Regeneratoren und Sorptiv-Regeneratoren
Forschung auf dem Gebiete des Ingenieurwesens, 1962Die lineare Naherungslosung der Regeneratorengleichungen wird durch einen Gutegrad-Ansatz vervollstandigt, was eine elementare Berechnung gewohnlicher Regeneratoren sowie die praktische Auslegung von nassen Regeneratoren und Sorptiv-Regeneratoren ermoglicht. Es ergeben sich nutzliche Kriterien fur den zweckmasigen Betrieb, z. B.

A variable sorptivity infiltration equation
Water Resources Management, 1989Horizontal and vertical one-dimensional infiltration are compared when they both occur in a homogeneous isotropic porous body initially at a uniform low water content θn under constant concentration (θ0) or constant pressure head (H0) conditions. From a consideration of the physics governing infiltration under such conditions, the conclusion is reached

High capacity headspace sorptive extraction
Journal of Microcolumn Separations, 2000A new approach for sorptive enrichment of analytes from the headspace of aqueous or solid samples, referred to as headspace sorptive extraction (HSSE) is described. The technique implies the sorption of volatile and semivolatile compounds into a large amount of polydimethylsiloxane (ca. 50 mg) placed on a glass rod support.

In situ measurement of sorptivity
Australian Journal of Soil Research, 1969Measurements of sorptivity are reported for a number of field soils. The main method, used in situ, is simple and consists of timing initial vertical flow of water into an undisturbed soil profile. This method relies on the assumption that, during the measurement time of 1-2 min, the first term of the infiltration equation i = St1/2 + At + Bt3/2 ...

Sorptive properties of glasslike polymers
Journal of Polymer Science, 1957AbstractThe swelling and solution of elastic polymers, like the mixing of liquids, results in the formation of equilibrium systems. In the interaction of conventional glasses and liquids, however, quite different phenomena appear and cause nonequilibrium systems to form.
