Publication number: 20120286480Abstract: A “negative creep” corrugated gasket of Shape Memory Alloy (SMA) for Bolted Flanged Connections (BFCs) operates under temperatures that are within the temperature interval of reverse martensitic phase transformation from martensite to austenite of the SMA. Gasket corrugation is shape-memorized to operating “swelling” at temperature of direct martensitic phase transformation from austenite to martensite of the SMA being compressed to obtain some quantity of residual contraction corresponding to stress-induced martensite formation. A free “swelling” of deformed gasket corrugation at operating temperature defines the “negative creep” effect of the gasket, and it is blocked by rigid flanges with appearance of reactive shape-recovering stresses between the gasket corrugation and flange surfaces. The reactive shape-recovering stresses have direction inverse to the direction of operating creep of the gasket providing leak-tight, multiple, automatic and continuous seal between the flanges of the BFC.Type: ApplicationFiled: May 1, 2012Publication date: November 15, 2012Inventor: Anatoly Ivanovich Efremov

Publication number: 20120086175Abstract: A female hydraulic coupling member has an elastomer probe seal molded to or abutting a ring-shaped metal base which is adapted to exert a compressive force on the probe seal when exposed to hydraulic fluid pressure. The compressive force causes the seal to expand in a radial direction thereby increasing its sealing effectiveness. A retainer nut for holding the seal in the receiving chamber may have an angled surface which acts to urge the seal in an inward, radial direction when an axial, compressive force is applied to the seal.Type: ApplicationFiled: December 16, 2011Publication date: April 12, 2012Applicant: NATIONAL COUPLING COMPANY INC.Inventor: Robert E. Smith, III

Patent number: 8087700Abstract: A female hydraulic coupling member includes a bidirectional, pressure-energized probe seal for sealing between the body of the female coupling member and the cylindrical probe section of a male coupling member seated in the receiving chamber of the female member. In one embodiment, the pressure-energized seal comprises a first curved section which is oriented towards the external end of the receiving chamber in which it is installed and a second curved section oriented towards the interior end of the receiving chamber. The two curved sections are joined by a substantially straight back section. When the pressure of fluid within the coupling member is above the ambient fluid pressure, the first curved section is pressure-energized so as to increase its sealing effectiveness. When external pressure (e.g., the hydrostatic head) exceeds the pressure of fluid within the coupling member, the second curved section is pressure-energized so as to increase its sealing effectiveness.Type: GrantFiled: March 27, 2009Date of Patent: January 3, 2012Assignee: National Coupling Company, Inc.Inventor: Robert E. Smith, III

Patent number: 8074996Abstract: An sealing gasket is shown for use in forming joints of plastic pipe. The gasket has a bulbous region which is bisected by a planar region which forms a pair of oppositely extending wing-like flaps. These features of the gasket allow it to be more reliably seated on the working mandrel used to bell a female, thermoplastic pipe end. The wing-like flap portions of the gasket form wiper surfaces for a subsequently installed male, spigot pipe end as the joint is formed.Type: GrantFiled: June 6, 2008Date of Patent: December 13, 2011Assignee: S & B Technical Products, Inc.Inventors: Gerardo Darce, Randall Chinchilla
