Patent DE-3641138-C1 (DE)
Title: Pipe compensator, particularly a compensator bridge
Inventor: SCHMIDT RAINER DIPL-ING
IPC: F16L27/08
Filed: 1986-12-02
Granted: 1987-12-03
Abstract: Cardan compensators, which are mobile in all directions in a circular plane, are known. The axis of rotation lies in the plane of the centre of the bellows. This compensator does not accept changes in length. The new compensator bridge is intended to transmit torsional moments of the tubes. The bridge for a compensator (1), the said bridge being fastened to a bracket (3), has two straps (4) on one side which transmit the transverse force via a cross-pin (6) and a sliding block (7) to a strap (5) attached on the other side. The bridge is suitable, in particular, for applications where axial movements have additionally to be accepted by the compensator in addition to the transmission of torsional moments. <IMAGE>

Title: Control stage for a radio-frequency power amplifier
Inventor: KHILLA ABDEL-MESSIAH DR-ING
IPC: H03G3/20
Filed: 1987-12-12
Granted: 1989-02-23
Abstract: In a control stage for a radio-frequency power amplifier (TW) preceded by a preequalizer (VZ) for compensating for nonlinearities, a preamplifier (VV) is provided. This preamplifier (VV) exhibits at its input an adjustable attenuator (ED1) and at its output a sensor (MF). The sensor (MF) is used for detecting the output level of the preamplifier (VV) or the current consumption of the amplifier elements and supplying them to a control device (KE). A control device (KE) is used for setting the attenuator (ED1) in such a manner that a threshold value which corresponds to a certain gain in the linear gain range of the preamplifier (VV) is not exceeded. Due to this measure, the preamplifier (VV) operates in the strictly linear range and cannot generate any additional intermodulation (Fig. 1). <IMAGE>

Title: Regenerative SO2 flue gas purification
IPC: C01B17/76
Filed: 1988-09-07
Granted: 1989-12-07
Abstract: In the so-called regenerative methods for flue gas purification, the absorbent Mg is regenerated from the sulphite separated off and SO2 liberated again is further processed to give sulphur or a sulphur compound. In addition to sulphite, sulphate is also always produced in this process which can only be further processed together with the sulphite at great expense. The invention is to prevent enrichment of sulphate at lower expense. From a main scrubbing stage, a sulphate solution is isolated, brought into contact with a lime-containing scrubbing liquid of a prescrubbing stage and a gypsum formed is removed.
