Apparatus and Method to Repair the Junction of a Sewer Main Line and Lateral Pipe
A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.
Processing for Producing Flexible Container with Fitment Using Expandable Mandrel
The present disclosure provides a process for producing a flexible container. In an embodiment, the process includes (A) providing a flexible container. The flexible container has (i) a body, and (ii) a neck. The process includes (B) positioning a fitment into the neck. The fitment has a top portion and a base. The fitment is composed of a polymeric material. The process includes (C) inserting a mandrel into the fitment. The mandrel includes an expandable collar composed of an elastomeric material. The process includes (D) expanding the collar radially outward to contact an inner surface of the base. The process includes (E) sealing, with a pair of opposing seal bars, the base to the neck.
Thermoformed cascades for jet engine thrust reversers
A cascade for a jet engine thrust reverser is fabricated by co-consolidating pre-consolidated thermoplastic strongbacks and vanes. The strongbacks are reinforced with continuous fibers, and the vanes are reinforced with discontinuous fibers.
Device And Method For Installing A Tubular Joint Sleeve For A Pipe Comprising An Inner Lining
A device (20) for installing a tubular junction sleeve inside a pipe (1), having a mandrel (20a) of longitudinal axis (XX) supporting on its surface at least a first peripheral chamber (21) having a wall (21a) that is radially expandable by inflation. The first wall including at least one electrical connector (21b) suitable for being connected to one end of said heater wire. The connector being connected to an umbilical (24) including at least a compressed air feed duct for inflating said the first chamber and an electrical power supply duct connected to the electrical connector. The device being characterized in that the mandrel supports on its outer surface a second peripheral chamber (22) having a wall (22a) that is radially expandable by inflation, and also a weld inspection device (23) arranged in the longitudinal direction of the mandrel.
HOLLOW COMPOSITE STRUCTURE AND METHOD OF MANUFACTURING
A method of manufacturing a hollow composite structure is provided. The method includes curing a first portion of the hollow composite structure having at least one open region and at least one wall, the at least one wall partially defining a hollow interior. The method also includes bonding a laminate shell to the first portion of the hollow composite structure proximate to at least one location of the wall to cover the open region and enclose the hollow interior. The method further includes disposing a second portion of the hollow composite structure over the laminate shell, the second portion comprising a plurality of plies. The method yet further includes curing the first portion and the second portion during a final cure.
FLEXIBLE PIPE AND COUPLING THEREFOR
Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.
Method and device for welding casings
The invention relates to a device (1) for producing a case having a large length for food, in particular for sausages, from a plurality of individual case sections made of casings that contain collagens, such as natural casings or collagen-containing artificial casings, comprising a mandrel (2) and at least two sleeve sections (3), wherein the sleeve sections (3), in order to create an overlapping area (4), are pushed over the mandrel (2) and arranged such as to overlap each other, a heating element (5) for temporarily exchanging heat between the heating element (5) and the overlapping area (4), such that the case sections are at least partially welded to each other in the overlapping area (4), a deformable extension body (6), wherein the deformable extension body annularly surrounds the mandrel (2) and is arranged inside the case sections (3), wherein the deformable extension body (6) is made of an elastically deformable material, and a mold (7) that encloses the mandrel (2) in some sections.
Composite structure and method
A composite part includes a first structural element. The composite part includes a second structural element joined at an intersection with the first structural element to form a fillet. The composite part further includes reinforcement webbing wrapped around the first structural element proximate the fillet.
Flexible pipe and coupling therefor
Sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer thereof may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each include a semi-crystalline thermoplastic material. A reinforcement material may be provided in the inner liner layer. In one embodiment the sealing material is injected into the sealing area. In another embodiment the sealing material is provided in the form of meltable ring which fits into the sealing area before fitting of the coupling member, and is activated by an induction heater to effect the sealed connection.
