Patent number: 10167527Abstract: The invention relates to a method for the progressive induction surface hardening of a closed curve trace of a workpiece, the closed curve trace and a hardening device being moved relative to one another in a feed mode to harden the closed curve trace starting from an initial zone to an end zone, an unhardened soft zone being provided. According to the invention, the workpiece is provided with a marking, the hardening device having a sensor for detecting said marking. The curve trace and the hardening device are moved relative to one another along the treatment direction until the senor detects the marking. Once the marking is detected, another movement takes place in the treatment direction before the hardening device is activated, the curve trace being hardened by the relative movement. The marking is again detected by means of the sensor and the hardening device is then deactivated. The invention also relates to an arrangement which is suitable for carrying out the method described.Type: GrantFiled: February 6, 2013Date of Patent: January 1, 2019Assignee: THYSSENKRUPP ROTHE ERDE GMBHInventors: Marco Burtchen, Mathieu Langels, Bernd Stakemeier

Patent number: 10154545Abstract: An induction hob including a first heating region with a first induction coil and a second heating region with a second induction coil is provided. First and second resonant converters drive an AC current through the first and second induction coils. The first and second resonant converters form a half-bridge resonant converter that is continuously driven such that a direction of current flow through the first induction coil and the second induction coil is alternating. The half-bridge resonant converter controls the output power of the first and second heating regions by varying the frequency of the AC current through the respective induction coil. The first and second resonant converters have different resonance frequencies such that the resonance frequency of the first resonant converter is at least 1.4 times higher than the resonance frequency of the second resonant converter.Type: GrantFiled: June 30, 2014Date of Patent: December 11, 2018Assignee: Electrolux Appliances AktiebolagInventors: Svend Erik Christiansen, Laurent Jeanneteau, Alex Viroli, Luca Zannoni
