  • Patent number: 6116021
    Abstract: A method for monitoring the performance of a catalytic converter (34) computes the oxygen storage capacity and desorption capacity of a catalyst within the catalytic converter (34). An engine control unit (10) receives mass flow rate information of air from a mass air flow rate sensor (12) and an injector driver (24), and receives electrical signals from an upstream exhaust gas sensor (28) and a downstream exhaust gas sensor (30). A rate modifier is determined from excess air ratios and an adaptation parameter. The engine control unit (10) calculates normalized air fuel ratios for the exhaust gas entering and leaving the catalytic converter (34) and performs numerical integration using the rate modifier to determine the oxygen storage capacity of the catalyst in the catalytic converter (34). The calculated oxygen storage capacity of the catalyst can be compared with threshold values to determine the performance of the catalytic converter (34).

  • Patent number: 6116023
    Abstract: For proper treatment of NOx released from NOx absorbent catalyst as well as HC and CO in exhaust gas, a measure of A/F of exhaust gas downstream of the NOx absorbent is used as the input to a feedback control loop. The feedback control loop alters a feedback correction factor (or coefficient) of a fuel control command applied to each fuel injector in such a direction to decrease a deviation of the actual A/F input from a target A/F (stoichiometry or rich) When the measure of A/F has switched the side to rich, a measure of A/F of exhaust gas upstream of the NOx absorbent catalyst is used as the input to perform usual feedback control loop to maintain lean combustion mode.

  • Patent number: 6116025
    Abstract: This pneumatic stroke reversal system for reciprocating, linearly driven pumping units is completely automatic in its cyclic operation, and greatly improves efficiency. A smaller drive motor is required because kinetic energy is stored at the end of each stroke, to be returned to the system to assist in beginning and accelerating the following stroke, and because the smooth and controlled reversals allow a substantially higher stroke velocity and production from a unit of a given size. The reversals are effective on both the upstroke and the downstroke, and their maximum net values are individually selectable over a wide range, and adjustable in the field. The exact points of direction change occur at the instant of maximum rod stretch and maximum rod contraction, respectively, thereby greatly reducing parasitic rod string oscillation, and reducing pressure peaks on, and problems with, the rod string.

  • Patent number: 6116032
    Abstract: A method for reducing particulate generation from regeneration of cryogenic vacuum pumps. The method comprises controlling a pressure ramp rate inside the cryopump during an initial introduction of a regeneration gas into the cryopump. Preferably, the pressure ramp rate is controlled by maintaining a first pressure ramp rate, preferably between about 0.03 T/s and 0.15 T/s, until a first pressure of about 0.3 T is reached inside the cryopump and maintaining a second pressure ramp rate between about 1 T/s and 5 T/s until the surface in the cryopump reaches an intermediate temperature between about 40 K and 100 K. Preferably, the temperature ramp rate is also controlled by heating the surface at a temperature ramp rate between about 0.1 K/s and about 0.5 K/s until the intermediate temperature has been reached. Preferably, the temperature ramp rate is controlled by regulating the flow of an inert gas into the cryopump using a flow restriction device.

  • Patent number: 6116033
    Abstract: While water sprayed from an air washer is consumed by humidification, excess water which is not consumed accumulates in a circulating water tank and is supplied to the air washer again through a heat exchanger by a circulating pump. Water is supplied to the heat exchanger through a piping to make up for a shortage of water, where the water is cooled and fed to the air washer. Accordingly, the water supplied to the air washer is composed of excess humidification water from the circulating water tank which is circulated by the circulating pump and water supplied through the piping, and the water from two sources is supplied to the air washer after being cooled by the heat exchanger. Thus the excess humidification water stored in the circulating water tank has a temperature lower than the room temperature and can prevent propagation of micro-organisms which can propagate at a room temperature.

  • Patent number: 6116049
    Abstract: A nozzle for producing a continuous gas/solid or gas/aerosol stream from a liquid having a high room temperature vapor pressure. The nozzle comprises a series of expansion stages, with the flow reversing direction after each expansion except the first and going over the conduit which comprised the previous expansion stage. In addition, the flow from the last expansion stage comes in contact with the inlet conduit, thereby exposing the inlet flow to the cold temperature produced in the nozzle. Since the flow in the nozzle is essentially adiabatic, the expansion in each stage takes heat from the flow in the previous stage, ultimately resulting in very low temperature flow. It is particularly useful as a fire extinguisher since it can produce solid CO.sub.2 snow and an aerosol of HFC-23 that are "thrown" by the remaining gaseous CO.sub.2 and HFC-23 at low exit velocities. This means that these agents can be used on Class A fires. A test nozzle using 1 liter (2.

  • Patent number: 6116051
    Abstract: A technique is set forth to reduce the heat requirement of conventional distillation processes which separate feed mixtures containing three or more components. The technique provides a great deal of flexibility in adjusting the temperatures of the required utilities including a scenario where the heat requirement is reduced without a need for additional higher temperature (and more costly) heat utility. In this technique, when a liquid bottoms stream (or gaseous overhead stream) containing two or more components is sent from an earlier column to a subsequent column, then a return vapor (or liquid) stream is implemented between the same locations in the two columns.

  • Patent number: 6116057
    Abstract: The present invention relates to a method of producing three-dimensional knits. In accordance with the invention narrowing the loops is done by loops covering a partial area of the needle bed being transferred to needles arranged nearer to the middle of the knit and subsequently knitting further continued, and widening the loops is done by loops covering a partial area of the needle bed being transferred to needles arranged remote from the middle of the knit and subsequently knitting further continued. As an alternative to this, needles may be rendered inactive in a partial area of the needle bed over at least one course and subsequently reactivated.

  • Patent number: 6116061
    Abstract: A washing machine includes an outer tub, an inner tub, fluid nozzle configured to spray fluid into the inner tub, a fluid pump, and a controller. The washing machine may also include a pulsator located in the inner tub for applying a force to clothing in inner tub. During a first washing cycle, the controller causes the inner tub to rotate, and the nozzle to spray fluid onto clothing in the inner tub. During the first washing cycle, a fluid level in the outer tub may be controlled so that it is lower than the inner tub. During a second washing cycle, the inner tub is held stationary, and the pulsator applies a force to clothing in the inner tub, as occurs in conventional washing machines. Because the fluid level in the washing machine can be kept quite low during the first washing cycle, less water and less detergent is required. Also, because the level of the water is kept below the rotating inner tub during the first washing cycle, less force and thus less energy are required to rotate the inner tub.

  • Patent number: 6116066
    Abstract: An electronic combination lock having a dial-shape handle with a keypad incorporated therein is disclosed. Rotation of the handle extends or retracts a bolt that closes or opens the lock. The keypad includes indicia that give the user visual cues as to the orientation of the handle, thereby informing the user of the extended or retracted condition of the bolt. A battery pack is used to energize circuitry that recognizes a code entered through the keypad. The circuitry provides a control signal that activates a solenoid to extend or retract a bolt blocking device, which in turn prevents or enables movement of the bolt. A visual indicator warns of a low voltage or power condition in the battery pack. Electrical contacts are provided in the face plate of the handle to connect the circuitry to an external power source in case the battery pack fails.
