Abstract: A wedge clamp is provided. The wedge clamp includes wedge members aligned with a shaft and in sliding contact with surfaces of the neighboring wedge members. Some of wedge members each include a finger and a void, with the finger of a first member slidably inserted within the void of a second wedge member and vice versa. The fingers and voids extend at an acute angle, and the fingers and voids of other wedge members extend at another acute angle on an opposite side of a vertical axis. When the shaft is rotated some wedge members vertically translate with respect to the remaining wedge members. When the shaft is rotated in the reverse direction the wedge members translate vertically in the opposite direction returning to an original position. The interaction of the fingers and voids mechanically drive the moved wedge members into the original state.

Abstract: A partition for adjusting noise emanating from the engine compartment of a vehicle. The partition is provided for installation over the engine compartment of a vehicle and may comprise an opening integrally formed therein, a conduit communicating with the orifice, and a movable panel, the movable panel being operatively connected with the conduit. The panel can be moved manually or by mechanical or electrical remote actuation. The partition can be light transmissive, and a light source can be disposed proximate to the partition for illuminating the engine compartment.
