Abstract: A column segment comprising a body having at least one external channel, an upper protrusion extending from a top side of the body, and a lower protrusion extending from a bottom side of the body, wherein the at least one external channel further comprises an outer angled wall arranged to receive a securing means and direct said securing means through the at least one external channel, wherein the upper protrusion includes a domed portion and a plurality of locating slots, wherein the lower protrusion includes a domed recess and a plurality of projections, and wherein a first column segment is stackable with a second column segment by the domed portion and the locating slots of the first column segment matingly engaging with the domed recess and the projections of the second column segment.

Abstract: A game having a floor, a plurality of walls rising up from said floor defining a play area, a game piece, at least one target positioned proximate the plurality of walls, including a plurality of multi-planar apertures operatively arranged to accept the game piece, and a vehicle, operatively arranged to be driven by a player, the vehicle having a bumper positioned circumferentially about a base of the vehicle.

Abstract: Apparatus for sequencing the release of a missile from its launch apparatus, the unlocking of the missile's warhead fuze pre-launch safety lock, and the ignition of the missile's rocket motor. A cylindrical block having a radial passageway is situated between the warhead and the rocket motor of a missile. An actuator piston having a hollow cylindrical core slides within the passageway. One end of the actuator piston projects from the passageway and is engaged with the launch apparatus to prevent movement of the missile relative to the launch apparatus prior to launch. A source of pressurized gas communicates with the hollow core of the actuator piston through an opening in the actuator piston's projecting end. A notch in the side of the actuator piston is engaged with the warhead fuze pre-launch safety lock.
