Abstract: The invention relates to any procedure and equipment, where laminated, soft magnetic mass is used in a direct and/or indirect form for the production of magnetic fields. For instance applying in inverters, converters, transverters and transformers in such a way, through that we transfer voltage and/or current from the primary side onto the secondary side—with use of a magnetic field. With application of this procedure and interconnected technique, an opportunity presents itself for reduction of both the quantity and the measures of iron mass of laminated transformers to their quarter size, which transformers are applied in electric facilities with operation of low frequency, however independently from the functional frequency and the power of the equipment. The equipment is able to provide much larger starting current and is not sensitive to any spasmodic load either. Thus, it is not necessary to apply expensive semiconductors of high frequency as well as costly technologies.

Abstract: Performance and equipment for the improvement of performance of (15) wind and/or water machines, with an (5) additional pneumatic system, with utilization of kinetic energy arisen by (16) wind and/or water, with use of (8) the produced and compressed air stored in the (9) supporting column and/or in (11,13) external containers, thereby it increases the efficiency factor. This procedure and equipment possess that feature that all of the units are settled onto the same (12) crankshaft connected through several electronically controlled clutches and/or (2a,b) Hardy-disks to an (5) air compressing pneumatic compressor, a (1) voltage inducing generator and a (7) double-functional motor-generator (7), that of which functions at the same time as a starting-engine.
