Abstract: A method for providing a coated strip, which includes the steps of providing a metal or metal alloy strip, applying one or more coating layers on the metal or metal alloy strip and irradiating one or more of the applied coating layers with electromagnetic radiation, wherein one or more of the applied coating layers includes dielectric particles capable of absorbing microwave radiation and wherein microwave radiation is used to selectively heat one or more of the coating layers containing the dielectric particles to dry and/or cure and/or sinter the coating layer.

Abstract: This relates to a heating device including a solar energy collector, the solar energy collector transferring collected solar energy to outside air. First collector panels are used to heat outside air which heated air is led to a heater, for example a space heater. Second collector panels are used to transfer solar energy to air led to a heat exchanger of a heat pump. The heat pump transfers the extracted heat to heat storage. The stored heat is added to the air coming from the first collector panels if the temperature of the air coming from the first collector panels is below a predetermined temperature.

Abstract: A method of producing a coated grain oriented steel strip, which includes the steps of: forming an insulating layer on the grain oriented steel strip; providing a chromium-free coating mixture that comprises a metal phosphate silica particles and an organosilane; applying the mixture on the insulating layer; and curing the mixture to form a chromium-free coating that provides tension to the grain oriented steel strip.

Abstract: An arrangement for generating electricity including thermoelectric generators, the generators converting a heat difference between a first and a second surface of a generator in electricity, elements to provide a heated first medium to the first surfaces of the one or more thermoelectric generators and elements to provide a second medium with a temperature lower than that of the first medium to the second surfaces of the one or more thermoelectric generators. The first medium is heated by solar energy collector elements, which solar energy collector elements transfer collected solar energy to air passing through the solar energy collector elements. The first medium is a working fluid or the heated air itself. The second medium is a working fluid or ambient air with a lower temperature than the first medium.
