    摘要: A method for preparing a ruthenium carbene complex precursor includes reacting a ruthenium refinery salt with a hydrogen halide to form a ruthenium intermediate, and reacting the ruthenium intermediate with an L-type ligand to form the ruthenium carbene complex precursor. A method for preparing a ruthenium vinylcarbene complex includes converting a ruthenium carbene complex precursor into a ruthenium hydrido halide complex, and reacting the ruthenium hydrido halide complex with a propargyl halide to form the ruthenium vinylcarbene complex. A method for preparing a ruthenium carbene complex includes converting a ruthenium carbene complex precursor into a ruthenium carbene complex having a structure (PR1R2R3)2Cl2Ru═CH—R4, wherein R1, R2, R3, and R4 are alike or different, and wherein covalent bonds may optionally exist between two or more of R1, R2, and R3.

    摘要: High-pressure electrokinetic (“EK”) pumps comprising a hybrid monolith provide a high surface charge density and a continuous stable skeleton morphology with micrometer-sized through-pores. The hybrid monolith of the subject invention has superior mechanical strength and better stability in comparison to prior art monoliths with equivalent mechanical stability. The surface charge of the hybrid monolith can be modified and/or made stable by the use of different chemical reagents. The chemical reagents and resulting modification to the monolith serves to expand the usefulness of the hybrid monolith to a variety of pumping applications including chip-based systems and other applications where the ability to pump an acidic solution is required.

    摘要: A screening machine on a frame with a hopper having a conveyor belt. The conveyor belt discharges particulate material poured into the hopper into a rotating barrel screen or vibrating planar screen for sifting the material. A hammermill apparatus is pivotably mounted on a hood member to an arm that is pivotably mounted to the frame of the machine. The hammermill is positioned above the conveyor belt at the discharge end. The hammermill can pivot upwardly relative to the arm upon striking a large object on the conveyor belt, and a spring mounted to the arm and the hood biases the hammermill back to its original position. A hydraulic ram is drivingly linked to the arm for manually or automatically displacing the hammermill relative to the conveyor belt.
