20090078440 | Flexible tubing with imbedded helical conductors and method of making - A smooth-bore plastic tubing with helical support bead is resistant to collapse and incorporates plural electrical conductors outside of the tubing bore and insulated from ambient, and from one another. The conductors may have a desired relatively high thermal conductivity to tidal air flow within the tubing, while also having a comparatively high thermal resistance to ambient. A method for making the tubing includes extruding a molten thermoplastic ribbon with an elevated plateau portion defining plural conductor-receiving grooves. The plastic ribbon is wrapped to form a tube and plural conductors are embedded in the grooves of the plateau portion. A molten thermoplastic bead is then applied atop the plateau portion providing a smooth-bore unitary flexible tubing structure with both inside and outside surfaces which are substantially free of crevices or recesses which could retain soil or bacteria. | 03-26-2009 |

20120125652 | Umbilical for subsea installation - An umbilical for subsea installation has a core of at least two longitudinal elements like cables, tubes and solid and/or hollow filling elements and a cover surrounding the core. At least one of the hollow filling elements is provided with several perforations and the cover is permeable for sea water, thereby allowing seawater to fill the interior of the filler elements as well as the interstices between the cable, tube and the filler elements and the cover when the umbilical is submerged. | 05-24-2012 |
20120152584 | Device for Preventing Electrically Induced Fires in Gas Tubing - The present invention provides gas tubing that is resistant to electrical insult. The gas tubing includes an inner Corrugated Stainless Steel Tubing (CSST) and a shunt that surrounds the CSST. This shunt may be a mesh or solid metal layer and is conterminous with the CSST and has a higher conductivity than the CSST. The shunt mesh increases the charging rate of the gas tubing in the presence of electric charge above that of CSST, thereby reducing electrical potential differences between the gas tubing and adjacent structures in the presence of electric charge. This reduced potential difference reduces the likelihood of electrical arcing from such adjacent structures to the gas tubing during events such as lightning strike. | 06-21-2012 |
20120160536 | FLUID CONNECTOR WITH HOSE CUTTING RING - An electrically conductive hose cutting ring is shaped to provide a cutting edge for penetration of the inner layer(s) of a multiple layer fluid conveyance hose when it is forced onto a fluid connector. The cutting action by the cutting blade provides for a relatively low resistance electrical connection between an electrically conductive layer of the hose and the fluid connector. This can be used to provide a signal path from a sensing element on the hose to a system electronic component. | 06-28-2012 |
20120255758 | Extension Hose for Vacuum Cleaners - The present invention relates to an extension hose for a vacuum cleaner, which includes a female connector mounted at one end thereof and a male connector mounted at other end thereof so that a flexible hose of the vacuum cleaner can be extended, thereby improving a convenience in use. | 10-11-2012 |

The hose being releasably connectable to a fluid receiving entity to provide fluid to said entity. The fluid conveying hose has a wall defining a fluid carrying tube and a power and/or data transmission cable integrated into that wall. The user definable module is connectable to the cable and has components to measure at least one measurable parameter at the end of the hose and/or provide electrical connection between the cable and said fluid receiving entity for the transmission of data and/or power along the hose via said user definable interface. Also disclosed is a method of configuring a hose for fluid transfer. The method includes the step of selecting a user definable module and attaching the selected module to a distal end of the hose prior to connecting said hose to a fluid receiving entity. | 10-03-2013 |

20140262413 | Impedance Controlled Subsea Ethernet Oil Filled Hose - One or more insulated conductive wire assemblies are incorporated in a pressure balanced, oil-filled (PBOF) hose. Each conductive wire assembly has a pair of conductive wires each having an insulation layer, an insulating material surrounding the insulated wires, and an outer insulating layer surrounding the insulating material. The insulating material may be selected to have a dielectric constant substantially matching the dielectric constant of the oil in the PBOF hose, so that the insulated pair of conductors perform in the same way both before and after the assembly is submerged in oil in the jumper hose. One or more parameters of the conductive wire assembly are selected such that the assembly has a predetermined impedance when submerged in oil within the PBOF hose. | 09-18-2014 |
