Abstract: The purpose of this device is to give assistance to a person that is standing in a particular area for an extended amount of time. This is achieved for people of different heights by having a rotating joint at the base. A saddle joint at the base of the housing enables this device to be adjustable. The seat portion can rotate to adjust to different people. This supporting system is designed to bear some of the load while standing, to accommodate a more ergonomic environment for the person standing.

Abstract: A method of facilitating movement of a vessel in a specific navigation environment. Characteristics of the vessel are evaluated relative to conditions in the environment to define a navigation procedure. The procedure is described on a navigational chart that includes information from sources of navigation-related experience, e.g., sovereign governmental authorities, hydrographic offices, port authorities, communication authorities, vessel masters, operators and port pilots. The vessel is indicated as geographically referenced to points in the environment indicative of successive positioning of the vessel in accordance with the procedure. Using such procedures can streamline coordination among masters, operators and ports and can shorten time needed to plan and perform navigation in complex environments.

Abstract: A system for simulating conditions along a route traveled by a mobile platform (such as a train, marine vessel, aircraft or automobile) is provided. The system includes a source of user input. The system also includes a navigation control module that generates navigation data. The navigation data includes a route for the mobile platform based upon at least the user input. The system further includes a conditions control module that determines at least one condition associated with the route. The at least one condition includes at least a lighting condition associated with the travel of the mobile platform along the route.

Abstract: A computer anti-virus system is disclosed. The computer anti-virus system can have multiple detection layers and can include a first memory and a second memory. The computer anti-virus system can have a reduced first memory size requirement for a fingerprint signature based anti-virus application program by putting off to the second memory those signatures that are redundantly detected on other layers. Thus, performance can be enhanced and/or costs can be reduced.

Abstract: Apparatus to convert LNG to gas, comprising a vaporizer having passages to pass the cool or cold LNG in heat transfer relation with warming gas flowing downwardly to discharge in multiple directions, and flow control means to control discharge of the gas flow in selected direction or directions, as a function of wind direction.

Abstract: In apparatus to convert cryogenic fluid to gas, a vaporizer having passages to pass the cool or cold cryogenic fluid in heat transfer relation with warming gas flowing downwardly through the vaporizer, the vaporizer having surfaces on which ice collects and from which ice falls to the base of the vaporizer and collects in a pile, and removing fluid flow control means operating to direct flow of removing fluid at the ice pile with sufficient force to cause removal of such ice in the pile relative to the vaporizer base.

Abstract: This invention relates prolonging operation duration of ambient air heated vaporizers of cryogenic fluids; and more particularly concerns a method for enhancing ice removal under such vaporizers. Ambient air vaporizers have been used in the past to convert cryogenic fluids into warm gas. Because of the very cold surfaces inherent in the construction of these vaporizers, they collect frost or ice, and are generally limited in the time they can be effective due to the reduction in heat transfer caused by the frozen atmospheric water collecting on vaporizer surfaces. Operators frequently seek to mitigate this effect by having multiple vaporizers, alternately switching units on and off, allowing them to defrost. A characteristic of these defrosting vaporizers, is the falling of the frost and ice off the heat transfer surfaces, collect at the base of the unit (the “Pile). This Pile of frozen water or slush generally can be melted by exposure to warm ambient air during the defrost cycle.

Abstract: The method of processing air prior to separation of such air into gaseous components, the steps that include: first compressing a stream of air and cooling the compressed air, to enable water separation and removal from the stream, to provide a dry stream of air; then further compressing the dry air stream and cooling the compressed dry air stream to enable removal of contained remanent water; then expanding the cooled air stream in an expansion stage which extracts work from the expanding stream; then passing the expanded air stream to a separator operating to remove water from the stream, thereby producing dry air passed to a component gas separation stage or stages.

Abstract: A separation process, the steps that include: providing an expansion zone, flowing a gaseous fluid into and through the expansion zone, flowing a spray of liquid droplets into the expansion zone to mix with the gaseous fluid and produce nucleation sites, then expanding the flow of mixed gaseous fluid and liquid droplets to cause condensation of gas onto the liquid droplets, and then centrifuging liquid droplets into a separation layer.

Abstract: The method of separating liquid from gas in a flow stream, that includes expanding the flow stream at a first zone to reduce flow stream pressure and increase flow stream velocity; centrifugally separating liquid from gas in the expanded flow stream, in a second zone; and increasing the pressure of the gas, from which liquid has been separated, by converting kinetic energy of the gas into pressure, at a third zone.
