Patent number: 11754185Abstract: A metal O-ring is provided. The metal O-ring has a sidewall with an outer surface and an inner surface. The outer surface of the sidewall is machined to selectively thinning the thickness of the sidewall, such that the sidewall of the of the metal O-ring has a plurality of thicknesses equal to or less than a maximum thickness and equal to or more than a minimum thickness. Selectively thinning the sidewall by machining the outer surface allows for control of the elasticity of the metal O-ring. Controlling the elasticity of the metal O-ring, and potentially increasing the spring back, may provide for increased contract pressure at a sealing interface, which would facilitate sealing. The machined outer surface of the metal O-ring are generally machined to flat surfaces.Type: GrantFiled: August 18, 2021Date of Patent: September 12, 2023Assignee: Technetics Group LLCInventors: Mark S. Whitlow, James S. Hicks, Florent Ledrappier, Jean-Francois Juliaa, Christophe Darles

Patent number: 10598284Abstract: An annular seal comprising a metallic ring having a cross section. The cross section includes an axially extending body portion having a radial width and an axial height. A spaced apart pair of sealing arms extend axially from the body portion, wherein each sealing arm includes a radially opposed arcuate sealing surface. The arcuate sealing surface may be convex, for example. The spaced apart pair of sealing arms are spaced apart a radial distance greater than the radial width of the body portion. A sealing system comprises a plurality of interconnected metallic rings wherein the body portion engages the sealing arms of an adjacent metallic ring.Type: GrantFiled: October 19, 2017Date of Patent: March 24, 2020Assignee: TECHNETICS GROUP LLCInventors: Mark S.

Publication number: 20150159755Abstract: A resilient metal seal that includes a PTFE jacket or liner capable of improving the sealing performance of the resilient metal seal and providing a near chemically inert surface to protect the seal from coming into contact with potentially damaging media is provided. In some embodiments, the resilient metal seal is an E-, U-, C-, or V-shaped resilient metal seal. A jacket made of PTFE or similar material can be included on the interior or exterior surface of the resilient metal seal. The jacket can include a locking feature to prevent against the jacket becoming dislodged from the resilient metal seal.Type: ApplicationFiled: May 16, 2013Publication date: June 11, 2015Applicant: Technetics Group, LLCInventors: Mark S.

Patent number: 8006982Abstract: A high temperature dynamic seal and methods of assembly and use. The dynamic seal is provided as a rotating seal, which includes a stationary ring and rotating ring assembly, with a seal ring that is positioned between the stationary ring member and the rotating ring assembly. One or more high temperature seals create a seal between the stationary ring member and a device in which the dynamic seal is used. Similarly one or more high temperature seals create a seal between the rotating ring assembly and a rotating shaft of the device. One or more of the high temperature seals are formed from a metallic material with various cross-sectional shapes.Type: GrantFiled: March 27, 2009Date of Patent: August 30, 2011Inventors: Mark S. Whitlow, Jeff Noll, Kevin Lamb, Jeffrey D. Farris, Fernando Lopez, Paul Richard Ryan, Roger Sanderson, Mark Vincent Chester, Robert Vincent McGovern
