Patent number: 5945684Abstract: An apparatus controls a stereotactic radiosurgery dose applied to an object being treated by a linear accelerator mounted on a gantry. The linear accelerator is capable of generating a beam having a path and a beam centerline, directed toward the object, and the beam is capable of having a plurality of angular positions relative to the object. The apparatus includes a turntable that is rotatable about an axis of rotation and defines a plurality of openings passing therethrough. Each opening has a center and receives therein a beam collimator of a preselected size. The turntable is disposed so that each of the plurality of openings may be rotated to where the center of the opening is coincident with the beam centerline, thereby allowing the beam to pass therethrough. A drive rotates the turntable about the axis of rotation and a sensor determines the angular position of the beam relative to the object.Type: GrantFiled: September 5, 1997Date of Patent: August 31, 1999Assignee: Medical University of South Carolina Foundation of Research DevelopmentInventors: Chan F. Lam, Stephen J. Nelson

Patent number: 4424368Abstract: This invention pertains to novel processes for preparing phosphorus derivatives of aminothiomethylcarbamates using as intermediates corresponding phosphorus derivatives of aminothiocarbamic halides. The carbamates are useful as pesticides against insects, mites, and nematodes. Two processes for preparing the corresponding intermediates are described. One preparation generally reacts an appropriate N-chlorothiophosphoramide with N-methylcarbamoyl halide. The other preparation generally reacts an N-chlorothiomethylcarbamoyl halide with an appropriate phosphoramide. The intermediate will react with various alcohols to produce the desired carbamates in the process of the invention.Type: GrantFiled: June 18, 1982Date of Patent: January 3, 1984Assignee: The Upjohn CompanyInventor: Stephen J.

Patent number: 4336207Abstract: This invention pertains to novel phosphorus derivatives of aminothiocarbamic halides and processes for their preparation. The carbamic halides are readily prepared by two general procedures. In one procedure an appropriate N-(chlorothio)phosphorus amide reactant is readily prepared by reacting the corresponding phosphorus amide with sulfur dichloride which reactant will react with N-methylcarbamoyl halide so as to produce the corresponding object compounds of this invention. In a different procedure the same compounds that are the object of this invention are prepared by reacting an appropriate corresponding phosphorus amide with an N-chlorothiomethylcarbamoyl halide reactant which reactant is readily prepared by reacting N-methylcarbamoyl halide with sulfur chloride. The novel compounds of this invention are intermediates for the preparation of pesticides.Type: GrantFiled: June 23, 1980Date of Patent: June 22, 1982Assignee: The Upjohn CompanyInventor: Stephen J.
