Definitions

  • the vvorkpieces are arranged 1n 134/105, 134/135, 134/143, 156/345 a removable contalner swmglngly rnounted on the 51 1111.01 B08b 3/08 the bath aPPaaFUS- P' avmds messty [58] Field of Search 134/2 3, 25 R, 41, 28 31 of using material handling equlpment such as forceps and tongs.
  • the workpieces for the pickling are placed by hand in the container mounted in swingable manner on the cover of the apparatus and together with the container are lowered into the pickling liquid. Thereupon the cover of the apparatus joined to the swingable container returns in guided manner to its closed position and closes the apparatus so tightly with its sealing ring during the pickling process that no vapor of the pickling fluid can escape outside.
  • the user raises the cover of the apparatus high whereby in guided manner, the workpieces arranged in the swingable container are removed from the pickling liquid.
  • the pickling fluid which is found in the container in' the pickling process flows back through openings on the bottom side of the container in the apparatus.
  • the user turns the cover of the apparatus 180 so that the bottom side of the cover is arranged below the container with the workpieces.
  • the bottom side of the cover serves as a collecting vessel for residues of the pickling fluid still dropping from the container.
  • the user goes with the workpieces to a water tap with a discharge basin. He swings the cover about over the discharge basin with a hand motion and can now cleanse the pickled workpieces in the flowing water jet from remaining residues of pickling liquid,
  • a further possibility in rinsing the workpieces is that the user of the apparatus instead of employing the flowing water jet employs a prepared vessel containing water. In this case he swings the cover of the apparatus about by a hand motion after which he can likewise bririg about an appropriate rinsing by alternating immersion in and raising of the container above the water bath.
  • the now pickled and cleansed workpieces can be withdrawn from the container with the fingers, again without utilization of assisting apparatus such as tongs or forceps and the further working can be carried out.
  • the flat top side of the cover makes possible assembly at the working place so that both hands are free.
  • a further characteristic of the invention is that the pickling fluid condensing on the relatively cool bottom side of the cover is returned again into the deoxidation vessel.
  • FIGURE of the drawing is a crosssectional view of an apparatus for carrying out the invention.
  • a container 1 for a bath e.g., a pickling bath consisting of sulfuric acid or another pickling agent.
  • the container is heated by-a heater 7. Inside the bath container 1 there is situated another container 2 which contains workpieces, e.g., dental tools.
  • the container 2 is swingingly connected with the cover 3 by support 4.
  • the container 2 in its bottom has openings 5 through which it is guaranteed that the pickling fluid can flow around the workpieces to be treated.
  • the cover is raised up whereupon simultaneously the container 2 is removed from the pickling fluid. Since the container 2 is swingably mounted on the supports 4 the person undertaking the working process can bring the treated workpieces in the range of his sight by swinging the container 2 and thereby control whether the surface properties of the treated pieces are unobjectionable.
  • a process of deoxidizing gold or silver on dental workpieces comprising providing a liquid pickling bath in a first container, providing a cover suitable for closing said first container, placing said workpieces in a second smaller container swingably attached to said cover, moving said second container into said first container so that the workpieces are in contact with said pickling bath and the cover closes said first container and thereafter raising the cover and removing said second container from the pickling bath, turning the cover of the first container sufficiently, after the second container is removed from the pickling bath, that the bottom of the cover is below said second container, and
  • a process according to claim 1 comprising the subsequent step of rinsing the workpieces in said second container with water.
