Abstract: A process to treat fines tailings generated from mining operations, wherein tailings material is sprayed onto a solid substrate as a thin layer and allowed to dry. The spray may be re-applied on top of the dried tailings film leading to multiple layers of dried tailings solids. The method may yield a solid, dry, and consolidated tailings material.

Abstract: Aspects of the subject technology relate to systems and methods for pumping multiple wellbores to form and stabilize fractures during a fracturing job. A fluid pump of known operating pump capacity measurable in barrels per minute is selected. The pump is fluidly connected with each of a plurality of cased wellbores in a subterranean formation for providing fracturing fluid to each of the wellbores. The plurality of wellbores each have at least one perforation through a casing of the wellbore that has a known rate range within which fracturing fluid is required to successfully fracture the subterranean formation outside the perforation through the perforation. The pump is configured to provide fracturing fluid to each of the perforations within the known rate range of the respective perforation to successfully fracture the subterranean formation outside of the perforation.

Abstract: A downhole tool comprises a housing defining a flow path therethrough in an axial direction from an upper opening to a lower opening. A poppet valve is mounted within the housing. The poppet valve includes an upper member defining an upper chamber mounted in the flow path so that flow through the flow path flows around the upper member, and a valve seat mounted in the flow path with an opening therethrough. A valve poppet is mounted for longitudinal movement within the flow path between a closed position in which the valve poppet seats against the valve seat to block flow through the flow path and an open position in which the valve poppet is spaced apart from the valve seat to permit flow through the flow path. This can restrict/mitigate sand fall-back, e.g., with flow paths designed to prevent/mitigate sand fall-back and for protection of the poppet from sand/debris.

Abstract: Disclosed herein are system, method, and computer program product embodiments for a processor health monitoring and failover and failback system. An embodiment operates by detecting a failure event that indicates a reduced functionality of a primary processor, wherein the primary processor is configured to process incoming messages, and identifying a failure timestamp. An activation request, including the failure timestamp, is transmitted to a replica processor that is configured to process the incoming messages beginning with an incoming message corresponding to or later than the failure timestamp. A recovery event that indicates an increased functionality of the primary processor is detected, and a corresponding recovery timestamp is identified. A deactivation request, including the recovery timestamp, is transmitted to the replica server, wherein the primary processor is configured to process the incoming messages beginning with an incoming message corresponding to or later than the recovery timestamp.

Abstract: A dew point corrosion resistant heat exchanging system having a plurality of hollow heat transferring tubes through which cooler ambient air or hot combustion product gasses flow. The other of the air or gas flows across the outer surfaces of the tubes, and heat is transferred from the hot gasses to the ambient air, thus heating the air. A portion of the tubes includes an inner liner forming an air pocket chamber between the liner and the outer wall of the tube. The air pocket chamber provides heat transfer advantages that maintain the tubes at a temperature above the dew point of the gasses in the system, thus inhibiting corrosion of the tubes.

Abstract: Apparatus and methods are described, including apparatus for use with a subject who shares a bed with a second person. A motion sensor detects motion of the subject and motion of the second person, and generates a motion signal in response thereto. A control unit identifies components of the motion signal that were generated in response to motion of the subject, by distinguishing between components of the motion signal that were generated in response to motion of the subject, and components of the motion signal that were generated in response to motion of the second person. The control unit analyzes the components of the motion signal that were generated in response to motion of the subject and generates an output in response thereto. Other applications are also described.

Abstract: The present invention relates to an artificial foot including a foot body part, a toe part rotatably disposed at a first end of the foot body part, a toe joint connecting the foot body part and the toe part to each other, and an adapter disposed on a top of a second end of the foot body part. According to the artificial foot, since the toes of the artificial foot rotate when a wearer walks, when the artificial toes come in contact with the ground, energy is stored due to the load by the weight and the toes kick off the ground as much as the elastic energy accumulated by the spring, so the toe members of the artificial foot do not drag on the ground. Accordingly, the wearer does not need to lift up the hip joints, so the wearer can walk similar to normal walking.

Abstract: A cementing tool with a top seal and a bottom seal may be positionable within a casing string of a wellbore.

One or more operational parameters, such as cementing parameters, may be adjusted based, at least in part, on the sensing measurement signal.
