This principle established, the following are the details of the ingenious apparatus of Sandford andVarralL R, as we have said, is the regulating wheel, provided with scoops eee; this wheel is confined in adrum B, which the pulp enters from the reservoirs A A by the large stop-cocks r r, kept entirely open,so as to maintain sensibly in the drum B the same level as in the reservoirs A A. It is of little im-portance, moreover, if this level be not rigorously equal, nor even if it varies notably in the reservoirsA A; for, provided the pulp arrives in sufficient quantity, and we must take care that it be always so,each of the scoops, every time they issue from the pulp, only withdraws the same quantity of material. 3008.
