AN IMPROVED BALANCING UNIT FOR USE WITH RADIATION GAUGES
Patent
·
OSTI ID:4150563
A description is given of an adjustable balancing unit for use with a radiation gage for the measurement of the mass of a moving material, e.g., a moving tobacco filler in a continuous-rod cigarette-making machine. The unit is similar to the gage, but it has an absorber between its radioactive source and detector equivalent to the desired mass of the moving material; the currents from the unit and gage oppose each other and thus variations in the moving material may be measured. The absorber comprises a pair of eccentric rotatable metal disks with edges touching in front of the detector window; by suitable rotation of the disks, the absorption value of the unit can be varied.
