    Abstract: A drill string sub for a rotary steerable drilling system wherein a flow diverter is configured, which flow diverter is configured rotatable about a drill string longitudinal axis at a relative rotation frequency relative to the drill string sub, to preferentially direct drilling fluid into a selected azimuth segment which is stationary relative to the flow diverter. A downhole data unit is configured to provide an information signal representing downhole data. An encoder operatively connected to the flow diverter to modulate the relative rotation in accordance with the information signal for transmitting information representing the downhole data to be detected uphole.

    Abstract: Disclosed is a system and method for wirelessly monitoring process conditions within a reactor vessel. An array of sensor-enabled radio frequency identification (RFID) tags is placed at known heights within a catalyst bed of a vessel and are used to measure 10 various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three-dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.

    Abstract: A housing for a seismic sensor station has a base and a removable lid, which when assembled together form a shell whereby the base and the removable lid both have a shell side and an exterior side. A sensor spike, protruding outward from the shell, may be attached to the base on the exterior side of the base. The housing is further provided with two cable docking ports, each allowing passage of a fiber optical cable from outside to inside the shell. The two cable docking ports are exclusively provided in the removable lid.

    Abstract: Presented is a catalyst composition having exceptional properties for converting sulfur, sulfur compounds, and carbon monoxide contained in gas streams by catalyzed hydrolysis, hydrogenation and water-gas shift reactions. The catalyst comprises underbedded molybdenum and cobalt with an overlayer of molybdenum and cobalt. These metals are present in the catalyst within certain concentration ranges and relative weight ratios. The underbedded metals are present in the catalyst within a specified range relative to the overlayer and total metals. The underbedded metals are formed by co-mulling an inorganic oxide with the catalytically active metals of molybdenum and cobalt. The co-mulled mixture is calcined and then impregnated with overlaid molybdenum and cobalt.
