Abstract: An upright induction chamber (100) is positioned within a melting tank (24) of a snow melting apparatus (20). The melting tank is filled with melting water. Shredded snow from a hopper assembly (22) is introduced into the upper end of the induction chamber along with heated melting water, to be mixed by an impeller fan pump (110) that is operated to force the melting water at sufficient speed through the induction chamber to overcome the buoyancy of the snow, thereby facilitating uniform distribution of the snow across the induction chamber and good mixing of the snow with the melting water. A portion of the liquid composed of the melted snow and melting water from the induction chamber is expelled from the melting tank, and a portion of the liquid from the induction chamber passes through a heat exchanger (34) positioned within the heating tank to be heated thereby and then re-introduced into the upper portion of the induction chamber.

Abstract: Downhole magnetic measurement devices and methods are provided for estimation of magnetic fields during drilling. In certain embodiments, a triaxial vector magnetometer 150 is provided and affixed to a drill string subassembly 125. While the drill string subassembly 125 is rotating, as during drilling operations, an average total magnetic field value (BTwR) is determined as an average of the instantaneous vector magnitudes of the three measured orthogonal component magnetic fields. In this way, near-bit 127 estimates of the downhole magnetic field may be obtained and used for a variety of functions. These downhole magnetic measurement devices may be useful determining magnetic fields, and estimating borehole inclination and azimuth of drill string subassemblies 125, 100 during drilling operations. Additionally, downhole magnetic measurement devices may be used for detecting the presence and distance to external ferromagnetic materials. In this way, these devices may be used for various applications, including, well avoidance, well intercept, and verification of instrument integrity.

Abstract: An oral orthosis includes a holder in the shape of a mouthpiece, including a curved arcuate trough-like upper section which receives a formable material. The formable material does not occupy the entire trough but rather includes voids between the formable material and the inner surfaces of trough of the holder to allow expansion of the formable material into the voids during the molding process when tooth pressure is placed on the formable material. This design results in elimination of the excess formable material which otherwise would require removal by trimming. Additionally, the formable material is placed in the trough in a configuration which includes indexing indentations along the centerline of the material, such that, during the molding process, the mouthpiece containing the formable material is easily centered along the edges of the user's teeth to provide a precise fitting.

Title: Method and apparatus for upgrading heavy oil
Inventor: LOURENCO JOSE
IPC: C10G63/04
Filed: 2013-01-07
Granted: 2019-11-26
Abstract: A method and apparatus for upgrading heavy oil is described, having a symbiotic relationship between a cracking reactor vessel and a steam reformer vessel. A first portion of an uncracked residue oil stream from the cracking reactor vessel is passed through a heat exchanger positioned within the steam reformer vessel and back to the cracking reactor vessel, such that a heat exchange takes place which heats the uncracked residue oil stream to promote cracking. A second portion of the uncracked residue oil stream from the cracking reactor vessel is injected directly into the steam reformer vessel. That portion of the uncracked residue oil stream not vaporized in the steam reformer vessel is converted into coke which becomes deposited in a fluidized bed of the steam reformer vessel. The fluidized bed activates steam which reacts with the coke to generate hydrogen. Hydrogen from the steam reformer vessel is directed into the cracking reactor vessel to assist with cracking.
