Abstract: A fiber spreader is provided which reduces fiber damage that occurs duringpreading. The fiber spreader includes a thin electrically grounded support sheet for supporting a layer of fibers on one surface thereof. The fibers supported on the support sheet are guided by a plurality of guide rollers past at least one corona discharge region at which the fibers are spread substantially uniformly. A motor driven spool advances the support sheet past the corona discharge region. The fibers are attached to the support sheet by an electrostatic attraction. The guide rollers are positioned so as to provide at least one region in which the sheet and the fibers are physically separated to allow for the uniform spreading of the fibers. After the fibers are spread, the fibers and the support sheet are united again and collected on a motor-driven spool.

Abstract: An in-situ thermal desorption system which combines thermal desorption and vacuum extraction to separate organic compounds from in place contaminated soils is disclosed. A "heating blanket" desorption unit is applied directly to the surface of the hydrocarbon contaminated soil. The heating blanket assembly comprises of four basic components: a surface heating element, a thermal insulating mat, a vacuum collection system, and a vapor barrier. The surface heater, when energized, initiates a thermal front which moves down through the soil by thermal diffusion. As the soil is heated, organic compounds and water vapor are desorbed and removed from the soil matrix. A vapor collection system including a blower is fitted to the vapor barrier to establish a slight negative pressure inside the modular heating blanket units. The vacuum created by the in-line blower in the collection system sweeps clean air through and/or from the heat treated soil which purges volatile organic compounds (VOC), water, and other gases from the soil pores and sweeps in air from surrounding soils which is used to oxidize organics in the influent, within the heating elements, and within a thermal oxidizer. The off-gas is contained by the vapor barrier and collected via the blower. Air pollution control equipment is used to treat the off-gas, as necessary, to satisfy air emissions requirements.

Abstract: A sweep generator 230 applies a range of frequencies to an rf coil 140 to detect the resonant frequency of a field generated by a magnet 125a,b. A frequency to current converter 220 applies an auxiliary magnetic field to tune an MRI apparatus to the resonant frequency of the rf coil. A flexible coil of one turn (300) or two or more turns (500) has a plurality of segments (301-307; 501-513). One of the belt has a contact k0, (k0′), which is electrically connectable to one or more contacts k1, (k1′), k2, (k2′), etc. located between the ends of the segments. For each connection to successive contacts, the length of the coil and its inductance increases by the added impedance DLij between contacts ki and kj. That increase of inductance is nullified by capacitors DCsij located between segments.
