A thulium doped silicate glass composition which contains SiO2, Al2O3, and La2O3 emits visible and UV light when excited by infrared light. The first party accepts payment via a plurality of different payment options selectable by the second party, and the plurality of different payment options are associated with a plurality of different authentication protocols prescribed therefor. After a predefined period of time elapses, the ash transport system transports the ash mass from the airlock or hopper valve to the transport line if the pressure in the transport line falls below different respective predefined pressure thresholds. The fitting can be used within any air, other gas or liquid flow system. The moving unit moves the recovery unit to a position where the recovery unit faces the ink jet head and to a position where the recovery unit does not face the ink jet head, the ejection forming surface of which is oriented toward the printing medium.
