Abstract: Techniques are dis closed for facilitating configuration of a gaming machine, and for facilitating authentication testing of selected components of a gaming machine. In at least one embodiment, configuration of the gaming machine may be effected via the use of a gaming machine configuration device. When the presence of a gaming machine configuration device is detected, configuration indicia stored on the configuration device may be accessed and used to determine at least one configuration parameter relating to configuration of the gaming machine. Configuration or reconfiguration of the gaming machine may then be implemented using the at least one configuration parameter. In at least one embodiment, authentication of the gaming machine component may be effected via the use of a gaming machine authentication device.

Abstract: A fermentation tank for use in the agricultural and food industry sector, and particularly for viticulture is provided at its bottom with a side opening (4) that communicates with a box (3) that permits the introduction of the arm (13) of a mobile extractor. The arm (13) carries a rotary blade (23) that gathers solid deposits and to discharge them through an opening (12). During the fermentation process, the box (3) is covered with a removable grid (10) that prevents solid deposits entering the box. An opening (7) at the box base (3) provides for the discharge of liquids.
