A homogeneous, aqueous mold release solution including: 5 to 90 wt % water; 3 to 40 wt % polyvinyl alcohol; 0.01 to 3.2 wt % surfactant; 1 to 20 wt % sugar alcohol; 0.005 to 1.05 wt % defoamer; and up to 50 ppm biocide, where a total of all components adds to 100 wt %. The mold release solutions have a viscosity in a range from 20 to 600 cps when measured at 23° C. In another aspect, embodiments disclosed herein relate to a homogeneous, aqueous mold release solution including: 5 to 85 wt % water; 10.5 to 15 wt % polyvinyl alcohol; 0.56 to 0.8 wt % surfactant; 1 to 8 wt % sugar alcohol; 0.01 to 0.3 wt % defoamer; and up to 50 ppm biocide, wherein a total of all components adds to 100 wt %. Also disclosed are films prepared from the mold release solutions, as well as methods of coating a substrate using such mold release solutions.

Mold release for engineered stone and other mold release applications

Various embodiments disclosed relate to a composite mandrel. In various embodiments, the present invention provides a method of forming a composite mandrel for use in a subterranean formation. The method can include securing an elongated mold to at least a portion of an exterior surface of a rigid tubular to form a cavity between the mold and the exterior surface of the rigid tubular. The elongated mold can include a recessed portion. The cavity can extend longitudinally along the tubular. The method can include filling the cavity with a curable resin composition. The method can also include curing the resin to provide a cured resin including a utility recess corresponding to the recessed portion. Curing the curable resin composition can form the composite mandrel including the tubular and the cured resin.

Composite Mandrel for use in subterranean formation

A water soluble film useful in unit-dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer; and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water-soluble film simultaneously satisfying requirements in regard to water solubility, biodegradability, and physical properties, even when used for packaging of harsh, oxidizing chemicals.

A metal seated floating ball valve for in-line repair has a valve body, a ball mounted in the valve body, a stem connected to the ball, and a bonnet connected to the valve body. The floating ball valve further has a first seat and a second seat adjacent the ball mounted in the valve body, an energizing ring mounted in the valve body proximate the first seat and in series with the first seat and the second seat, and a valve seat bias mounted in the valve body proximate the energizing ring and in series with the energizing ring. The energizing ring may have a slot near the upper end and a wedge surface along the lower end.

In-line repairable metal seated floating ball valve

A tubular fluid flow device of varying outside dimensions adapted for use in a high pressure, rapidly cycling temperature environment, an isolation ball valve, a ball valve isolation method and a catalyst transfer method. The flow devicecan have a tubular memberhaving at least one locusof non-uniform outside dimension and an axial flow passagewith a uniform inside diameter between opposite end connection elements. A thermal sleeve linercan be disposed about the axial flow passage in a boreformed in the tubular member, wherein the sleeve comprises an outer surface having a thermal barrier coating. A pressure-relief passageis provided in fluid communication between the axial flow passage and an interface between an exterior surface of the thermal sleeve liner and an inner surface of the bore.
