Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
An immersion sampler device comprising an immersible body structure with wall portions defining side and end walls of a cavity for the reception of a sample of molten material and wall portions defining an entrance passage thereto wherein said entrance passage has one end disposed at the immersion end of said body structure beyond all sources of contamination of said sample by said sampler device and said entrance passage extends into said cavity at least one quarter of an inch to prevent loss of sample from said cavity.
Claim 2
Dependent Claim
88 words
An immersion sampler device comprising an immersible body structure with wall portions defining side and end walls of a cavity for the reception of a sample of molten material and wall portions defining an entrance passage thereto wherein said entrance passage has one end disposed at the immersion end of said body structure beyond all sources of contamination of said sample by said sampler device and said entrance passage extends into said cavity at least one quarter of an inch to prevent loss of sample from said cavity.
Claim 3
Dependent Claim
168 words
An immersion sampler device comprising a tubular member, a heat destructible protective cap, a multi-element body structure supported in an immersion end of said tubular member, said body structure having wall portions defining side and end of walls of a cavity for reception of a sample of molten material and wall structure defining an entrance passage thereto, and a heat sensing means disposed in said cavity and spaced from the walls thereof a distance adequate accurately to sense the temperature of molten material in said cavity as it cools, one end of said entrance passage being disposed between said cap and the immersion end of said body structure in avoidance of contamination of said sample by said body structure and the other end of said entrance passage being disposed between said end walls of said cavity for discharge of molten material into said cavity at a location spaced above the heat sensing means to insure that the heat sensing means is surrounded by the sample of molten material.
Claim 4
Dependent Claim
168 words
An immersion sampler device comprising a tubular member, a heat destructible protective cap, a multi-element body structure supported in an immersion end of said tubular member, said body structure having wall portions defining side and end of walls of a cavity for reception of a sample of molten material and wall structure defining an entrance passage thereto, and a heat sensing means disposed in said cavity and spaced from the walls thereof a distance adequate accurately to sense the temperature of molten material in said cavity as it cools, one end of said entrance passage being disposed between said cap and the immersion end of said body structure in avoidance of contamination of said sample by said body structure and the other end of said entrance passage being disposed between said end walls of said cavity for discharge of molten material into said cavity at a location spaced above the heat sensing means to insure that the heat sensing means is surrounded by the sample of molten material.
Claim 5
Dependent Claim
32 words
An immersion sampler device according to claim 2 wherein said sampler includes condition sensing means disposed exteriorly of said body structure for contact with a bath of molten material when immersed therein.
Claim 6
Dependent Claim
37 words
An immersion sampler device according to claim 2 wherein said sampler additionally includes a second heat sensing means disposed exteriorly of said body structure for sensing the temperature of a bath of molten material when immersed therein.
Claim 7
Dependent Claim
15 words
An immersion sampler device according to claim 2 wherein said cap is of deoxidizing material.
Claim 8
Dependent Claim
21 words
An immersion sampler device according to claim 2 wherein said tube is a tube of fused quartz or heat resistant glass.
Claim 9
Dependent Claim
36 words
An immersion sampler device according to claim 2 wherein some of said wall portions defining walls of said cavity are of a material which is pOrous for passage of gaseous materials therethrough for venting said cavity.
