  • Publication number: 20130244284
    Abstract: Solid biomass having a moisture content in a range of 30 to 95 mass % is brought into contact with ammonia gas at a pressure in a range of 0.5 to 4 MPa and held at 50 to 200 degrees C. Subsequently, the solid biomass is rapidly decompressed to be blasted. The ammonia gas evaporated by decompression is recovered and recycled. The ammonia gas can be brought into contact with the entire solid biomass evenly and in a short time. Since absorption heat of the ammonia gas is generated, energy consumption required for additional heating can be reduced.

  • Patent number: 4961345
    Abstract: The apparatus of the present invention detects the resonant frequency of a vibratory member in contact with the fluid in order to determine the density or pressure of the fluid. The vibratory member is disposed in a housing to form a cavity with no flow communication between the side of the vibratory member facing into the cavity and the other side of the vibratory member. The vibratory member is vibrated by an annular piezoelectric device which may be attached to one or both sides of the vibratory member. An amplifier and feedback circuit regulate the frequency of oscillation of the piezoelectric device to that of the resonant frequency. The piezoelectric device may be comprised of several separate sections or several sections with partial interruptions in the piezoelectric material. Instead of the vibratory member and the piezoelectric transducer combination, the vibratory member may be constructed from a single fixed piezoelectric device with another piezoelectric disc mounted thereon.
