Patent number: 6846848Abstract: A hydrocarbon wax product from a hydrocarbon synthesis slurry comprising liquid synthesis product and catalyst particles is purified by introducing a portion of hydrocarbon synthesis slurry from a hydrocarbon synthesis zone to a treatment zone in which a treatment gas contacts the hydrocarbon synthesis slurry. Hydrogen or a hydrogen-containing gas is useful as the treatment gas. The gas treatment removes impurities from the hydrocarbon wax portion of the hydrocarbon synthesis slurry. Purified wax product is separated and removed in situ via wax withdrawal means. This avoids or minimizes the need for further treating the wax product.Type: GrantFiled: August 23, 2002Date of Patent: January 25, 2005Assignee: ExxonMobil Research and Engineering CompanyInventors: Robert Jay Wittenbrink, Loren Leon Ansell, Daniel Francis Ryan, Louis Francis Burns

Patent number: 6846234Abstract: A stuffing tube for a meat encasing machine that has a hollow stuffing tube. The hollow stuffing tube also has an inner chamber that is fluidly linked to the exterior of the hollow tube by a series of openings located in the wall of the stuffing tube. The openings and chamber allow water connected to a water source to be pumped into the stuffing tube. This causes a lubricating water surface to accumulate on the exterior of the stuffing tube providing lubrication for a sausage casing. This lubrication facilitates the sliding movement of the casing longitudinally along the stuffing tube.Type: GrantFiled: September 9, 2003Date of Patent: January 25, 2005Assignee: Townsend Engineering CompanyInventors: Steven P.

Patent number: 6845953Abstract: A train control system includes a control module that determines a position of a train using a positioning system and consults a database to determine when the train is approaching a portion of track monitored by a track circuit. When the train is near a track circuit, but while the train is still far enough away from the track circuit such that the train can be stopped before reaching the portion of track monitored by the track circuit, the train transmits an interrogation message to a transceiver associated with the track circuit. When the track circuit receives the interrogation message, a test is initiated. The test results are transmitted back to the train. The train takes corrective action if the track circuit fails to respond or indicates a problem.Type: GrantFiled: October 10, 2002Date of Patent: January 25, 2005Assignee: Quantum Engineering, Inc.Inventors: Mark Edward Kane, James Francis Shockley, Harrison Thomas Hickenlooper
