Patent DE-3347385-A1 (DE)
Title: Process for the treatment of metal-containing effluent
Inventor: JENTNER LUDWIG
IPC: C02F9/00
Filed: 1983-12-29
Abstract: The treatment of metal-containing effluent meets difficulties in particular when the metals are present in different oxidation states and/or are strongly complexed. The hitherto conventional precipitation using sulphides or sulphide derivatives not only leads to toxic products, but also to a high salt load. The invention describes a process for the treatment of such effluent, which, at a high purification efficiency, avoids these disadvantages. This is possible by the addition of easily oxidisable reducible metal salts (metal salt compounds) or corresponding metals which comply with the following requirements:   a) the reagent, on the basis of its redox potential, must act as a reducing agent for the metals to be precipitated, b) it must give a positive potential (dG>0) together with the metals contained in the effluent as redox partner, c) after carrying out the reduction, it must precipitate as a poorly soluble metal hydroxide.

Title: Converter arrangement for phase-coupled carrier frequency transmission systems
Inventor: SCHOLZ GUENTHER
IPC: H03D7/16
Filed: 1984-02-09
Abstract: A converter arrangement which is suitable for phase-coupled carrier frequency transmission systems, and has an input converter for converting an input channel into a predefined intermediate frequency channel, and an output converter for converting the intermediate frequency channel into a selectable output channel, is proposed. The input and output converters each contain a PLL oscillator circuit. In the PLL oscillator circuit of the output converter (14), a phase comparison takes place between a reference frequency (fR), which is derived from a reference frequency (fB) via a first frequency divider (29), and a standard frequency (fV), which is derived via a second frequency divider (31). The frequency (fS) of an interrupting channel is chosen as the reference frequency (fB). Also, the division ratio (1/Y) of the first frequency divider (29) of the output converter is chosen so that the reference frequency derived from the frequency of the interrupting channel is equal to a predefined frequency shift ( DELTA f). The division ratio (1/q) of the second frequency divider (31) is chosen so that the standard frequency (fV) which it supplies is equal to the reference frequency (fR). <IMAGE>
