Abstract: Use of certain alkoxylates as an adjuvant for agrotechnical applications The present invention relates to the use of specific amphiphilic alkoxyates as synergistic adjuvant for agrotechnical applications. Suitable agrotechnical compositions are also described. Thus, the addition of such alkoxylates makes possible an accelerated uptake of active ingredients by the plant. The alkoxylates to be used are alkoxylates based on branched alcohols such as 2-propylheptanol, C13-oxo alcohols and C10-oxo alcohols.

Abstract: For locking individual gears, a “rod-type” locking element is provided which extends in the axial direction over several operating elements and which, in the individual possible transmission shifting positions, in each case, engages with some of the existing operating elements. When one of the operating elements is shifted out of its neutral position into a shifting position, the locking rod is brought into a locking engagement with at least some of the existing operating elements.

Abstract: In order to improve a process for the production of a composite consisting of electrode material, catalyst material and a solid-electrolyte membrane for an electrochemical cell, in particular a fuel cell, with which solid-electrolyte material is brought into pore-deep contact with the electrode material and the catalyst material by softening it, such that this can be carried out as effectively and inexpensively as possible it is suggested that a catalytic powder comprising electrode material, catalyst material and the solid-electrolyte material be produced, that a catalytic layer be produced on a carrier from the catalytic powder, that the catalytic layer be heated on a side facing away from the carrier to soften the solid-electrolyte material and that subsequently the catalytic layer be applied under pressure to the solid-electrolyte membrane while the solid-electrolyte material is still softened in order to form a composite.

Abstract: A crank mechanism for a lift-slide cover of a motor vehicle having a crank arm with which a shaft can be rotated which is connected with a drive for a lift-slide mechanism of the lift-slide cover. The crank arm is pivotable relative to the shaft. By swiveling the crank arm a sliding piece is slid perpendicularly to a locking pin disposed parallel to the shaft and lifts this locking pin against the force of the spring. Since the sliding piece and the locking pin have oblique surfaces, the locking pin engages into the sliding piece after lifting.
