Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 260 words
Hair Styling apparatus comprising: a first tubular member having a hair styling portion with first and second ends and a plurality of apertures there between; a second tubular member having a plurality of nodules arranged in multiple rows and columns about a peripheral surface, said second tubular member being disposed within said first tubular member with said nodules contacting predetermined discrete points (on) substantially at extremities of said hair styling portion of said first tubular member to provide a uniform predetermined spacing between said first and second members and to transfer heat by conduction from said second member to said points on said first member to operate said first tubular member hair styling portion at a predetermined uniform surface temperature; heat reservoir means attached to one end of said second tubular member; heat generating means disposed within said second tubular member in heat transfer contact with said heat reservoir means and said second tubular member for heating said hair styling portion to said predetermined uniform surface temperature; variable temperature control means coupled to said heat generating means for maintaining said hair styling portion at said predetermined temperature; a handle mounted on a first end of said first tubular member; fluid dispensing means mounted on a second end of said first tubular member for supplying a predetermined amount of fluid to said heat reservoir means for vaporization, whereby said vaporized fluid is discharged in a radial direction through said apertures; and clamping means pivotally mounted on said handle to clamp hair against said hair styling portion of said first tubular member.
Claim 2
Dependent Claim 260 words
Hair Styling apparatus comprising: a first tubular member having a hair styling portion with first and second ends and a plurality of apertures there between; a second tubular member having a plurality of nodules arranged in multiple rows and columns about a peripheral surface, said second tubular member being disposed within said first tubular member with said nodules contacting predetermined discrete points (on) substantially at extremities of said hair styling portion of said first tubular member to provide a uniform predetermined spacing between said first and second members and to transfer heat by conduction from said second member to said points on said first member to operate said first tubular member hair styling portion at a predetermined uniform surface temperature; heat reservoir means attached to one end of said second tubular member; heat generating means disposed within said second tubular member in heat transfer contact with said heat reservoir means and said second tubular member for heating said hair styling portion to said predetermined uniform surface temperature; variable temperature control means coupled to said heat generating means for maintaining said hair styling portion at said predetermined temperature; a handle mounted on a first end of said first tubular member; fluid dispensing means mounted on a second end of said first tubular member for supplying a predetermined amount of fluid to said heat reservoir means for vaporization, whereby said vaporized fluid is discharged in a radial direction through said apertures; and clamping means pivotally mounted on said handle to clamp hair against said hair styling portion of said first tubular member.
Claim 3
Dependent Claim 19 words
Hair styling apparatus according to claim 1, wherein said heat generating means include resistance wire responsive to electrical current.
Claim 4
Dependent Claim 25 words
Hair styling apparatus according to claim 2, wherein said resistance wire is embedded in a heat conducting electrical insulator disposed within said second tubular member.
Claim 5
Dependent Claim 50 words
Hair styling apparatus according to claim 2, wherein said variable temperature control means include a temperature sensitive element for moving a selected distance in response to a predetermined change in temperature to interrupt a conductive path for said current to said resistance wire and means for determining said selected distance.
Claim 6
Dependent Claim 38 words
Hair styling apparatus according to claim 1, wherein said fluid dispensing means include a fluid saturated wick and means for moving said fluid saturated wick to contact said heat reservoir means for vaporizing said fluid in said wick.
Claim 7
Dependent Claim 138 words
Hair styling apparatus comprising: a heat conducting hair styling member having an inner surface and an outer surface with a perforated portion; heat generating means disposed within said styling member, said heat generating means being responsive to an electrical signal; means having a plurality of nodules arranged in multiple rows and columns surrounding said heat generating means for conducting heat by conduction from said heat generating means to a plurality of predetermined discrete points on said inner surface of said hair styling member substantially at extremities of said perforated portion to provide a uniform surface temperature along said outer surface of said perforated portion; and fluid dispensing means coupled to said heat conducting styling member for supplying a predetermined amount of fluid to said heat generating means for vaporization, whereas said vaporized fluid is discharged through said apertures.
Claim 8
Dependent Claim 138 words
Hair styling apparatus comprising: a heat conducting hair styling member having an inner surface and an outer surface with a perforated portion; heat generating means disposed within said styling member, said heat generating means being responsive to an electrical signal; means having a plurality of nodules arranged in multiple rows and columns surrounding said heat generating means for conducting heat by conduction from said heat generating means to a plurality of predetermined discrete points on said inner surface of said hair styling member substantially at extremities of said perforated portion to provide a uniform surface temperature along said outer surface of said perforated portion; and fluid dispensing means coupled to said heat conducting styling member for supplying a predetermined amount of fluid to said heat generating means for vaporization, whereas said vaporized fluid is discharged through said apertures.
