Abstract: A shoe comprising a sole. The sole includes a forward outsole and a heel outsole. The forward outsole and heel outsole each include respective primary and secondary ground engaging members. Each primary ground engaging member defines a hole therein, and the corresponding secondary ground engaging member is positioned within the hole. In addition, each primary ground engaging member and corresponding secondary ground engaging member are adapted and configured so that respective bottom surfaces of each can simultaneously contact a flat ground surface when the shoe is worn. The sole has a rearward through hole within a heel region and a forward through hole in a toe region and a metatarsal region. A heel cushion extends through the rearward through hole and is positioned at least partially within the heel outsole and at least partially above the heel secondary ground engaging member.

Abstract: A system and method of constructing multi-story buildings having poured-in-place concrete floors for the upper floors, wherein a set of lower posts is erected, the lower posts having horizontal upper plates on their upper ends each with a centrally disposed aperture. Decking is supported by horizontal beams and defines a form to receive the concrete. The upper plates are masked and concrete is poured and screeded using the upper plates as screed guides, such that the upper surface of the concrete is generally flush with the upper surface of the upper plates. After removal of the masking, a set of upper posts having lower plates with centrally disposed pins are mounted atop the lower posts with the pins inserted into the apertures. The lower plates and upper plates are then welded to joint the lower and upper posts. The cycle is repeated for additional floors.

Abstract: A demolition derby game wherein vehicles are positioned on a gameboard and driven by means of manually operated magnetic manipulators positioned beneath the gameboard. There are plural such vehicles, one vehicle operated by each player. Each vehicle includes a plurality of identical removable elements, such removable elements being removable upon impact with another vehicle. The removable elements fit into grooves in the vehicle and are positioned about opposite sides of shafts with spring elements and disc portions at their ends. The impact of a vehicle with another vehicle will cause a shaft to move and force one of the removable elements out of its groove and onto the playing surface.
