| 20120090720 | FLUID RESISTANT HIGH TEMPERATURE HOSE - The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology. The present invention more specifically discloses a hose which is comprised of (1) an elastomeric tubular inner core layer defining a lumen, (2) a friction layer, and (3) an elastomeric cover, wherein the elastomeric tubular inner core layer is comprised of (i) a chlorinated elastomer selected from the group consisting of epichlorohydrin, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, (ii) 1 phr to 50 phr of a chlorinated paraffin, and (iii) 30 phr to 120 phr of carbon black. It is typically preferred for the chlorinated elastomer to be chlorinated polyethylene or chlorosulfonated polyethylene. | 04-19-2012 |

Additional layers also provide increased damage resistance after the outer layers of fabric are worn away, and added layers improve wear resistance on the sides of the lugs due to undercarriage misalignment and track-to-wheel contact when the vehicle turns during normal operations. | 05-26-2011 |

| 20100055363 | COMPRESSION RESISTANT FLOATING HOSE FOR REELING APPLICATIONS - Floating hose is normally comprised of a carcass that is covered with a layer of foam to provide buoyancy. The foam can be deformed and compressed by being repeatedly reeled onto a drum under conditions of high axial forces (reeling forces plus hose weight). The propensity for the foam layer to become compressed is aggravated in typical conditions where the hose is stored on a reel for extended periods and is on the reel more than it is in the water. In any case, compression damage causes the hose to lose buoyancy which can ultimately result in the hose sinking under conditions of normal use. It would accordingly be desirable to develop a floating hose that minimized the permanent damage caused by the foam layer being compressed to high levels over and over again. The floating hose of this invention is resistant to damage that can be caused by axial forces, such as those encountered while being collected on a reel. More specifically, the floating hose of this invention is not as susceptible to being damaged by compression as conventional floating hoses. This is by virtue of the floating hoses of this invention including anti-compression collars that protect the floatation medium therein from damage that can occur during routine usage. This extends the service life of the floating hoses of this invention and reduces their propensity to lose buoyancy over time. The present invention more specifically discloses a floating hose comprising: a carcass having an inside and an outside; a plurality of anti-compression collars interspaced around the carcass; a floatation medium surrounding said hose carcass and said anti-compression collars, and an outer cover, wherein said outer cover covers said floating medium and said anti-compression collars. | 03-04-2010 |
