Abstract: Voltage stabiliser for electrical energy transportation and distribution applications, which consists of one or several electromagnetic devices of transformer type which, at discrete intervals, regulates the output voltage that reaches the consumer, taking the form of a transformer with a dual or quadruple primary winding and a simple secondary winding, the simple winding being able to be positioned before or after the parallel branch, the performance of the equipment remaining the same.

Abstract: A heat pump system based on the Peltier effect, built around a transparent or translucent material element and formed by two sheets (1) in which chains of thermoelements (3, 4) are embedded, trapped or inserted, said thermoelements being connected along their respective alternate ends with the aid of parts (2) made of a material with good thermal and electric conductivity properties, which chains are liable of being supplied with external electric energy so that heat transport is based on the direction of the current flowing through said thermoelements.
