The invention relates to a gas flowrate adjustment and limitation device for a liquefied-gas lighter of the type having at least one compressible element traversed by the gas, and means of compressing this element to a greater or lesser degree depending on the desired flowrate. This device is characterized by having a permeable disk 12, the periphery of which is in contact with a coaxial permeable crown 7, by the gas passage in disk 12 and crown 7 being substantially radial, and by essentially the total surface area of each of the outer surfaces of said disk 12 and said crown 7 being in contact with some element of the device or lighter.

The present invention relates to a stratified, corrosion-resistant complex comprising a metal substrate and an outer layer made of a noble material. According to the invention the substrate is composed of an alloy having, by weight at least 45% nickel, at least 7% chromium, and at least 7% molybdenum, all the other components of the substrate representing at most 15% of the alloy. The invention is particularly useful for making the backs of watch cases.

Stratified corrosion-resistant complex

A liquefied gas apparatus, in particular a gas lighter for smokers, is disclosed, utilizing a vaporizer-pressure reducer assembly including a pressure reducing device situated generally within a vaporizer. All solid materials with which the assembly is in contact have a thermal conductivity in the range 0.3 to 5 kcal/m/h/.degree. C.
