Abstract: There is provided a chain apparatus made at least in part by additive manufacturing. The apparatus includes a pair of spaced-apart annular members. The apparatus includes an elongate member coupled to and extending between the annular members. At least one of the members comprises one or more self-draining internal chambers to allow for removal of residual material therefrom.

Abstract: A reinforced cable tie generally includes an elongate strap, a head attached to a first end of the strap and a continuous fiber reinforcement disposed in and extending substantially continuously along a path defining at least one of the strap and the head. The head has one or more apertures formed therein and a locking device disposed in the aperture of the head. The locking device is configured to permit a second end of the strap opposite the head to be inserted through the head aperture in a first direction and is further configured to prevent movement of the second end of the strap from the head aperture in a second direction opposite the first direction.

Abstract: A thread protector for use with a threaded end of a tubular member comprises a first end having an opening with an inside diameter, a second end, and an interior having an inside diameter that is substantially the same as the inside diameter of the opening. The interior is adapted to accept and surround the threaded end. The thread protector may be actuated between a locked and an unlocked configuration. When the thread protector is in the locked configuration, a portion of the inside diameter is reduced, as compared to when the thread protector is in the unlocked configuration, so as to securely mount the thread protector to the threaded end.

Abstract: This tubular member thread protector generally comprises an outer member capable of rotation in a first direction about an axis and an inner member coaxially integrated within the first member and capable of rotation in an opposite direction. The inner member comprises a flexible annular sleeve having an outer surface and an interior surface defining an interior annular space capable of receiving the tubular threaded end. One or more camming surfaces are disposed about the inner sleeve outer surface. The outer member comprises a generally annular structure having a closed end, an open end, an outer surface and an inner surface. One or more raised camming members are disposed about the outer member inner surface and are aligned with sleeve camming members during rotation, the outer member camming members press against the inner sleeve camming members to radially compress the sleeve inner surface against the threaded member.

Abstract: A method of manufacturing a sabot projectile is disclosed in which the projectile core is used as the core pin of a mold and a sabot is molded directly onto and in alignment with the projectile core and the core nose is held by a special alignment ring.
