Abstract: A device for autonomously folding a deformable article includes a rotatable platform configured to receive the deformable article and at least one movable elongation in operable communication with at least one elongation drive. The at least one movable elongation is configured to raise and lower from the surface of the rotatable platform, move parallel to the surface, and manipulate the deformable article to thereby fold the deformable article at one of the one or more fold lines. The device includes a table drive configured to rotate the rotatable platform about a central axis such that the at least one elongation aligns with one of the one or more fold lines, and at least one sensor configured to detect the deformable article position and orientation on the rotatable platform. A controller is in operable communication with the at least one elongation drive, the table drive, and the at least one sensor.

Abstract: Coacervate gels having excellent shear viscosities and other properties are made with anionic or cationic polymers, a smaller amount of a surfactant having a charge opposite that of the polymer, and a hydrophobic alcohol and an effective amount of a phosphorus-containing compound sufficient to increase the viscosity of coacervate gels up to 3 times as compared to the gels in the absence of the phosphorus-containing compound. The Zeta Potential of the gel is maintained at an absolute value of at least 20. Optional gel promoting additives include betaines and amine oxides. A preferred gel comprises poly diallyl dimethyl ammonium chloride, a lesser amount of sodium lauryl sulfonate, and lauryl alcohol. The gels are particularly useful in well drilling fluids and well fracturing fluids.

Abstract: Water soluble nonionic friction reducers and added to coacervate gels having excellent shear viscosities and other properties. A preferred gel comprises poly diallyl dimethyl ammonium chloride, a lesser amount of sodium lauryl sulfonate, and lauryl alcohol. Excellent friction reducing properties are manifested; a particularly practical use for the compositions is in subterranean formation fracturing.
