Abstract: A heavy duty, high efficiency jumper cable system designed to deliver 250 to 3,800 amps with minimal loss by transmitting current from a source through a cable/terminal connector through a heavy duty cable to a second cable/terminal connector and then to a discharge point. The cable/terminal connectors include an electrical harness that minimizes power loss by direct contact between the cable delivering current to the cable connector and a pair of electric contacts, each member of which is positioned in an end of a support. The system is uniquely, but not specifically adapted for use with electrical systems associated with diesel powered vehicles and equipment.

Abstract: An athletic shoe sole comprising a midsole and an outsole. The midsole has a longitudinally concave shaped ball portion which is thinnest along a transverse metatarsal line, such that a longitudinal concavity is formed facing downwardly and crossing the entire width of the ball portion of the midsole. The outsole has a longitudinally convex shaped ball portion which is thickest along the transverse metatarsal line, such that a longitudinal convexity is formed facing upwardly and crossing the entire width of the ball portion of the outsole. The longitudinally convex shaped ball portion of the outsole has numerous conical shaped hollow tread members aligned in a plurality of transverse rows, and two longitudinally elongated edgewise non-hollow tread members each having a plurality of transverse grooves.
