  • Publication number: 20200269276
    Abstract: The disclosure relates to a method of conducting a coiled tubing operation. In one implementation, a method includes forming a tubing string, the tubing string having an outer surface. The method also includes applying a coating to an application portion of the outer surface of the tubing string. The application portion includes a portion of the tubing string that will be disposed in a horizontal section of a wellbore, and the coating has a surface energy lower than a surface energy of the outer surface of the tubing string to thereby reduce friction between the tubing string and a casing disposed in the horizontal section of the wellbore as the tubing string is lowered into the wellbore.

  • Patent number: 9957341
    Abstract: Biodegradable graft copolymers derived from a carbohydrate, including nitrogen-containing carbohydrates and modified carbohydrates, and at least one ?,?-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available stirred and/or continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying.

  • Publication number: 20140137570
    Abstract: A variable-thermal-resistance mounting system may include a cylinder coupled to a heat source, or heat load and a rod movably engaged to the cylinder and coupled to a remaining one of the heat source and heat load. The rod may be coupled to a heat load. The rod may be axially slidable relative to the cylinder between a collapsed position and an extended position in a manner causing a change in heat flow between the heat source and the heat load such that the warm-side temperature of the heat load is initially set at a substantially optimal value.

  • Patent number: 8026438
    Abstract: A front transparent conductor assembly and, in one embodiment, a photovoltaic cell, includes at least three transparent conductor layers. In one embodiment, first and second transparent conductors comprised of SnO2 are positioned above and below a third transparent conductor comprised of ZnO2. In one embodiment, the second transparent conductor layer is significantly thicker than either the first or third transparent conductor layers. In one embodiment of a photovoltaic cell incorporating such an assembly, a sealing layer of SiO2 is interposed between a superstrate and the first transparent conductor. In another embodiment, first and second intermediate layers of ZnSnO3 are incorporated into the assembly, with the first intermediate layer interposed between the first and second transparent conductors and with the second intermediate layer interposed between the second and third transparent conductors.

  • Patent number: 7935404
    Abstract: A method for selectively marking a surface of an optical disk includes providing an optical disk, wherein the optical disk includes a metal, an electrolyte disposed on the metal, and a photoconductor disposed on the electrolyte, applying a voltage to the optical disk, the voltage being associated with a desired anodization color, and selectively applying a laser to the photoconductor to initiate anodization of the metal.

  • Publication number: 20100151680
    Abstract: A substrate carrier is used in an in-line fabrication such as Plasma Enhanced Chemical Vapor Deposition (PECVD) for application of thin film on substrates. The carrier is in thermal communication with the substrate and thereby provides heat sinking. The carrier further permits movement of the substrate past a deposition apparatus at a deposition station.

  • Patent number: 7638252
    Abstract: A method of forming electrical devices can include electrophotographically printing a particulate material on a device substrate, and the particulate material can form at least a portion of the electrical device. An optional intermediate transfer member can also be used to improve reliability and performance of the process. Dry or liquid electrophotographic methods can be effectively used to form electronic devices on a wide variety of substrates not conventionally available in device fabrication.

  • Publication number: 20090139567
    Abstract: A multilayer conformal coating is optimized in both composition and geometry to protect the back and sides of a transparent-fronted thin-film solar photovoltaic panel or similar device from various damage mechanisms associated with long-term outdoor exposure without an additional backcap or edge frame. A “barrier stack” or “barrier layer” of inorganic moisture-barrier and chemical-barrier layers is applied to the back of the photovoltaic functional film stack, extending into a bare-substrate border zone around the functional stack edges. The barrier stack shields the functional stack from moisture and chemical invasion, and the coated border zone effectively seals the vulnerable edges of the functional stack. An “envelope stack” or “envelope layer” of thicker polymer films is applied over the mechanically delicate inorganic barrier stack and around the solar photovoltaic panel edges.

  • Publication number: 20080139003
    Abstract: A method to produce barrier coatings (such as nitrides, oxides, carbides) for large area thin film devices such as solar panels or the like using a high frequency plasma enhanced chemical vapor deposition (PECVD) process is presented. The proposed process provides a uniform deposition of barrier coating(s) such as silicon nitride, silicon oxide, silicon carbide (SiNx, SiO2, SiC) at a high deposition rate on thin film devices such as silicon based thin film devices at low temperature. The proposed process deposits uniform barrier coatings (nitrides, oxides, carbides) on large area substrates (about 1 m×0.5 m and larger) at a high frequency (27-81 MHz). Stable plasma maintained over a large area substrate at high frequencies allows high ionization density resulting in high reaction rates at lower temperature.
