Title: Liquid atomization methods and devices
Inventor: REESE BRIAN T
IPC: B05D1/02
Filed: 2000-09-21
Granted: 2008-03-25
Abstract: The present invention involves controlled atomization of liquids for various applications such as particle/droplet seeding for laser-based measurements of flow velocity, temperature, and concentration; flame and plasma based elemental analysis; nano-powder production; spray drying for generation of small-sized particles; nebulizers in the production of sub-micron size droplets and for atomizing fuel for use in combustion chambers. In these and other atomizer applications the control of droplet and/or particle size is very critical. In some applications extremely small droplets are preferred (less than a micron), while in others, droplet diameters on the scale of several microns are required. The present invention has the flexibility of forming droplets within a particular range of diameters, wherein not only the size of the average droplet can be adjusted, but the range of sizes may be adjusted as well. The atomizer (4) itself is in the form of a heated tube (44) having an inlet end (48) and an outlet end (50). As liquid travels through the tube it is heated and upon exiting the tube and entering a reduced pressure area the liquid atomizes to form very fine droplets. By electrically heating the tube by passing a current therethrough, the heating adjustment can be performed on-the-fly, allowing droplet size adjustment during operation of the atomizer. Several different embodiments of the atomization device are disclosed.

Abstract: The retrofitting of an existing methanol or methanol/ammonia plant to make acetic acid is disclosed. The existing plant has a reformer (10) to which natural gas or another hydrocarbon and steam (water) are fed. Syngas is formed in the reformer (10). All or part of the syngas is processed to separate out carbon dioxide (24), carbon monoxide (30) and hydrogen (32), and the separated carbon dioxide (24) is fed either to the existing methanol synthesis loop (12) for methanol synthesis, or back into the feed to the reformer (10) to enhance carbon monoxide formation in the syngas (18). Any remaining syngas (38) not fed to the carbon dioxide separator (22) can be converted to methanol in the existing methanol synthesis loop (12) along with carbon dioxide (24) from the separator (22) and/or imported carbon dioxide (25), and hydrogen (35) from the separator (28). The separated carbon monoxide (30) is then reacted with the methanol (36) to produce acetic acid (40) or an acetic acid precursor by a conventional process.  Also disclosed is the reaction of separated hydrogen (32) with nitrogen (52), in a conventional manner, to produce ammonia. Also disclosed is the reaction of a portion of the acetic acid (40) in a conventional manner with oxygen (46) and ethylene (44) to form vinyl acetate monomer (48). The nitrogen for the added ammonia capacity in a retrofit of an original methanol plant comprising an ammonia synthesis loop (33), and the oxygen (46) for the vinyl acetate monomer process (42), are obtained from a new air separation unit (50).

Granted: 2010-12-21
Abstract: The present invention provides an earplug having a plurality of visual zones. In one embodiment, the earplug includes a first visual zone, a second visual zone, and a third visual zone. The first, second, and third visual zones each comprise continuous longitudinal color bands each of which extends completely around the circumference of the earplug. In one embodiment, at least the second visual zone intermediate the first and third visual zones is formed of a color which is distinctly different from the colors of the other visual zones. In another embodiment, the first, second, and third visual zones each have one color which is distinctly different than the other colors. Accordingly, the first, second, and third visual zones comprise visual zones which permit an observer or the wearer to immediately ascertain the depth of insertion of the earplug by simply viewing the earplug. In one aspect, this permits a safety officer or other individual, including the wearer, to easily determine whether the wearer is complying with existing safety rules and regulations. In another aspect, this permits the wearer to determine whether a proper fit exists between the earplug and the ear canal because each of the visual zones indicates the degree of insertion into the ear canal.

Granted: 2006-06-06
Abstract: A method is disclosed for manufacturing a pharmaceutical tablet for oral administration, the tablet combining both immediate-release and prolonged-release modes of drug delivery and using an immediate-release drug that is either insoluble in water or only sparingly soluble and is present in a very small amount compared to the prolonged-release drug. The method involves the use of particles of the immediate-release drug that are equal to or less than 10 microns in diameter, applied as a layer or coating over a core of the prolonged-release drug, the layer or coating being either the drug particles themselves, applied as an aqueous suspension, or a solid mixture containing the drug in admixture with a material that disintegrates rapidly in gastric fluid. The result in both cases is a high degree of uniformity in the proportions of the immediate-release and prolonged-release drugs, uniformity that is otherwise difficult to achieve in view of the insolubility of the immediate-release drug and its relatively small amount compared to the prolonged-released drug.

Abstract: A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) (610) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network (380) to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interfere directly with the optical communication network.
