Abstract: A material working attachment for a vehicle includes: (a) a working implement for engaging and working material on a ground surface during operation of the vehicle in a working direction along the ground surface; and (b) a coupling mechanism for attaching the working implement to the vehicle. The coupling mechanism includes: (i) a first coupling portion attached to the working implement and having at least one coupling channel extending along a coupling axis, the coupling axis alignable parallel with the working direction, and (ii) a second coupling portion attachable to the vehicle, the second coupling portion having at least one arm alignable parallel with the coupling axis for sliding of the at least one arm in a respective coupling channel to releasably interconnect the first and second coupling portions for attachment of the material working implement to the vehicle.

Abstract: A process for recovering lithium phosphate and lithium sulfate from a lithium-bearing solution, such as a brine or pregnant process liquor is described. The process includes adding phosphate to the lithium-bearing solution to precipitate lithium phosphate and then separating the resulting lithium phosphate precipitate from the solution. The separated lithium phosphate precipitate is then digested in sulphuric acid to produce a digestion mixture from which a lithium sulfate precipitate is separated. An alkali metal hydroxide is added to the separated solution to produce an alkali metal phosphate solution and this is recycled for use as phosphate in the first step of the process.

Abstract: Aspects of the current subject matter are directed to a sensor assembly of an analyte monitoring device including one or more microneedle arrays. Aspects are directed to components and architecture of a sensor assembly to implement power and processing aspects of a microneedle array-based continuous analyte monitoring device for the detection and measuring of an analyte. A source of a power-on event is determined, and the analyte monitoring device is transitioned to a mode that corresponds to the determined source. When a power-on event is determined to be a valid power-on event, the analyte monitoring device is transition to a mode that corresponds to a type of the valid power-on event.

Abstract: The disclosure relates to processes for extracting lithium from an uncalcined lithium-bearing silicate and recovering a lithium salt therefrom. A slurry of the uncalcined lithium-bearing silicate and a caustic solution is heated in an autoclave to provide a Li-rich sodalite phase. The Li-rich sodalite phase is leached with a dilute acid to produce a lithium-rich pregnant liquor. Various subsequent processes to treat the lithium-rich pregnant liquor to recover a lithium salt, such as lithium phosphate, lithium carbonate, lithium sulphate or lithium hydroxide, are described.

Abstract: A reconfigurable material moving attachment for a vehicle includes a blade having a blade working face directed toward a front of the blade; and a coupling mechanism for reversibly mounting the blade to the vehicle. The coupling mechanism includes a first coupling portion fixed to the blade and a second coupling portion attachable to the vehicle. The second coupling portion is releasably interconnectable with the first coupling portion in: (i) a forward pushing configuration, in which the blade working face is directed away from the vehicle for pushing of the blade during forward operation of the vehicle to collect and push material in a material collection space adjacent the blade working face, and (ii) a back-dragging configuration, in which the blade working face is directed toward the vehicle for pulling of the blade during reverse operation of the vehicle to collect and back drag material in the material collection space.

Abstract: Described herein are aqueous based foams for use in drilling operations. The foams can be used in below bubble point drilling operations to control the migration of reservoir gases (e.g., hydrogen sulfide) to the surface.

Abstract: A packaging arrangement for 30 mm×173 mm ammunition rounds. The packaging arrangement has a heavy duty standoff device of defined height, which standoff device mounts a very high strength support plate and a heavy duty restraining plate. The support plate has through holes (of diameter slightly less than the rounds defined maximum diameter) to hold the rounds of in an upside down position and from sliding/moving. The height of the standoff device keeps the rounds from being able to touch the bottom of the metal box. The restraining plate has multiple recessed areas sized to accommodate the back ends of the said rounds. The packaging arrangement is lowered into a metal box with handles for carriage purposes. On top, there are Homosite filler pads, and the box accommodates a top lid.

Abstract: A process for recovering lithium phosphate and lithium sulfate from a lithium-bearing silicate is described. The process includes adding from 800 kg/t to 1600 kg/t of sulfuric acid to a slurry of the lithium-bearing silicate and from 40 kg/t to 600 kg/t of a source of fluoride to produce a leach mixture and heating said leach mixture. A lithium-bearing solution is then separated from the leach mixture and its pH is increased sequentially to pH 3.5 to 4, pH 5.5 to 6 then pH 10.5 to 11 to precipitate, respectively, a first, second and third set of impurities therefrom. The first, second and third sets of impurities are separated from the lithium-bearing solution and lime is added to maintain a soluble Ca concentration of at least 30 mg/L. The lithium-bearing solution is then softened by adding a two sequential amounts of phosphate to precipitate fluorapatite and apatite, respectively. A third amount of phosphate is added to produce a lithium phosphate precipitate which is then separated.
