5340021 AIR CONDITIONING DEVICE VEHICLES
FOR
Kajino Yuuichi; Sugi Hikaru; Ban Koichi; Honda Yuuji; Samukawa Katsuhiko; Kawai Takayoshi Nippondenso Co Ltd The object of the present invention is to supply air to passengers in an automobile so that they will feel more comfortable in the presence of solar radiation by suppressing a rise in temperature in a vehicle passenger compartment caused by solar radiation. There is provided a cold air damper which feeds cold air immediately after an evaporator to a face blow port and mixes it with the conditioned air that has passed through an air mixing damper, with the amount of blown air is changed by a blower fan. A control means detects the amount of solar radiation present by using a solar radiation sensor. This invention calculates the temperature of air blown out in the absence of solar radiation, calculates the temperature of air blown out in the presence of solar radiation, calculates a corrected blowing rate according to a thermal equilibrium equation in the presence of solar radiation, and calculates a blowing rate in the presence of solar radiation.
5340547 CLEAR LIQUOR SCRUBBING MAGNESIUM-ENHANCED LIME FLUE GAS DESULFURIZATION SYSTEM Moser Robert; Wilhelm James H; Burke John; Gray Sterling Electric Power Research Institute An improved magnesium-enhanced lime flue gas desulfurization system is provided which produces the high sulfur dioxide removal level of previous magnesium-enhanced lime flue gas desulfurization systems and additionally produce waste solids that have significantly better properties and are more easily dewatered than the solids produced by known systems. The magnesium-enhanced lime flue gas desulfurization system of the present invention includes a crystallizer-clarifier reaction tank (CCRT) which receives scrubber effluent and functions as a combined reaction tank and thickener. Clear liquor from the CCRT is sent to a scrubber to scrub the flue gas, and a portion of the CCRT-thickened solids are directed to a high pH
premix slurry tank (PMST) where the crystallization environment can be controlled by reagent addition and pH. The PMST contents are circulated to the CCRT and are separated to produce a waste solids fraction that is easily dewatered. A fines removal system may also be employed to reduce the presence of fine solids and promote large crystal solids.
5340746 COMPOSITE REACTIVE ARTICLES FOR THE DETERMINATION OF CYANIDE Hagen Donald F; Haddad Louis C; Perkins Robert E; Markell Craig G Minnesota Mining and Manufacturing Company Composite reactive articles are useful for quantifying cyanide ions in solution. The composite reactive articles can be porous reactive supports comprising an inert substrate having immobilized thereon finely divided gold. The porous reactive supports can be particulate, porous fibrous membranes, or solution-cast membranes. Alternatively, the composite reactive articles can comprise porous fibrous membranes having enmeshed therein the aforementioned porous supports which can be in particulate or fibrous forms. The method for quantifying cyanide ions in solution comprising the steps of contacting and passing a solution containing cyanide ions through a reactive support comprising a porous, high surface area, inert substrate on which is immobilized finely divided elemental gold at a controlled rate to provide for a time to provide sufficient contact time for the gold and cyanide ions to react and provide a soluble gold cyanide complex, recovering the effluent comprising said gold cyanide complex, and determining the quantity of cyanide present in the gold cyanide complex.

New Patents A method and apparatus are disclosed for conducting a physical process and a chemical reaction by exposing a material containing a volatile substance to microwave radiation where the morphology of said material will change when exposed to such radiation. The power of said radiation is adjusted over time as the morphology of the material changes to maximize the effect of the radiation in order to produce a product in a minimum amount of time that is substantially free of said volatile substance. The method and apparatus can also be used to conduct such a process or reaction with materials that do not contain a volatile material. In one embodiment a method and apparatus are disclosed for manufacturing a polyimide from a precursor in a solvent by exposing the precursor to microwave radiation in a tuneable microwave resonant cavity that is tuned during imidization to achieve critical coupling of the system. Microwave power is controlled to remove the solvent and obtain the desired level of reaction. Processing time has been reduced thirty fold as compared to conventional thermal methods.
5345479 SENSITIVITY ENHANCEMENT FOR AIRBORNE RADIOACTIVITY MONITORING SYSTEM TO DETECT REACTOR COOLANT LEAKS Graham Kingsley, Murrysville, PA, UNITED STATES Westinghouse Electric Corporation A method and apparatus for measuring radioactivity associated with nuclear reactor coolant leaks. The method includes providing a delay tank in a gas sampling line upstream of a radiation particlllnte monitor, the delay tank allowing radioactive noble gases from the leak to decay to radioactive daughter particulates that are monitored by the radiation particulate monitor. The apparatus includes the delay tank as well as a background delay tank and a valve sequencer for comparing radiation associated with the delay tank to radiation associated with the background delay timk.

To measure water vapor and carbon dioxide, a gas analyzer includes a light source, a reference flow cell, a sample flow cell, a detector and a source of gas. The light source, flow cells and detector are arranged so that the detector detects light transmitted from said light source through the flow cells. The flow cells have folded paths for the light. A reference signal is subtracted from a sample sigmal to obtain an independant variable. Carbon dioxide and air mixed with carbon dioxide are supplied as required. The carbon dioxide is supplied from a container through capillary tubes. Heat is applied to the tubes to control the flow rate. A signal representing gross concentration of the carbon dioxide as a dependant variable is obtained from said independent variable from an empirically determined polynomial.
