Abstract: Described herein is a golf club head comprising a composite material, the golf club head further comprising: a front end having a bottom rail, a top rail, and a strikeface, the strikeface including a striking surface, a back surface, and a reinforcement element extending from the back surface of the strikeface; a rear end opposite the front end; a heel portion; a toe portion opposite the heel portion; a sole coupled to the front end along the bottom rail at a sole transition region, the sole extending toward the rear end of the golf club head and including a sole thickness, a first weight member and a second weight member, and a perimeter wall extending from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head, wherein the perimeter wall decreases in height from the front end toward the rear end of the golf club head.

Abstract: A serial element of a load lifting line has a telescoping body held in a short configuration by a linear slip clutch until a selected load on the line is exceeded. The slip clutch then allows the body to extend to a longer configuration in which it is retained as a length unit by abutting surfaces between which an elastomeric shock cushion is positioned. An optional arrangement includes a biasing provision to restore the link to the original condition, for further use, after the load is reduced. By utilizing optional provisions, the link can signal the overload condition by a whistle when the telescoping body extends. Visible signals can, optionally, be provided by members that extend from the body when the body is telescoped to the longer condition.

Abstract: A safety fuse link, usable as a serial element of a load lifting line, has a telescoping body held in a short configuration by a linear slip clutch or a shear pin until a selected load on the line is exceeded. The body then extends to a longer configuration in which it is retained as a length unit by abutting surfaces between which an blastomeric shock cushion is positioned. An optional arrangement includes a biasing arrangement to restore the link to the original condition for further use, after the load is reduced.
