Abstract: A method and apparatus are described for removing pollutants from sub-soil formations in the ground, ground water being pumped out over an extended period of time to remove, in particular, highly volatile halogenated hydrocarbons, whereby the pollutants are entrained and the ground water is purified at the surface (10) by separation of the pollutants (stripping). In order also to remove pollutants of relatively high density and pollutants which are sparingly soluble in water without problem from soil formations replenished with water, it is proposed that the water-replenished soil area to be purified is subjected to acoustic treatment with a sound transducer (5). The sound transducer (5) in this case comprises two plate-shaped elements of membrane (14) type, between which is disposed a coil (13). <IMAGE>

Abstract: In the press section of a paper making machine, there is a central roll, a first press roll beneath and a second press roll above the central roll defining respective first and second press nips. The first press nip or both nips may be extended nip presses. A water impervious press belt travels through the first press nip around the central roll and through the second press nip, meeting the central roll before the first nip and leaving the central roll after the second nip. A felt belt conducts the web to be dewatered into the first nip along with the press belt. The felt belt separates from the web after the first nip. Following the second press nip, the press belt carries the web to a place of removal where a dryer wire picks up the web. The distance from the second press nip to the place of removal is at least equal to the circumference of and is preferably greater than the circumference of the central roll. The path of the press belt from the second nip to the removal place may be bent by a deflection roll.

Abstract: The output shaft (12) of a driving device for a windscreen wiper system on a motor vehicle is driven in pendulum fashion by an electric motor (1) via a gear known per se. The angle between the two pendulum limit positions can be up to 180 DEG . The two rotation limit positions are fixed by a stop element (21) on a stop component (19) and two stops (22, 23) fixed to the housing. In order to avoid running on and in order to achieve a gentle striking against the stop (21), a cam (36) which is offset radially with respect to the geometric axis (38) of the output shaft (12) and protrudes axially towards a cover (32) or the like is attached to the stop component (19). Said cam cooperates alternately with two arcuate ramps (30, 31) on the inside of the cover which rise with a gentle slope. Starting from a central position, the friction between the cam (36) and the abutting ramp surface becomes increasingly large and the swing of the wiper arm is reduced as the angle of rotation increases. This also prevents a sudden striking of the stop element (21) against the stop (22 or 23) and an associated generation of noise. In addition, in this way the two limit positions can also be correctly maintained even in the case of an extreme wiper angle. <IMAGE>
