Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
An insert for insertion into a circularly cross-sectioned sample tube for use in nuclear magnetic resonance spectrometry comprising, two spaced end plugs, said plugs having arcuate sides to be positioned in a heat exchange relationship adjacent the inner surface of sample tube when inserted therein, said end plugs having venting means for allowing the passage of fluids when the insert is moved into a sample tube having a sample, an elongate circular rod positioned between and connected to said end plugs, and said end plugs and rod being of beryllium oxide.
Claim 2
Dependent Claim
91 words
An insert for insertion into a circularly cross-sectioned sample tube for use in nuclear magnetic resonance spectrometry comprising, two spaced end plugs, said plugs having arcuate sides to be positioned in a heat exchange relationship adjacent the inner surface of sample tube when inserted therein, said end plugs having venting means for allowing the passage of fluids when the insert is moved into a sample tube having a sample, an elongate circular rod positioned between and connected to said end plugs, and said end plugs and rod being of beryllium oxide.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 including attachment means connected to the top plug for inserting and removing the insert from a sample tube.
Claim 4
Dependent Claim
13 words
The combination of claim 1 with a sample tube comprised of beryllium oxide.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1 including a heatsink grease positioned on the sides of the end plugs for providing a thermal contact with the tube when inserted.
Claim 6
Dependent Claim
21 words
The apparatus of claim 1 wherein one of the plugs includes a guide surface on its end remote from the rod.
Claim 7
Dependent Claim
155 words
An insert for insertion into a circularly cross-sectioned sample tube for use in nuclear magnetic resonance spectrometry for reducing temperature variations in the sample and dispersing heat generated therein comprising, two spaced end plugs, said plugs having arcuate sides to mate with the interior of the sample tube for providing thermal transmission when the insert is inserted into the tube, said end plugs having a venting passage for allowing flow of fluids pass the plugs when the insert is moved into a sample in the tube, an elongate circular rod positioned between and connected to said end plugs and positioned to be coaxially positioned in the sample tube, said rod having a cross-sectional area of less than the end plugs for providing an annular sample chamber when positioned in a sample tube, and said end plugs and said rod being of beryllium oxide for conducting heat from and reducing temperature variations in the sample tube.
Claim 8
Dependent Claim
155 words
An insert for insertion into a circularly cross-sectioned sample tube for use in nuclear magnetic resonance spectrometry for reducing temperature variations in the sample and dispersing heat generated therein comprising, two spaced end plugs, said plugs having arcuate sides to mate with the interior of the sample tube for providing thermal transmission when the insert is inserted into the tube, said end plugs having a venting passage for allowing flow of fluids pass the plugs when the insert is moved into a sample in the tube, an elongate circular rod positioned between and connected to said end plugs and positioned to be coaxially positioned in the sample tube, said rod having a cross-sectional area of less than the end plugs for providing an annular sample chamber when positioned in a sample tube, and said end plugs and said rod being of beryllium oxide for conducting heat from and reducing temperature variations in the sample tube.
Claim 9
Dependent Claim
39 words
The apparatus of claim 6 including, attachment means connected to one of the plugs for inserting and removing the insert from a sample tube, and guide means on other of said plugs for guiding the insert into a tube.
