Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
47 words
A device incorporating a bearing which is lubricated with a ductile metal ally, characterized in that the metal alloy consists of a metallic matrix which is alloyed with 0.1-5 at.% of at least one alloy which has a higher surface tension than the metal(s) of the matrix.
Claim 2
Independent Claim
47 words
A device incorporating a bearing which is lubricated with a ductile metal ally, characterized in that the metal alloy consists of a metallic matrix which is alloyed with 0.1-5 at.% of at least one alloy which has a higher surface tension than the metal(s) of the matrix.
Claim 3
Dependent Claim
23 words
A device as claimed in Claim 1, characterized in that the matrix consists of lead which is alloyed with 0.1-4 at.% of copper.
