Abstract: Abwasser, das schwer abbaubare organische Verunreinigungen enthält, wird durch Oxidation in waßriger Phase bei Temperaturen von 100 bis 310 °C und unter erhohtem Druck gereinigt. Hierzu wird zunachst in einer ersten Stufe (8) das Abwasser ohne Zusatz von Katalysatoren mit sauerstoffhaltigen Gasen so lange behandelt, bis der CSB-Wert um 50 bis 98% verringert ist. Anschließend wird das so vorgereinigte Abwasser bei gleicher oder höherer Temperatur in einer zweiten Stufe (10) in flüssiger Phase mit einem stärkeren Oxidationsmittel als Sauerstoff behandelt, bis der CSB-Wert auf nahezu 0 g/l abgesunken ist.

Abstract: A viscous fan clutch (10) is typically employed in a fan drive mechanism within a truck or automobile. A shaft (12) driven by the engine, rotates a clutch member (24) within the fan drive. The clutch member is arranged for fluid engagement with a cover assembly (38) for the transmission of torque thereto when the fluid is disposed in an operating chamber (70) defined by complementary shear surfaces (30, 31, 56, and 57) in the clutch and cover. During relative rotation between the clutch and cover, fluid is pumped from the operating chamber to primary (76) and secondary (77) fluid storage chambers. Independent fluid temperature responsive control valves (120 and 190) provide for selective communication between the storage chambers and the operating chamber to effect modulation of the total fluid flow whereby dual speed operation of the clutch is achieved. In the preferred embodiment, one of the valves operates in response to impinging ambient air at a relatively low temperature and the other valve operates in response to sensed engine coolant temperature at a relatively high temperature.

Abstract: An expanding fastening element joins two structural members such as two pieces of girder of which one has a slot with lips at the sides thereof, so that the two members may be separated again when desired. The expanding fastening element includes two legs that are hinged together and may be opened out by way of a fixing screw into a locking or gripping position with hook-like heads of the legs hooked onto the lips. Before tightening the screw the fastening element is positioned at the desired position in a hole in one girder by a guide sleeve or plug locking into the second member and springingly pushed outwards from the fastening element by a spring within it. The two legs or gripping members have keeper heads and slots at their ends opposite to the hooked heads to take up a c-like ring spring. The threaded plug is pushed by at least one spring against the second of the two legs, in which the plug is taken up in a guide opening so that it may be pushed by the spring into an opening branching off from the hole (in the second member) into which the fastening element has been placed, the screw being in the plug. In a hollow in the face of the second leg there is a support part for the inner end of the fixing screw.

Abstract: In a process for recovering pure methylal from methanol-methylal mixtures, which can optionally contain still further compounds, the separation conducted in a rectification device comprising two rectifying columns. In the first rectifying column, the mixture to be separated is rectified under a pressure lower than that in the second column, into a methylal-rich, methanol-poor distillate, and into a practically methylal-free, methanol-rich sump product. The methylal-rich distillate of the first rectification is then separated in a second rectifying column, operated under a higher pressure than the first rectification column, into a compound stream containing methanol and methylal, which is then recycled to the first rectifying column, and into pure methylal as the sump product. In a specific refinement, the first rectification is preferably operated under a pressure of 1-22 bar absolute and the second rectification preferably under a pressure of 9-30 bar absolute, with the second rectification being operated under a pressure which is at least 8 bar higher than that of the first rectification.
