Abstract: A drill bit has a plurality of cutters secured to the bit body, including a gauge cutter defining a gauge diameter of the drill bit. A reciprocating gauge assembly on the bit comprises a cavity defined in the bit body, a piston reciprocably disposed in the cavity, a wear element on an outwardly facing end of the piston, a piston retainer for moveably retaining the piston in the cavity, and a spring biasing the piston outwardly to a neutral position of the wear element with respect to the gauge diameter. The wear element and piston may be urged inwardly in response to an applied load at the drill bit gauge pad, increasing the lateral depth of cut and thereby controlling the aggressiveness of the bit in response to the load.

Abstract: Gaming machines having video depictions of one or more mechanical reels projected onto a curved display are disclosed herein. In one embodiment, the gaming machine includes a curved transparent material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel. The gaming machine also includes a light emitting diode projector for projecting video images of one or more reels onto the inner surface of the curved transparent material. The gaming machine also includes a light piping material positioned in front of the curved transparent material for illumination of the display. The gaming machine further includes light piping material placed in front of speakers associated with the gaming machine for illumination of the speakers. The illumination of the display or speakers may be synchronized with sound.
