Abstract: A wellhead apparatus comprising a first part that is mountable to a portion of a wellhead or proximal to the wellhead and a second part that is mountable to a component of wellhead operation equipment, wherein the component is operatively connectible to the wellhead, wherein the wellhead identifier generates an identifier signal when the first part is proximal the second part and is receivable by a user to identify the wellhead from a plurality of wellheads when the wellhead and the component are operatively connected. A wellhead identifier system comprising a detectable signal generator mountable to a component of wellhead operation equipment, a sensor configured to detect the detectable signal for generating object-based sensory information, and a controller circuit for receiving the object-based sensory information and for identifying a wellhead on a well pad where a wellhead operation has or will commence on the wellhead.

Abstract: An apparatus, a system and a process for regulating a wellhead control mechanism. The apparatus may control actuation of a wellhead control mechanism by moving a moveable body of the apparatus between a first position and a second position. When the apparatus is in the first position a valve actuator is actuatable. When the apparatus is in the second position the valve actuator is physically interfered from actuating. Additionally, when the apparatus is in the second position, the wellhead control mechanism cannot be actuated and is held in either an open, a partially open or a closed position. Further, a system may directly control actuation of a wellhead actuation mechanism.

Abstract: A seat assembly is provided with a seat bottom and a seat back extending upright from the seat bottom. At least two side bolster seating surfaces are spaced apart laterally on at least one of the seat bottom and the seat back. A bolster support assembly is provided adjacent each of the two side bolster seating surfaces. Each bolster support assembly has an air bladder and a rigid support mounted to the air bladder and positioned between the side bolster seating surface and the air bladder. When the air bladder is in an inflated position, a contact width of the rigid support along the bolster seating surface is greater than a bladder width.

Abstract: A stabilized microcapsule includes a liquid hydrophobic core including an essential oil and an aromatic monoaldehyde, and a shell encapsulating the core, the shell including a plurality of amino-functionalized inorganic nanoparticles. Also disclosed is a dispersion including a plurality of the stabilized microcapsules. The microcapsules and dispersions can be particularly useful for treating a bacterial biofilm.

Abstract: Various embodiments disclosed relate to protein films and methods of making the same. In various embodiments, the present invention provides a method of making a protein film including placing on a substrate a protein solution, to form a precursor protein film. The protein solution includes one or more proteins. The method includes compressing the precursor protein film to form a protein film.

Abstract: A method for analyzing a turbulent fluid flow field includes the steps of: creating a mathematical model of a physical object; simulating a flow field around said model, wherein said flow field is at least partially turbulent; generating time series flow data output data representative of said flow field; and identifying repeating turbulent flow patterns in said flow data. These features are identified by selecting at least one frequency range of interest; filtering the flow data based on the frequency range; and observing coherent structure in the filtered data. The method may be implemented as a software program running on a computer.
