Title: Component of bottom hole assembly having upwardly-directed fluid cleaning flow and methods of using same
Inventor: TIPPLES ROBERT PETER DOUGLAS
IPC: E21B10/60
Filed: 2015-04-01
Abstract: A stabilizer for use in drilling a borehole includes a generally cylindrical body, a flow bore, a plurality of outwardly-extending blades and a valley disposed between adjacent blades.  A ring segment that is spaced from the body extends across at least one valley to define a flow passage. The body includes a hole or passageway for conveying drilling mud from the body's flow bore to between the blades. A drill bit for use in drilling a borehole includes a bit body, a flow bore in the bit body, a plurality of outwardly-extending blades, with a valley disposed between adjacent blades. A  ring segment that is spaced from the body extends across at least one valley to define a flow passage through which cuttings-laden drilling mud is conveyed. The bit body includes a hole or passageway for conveying drilling mud from the flow bore. The passageway terminates in an exit directed toward the flow passage so as to provide fresh drilling mud with a trajectory such that the fluid passes through the flow passage.

Title: System and method for treating waste water by means of passive phosphorus capture
Inventor: BUELNA GERARDO
IPC: C02F1/28
Filed: 2013-10-25
Abstract: The invention relates to a system and a method for treating waste water using a passive phosphorus-capture filter lined with wood activated by the impregnation of a metal in the form of hydroxide, more specifically aluminum hydroxide or iron hydroxide. This system demonstrates phosphorus removal performances which are very closely linked to the release of iron and which support the observation that iron releases follow a cyclical trend. The method according to the invention also clearly demonstrates the cyclical nature of the reduction of phosphorus, directly linked to the same cycle of iron release at the outlet. When the medium is aerobic, it can precipitate the released iron in the form of hydroxide and thereby limit the release of iron into the outflow water and consequently its residual phosphorus. This model thus allows the service life of the system to be extended, while simultaneously taking advantage of the precipitation/solubilisation cycle of the iron observed in the medium under reducing conditions.

Abstract: Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor (10) positioned on and projecting through a conduit wall (32). The sensor (10) consists of a conductive block (16) containing a heater (14) and having a heated wetted test surface (22) that is flush with the inside of the conduit wall (32) and in contact with the flow through the conduit (11). Within the conductive block (16) are two temperature sensors (18, 20) which are at different distances from the heated wetted test surface (22) and the heater (14). The periphery of the apparatus (10) is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface (22). By comparing the temperature differential between the two temperature sensors (18, 20) to the differential when no scale (40) is present, the presence of and amount of scale (40) can be determined, based on reduced heat transfer through the heated wetted surface (22) caused by the accumulated scale (40). The change in the temperature differential is directly proportional to the scale thickness for a given type of scale (40). When the thickness of the scale (40) is determined by another means, the nature of the scale (40) can be implied. The sensitivity of the measurement can be adjusted to accommodate a very wide range of bulk liquid (36) or ambient temperature via adjustment of the heat flux through the provided secondary heat flux path.

Abstract: A safety barrier is formed of framing, including a guard rail that defines the infill below the rail without the use of pickets. The infill is covered with mesh screen, which may be made of nylon which has greater tensile strength than conventional fiberglass. The mesh screen is held to the framing by an extruded base. The base has a central channel between two flat spline grooves. Flat splines hold mesh screen in their respective grooves more securely than conventional friction-based channel splines. A metal plate is positioned in the central channel to enables screws that secure the base to be tightened to hold it to the framing better. The elimination of pickets in the infill leaves the view unobstructed and allows other treatments of that portion of a deck or porch that are more aesthetically pleasing without compromising safety.
