A fishing jig is disclosed. The fishing jig includes a semitransparent skirt having a generally tubular body that extends between a closed head end and a tail end that includes an opening. A channel is formed within the tubular body and extends from the opening toward the head end. The fishing jig also includes a jig head positioned within the channel of the skirt and at least partially visible through the skirt. The jig head may include a body having a first side and a second side, an eye positioned on each of the first side and the second side, the eyes being visible through the skirt, and a hook that extends from the body and through the opening in the skirt. The fishing jig may mimic the look and motion of bait fish.

ALUMINUM ALLOY HAVING VISIBLE GRAINS AND ALUMINUM ALLOY COLORED BY DOUBLE ANODIZATION
20190062885 · 2019-02-28 ·

Embodiments relate to a type of aluminum alloy with grains visible to naked eyes. The aluminum alloy may have an average grain size of at least 100 m. The aluminum alloy can be produced by a process such as casting, extrusion, solutionizing, aging, and etching. The solutionizing causes recrystallization of aluminum and causes grains of the aluminum to grow. Compared with the solutionizing, the aging is performed at lower temperature but enhances strength of the aluminum alloy. The etching makes grain boundaries of the aluminum alloy more prominent, rendering the grains of the aluminum alloy visible to a naked human eye.

HYBRID PART OVER-MOLDING PROCESS AND ASSEMBLY
20190060989 · 2019-02-28 ·

A method of over-molding a hybrid sub-assembly onto a base structure includes providing a mold for an over-molding process. The mold may comprise a lower mold tool, an upper mold tool, and a tube locator positioned on one of the upper mold tool or lower mold tool. A base structure formed of a first material is located into the tube locator. A mandrel tool is inserted into an opening in the base structure. The upper and lower mold tools are closed and clamped shut. A second material, such as a lighter weight or lower density material is heated to at least a semi-solid or slurry state. The semi-solid or slurry is injected into the mold to form a molded sub-assembly that is mechanically bonded to the base structure.

Galvanically-Active In Situ Formed Particles for Controlled Rate Dissolving Tools
20190054523 · 2019-02-21 ·

A tastable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

Insert part that can be infiltrated

An insert part for a cast piston of an internal combustion engine may include a powder, such as a sintered powder material, containing at least iron or alloys thereof, and having a capacity for being infiltrated. The powder may contain particles having different grain sizes, and up to 4% by volume of the powder may include particles having a diameter smaller than 75 m.
