Title: Apparatus and method for thermal de-burring of slotted well liners
Inventor: CLAERHOUT MIKE
IPC: B23D79/00
Filed: 2004-04-22
Granted: 2007-10-02
Abstract: A method and apparatus for removing burrs from inside slotted metal liners exposes the burrs to a high-intensity gas flame that effectively oxidizes or incinerates the burrs, without inducing undesirable temperature levels in the parent metal of the slotted liner. This is accomplished using a torch head assembly having multiple gas torch nozzles disposed radially around the circumferential perimeter of the torch head, such that when the torch head is passed through the interior of a slotted liner, the flames are directed toward the interior surface of the liner. Auxiliary oxygen is introduced at the nozzle outlets, resulting in a large increase in flame velocity and intensity and, in turn, an increase in the flame temperature. The auxiliary oxygen may be introduced through annular passages surrounding the nozzles, such that the auxiliary oxygen effectively forms a cylindrical curtain surrounding the flame at each nozzle.

Title: Security for gaming devices
Inventor: FALVEY GRAHAME M
IPC: G07F17/32
Filed: 2006-01-23
Granted: 2013-10-01
Abstract: A secure smart card or other secure modular memory device is plugged into (or otherwise connected to) a port of a game controller board internal to a gaming machine. The smart card is programmed to detect an encrypted "challenge" message from the host CPU and output an encrypted "response". If the host CPU determines that the response has the expected properties, then the host CPU verifies that the game program is authentic (i.e., the game program is accurate and authorized for use by that particular gaming machine and customer), and the game can be played. The challenge/request exchange may be performed before every game is played on the machine or at any other time. If the response is improper, then the host CPU will issue a halt command to halt play of the game. By controlling access to the properly programmed smart card, gaming machines cannot run unauthorized copies of the game program. Various other security features are disclosed for protecting communications and data within the gaming machine, such as erasing secure memories if tampering is detected and requiring that an authorized secure smart card be connected to each one of multiple game boards in a single gaming machine for accurate secure communications between boards.
