  • Heatable appliance for personal use
    Patent number: 5394862
    Abstract: The invention is directed to a heatable appliance, in particular a curling iron (10), including a device (18) for flameless combustion of a fuel/air mixture and an associated activation device (20, 21) for initiating the flameless combustion action, wherein the device (18) comprises a carrier means coated with a catalytically active material. According to the present invention, the carrier means is configured as a stable carrier structure (28) comprised in particular of a metal foil provided with perforations (32) or a wire lattice. At least one metal wire (36) preferably catalytically coated is arranged on the carrier structure (28) to serve as a starter catalyst (34). By this means, the activating ability of the catalytically coated carrier structure (28) is promoted.

  • Heatable appliance for personal use
    Patent number: 5320089
    Abstract: The invention is directed to a heatable appliance for personal use, in particular a hair-care appliance, including a device for the flameless combustion of a fuel/air mixture and an associated activation device for initiating its flameless combustion, wherein the device includes a stable carrier structure 28 of a mass m.sub.T and a density s.sub.T. The carrier structure 28 is provided with a coating having a specific surface area O.sub.B (according to the BET method) and a mass m.sub.B, the coating carrying a catalytically active material of a mass m.sub.K. In order to ensure a high mechanical stability, a satisfactory activation ability and at the same time a high resistance to poisoning of the catalyst, the ratio ##EQU1## is set at values in the following range:0.3.times.10.sup.6 .ltoreq.delta.ltoreq.30.times.10.sup.6.
