Abstract: A waterproof-sheet type of roofing shingle comprises a belt-like tape attached to a bottom side of the roofing shingle facing a concrete slab. The belt-like tape has air passages for reducing a pressure of steam or vapor generated from concrete. The air passages are formed by projections or grooves and adapted to be in communication with air passages of an adjacent roofing shingle. The air passages are eventually in communication with an ambient atmosphere so as to vent the steam or vapor to the atmosphere, and therefore, bulging of waterproofing material is prevented from occurring.

Abstract: In a BAYER circuit, a process for controlling precipitation in which particle size quality of alumina hydrate produced in the circuit and circulating in feed tanks is monitored utilizing a calibration step and a control step. In the calibration step, cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer than X2 ?m, defined as CPFT X2, is measured vs. time and cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer that X1 ?m, defined as CPFT X1 vs. time, is measured, where X1 and X2 are predetermined particles sizes and X1 is smaller than X2. A relationship R between CPFT X1 and later changes in CPFT X2, is determined and upper and lower trigger thresholds of CPFT X1 which correspond to maximum permissible variation in CPFT X2 are defined. In the control step, CPFT X1 and CPFT X2 are regularly measured, and R and the correlation between CPFT X2 and the particle size of hydrate produced are updated.
