Patent number: 6607920Abstract: An instrument for microwave-assisted chemical processes is disclosed that provides greater flexibility in carrying out microwave-assisted chemistry under varying conditions. The instrument includes a source of microwave radiation, and a cavity in communication with the source, with the cavity including at least one wall formed of two engaged portions that form a barrier to the transmission of microwaves when so engaged. The engaged portions are disengagable from one another, and one of the portions includes a microwave-attenuating opening.Type: GrantFiled: January 31, 2001Date of Patent: August 19, 2003Assignee: Cem CorporationInventors: William Edward Jennings, Edward Earl King

Patent number: 6534140Abstract: A self sealing vessel assembly for high pressure microwave assisted chemistry is disclosed. The vessel assembly includes a polymeric cylinder and a circular polymeric cap for the cylinder, the cylinder being closed at one end and open at the other end to receive the cap. The open end of the cylinder has a lip that is beveled inwardly from the open end, and the circular polymeric cap has a beveled lower edge that engages the beveled lip when the cap is place upon the polymeric cylinder. For high pressure applications, a choke cylinder depends from the beveled lower edge of the cap, and has an outer diameter substantially the same as the inner diameter of the polymeric cylinder so that the choke provides a self sealing mechanism for the cylinder as pressure from a chemical reaction increases within the cylinder. A composite sleeve surrounds the polymeric cylinder, and includes at least one wound fabric layer in which the winding is selected from the group consisting of filaments and yarns.Type: GrantFiled: March 1, 1999Date of Patent: March 18, 2003Assignee: CEM Limited, L.L.C.Inventors: Wyatt Price Hargett, Jr., Edward Earl King

Patent number: 6521876Abstract: A volatiles analyzer is disclosed that includes a source of microwave radiation that can selectively produce at least one predetermined frequency of microwave radiation. A cavity is in communication with the source. The walls of the cavity form a twelve faced polyhedron in which eight faces form a regular octagon and having two faces that are both non-parallel and non-perpendicular to the eight faces of the regular octagon. The polyhedron focuses microwave energy of the predetermined frequency on a balance pan while supporting a plurality of TM and TE modes in the cavity.Type: GrantFiled: June 25, 2001Date of Patent: February 18, 2003Assignee: CEM CorporationInventors: William Edward Jennings, Matthew Donald Barrett, Edward Earl King

Patent number: 6268570Abstract: The invention is a method of measuring an apparent weight of a substance, while concurrently measuring a surface temperature of the substance and an ambient air temperature surrounding the substance, then predicting buoyancy forces acting upon the substance based on these temperature measurements. Thereafter, the true weight of the substance can be determined by correcting the apparent weight by the predicted buoyancy forces acting upon the substance.Type: GrantFiled: September 17, 1999Date of Patent: July 31, 2001Assignee: CEM CorporationInventors: Byron E. McLendon, Edward Earl King

Patent number: 6246038Abstract: A microwave vessel system for external and noninvasive pressure monitoring and control is disclosed. The system comprises a reaction vessel formed of a material that is transparent to microwave radiation, with the reaction vessel including a portion that is movable under pressure generated by a chemical reaction inside the vessel while maintaining the reaction sealed inside the vessel. A sensor is adjacent to the movable portion of the vessel for detecting the motion of the movable portion as the portion responds to pressure generated inside the vessel. The system includes means for maintaining the sensor against the movable portion while microwaves are applied to the vessel so that the movement of the movable portion under pressure is detected by the sensor.Type: GrantFiled: March 1, 2000Date of Patent: June 12, 2001Assignee: CEM Limited, LLCInventors: James Edward Thomas, Wyatt Price Hargett, Jr., Edward Earl King

Cost estimating system using parametric estimating and providing a split of labor and material costs
Patent number: 5793632Abstract: A parametric cost estimating model, which can be software-based, provides a capability for inputting specific labor rates and burdening or overhead information for a given installation. Other inputs are project-specific depending on whether a hardware or a software system is being estimated. The process and model provide estimating information as to costs to develop and produce specific hardware or software systems and also provide a split as to labor and material costs for such systems.Type: GrantFiled: March 26, 1996Date of Patent: August 11, 1998Assignee: Lockheed Martin CorporationInventors: Bruce Fad, Roy Summers, Anthony DeMarco, Todd Geiser, James Walter, Ben Chackman, Earl King
