Patent ES-405005-A1 (ES)
Title: Weight-measuring unit
IPC: G01G13/04
Filed: 1972-07-20
Abstract: A two stage method of performing weighings of repeated dosages of granulated or powdered material in which the variations in "surplus" of the dosages are reduced by modulating, in dependence on the time taken by a "predosage" step, the rate of volume flow of the material to a weight sensing device during a second or "balance quantity" step, so as to obtain from one weighing operation to the next a substantially constant rate of flow of material by weight during the "balance quantity" step. A device for weighing repeated dosages is also described. This has a hopper adjacent the exit of which is mounted a rotatable metering drum for feeding material to a weight sensing device. A screen having an opening therein can be brought at the end of the "predosage" step into contact with the drum in order to reduce the rate of volume flow of material to the weight sensing device during the "balance quantity" step. A shutter can be adjusted relative to the screen to vary the size of the opening and is arranged to move with the screen. A cam is rotated from a start position at the beginning of each weighing operation and is stopped at the end of the "predosage" step. This cam controls the adjustment of the shutter relative to the screen and thus effects the desired modulation of the rate of flow of material by volume during the "balance quantity" step.

Title: Method and apparatus for monitoring the output of a neutron detector
IPC: G01T3/00
Filed: 1978-01-26
Abstract: PURPOSE: To detect leakage of gas correctly by producing an AC signal proportional to the means square AC signal in an ionization box and a DC signal proportional to DC current and determining the ratio thereof, and then repeating the operation after variation of gas density and correcting the output. CONSTITUTION: Output at the terminal 22 of a power supply/signal regulation circuit 19 is VMSV which is proportional to a mean square AC current flowing through the ionization box of a detector 1. Output at the terminal 23 is VDC which is proportional to a DC current flowing through the ionization box. An arithmetic circuit 29 receives AC and DC signals and determines the ratio R between them. The ratio R' between AC and DC signals after variation of gas density is then determined and a signal VDC' proportional to a DC appearing in the ionization box after variation of gas density is produced. Finally, the VDC is corrected according to an equation: VDC=(R/R')VDC'.
