  • Patent number: 5082586
    Abstract: SO.sub.x /NO.sub.x pollution control reagent composition comprising from 0.1 to 25% urea in intimate admixture with dry, finely divided Nahcolite, a naturally occurring form of sodium bicarbonate. The composition is used in a process of removing SO.sub.x /NO.sub.x from the flue gases of utility and industrial plants, incinerators and the like by dry injection into a flue gas duct a sufficient distance upstream of a spent reagent collection device to provide above about 0.25 seconds of residence time of the reagent composition in the flue gas duct at temperatures in the range of above about F. followed by collection, preferably in an electrostatic precipitator. The Nahcolite reacts with the SO.sub.2 to form sodium sulfate and also removes NO.sub.x in the form of NO. The urea prevents the conversion of NO to NO.sub.2 by the Nahcolite, and maintains the concentration of the NO.sub.2 in the exit flu gases below the 50 parts per million visibility threshold (depending on ambient conditions).

  • Patent number: 5050924
    Abstract: The invention relates to an expandable tarpaulin comprising plastic or canvas materials, an X-pattern array of elasticized reinforcing and tie down straps or cords, and one or more elasticized perimeter cords. A problem with previous tarpaulins is that they are difficult to tie down over varying irregular sized loads. As a result, loose edges of tarp material flap in the wind causing distracting noise and damage to the vehicle, the load and the tarpaulin. Also the loose ends permit a wind tunnel effect which induces suction, loss of particulate loads causing road hazards. These problems are avoided by means of an expandable tarpaulin according to the invention which is characterized by a unitary expandable tarpaulin with elasticized reinforcing, tie downs, and perimeter hand holds, cord or straps. A safety reflective coating on selected portions of the tarp sheet may also be employed.

  • Patent number: 5013435
    Abstract: A system for removing impurities from liquids wherein the liquid is forced upward through several zones, the first zone being a bundle of tubes having a helical shape to present an inclined path where settling of particulates back down the tube occurs, then through a stack of filter modules which are over the bundle of tubes and contain treatment media, the arrangement of the filter modules being such that the passage of fluid in the upward direction removes particulates before flushing through the treatment media and agitates the treatment media so as to prevent packing. The helical form of the settling tubes and the modular arrangement provides a compact and inexpensive structure and great convenience for maintenance. The preferred cross sectional shape of each tube is oval to increase settling rate.

  • Patent number: 5002741
    Abstract: SO.sub.x /NO.sub.x pollution control process comprising injecting into flue gas from 1 to 50% carbon (preferably 5-15%) along with a dry, finely divided sodium sorbent, preferably sodium bicarbonate or Nahcolite, a naturally occurring form of sodium bicarbonate. The process removes both SO.sub.x and NO.sub.x from the flue gases of utility and industrial plants, incinerators and the like by dry injection into a flue gas duct a sufficient distance upstream of a particulate collection device, such as an ESP or baghouse, to collect spent reagent and additive. The sodium reagent reacts with the SO.sub.2 to form sodium sulfate and also removes NO.sub.x in the form to NO. The carbon additive reacts with NO.sub.2 to reduce the concentration of the NO.sub.2 in the exit flue gases to below the NO.sub.2 brown plume visibility threshold (about 30 ppm NO.sub.2, not corrected to 0% O.sub.2, depending on stack diameter and ambient conditions).

  • Patent number: 4999209
    Abstract: Simultaneous double reverse osmosis process for production of low and non-alcoholic beverages, particularly wines, from any traditionally fermented table wine feedstock. A portion of the feed wine is subjected to remove alcohol and water as a permeate, with recycle of the concentrated retentate, while simultaneously a volume-balanced amount of reverse osmosis water is input back into the feed tank to maintain the in process wine at the initial level of the feedstock wine. The process may be run batch-wise, alternately, or in a modified semi-continuous operation to produce non-alcoholic wines (wines having residual alcohol content of less than 0.01% by volume) low alcohol wires (less than 0.5 volume percent alcohol), or wines having reduced alcohol content (less than 11-13 volume percent). The process also overcomes the 5% alcohol barrier problem of conventional reverse osmosis. The resulting finished wine has flavor, aroma and color solids concentrations of a level acceptable in good commercial practice.

  • Patent number: 4981124
    Abstract: Method for improving the operation of a knock-controlled internal combustion engine of the type having a fault recognition system for detecting failed knock sensors comprising the steps of incrementally shifting ignition timing in response to an appropriate output signal from the fault recognizer (assuming a failed knock sensor). The preferred method provides for monitoring engine RPM exceeding a threshold value, whereby the fault recognizer is activated thereby causing the ignition timing to be incrementally shifted (retarded) with an added safety margin to a preset anti-block value. Upon sudden reactivation of a failed knock sensor, the fault recognizer is deactivated and the ignition timing is incrementally shifting to the optimum knock-control value as controlled by the knock sensor. That is, the active knock sensor overrides the preset value, but the ignition timing override occurs incrementally. For RPM below the threshold value the ignition timing is incrementally set back to knock-free settings.
