Patent number: 8377382Abstract: A recycling furnace is provided for processing potentially explosive precious metal-containing materials having organic fractions that combust with great energy. The furnace includes a switching facility for alternating operation of two burning-off chambers of the furnace between: (A) pyrolysis or carbonization under protective furnace gas in an atmosphere comprising maximally 6 wt-% oxygen, and (B) oxidative combustion of the organic fractions including carbon. The furnace has indirect heating and a control that determines the end of the pyrolysis or carbonization by a sensor and controls the switching facility to supply air or oxygen to the interior of the furnace. A continuous conveyor for dosing of liquids or liquefied substances during the pyrolysis is controlled by at least one parameter of post-combustion, preferably a temperature sensor. A single waste gas treatment facility is used for thermal post-combustion for the two furnace chambers.Type: GrantFiled: May 1, 2012Date of Patent: February 19, 2013Assignee: Heraeus Precious Metals GmbH & Co.

Patent number: 8355802Abstract: A stimulation electrode is produced having a porous film layer and being partially coated with an insulating parylene (polyparaxylylene) film, whose insulating film has a dielectric breakdown voltage of greater than 100 V. Parylene is deposited on the entire surface of a porous film coating and then partially removed again by plasma. After the partial removal of the parylene, this porous film still has a capacitance of greater than 15 mF/cm2 in a physiological NaCl solution at a frequency of 0.1 Hz. For the stimulation electrode, the transition from the insulating film to the porous film is formed so that the film thickness of the parylene film decreases continuously. In this way, a stimulation electrode having a porous film layer and being partially coated with an insulating parylene film is provided, whose electrode on the non-insulating parylene film-coated surface has a capacitance of greater than 15 mF/cm2 in a physiological NaCl solution at a frequency of 0.Type: GrantFiled: June 17, 2009Date of Patent: January 15, 2013Assignee: Heraeus Precious Metals GmbH & Co.
