furnace, heater, or boiler. Third, at least two high-velocity fuel streams, optionally diluted with a nonreactive thermal ballast, are passed to the heating zone contemporaneously with the second step. The high-velocity fuel streams entrain at least a portion of the flue gases. The fuel in the high-velocity fuel streams is partially combusted prior to coming into contact with the combustion chamber jet.

Abstract: A tandem warhead missile arrangement that has a composite material housing structure with a first warhead mounted at one end and a second warhead mounted near another end of the composite structure with a dome shaped composite material blast shield mounted between the warheads to protect the second warhead from the blast of the first warhead.

Abstract: An improved fluid dispensing system for use in dispensing beverages including unitary fluid filter cartridge adapted to be immersed in fluid to be dispensed, the fluid filter cartridge including a cannister having inlet and outlet openings in the lower end thereof, a filter septum in the filter cartridge connected to the outlet, adsorptive material disposed in the cartridge, a check valve controlled vent opening in the upper end of the cannister, and a riser stack connected to the check valve controlled vent opening.

Abstract: A regeneration zone for fluid catalytic cracking contains ammonia (NH.sub.3) when the regeneration zone is operated in a partial combustion mode as defined by a content of CO of between 1 and 6 percent by volume. If the ammonia is not removed from the regeneration zone off gass, the same will be passed to a CO combustion zone where, in the presence of oxygen, CO is oxidized to CO.sub.2 and some of the ammonia will undesirably be oxidized to NO.sub.x. This invention reduces the presence of ammonia in the feed gas to a CO combustion zone of an FCC process by the introduction of a NO.sub.x -containing gas to dilute phase of a regeneration zone or to a regeneration zone off gas. Ammonia, NO.sub.x and oxygen present in the regeneration zone off gas of the regeneration zone, will tend to react to produce nitrogen and water vapor, which then is passed to the CO combustion zone for CO oxidation to CO.sub.2. Where the addition of NO.sub.x is made at temperatures greater than 1700.degree. F.

Abstract: The present invention pertains to an oil atomizer suitable for use with a heavy liquid fuel which is constituted by a cylindrical body for delivery of the heavy liquid fuel to an atomization zone, spray tubes in the atomization zone arranged about the periphery of a conical cap terminating the cylindrical barrel and a shroud surrounding the cylindrical barrel and permitting passage therebetween and a shroud tip terminating the shroud and enclosing the cap, the spray tubes being inserted through openings in the shroud tip which permit passage of air or other fluid around the spray tubes.
