Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
A system for weighing material having particles which tend to stick together comprising: means for weighing, a first means for conveying material to said means for weighing, second means including a conveyor belt for conveying material to said means for weighing, vibratable means disposed transverse to the direction of movement of said conveyor belt to physically contact said material to provide frictional forces for separating the fibers of said material to permit fine weighing of said material.
Claim 2
Independent Claim
77 words
A system for weighing material having particles which tend to stick together comprising: means for weighing, a first means for conveying material to said means for weighing, second means including a conveyor belt for conveying material to said means for weighing, vibratable means disposed transverse to the direction of movement of said conveyor belt to physically contact said material to provide frictional forces for separating the fibers of said material to permit fine weighing of said material.
Claim 3
Dependent Claim
41 words
The invention as set forth in claim 1 wherein said first means for conveying material comprises another movable conveyor belt having means associated therewith to permit material thereon to be subdivided into predetermined amounts for delivery to said means for weighing.
Claim 4
Dependent Claim
49 words
