Abstract: Coriolis direct wellhead measurement devices and methods are provided. The devices and methods allow for continuous monitoring, more frequent data, and greater accuracy in quantitative and qualitative measurements of well performance. In an embodiment: an entrained gas severity of a wellhead is determined based on a determined drive gain threshold, at least one variable is output based on the determined entrained gas severity, and a respective confidence indicator correlating to the at least one variable is output. One mode of operation includes continually averaging the at least one variable over a predetermined time interval and out-putting a respective single averaged data value. Another mode of operation includes outputting at least one instantaneous variable at predetermined and uniform time intervals. Diagnostic information and user alerts are also output to provide reliable decision making information to an operator.

Abstract: A method for determining fluid characteristics of a multicomponent fluid is provided. The method includes a step of measuring a first density, ?1, of a multicomponent fluid comprising one or more incompressible components and one or more compressible components at a first density state. The method further includes a step of adjusting the multicomponent fluid from the first density state to a second density state. A second density, ?2, of the multicomponent fluid is then measured at the second density state and one or more fluid characteristics of at least one of the compressible components or the incompressible components are determined.

Abstract: A buoyancy vehicle operable to navigate on a fluid from a sitting and reclined position. The vehicle provides facilitated access and operational control to propulsion and navigational systems that can be operated from a sitting or reclined position. Consequently, a user who cannot stand or perform rigorous physical activity may operate the buoyancy vehicle. The buoyancy vehicle comprises at least one buoyant member configured to float on the fluid with sufficient buoyancy to support the vehicle and the operator. A frame portion attaches to the buoyant member. The frame portion is generally tubular and sufficiently lightweight and/or hollow, so as to enhance the buoyancy of the vehicle. A center board retractably extends from a bottom surface of the frame portion. A seat is configured to support an operator and/or a load, and enable easy access to the navigational and propulsion systems for operating the vehicle.

Abstract: Systems and methods for bearing housings are disclosed. A labyrinth seal bearing housing includes: a first seal element that is structured and arranged to be connected to a wall of a mixing vessel; a second seal element that is structured and arranged to be connected to a rotatable shaft; and a bearing support that is structured and arranged to be connected to the first seal element. The second seal element is configured to rotate relative to the first seal element and the bearing support. The first seal element and the second seal element are structured and arranged to create a tortuous flow path between an exterior and an interior of the mixing vessel.

Abstract: An activated carbon material for removing a contaminant from a liquid. The activated carbon material can be a plurality carbon grains that have a pore volume of approximately 0.1 milliliters per gram (mL/g) in the range of less than about 15 angstroms in width. The carbon grains can also have or contain a nitrogen-containing species having a concentration of more than 2 atomic percent nitrogen.

Abstract: Embodiments of the invention relate to the automatic ordering of replacement parts in product servicing. One aspect of the invention concerns a service system including multiple components, a service initiator for identifying a component in the system that has failed or does not operate according to a service threshold, and determining whether the identified component needs a replacement part based on the service threshold. The service system automatically orders a replacement part if the replacement part is needed and notifies a user of the part order. The service threshold may be dynamically adjusted.

Abstract: A stool includes a collapsible frame, a triangular seat and a back. The frame includes a bottom hub with three telescopingly adjustable legs and enlarged feet. A top hub is rotatably coupled to the bottom hub for 360 degree rotation, and includes three seat-supporting arms that extend from the top hub, and a pair of uprights that extend from two of the arms. The seat hook-attaches to loops on ends of the arms, and the back extends between the uprights. The legs and arms are pivoted to their respective hubs, but the pivots are slightly frictional so that the arms and legs remain in adjusted positions, with stops on the hubs stopping the legs and arms in their upwardly-pivoted use positions. The frictional pivots include lubricious plastic that facilitates quiet unfolding of the stool, which is important when hunting.
