A device for receiving an ingredient cartridge and extracting the ingredient by passing heated liquid through the cartridge, comprises: a cartridge seat that has an open configuration for receiving andor removing a cartridge from such device and a closed configuration for extracting the ingredient; and a force generation means for assisting a closure or opening movement of the cartridge seat. Novel crystals of compound homogeneous and excellent in the stability characterized by exhibiting the diffraction angles at at least 17. An electrode on the lower contact surface may be in the form of a ring substantially encircling the mesa. The system retrieves the printing and finishing parameters and formats PDL and JCL commands which can be forwarded onto the printing and finishing system. Repeating means for these mobile devices to extend the range of coverage and the protocol for that coverage.
