Abstract: A method for starting up an electromagnetic actuator operating an engine cylinder valve. The actuator has two spaced electromagnets, between which an armature, connected to the cylinder valve, is reciprocated against a restoring spring from a center position to lie against a magnet pole face. An ECU alternatingly supplies the electromagnets with a capturing current, the level of which is regulated as a function of the approach of the armature toward a pole face, as detected by a sensor assembly. A reference temperature is detected for the magnets, and, at a normal temperature, the armature starts oscillating due to the alternating energization of the electromagnets, and is brought into contact with a pole face. Or, at a low temperature level, one of the electromagnets is supplied with a high current pulse.

A holding shell is positioned in the projectile and is exposed to a force of an air current during projectile flight for causing the holding shell to fly off the projectile. A force-transmitting component connects the holding shell with the slide for displacing the slide from the safety position into the firing position upon movement of the holding shell away from the projectile.

Abstract: The contact connector arrangement for optical waveguides of the internationally standardized SC connector whose connection ends are each formed by a male connector comprises a connector housing (7) which receives at least two male connectors (6), is used for the manual handling of the plug-in process and cooperates by way of coupling means (8) in a positive locking manner with predetermined plug-in openings of an electric connector system RJ 45 or RJ 11 or the like. This ensures that the connection ends of optical waveguides which are readily manufactured as male connectors can be used directly for modular electric connector systems such as RJ 45 or RJ 11.

Abstract: A projectile fuze includes a detonator carrier having a safety position and an armed position; a pin having a blocking position in which it holds the detonator carrier in the safety position and a releasing position in which the pin allows the detonator carrier to move into the armed position; a spring urging the pin into the releasing position; a pyrotechnical delay element exposed to hot propellant gases for causing ignition and combustion of the delay element; and a pin-supporting component maintaining the pin in the blocking position against a force of the spring.

Abstract: A simplified method for producing a lead for color pencils, cosmetic pencils and colored chalk with good down stroke behavior involves mixing powdered or granular base materials containing a thermolabile, polymeric binding agent, inorganic filler materials and a coloring agent with water and then extruding the mixed materials to form raw leads, which extruded material is subsequently heat treated at the binding agent decomposition temperature for a time sufficient to partially decompose the binding agent. Enough water is mixed with the base material to achieve a lead mass of approximately 5 parts by weight of base material and 1 part by weight of water.
