  • Publication number: 20020168289
    Abstract: A sterilization system (14) includes a sensor (10) for detection of a component, such as hydrogen peroxide vapor, in a multi-component vapor, such as a mixture of vapor hydrogen peroxide and water supplied to a chamber (12) of the system. The sensor preferably uses a wavelength range in which hydrogen peroxide strongly absorbs but other components of the vapor, such as water, do not. A suitable wavelength for detection of hydrogen peroxide is from about 7500 to about 8400 nm, since there is little absorption by water in this range. This avoids the need to use complex subtraction procedures normally used to remove the contribution of water from detected absorbance measurements. A control system (16, 30) controls operating conditions of the sterilization system, such as a heater (82), pressure release valves (74), vaporization rate of hydrogen peroxide by a vaporizer (22), and the like to maintain optimum sterilization conditions within the chamber.

  • Patent number: 6337054
    Abstract: The invention relates to a method in autoclaves, the autoclave being divided into imaginary areas, the areas being heated by the feeding of steam into the areas in order to heat goods which have been placed in the autoclave so that it reaches sterilising temperature, whereby the feeding of heat between the areas is controlled. Such control is effected by successive registration of the temperatures in the areas and when the temperatures differ between the areas, the feeding of steam to the area which temporarily has a higher temperature is ceased, and as soon as the temperature in the adjacent area has passed the last mentioned temperature, the feeding of steam to that same area is resumed. In a device for the carrying out of the method, a temperature meter is arranged in each area.

  • Publication number: 20020001535
    Abstract: A rotary sterilization system, a controller for use in the rotary sterilization system, and a method performed by the controller are disclosed. The system, controller, and method are used to administer a sterilization process performed on a line of containers and provide on-line handling of a deviation in a scheduled parameter during the process. The containers contain a shelf stable food product that is to be sterilized in the sterilization process. In addition to the controller, the rotary sterilization system includes a rotary sterilizer. The controller controls the rotary sterilizer in performing the sterilization process according to scheduled parameters. When a deviation in a specific one of the scheduled parameters occurs, the controller identifies those of the containers that will in response have a total lethality predicted to be delivered to them during the sterilization process that is less than a predefined target lethality.

  • Publication number: 20010055550
    Abstract: A catalyst (17) of a NOx absorbing-and-reducing type is disposed in an exhaust passage (10) of an engine (1). The catalyst (17) absorbs a NOx component in an exhaust gas under an over-oxygen atmosphere and reductively emits the absorbed NOx component according to reduction of oxygen concentration. A control unit (20) of the engine (1) estimates a momentary amount of the absorbed NOx component, and further estimates an integrated amount of the absorbed NOx component according to the integration of the momentary amounts. Then the control unit (20) lets the catalyst (17) to emit the NOx component when the integrated amount is equal to or greater than a predetermined absorption amount. In addition, the control unit (20) corrects the momentary amount to a smaller value in adverse proportion to the increase in the integrated amount.

  • Patent number: 6332901
    Abstract: A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.

  • Publication number: 20010053338
    Abstract: An improved polyamidation system and control system for producing a polyamide from molten dicarboxylic acid monomer and molten diamine monomer. The polyamidation control system measures the molar ratio of the molten dicarboxylic acid monomer and molten diamine monomer with a partially polymerized mixture. A feed forward control algorithm is employed within the control system to determine the extent to which the ratio of the initial reactants must be altered prior to mixing in order to produce the resulting polyamide having stoichiometrically balanced molar ratio.

  • Publication number: 20010047622
    Abstract: A control apparatus for a reformer and a method of controlling the reformer are provided. The reformer gasifies a reformate fuel by a reforming reaction, supplies the obtained reformate gas to an energy converter to convert the reformate gas into energy of another form, and heats the reformate fuel by burning emission containing unreacted flammable gas produced in the energy converter. The control apparatus comprises a reforming amount assessing device for assessing the amount of the reformate fuel to be gasified, and an emission amount assessing device for assessing the amount of emission to be supplied into the reformer on the basis of the assessed amount of reformate fuel. When using the unreacted hydrogen gas generated in a fuel cell for heating the reformate fuel, the unreacted hydrogen gas and combustion aid gas can be controlled so that the reformate fuel is heated properly.

  • Patent number: 6290913
    Abstract: The structure of the present invention consumes carbon monoxide produced by the reverse shift reaction proceeding in an effective temperature range that ensures a sufficient activity of a catalyst for selective oxidation of carbon monoxide, thus significantly reducing the concentration of carbon monoxide included in a resulting hydrogen-rich gas. A fuel reformer 30 incorporated in a fuel-cells system 10 includes a gas flow sensor 37 disposed in a reformed gas supply conduit 36 that connects a reformer unit 32 with a CO selective oxidizing unit 34. A control unit 70 outputs driving signals to three valves of the CO selective oxidizing unit 34, in response to a detection signal from the gas flow sensor 37. The CO selective oxidizing unit 34 has three reaction chambers filled with a carbon monoxide selective oxidizing catalyst. The number of the reaction chambers, which a reformed gas fed to the CO selective oxidizing unit 34 passes through, is changed by switching the on/off state of the three valves.
