Patent number: 7396389Abstract: Unless an abnormality exists in piping introducing a pressure from front and rear of DPF 22 into a differential pressure sensor 45, pulsations of pressure propagation through an exhaust passage 21 is offset in a detection value of a pressure difference of the differential pressure sensor 45, and an amplitude of the detection value of the DPF pressure difference resulting from pulsation of the pressure becomes small. If a crack exists in one of the piping 3a and 3b, the influence of a pulsation of the pressure appears in the DPF pressure difference and the amplitude of the detection value of the DPF pressure difference becomes large. The amplitude of the detection value of the DPF pressure difference is compared with the reference value and is detected as being abnormal when it is large, utilizing the phenomenon described above.Type: GrantFiled: February 9, 2005Date of Patent: July 8, 2008Assignee: Denso CorporationInventors: Yasuhiro Kariya, Tsukasa Kuboshima

Patent number: 7396393Abstract: An antiallergen filter of the present invention is characterized in that a water-insoluble high-molecular weight anti-allergenic agent having a phenolic hydroxyl group and a moisture-absorbing material are carried on a filter.

Patent number: 7396433Abstract: The process separates oil and water from a sludge mixture by directing the sludge mixture into a rapidly rotating friction dryer having a cylindrical chamber with a smooth inner surface and a rotating rotor having rotor arms extending into closely spaced relation to the inner surface of the chamber. The rotor is rapidly rotated to form an annular bed of the sludge material while moving the material particles in the mixture axially and tangentially and while frictionally generating heat between the rotor arms and the sludge material sufficient to evaporate the water in the sludge material to steam. At the same time, the oil in the mixture is heated by the steam and evaporated at a temperature below the normal atmospheric boiling point of the oil. Thereafter, the separated evaporated oil and the steam are removed from the chamber.Type: GrantFiled: May 16, 2002Date of Patent: July 8, 2008Assignee: Thermtech ASInventor: Asbjørn Strand

Patent number: 7396434Abstract: A continuous and batch system to produce cellulose, native lignin and unicellular protein from any form of vegetation in a closed process. The biomass is mixed in the impregnate solution of nitric acid and/or ammonium hydroxide and water. After a period of time at room temperature and atmospheric pressure the chemical solution is recycled. The biomass is moved to the reactor and heated. Evaporated impregnate is recovered via absorption tower and recycled back to chemical solution. The biomass is moved to an alkaline solution, then cooled to separate pulp from black liquor. The black liquor is pumped to a separation tank and is treated to precipitate lignin. The solution is filtered to separate sweet liquor and lignin. The lignin is dried and the sweet liquor is fermented to produce unicellular protein.Type: GrantFiled: June 3, 2004Date of Patent: July 8, 2008Inventors: Jose Antonio Rodriguez Rivera, Kelly Anthony O'Flynn

Patent number: 7396435Abstract: Methods for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. Methods for producing a consistent flow rate of pulp, and, for producing uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. A method includes introducing a dewatered pulp to a rotating shaftless screw conveyor. The pulp is deposited from the screw conveyor onto a moving belt conveyor through a chute. The pulp is leveled with a rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer.Type: GrantFiled: September 29, 2003Date of Patent: July 8, 2008Assignee: Weyerhaeuser Co.Inventors: Ramon C.
