The wound element imparts corrugations to the two sleeves, such that the duct is extendible between a compacted configuration suitable for storage and for shipping and an extended configuration suitable for installation in a gas transport arrangement. Both the inner sleeve and the outer sleeve are of a predetermined thickness rendering the duct substantially rigid when in an extended configuration and enabling the duct to maintain its substantial rigidity upon extension from a compacted configuration. Optionally, at least one of the sleeves further includes a second, plastic layer bonded to the aluminum foil ribbon layer. | 06-24-2010 |
| 20100224276 | Flexible, stretchable, crush resistant hose well suited for medical applications - A flexible, stretchable, crush resistant hose particularly well suited for supplying breathing gases to patients in medical applications and the like has a helix defined by coils of thermoplastic material, and a web of thermoplastic material bonded or welded to adjacent ones of the coils, preferably along inner diameter portions of the surfaces of the coils. The web extends radially outwardly from between the adjacent coils to define a helical reverse-direction crease at a maximum outer diameter of the hose when the hose is in a normal minimal-length condition wherein the coils are situated side-by-side sandwiching portions of the web therebetween. The thermoplastic material of hose is stress relieved by an annealing process after the hose is formed, to enhance the flexibility of the hose and the ease with which the hose can be extended. | 09-09-2010 |
| 20110277865 | AXIALLY COMPRESSIBLE FLEXIBLE TUBING AND METHOD FOR MAKING SAME - A length of flexible helically corrugated rubber tubing is provided with certain characteristics that enable it to be axially compressed to less than half of its normal relaxed length using minimal force while still providing a high resistance to crushing. The tubing has a wall with a uniform thickness, the wall defining external and internal threads with a specially defined pitch and thread height related to the wall thickness. | 11-17-2011 |
| 20130037159 | REINFORCED FLEXIBLE TUBING AND METHOD OF MAKING SAME - A method for making helically corrugated rubber tubing with a helical reinforcing element embedded therein and with a relatively smooth interior surface. The tubing is formed with separate inner and outer tubular wall portions with fabric material in between. The inner and outer wall portions may be formed of different elastomeric compositions. Also the method provides for annular cuffs at the opposite ends of the tubing. | 02-14-2013 |
| 20140130931 | FLEXIBLE STRETCH HOSE HAVING INWARDLY EXTENDING WEB PORTIONS CONNECTING ADJACENT PAIRS OF REINFORCING COILS, WITH HOSE PROPERTIES ENHANCED BY ANNEALING - A flexible, stretchable, crush resistant hose particularly well suited for supplying breathing gases to patients in medical applications and the like has a helix defined by reinforcing coils of thermoplastic material, and a web of thermoplastic material bonded or welded to adjacent ones of the coils, preferably near outer diameter portions of the coils. The web extends radially inwardly between the adjacent pairs of the reinforcing coils to define a helical reverse-direction crease that can be located closer to or farther from a centerline of the hose than is the inner diameter of the reinforcing coils. The thermoplastic material of the hose is stress relieved by an annealing process performed during axial compression of the hose at a time after the hose has been formed. | 05-15-2014 |
| 20140332108 | Stretch hose and hose production method - An extensible-retractable helically reinforced hose is formed by helically wrapping a freshly extruded bead of thermoplastic material about a rotating mandrel to form a helical array of spaced reinforcing coils, and by helically wrapping a freshly extruded thin yet wide web of thermoplastic material so edge regions of the wide web are placed onto and bond continuously with the peripheries of each adjacent pair of the reinforcing coils, with a leading edge region of each new wrap of the web overlying and bonding to a trailing edge region of a prior web wrap. Central portions of each web wrap extend radially inwardly and are sandwiched between adjacent reinforcing coils when the hose is retracted to a minimal axial length. | 11-13-2014 |
| 20140338776 | FLEXIBLE PIPE BODY AND METHOD - Flexible pipe body and method of manufacturing a flexible pipe body, the pipe body including a tubular layer ( | 11-20-2014 |
| 20150053299 | UNCOUPLING ELEMENT - In an uncoupling element for uncoupling vibrations of the turbocharger of an internal combustion engine from an exhaust system with a bellows, provisions are made, especially for achieving a lower stiffness with short overall length, for the bellows to be a diaphragm bellows. | 02-26-2015 |
| 20150330535 | LINER FOR CONCRETE ARTICLE - The liner includes a rib formation with a transverse section configured to mechanically lock the liner to a concrete shell and a joint to allow the rib formation to flex. The joint for the rib formation can comprise a first side spaced apart from a second side with each joined to the transverse section to allow each side to flex with respect to each other. The space between the first side and the second side can be filled with a weld material to add rigidity to the rib formation while allowing it to flex. Each of the first side and the second side can be combined at the other end to a shell. The combined rib formation and shell are spirally wound to create the liner. | 11-19-2015 |
| 20150354733 | FLEXIBLE CHIMNEY HOSE LINER - A flexible hose liner is provided having a cylindrical body extending along a longitudinal axis from as first end to a second end. First and second sleeves form the cylindrical body by separate continuous ribbons having a plurality of convolutions formed in a helical pattern along the cylindrical body from the first end to the second end. A ring is formed in each revolution about the longitudinal axis of the continuous ribbon of the first and second sleeves. A plurality of rings form the cylindrical body, each ring has a first convolution and an ending convolution such that a mechanical connection is formed between the ending convolution of a preceding ring and the first convolution of a succeeding ring. The mechanical connection of the between the rings of the first sleeve being different from the mechanical connection of the rings of the second sleeve. | 12-10-2015 |
