  • Patent number: 8443739
    Abstract: Through the addition of tertiary air and a reduction of secondary air, NOx emissions from a waste-to-energy (WTE) boiler may be reduced. The tertiary air is added to the WTE at a distance from the secondary air, in a boiler region of relatively lower temperatures. A secondary NOx reduction system, such as a selective non-catalytic reduction (SNCR) system using ammonia or urea, may also be added to the boiler with tertiary air to achieve desirable high levels of NOx reductions. The SNCR additives are introduced to the WTE boiler proximate to the tertiary air.

  • Publication number: 20080163803
    Abstract: Having an indication of changes to the heating value of municipal solid waste (MSW) and having a means to control it before the MSW is fed to the boiler enables improved combustion control and increased capacity of waste-to-energy boilers. The moisture content of MSW has a significant impact on its heating value and on boiler efficiency when combusted. Changes in moisture content also change the density of the MSW. Directly measuring the density of the MSW prior to feeding it to the boiler permits controlled addition of additional water or liquid waste to reduce the variance of the MSW heating value.

  • Patent number: 6314422
    Abstract: A method is provided for accessing files on a client node which is connected to a server node across a network channel. A first file is displayed on the client node, and context information indicative of this first document is stored. Rather than using a “hard” link which specifies a specific path/filename, a dynamic softlinking process is used to access a second file. A link, similar to a hyperlink, can be selected on the first displayed file to access a second file, where the link includes information indicative of the second file. To determine a file identifier for the second document, a data structure, having a plurality of file identifiers, is accessed using the context information and link information. The second file can then be retrieved from the server node via the network channel using the file identifer and displayed on the client node.

  • Patent number: 6207208
    Abstract: A process for reducing the propensity of riboflavin-containing malt beverages employs the treatment of beer or its intermediates with Fuller's earth absorbents and, in particular, colloidal magnesium aluminum silicates, especially attapulgite and montmorillonite clays. This process effects absorbance of riboflavin contained in such beer or its intermediates and can be shown to improve the stability of a treated beer against the formation of skunky off-flavors following exposure to visible wavelengths of light.

  • Patent number: 6181992
    Abstract: The present invention relates to a system and method for diagnosing and isolating problems and for monitoring operting conditions on an automobile. The system includes a hand held unit and a master station which can operate alone or in unison to accomplish functions such as logging and displaying data on a real-time basis, logging data remotely and displaying the data at a later time, diagnosing fault conditions, monitoring operating parameters, reprogramming on-board vehicle controllers, displaying service manual and service bulletin pages and ordering parts on-line.

  • Patent number: 4654832
    Abstract: Sonobuoy parachute shroud line ends are retained by a cup mounted in and adjacent one end of the sonobuoy outer casing. A heavy ejection spring is beneath the cup for forcibly ejecting the cup outwardly from the one end of the casing. The cup is retained in the casing against the spring force by a pair of partially overlapping elongated plates each having one end releasably inserted in a circumferential slot in the outer casing, the slots being adjacent the casing one end and diametrically opposed. The upper plate is in retentive contact near the other of its ends by a first retainer rod pivoted at one of its ends to the cup bottom surface. The first rod contacts the upper plate near the pivoted rod end and is in retentive contact near its other end with a second retainer rod pivoted at one of its ends to the cup bottom surface. The second rod contacts near its pivoted end the first rod and is in retentive contact at its other end with a one shot spring motor driven pin.

  • Patent number: 4590590
    Abstract: A sonobuoy float canister is releasably latched to a wound cable pack container. The cable is attached at its upper end to the canister and at its lower end to a lower sonobuoy component. A rotor latches the canister and container together in one rotative position so that the cable is not unwound or payed out to provide a first or shallow depth deployment of the lower component. In a second rotative position of the rotor the canister and container are unlatched from one another and the cable is positively restrained after a predetermined partial payout to provide a medium depth deployment of the lower component. In a third rotative position of the rotor the positive restraint of cable payout is removed and the canister and container are unlatched so that the cable is fully payed out to provide for full depth deployment of the underwater component.
