  • Publication number: 20040018132
    Abstract: An emission control system for reducing NOx in the exhaust of a diesel engine. A partial oxidation system receives diesel fuel from the engine's fuel tank and partially oxidizes the diesel fuel into hydrogen. The hydrogen is then introduced into the main exhaust line and the hydrogen-enhanced exhaust is delivered to a hydrogen selective catalytic reduction unit, which uses the hydrogen to convert the NOx to nitrogen.

  • Publication number: 20030122617
    Abstract: Various methods and apparatuses that multiply the effects of feedback current on an amplifier. In an embodiment, a buffer circuit controls the transition rate on an output pad of the buffer circuit. An amplifier has an input terminal and an output terminal. The output terminal couples to the output pad. A feedback component couples feedback current from the output pad to the input terminal. A current mirror multiplies the effects of the feedback current on the input terminal without increasing the feedback current through the feedback component.

  • Patent number: 6523635
    Abstract: A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms.

  • Publication number: 20020194028
    Abstract: A method, apparatus, and readable medium for presenting an Internet or Intranet accessible patient evaluation system. Medical evaluation forms are presented to users over a transmission channel such that a user at a browser may access previously prepared forms of patients, editing those forms, or enter evaluation data for a new patient. A generator uses form data stored in a configuration database to generate HTML/ASP page documents in which users can view previously entered data or add new data. The interaction between the generator and a configuration module containing the loaded configuration database is dynamic, as when the configuration database changes or is updated the generator is caused to generate new HTML/ASP page documents to correspond to the changed configuration database.

  • Publication number: 20020133509
    Abstract: A process of accessing data in a database, inputting the accessed data to a form, using the form with the accessed data by a first user, monitoring the database to detect changes to the accessed data by a second user while the form is being used by the first user, updating the accessed data in the form while being used by the first user in accordance with rules corresponding to the detected changes, and displaying update status of the accessed data in accordance with the updating. The update status can indicate if the accessed data has not been changed since the first user began using the accessed data; if the first user has changed the accessed data; and if the second user has changed the accessed data while the first user is using the accessed data. The process can be implemented in a standalone processing device or in a network.

  • Patent number: 6308580
    Abstract: A Coriolis flowmeter sensor having a reduced flag dimension. In order to have a reduced flag dimension, the entire length of the flow tubes must vibrate to make the flowmeter sensor more sensitive to Coriolis effects. When the entire length of the flow tubes vibrate, a first set of brace bars connected to the flow tube separates the frequencies of vibration in the flow tubes. A second set of brace bars connected to the flow tubes enhances the zero stability of the flowmeter.

  • Patent number: 6177599
    Abstract: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of oxychlorination which yields reduced levels of environmental toxins such as, chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans. The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms. The oxychlorination process consists of contacting the hydrocarbon reactant with oxygen or oxygenated gas and at least a portion of externally obtained hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150° C. to 600° C. and recovering chlorinated hydrocarbon from the effluents of the reaction zone.

  • Patent number: 6170692
    Abstract: The present invention discloses an animal waste bag dispenser and disposal unit comprising a mounting bracket, a container for holding bags, having a bucket and lid, and a receptacle. The container and receptacle are attached to the mounting bracket by nuts and bolts which extend through apertures positioned along the length of the mounting bracket. Bands wrapping around the mounting bracket through a plurality of notches enable the bracket to be attached to a pole or tree. These bands allow the height of the unit to be adjusted to a convenient level along the pole. The front side of the bucket has an opening through which bags contained inside can be retrieved. The bucket is covered by a lid having a lip which extends downward from the lid over the bucket. The lid prevents the natural elements, namely rain and snow, from seeping into the bucket; thus, the bags contained within the container remain dry and clean.

  • Patent number: 5892377
    Abstract: A method and apparatus for reducing leakage currents in a high voltage tolerant I/O buffer. An I/O buffer designed to tolerate high external voltages by blocking such voltages at a passgate in a p-output path that uses a device between a p-driver gate node and a p-gate node of the passgate to ensure that the p-transistor of the passgate is turned on when the p-driver is driving the pad high. A second device isolates the p-gate node of the passgate from the pad until a pad voltage reaches a predetermined level. Once the pad voltage reaches the predetermined level, the device drives the voltage at the p-gate node of the passgate to that of the pad. Maintaining the p-transistor of the passgate on while the p-driver is driving the pad high allows a rapid hard shut-off of the p-driver as the I/O buffer tri-states the pad.

  • Patent number: 5815013
    Abstract: The present invention provides an output buffer having a self back-bias compensating circuit that adapts the effective output transistor size to overcome current-reducing threshold voltage shifts caused by connection of the output n-wells to a high voltage. More particularly, this invention provides a circuit configuration in which bias level detection is used to switch in additional PFET legs under high back bias conditions. The extra driver legs are disabled under zero back bias. This compensates for the effect that different voltage switching environments have on PFET performance.

  • Patent number: 5750812
    Abstract: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of a once-through air-based oxychlorination process which yields reduced levels of environmental toxins such as chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans. The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms. The oxychlorination process consists of contacting the hydrocarbon reactant with air or oxygen enriched air and hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150.degree. C. to 600.degree. C. and recovering chlorinated hydrocarbon from the effluents of the reaction zone. The improvement consists of the use of air which is pretreated before use in the operated oxychlorination process by a means for removal of the aromatic hydrocarbons.
