Abstract: A connection element having electric insulation-piercing terminal contact elements in a chamber of a receptacle part intended for the connection of electric conductors without stripping them. A sliding part is provided enclosing a part of the insulation-piercing terminal contact elements arranged in the chamber. The connection element permits easy and reliable connection of electrical insulated conductors without a special connecting tool and at the same time ensures as high a current-carrying capacity of the conductor as possible. A locating opening for the conductors is made in a sliding part 1 in an inclined position relative to the longitudinal axis of the sliding part, which longitudinal axis is at the same time the longitudinal axis of the chamber. The conductors are inserted into the insulation-piercing terminal connecting contacts, set at an angle to the wall of the chamber, and make electrical contact with the insulation-piercing terminal connection contacts.

Abstract: In a heat exchanger in the shape of a pot, with a frontal connector for a burner or the like, a lateral water inlet in the base and a water outlet in the region of the frontal connector, water flows through both the base and the jacket of the pot during operation.

Abstract: A miniature motor with a two-pole stator, and a rotor having three or more salient poles each having a core with flanges extending toward both sides thereof and a winding. The rotor is adapted to simulate a two-pole construction by cutting off at least the tip of a flange on either side on a part or all the salient rotor pole cores, thereby limiting the spontaneous-stop angular positions of the rotor to two. One insulating spacer is provided between a plurality of commutator segments of the commutator in such a positional relationship as to come in contact with one of the two brushes when the rotor is at a spontaneous-stop angular position. The motor is prevented from burning and restarting suddenly after a stop since the motor has a self-inactivating function by interrupting current supply at spontaneous-stop angular positions while maintaining motor torque by minimizing the angle of non-conduction to the rotor.

Abstract: A vane control system (2) for a guided missile (1) with at least two vanes (3) has two toothed rings (7, 8), which are arranged in parallel to one another on both sides of the vane axes (18), are driven by pinions (15, 16) which are driven by electric motors and rotate continuously. Two drive gears (11, 17), which engage one of the toothed rings (7, 8) and rotate together with them such that they have opposite directions of rotation, are arranged on each vane axis (18).
