  • Electrical power resistor
    Patent number: 9117575
    Abstract: An electric power resistor has a stack of a plurality of resistor plates of metal. Each resistor plate has at least one meandering structure which is formed by a plurality of alternately mutually connected transverse webs. Resistor plates following one another in the stack direction are rotated by 90° with respect to one another.
    Type: Grant

  • Inhalation unit
    Patent number: 8191555
    Abstract: The invention relates to a heating device (9), for a mobile inhalation unit for the inhalation of active agents, comprising a heating wire (15), with two connector ends (23, 31) for the introduction of electrical energy and a thermal reservoir (13, 17) for heating air flowing along the thermal reservoir, whereby the thermal reservoir may be heated by means of the heating wire. The heating wire has a temperature coefficient of at least 0.001 K?1. The invention further relates to an inhalation unit with such a heating device and a method for heating a thermal reservoir on such a heating device.
