  • Patent number: 5673710
    Abstract: The invention is directed to an appliance for treating hair (1), which is comprised of a handle section (2) and a heatable hair treatment section (3). The section (3) possesses an approximately tubular bristle mounting member (4) which is assembled from two half shells (7, 8). Projecting outwardly from the half shell (7) are bristles (5), and the half shell (8) is equipped with rib members (6). The radius (R1) of the cross section of the bristled half shell (7) is smaller than the radius (R2) of the cross section of the ribbed half shell (8). These different radii (R1, R2) enable a user both to form waves with long or medium long hair and to treat short hair in the area close to the scalp. The larger radius may be used for large-volume waves in particular where long hair is involved, while the smaller radius is suitable in particular for treating short hair as well as hair in the area close to the scalp.

  • 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.

  • 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.
