Abstract: The invention relates to a method for producing a metal foam body, according to which a molten material containing gas is prepared and said molten material is left to solidify, thus forming a metal foam body. The aim of the invention is to produce high-quality metal foam bodies with a desired shape, without requiring complex equipment and whilst reducing the safety risk for the operating personnel. To achieve this, the material used is fused under atmospheric pressure and gas is simultaneously and/or subsequently introduced into the molten metal. The latter is then poured into a mold and is left to solidify, whereby the ambient pressure is reduced at least temporarily.

Abstract: When stacking stackable items in layers on pallets, intermediate layers of paper/cardboard/film are often used for preventing loss of the items during transport. Even though the intermediate layers ensure to a large extent that items do not fall off the pallet, it cannot be entirely prevented that some of the stacked items fall off because the stacked items slid on the intermediate layers. Special intermediate layers are known, having a surface coated with non-skid coating which highly counteracts the unwanted sliding of the items in the layers stacked on a pallet. However, the laying of intermediate layers with non-skid surfaces constitutes a problem as the individual pieces of non-skid coated intermediate layer will adhere to each other. Thus, there is provided a method and a sheet dispenser where pieces of intermediate layers are successively dispensed, and where these layers are coated with a non-skid coating during dispensing.

Abstract: A motor vehicle lock with a blocking element (2), with a electrical opening drive (3) for the blocking element (2), with control electronics (8) in the motor vehicle lock or separately from it in the motor vehicle, by which individual functions of the motor vehicle lock can be electrically triggered, and a lock mechanism by which individual functions can also be mechanically triggered. The opening drive (3) has a drive element (6) which can be driven in two opposing directions of motion, movement of the drive element in the first direction of motion releases or open the blocking element (2) and movement in the second direction of motion turns on (or off) the second function of the motor vehicle lock. The lock has an especially simple structure since turning off the second function takes place without moving the opening drive (3) in the second direction of motion exclusively by electrical control.
