VERBUNDGARNPRODUKT UND VERFAHREN ZU SEINER HERSTELLUNG
VERFAHREN ZUR BIOLOGISCHEN REINIGUNG VON ABWASSER
Processing of waste material contg. vanadium, titanium, chromium, etc. - by incorporating into brick making material to give colour effect
Rechargeable accumulator, esp. for impulse operation - giving high energy discharge, with neutral perchlorate electrolyte
Temp. conditioning system for testing vehicle engines - having closed circuit air system with temp. control, to create an air stream of controlled temp., around the test piece (OE 15.1.79)
BILDAUFZEICHNUNGSMATERIAL
Torsional moment anchor coupling system - has outside stress system with tension and pressure elements for force introduction
Feeding system for individually-held animals - has feed conveyor operated by animal with number of tap and delivery points
Electroerosion spark machine control - with pulse generator for constant pulse amplitudes in operation and short circuits
Instant picture camera with flash synchronisation - has cassette-operated switch preventing operation if light-proof cover has not been removed
Magnetic tape recorder cassette - has movable plate extending to about middle of cassette, and cassette ejection device
Synthetic filament yarn crimping process - incorporates a stabilising zone so that all stages can be structured independently
