Patent number: 8937168Abstract: The invention provides methods of purifying rebaudioside A from a mixture comprising glycosides of the plant Stevia rebaudiana. The methods of the invention are useful for preparing highly pure rebaudioside A compositions from crude Stevia starting compositions that are typically considerably lower in rebaudioside A concentration. The highly pure rebaudioside A compositions are useful as non-caloric sweeteners in edible or chewable compositions such as food, beverages, medicine, candy, chewing gum, and the like.Type: GrantFiled: January 18, 2008Date of Patent: January 20, 2015Assignee: Cargill, IncorporatedInventors: Jeffrey C.

Patent number: 8286940Abstract: The present invention is directed to an injection molding valve configured to prevent the leaking or stringing of injected thermoplastic from the valve. The valve includes a housing having a first bore along a length thereof and a second bore intersecting the first bore. A rotatable member is inserted through the second bore and is in communication with a lever for the actuation thereof. The rotatable member includes a hole therethrough such that when the hole is aligned with the first bore, thermoplastic may travel freely through the first bore. The second bore further includes at least one groove in communication with a port for receiving injected thermoplastic. The injected thermoplastic is hardened to form an seal therein and configured to prevent thermoplastic from leaking out of the valve housing.Type: GrantFiled: September 5, 2008Date of Patent: October 16, 2012Assignee: MGS Mfg. Group, Inc.Inventors: John J. Hahn, Larry A. Schmitt

Patent number: 7686604Abstract: A screw for injection molding provides a coaxial piston that allows the effective cross-sectional area of the screw to be varied during the injection cycle permitting small shot metering with relatively large diameter injection molding screws. The screw is positioned within the injector barrel of a injection molding assembly and includes a number of threads disposed around its outer surface configured to advance molten plastic to the front of the barrel. The screw further includes a central bore having a piston slidably received within the central bore. The plastic shot to be forced out through the nozzle of the injection molding assembly is controlled by movement of the piston within the screw.Type: GrantFiled: December 20, 2004Date of Patent: March 30, 2010Assignee: MGS Mfg.

Patent number: 6824726Abstract: A method of sandwich molding, in which a first thermoplastic material is injected into a mold cavity followed by the injection of a second thermoplastic material expanding within the first thermoplastic material, eliminates the need for heated runner systems communicating from the injection nozzle of the injection molding machine to the mold cavity by employing a cold runner having sufficiently slow solidification time to allow subsequent injections from two injection sources. The backflow into the inactive branch is prevented by maintaining the injection nozzle against the mold until molding is complete.Type: GrantFiled: June 24, 2002Date of Patent: November 30, 2004Assignee: MGS Mfg. Group Inc.Inventors: Theodore Lemke, John J. Hahn, Brian Hartlmeier, Loren Albrecht
