Abstract
Abstract A hair curler containing a supply of fuel, preferably liquefied fuel such as butane or propane, and a nozzle for releasing gaseous fuel from the supply and for providing a mixture of said fuel and an oxygen containing gas, preferably air, so as to provide a flow or current of a gaseous combustible fuel mixture, which is directed to an area within the hair curler where the fuel of the mixture is oxidated or burned in the presence of an oxidation catalyzing material whereby heat is generated within the curler.

Claim 2
Dependent Claim
68 words
In a hair curler having means for storing a supply of fuel in said curler, means for releasing fuel in gaseous form from the supply and means for catalyzing an oxidation of the released gaseous fuel so as to generate heat, the improvement that said fuel releasing means comprise a nozzle for directing a flow or current of gaseous fuel from said fuel supply to said catalyzing means.
Claim 3
Dependent Claim
40 words
A hair curler according to claim 1, further comprising means for introducing an oxygen containing gas into said flow of gaseous fuel from said nozzle so as to provide a gas mixture combustible in the presence of said catalyzing means.
Claim 4
Dependent Claim
41 words
A hair curler according to claim 2, wherein said oxygen introducing means comprise injector means positioned in alignment with said nozzle at the down stream end thereof for introducing oxygen containing gas into the flow of gaseous fuel by injector effect.
Claim 5
Dependent Claim
22 words
A hair curler according to claim 2, wherein said nozzle defines a nozzle opening the diameter of which is 15-80 Mu .
Claim 6
Dependent Claim
20 words
A hair curler according to claim 4, wherein said nozzle openings has been provided in said plate by laser light.
Claim 7
Dependent Claim
49 words
A hair curler accordiNg to claim 2 wherein said catalyzing means comprise a first catalyst having a relatively long useful life and a second and more active catalyst having a shorter useful life, said first catalyst being positioned upstream to said second catalyst in the flow of gas mixture.
Claim 8
Dependent Claim
40 words
A hair curler according to claim 6, wherein said first catalyst defines the inner surface of a channel or duct portion for said flow of gas mixture, said second catalyst being placed at the downstream end of said duct portion.
Claim 9
Dependent Claim
36 words
A hair curler according to claim 6, wherein said second catalyst comprises a filament of an oxidation catalyzing material for initiating oxidation of the gaseous fuel by heating said filament through supplying an electrical current thereto.
Claim 10
Dependent Claim
63 words
A hair curler according to claim 2, further comprising means for introducing a noncombustible gas or gas mixture into the flow of gas having passed the catalysts in order to obtain that the resulting gas mixture flow leaving the curler is nonflammable even when for some reason no oxidation of the gaseous fuel emitted by the nozzle has taken place in the curler.
Claim 11
Dependent Claim
20 words
A hair curler according to claim 6, wherein said first catalyst comprises aluminum oxide and said second catalyst comprises platinum.
Claim 12
Dependent Claim
82 words
A hair curler according to claim 2, wherein said supply of fuel is present in a liquid as well as in a gaseous state, said fuel releasing means further comprising a porous mass positioned between said fuel supply and said nozzle in such a manner that the fuel has to penetrate said porous mass in order to reach the opening of the nozzle, whereby releasing of the fuel in a gaseous state is secured and clogging of the nozzle opening is prevented.
Claim 13
Dependent Claim
44 words
A hair curler according to claim 11, further comprising wick means contacting said liquid phase of the fuel supply and the porous mass, respectively, so as to secure moistening of said porous mass with liquid fuel phase in all positions of the hair curler.
Claim 14
Dependent Claim
29 words
A hair curler according to claim 11, wherein said porous mass is made from a material selected from the group consisting of pulp, paper, ceramic materials and sintered metals.
Claim 15
Dependent Claim
32 words
A hair curler according to claim 2, further comprising heat insulating material arranged so as to substantially reduce transfer of heat generated by said oxidation of fuel to said supply of fuel.
Claim 16
Dependent Claim
96 words
A hair curler comprising a container for containing at an elevated pressure a supply of a liquefied combustible gas being in a gaseous state at atmospheric pressure and temperature conditions, valve means permitting loading of said container with liquefied gas, a nozzle communicating with said container and comprising an air intake, said nozzle being adapted to direct a current or flow of a mixture of air and combustible gas into an internal space defined in said curler, and catalyzing means arranged in said space for catalyzing an oxidation of combustible gas in said flow or current.
Claim 17
Dependent Claim
96 words
A hair curler comprising a container for containing at an elevated pressure a supply of a liquefied combustible gas being in a gaseous state at atmospheric pressure and temperature conditions, valve means permitting loading of said container with liquefied gas, a nozzle communicating with said container and comprising an air intake, said nozzle being adapted to direct a current or flow of a mixture of air and combustible gas into an internal space defined in said curler, and catalyzing means arranged in said space for catalyzing an oxidation of combustible gas in said flow or current.
Claim 18
Dependent Claim

Claim 19
Dependent Claim
88 words
A hair curler according to claim 15, wherein said catalyzing means comprises a first catalyst having a relatively long useful life and a second and more active catalyst having a shorter useful life, said first catalyst being arranged closer to the nozzle opening then said second catalyst, whereby the initial oxidation of the gas in said flow or current may be catalyzed by said second catalyst, whereas the oxidation may by catalyzed by said first catalyst, the catalyzing process once having been started, thereby sparing said second catalyst.
Claim 20
Dependent Claim
38 words
A hair curler according to claim 17, wherein said second catalyst comprises a filament, means being provided for supplying an electrical current to the filament in order to heat the same, whereby initiation of the oxidation is facilitated.
