Abstract: Inside the casing (1), there are three or more ribs (8) arranged with their longitudinal axes parallel to the closing body's direction of movement when closing so that each rib forms a slide-way for the closing body (5) moving from open into closed position. Into each of these ribs there is cut a first groove (10) in which is placed a shaped part (11) that supports the closing spring (9). At least the ribs arranged approximately opposite to the tappet (20) have a second groove whose side facing the seat (7) forms a rest edge (18) on which the control edge may rest when the closing body is in open position. When the fusible soft solder component (21) is melting away, the tappet changes its position in axial direction under the force exercised by the closing spring. Due to this change of position, the control edge is no longer resting on the rest edge, and the closing body driven by the dosing spring switches over into its close position.

Patent KR-20010052484-A (KR)
IPC: C02F3/34
Filed: 1999-05-31
Abstract: A process is disclosed for regulating the aeration in a biological wastewater treatment plant using a carbon removal stage, a nitrification stage and a denitrification stage. The process includes the step of continuously measuring the value of oxidation-reduction potential of the treated medium as well as measuring oxygen concentration of the treated medium during aeration phases. This permits maintaining aeration if the oxygen concentration falls within a preselected reference range. Alternately there is reduction of the aeration if the oxygen concentration is above the preselected reference range, or increasing the aeration if the oxygen concentration falls below the preselected reference range. The process requires comparing the oxygen concentration in the treated medium with the preselected reference range during a transition of the oxidation-reduction potential (partial nitrification/total nitrification); and adjusting the reference range of oxygen concentration to a new set of values to correct the oxygen concentration toward a preselected desired level.
