Patent ES-8303848-A1 (ES)
Title: Improvements in circuit arrangements for modifying dynamic range
IPC: H03G9/02
Filed: 1981-12-29
Abstract: The susceptibility of compressors, expanders and noise reduction circuits to undue control by signals outside the passband(s) in which the circuits are active is reduced. In a compressor which operates by narrowing the pass-band of a variable filter 22, the conventional feedback control via rectifier 31 and smoothing means 31, 32a, 32b is counteracted by a further signal derived from a wider frequency region by a rectifier 31' and smoothing circuit 32a'. The further signal bucks the main control signal in combining circuit 33. Similar arrangements are disclosed for arrangements using variable gain circuits instead of a variable filter and alternative arrangements use multichannel control signal circuits having limiters with different thresholds whereby the control signal is tailored to achieve like results. All arrangements reduce the circuit response to signal components outside the pass band(s) at high input signal levels.

Patent ES-8305282-A1 (ES)
Title: Process and installation for the biological purification of waste water.
IPC: C02F3/12
Filed: 1982-08-11
Abstract: This invention relates to a process for the biological purification of wastewater in at least two immediately successive treatment stages, followed by a post clarification stage wherein the process is adapted so that a wastewater-activated sludge mixture in one of the treatment zones exhibits only a minor biological load and a nitrification process is conducted therein. In accordance with the invention, an intermediate clarification tank is not required due to substantially all biological degradation having occurred in the stage immediately before the nitrification stage. To enhance nitrification a macroporous carrier material for supporting nitrifying bacteria, for example, activated carbon or polyurethane foam, is added into this nitrification treatment stage. The material can be readily retained in the nitrification zone by providing appropriate retaining means. This process offers the advantage that the concentration of nitrifying agents, i.e., bacteria necessary for nitrification is maintained at the required level at all times. In another aspect, the invention relates to the apparatus for carrying out the process.
