  • HEATED HAIR ROLLER Inventors: Bruno P. Morane; Pierre Alexandre.
  • ABSTRACT Heated hair roller comprises reservoir for liquefied gas. a member through which said gas diffuses and expands. and a duct for directing gas from said member against a catalyst.
  • FIG .2
  • HEATED HAIR ROLLER SUMMARY OF THE lNVENTlON in a conventional hair curling process it is customary to wind the damp hair up on rollers and subject them to a certain amount of heat in order to dry the wound up hair and render the waves more permanent.
  • French Pat. No. 1,484.48 l a heating roller is described which comprises a catalyst designed to catalyze the oxidation of a combustible material in the gaseous phase.
  • the combustible material is stored in liquid form in the roller inside a reservoir provided with an expansion valve.
  • the combustible material may advantageously be a hydro-carbon having a low boiling point, such as butane.
  • French Pat. No. 70-29672 proposes an expansion valve for the combustible material comprising an outlet of very small diameter formed, for instance, by a laser beam.
  • the present invention is therefore directed to a new article of manufacture which consists of a heating roller comprising a substantially cylindrical hollow body defining a cylindrical volume which holds both a reservoir for liquefied combustible material under pressure equipped with an expansion valve and a catalyst intended to catalyze upon contact the combustion of the combustible material coming from said reservoir, said catalyst being in contact with the ambient air inside the roller.
  • This roller is characterized by the fact that there is interposed between the reservoir and the catalyst a member which permits a small. substantially constant flow of combustible gas to pass therethrough when subjected to the pressure which prevails in the reservoir. at the end of said member. a rigid duet which collects the output of combustible gas obtained from said member and directs it towards a point in the central zone of the catalyst.
  • the member which permits a small flow of gas to pass therethrough consists of a membrane which is permeable to the combustible gas.
  • This membrane may advantageously conslst of a silicone product and. in particular. dlmethyisllane.
  • the silicone membrane has a thickness between 40 and microns. preferably about 60 microns.
  • the member through which the small flow of gas passes consists of a tablet of porous material such as may be obtained by agglomerating pulverulent products.
  • porous tablets which are particularly valuable are those obtained by compacting a calcium silicate powder, a steatite powder and a graphite powder.
  • the gas flow through the tablet may be regulated by adjusting the pressure drop which takes place during the course of the passage through the tablet by adjusting the thickness of the tablet or the pressure at which the pulverulent material is compacted or sintered, and the granulometry of the pulverulent material selected.
  • the catalyst in a preferred embodiment of the invention the catalyst consists of a tablet, the distance between the end of the duct and the median plane of the catalyst tablet lies between i and 4 millimeters.
  • the duct consists of a section of a hypodermic needle made of stainless steel.
  • the catalyst tablet is supported by a bracket having several arms, one end of each arm supporting the tablet while the other end is connected to a collar attached to the outer wall of the duct. The collar of the bracket is crimped to the duct.
  • the fact that the catalyst tablet is supported by a bracket fixed to the duct itself makes it possible. on the one hand. to locate the catalyst tablet with respect to the end of the duct. and on the other hand. to avoid any connecting support between the catalyst tablet and the wall of the roller.
  • This latter point is important because the use of a connecting support would permit the transmission of localized heat to a zone of the wall of the roller which. on the one hand. might damage the wall in the overheated zone and. on the other hand. involves the risk of producing a zone of excessive heat for the hair wound on the roller.
  • the duct has been spaced or insulated from the combustible material reservoir.
  • roller of the above type characterized by the fact that between the member traversed by a small gas flow and the duct through which said gas flow is evacuated an additional member is interposed.
  • This additiional member is preferably made of an elastomeric material and its base is mounted on the member traversed by the gas while its summit carries the end of the duct.
  • the aforesaid additional member is a nipple made of a rubbery material which is attached along its edge to the entire periphery of the member traversed by a small gas flow.
  • the latter member is itself attached to the edges of the outlet of the reservoir holding the combustible material and crimping is used to seal together the nipple member and reservoir.
  • the additional member between the member traversed by a small gas flow and the duct is a rubbery body comprising axial grooves, one end of which receives the member traversed by a small gas flow and the other end of which receives the terminal portion of the duct through which the gas flow is evacuated.
  • priming means for example a hot point.
  • the device for delivering concentrated energy is an optical concentrator having a short focal length.
  • the device for delivering a concentrated energy is a piezo-electric device which makes it possible to produce a spark at each pressure exerted on the device. said spark supplying to the catalyst an energy preferably between i and 3 millijoules.
  • the supports provided in the axial zone of the roller are radially positioned vanes shaped to conform to the abutment surface of the generator of concentrated energy.

  • FIG. 2 shows in axial section a second embodiment of the invention
