| 20100233651 | Electric Motor For Use in a Dentist's, Dental Surgeon's or Dental Technician's Hand Piece - In an electric motor for use in a handpiece for dentistry, dental medicine or dental technology, with a rotor held rotatably by a bearing arrangement, and a stator surrounding the rotor, a bearing arrangement has a first bearing located on an end region of the rotor, and a second bearing located on an opposite end region of the rotor, which second bearing is constructed as a movable bearing and is biased in the direction of the first bearing by a spring arrangement. The spring force of the spring arrangement within an operating region is substantially independent of the position of the movable bearing. | 09-16-2010 |
| 20100209872 | ROTOR FOR AN ELECTRIC MOTOR, ELECTRIC MOTOR AND DENTISTRY HANDPIECE - The rotor for an electric motor used with a dental handpiece has a shaft with a rotational axis and a magnet arranged around the rotational axis. A centering element may be rigidly connected to the shaft or constructed as part of the shaft. The centering element presses on the magnet from the outside to center it in relation to the rotational axis of the shaft. The centering element may be pressed or shrunk on to two balancing rings. The balancing rings can be pressed or shrunk on the shaft. This allows precise centering of the magnet with respect to the rotational axis of the shaft to be achieved. The pressure exerted by the centering element on the magnet counteracts centrifugal forces during rotor rotation. Particularly high speeds may be achieved without the surface of the magnet exceeding a critical tensile stress. | 08-19-2010 |
| 20100151415 | Device for Further Processing a Fluid Materials - A device for further processing a fluid material, particularly a care device for medical or dental tool holders, the material being stored in a tank under pressure, the device having a coupling fixture having an adapter forming a screw connection to the tank under pressure, the adapter of the coupling fixture being pivotally supported. | 06-17-2010 |
| 20090068618 | METHOD AND DEVICE FOR DETERMINING THE CENTRIC POSITION OF HUMAN TEETH - The invention concerns methods and a device for the determination of the centric position of a human set of teeth with improved precision. This is needed for the adjustment of an articulator in the production of dentures. For this purpose a plurality of successive bite movements or displacement movements of the lower jaw are recorded in form of electronic signal data and evaluated for the determination of the centric position. | 03-12-2009 |
| 20090004622 | Dental, Dental-Medical or Dental-Technical Handpiece With Electric Motor - In a dental, dental-medical or dental-technical handpiece, having an elongate grip sleeve there are provided at the rearward end of the grip sleeve coupling elements for the connection of the handpiece to a supply hose to be connected with a dental supply arrangement, and there are provided at the forward end of the grip sleeve a head section with a tool receiver for mounting a tool to be put into rotation. The handpiece further has an electric motor for driving a tool held by the tool receiver, which motor is completely integrated into the grip sleeve such that grip sleeve and motor form a unit. | 01-01-2009 |
