Abstract
Abstract A sample holder for selective thermoanalytical analysis of specimens, comprises a receptacle for the specimen and cover means for the receptacle. The cover means provides a labyrinthine path for escape of gases from the sample. This labyrinthine path can be provided by concentric cylindrical elements which permit the gas to escape past alternately opposite edges thereof, or a helical groove in the outer cylindrical periphery of the cover means that defines the labyrinthine path. A thermocouple for continuously detecting the temperature of the sample is disposed in a central recess in the bottom of the vessel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
50 words
A sample holder for selective thermoanalytical tests, comprising a vessel for holding a sample to be tested, cover means closing said container, said cover means defining a labyrinthine path for the escape of gases from said vessel, and means carried by said vessel for detecting the temperature of said sample.
Claim 2
Dependent Claim
50 words
A sample holder for selective thermoanalytical tests, comprising a vessel for holding a sample to be tested, cover means closing said container, said cover means defining a labyrinthine path for the escape of gases from said vessel, and means carried by said vessel for detecting the temperature of said sample.
Claim 3
Dependent Claim
28 words
A sample holder as claimed in claim 1, said cover means comprising a plurality of concentric rings of different heights, and a cover resting atop each said ring.
Claim 4
Dependent Claim
35 words
A sample holder as claimed in claim 2, and inverted cups between said rings, the gases following said labyrinthine path passing between said rings and their covers, and under the edges of said inverted cups.
Claim 5
Dependent Claim
26 words
A sample holder as claimed in claim 1, said cover means comprising a single cover member that defines between itself and said vessel said labyrinthine path.
Claim 6
Dependent Claim
41 words
A sample holder as claimed in claim 4, said single cover having a cylindrical outer periphery disposed within and closely adjacent a cylindrical inner periphery of said vessel, said cylindrical outer periphery having a helical groove therein defining said labyrinthine path.
Claim 7
Dependent Claim
42 words
A sample holder as claimed in claim 1, said cover means comprising a plate disposed within said vessel above a sample therein and a cover closing the vessel and having portions interfitting with portions of said plate to define said labyrinthine path.
Claim 8
Dependent Claim
38 words
A sample holder as claimed in claim 6, said plate having upstanding concentric cylinders thereon and said cover having downwardly depending concentric cylinders that fit between the concentric cylinders of said plate thereby to define said labyrinthine path.
Claim 9
Dependent Claim
40 words
A sample holder as claimed in claim 7, said plate resting on said sample and exposing said sample outwardly of said plate, said cover having a central opening therethrough for escape of gases at the end of said labyrinthine path.
Claim 10
Dependent Claim
19 words
A sample holder as claimed in claim 1, said vessel having a recess therein for said temperature detecting means.
