A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

An improved mechanism for retaining screws for a conduit body cover is disclosed. The screws are retained by a layer of PVC lining the inner surface of holes in the cover.

The invention relates to a process for producing a composite component having at least one functional element composed of at least one cylindrical hollow profile and at least one plastic to be introduced into the hollow profile by means of specific injection molding methods.

An apparatus is configured to be positioned between a boss and a shell of a pressure vessel. The boss includes a bore therethrough, and the bore has a longitudinal axis. The apparatus includes an annular body and a gas permeable feature. The annular body includes an inner surface configured to abut the boss and an outer surface configured to abut the shell. The annular body has opposite first and second ends relative to the longitudinal axis. The gas permeable feature is provided on the inner surface and extends at least from the first end to the second end. The disclosure also describes a pressure vessel including a shell, and boss, and an apparatus positioned between the boss and the shell. A method for forming a pressure vessel includes mounting a boss on a mandrel, positioning an annular fitting about a neck of the boss, forming a liner, and forming an outer shell.

A metal component has a shape including a flat plate-shaped part, and the flat plate-shaped part has a through-hole formed therein. A resin component has a shape including a covering part that covers a surface of the flat plate-shaped part, and the covering part has a surface in which a gate mark is present. The through-hole formed in the flat plate-shaped part of the metal component is located opposite to the gate mark. The resin component has a filler part with which the through-hole is filled.

An improved golf club head is provided having a striking face portion, a topline, a heel portion adapted to receive a shaft, a toe portion, and a sole. The improved golf club head includes port holes extending from one or more cavities to allow insertion of a polymer and metal shot into the golf club head. The insertion of a polymer and metal shot facilitates increasing weight and/or biasing weight distribution of the golf club head. The improved golf club head may be manufactured by forging the main body of the golf club head, machining a recess into the main body, and attaching an insert in the recess. The recess forms a cavity and allows a port hole to facilitate insertion of the polymer and metal shot into the golf club head. After insertion, the polymer is cured to form the golf club head.

Apparatus and method of forming connector brackets for irrigation laterals along a prefabricated lay-flat pipe and lay-flat pipe with such connector's brackets, wherein an opening is formed at one wall of the premanufactured pipe, a separation means is positioned inside the pipe opposite the opening while separating the one wall from the second wall of the pipe, and an injunction molding is performed into a mold cavity, in order to form the bracket affixed to the one wall of the prefabricated pipe and around the opening.

A cushioned article includes a cage and a compressible material. The cage has at least one opening, an interior volume, and an outer surface. The at least one opening provides a passage from the outer surface to the interior volume. The compressible material extends through the at least one opening in the cage. A method for manufacturing a cushioned article includes providing a mold having at least one cavity, placing a cage within the mold, and injecting a compressible material into an interior of the cage. The cage includes at least one opening. A portion of the compressible material flows through the at least one opening in the cage and fills the at least one cavity of the mold. One or more shields may be connected to the cage before injection. The shields may be removed with the cage and heat treated with the shields still connected to the cage.
