Abstract
Abstract A specimen carrier suitable for physical tests at low and very low temperatures at coated with an electrically insulating layer of chemical compound of the material from which it is made. If the specimen carrier is of aluminum or an aluminum alloy of good thermal conductivity, said layer may be obtained by eloxation. The wire of a resistance thermometer is wound around the part of the specimen carrier which does not receive the specimen. The thermometer wire is connected with the specimen carrier for example by cementing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A specimen carrier of good thermal conductivity which is suitable for physical tests at low and lowest temperatures and is connected to a resistance thermometer for measuring the temperature of the specimen and to a medium for cooling both the carrier and the specimen, characterized in that the carrier surface which is not connected with the cooling medium and does not serve for carrying the specimen is coated at least partly with an electrically insulating layer of a chemical compound of the material from which the carrier is made, and that at least part of the insulation-coated surface is surrounded by a coil of the resistance thermometer.
Claim 2
Dependent Claim
107 words
A specimen carrier of good thermal conductivity which is suitable for physical tests at low and lowest temperatures and is connected to a resistance thermometer for measuring the temperature of the specimen and to a medium for cooling both the carrier and the specimen, characterized in that the carrier surface which is not connected with the cooling medium and does not serve for carrying the specimen is coated at least partly with an electrically insulating layer of a chemical compound of the material from which the carrier is made, and that at least part of the insulation-coated surface is surrounded by a coil of the resistance thermometer.
Claim 3
Dependent Claim
18 words
A specimen carrier as claimed in claim 1, wherein the thermometer wire is rigidly connected with the carrier.
Claim 4
Dependent Claim
17 words
A specimen carrier as claimed in claim 2, wherein the thermometer wire is cemented to the carrier.
Claim 5
Dependent Claim
22 words
A specimen carrier as claimed in claim 3, wherein a helical groove is provided in a carrier for receiving the thermometer wire.
Claim 6
Dependent Claim
20 words
A specimen carrier as claimed in claim 4, characterized in that it is made from aluminum or an aluminum alloy.
Claim 7
Dependent Claim
16 words
A specimen carrier as claimed in claim 5, characterized in that it is a hollow body.
Claim 8
Dependent Claim
23 words
A specimen carrier as claimed in claim 6, characterized by a rod of German silver located between the carrier and the colling means.
