Abstract: The invention relates to a method for manufacturing a surface-alloyed cylindrical, partly cylindrical or hollow cylindrical structural member where in the zone of incidence of the energy beam there is formed a locally bounded melting bath with a heating and melting front, a solution zone and a solidification front. At the side of the energy beam the hard material powder is deposited via a conveyor device in the direction of gravity and is supplied co-ordinated with the feed movement of the workpiece in a width which corresponds to the width of the linear focus and a layer height of 0.3-3 mm is thereby produced. The hard-material powder supplied to the workpiece surface in the heating front of the melting bath is heated by an energy beam at a wavelength of 780-940 nm and in contact with the liquefied matrix alloy the powder is immediately dissolved in the melting bath.

Abstract: The invention relates to a method of controlling function units of a motorcar or of devices (1a, 1b) installed in a motorcar, via speech signals, in which

Abstract: An electric lighter for a vehicle includes a lighter plug insertable into a dashboard socket having a bimetallic yoke engageable with an end of the plug for energizing the glow coil of the plug. An overload protective device is disposed in the socket and comprises a bimetallic snap-action disc disposed immediately below the yoke and connected electrically in series therewith. The snap-action disc has a first shape in its operating condition where it completes the circuit to the glow coil through the yoke and assumes a second shape when it snaps to its switch-off position in response to an overload condition to open the circuit to the glow coil. The snap-action disc remains in its switch-off position after cooling and must be manually reset to its operating position to restore operability of the lighter by the engagement of a manually actuated reset device associated with the socket with a peripheral portion of the snap-action disc.

Abstract: The electric cigarette lighter combines the handling advantages of rotating operation with the contacting advantages of pressing operation. A shaft is rotationally fixed to a rotary knob but axially slidable with respect thereto. A heater body affixed to the shaft is brought from an initial position to an operating position through a rotating movement of the rotary knob and a superimposed rotary thrust movement of the shaft. The heater body is automatically returned from the operating position to to the initial position through likewise superimposed rotary thrust spring forces of one or two restoring springs.
