A hollow golf club head with a concave portion is disclosed and claimed. The club head includes a metallic portion and a light-weight portion, which may be formed of plastic, composite, or the like. The concave portion allows the club designer to make a club head having very thin portions while still maintaining the requisite structural integrity. Convex bulges may optionally be provided to house weight inserts to enhance the playing characteristics of the golf club. The metallic portion of the club head may take on the appearance of a frame, into which several light-weight inserts are positioned. These light-weight inserts may be positioned in the crown, skirt, and sole of the club head. The club head may be formed by co-molding, eliminating the need for welding or adhesives, freeing mass to be used in more beneficial ways. The club head may be large to increase playability and forgiveness. The club head may include one or more light-weight inserts to manipulate the playing characteristics of the resulting golf club. These inserts may have attachment surfaces that are relatively angled such that the inserts are subjected to compressive forces rather than shear forces upon impact with a golf ball during a golf swing.

An erosion sensor provides a signal which varies in dependence upon an electrical resistance of the sample layer, which is related to the erosion of the sample layer. An apparatus also monitors a substantially longitudinal production flow through downhole production tubing in an oil or gas well. A method and apparatus are used to monitor the condition of a gravel pack within an oil or gas well. Other methods monitor temperature or pressure conditions within an oil or gas well.

A high velocity munition comprises a projectile, mounted on a cartridge case, that can be fired from an automatic cannon or weapon. During storage or transport an IM venting device included in the cartridge case prevents the propellant charge from firing the projectile, leaving the cartridge damaged, but intact upon premature ignition.

At least one non-fusible, ruptureable member is included in the IM vent channel and positioned to provide structural integrity to the fusible material in the channel. Alternatively or in addition to the fusible material, a shape memory alloy ring surrounds the igniter (or primer) and separates from the cartridge when the cartridge reaches a temperature that causes auto-ignition.
