Patent number: 11243144Abstract: A sampling container assembly includes a sample receiving residue tube, a residue tube cap, inner and outer pipes, a container cap, a fixture block, and a supply conduit. The residue tube cap is assembled with the residue tube and defines inlet and outlet ports. The inner pipe has a lower end sealingly mounted to the fixture block and surrounding the residue tube to define an inner cavity for receiving a heat transfer fluid. The outer pipe has a lower end sealingly mounted to the fixture block and surrounding the inner pipe to define an outer annulus, with the container cap sealingly assembled with an upper end of the outer pipe. The supply conduit extends through the fixture block and the outer annulus and is connected with the inlet port of the residue tube cap for providing a sample fluid to the residue tube. The fixture block defines a passage extending to the outer annulus for supplying a chilling fluid to the outer annulus for chilling the heat transfer fluid in the inner cavity.Type: GrantFiled: March 26, 2020Date of Patent: February 8, 2022Assignee: Swagelok CompanyInventors: Matthew Dixon, Eric M.

Patent number: 10648596Abstract: In a method of assembling a conduit fitting, a conduit fitting is provided, including a first coupling member, a second coupling member, an internal conduit gripping device disposed between said first coupling member and said second coupling member, and an external deformable structure. The first coupling member is pulled up with the second coupling member on an end portion of a conduit to engage the external deformable structure with an external surface of one of the first and second coupling members. After engaging the external deformable structure with the external surface of one of the first and second coupling members, the first coupling member is further pulled up with the second coupling member to axially compress the external deformable structure, until an amount of torque required to continue pulling up the first coupling member increases to a predetermined torque. The predetermined torque corresponds to an initial pulled-up position in which the conduit gripping device grips and seals the conduit.Type: GrantFiled: February 8, 2018Date of Patent: May 12, 2020Assignee: SWAGELOK COMPANYInventors: Mark D. Bearer, Mark A. Bennett, John D. Karkosiak, Jeffrey Michael Rubinski, Peter C. Williams, Tobin Berry, Mark A. Clason, Eric M. Kvarda

Publication number: 20150362101Abstract: A ferrule type, flareless fitting is provided that may optionally be pulled-up to its assembled condition by torque rather than by turns. In one embodiment, at least one fitting component includes a structure that facilitates pull-up by torque and allows the fitting to be remade. The structure may take a wide variety of different forms. Examples of fitting component structures that facilitate pull-up by torque and allow the fitting to be remade include, but are not limited to, deformable or compressible devices or structures that are configured to increase the torque required to further tighten the fitting components when the fitting is properly pulled up, resiliently deformable structures that bias a tube gripping device into engagement with a conduit when the fitting is remade to an initial pull-up position, and plastically deformable retaining structures that maintain a tube gripping device in sealing engagement with a conduit when a fitting is disassembled.Type: ApplicationFiled: March 19, 2015Publication date: December 17, 2015Inventors: Mark D. Bearer, Mark A. Bennett, John D. Karkosiak, Jeffrey Michael Rubinski, Peter C. Williams, Tobin Berry, Mark A. Clason, Eric M. Kvarda

Publication number: 20120318373Abstract: A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.Type: ApplicationFiled: May 24, 2012Publication date: December 20, 2012Applicant: Swagelok CompanyInventors: Jared S. Timko, Thomas A. Lippucci, Eric M. Kvarda, Brandon J. Fry, James E. Gotch
