Patent DE-19813100-A1 (DE)
Inventor: HEPKE HANS-JOERG
IPC: C02F11/12
Filed: 1998-03-25
Abstract: In a sewage sludge drying and sterilization process, a dilute supply of incoming (1) sludge is mechanically de-watered (2) and released into a holding tank (3). It is then pumped (4) into a heated (6) cascade drier (5) with a series of helical conveyers (5a, 5b, 5c). The cascade operates under conditions of reduced pressure. Moisture arising from the cascade drier is surrendered through a pipe (7a) to a vapor washer (7) from which water is returned (7a), while air is piped (7d) to a filter (8). Sludge enters the cascade drier (5) as a paste and leaves (9) at the bottom in dry condition.

Inventor: TENTEN WILFRIED
IPC: H03K3/354
Filed: 1998-12-10
Abstract: The invention relates to a reduced harmonic distortion oscillator circuit comprising an adjustable oscillator amplifier (3) for generating an oscillator output signal and an amplitude regulating circuit (2) for regulating an amplitude A of the oscillator output signal, wherein the amplitude regulating circuit (2) generates an amplitude regulating signal Vregel depending on a detected amplitude A of the oscillator output signal in such a way that the oscillator amplifier (3) operates in a given operative range with almost linear amplification characteristics and a definable lower amplitude in a determined operating point. The oscillator amplifier (3) is configured in such a way that the given operative range and operating point are independent from the amplitude regulating signal Vregel. A stable amplitude regulation loop can thus be realized for generating a reduced harmonic distortion oscillator output signal even when the properties and parameters of the components used exhibit a larger scattering area. The oscillator circuit can be easily embodied as an integrated circuit.
