Abstract: A test apparatus can measuring particle plugging of a simulated fracture. The test apparatus can include a first test component having a first surface and a second test component having a second surface. The second test component can be positionable relative to the first test component to create a simulated fracture between the first surface and the second surface. The test apparatus can include a visualization area of at least one of the first test component or the second test component can be positioned between a fluid inlet and a fluid outlet along at least a portion of the simulated fracture.

Abstract: Heating apparatus and methods for thermally processing a part including improved control of temperature. A thermal management system is coupled to a back surface of a table thermally coupled to an inductive heating circuit. The thermal management system includes a chamber defining an interior space, at least one cooling fin disposed within the chamber, an inlet extending through the chamber and fluidly communicating with the interior space, and an outlet extending through the chamber and fluidly communicating with the interior space. In some applications, an air source fluidly communicates with the inlet and is selectively operable to generate an air flow through the chamber, so that the thermal management system may be selectively operated in an insulator mode and a cooling mode.

Abstract: Facilities and processes for generating ethanol from municipal solid waste (MSW) in an economical way via generating a syngas, passing the syngas through a catalytic synthesis reactor, separating fuel grade ethanol, extracting energy at particular strategic points, and recycling undesired byproducts.

Abstract: A battery cell terminal quick connect clamp for attaching to a battery cell terminal has a conductive contact coupled to a connecting element to which a connector attached to the end of a battery monitoring lead can attach. The quick connect clamp includes a clamping mechanism that when in a clamped position presses the conductive contact against a side of the battery cell terminal.

Abstract: Membrane roofs are susceptible to damage in high winds. Wind can lift a membrane roof from a building and cause it to tear or become damaged. The present roof vent prevents liftoff and damage by reducing the air pressure under the membrane during high winds. The present roof vent has two opposed convex domes separated by a gap. Wind blowing across the roof flows between the domes where it accelerates and creates a region of low pressure according to the Venturi effect. The lower dome has an opening at the gap so that the low pressure is applied to the space under the membrane roof. Therefore, when wind blows across the roof, the vent draws air from under the membrane and the membrane is pressed against the roof, preventing liftoff.
