Abstract
Abstract A frame assembly for use in combination with a sheet of liquid crystals and a camera for the purpose of facilitating the permanent record of thermal variation of living body tissues. The frame assembly comprises a base including structure for operatively disposing a sheet of liquid crystals at one end and a camera at the other. A movable light source positioning arm is disposed on the base for the purpose of directing illumination onto the sheet of crystals of which a photograph is to be taken.

Total Claims: 8
Claim 1
Independent Claim
201 words
A liquid crystal thermograph frame assembly for use in combination with a sheet of liquid crystals and a camera for obtaining a permanent record of thermal variation of living tissue, said frame assembly comprising: base means comprising first and second planar segments disposed in abutting, non-linear intersecting relation to each other; crystal receiving means operatively disposed on the free end of said first planar segment; liquid crystal holder means removably attachable to said base means by said crystal receiving means, said liquid crystal holder means comprising first and second frame elements hingedly attached to each other and corresponding first and second apertures formed therein whereby a sheet of liquid crystals may be operatively retained between said first and second frame elements and operatively mounted on said free end of said first planar segment; camera mounting means formed on said second planar segment in substantially opposed relation to said crystal receiving means whereby a camera may be mounted thereon; and light source positioning means movably disposed on said second planar segment, at least a portion of said light source positioning means being disposable between said crystal receiving means and said camera mounting means whereby the sheet of liquid crystals may be illuminated.
Claim 2
Dependent Claim
201 words
A liquid crystal thermograph frame assembly for use in combination with a sheet of liquid crystals and a camera for obtaining a permanent record of thermal variation of living tissue, said frame assembly comprising: base means comprising first and second planar segments disposed in abutting, non-linear intersecting relation to each other; crystal receiving means operatively disposed on the free end of said first planar segment; liquid crystal holder means removably attachable to said base means by said crystal receiving means, said liquid crystal holder means comprising first and second frame elements hingedly attached to each other and corresponding first and second apertures formed therein whereby a sheet of liquid crystals may be operatively retained between said first and second frame elements and operatively mounted on said free end of said first planar segment; camera mounting means formed on said second planar segment in substantially opposed relation to said crystal receiving means whereby a camera may be mounted thereon; and light source positioning means movably disposed on said second planar segment, at least a portion of said light source positioning means being disposable between said crystal receiving means and said camera mounting means whereby the sheet of liquid crystals may be illuminated.
Claim 3
Dependent Claim
47 words
A liquid crystal thermograph frame assembly as in claim 1 wherein said light source positioning means comprises arm means, one end of said arm means being movably attached to said second planar segment and the other end of said arm means comprising a light source platform means.
Claim 4
Dependent Claim
26 words
A liquid crystal thermograph frame assembly as in claim 2 wherein said one end of said arm means is pivotally attached to said second planar segment.
Claim 5
Dependent Claim
30 words
A liquid crystal thermograph frame assembly as in claim 2 wherein said light source platform means comprises a light shelf movably attached to said other end of said arm means.
Claim 6
Dependent Claim
55 words
A liquid crystal thermograph frame assembly as in claim 1 wherein the effective longitudinal dimension defined by said first and second planar segments is such that a sheet of liquid crystals disposed on said crystal receiving means will lie along the focal plane of the lense of a camera attached to said camera mounting means.
Claim 7
Dependent Claim
32 words
A liquid crystal thermograph frame assembly as in claim 1 wherein said crystal receiving means comprises a plurality of fastening means removably attachable to said three end of said first planar segment.
Claim 8
Dependent Claim
39 words
A liquid crystal thermograph frame assembly as in claim 1 further comprising an auxiliary shelf disposed transversely across said first planar segment in receiving relation to a photograph ejected from an automatic camera disposed on said camera mounting means.
