A sealant forming nozzle is disposed to seal an object that a sectional shape in a first plane is a stair shape. The sealant forming nozzle includes a shaping section and a guide section. The shaping section includes a shaping surface orthogonal to the first plane, and a sealant output hole to supply a sealant to a space surrounded by the object and the shaping surface. The guide section has a guide surface. The guide surface is orthogonal to the first plane and formed to have a line contact with a corner section of an upper step of the stair shape.

In a method of manufacturing an object, a filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The reinforcement portion of the partially molten filament remains in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

A tie-down assembly for a pick-up truck bed that includes a cleat including a base having first and second feet defining first and second fastener receiving holes, a body portion extending from an outer side of the feet, and first and second arms extending from the body portion that are spaced from the feet and define tie-down holes. Fasteners inserted into the first and second fastener holes secure the cleat to the pick-up truck bed. A method of making a tie-down cleat for a pick-up truck bed by extruding an elongated bar having a pair of feet portions connected by a body portion to a pair of arm portions. The elongated bar is cut into a plurality of planar cleat blanks and the cleat blanks are drilled to form fastener holes in the feet portions and tie-down holes in the arm portions.

The invention relates to a fiber optic cable for information transmission, comprised of multiple buffered optical fibers surrounded by aramid yarn within a thermoplastic jacket, produced using a TPE Hytrel buffer, manufactured using a pressure tooling extrusion process. This Hytrel buffering allows for the production of a cable that has a one-third smaller diameter compared to standard PVC buffered distribution cable. Despite this smaller diameter, this invention surpasses the standard PVC buffered distribution cable in both Compressive Load and Impact Testing, and meets Mil-Spec standards.

A cooking apparatus used for filling and decorating of foods, comprising in some embodiments a one-piece, funnel-shaped bag with a soft side wall, having an open first end at the “top” through which food material and coloring agents can be inserted into the bag and a closed second end at the “bottom” end of the funnel, with an integral, malleable, conical shaped, discharge orifice. The orifice may have serrations or ridges extending inwardly from the internal wall of the orifice, running longitudinally or parallel to the cone axis. The orifice may be initially closed or manufactured with a small opening. The orifice may be made of a material capable of being cut to yield an exit opening. The inwardly extending serrations that remain after a cut may insure that the material is “treated” as it is expelled from the bag through the orifice to yield a ribbon candy design.

A system according to various embodiments can include a source for supplying a material to be treated, an extruder, at least two screws, and a drive coupled to the screws for axially rotating the screws. The extruder includes an inlet for receiving the material, which is fed therein in a controlled manner. The screws are provided within the housing of the extruder. The screws have a plurality of compression and release stages that create mechanical heat which is directly applied to the material to change the mechanical properties of the material thereby facilitating a conversion of a physical state of the material from a non-compactable state to a compactable state as the screws rotate and move the material longitudinally along the screws to produce a final product, for example, a feed tub for use as an animal feed.

A decking plank includes a non-distressed surface with a first surface texture defining a plurality of wood grain depressions. The plank also includes a distressed surface with a second surface texture defining a plurality of wood grain depressions and a plurality of cross-grain depressions. An outdoor deck may be formed with the dual-sided deck planks. The deck may be constructed in one configuration where each of the dual-sided deck planks has the distressed surface facing upward and exposed. The deck may be constructed in a second configuration where the same planks are assembled to have the non-distressed surface facing upward and exposed.

A die for a polymer mixing machine includes first and second opposing surfaces. Each defines first cylindrical portions and second V-shaped portions interspaced between each first portion. The first and second opposing surfaces produce a ply with first portions thicker than second portions and throated portions therebetween.
