Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
88 words
A transmission belt comprising a flexible elongated body portion comprising at least one elongated body element on which a series of blocks are positioned, in which the elongated flexible body element comprises a central cable element convered by a plastic jacket, and in which the blocks are each comprised of a body portion comprising opposing sides, each side comprising a surface portion normally in a plane, in which said planes form, in cross section, an outline corresponding to at least a portion of the lines of a V.
Claim 2
Dependent Claim
88 words
A transmission belt comprising a flexible elongated body portion comprising at least one elongated body element on which a series of blocks are positioned, in which the elongated flexible body element comprises a central cable element convered by a plastic jacket, and in which the blocks are each comprised of a body portion comprising opposing sides, each side comprising a surface portion normally in a plane, in which said planes form, in cross section, an outline corresponding to at least a portion of the lines of a V.

Claim 13
Dependent Claim
13 words
The transmission belt as claimed in claim 11 formed in an endless loop.
Claim 14
Dependent Claim
29 words
The transmission belt as claimed in claim 12, formed in an endless loop by means of a splice including ends of the cable clamped together within a crimped bushing.
Claim 15
Dependent Claim
20 words
