Patent number: 11607723Abstract: A method and apparatus for providing an estimate of uniformity of wall thickness of a centrifugally cast object, such as a pipe cast from molten iron, substantially immediately after the casting process is complete. The volume of molten metal entering the mold over time is determined and correlated with casting machine position and velocity data to estimate wall thickness along the length of the pipe. Process defects can then be identified promptly and corrective action taken.Type: GrantFiled: May 5, 2022Date of Patent: March 21, 2023Assignee: United States Pipe and Foundry Company, LLCInventors: Kenneth J Watts, Stephanie R Holtz

Patent number: 6890290Abstract: The present invention relates to a method and apparatus for folding and sealing a web of material to form an item with a contoured seal such as a valve bag. Folding apparatus form the web of film into a continuous tubular web having upper and lower sections, a closed side and an open side. The open side has two folded flaps that extend into an inside area of the tubular web. A longitudinal sealer includes a floating sealer located inside the tubular web. The floating sealer and its contoured heating element are selectively and intermittently pressed against the overlapping flaps to form a contoured seal that bonds the flaps together. The contoured seal defines a self-sealing valve port through which product is poured to fill the bag. Pairs of repelling magnets biasingly elevate the floating sealer above the overlapping flaps when the longitudinal sealer is in its release position.Type: GrantFiled: October 31, 2003Date of Patent: May 10, 2005Assignee: Amplas, Inc.Inventors: Donald J. Pansier, Kurt R. Holtz, John M. Hathaway, Greg S. Winicki

Publication number: 20050059127Abstract: A method for extracting proteins from the intercellular space of plants is provided. The method is applicable to the large scale isolation of many active proteins of interest synthesized by plant cells. The method may be used commercially to recover recombinantly produced proteins from plant hosts thereby making the large scale use of plants as sources for recombinant protein production feasible.Type: ApplicationFiled: October 29, 2004Publication date: March 17, 2005Inventors: Thomas Turpen, Stephen Garger, Michael McCulloch, Terri Cameron, Michelle Samonek-Potter, R.

Patent number: 5290374Abstract: A pin type retainer for roller bearings is stamped in one piece from flat metal stock. The flat metal is first drawn into a cup shape having a broad flange around an open first end and a closed second end. The closed end provides solid support and alignment while stamping pins from the broad flange. The pins are then final shaped by swaging or machining into cross sectional forms for a variety of applications. The second end is then opened to form a ring. The pin type retainer can be modified for use with a retaining ring or a seal against contaminants. The pin type retainer can be formed from a variety of materials, including steel. An embodiment using plastic resin is also disclosed.Type: GrantFiled: October 27, 1992Date of Patent: March 1, 1994Assignee: The Torrington CompanyInventors: James R. Holtz, Stephen M. Mondak

Patent number: 4927487Abstract: Apparatus and a process for bonding a core member to a housing member, particularly, in instances in which the members do not mate in a contiguous fashion. The invention includes some manual and some semi-automatic functions, but is largely automated and computer controlled. A conveyor carries an assembly of an initially joined but unbonded core member and housing member along a series of discrete stations. After some preparatory steps in the process, an initial continuous bead of sealant is first applied on one side of the assembly to close off the space between the members and thereby form a cavity between them. The bead is cured, then the assembly is inverted and the cavity is filled with an anaerobic bonding material. A second continuous bead of sealant is then applied on the other side of the assembly to close off the remaining space between the members as well to isolate the bonding material within the cavity.Type: GrantFiled: November 30, 1988Date of Patent: May 22, 1990Assignee: Loctite CorporationInventors: William A. Gelinas, Edwin R. Holtz, Dennis J. Argazzi, Robert L. Smigel, Dan W. Wiley
