A process produces an electrical line which extends in the longitudinal direction and the line has a line core and an outer shell. In a continuous shaping process, individual shell portions of the outer shell are formed successively by surrounding the line core with a curable plastic substance. In at least one portion, the outer shell is produced having a cross-sectional geometry which can be varied in the longitudinal direction of the line.

The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process. Embodiments of the present disclosure provide a unidirectional cooling element having a unidirectional cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube. The unidirectional cooling element operably expels cooling gas in a path with the flow of the molten film tube toward an exit gap formed between the unidirectional cooling interface and the molten film tube. The minimum gap between the unidirectional cooling interface and the molten film tube occurs at the exit gap, and advantageously, the unidirectional cooling interface is provided with one or more compound angles to maximize stability and cooling efficiency.

Provided is a method for producing a packing sheet with improved insulation and storage properties, which can greatly reduce logistics costs by minimizing a volume during storage and transportation and also greatly increase insulation.

The invention involves a system and method for constructing lawn furniture. The system includes box type beam members as well as a large box structure supported above a ground surface. The box structure provides rigidity and stability to the furniture while also functioning as storage space. The components are formed to ship in a dissembled compact state and snap together with minimal use of fasteners and tools.

A method is provided for producing a corrugated tube that has, at least in sections, first outer wall regions with a first external diameter and second outer wall regions with a second external diameter that alternate in a wave-shaped manner. The first external diameter is greater than the second external diameter. The corrugated tube is produced by a plastic vacuum/blow molding process in a plastic vacuum/blow mold with a corrugator (1). One or more openings are made in at least some of the first outer wall regions. The openings are made in at least some of the first outer wall regions of the corrugated tube during the plastic vacuum/blow molding process within the corrugator (1).

A method of sub-ambient pressure processing of blow-molded polymer foams and skin-over-foam sandwich panel configurations for lightweight components having improved structural properties. The method can create either skinned or un-skinned foams that offer smooth interior and exterior surfaces, zero or controlled surface porosity, skins of pre-defined thickness, and foam cells that are expanded and oriented normal to the material plane, effectively spherical or polyhedral in nature, and offering improved bending and compressive strength.

The invention is generally directed to sports bottles and other articles produced by blow molding from polymeric materials containing isosorbide having glass transition temperatures ranging from 90 C. to 130 C., as well as to processes for producing them. These articles can be exposed to water at high temperatures and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20 C. greater than the glass transition temperature (Tg) of the polymeric material.

A filler tube, which is capable of satisfying required functions suitably in compliance with the bellows and non-bellows cylindrical base while securing weld strength and fuel-permeation resistance property in the weld face, is provided. A filler tube includes a non-bellows cylindrical base with a total thickness of from 2 to 4 mm, a bellows with a total thickness of from 0.5 to 3 mm, and a flange having a total thickness of from 3.5 to 5 mm, and including an end face to be welded to a fuel tank. The non-bellows cylindrical base, the bellows, and the flange include inner layers formed so as to have a thickness accounting for from 40 to 60% of the total thicknesses, and formed of high-density polyethylene (or HDPE) serving as the major constituent, intermediate layers exhibiting fuel-permeation resistance property, and outer layers protecting the intermediate layers.
