Abstract:
A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.
Abstract:
An apparatus comprises a chemical precursor material formed into a pellet-shaped structure. The chemical precursor pellet may be used in a chemical vapor deposition process or in an atomic layer deposition process. A method of making the chemical precursor pellets comprises introducing the chemical precursor material into a pellet-shaped mold, compressing the chemical precursor material within the mold into a chemical precursor pellet, and removing the chemical precursor pellet from the mold. Another method for making the chemical precursor pellets comprises introducing a chemical precursor material into a pellet-shaped mold, liquefying at least a portion of the chemical precursor material within the mold, solidifying the liquefied chemical precursor material within the mold to form a chemical precursor pellet, and removing the chemical precursor pellet from the mold.
Abstract:
The present invention relates to a method and apparatus for containing and restraining the fragmentation of the jaw portion of a set of mechanical pipe tongs, under stress load conditions. The apparatus comprising a flexible belts or the like surrounding the jaws of the tongs like a girdle and attached to an energy absorber located at either side of the tongs' body.
