Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A projector component for use when viewing image pages and the detail materials thereof that are presented in ordered arrangement at a reduced size on a film strip comprising a support body, a magnifying lens mounted in said body, a high intensity light source supported by said body and projecting a beam of light therefrom along an axis angularly disposed with respect to the axis of said lens, a pair of film gates movably moUnted on said body adjacent said lens to intercept light from said light source and providing a receptacle for said film strip between said film gates, a selective reflector in the light path intermediate said light source and lens for differentially directing visible light and infra-red heat energy whereby the heat energy radiates along a path directed away from said lens, adjusting means between a first film gate and said body, and an elastic element disposed for urging said second film gate toward contact with said film strip and the said first film gate in its adjusted positions whereby the distance between the film strip in said film gate receptacle and said lens may be closely adjusted.
Claim 2
Dependent Claim
191 words
A projector component for use when viewing image pages and the detail materials thereof that are presented in ordered arrangement at a reduced size on a film strip comprising a support body, a magnifying lens mounted in said body, a high intensity light source supported by said body and projecting a beam of light therefrom along an axis angularly disposed with respect to the axis of said lens, a pair of film gates movably moUnted on said body adjacent said lens to intercept light from said light source and providing a receptacle for said film strip between said film gates, a selective reflector in the light path intermediate said light source and lens for differentially directing visible light and infra-red heat energy whereby the heat energy radiates along a path directed away from said lens, adjusting means between a first film gate and said body, and an elastic element disposed for urging said second film gate toward contact with said film strip and the said first film gate in its adjusted positions whereby the distance between the film strip in said film gate receptacle and said lens may be closely adjusted.
Claim 3
Dependent Claim
28 words
Structure as set forth in claim 1 wherein said film gates are of heat conductive material providing an additional heat sink for the protection of said film strip.
Claim 4
Dependent Claim
22 words
Structure as set forth in claim 2 wherein fin type extensions are provided on said film gate providing added heat dissipating capability.
Claim 5
Dependent Claim
24 words
Structure as set forth in claim 3 wherein the finned extensions of said film gate component have a cam surface providing said adjusting means.
Claim 6
Dependent Claim
49 words
Structure as set forth in claim 2 and further comprising an electric circuit interconnected to said film gates whereby an electric signal will be transmitted therebetween when the film gates are in contact or interrupted when the film gates are separated as when the film strip is disposed therebetween.
Claim 7
Dependent Claim
43 words
Structure as set forth in claim 5 wherein said electric circuit is used for the control of said light source and further comprising additional circuit means whereby the light will be on only when a film strip is disposed between said film gates.
Claim 8
Dependent Claim
50 words
Structure as set forth in claim 6 wherein said additional circuit means is inclusive of time delay components interconnected to said fan whereby the fan remains on an additional period after removal of the film strip and the consequent turning off of said lamp whereby preaccumulated heat may be dissipated.
