  • Patent number: 6192672
    Abstract: A fuel vapor purging method controls fuel vapor purging during stratified operation. Several factors influence vapor purge control, including fuel vapor concentration in the cylinder and temperature of the emission control device. The fuel vapor passes through the cylinder unburned by maintaining the concentration within allowable limits. The unburned fuel vapor reacts exothermically in the emission control device thereby generating heat. To guarantee that the fuel vapor reacts in the first emission control device, the fuel vapor purge is restricted to a certain temperature range. To guarantee that the fuel vapor does not burn in the cylinder, the concentration is kept to a restricted value.

  • Patent number: 6192675
    Abstract: In an exhaust gas purification device, a catalytic converter containing selective reduction catalysts is disposed in an exhaust gas passage of an internal combustion engine capable of being operated at a lean air-fuel ratio. The catalytic converter includes a plurality of the selective reduction catalysts disposed in series in the casing of the catalytic converter. Bypass passages which supply the exhaust gas to downstream selective reduction catalysts in the casing by bypassing the upstream catalysts are provided. When a reducing agent is supplied to the exhaust gas upstream of the converter, a part of the supplied reducing agent directly reaches the downstream selective reduction catalyst through the bypass passages without being oxidized by the upstream selective reduction catalysts. Therefore, the NOx purifying abilities of the downstream catalysts are improved and the formation of sulfates on the downstream catalysts is suppressed.

  • Patent number: 6192678
    Abstract: A secondary air supply control system controls supply of air to a catalyst arranged in the exhaust passage of an internal combustion, for purification of exhaust gases. A temperature difference between a temperature of an engine coolant sensed at a stoppage of the engine and stored and a temperature of the engine coolant sensed at a start of the engine after the stoppage is calculated. It is determined whether or not a stop time period between the stoppage and the start of the engine is short, depending on the temperature difference. When it is determined that the stop time period is short, an operation time period over which the air pump is to be operated to supply air to the catalyst is corrected based on a temperature difference between a temperature of the engine coolant sensed at the start of the engine and a temperature of intake air sensed at the start of the engine.

  • Patent number: 6192679
    Abstract: A first and second converter are connected via an exhaust passage so that the first converter is situated further upstream relative to the flow of exhaust. These converters comprise an adsorbent which adsorbs hydrocarbons at a temperature lower than a first temperature and discharges hydrocarbons at a temperature higher than the first temperature, and a catalyst which oxidizes hydrocarbons when a second temperature higher than the first temperature is exceeded. The heat capacity of the exhaust passage is set so that the temperature of the adsorbent of the second converter does not reach the first temperature before the catalyst of the first converter reaches the second temperature. By repeating this hydrocarbon adsorption/oxidation, the hydrocarbon discharge amount is reduced especially during a cold start of the engine.

  • Patent number: 6192687
    Abstract: Uninterruptible power supplies are provided that utilize a material to provide a source of thermal energy that may be converted to electrical energy to produce backup electrical power for a load. In some embodiments, a hot tank assembly is utilized to hold a liquid heated to a predetermined temperature. A closed-loop pipe containing, water for example, is immersed in the heated liquid. Upon the loss of primary power, the water flows into the heat exchanger where it is raised above its boiling temperature. The steam is then passed to a heat engine (e.g., a turbine-based system) that converts the heated steam to mechanical energy by causing the heat engine rotor to rotate. A generator is physically coupled to the heat engine so that the rotation of the heat engine rotor drives the generator. The generator produces AC power which is converted to DC and again back to AC before being provided to the load. In other embodiments, a solid mass, such as a block of iron, is heated to a predetermined temperature.

  • Patent number: 6192696
    Abstract: In a refrigerating apparatus using a non-azeotropic refrigerant, the composition is included among the quantities of state of a refrigerant, so that it is difficult to detect the state of the interior of the refrigerant circuit. For this reason, it is difficult to stabilize the operation of the refrigerating apparatus by detecting the state of the interior of the refrigerating apparatus, and avoid the malfunction of the refrigerating apparatus. The cyclic composition of the refrigerating apparatus is detected, and the state of the interior of the refrigerating apparatus is detected accurately by using this cyclic composition. In addition, the refrigerating apparatus is arranged such that in a case where there is a quantity of state which cannot be detected accurately owing to an error or the like of the detected cyclic composition, that value can be detected directly. As a result, it is possible to accurately detect the malfunction of the refrigerating apparatus and avoid this state.

  • Patent number: 6192705
    Abstract: A process is disclosed for reliquefying boil-off gas produced by pressurized liquid natural gas. In this process, refrigeration duty is provided to a heat exchanger by means of a refrigeration cycle. Pressurized natural gas is cooled by the heat exchanger and then expanded to a lower pressure to produce a liquid stream that is passed to a first phase separator. A boil-off vapor is passed through the heat exchanger and it is then compressed and cooled before being recycled back through the heat exchanger. The compressed, cooled boil-off gas is then expanded and passed to a second phase separator. A vapor stream produced by the second separator is removed from the process. A liquid stream produced by the second phase separator is passed to the first phase separator to produce a pressurized liquid having a temperature above about −112° C. and a pressure sufficient for the liquid to be at or below its bubble point.

  • Patent number: 6192711
    Abstract: A device for transporting and cooling hot glass panes (10) has a support wall (1) in which there are alternatingly stationary support ribs (3) and between two support ribs (3) at a time there are hollow chambers (4) with wall parts (11) which are adjustable in the direction perpendicular to the glass pane (10). In the transport of a glass pane (10) the movable wall parts (11) are aligned essentially flush with the free edges (5) of the support ribs (3). When a glass pane (10) is being transported the hollow chambers (4) are exposed to hot air such that between the glass pane (10) and the support wall (1) for the wall parts (11) pushed towards the glass pane (10) a thin gas cushion (“L”) of hot air forms. When a glass pane (10) is being quenched the movable wall parts (11) are moved back to a greater distance from the glass pane (10). For quenching of a glass pane (10) cold air is blown out of the support ribs (3) in the wall parts (11) which are moved back relative to the glass pane (10).

  • Patent number: 6192712
    Abstract: A method for fabricating an optical waveguide, comprising the following steps. That is, forming an optical waveguide on surface of a substrate via an atmospheric pressure chemical vapor deposition (AP-CVD) method using a silica raw material containing an organic material, and irradiating ultraviolet light on at least a portion of that optical waveguide. The refractive index of the portion of the optical waveguide irradiated with ultraviolet light increases. Since changing the refractive index in this way enables the formation of a diffraction grating, it is possible to manufacture optical filters and wavelength dispersion devices.

  • Patent number: 6192713
    Abstract: A method and apparatus is disclosed for the manufacture of an optical fiber preform having incorporated therein a comparatively high concentration of rare earth dopant material, and which thus can be drawn and processed into an optical fiber having low numerical aperture, low core attenuation, and high pumping power absorption. The high concentrations of rare earth dopant material are accomplished through either the “hybrid vapor processing” (HVP) method or a “hybrid liquid processing” (HLP) method, each capable of being practiced in combination or independently of one another. The HVP method involves the vaporization of a rare earth halogen by the exposure thereof to a sufficiently elevated temperature, independently, or contemporaneously with the transport of the resultant rare earth halogen laden vapor, into a glass forming oxidation reaction zone on a flowing stream of essentially an unreactive inert gas, such as helium.
