摘要:
A tool for use in wellbore drilling that is suitable for use with a drill string for drilling a wellbore having an inner wall. The tool comprises a cylindrical abrasion surface for contacting the inner-wall and generating particles of solid material, and a smearing device coupled with the drill string for applying radial and circumferential force to smear the generated particles onto the inner wall of the wellbore.

Embodiments of the present invention provide compositions and methods for lining a wellbore. In certain aspects, the compositions and methods comprise providing a fluid composition that is solidifiable or gellable on exposure to actinic radiation of a predetermined wavelength at the wall of open-hole wellbore and providing actinic radiation at the predetermined wavelength to solidify or gel the composition. The predetermined wavelength lies in a range from 100 nm to 1500 nm.

Embodiments are directed towards employing hidden secrets on a client device to detect and deter piracy of a computer application. The computer application is partitioned into components, where a subset of the components is initially provided to the client device. In one embodiment, the computer application is unable to execute properly within the removed or other set of components. The removed components not provided to the client device may then be modified based on hidden secrets information and a verification component and provided over a network to the client device. If the verification component is unable to locate an armed secret, or detects that an armed secret is modified, the computer application may be inhibited from installation and/or execution. In one embodiment, a secret might be unarmed, such that its presence, absence, and/or modification might be ignored.

A composition and method for creosote control in firebox flues burning solid fuels combines hydrophobic metal additives with a fire accelerant. According to certain embodiments, the compositions may inhibit corrosion of metal flues in addition to creosote deposits. When the metal salts are added to an accelerant at effective concentrations, the combination delivers the metal catalyst to the lining of the exhaust system upon combustion. As such, the metals are conveniently and efficiently transported up the flue.

A system and method for determining and providing one or more guest passes for temporary access to one or more video games to a first player that was previously granted membership to a platform that offers access to playing these video games. One or more different determinations are made on information related to the first player and/or available video games to generate one or more guest passes for a video game that is at least somewhat relevant to the first player. In at least one embodiment, one or more of the different determinations can be intrinsically and/or extrinsically weighted to further refine the generation of a guest pass for a video games that is at least somewhat relevant to the first player, and thereby more likely to be offered by the first player to a second player. Also, the platform enables the determining and generating of the one or more guest passes to the one or more video games for the first player.
摘要:
A trailer (T) and a dock (D) are provided with substantially identical slat conveyors (10, 12). Each conveyor (10, 12) has alternating conveyor slats (36, 36′) and lifting/holding slats (38, 38′). The trailer (T) is backed up to the dock (D). Upper portions of the lifting/holding slats (38, 38′) are coupled together at their ends. The confronting ends of the conveying slats (36, 36′) are also coupled together. A mechanism carried by the dock (D) raises and lowers the upper portions of the two sets of lifting/holding slats (38, 38′) a drive mechanism carried by the dock (D) where it reciprocates both sets of conveying slats (36, 36′).
摘要:
A current transformer test method implemented using a test device, is useful to verify proper CT installation and operation, and does not rely on the generator (or other system) to be in a state of relatively high assembly. The test device allows a current transformer to be tested by supplying an alternating current (AC) signal to a primary winding of the current transformer to thereby induce an AC signal in a secondary winding of the current transformer. The test device is used to simultaneously monitor the phases of the supplied AC signal and the induced AC signal so that a determination can be made as to whether the current transformer secondary winding is properly installed relative to the current transformer primary winding, and to simultaneously monitor the current magnitudes of the supplied AC signal and the induced AC signal so that the turns ratio of the current transformer can be determined.
