摘要:
A needleless hypodermic injection system for injecting a liquid medication, which system comprises a disposable cartridge which contains a medication and which includes a propellant and an igniter, and a reusable application device which comprises a pressure chamber for receiving the medication cartridge, actuation means including an ignition system and means for ensuring reliability and safety of the system. The reusable application device comprises: (a) a housing including a fist housing section and a second housing section which are adapted to be assembled together by a screwing operation, the first housing section comprising a front part having an injection outlet and a chamber adapted to receive a the cartridge contains the medication to be injected and also contains a propellant and an igniter, and (b) means for selectively activating said igniter of said cartridge when predetermined conditions are fulfilled.

The invention relates to a grinding-spindle assembly comprising a fixed shaft and a ring motor that has a stator and a rotor, wherein the stator is connected in a fixed fashion to the shaft, the rotor is a hollow shaft and is pivotal on the fixed shaft, and the grinding tool is connected in a rotationally fixed fashion to the rotor, and the ring motor extends through the grinding tool. The fact that the grinding tool is mounted directly on the rotor produces an especially space-saving construction.

The invention relates to a tool for the mechanical processing of workpieces, in particular for the joining, self-piercing riveting or clinching of sheet, tube or profile parts, having tool-insert carriers which are movable relative to one another and to the working ends of which a respective tool insert of a tool set can be fastened, and having an electric-motor drive which acts on a plunger of at least one tool-insert carrier for performing a working stroke, the drive comprising as drive member a cam disk (21) which can be driven by a shaft (32) of a motor (31) and controls a positive motion of a stroke member which is formed by a rocker (16) which is pivotably mounted about a fixed axis (16.1) perpendicularly to a working stroke direction of the movable tool-insert carrier (1, 2) and whose free end (17) moves a plunger (9) guided in the working stroke direction.
