Abstract: Provided herein are methods for solid state quenching of metal including transferring a heated metal workpiece having an initial workpiece temperature to a press, the press including a first die having an initial first die temperature, the initial first die temperature being lower than the initial workpiece temperature and a second die positioned opposite the first die and having an initial second die temperature, the initial second die temperature being lower than the initial workpiece temperature, wherein the first and second dies are each constructed of a material having a thermal conductivity equal to or greater than 90 W/mK at a temperature of 70 F, closing the press to bring the first die and the second die into pressurized contact with the heated metal workpiece, continuing the pressurized contact between the first and second dies and the metal workpiece to cool the metal workpiece from the initial workpiece temperature to a quenched workpiece temperature, opening the press when the metal workpiece rea

Abstract: Multivenue jackpot system comprising a central control system (6), connecting via a communications network (4) to a jackpot controller (32) at multiple gaming venues (26). Each gaming venue (26) having multiple electronic gaming machines (28) (i.e. poker, slot, video machines which include hard meters and a jackpot interface (56) for linking via a venue network (30) to the jackpot controller (32). The gaming machines (28) are capable of playing independent games and participating in a multiple gaming machine jackpot game. The central control system (6) increments on the basis of the hard meter signals and/or awards a jackpot sum from a jackpot pool to a selected gaming machine (28). The jackpot interface (56) is a separate circuit board capable of being fitted to a standard gaming machine (28). Jackpot award criteria include random time, predetermined levels, usage factor of gaming machine (28) and gaming venues (26).
