Abstract
Abstract An apparatus for measuring the quantity of asphalt ingredient in an asphalt compound in an apparatus for mixing asphalt ingredient and an aggregate to form the asphalt compound including a neutronic line which reacts with a hydrogen atom of the asphalt ingredient in such a manner as to decrease the energy in the neutronic line so as to detect the quantity of asphalt ingredient in the asphalt compound, a continuous conveying means for supplying asphalt compound to the neutronic line and a means responsive to the neutronic line for automatically adjusting the amount of asphalt ingredient in the asphalt compound whereby the amount of asphalt ingredient in the asphalt compound is maintained at a standard value.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
An apparatus for measuring the quantity of asphalt ingredient in an asphalt compound in an apparatus for mixing asphalt ingredient and an aggregate to form the asphalt compound comprising: a container; a means for radiating a neutronic line provided within the container which reacts with a hydrogen atom of said asphalt ingredient in such a manner as to decrease the energy of the neutronic line; a detector provided in said container adjacent said radiating means for detecting changes in the energy of said neutronic line; a continuous conveying means for continuously supplying asphalt compound into said container; and a means responsive to the detector for automatically adjusting the amount of asphalt ingredient in said asphalt compound whereby the amount of asphalt ingredient in said asphalt compound is maintained at a standard value.
Claim 2
Independent Claim
132 words
An apparatus for measuring the quantity of asphalt ingredient in an asphalt compound in an apparatus for mixing asphalt ingredient and an aggregate to form the asphalt compound comprising: a container; a means for radiating a neutronic line provided within the container which reacts with a hydrogen atom of said asphalt ingredient in such a manner as to decrease the energy of the neutronic line; a detector provided in said container adjacent said radiating means for detecting changes in the energy of said neutronic line; a continuous conveying means for continuously supplying asphalt compound into said container; and a means responsive to the detector for automatically adjusting the amount of asphalt ingredient in said asphalt compound whereby the amount of asphalt ingredient in said asphalt compound is maintained at a standard value.
Claim 3
Independent Claim
110 words
An apparatus for measuring the quantity of asphalt ingredient contained in an asphalt compound composed of an asphalt and a material, comprising a hopper wherein the asphalt compound flows down vertically at a fixed speed, a penetrating protective pipe extending through a side wall of said hopper, a removable moving pipe provided in said protective pipe, a neutronic line source provided in said removable moving pipe for radiating a neutronic line in the conveyed asphalt compound, a detector provided in said movable moving pipe for detecting a decrease in the energy of the neutronic line caused by reaction with the asphalt and a shifting means for shifting the moving pipe.
Claim 4
Independent Claim
110 words
An apparatus for measuring the quantity of asphalt ingredient contained in an asphalt compound composed of an asphalt and a material, comprising a hopper wherein the asphalt compound flows down vertically at a fixed speed, a penetrating protective pipe extending through a side wall of said hopper, a removable moving pipe provided in said protective pipe, a neutronic line source provided in said removable moving pipe for radiating a neutronic line in the conveyed asphalt compound, a detector provided in said movable moving pipe for detecting a decrease in the energy of the neutronic line caused by reaction with the asphalt and a shifting means for shifting the moving pipe.
