Abstract: A blowout preventer includes a main body having a through bore and defining a passage transverse to the through bore. A seal is disposed in the main body and arranged to restrict fluid flow from the through bore to the passage. The seal comprises a seal body formed as a closed loop having an upper surface and a lower surface, wherein the seal body comprises an inner wall and an outer wall. The lower surface comprises at least one wing extending laterally from the outer surface to provide a lateral sealing surface. The upper surface comprises at least one raised portion to provide a sealing surface.

Abstract: A container such as a barrel or drum is provided for processing of solid material or parts with a liquid. The container is designed with grooves leading to holes or slots in the side that draw liquid into the container due to the rotation of the container when it is immersed in a tank of liquid. The holes or slots have a small dimension in the direction of rotation to minimize the probability of solid material coming out of the container. The fluid flow caused by the rotation serves to increase the rate of solution replacement inside the container as well as to keep the solid material from falling out through the holes or slots. The container disclosed is useful in processes in the plating, etching, leaching, and surface finishing industries.

Abstract: Systems and methods are provided for allowing users to safely and efficiently conduct repeatable dynamic experiments involving coordinated applications of force, motion, pressure, temperature, flow, dispersion and other physical events via a testing fixture positioned within an imaging environment.

Abstract: A strength machine includes a housing having at least two openable or detachable housing shells, a support structure coupled to the housing, a rotatable flywheel mounted on a shaft supported by the support structure, the flywheel being situated between the two housing shells, the flywheel changing its direction of rotation while in operation, a strap- or belt-shaped flexible pulling element attached to the shaft, a hand grip which forms part of or is attached to the flexible pulling element, and an attachment module coupled to the housing, for securing the strength-training machine to an external support.

Abstract: Pressure Delivered 3D Dynamic Printing (PD3DP) comprise 3D printing wherein the polymerizable material (typically a resin) is delivered under positive pressure as each layer of a target object is built/printed. Such positive pressure can be applied intermittently and even reversed to provide a cyclical application of the pressure to assist delivery of the resin, placement of the resin at locations suitable for the shape of the target object, curing of the resin, and releasing of the target object from the projection place between printing of successive layers.

Abstract: A method for electrokinetic dewatering of slurries, consisting of parallel electrode pairs suspended in a slurry deposit. Deployment consists of pulling the ends of electrode sections across a deposit. If solar power is used, floating solar panels are connected to electrodes at fixed spacings and deployed concurrently with the electrode assembly. The electrodes are suspended below or above the mudline by floats. By inflating or deflating the floats, the electrode positions are remotely controlled. External sleeves on the electrodes are used to trap and vent gas generated at the electrodes that otherwise might prematurely terminate the dewatering process. An insulated supplementary conductor is intermittently connected to the anode to decrease power attenuation and mitigate the risk of anode failure. Grid power is regulated by a central control system at the edge of a deposit. Solar power is regulated by dispersed control systems on the floating solar panels.

Abstract: The present document related to the processing of mining materials, such as ores, rocks, minerals, and aggregate materials to separate valuable components. There is provided a process and system for extracting a valuable component from a mining feedstock comprising geological materials. The process can comprise subjecting the mining feedstock to a kinetic pulverization stage wherein the mining feedstock is subjected to self-collisions created by vortices within the kinetic pulverizer to produce a pulverized material; admixing the mining feedstock or the pulverized material with a chemical additive configured to selectively liberate the valuable component from the geological material; and subjecting the pulverized material to an extraction stage to produce a valuable component-rich stream and a valuable component-depleted stream.
