Abstract: A gaming machine including a secondary processor coupled to a player tracking system for tracking game play of a patron using a virtual player loyalty card is described. A virtual player loyalty card can be created by associating an existing physical player loyalty card with a newly created mobile loyalty card account. The mobile card can be virtually inserted into an electronic gaming machine when a portable electronic device with an associated mobile application is in the vicinity of an electronic gaming machine. Once the mobile card is virtually inserted into the gaming machine, the patron's game play at the gaming machine can be tracked.

Abstract: An empty and load air brake control apparatus for railroad freight cars, for applying full braking forces to the car wheels when the car is riding loaded, but for applying reduced braking forces to the car wheels that are at appropriate force levels when the car rides empty, in which in addition to the conventional brake pipe, AB or ABD control valve, the auxiliary and emergency reservors, the brake cylinder, and the retaining valve, are included a special load sensing device and a modulating valve for supplying full braking air pressures to the brake cylinder when the car rides loaded and reduced braking air pressures to the brake cylinder when the car rides empty.

Abstract: A modulating valve for railroad car brake cylinders to adapt them for operation with composition brake shoes, in the form of an assembly comprising a bracket plate arranged for connection in the brake cylinder pipe, at a convenient location between the brake cylinder and the AB control valve, in place of a portion of the brake cylinder pipe removed for that purpose, and a modulating valve mounted on the bracket plate and in communication with the brake cylinder pipe and brake cylinder to limit the fluid pressures supplied to the brake cylinder so that composition brake shoes will deliver the proper brake applying force to the truck wheels without interferring with proper operation of existing brake control equipment.

Abstract: A modulating valve for railroad car brake cylinders to adapt them for operation with composition brake shoes, in the form of an assembly comprising a bracket plate shaped for mounting between the brake cylinder pipe flange type fitting that connects the brake cylinder pipe to the brake cylinder and the cylinder head, and that is arranged for a three point securement to the cylinder head, and a modulating valve mounted on the bracket plate and in communication with the brake cylinder pipe and brake cylinder to limit the fluid pressures supplied to the brake cylinder so that composition brake shoes will deliver the proper brake applying force to the truck wheels without interferring with proper operation of existing brake control equipment.
