Abstract

Abstract There is disclosed an electrically activated infrared source assembly having a frame member with a pair of substantially parallel sides adapted to receive strands of an elongated wire stretched repeatedly therebetween in a serpentine configuration, each side having a curved surface thereon adapted to receive tangentially thereto and to support thereover end portions of the wire strands stretched from the other side, the curved surface having a multiplicity of grooves therealong adapted to accept the end portions of the wire strands at the point of tangential contact for maintaining the stretched wire strands between the sides in a spaced relationship one to another, each of the curved surfaces having a plurality of projections therealong adapted to engage therearound the end portions of the wire strands. An elongated wire is stretched back and forth in a serpentine configuration between the sides, around the projections and along the grooves, the wire being adapted to be connected to an electrical source of pulsating energy and to be activated thereby to radiate pulsating infrared energy. Each end portion of the wire strands is bonded around a projection up to but not including the region of the grooves.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 165 words
An infrared source assembly comprising: a frame member having a pair of substantially parallel sides adapted to receive segments of an elongated wire stretched repeatedly therebetween in a serpentine configuration, each side having a curved surface thereon adapted to receive tangentially thereto and to support thereover end portions of the wire strands stretched therebetween, said curved surface having a multiplicity of ribs therealong with grooves therebetween adapted to receive and accept the wire strands at the point of tangential contact for maintaining the stretched wire strands between said sides in a spaced relationship one to another, each of said curved surfaces having a plurality of projections therealong adapted to engage therearound end portions of the serpentine loops of stretched wire; and an elongated wire stretched back and forth in a serpentine configuration between said sides, around said projections and along said grooves, said wire adapted to be connected to an electrical source of pulsating energy and to be activated thereby to radiate pulsating infrared energy.
Claim 2
Dependent Claim 165 words
An infrared source assembly comprising: a frame member having a pair of substantially parallel sides adapted to receive segments of an elongated wire stretched repeatedly therebetween in a serpentine configuration, each side having a curved surface thereon adapted to receive tangentially thereto and to support thereover end portions of the wire strands stretched therebetween, said curved surface having a multiplicity of ribs therealong with grooves therebetween adapted to receive and accept the wire strands at the point of tangential contact for maintaining the stretched wire strands between said sides in a spaced relationship one to another, each of said curved surfaces having a plurality of projections therealong adapted to engage therearound end portions of the serpentine loops of stretched wire; and an elongated wire stretched back and forth in a serpentine configuration between said sides, around said projections and along said grooves, said wire adapted to be connected to an electrical source of pulsating energy and to be activated thereby to radiate pulsating infrared energy.
Claim 3
Dependent Claim 50 words
The infrared source assembly described in claim 1 further including a bonding substance covering each and every projection and the portion of said wire therearound up to but not including the region of said grooves, thereby securing said wire to said curved surface of each side of said frame member.
Claim 4
Dependent Claim 16 words
The infrared source assembly described in claim 2 wherein said bonding substance is a potting cement.
Claim 5
Dependent Claim 17 words
The infrared source assembly described in claim 3 wherein said wire is tungsten with substantially 3% rhenium.
Claim 6
Dependent Claim 20 words
The infrared source assembly described in claim 4 wherein each of said pair of sides is an anodized aluminum alloy.
Claim 7
Dependent Claim 49 words
The infrared source assembly described in claim 1 wherein said frame member includes a spacer member between said pair of parallel sides, said spacer member having an opening therethrough with a shoulder therearound, said opening substantially being located adjacent said stretched strands of said wire between said parallel sides.
Claim 8
Dependent Claim 39 words
The infrared source assembly described in claim 6 further including a mirror mounted on said shoulder of said spacer member adjacent said stretched strands of said wire for reflecting the infrared energy incident thereon from said stretched wire strands.
Claim 9
Dependent Claim 20 words
The infrared source assembly described in claim 7 wherein said spacer member is made of a material such as kovar.
Claim 10
Dependent Claim 29 words
The infrared source assembly described in claim 1 wherein said multiplicity of grooves are formed by the juncture of small ribs aligned side by side along said curved surface.
