Abstract: A rail system for a conveyor vehicle capable of traveling along the rail system for storage of piece goods into a storage rack or retrieval of piece goods from a storage rack includes a first running rail, a second running rail and a connecting device, which includes a positive locking connection between the ends, directed toward one another, of the first running rail and second running rail. At its end, the first running rail forms a first interlocking element and a first surface portion. At its end, the second running rail forms a second interlocking element and a second surface portion. Therein the first interlocking element and second interlocking element engage in one another in complementary manner and the ends of the first running rail and second running rail abut at the surface portions in a butt-jointed manner. Furthermore, a warehouse system has such a rail system.

Abstract: Apparatus and methods provide for a non-linear scarf joint and a method for joining two components utilizing a non-linear scarf joint. A non-linear scarf joint includes multi-planar surfaces on connection ends of two components being joined to create a structure. Each multi-planar surface includes a first faying surface, a second faying surface, and a transition faying surface joining the first and second faying surfaces. A transition scarf angle associated with the transition faying surface is different than scarf angles associated with the first and second faying surfaces.

Abstract: A rail joint arrangement comprises two rails. The rails have adjacent rail ends separated and thereby forming a gap. The rails have a top end containing a rail head and a bottom end. The gap is defined between the top end and the bottom end of the rails, and the width of the gap is non-uniform throughout its entire length. In addition, the rail joint arrangement comprises at least one electric insulator positioned within the gap. The rail joint arrangement is fastened together by a rail joint bar attaching the two rails together.

Abstract: An integrated ferroelectric/CMOS structure which comprises at least a ferroelectric material, a pair of electrodes in contact with opposite surfaces of the ferroelectric material, where the electrodes do not decompose at deposition or annealing, and an oxygen source layer in contact with at least one of said electrodes, said oxygen source layer being a metal oxide which at least partially decomposes during deposition and/or subsequent processing is provided as well as a method of fabricating the same.
