    摘要: Burner tubes for coke oven heating flues and method and apparatus for inserting and/or removing the same from burner nozzles. The burner tubes themselves can be inserted or removed from burner nozzles permanently installed in the sole of a heating flue and comprise thin-walled alumina elements provided with external fins adapted to engage the top edges of the burner nozzles. The apparatus for inserting and removing the tubes comprises two pivotally-connected rods, the lower of which is adapted to carry either a fixture which can insert a burner tube into a burner nozzle or a fixture which can remove a burner tube. In either case, the fixture is such that it can be engaged with, or disengaged from, a burner tube by manipulation of the uppermost pivotally-connected rod without manual contact with the tube in the heating flue itself.

    摘要: A process and an apparatus that can be used for surface preparation and treatment of a metal workpiece surface, for example in a processing stage prior to adhesive assembly, without using environmentally harmful materials. The process comprises triggering and maintaining pulsed unipolar arc discharges between an electrode wired as an anode and a workpiece surface wired as a cathode, with the arc discharges following one another with a timing, number, and speed such that they do not cause macroscopic melting of the workpiece surface while ensuring complete extinction of the individual arc discharges. The apparatus comprises an electrode as the anode and the workpiece as the cathode, and a generator or component for generating electrical pulses.
