Abstract: The present invention provides a method of playing a card game comprising the steps of providing a dealer, providing at least one player, providing a playing surface that displays a plurality of cards having graphical elements, the at least one player selecting at least one player card on said playing surface, the dealer identifying at least one dealer card having graphical elements, and determining whether the graphical elements on said player card match the graphical elements on said dealer card.

Abstract: An overhead rotatably powered conveyer drive shaft has ridges inter-engaged with skewed driven wheels mounted for free rotation on a load carrying carriage to trace a helical loci of engagement and improve traction. The ridges are preferably extruded to be parallel. The driven wheels may also have extruded parallel ridges or have an elastic peripheral surface deformed elastically into spaces between adjacent drive shaft ridges during normal conveying to provide the inter-engaging.

Abstract: A chain drive overhead conveyer extends through an oven to move carriages between exit and entrance ends of respective rotary drive shafts that are outside the oven. Driven wheels of the carriages are canted with respect to the rotary drive shafts so that when a drive shaft is rotated, a helical loci of engagement between the drive shaft and engaged driven wheels provides sufficient traction to propel the carriages along the conveying path outside the oven. Weight of loaded carriages is carried through carriage support wheels to a load support structure adjacent to and independently of the rotary drive shafts and the chain conveyer through the conveying path. Heat sensitive portions of the carriages, e.g. the driven wheels, are chilled at the exit of the oven.
