  • Patent number: 7278597
    Abstract: A rotating cylindrical flailing vegetation cutter, which includes a power rotated shaft having a cross-sectional profile. Disks are provided having a central aperture adapted to slide over the shaft and non-rotatably engage the cross-sectional profile. Each of the disks remain separate from and unattached to the shaft. Spacers are secured between the disks to maintain relative lateral spacing of the disks and form a disk assembly. Flail members are carried by the disk assembly.

  • Publication number: 20060240369
    Abstract: A waste heat recovery system is coupled to a flare or exhaust stack of, for example, a landfill gas treatment system, to recover at least a portion of the energy within the exhaust produced by the gas treatment system and provides the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process. For indirect transfer of energy the waste heat recovery system includes a transfer pipe connected between the exhaust stack of a primary process and a heat exchange unit while an induction fan connected to the transfer pipe operates to create a draft within the transfer pipe to facilitate movement of some of the exhaust gas from the exhaust stack of the primary process to the heat exchange unit.

  • Publication number: 20060240368
    Abstract: A bustle for use on a flare or an exhaust stack of, for example, a landfill gas treatment system, efficiently transfers gas from the stack to a waste heat recovery system associated with the landfill gas treatment system without substantially affecting the operation of the landfill gas treatment process. The bustle enables the heat recovery system to recover at least a portion of the energy within the exhaust produced by the gas treatment system and to provide the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process.

  • Publication number: 20060179982
    Abstract: A portable sawmill with bidirectional cutting circular saws includes a saw support pivotally mounted to a primary support structure for pivotal movement about a pivot axis which is transverse to the direction of movement. Two circular saws are rotatably mounted one above the other on the saw support. A first one of the two circular saws rotates in a first rotational direction and a second one of the two circular saws rotates in a second rotational direction. The teeth on both of the two circular saws are always moving toward a log resting on the log support as the log is being cut. An actuator is provided for selectively pivoting the saw support to invert the positioning of the two circular saws so that the teeth on both of the two circular saws continue to move toward the log being cut upon a change in direction occurring.

  • Patent number: 7017631
    Abstract: A feller buncher includes an elongate support having an axis, a first side, a second side, a first end and a second end. A first tree receiving cavity is positioned along the first side of the support. A second tree receiving cavity is positioned along the second side of the support. A circular saw is positioned at the second end of the support. The plane of the saw is transverse to the axis of the vertical support. Movable grapple arms are positioned on each of the first side and the second side of the support above the circular saw. The grapple arms are adapted to hold trees while they are being felled and then maintain bunches of felled trees in each of the first tree receiving cavity and the second tree receiving cavity.

  • Publication number: 20050130083
    Abstract: This invention relates to a silver halide photographic element comprising a support bearing a cyan dye image forming unit comprised of at least one red sensitive silver halide emulsion, a magenta dye image forming unit comprised of at least one green sensitive silver halide emulsion, and a yellow dye image forming unit comprised of at least one blue sensitive silver halide emulsion; wherein the at least one green sensitive silver halide emulsion comprises two absorptance peaks, the first peak being between 515 and 540 nm (short wavelength peak) and the second peak being between 565 and 590 nm, (long wavelength peak) and wherein (a) the ratio of the absorptance peak value of the short wavelength peak to the absorptance peak value of the long wavelength peak is from 0.65 to 1.55; (b) the absorptance minimum between the two absorptance peaks is between 530 and 560 nm; (c) the ratio of the absorptance value at the absorptance minimum to that of the smaller absorptance peak is 0.
