A polycrystalline super hard construction has a first region having a body of thermally stable polycrystalline super hard material having a plurality of intergrown grains of super hard material; a second region forming a substrate having a hard phase and a binder phase; and a third region interposed between the first and second regions. The third region includes a composite material having a first phase comprising a plurality of non-intergrown grains of super hard material, and a matrix material. A fourth region interposed between the second and third region has a major proportion having one or more components of the binder material of the second region, and one or more reaction products between the binder material of the second region and one or more components of the third region.

Apparatus and associated methods relate to using an additive (material deposition) process to incrementally form a closed-cell lattice structure formed as a unitary body in the shape of a marine hull cavity, the unit cells of the closed-cell lattice structure are substantially hollow. In an illustrative example, a method may include (a) forming a closed-cell lattice structure through additive manufacture, the hull cavity material may be bonded to an upper manufactured liner and a lower manufactured liner through lamination or mechanical connection. Unit cells of the closed-cell lattice structure may include hollow voids filled with gases. Providing the additive manufactured closed-cell lattice structure with a unitary body and hollow voids to trap gases may further advantageously promote the buoyancy and reduce the degeneration of a marine hull.

A three-dimensional additive manufactured product includes a body portion and a male screw portion integrally disposed on a surface of the body portion so as to protrude therefrom. The male screw portion includes a following side flank forming a first flank angle with respect to a vertical plane to an axis thereof. The first flank angle is not less than 45 degrees.

A method for connecting a first component to a second component to form an assembly forms a press fit connection between the first component and the second component, for which purpose the second component is produced having an annular component section. A recess is formed, in which the first component is at least partially arranged. At least the annular component section of the second component is produced as a sintered component and has net shape or near net shape quality at least in the region of the recess.

The present invention relates to a film-shaped firing material (1) which contains: sinterable metal particles (10); a binder component (20) that is a solid at room temperature; and a liquid component (30) that is a liquid at room temperature, the liquid component having a boiling point from 300 to 450° C.

A composite fiber composed of at least a metal sintered body and a ceramic sintered body. In the composite fiber, the metal sintered body and the ceramic sintered body are adjacent to each other. The composite fiber having the metal sintered body and the ceramic sintered body can have a tensile strength of 5 kgf/mm.sup.2 or more.

A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

A cutting tool includes a body configured to rotate about a longitudinal axis, a blade connected to the body, and a pre-formed segment. The blade extends away from the body and includes a recess formed in a leading face of the blade. The pre-formed segment is disposed in the recess adjacent to the leading face of the blade. The pre-formed segment is connected to the blade. The pre-formed segment includes a cutter pocket therein, the cutter pocket having a sidewall and a base.
