Abstract
Abstract An apparatus for monitoring the mass or weight of consecutive individual containers moving on a conveyor unit including radiation means spaced from a conveyor unit for subjecting filled containers to a field of nuclear radiation. Suitable detection means detect the amount of radiation not absorbed by the filled containers and correlate this with the fill weight which is then translated to an electrical signal and fed to suitable recording means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A method of monitoring the average weight of a stream of consecutive individually contained portions of material comprising arranging a fixed volume of a stream of filled containers with said containers being spaced from each other by lead blocks on a conveyor unit, passing said stream of filled containers spaced by lead blocks through a field of nuclear radiation emanating from a source of radiation spaced from said stream in a plane parallel thereto with one end of said source being advanced in the direction of movement of said stream with respect to the other end of said source in an amount sufficient to traverse at least one filled container, said predetermined fixed volume of said stream being a fixed volume of at least one filled container, detecting the amount of radiation absorbed by each successive container by measuring the amount of radiation not absorbed by each successive container, translating said measured amount of radiation to an electrical signal, and then monitoring said electrical signal on recording means.
Claim 2
Independent Claim
168 words
A method of monitoring the average weight of a stream of consecutive individually contained portions of material comprising arranging a fixed volume of a stream of filled containers with said containers being spaced from each other by lead blocks on a conveyor unit, passing said stream of filled containers spaced by lead blocks through a field of nuclear radiation emanating from a source of radiation spaced from said stream in a plane parallel thereto with one end of said source being advanced in the direction of movement of said stream with respect to the other end of said source in an amount sufficient to traverse at least one filled container, said predetermined fixed volume of said stream being a fixed volume of at least one filled container, detecting the amount of radiation absorbed by each successive container by measuring the amount of radiation not absorbed by each successive container, translating said measured amount of radiation to an electrical signal, and then monitoring said electrical signal on recording means.
Claim 3
Dependent Claim
33 words
A method according to claim 1, which includes separating said consecutive containers by blocks of solid Material and wherein the centerline of said source traverses one and one half containers plus a block.
Claim 4
Dependent Claim
65 words
A method according to claim 1, wherein said source of radiation is an elongated strip source spaced from said stream of filled containers spaced by lead blocks and at an acute angle thereto so that the centerline of said source of radiation is the diagonal of a rectangle formed by at least one filled container plus at least one lead block adjacent said filled container.
Claim 5
Dependent Claim
47 words
A method according to claim 1, wherein said source of radiation is a rectangular plate source spaced from said stream, said plate subjecting an entire surface of at least one filled container and at least one block adjacent said filled container to a field of nuclear radiation.
Claim 6
Dependent Claim
49 words
A method according to claim 1, wherein said source of radiation is a horizontal elongated strip source spaced far enough from said stream for subjecting an entire surface of at least one filled container and at least one block adjacent said filled container to a field of nuclear radiation.
