The present invention generally relates to methods and hydrate inhibitor compositions for inhibiting the formation of hydrates in a fluid comprising gas and water. More specifically, the method comprises contacting a hydrate inhibitor composition to a fluid. The hydrate inhibitor composition comprises a nonpolar solvent; a polar solvent; and a polymer, an oligomer, a dendrimer, or an acid or salt thereof.

Disclosed is a water manifold that provides a sturdy platform for both distributing water to various other locations or nodes and providing a support platform for a yard hydrant. The manifold is constructed of plastic and will not corrode. Further, the manifold is sturdy and provides a sufficiently large surface area to prevent sinking or tilting of the yard hydrant.

A coating system and method including a web path moving a substrate past a contacting element including a distribution manifold having a cavity, and a multiplicity of needle tubes in fluid communication with the cavity, the needle tubes each having a needle tip dispensing a coating material towards a point of contact between the substrate and the contacting element. In some embodiments, the distribution manifold separates into a manifold containing the internal cavity, and a removable cartridge having the plurality of needle tubes. The coating system and method can be used to apply a pre-metered coating material to the substrate.

Pipeline segments can contain cables, such as communication cables (e.g., fiber optic cables) within insulation material surrounding the pipeline segments. Cables can be embedded within the insulation material, run through conduits embedded within the insulation material, placed in channels formed in the insulation material, or otherwise. Channels containing one or more cables can be filled with supplemental insulation material, thus securing the cables within the channels. Pipelines created as disclosed herein can enable data transfer between distant points without the need to lay fiber optic cable in addition to the pipeline. Further, fiber optic cable embedded thusly can be used to sense conditions in the pipeline, such as leaks, seismic activity, strain, and temperature information.

A first flow path through which liquid flows in an intersection direction intersecting a vertical direction and a second flow path which is connected to the first flow path and through which liquid flows downward in the vertical direction are provided. The first flow path includes an intersection portion which has a surface intersecting the intersection direction and which allows a cross-sectional area of the first flow path to be gradually reduced in a plane perpendicular to the intersection direction as the first flow path extends to the second flow path.

A method is provided for non-intrusively determining cross-sectional variation of a fluidic channel. The method includes creating a pressure pulse in a fluidic channel using a hammer to strike an external surface of a fluidic channel. The method also includes sensing, by one or more sensors, reflections of the pressure pulse; and obtaining, from the one or more sensors, a measured pressure profile based on the sensed reflections of the pressure pulse. A forward model of cross-sectional variation of the fluidic channel is generated based on a baseline simulation. Using the forward model, a simulated pressure profile is generated. Using the measured pressure profile and the simulated pressure profile, an error is determined. When the error is outside a predetermined threshold, the forward model is updated based on the error. An estimate of cross-sectional variation of the fluidic channel based on the forward model is displayed.
