Between the driven shaft of the electric servomotor (86) and the transmission (35) a planetary gear (87) is connected.

Abstract: The apparatus makes it possible to change a desired sample volume—even during operation—in a simple manner without mechanical intervention, with any accumulation solids of a sample contained in a sample collecting vessel being avoided, so that a sample representative of the medium is obtained. The apparatus comprises a control unit which controls a pneumatic control gear and switches a pump by means of which the medium is drawn into a sample collecting vessel via a hose or tube used as a suction line. A detection unit incorporated in the suction line signals the presence of the medium to the control unit, which then controls the time period for taking the desired volume of the sample. The sample volume obtained is drained off into a sample container via a drain device.

Abstract: A mounting unit includes a mounting part having an activation side defining an opening leading to a throughbore. A fixing part is insertable into the throughbore is fastenable to the mounting part, the fixing part including: a head which allows a fastening of the fixing part to the mounting part; a shaft adjoining the head on a top end thereof and being insertable with its bottom portion and with radial play into the throughbore; fixing projections disposed at the bottom portion of the shaft and extending beyond a cross section of the shaft in a plane perpendicular to the shaft longitudinal axis, the fixing projections being effective over an entire circumference of the shaft for fastening the fixing part to the mounting part; and an undercutting space disposed between the head and the fixing projections. A holding sleeve is adapted to be fastened to the mounting part and to surround the shaft and the fixing projections with radial play after the fixing part is inserted into the mounting part.

Abstract: In a method for making an assembly unit from an assembly bolt (3) that has a bolt head (9) and a shaft (6) and from a sleeve that has an axially movable annular collar (11) toward the head that surrounds a partial axial region of the shaft, first the shaft that has a counterpart back-engagement part is introduced into the sleeve, and then at least one back-engagement part on the sleeve is created by means of a stamping oriented essentially inward from the outer jacket face. The stamping has an action that is oriented radially inward and an action oriented toward the bolt head (9). In the stamping, a counterholder presses against the bearing face (22) of the annular collar (11) oriented toward the bolt head (9).

Abstract: In a water treatment process using ozone, to prevent bromate formation a quantity of bromide-containing water for treatment is first set to a pH value of less than 6.5 by feeding in CO.sub.2, unless the water already contains the requisite CO.sub.2 by origin. CO.sub.2 and ozone are then simultaneously fed in for a period of several minutes. The feed stream of CO.sub.2 is designed to maintain the pH value, and sufficient ozone is fed to the quantity of water to produce oxidation and sterilization.

After actuation by the brake by hydraulic piston, the saddle is returned to its rest position by a compression spring. A friction element is provided between the sliding bolt in the bore for limiting the travel of the saddle in response to the bias of the spring. The friction element exerts a force greater than the bias of the spring but less than that exerted by the brake actuator, such that the brake is self-adjusting for lining wear. The brake is disclosed in plural embodiments.
