Abstract: Gaming systems and methods for providing a customer with additional non-cashable credits upon completion of the game are provided herein. The gaming machine includes a game controller that is configured to receive a player input to play a wagering game on the gaming machine. The game controller is also configured to generate results for the wagering game, wherein the results include credits won or lost. The game controller is configured to add or subtract the credits won or lost to the player's total credit balance and provide the player with an amount of additional non-cashable credits upon ending the game, wherein the player must forgo a portion of their remaining credits in order to receive the amount of additional non-cashable credits, and wherein the non-cashable credits cannot be used with the same or another gaming machine without an additional input of currency into the gaming machine by the player.

Abstract: A railroad friction-modification system for applying a friction modifier to a section of railroad track, the system comprising an external storage tank for storing the friction modifier, a railroad friction-modification assembly for applying the friction modifier, a tube for connecting the external storage tank to the railroad friction-modification assembly, and a mounting assembly for securing the railroad friction-modification assembly to the rail. The railroad friction-modification assembly includes an expandable membrane for storing the friction modifier, an inlet valve for receiving the friction modifier from the external storage tank, a housing for securely containing the expandable membrane, at least one outlet valve for expelling the friction modifier from the expandable membrane upon the application of a force, and a nozzle for directing the expelled friction modifier onto the section of railroad track.

Abstract: A combination coin and key holder includes a coin holder housing which has an outline shaped as a vehicle. A closed loop is attached to the coin holder housing, preferably in the front end of the vehicle outline, for connection of a key ring, chain, or other key holding device thereto. A pair of coin slots are provided in the coin holder housing on the bottom side of the vehicle outline, with each slot being dimensioned to hold a specific coin. The coin slots are positioned and configured such that coins inserted thereon are reliably, yet removably retained in place, but such that they protrude sufficiently to have the appearance of a wheel or wheels on the vehicle outline.
