A cascadeable integrator (80) for use in a digital filter comprises a first layer (LAYER1) for receiving a first sequence of parallel input signals (86, 88). At least one subsequent layer (LAYER2) is provided, the subsequent layer (LAYER2) being connected to the first layer (LAYER1) for generating a second sequence of parallel output signals (82, 84), wherein each of the parallel output signals (8...

The control method is for a series compensated converter station which comprises a converter (SR2) controlled by control equipment (CE2) and connected to a three-phase alternating network (N2). The control equipment generates an ordered value (AOL) of a control angle (~a) for valves (V1-V6) included in the converter depending on a limiting value (AMAXL). A calculating value (AMARG) of a control an...

An improvement of the electrostatic filters with Volta-effect, for first-class conductors, for the deionization of the ashes of cigarettes and similar, wherein said improvement simplifies, at industrial level, the realization of said electrostatic filters with Volta-effect and eliminates the actual use of the so-called cellulose silkworm used for the realization of the cigarette filters. The impro...
