Abstract: The invention features a nonwoven composite material which includes a layer of staple fiber aligned surface-to-surface with a spunbonded continuous filament web layer, the layers being continuously thermally bonded.

Abstract: The invention concerns an immunological detection process, with which triazines and structurally similar compounds and/or biologically equivalent compounds with similar bonding behavior are detected as belonging to one activity class, but with which on the other hand it is possible to identify the individual substances even in complicated mixtures.

Abstract: The magnetic valve with electronic control for increasing the attractive output has an energizing coil (AE), which is supplied in the attracting phase with an increased energizing current via a closed switch (T2). In the maintenance phase, the energizing coil (AE) is supplied with a maintenance current, via a compensating resistor (RV) and with the switch (T2) opened, which is lower than the energizing current. For the purpose of controlling the switch (T2), a timing circuit is provided which includes a resistor (R2) and a capacitor (C2). The magnetic valve is selectively drivable with alternating current or direct current. A portion of the energizing coil (AE) is made up of the compensating resistor (RV), which is embodied as a resistor wire and wound up on the energizing coil (AE).
