Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
In a method of making an endless power transmission belt construction or the like formed of material that is mainly polymeric material and that has been cut from an annular belt sleeve, the method comprising the steps of forming a tension section, forming a compression section, forming a load-carrying section intermediate said tension section and said compression section, and orienting at least part of the material of at least one of said sections, the improvement wherein said step of orienting comprises the step of orienting said part of said material by the force of field line means imposed thereon while said material is in liquid form and is in the belt sleeve form thereof.
Claim 2
Dependent Claim
114 words
In a method of making an endless power transmission belt construction or the like formed of material that is mainly polymeric material and that has been cut from an annular belt sleeve, the method comprising the steps of forming a tension section, forming a compression section, forming a load-carrying section intermediate said tension section and said compression section, and orienting at least part of the material of at least one of said sections, the improvement wherein said step of orienting comprises the step of orienting said part of said material by the force of field line means imposed thereon while said material is in liquid form and is in the belt sleeve form thereof.
Claim 3
Dependent Claim
43 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 wherein said step of orienting causes said part of said material to be oriented substantially parallel to the longitudinal axis of said belt construction.
Claim 4
Dependent Claim
43 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 wherein said step of orienting causes said part of said material to be oriented substantially transverse to the longitudinal axis of said belt construction.
Claim 5
Dependent Claim
42 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 wherein said step of orienting causes at least part of the material of two of said sections to be oriented in different directions.
Claim 6
Dependent Claim
35 words
A method of making an endless power transmission belt construction or the like as set forth in claim 4 wherein said step of orienting causes said different directions to be substantially 90° to each other.
Claim 7
Dependent Claim
50 words
A method of making an endless power transmission belt construction or the like as set forth in claim 5 wherein one of said two sections is said load-carrying section and said step of orienting causes its said direction to be substantially parallel to the longitudinal axis of said belt construction.
Claim 8
Dependent Claim
34 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of forming said part of said material to comprise metallic material.
Claim 9
Dependent Claim
41 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of forming said part of said material to comprise a liquid crystalline material that has a nematic mesophase.
Claim 10
Dependent Claim
35 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of forming said part of said material to comprise a polyferrocene material.
Claim 11
Dependent Claim
42 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of forming said polymeric material of said one section to comprise said part thereof and have a nematic mesophase.
Claim 12
Dependent Claim
32 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of creating said field line means with magnet means.
Claim 13
Dependent Claim
32 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of creating said field line means with electromagnet means.
Claim 14
Dependent Claim
33 words
A method of making an endless power transmission belt construction or the like as set forth in claim 1 and including the step of creating said field line means with electric field means.
Claim 15
Dependent Claim
53 words
A method of making an endless power transmission belt construction as set forth in claim 11 wherein said step of creating said field line means with magnet means comprises the steps of providing said magnet means in sleeve form, and disposing said magnet means sleeve and said belt sleeve in substantially concentric relation.
Claim 16
Dependent Claim
54 words
A method of making an endless power transmission belt construction as set forth in claim 14 wherein said step of creating said field line means with said magnet means includes the step of rotating said belt sleeve relative to said magnet means sleeve while the same are disposed in said substantially concentric relation thereof.
