Abstract: The invention encompasses systems and methods that allow a clinician who is untrained in the art of electroencephalography to insert and functionalize unitized intracranial electrode arrays at the bedside that, by specific design, position ground and reference electrodes in electrically “quiet” locations to record durable, high-fidelity intracortical EEG.

Abstract: Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid.

Abstract: A nozzle for discharging first and second fluids in a spray pattern into a vessel, such as oil and steam in a catalytic cracking unit, includes various configurations for preventing erosion of the outlet portion of the nozzle that otherwise might be due, for example, to contact with a catalyst or other predetermined substance. In one such nozzle, the exterior surface of the outlet portion substantially conforms to the internal contour of the vessel. In another such nozzle, the outlet portion defines a plurality of substantially concentric, substantially elliptical-shaped outlet apertures. In another nozzle, the outlet portion is formed of ceramic and is connected to the inlet portion by a metal connector.

Abstract: A spray nozzle includes a body defining an inlet chamber and an outlet. An orifice disk, adjacent the outlet, has opposing surfaces, an inner sidewall extending between the opposing surfaces which defines an orifice, and a peripheral sidewall extending between the opposing surfaces for centering the orifice disk within the inlet chamber. A swirl disk, adjacent to the orifice disk, has opposing surfaces and a sidewall extending between the opposing surfaces. The sidewall of the swirl disk forms a periphery for centering the swirl disk, a hollow for creating a vortex adjacent to the orifice and an inlet for channeling fluid from the periphery to the hollow. A plug is fixed within the inlet chamber of the body for retaining the orifice and swirl disks as well as defining an annulus area in fluid communication with the inlet of the swirl disk.
