Patent number: 6171020Abstract: A pressure adjustable, soil-cleating attachment for front of bulldozers, designed for erosion control by cleating the ground in the area between the bull dozer tracks, thus facilitating one pass cleating of the entire area under the bull dozer. The present invention may also be used to crimp straw and when reseeding land. A cleated roller is connected to two support arms, which releasably mount to the bottom of the bulldozer push arms. A protective shield is connected to each support arm, and covers the upper visible portion of the roller as the roller rotates, thereby reducing flying debris during cleating of the ground. Roller stabilization arms are designed to compensate for movement of the support arms as the bottom of the bulldozer blade wears during use.Type: GrantFiled: December 4, 1998Date of Patent: January 9, 2001Inventors: Dan Pikna, Rick Reidl

Patent number: 6045295Abstract: In the operation of a landfill compactor, it is a common problem for the wheels to pick up debris, especially wire and cable, and carry it around with the wheels as they rotate. When the debris falls from the wheels in the direction toward the frame and the axles, it becomes packed between the frame and the axle hampering machine operation and requiring hours of corrective maintenance. The apparatus of the subject invention for inhibiting the wrapping of debris about the axle assembly provides a hook member to ensnare debris. As the wheel rotates, the debris picked up by the hook member is dragged across a serrated blade portion mounted on the axle assembly to pull apart the debris and thus prevent the debris from wrapping around the axle assembly.Type: GrantFiled: December 17, 1998Date of Patent: April 4, 2000Assignee: Caterpillar Inc.Inventor: John E. Puchosic

Patent number: 5857810Abstract: A chemical barrier is formed by injecting a suspension of solid particles or colloids into the subsurface. First, a stable colloid suspension is made including a surfactant and a non-Newtonian fluid. This stable colloid suspension is characterized by colloid concentration, colloid size, colloid material, solution ionic strength, and chemical composition. A second step involves injecting the optimized stable colloid suspension at a sufficiently high flow rate to move the colloids through the subsurface sediment, but not at such a high rate so as to induce resuspending indigenous soil particles in the aquifer. While injecting the stable colloid suspension, a withdrawal well may be used to draw the injected colloids in a direction perpendicular to the flow path of a contaminant plume. The withdrawal well, may then be used as an injection well, and a third well, in line with the first two wells, may then be used as a withdrawal well, thereby increasing the length of the colloid barrier.Type: GrantFiled: February 27, 1997Date of Patent: January 12, 1999Assignee: Battelle Memorial InstituteInventors: Kirk J.

Patent number: 4749452Abstract: A unitary membrane-electrode assembly includes an electrode structure with multiple layers having different overvoltages for the desired electrochemical reaction. In the preferred arrangement the layer attached to the membrane has the higher overvoltage thereby preferentially locating the reaction zone a small but controlled distance away from the electrode membraneinterface. In a NaCl brine electrolysis process the use of a dual layer electrode as the cathode is particularly useful because it eliminates formation of concentrated caustic at the membrane surface. As a result, back migration of OH.sup.- ions is reduced and cathodic current efficiency is increased.Type: GrantFiled: December 30, 1981Date of Patent: June 7, 1988Assignee: Oronzio de Nora Impianti Elettrochimici S.p.A.Inventors: Anthony B.
