Expandable and retractable hose reinforced with hemp
Hemp fibers may be disposed throughout or in selected portions of a hose (e.g., an expandable water hose). The hemp fibers deployed in the hose enhance the durability of the hose, and imparts various advantageous properties (e.g., anti-microbial or anti-bacterial, mildew-resistant, odor reduction, moisture wicking, etc.) to the hose.

HEAT RESISTANT HOSE
A heat resistant hose is described. The hose may include a first outer protective and structural woven reinforcing layer comprising a first tubular fabric structure, a second inner protective and structural woven reinforcing layer comprising a second tubular fabric structure, where the second inner protective and structural woven reinforcing layer is within the first outer protective and structural woven reinforcing layer, a hose innermost extruded waterproofing layer comprising an elastomeric material, the hose layer being bonded to, adhered to, or impregnated into or through the second protective layer, the innermost extruded waterproofing layer is within the inner protective and structural woven reinforcing layer, and an intermediate layer interposed between the first outer protective and structural woven reinforcing layer and the second inner protective and structural woven reinforcing layer, the intermediate layer comprising a fabric laminated with a reflective material.

Woven irrigation tubing, apparatus and method of making same
Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

Method for manufacturing a waterproof felt duct and a waterproof felt duct
A method for manufacturing a waterproof felt duct may include (a) laminating a waterproof film on one side of a first nonwoven fabric and laminating a second nonwoven fabric on the waterproof film laminated on the first nonwoven fabric to form a laminated body; (b) forming a waterproof felt base material by thermally adhering the laminated body; (c) cutting the waterproof felt base material into a desired shape; (d) molding a duct while surrounding the waterproof felt base material cut into the desired shape around the external surface of a molding jig having a worm gear shape; (e) heat-treating the molded duct; (f) cooling the heat-treated duct; and (g) ejecting the cooled duct from the molding jig.
Apparatus and method for terminating flexible pipe body
A method and apparatus are disclosed for terminating flexible pipe body. The apparatus comprises an end fitting core portion (330), an end fitting termination portion (310) and a spacer ring member (335) locatable between the core portion (330) and the termination portion (310) for maintaining a whole anterior end surface of the core portion (330) and an opposed whole posterior end surface of the termination portion (310) in a spaced apart relationship.
