  • Patent number: 6289266
    Abstract: A method of controlling operation of a particulate fuel burning boiler, such as a coal fired boiler, having a plurality of burners each receiving pulverized coal, primary air and secondary air. The flow rate of the pulverized coal, primary air and secondary air is determined independently for each burner and is compared with a model. In the event that the comparison results in a determination that one or more of the flow rates depart from the desired rate by a predetermined amount, a control signal is emitted to adjust the air to flow ratio entering the specific burner. The control signal which alters the air to fuel ratio may result in alteration of the air or fuel flow rates. The method may be employed to reduce NOx emissions, loss on ignition and to optimize heat rate.

  • Patent number: 6256522
    Abstract: Apparatus and method for measuring properties of certain analytes are provided. The apparatus includes a sensor capsule having a processing chamber defined by a wall which in one embodiment has a semi-permeable membrane permeable to the analyte as at least a portion thereof. Receptor material is disposed within the chamber and is capable of chemically interacting with the analyte. In one embodiment, at least a portion of the sensor is translucent. A light source, which may be an optical fiber, causes light to impinge on a translucent portion of the capsule and pass therethrough. Responsive fluorescent light is generated and emitted. This light may be received by detector means and processed in a conventional manner to determine concentration of the analyte. A dye-labelled analog-analyte may be provided within the chamber. Both the receptor material and analog-analyte are of such size that they will not pass through the semi-permeable membrane although the analyte can.

  • Patent number: 6251611
    Abstract: A method of determining the presence of chronic volume dependent hypertension is provided wherein a determination is made as to whether there has been a substantial reduction in phosphorylation of the blood-derived protein or renal proximal brush border membrane protein and if such reduction exists concluding that chronic volume dependent hypertension exists in a patient. The method may advantageously be practiced by employing blood serum or blood plasma as the body specimen containing the protein in determining whether a patient has chronic volume dependent hypertension, a cellular component of the blood, such as a blood-derived protein coming from the plasma membrane of lymphocytes. The method may include subsequent therapeutic patient treatment. Related diagnostic apparatus is also provided.

  • Patent number: 6241957
    Abstract: A method of making anisotropic carbon foam material includes de-ashing and hydrogenating bituminous coal, separating asphaltenes from oils contained in the coke precursor, coking the material to create a carbon foam. In one embodiment of the invention, the carbon foam is subsequently graphitized. The pores within the foam material are preferably generally of equal size. The pore size and carbon foam material density may be controlled by (a) altering the percentage volatiles contained within the asphaltenes to be coked, (b) mixing the asphaltenes with different coking precursors which are isotropic in nature, or (c) modifying the pressure under which coking is effected. In another embodiment of the invention, solvent separation is employed on raw bituminous coal and an isotropic carbon foam is provided. A related carbon foam product is disclosed. The carbon foam materials of the present invention are characterized by having high compressive strength as compared with prior known carbon foam materials.

  • Patent number: 6219990
    Abstract: A method of forming and using a metal I-beam includes hot rolling an elongated metal workpiece to establish a web and a pair of flanges on the edges thereof. The web is formed with elongated reinforcement of solid cross-section having a generally straight longitudinal axis oriented generally parallel to the flanges. The hot rolled I-beam is cooled without forming substantial waves in the web and the I-beam is subsequently secured in a building construction or other structural product. The method involves the longitudinally oriented reinforcing means which preferably are one or more elongated laterally projecting ribs having such mass that the average temperature of the web prior to cooling will be sufficiently close to the average temperature of the flanges prior to cooling that the formation of waves within the web during cooling will be resisted. The reinforcement is preferably coextensive with the I-beam. The web is preferably substantially continuous.

  • Patent number: 6214237
    Abstract: A process for the treatment of a solid waste slurry formed from solid waste particles mixed with a liquid includes delivering a solid waste slurry to a first solid-liquid separation means for separating a first amount of the solid waste particles from the slurry, followed by delivering the solid waste slurry from the first solid-liquid separation means to a tank where the solid waste slurry is stirred to maintain the solid waste particles in suspension. The solid waste slurry is then discharged from the tank with a portion of the solid waste slurry being recirculated back to the tank while a second portion of the solid waste slurry is delivered to a second solid-liquid separation means for separating a second amount of the particles from the slurry.

  • Patent number: 6211952
    Abstract: A method and apparatus are provided for inspecting glass containers for checks. The container finish is illuminated from the exterior and light reflected from a check is detected by the apparatus. In one embodiment, the glass container finish is inspected for horizontal and related diagonal checks and, in another, the glass container finish is inspected for vertical and related diagonal checks. The checks redirect the normal beam of light and thereby permit the reflected light to be delivered to a detector which converts the received light into a corresponding electrical signal which is compared to a standard in order to determine whether the container should be rejected. The method eliminates incorrect inspection results due to reflection of light caused by threads, lugs, mold seams, takeout beads and the sealing surface of the container mouth. The vertical and horizontal embodiments may be combined into a single system which inspects for vertical, horizontal and diagonal checks.
