Abstract: The invention relates to a fuze for a gyratory projectile, including a striker holder movable about a rocker axis perpendicular to the axis of symmetry of the fuze, a primer holder rotatable about an axis of rotation parallel to the axis of symmetry, and a self-destruction device. The latter includes an SD mechanism using the linear acceleration of the projectile upon the departure of the shot to store axial kinetic energy, and a safety mechanism using the centrifugal effects of the projectile during the flight to store radial kinetic energy. The two mechanisms cooperate with each other, and with the striker holder and the primer holder to generate the different storage positions before firing, intermediate upon the departure of the shot, cocked during the flight and of self-destruction at the end of the flight, guaranteeing maximum safety of the projectile in the storage position and maximum responsiveness of the projectile regardless of the scenario encountered during ballistic firing.

Abstract: A Method for detecting stalling of an electric stepper motor (18), with the following steps is shown: a) samples of the voltage at a coil of the stepper motor (18) are taken continuously or in regular intervals, b) a deviation value is determined corresponding to the deviation between the measured voltages of the two samples, and c) the deviation value is used to determine whether the electric motor (18) is stalling. Further, a stepper motor and a heating, ventilation and/or air conditioning system is shown.

Abstract: A stent having a first filamentary element (20) with a proximal end portion and a distal end portion, and being spirally coiled in at least its central portion, and a second filamentary element (30) spirally coiled along its central portion and overlapping the first filamentary element to form a double helix is disclosed along with a method for forming such a stent. At least one end portion of the first filamentary element is ring-shaped to provide increased radial support at that end of the stent.

Abstract: The invention relates to a contact disc (1) for a conducting plate (2) of busbars, comprising a contact surface (3) projecting upwards with respect to the surface of the conducting plate where the contact surface (3) is integral with the conducting plate (2) and where the segment-shaped slots (4a, 4b 14) are arranged all around, to make possible a deformation of the plate without a significant reduction of the surface of the contact disc provided for receiving an electronic component.
