| 20110195375 | INTERNAL BROACHING TOOL - An internal broaching tool for broaching profiles delimited by a root and flanks in one aspect arranges a relief part between the toothed part and the calibration part. The calibrating broaching teeth in adjacent rows on the calibration part have a guiding flank (without a clearance angle or with a maximum negative clearance angle of 0.1°) and a cutting flank (with a positive clearance angle). The guiding flanks and the cutting flanks on the calibrating broaching teeth located behind each other in the direction opposite the broaching direction are alternately offset relative to each other in adjacent rows. The position, shape, and size of each guiding flank located downstream in relation to the direction opposite the broaching direction are associated with the position, shape, and size of the associated cutting flank (or the flank of the broaching tooth) in the preceding row. | 08-11-2011 |

| 20080221602 | Appliance for Water-Jet Surgery - An appliance for water-jet surgery is provided that includes a plurality of supply cylinder and piston arrangements in each of which is stored a working fluid that can be expelled, by means of the piston, through an outlet into a pressure conduit. At least one actuation device is provided to actuate the piston of each supply cylinder. By means of a change-over device to change the actuation from the piston of one supply cylinder to the piston of another supply cylinder, it is ensured that the working fluid can be expelled into the pressure conduit from consecutively emptying supply cylinders. As a result, an apparatus with a small structure that is achieved by simple means is disclosed. | 09-11-2008 |
| 20090060764 | Medical Pump - Medical pumps for water jet surgery are known. The invention relates to a pump comprising at least two pistons provided with piston rods for displacing the pistons in cylinders and for coupling to a pump actuation device, a cylinder head for closing the cylinders, and valve means for respectively connecting a pressure chamber in the cylinder to at least one fluid inlet and at least one fluid outlet. Said fluid outlet is connected to the fluid inlet in a communicating manner by means of an adjustable pressure regulating valve, in such a way that the pressure in the fluid outlet can be limited to a predetermined maximum value so that operation of the pump can be. | 03-05-2009 |
