Title: Process for preventing the formation of CaSO4 deposits on the semipermeable membrane used in reverse osmosis
Inventor: VAJNA SANDOR DIPL ING CHEM DR
IPC: B01J41/07
Filed: 1986-02-06
Abstract: It is known that when reverse osmosis (RO) is employed to remove a large part of the salt content of untreated water, the used membrane is plugged after a certain time by depositing salts. The majority of the deposit is composed of CaSO4 which can no longer be dissolved in the solution concentrated by RO. In the present case, the formation of these salts is prevented by removing the sulphate ions from the as yet unconcentrated untreated water with the aid of a weakly basic specific anion exchanger, the Cl ions of which replace the SO4 ions.

Title: Arrangement for linearising a transmitter output stage
Inventor: ESPRESTER RALF
IPC: H03G3/20
Filed: 1986-11-29
Abstract: The main patent describes an arrangement for linearising a transmitter output stage, in which the signal envelope of the RF signal driving the output stage, and the signal envelope of the output signal of the output amplifier are detected and compared in a differentiating element and from the comparison a control signal is derived for a controllable attenuator arranged in the signal path of the RF signal in front of the output stage. This arrangement is simplified by the fact that a signal processor is provided which generates from the modulation signal, taking into consideration the selected type of modulation, an envelope curve reference signal which is compared with the measured envelope of the output stage output signal in the differentiating element. When the reference signal is generated, the setting of the level of the output stage output signal to the rated power of the output stage is already taken into consideration.

Title: Arrangement for supplying a main consumer with hydraulic pressure medium
Inventor: SCHOPF WALTER
IPC: F15B11/17
Filed: 1987-08-29
Abstract: An arrangement for supplying a main consumer with a hydraulic pressure medium is proposed, which contains a flow switch by means of which, starting from two common driven pumps delivering the pressure medium for the main consumer, the pressure-medium flow of one of the pumps, when the drive speed increases, can be switched out to a direct backflow of the delivered pressure medium to the pressure-medium supply in order to save energy. In this arrangement, when the pressure of the pressure medium continues to increase as a result of further increasing drive speed, either the pump which is not switched out can be additionally connected to a secondary consumer for power dividing or, starting from two pumps with different delivery capacity, the connection between the pump pressure sides and the main consumer on the one side and the pressure-medium supply on the other side can be interchanged.
