Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
89 words
A uniform temperature thermocouple reference apparatus having, in combination, an array of similar metal terminal blocks each provided with means to connect two conductors, each terminal block being connected to adjacent blocks with elements of high thermal conductivity but low electrical conductivity disposed therebetween so that the terminal blocks are electrically insulated from one another but are at substantially the same temperature, and conductor means connected to certain of said blocks and composed of material dissimilar to that of the associated blocks for effecting thermocouple reference junctions therewith .
Claim 2
Dependent Claim
89 words
A uniform temperature thermocouple reference apparatus having, in combination, an array of similar metal terminal blocks each provided with means to connect two conductors, each terminal block being connected to adjacent blocks with elements of high thermal conductivity but low electrical conductivity disposed therebetween so that the terminal blocks are electrically insulated from one another but are at substantially the same temperature, and conductor means connected to certain of said blocks and composed of material dissimilar to that of the associated blocks for effecting thermocouple reference junctions therewith .
Claim 3
Dependent Claim
32 words
A uniform temperature reference apparatus as claimed in claim 1 and in which the array of blocks, except for the means to connect said conductors, is embedded in an electrically insulating medium.
Claim 4
Dependent Claim
35 words
A uniform temperature reference apparatus as claimed in claim 1 and in which the front and rear faces of the terminal blocks contain apertures, for conductor terminals to establish electrical connection with the terminal blocks.
Claim 5
Dependent Claim
24 words
A uniform temperature reference apparatus as claimed in claim 3 and in which said elements are disposed between adjacent sides of adjacent terminal blocks.
Claim 6
Dependent Claim
50 words
A uniform temperature reference apparatus as claimed in claim 3 and in which said terminal blocks are of copper and the front face conductor terminals are provided with thermocouple wire input connections constituting said conductor means to form said reference junctions between said thermocouple wires and the corresponding terminal blocks.
Claim 7
Dependent Claim
25 words
A uniform temperature reference apparatus as claimed in claim 5 and in which the rear face conductor terminals are provided with copper wire output connections.
Claim 8
Dependent Claim
28 words
A uniform temperature reference apparatus as claimed in claim 6 and in which monitoring means is thermally connected with said array to indicate the said uniform temperature thereof.
Claim 9
Dependent Claim
41 words
A uniform temperature reference apparatus as claimed in claim 1 and in which the said array comprises a plurality of transverse branches of terminal blocks extending on opposite sides of and from successive points along a common longitudinally extending metal bar.
Claim 10
Dependent Claim
40 words
A uniform temperature reference apparatus as claimed in claim 1 and in which said array is disposed within an enclosure provided with thermal insulation means disposed between the array and the ambient environment at the outer walls of the enclosure.
Claim 11
Dependent Claim
40 words
A uniform temperature reference apparatus as claimed in claim 9 and in which means is provided for supplying greater thermal conductance between said ambient environment and the central portion of the said array than at the ends of the array.
Claim 12
Dependent Claim
65 words
A uniform temperature reference apparatus as claimed in claim 10 and in which said last-named means comprises a recessed section in at least one of said outer walls of the enclosure opposite said central portion of the said array providing less of said thermal insulation between the outer walls of the enclosure and said central portion of the said array than at the ends thereof.
Claim 13
Dependent Claim
27 words
A uniform temperature reference as claimed in claim 1 and in which said terminal blocks are of copper and said elements comprise berylium oxide wafers conneCted therebetween.
Claim 14
Dependent Claim
