摘要:
The invention is directed to a bristle for a toothbrush, particularly for an electric toothbrush, and to a method for its manufacture. The bristle is manufactured from a monofilament (5) made of plastic. The bristle has in its cross section at least two zones (6, 7) and at least one point of preferred breaking.

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.
摘要:
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.
