    摘要： A system and method for measuring streaming potential, conductivity and permeability of a porous sample, such as a plug of fibrous material, in which a test electrolytic solution, such as a neutral dilute salt solution, is flowed through a flow cell containing the sample. The test solution, and a treatment solution whose effect on the sample is to be measured, are flowed through the flow cell as a series of liquid spurts. The system includes a plurality of solenoid valves which are controlled by a computer in accordance with a software program.

    摘要： A photostable UV absorbent with maximum absorption above 340 nm having the formula: ##STR1## wherein R is --CO(R.sub.2) or phenyl optionally substituted with lower alkyl and/or lower alkoxy; R.sub.2 is --alkyl, --O(C.sub.2+ alkyl), ##STR2## n has a value of from 2 to 8; S and T each independently are hydroxy, lower alkyl, lower alkoxy or, when R.sub.2 is alkyl or alkoxy, S can also be phenyl and when R.sub.2 is alkoxy, T is alkoxy, or S+T taken with the phenyl ring form a naphthyl radical or a fused benzodioxol-5-yl heterocyclic radical; k+l has a value of from 0 to 3 with the proviso that, when R.sub.2 is --O(alkyl), T is --O(lower alkyl) and the value of l is 2 or 3; R.sub.3 is hydrogen or lower alkylene; R.sub.4, R.sub.5, and R.sub.6 are each independently C.sub.1 to C.sub.18 alkyl or one of R.sub.4, R.sub.5 and R.sub.6 can be phenyl and A is an anion.
