11/13/14 - 20140332111 - Reinforcing assembly for air conditioning ducts and reinforced air conditioning duct incorporating such assembly
A reinforcing assembly for an air conditioning duct comprises a plurality of annular elements having outer circumferences configured to define an inner cross section of the conditioning duct, at least three interconnecting cords for linking the outer circumferences of the annular elements in a series, and fixing means for securing...

05/08/14 - 20140124082 - Pipeline reinforcement assembly and method
An assembly and a method for reinforcing or repairing one or more segments of an existing pipeline, without taking the pipeline out of service and without the need for disassembling the existing pipeline segments that are to be repaired. The assembly incorporates a metallic reinforcement pipe, a front seal ring,...

02/06/14 - 20140034180 - System for relieving stress at pipe connections using external sleeve
A pipe attachment assembly for attaching a pipe to another structure so stresses are reduced within the assembly includes a sleeve positioned outside the pipe which is composed of a material stronger than the pipe material, and an elastomeric bonding material which fills a gap between the pipe and the...

01/09/14 - 20140007971 - Pliable-wall air ducts with internal expanding structures
Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes a shaft to be disposed within an air duct, to extend in a longitudinal direction, and to be in longitudinal compression. The air duct system also includes a plurality of ribs to be coupled to...

05/09/13 - 20130112310 - Pipeline reinforcement assembly and method
An assembly and a method for reinforcing or repairing one or more segments of an existing pipeline, without taking the pipeline out of service and without the need for disassembling the existing pipeline segments that are to be repaired. The assembly incorporates a metallic reinforcement pipe, a front seal ring,...

03/28/13 - 20130074974 - Ductwork stiffener
The ductwork utilized in heating and air conditioning systems is provided with internal crossbars secured to the sides of the duct to prevent inward or outward flexing in response to a pressure differential that could otherwise cause collapse of the sides, either inward or outward, and failure of system. The...

09/27/12 - 20120241040 - Umbilical
An umbilical for use in the offshore production of hydrocarbons, and in particular to a power umbilical for use in deep water applications, is described comprising a plurality of longitudinal strength members, said strength members having one or more varying characteristics along the length of the umbilical. In this way,...

05/17/12 - 20120118424 - Reinforcement and method for tubular structures
A reinforcement and method for reinforcing a hollow tubular structure includes a first sheet of flexible fiber material impregnated with resin. The first sheet is rolled into a tubular shape and a seam is provided between first and second lateral edges of the first sheet to form a tubular reinforcement....

11/17/11 - 20110277868 - Method for repairing and strengthening pipe with internal helically wound tensile reinforcement
A method for repairing and strengthening pipes by creating a structural reinforced composite liner within the existing pipe. The liner is created by helically winding a tensile reinforcement material on the inside wall of a pipe and encapsulating it in a hardening matrix material. The reinforcement material is helically wound...

10/27/11 - 20110259463 - Viscoelastic damped jumpers
A system, in certain embodiments, includes a multi-layer composite strip of pipe dampening materials, comprising a first layer of a first material, a second layer of a second material disposed adjacent to the first layer of material, and a third layer of a third material disposed adjacent to the second...

04/08/10 - 20100084038 - Soft crack arrestors for pipelines
An arrestor for arresting an axial ductile propagating fracture in a pipeline transporting a high-energy fluid is made from a material such that the arrestor deforms sufficiently when encountering a propagating fracture that the propagating fracture continues at least under the arrestor but the arrestor has enough strength that it...
