A reformable, shape retentive hose having a precured tube located in a hose sidewall, and a reformable rod inserted in the precured tube. A method for making hose by placing at least one precured tube in the sidewall of a hose during the time that the hose sidewall is formed, curing the hose assembly with the precured tube in the sidewall, and inserting a reformable rod in a portion of the precured tube.
Metal-plastic multilayer pipe with a plastic inner pipe (30) and a metal sheath (32) around the plastic inner pipe (30), where the metal sheath (32) is of uniform thickness, is applied to the plastic inner pipe (30) so that it completely encircles the plastic inner pipe (30) and a practical plastic outer layer (38), with the feature that the thickness of the metal sheath (32) as compared to the total thickness of all layers of the multilayer pipe (32, 34 and 38), is sufficiently thin that the metal sheath (32) accounts for a negligible part of the overall strength and stiffness of the multilayer pipe and, as a consequence, when the multilayer pipe is bent in an arc, the metal sheath (32) offers negligible resistance to such bending as compared to the resistance offered by the inner pipe (30) and the practical cover layer (38), and when so bent, the multilayer pipe tends to remain bent in said arc, whereby, the multilayer pipe has "form stability".
A shape retention hose construction and method of making the same are provided, the hose construction comprising a length of flexible tubular hose formed mainly of polymeric material and having opposite end portions and an intermediate body portion that defines internal and external peripheral surfaces of the hose, and a shape retention unit carried by the hose and being adapted to generally retain the shape of the hose construction when the hose and its carried shape retention structure are jointly bent into a particular shape, the shape retention unit comprising a deformable elongated member having opposed ends, the hose having a radially outwardly disposed and longitudinally extending projection on the external peripheral surface thereof, the elongated member being longitudinally disposed in the projection, the projection having opposed ends that respectively are disposed inboard of the opposite end portions of the hose, the opposed ends of the elongated member also being respectively disposed inboard of the opposite end portions of the hose, the end portions of the hose respectively having external peripheral surfaces that have substantially circular cross-sectional configurations through-out the axial lengths thereof.
A wand is used to attach to the output of a high-pressure spray gun, with the nozzle or sprayer connected to the other end of the wand. The wand has the characteristics of containing the high-pressure delivered by the spray gun at about 3000 PSI in an internal high-pressure, highly flexible line, which is captured within an external, bendable sheath which retains the shape into which it is bent, so that paint may be more conveniently sprayed in corners and out-of-the-way places.
A liquid removal system particularly adapted to remove water from a gas main. The system includes the combination of highly flexible, low-friction tube fitted with an internal stainless steel stiffener, this assembly having a weighted nose guide to ensure that the assembly remains at the bottom of the gas main. The assembly is inserted into the gas main through a tap hole using an insertion guide to ensure that the assembly is inserted at a proper angle into the gas main.
A garden hose assembly is provided and comprises holding means comprising at least a portion of such hose assembly with the holding means and portion being adapted to be coiled around an associated support for holding the portion at a desired position to enable use of the hose assembly in a hands-free manner.
