Abstract: Machine learning-based part selection in relation to one or more end use environmental conditions is provided. The process includes training a machine learning model to facilitate evaluation of a part for use in a product based on an environmental condition. Further, the process includes receiving measurement data for the part, and establishing a score for the part by comparing the measurement data for the part to a specification for the part. In addition, the method includes using the machine learning model and the established score for the part in determining whether to use the part in the product based on the environmental condition.

Abstract: The invention provides new systems/methods for providing oxygen to chronically ill patients, such as COPD patients, through a more efficient portable oxygen concentrator (“POC”) that at least sometimes delivers an enriched airflow having a significantly lower overall oxygen concentration than that administered by typical POCs. In aspects, the methods/systems of the present invention are configured to automatically switch from pulse delivery to continuous delivery, from continuous delivery to pulse delivery, or any combination thereof, at least once per day, when certain conditions occur. Methods/system can comprise the ability to switch between mode(s) comprising delivery of a moderately enriched oxygen airflow (MEOA) and mode(s) comprising delivery of intensively enriched oxygen airflow, highly enriched oxygen airflow, or both, and back again, based on one or more parameters.

Abstract: Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

Abstract: A method of forming an inorganic oxide coating on a monolith article is disclosed. The coated monolith article is suitable for the treatment of an exhaust gas. The method comprises spraying, as a dry particulate aerosol, inorganic particles comprising an aluminosilicate zeolite having a SAR of greater than 100:1 and a silicone resin to form a coating layer. The present invention also provides an uncalcined porous monolith article for use in forming a monolith article for the treatment of an exhaust gas. The uncalcined monolith article comprises a dry particulate composition comprising inorganic particles and a silicone resin.

Abstract: A method of determining a dry proppant concentration in a fracturing fluid includes combining a wet proppant with a carrier fluid in a mixer to form the fracturing fluid. The dry proppant concentration of the fracturing fluid leaving the mixer is determined using a moisture content of the wet proppant entering the mixer, wherein use of the moisture content prevents overestimation of the dry proppant concentration. The method can be preformed using a system for injecting fracturing fluid into a borehole, the fracturing fluid including a carrier fluid mixed with a wet proppant including a dry proppant dampened with a dampening liquid.

Abstract: The present disclosure provides a method comprising determining an ore map for a heap to identify a location of a recoverable metal value in the heap, delivering a leaching solution from a leaching solution source to a leaching solution regulating system, regulating at least one of a pressure, a mass flow rate, or a volumetric flow rate of the leaching solution to achieve a first target operational condition, wherein the first target operational condition is selected to optimize a set of operational parameters to maximize recovery of the recoverable metal value, delivering the leaching solution at the first target operational condition from the leaching solution regulating system to a subsurface leaching distribution system, and delivering the leaching solution at the first target operational condition from the subsurface leaching distribution system to the location of the recoverable metal value under a surface of the heap to leach and recover at least one metal value.

Abstract: A food cutter has a food travel axis, a blade carrier, and a plurality of disc blades mounted to the blade carrier. Each of the plurality of disc blades defines a corresponding blade rotation axis. Each disc blade is rotatable relative to the blade carrier about the corresponding blade rotation axis, which is perpendicular to and offset from the food travel axis. Each disc blade has a perimeter edge at a constant radius from the corresponding blade rotation axis. The perimeter edge of each disc blade has a series of alternating peaks and valleys, which have an amplitude in a direction parallel to the corresponding blade rotation axis. Other methods and apparatus are also disclosed.

Abstract: The present disclosure provides a method comprising determining an ore map for a heap to identify a location of a recoverable metal-bearing material in the heap, wherein the metal-bearing material comprises iron and at least one other metal value, delivering a leaching solution from a leaching solution source to a leaching solution regulating system, wherein the leaching solution comprises an effective amount of citric acid and hydrogen peroxide, regulating at least one of a pressure, a mass flow rate, or a volumetric flow rate of the leaching solution to achieve a target operational condition, wherein the target operational condition is selected to optimize a set of operational parameters to maximize recovery of the at least one other metal value, delivering the leaching solution at the target operational condition from the leaching solution regulating system to the subsurface leaching distribution system, and delivering the leaching solution at the target operational condition from the subsurface leaching d

Abstract: An insulating device can include an opening having a waterproof closure which allows access to a storage compartment within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

Abstract: A blade assembly includes a blade support frame, and a plurality of V-shaped blades removably fastened to the blade support frame. The blade support frame has a food flow path extending downstream, and a plurality of blade mounts distributed around the food flow path. Each V-shaped blade has a first end portion connected to one of the blade mounts, a second end portion connected to another of the blade mounts, and an intermediate portion extending from the first end portion to the second end portion into the food flow path. At the first and second end portions of each V-shaped blade, a respective one of the blade mounts overlies both the upstream edge and the downstream edge of the V-shaped blade to inhibit the V-shaped blade from rotating when impacted by food.
