Patent number: 5935138Abstract: A needle for endoscopic surgery is curved into an arc of more than 180.degree. and twisted, so that it forms a part of a spiral, with a lateral offset between the needle point and barrel. The needle is sized to fit through a 10 mm trocar and is also blackened, to improve its visibility in a bloody field. The needle curvature is preferably not constant over its entire length, so that different sections have different radii of curvature. The needle is particularly well adapted for performing laporascopically a procedure (Burch Colposuspension) that is used to treat female stress incontinence.Type: GrantFiled: September 24, 1997Date of Patent: August 10, 1999Assignee: Ethicon, Inc.Inventors: William C. McJames, II, Donald G. Miller, Thomas Nering, Robert Nering, Joseph Rollero, Lester E. Schaible

Patent number: 5758400Abstract: A plurality of lengths of window or door framing material which have weatherstrip receiving channels are disposed on a support surface (10). An operator controls (14) a carriage (16) to move from a home position to the opposite end of the support surface. The operator takes free ends of strips (18) of weatherstripping which extend through a pinch roller assembly (22). A portion of each strip near the free end is inserted into the channel manually and the free end is clamped (50, 52) in the carriage. When all the strips are started, the operator changes the differential pressure across the piston of a rodless cylinder (34) returning the carriage to its home position pulling the weatherstripping through the channels. At the home position, the carriage releases the free ends of the weatherstripping and the operator cuts the weatherstripping adjacent the pinch roller assembly. The framing material with inserted weatherstripping is removed from the support surface and the process repeated.Type: GrantFiled: June 21, 1996Date of Patent: June 2, 1998Assignee: Donald G. MillerInventors: Donald G. Miller, Jerry N. Snider

Patent number: 5683914Abstract: A method of pretreating aqueous chemical oxygen demand (COD) samples to remove the risk of potential chloride ion interference. The method comprises acidifying an aqueous COD test sample, and thereafter passing the acidified sample through a source of pentavalent bismuth (Bi.sup.5+) such as sodium bismuthate.Type: GrantFiled: September 25, 1995Date of Patent: November 4, 1997Assignee: Hach CompanyInventors: Donald G. Miller, Scott V. Brayton

Patent number: 5634098Abstract: An apparatus and method for testing software is disclosed. A test base is constructed on a storage device by creating a plurality of directories connected to form a hierarchical directory structure. Files associated with software programs to be tested are stored in directories within the hierarchical directory structure. Such files may include source code files, test input files and expected output files. Environment files and environment configuration files that specify values for environment variables are also stored in the test base. A test is run by invoking a test engine and passing to the test engine the name of an environment file and the name of a test. The test engine modifies the values of environment variables based on the specified environment file prior to executing the specified test. After modifying the environment based on the specified environment file and prior to executing the test, the test engine further modifies the environment based on any applicable environment configuration files.Type: GrantFiled: February 1, 1995Date of Patent: May 27, 1997Assignee: Sun Microsystems, Inc.Inventors: Micheal E. Janniro, Robert B. Jervis, Donald G. Miller, Jr.

Patent number: 5556787Abstract: A method of analyzing aqueous samples for Chemical Oxygen Demand (COD) which involves using an analysis reagent comprised of a mixture of stabilized Manganese III ion and an inorganic non-oxidizing acid such as sulfuric or phosphoric acid. Manganese III ion (or manganosulfuric acid complex) is purple, and, as it is reduced to Manganese II ion, the purple color decreases to colorless. Manganese III Chemical Oxygen Demand test is preferred over the presently available chromium reagent test because Chromium VI ion is a known carcinogen, the reagent is photosensitive and a silver catalyst is required. Manganese III is not carcinogenic or photosensitive and does not require a silver catalyst.Type: GrantFiled: June 7, 1995Date of Patent: September 17, 1996Assignee: Hach CompanyInventor: Donald G. Miller

Patent number: 4149677Abstract: A ring hammer for a reducing machine includes an annular body and tooth projected radially from the annular body and arranged in two rows, with the teeth of the one row being spaced axially from the teeth of the other row and further being offset circumferentially from the teeth of the other row. A reinforcing ring extends around the annular body in the space between the two rows of teeth and is formed integral with the annular body and the teeth of the two rows. The reinforcing ring tapers downwardly to the side faces of the annular body in the spaces between successive teeth of each row so that the teeth possess greater depth at their outside faces than at their inside faces. The reinforcing ring strengthens the ring hammer and renders the teeth less susceptible to breakage.Type: GrantFiled: November 14, 1977Date of Patent: April 17, 1979Assignee: American Pulverizer CompanyInventors: Donald F. Graveman, Donald G. Miller

Patent number: 4130157Abstract: A method of producing cast articles having internal cavities is disclosed. The method is particularly suitable for casting gas turbine components from nickel base and cobalt base superalloys. The method comprises: forming a core to the desired cavity configuration, the core consisting essentially of densified silicon nitride; securing the core within a mold; casting the alloy within the mold and around the core; removing the solidified cast article from the mold; and leaching the silicon nitride core from the casting in molten sodium hydroxide.Type: GrantFiled: July 19, 1976Date of Patent: December 19, 1978Assignee: Westinghouse Electric Corp.Inventors: Donald G. Miller, Frederick F. Lange

Patent number: 4015783Abstract: In a hammer mill or crusher for use in size reduction or even pulverizing rock, metals, or other materials, a rotating crusher and a contiguous surface are confined between opposing side walls and an inlet and discharge for the mill, with each side wall having supports designed for accommodating the arcuate formation of the crushing surface; a series of reversible grate bars span the distance between the side walls and associate at each end a structural shoe designed for stably positioning of each bar into the formed surface. Each grate bar and its end shoes are contoured on their sides to provide for their mating with adjacent bars and shoes when arranged into the crusher surface.Type: GrantFiled: July 10, 1975Date of Patent: April 5, 1977Assignee: American Pulverizer CompanyInventor: Donald G. Miller

Patent number: 4002302Abstract: The cage of a reducing machine is positioned within the machine housing below the rotor. One end of the cage is pivoted with respect to the machine housing, while the other end is suspended from chains which pass over sprockets so that when the sprockets are rotated the cage is either elevated or permitted to descend. Should the cage fail to descend under its own weight, a downwardly directed force is applied to it by pintle-type gears which mesh with gear segments on the cage. The rotation of the gears and the movement of the chains are synchronized.Type: GrantFiled: January 21, 1976Date of Patent: January 11, 1977Assignee: American Pulverizer CompanyInventor: Donald G. Miller

Patent number: 3957889Abstract: This invention relates to an improvement in a process for nitrating an aromatic or substituted aromatic compound e.g., toluene or ortho-xylene, by reacting such aromatic or substituted aromatic in the presence of nitric acid. The improvement for enhancing the rate of nitration as well as the selectivity of nitration at the para-position in this process comprises carrying out the nitration reaction in the presence of at least an effective amount of anhydrous calcium sulfate or soluble anhydrite.Type: GrantFiled: May 2, 1975Date of Patent: May 18, 1976Assignee: Air Products and Chemicals, Inc.Inventors: Barton Milligan, Donald G.
