专利汇可以提供Measuring water drainage rate from wet stock fourdrinier screen using radiation source and detectors专利检索,专利查询,专利分析的服务。并且In a Fourdrinier papermaking machine, the variation in the mass of the slurry along the length of the Fourdrinier travelling forming screen and the rate of water drainage therethrough are determined by a radioactive wire threaded along the length of the screen, or a plurality of radioactive sources successively disposed therealong, in conjunction with either a single radiation detector moved synchronously with the screen or a plurality of detectors monitored continuously or scanned synchronously with the screen movement.,下面是Measuring water drainage rate from wet stock fourdrinier screen using radiation source and detectors专利的具体信息内容。

1. In a papermaking machine of the type having a traveling forming screen which receives and carries wet stock in the downstream direction and through which water is drained along its stock carrying length, the improvement comprising: radiation source means and associated detector means disposed adjacent said stock as it is carried by said screen for measuring the stock mass along the said screen length, and means responsive to said detector means for determining the water drainage rate through the screen along its said length.
2. Apparatus as in claim 1 wherein said detector means provides a plurality of outputs at spaced points along said screen length and said drainage rate determining means monitors said outputs continuously.
3. Apparatus as in claim 1 wherein said detector means provides a plurality of outputs at spaced points along said screen length and said drainage rate determining means scans said outputs serially.
4. Apparatus as in claim 3 wherein said determining means scans said outputs synchronously with the travel speed of said forming screen.
5. Apparatus as in claim 1 wherein said radiation detector means comprises a detector which is movable in said downstream direction at a speed synchronized with the travel speed of said forming screen.
6. Apparatus as in claim 1 wherein said radiation detector means comprises a plurality of radiation detectors disposed at spaced points along the said length of said screen.
7. Apparatus as in claim 6 wherein said radiation source means comprises a plurality of radiation sources disposed at said spaced points along the said screen length respectively for said detectors, the sources being located on one side of the wire and the detectors on the other.
8. Apparatus as in claim 7 wherein said drainage rate determining means includes means for continuously monitoring each detector output.
9. Apparatus as in claim 7 wherein said drainage rate determining means includes means for scanning the detector outputs serially.
10. Apparatus as in claim 1 wherein said radiation source means comprises a radioactive wire threadedly extending in said forming screen along the said length thereof.
11. Apparatus as in claim 10 wherein said radiation detector means comprises a single detector which is movable in said downstream direction at a speed synchronized with the travel speed of said forming screen.
12. Apparatus as in claim 10 wherein said detector means comprises a plurality of radiation detectors disposed at spaced points along said wire length.
13. Apparatus as in claim 12 wherein said drainage rate determining means includes means for scanning the detector outputs synchronously with the travel speed of said forming screen.
14. Apparatus as in claim 1 wherein said radiation source and detector means are disposed so as to be on opposite sides of the said wet stock as it is carried downstream by said screen.
15. A method for determining the water drainage rate from wet stock on a travelling forming screen in a papermaking machine comprising the steps of detecting with a radiation source and associated detector means, the weight per unit area of said stock as it travels with said forming screen, and using the weight per unit area resulting therefrom at least at successive points in said travel to indicate the rate of water drainage through said screen.
