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: A litho strip for use as an offset printing plate is described which has a composition of 0.05-0.25% Si, 0.30-0.40% Fe, 0.10-0.30% Mg, max. 0.05% Mn, and max. 0.04% Cu. The strip is produced from a continuous cast ingot of the above composition which is hot rolled to a thickness of up to 2-7 mm. The residual resistance ratio of the hot rolled strip is RR=10-20. The cold rolling is carried out with or without intermediate annealing, wherein the degree of rolling reduction after intermediate annealing is >60%. The further processing up to the EC roughening takes place with the microstructure adjusted in the rolling process at <100° C. The litho strip is characterized by a high thermal stability, a good roughening behavior in the EC processes, and a high reverse bending fatigue strength perpendicular to the rolling direction.

Abstract: The invention relates to a method for the production of core preforms for foundry in which a) a mixture of inorganic, refractory foundry sand and a water glass-based inorganic binder is produced, b) the mixture is poured into a heated core box c) the water contained in the mixture is withdrawn by a physical method and d) the core preform is taken out of the core box. The process is characterized by the fact that e) the heated core box is subjected to a depression during filling f) the temperature/dwell time is adjusted after the closing of the core box so that a dimensionally stable and good bearing shell is formed on the edge of the preform g) the preform is immediately removed after opening of the core box and, under the effect of microwaves, is subjected to a complete drying.

The apparatus includes a tub-like having a peripheral wall and a central raised element or cone having tapered outer surfaces, to stabilize the base of the billet during casting and to dislodge the cooled billet as it shrinks.

Abstract: A light-metal strip wheel, in particular for motor vehicles, which includes a wheel disk and a rim. The wheel disk comprises two wheel-disk parts each having a ventilation hole. The ventilation holes have necks that when pressed into one another, secure together the two wheel-disk parts with the two parts separated from one another in the region surrounding the ventilation holes, while coming to rest on one another in a hub region. The space between the two wheel-disk parts in the region surrounding the ventilation holes increases the stiffness of the strip wheel so that the wheel is suitable for accommodating large loads.

Abstract: A motor vehicle door has an outer panel and an inner panel. The outer panel is made up of a pair of double-walled, hollow structural members which are self-supporting. A door lock and door hinges are mounted on the outer panel. The inner panel, which is connected to the outer panel, carries all remaining accessories associated with the door, such as the operating mechanisms for a window mounted on the door.

Abstract: An airbag system includes a cylindrical housing which defines a chamber for a gas generator. The ends of the housing are closed by plugs which are friction welded to the housing. One of the plugs carries an ignition device for a gas generator in the housing. Two arms extend from the housing, and the ends of the arms remote from the housing are provided with lugs for fixing an airbag cover to the housing. The arms, or the arms and the housing, define at least one groove for anchoring an airbag underneath the airbag cover and over part of the housing. This part of the housing is provided with a number of vent apertures which permit gas to flow from the housing into the airbag.
