A self-healing elastomeric compound for use in blowout preventer packers includes one or more elastomers, carbon black, silica, and a self-healing agent evenly distributed throughout the compound.

Blowout-preventers (BOP) elastomer seals with improved self-healing

An apparatus is disclosed as including a first material volume with at least a hardened portion and a second material volume that includes at least two layers. The first material volume is composed of at least a hardenable alloy of steel. The at least two layers is located adjacent to a first surface comprising the hardened portion of the first material volume. The at least two layers includes a first layer composed of at least a ductile low-carbon alloy of steel and a second layer composed of at least a cobalt-based hardfacing over the first layer. The apparatus is applicable in preparing shear ram blocks and shear ram blades to provide a hardened blade edge with an adjacent hardfacing surface.

Hardfaced metal surface and method of manufacture

A method for making a compartmentalized sealant strip and barrier assemblyhas the steps of co-extruding a barrier stripof non-sealant elastomeric material with a plurality of projecting linear extending wallsand a sealant stripwherein the sealant stripis formed on one side of the barrier stripfilling the space between the plurality of projecting wallsto form a plurality of linearly extending rows of sealantacross the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly. The step of co-extruding may further include the step of: forming the projecting wallson an inclined angle relative to a plane perpendicular to the width of the assembly. The step of co-extruding further has the step of forming the barrier stripwith lateral edgesandthat extend beyond the lateral outermost sealant stripson each side of the assembly, the lateral edgesbeing bonding surfaces to seal the sealant strip and barrier assemblyinto an uncured rubber layer when assembled into an unvulcanized tire

Embodiments of a method for monitoring an annular packer are provided herein. In some embodiments, a method for monitoring a sealing element of a blowout preventer may include providing a fluid to a chamber disposed within a blowout preventer to actuate a piston disposed within the chamber, wherein the actuation of the piston causes a reduction of an inner diameter of a sealing element; measuring one or more parameters of the fluid via a sensor; receiving data relating to the one or more parameters from the sensor; determining a stiffness of the sealing element utilizing the data relating to the one or more parameters; and determining an amount of degradation of the sealing element by comparing the determined stiffness of the sealing element to a known data profile.

A composite material comprises a plurality of springs forming a structure embedded within a polymer. Each spring is interwoven with at least one other spring thereby forming an entirely polymer-coated structure.

Non-pneumatic tire

A variable ram packer has an elastomeric body having a central semi-cylindrical recess and wings extending from opposite lateral sides of the recess. Inserts are positioned around the recess, each having an upper plate, a lower plate and a web joining the plates. Inserts at the junction with the wings have barrier plates between and parallel with the upper and lower plates. Upper and lower wing plates are located on upper and lower surfaces of the wings. An adhesive layer on an outer portion of each of the wing plates bonds the wing plates to the elastomer of the body. Each wing plate has an inner portion in abutment with the elastomer and free of the adhesive layer.

A method for recovering uncured rubber from unused electron beam pre-cured rubber stock used in the manufacture of pneumatic tires. A first layer of the pre-cured rubber stock having cured rubber is skived with a band knife cutter blade from a second layer of the pre-cured rubber stock having uncured rubber. The band knife cutter blade is lubricated so as to avoid adhesion of the uncured rubber to a leading cutting edge of the cutter blade. After the first layer of cured rubber is removed from the pre-cured rubber stock, the uncured rubber in the second layer is reworked into at least one tire component.

Method for recovering uncured rubber and tire including reclaimed rubber

The present invention relates to a tire containing a layered composite of sealant and air permeation resistant film, particularly a non-elastomeric film.

Tire containing layered composite of sealant and air permeation resistant film

An assembly for use in or on a tire. The assembly comprises an electronic device having a body and an adhesive coating on at least the body of the electronic device. The body is at least partially made of a plastic material or a fiber reinforced plastic (FRP). The adhesive coating comprises an imide-based adhesive. The adhesive coating may have a polymer bonding group comprising at least one of natural rubber, butyl rubber, a chlorinated elastomer, polybutadiene, synthetic polyisoprene, or styrene-butadiene rubber or a combination thereof. In one embodiment, the assembly further comprises a first elastomeric layer and a second elastomeric layer. The adhesive coating secures the body to the first and the second elastomeric layers. The first and second elastomeric layers may comprise a butyl-containing compound or natural rubber compound. In one embodiment, the electronic device is a radio frequency identification tag having the body and an antenna.

Environmentally resistant assembly containing an electronic device for use in a tire

The present invention relates to a tire puncture sealant and a pneumatic tire containing such puncture sealant as a built-in puncture sealant. The sealant composition contains silica reinforcement and butyl rubber depolymerized in the presence of a balanced and cooperative combination of organoperoxides comprised of a minor amount of 4,4-di(tertiary butylperoxy) valerate depolymerization initiator and a major amount of dicumyl peroxide depolymerization propagator, the combination of which has been observed to have a synergistic effect.

Tire sealant and tire with sealant containing silica and balanced organoperoxide depolymerized butyl rubber

The present invention relates to a pneumatic tire which contains a built-in zoned puncture sealant layer. The zoned puncture sealant layer is comprised of organoperoxide depolymerized butyl rubber zones comprised of a central primary zone and lateral zones joined together to form a unitary sealant layer. The sealant of the lateral zones of the sealant layer is of a higher storage modulus (G') than the sealant of the central zone.
