| 20120231410 | DEVICE FOR DISPENSING A DENTAL MATERIAL - A device for dispensing a dental material comprises a plunger for extruding a component of the dental material, and a motor for driving the plunger. The device has two electric circuits for powering the motor to drive the plunger forward or backward. A selector switch is arranged in the device for alternately selecting between the first electric circuit and the second electric circuit for powering the motor. The device further has switches for interrupting the first and/or second electric circuits when the plunger is positioned at certain positions. The device provides automatic functionality for facilitating dispensing of dental materials, and further is preferably relatively robust and relatively inexpensive to manufacture. | 09-13-2012 |
| 20120292341 | DEVICE FOR DISPENSING A DENTAL COMPOSITION - A device for dispensing a dental composition comprises a piston for extruding a component of the dental composition from a container. The device has a roller drive for displacing the first piston. The roller drive comprises cooperating first and second rollers, and each of the rollers have a roller surface with a radial rib profile. The rollers are arranged for rolling with their roller surfaces on one another. The invention may help providing for a relatively reliable and compact device. | 11-22-2012 |
