  • Patent number: 10300931
    Abstract: A railroad well car includes a spaced trucks grouped in pairs, and a railcar body supported on a pair of the trucks, the body comprising a pair of spaced end structures, each end structure supported on one truck, and a well structure extending between the end structures. The well structure comprises a pair of top chord members extending between the end structures; a pair of side sills extending between the end structures. The rail car includes safety platform and handbrake wherein operator walkway platforms are included with co-planer end walkways and running boards, wherein the running boards are above the top chords of the sidewalls of the well car; and a handbrake operated with a hand wheel is mounted on one side of the railroad well car, which hand wheel extends below the top chords of the side walls of the well car whereby the hand wheel is accessible from the side of the railcar via an operator on the ground.

  • Patent number: 7521947
    Abstract: A test system, apparatus and method for applying high current test stimuli to a semiconductor device in wafer or chip form includes a plurality of probes for electrically coupling to respective contact points on the semiconductor device, a plurality of current limiters electrically coupled to respective ones of the plurality of probes, and a current sensor electrically coupled to the plurality of probes. The current limiters are operative to limit current flow passing through a respective probe, and the current sensor is operative to provide a signal when detected current in any contact of the plurality of probes exceeds a threshold level.
