20090084761	Multi-Vacuum Contactor Control System - A control system for controlling and synchronizing a plurality of medium-voltage vacuum contactors comprises a two-level network structure. A dedicated network includes a plurality of servant control units operably coupled to the vacuum contactors and configured to ascertain a plurality of different data and conditions thereof. In addition, the dedicated network includes a master control unit in serial communication with the servant control units and configured to send and receive communications therewith. The master control unit is operably coupled to a control network including a plurality of various control devices. The master control unit is configured to send predetermined data received from the servant control units to the control network. The two-level network structure enables relatively jitter free communication on the dedicated network while not overwhelming the control network with unnecessary data. The system is further configured to diagnose and prevent a variety of different vacuum contactor failures.	04-02-2009

20100323338	APPARATUS FOR DIDACTIC DENTISTRY OPERATIONS - An apparatus for didactic dentistry operations comprising a base structure conformed so as to define a supporting plane raised from the floor, and a dentistry simulation apparatus pivoted to the supporting plane, so as to be able to rotate with respect to the latter between a first operating position, in which the simulation apparatus extends laterally from the bulk of the supporting plane, and a second inactive position in which the simulation apparatus is substantially comprised in the bulk of the supporting plane. The simulation apparatus is pivoted to the supporting plane in correspondence with a median zone of the latter. The supporting plane comprises a housing seating which at least partly accommodates the simulation apparatus in the inactive position thereof.	12-23-2010
