Patent number: 11885442Abstract: The present invention relates to mechanical joining of Nickel Titanium tubes, also known as Nitinol, to other tubular components. Such mechanical joining may be achieved by interpenetration of lobe features between the respective tubes by translating the tubes together on a longitudinal axis, a transverse axis, by a combination of translation and rotational motion or by a hinging motion. The Nitinol superelasticity is used to accommodate the lobe deformation required for assembly and to snap the lobe back into its original shape to complete the mechanical joint.Type: GrantFiled: December 17, 2018Date of Patent: January 30, 2024Assignee: VIANT AS&O HOLDINGS, LLCInventors: Mark W. Broadley, Michael D. Wood, Jim D. Cooney, Timothy Hoklas

Patent number: 11543066Abstract: Composite tube assemblies and thin-walled tubing are disclosed. In embodiments, the composite tube assemblies include a functional tube and a sacrificial tube disposed within or around the functional tube. The sacrificial tube may be removed by exposure to a corrosive media, without substantially affecting the functional tube. Methods of forming composite tube assemblies and thin-walled tubing are also described.Type: GrantFiled: June 3, 2019Date of Patent: January 3, 2023Assignee: VIANT AS&O HOLDINGS LLCInventors: Mark W.

Patent number: 11253917Abstract: Material processing systems are disclosed. Some systems include methods of eliminating or reducing defects in elongate workpieces that can undergo large deformations during processing. Some systems include apparatus configured to facilitate such large deformations while maintaining internal stresses (e.g., tensile stresses) below a threshold stress. Some disclosed systems pertain to powder extrusion techniques. Continuous and batch processing systems are disclosed.Type: GrantFiled: March 21, 2018Date of Patent: February 22, 2022Assignee: VIANT AS&O HOLDINGS, LLCInventors: Mark W.

Patent number: 10751644Abstract: A multi-walled tube that is useful as an analytical column in which chemical mixtures can be separated into their individual components is described. In order to be acceptable as an analytical column, the inner surface of the multi-walled tube must support effective separation, but not react chemically with or contaminate the solvent or the analyte (sample to be separated). Grade 316 stainless steel is typically preferred for this purpose. Moreover, the inner diameter (ID) surface of the multi-walled column is preferably very smooth (less than 10 micro inch Ra) with no interruptions in the surface such as scratches, pits, or asperities. However, since the column is designed to be attached to chromatographic equipment using standard size connection features, the size of standard fittings define the outer diameter (OD) of the column.Type: GrantFiled: January 29, 2018Date of Patent: August 25, 2020Assignee: VIANT AS&O HOLDINGS, LLCInventors: Mark W. Broadley, John K. Eckert

Publication number: 20180029129Abstract: A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.Type: ApplicationFiled: October 12, 2017Publication date: February 1, 2018Inventors: Mark W.

Publication number: 20100178194Abstract: The present invention provides a continuous powder extrusion method for making an article having a profile including an outer shape and optionally including one or more inner hollows. One or more bulk material powders and one or more binders are provided, and the bulk material powders and the binders are mixed to form a mixture. A die is provided, the die optionally including a mandrel having one or more shapes. The mixture is extruded through the die and the optional mandrel to produce a green form. The green form is debound to produce a brown form and the brown form is sintered to produce a densified form. The densified form is optionally processed using thermal, mechanical, and/or thermomechanical processing to produce a wrought form. The densified or wrought form is optionally cut to a length and/or finished using traditional metal finishing processes.Type: ApplicationFiled: January 12, 2009Publication date: July 15, 2010Applicant: Accellent, Inc.Inventors: Mark W.

Patent number: 7360442Abstract: The present invention is a method for measuring and calculating tensile elongation of ductile metals on small diameter specimens. The method includes marking a tensile specimen with a pattern of gage markings at predetermined intervals. The tensile specimen is pulled to failure and then fitted together at the fracture. Distances between corresponding markings straddling the fracture are measured extending progressively outward from the fracture. From the measurements, elongation as a function of gage length is determined. End point elongation values (i.e., elongation at zero or near zero and infinite or very long gage lengths) are also determined. Determined elongations are scaled to reflect the values that would have been generated on a standard 0.5 inch diameter specimen. Based on the scaled elongation as a function of gage length and the end point elongation values, a value of elongation can be determined that represents a material property for FEA modeling the plastic strain behavior of a device.Type: GrantFiled: December 29, 2005Date of Patent: April 22, 2008Assignee: Accellent, Inc.Inventors: Mark W.
