Abstract: A downhole tool has a main body that is cylindrical and includes a top coupling that couples to a drill string. A second body that is cylindrical is positioned at least partially within the main body. The second body has a bottom coupling that couples to a drill bit. Springs are positioned within the downhole tool and transmit an axial force to the drill bit. A first set of grooves is formed on an interior of the main body, and a second set of grooves is formed on an exterior of the second body. Balls travel within the first and second sets of grooves. At least some of the balls simultaneously engage the main body and the second body.

Abstract: A device for use downhole in a drill string includes a body that is cylindrical. The body has a longitudinal axis and top and bottom threads that can couple the body to other elements of the drill string. A radial shock absorber is coupled to an exterior of the body. The radial shock absorber has a piston with a piston axis. A portion of the piston extends to an exterior of the body. The piston can move along the piston axis between a retracted position and an extended position. In addition, a spring is located between the body and the piston. The spring can bias the piston, along the piston axis, radially outward relative to the longitudinal axis of the body.

Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

Abstract: A structure thermodynamic model, which models the physical characteristics of a controlled space, inputs a constraint state curve which gives constraints, such as temperature, that a controlled space is to meet; and outputs a state injection time series which is the amount of state needed for the controlled space to optimize the constraint state curve. The state injection time series curve is then used as input into an equipment model, which models equipment behavior in the controlled space. The equipment model outputs equipment control actions per control time (a control sequence) which can be used to control the equipment in the controlled space. Some embodiments train the models using training data.

Abstract: A process for the isolation and purification of substantially pure chemicals, including silica gel, sodium silicate, aluminum silicate, iron oxide, and rare earth elements (or rare earth metals, REEs), from massive industrial waste coal ash including a plurality of caustic extractions of coal ash at an elevated temperature, followed by an acidic treatment to dissolve aluminum silicate and REEs. Dissolved aluminum silicate is precipitated out by pH adjustment as a solid product while REEs remain in the solution. REEs are captured and enriched using an ion exchange column. Alternatively, the solution containing aluminum silicate and REEs is heated to produce silica gel, which is separated from the enriched REEs solution. REEs are then isolated and purified from the enriched solution to afford substantially pure individual REE by a ligand-assisted chromatography.

The bands may either be stationary with respect to the columns, or may move through the columns.

Abstract: A system and method for converting indications of interest to trade a private security into a firm order or intent to trade the security in a trading marketplace. The indications of interest can be converted into the firm order upon receipt of authorization information. The indication od interest is non-binding upon the parties until the trade is completed, and whereupon an economic fee is due. If the firm order is created and placed in the trading marketplace, then once a counterparty to the trade has been identified, the parties are obligated to close the trade. If the trade is not completed, then one of the parties pays the economic fee that is typically associated with the trade.

Abstract: A process disclosed herein is related to the isolation and purification of substantially pure chemicals, including silica gel, sodium silicate, aluminum silicate, iron oxide, and rare earth elements (or rare earth metals, REEs), from massive industrial waste coal ash. In one embodiment, the process includes a plurality of caustic extractions of coal ash at an elevated temperature, followed by an acidic treatment to dissolve aluminum silicate and REEs. The dissolved aluminum silicate is precipitated out by pH adjustment as a solid product while REEs remain in the solution. REEs are captured and enriched using an ion exchange column. Alternatively, the solution containing aluminum silicate and REEs is heated to produce silica gel, which is easily separated from the enriched REEs solution. REEs are then isolated and purified from the enriched solution to afford substantially pure individual REE by a ligand-assisted chromatography.
