Abstract:

A variable compression ratio mechanism for continuously varying the compression ratio of an internal combustion engine while minimizing the power requirement and providing internal clamping to isolate the setting mechanism from the reaction to combustion loads. The mechanism includes a setting cam () actuated via an innovative torque storage system acting on an auxiliary piston () in the combustion chamber crown. The mechanism provides very fast and precise transient response without the use of hydraulic control. The invention desirably simplifies the control system and provides an elegant and compact solution for this purpose.

Abstract:

A golf putter club having a stationary grip portion hingedly mounted to a swingable shaft portion. A head mounted at its center of gravity to the remote end of the shaft. An alignment mark visible to the user engraved on the top surface of the head perpendicular to the face of the head. A sighting device is mounted on the stationary grip whereby, upon placing the face next to the ball, the user may align a preselected target with said alignment mark assuring the face to be perpendicular to the target. While holding the stationary portion, thereby keeping the face aligned, the user may move the swingable shaft portion to impart a pendulum action force to the ball to drive the ball toward the target.
