Abstract: An electric fail-safe actuator includes a speed reducer/gear assembly housing arranged between one or more electric motors, and a rotation to linear transformer including a roller or ball nut and a screw, or a nut and a roller or ball screw. The speed reducer/gear assembly housing is connected to an actuator housing via a counter hold release mechanism, allowing the speed reducer/gear assembly housing to co-rotate with a rotational side of the rotation to linear transformer when the counter hold release mechanism is released.

Abstract: The present invention relates to a method of forming a joint bonding together two solid objects and joints made by the method, where the joint is formed by a layer of a binary system which upon heat treatment forms a porous, coherent and continuous single solid-solution phase extending across a bonding layer of the joint.

Abstract: The main function of the invention is the rectification of angular errors due to torsion in long and slim axles for electric motors of which a rotor and stator are divided into two or more sub motors, and wherein rotors are coupled to a common axle and wherein two or more stator elements are supplied with equal electrical phases from a power supply cable. The invention is a system and a coupling between rotor elements and an axle extending through the system, the purpose being to dynamically compensate for angular errors due to torsion in the axle between two or more rotor elements in which the torsion angle would influence negatively the electrical efficiency of the rotor elements. The object of the invention is the angular positioning of rotor elements so that the poles are electrically synchronous, thereby avoiding reduction of the electrical efficiency due to torsion in the axle.
