  • Patent number: 8017890
    Abstract: A touch responsive capacitive control for a smooth surfaced ceramic cooktop provides a continuously variable control voltage which indicates the last touched position on an elongated control surface. An alternating current potential is applied between a transmitter plate and a pair of receiver plates all of which are positioned below the surface of the cooktop. The relative area of overlap between the touching finger and the two receiver plates varies along the length of the control surface, and the resulting change in the relative currents flowing to the two receiver plates is sensed to provide a position indication used to control the cooktop.

  • Patent number: 7964829
    Abstract: An apparatus for forming a bag assembly includes opposing die members. Each die member has a perimeter-welding portion for forming a perimeter-weld of the bag assembly and a tube-welding portion for forming a tube-weld of the bag.

  • Patent number: 7919728
    Abstract: A welding current controlling method is provided for an arc welding process using a consumable electrode and including an alternate repetition of a short-circuiting state and an arc generating state occurring between the consumable electrode and a base material. In the method, a neck detection is performed for the molten electrode in the short-circuiting period of time to determine if a new arc is established between the consumable electrode and the base material. Upon detection of the neck, the welding current is sharply decreased. After the new arc is established, the welding current is increased from a low level to a high level with a predetermined inclination selected for reducing vibration to the molten pool.

  • Patent number: 7910865
    Abstract: An arrangement for controlling induction coils of an induction cooking hob so as to minimize noise production resulting from intermodulation of certain frequencies of operation. The induction coils are operated in two modes, with a first mode at the same frequency fg so to produce a low intermodulation or differential frequency, or at a second mode having a high differential frequency of about 18 kHz. Alternating back and forth between said modes of operation makes it possible to reach predefined average values for the power of the induction coils for a given time period, while at the same time minimizing development of disturbing noise.
