Abstract: A method of manufacturing an object by joining a first component and a second component. The first component comprises metal powder with a first alloy composition and a first soluble binder, and the second component comprises metal powder with a second alloy composition and a second soluble binder. They may further comprise ceramic powder. At least one of the surfaces to be joined is dissolved before they are brought in contact, or a mixture of metal powder with a third alloy composition and a dissolved third binder is arranged there between. The chemical differences between the first, second, and third alloy compositions are within predetermined limits. The components are sintered or oxidized together whereby it is possible to obtain an object wherein the transitions between the material phases from the joined components are close to inconspicuous when analysed with scanning electron microscopy.

Abstract: The present invention relates to a magnetic gear comprising a first magnetic rotor with a first shaft; and a second magnetic rotor with a second shaft; a support structure, with a first end shield and a second end shield connected by a stat or support element. A first bearing attached to the first end shield supports the first shaft and a second bearing supports the second shaft. The first and second magnetic rotors are displaced in axial direction from each other in an axial gap; and the first shaft and shaft are approximately aligned in opposite axial directions; and a plurality of magnetic flux conductors encircles the first and second magnetic rotors, thereby conducting magnetic flux from the first magnetic rotor to the second magnetic rotor. The magnetic gear comprises a dividing wall arranged in the axial gap between the first magnetic rotor and the magnetic second rotor, to separate a first chamber from a second chamber.

Abstract: The invention relates to a heating system (200) for heating of a fluid. The heating system comprises a supply connection (201) in fluid communication with a supply of fluid to be heated. It further comprises a structured body (108) arranged for heating of the fluid during use of the heating system. The structured body comprises a macroscopic structure (21) of electrically conductive material, the macroscopic structure comprising at least one channel (22) through which the fluid can flow. The heating system further comprises at least two conductors (103,114) configured to electrically connect the structured body to at least one electrical power supply. The at least two conductors are electrically connected to the structured body at a first end (204) and at a second end (205), respectively, of a conductive path within the structured body. The structured body is configured to direct an electrical current to run along the conductive path from the first end to the second end thereof. The electrical power supply is configured to heat at least part of said structured body to a temperature of below 400° C. by passing an electrical current through said structured body during use of the heating system.
