Abstract: The invention concerns a process for the aligning of the tooth spaces of workpieces (1) with precut teeth, which are set up for fine machining on the work spindle (2) of a gear finishing machine. In order to avoid the trend related occurrence of out-of-tolerance aligning errors as series production progresses, teach-in cycles are performed on the workpiece machined in the immediately preceding machining cycle, called for automatically after time intervals or machining cycle intervals which are either pre-defined or calculated by the machine control system. By this means any prevailing trend errors are restored to zero.

Abstract: An apparatus for filling a cartridge with a liquid comprises, a platform on which the cartridge is supported and which can be lifted relative to a stationary filling needle (5) so that this filling needle is moved into the cartridge (6), a pump (1) feeding liquid through the filling needle (5) into the cartridge (6), a sensor head (10) from which a beam of light is sent from one side of the cartridge to the other along a path immediately over an upper edge of the cartridge (6), and a reflector (11) reflecting the light beam back to the sensor head (10), which is connected to a sensor box (12) which produces a signal stopping the pump (1) and causing the needle (5) to be drawn out of the cartridge (6) when this cartridge is full and the liquid forms a droplet over the opening of the cartridge, which droplet deflects the light beam.
