Abstract: The present invention relates to a process for carrying out endothermic, heterogeneously catalyzed reactions in which the reaction of the starting materials is carried out in the presence of a mixture of inert heat transfer particles and catalyst particles, where the catalyst particles are regenerated in a nonoxidative atmosphere at regular intervals and the heat of reaction required is introduced by separating off the inert heat transfer particles, heating the heat transfer particles in a heating zone and recirculating the heated heat transfer particles to the reaction zone. The process of the invention is particularly suitable for the nonoxidative dehydroaromatization of C1-C4-aliphatics in the presence of zeolite-comprising catalysts.

Abstract: The invention describes an electrical machine having an armature with armature slots for accommodating armature coils. At least one armature coil is formed from two coil elements which are arranged symmetrically with respect to one another in relation to an axis of symmetry, which runs through the center-point of the armature shaft. The coil elements are connected to two adjacent commutator laminates of a commutator. A first brush, a second brush and a third brush bear against the commutator in a manner such that they can slide. The second brush interacts with the first brush or the third brush.

Abstract: The invention relates to methods for determining a motion vector in a predetermined area of a sequence of digital images by comparing a current image to a preceding image. The current image and the preceding image are prepared by the same filter for image adaptation. Distance vectors between a pixel of a current image and balanced pixels of the preceding image in a predetermined environment are determined, said distance vectors being averaged in order to form a displacement vector for the pixel. The displacement vectors are averaged and the displacement vector is produced.

Abstract: It is the object of the present invention to provide a chest pocket closer tending to retain modern eyeglasses and other kinds of articles in chest pockets of garments. The pocket closer is an essentially U-shaped wire that is removably inserted into the chest pocket and fits invisibly along the inside perimeter of the chest pocket. More precisely, the pocket closer has a bottom width that is smaller than the pocket width and in a free state, before insertion into said pocket, has a top width greater than the pocket width. During insertion of the pocket closer into the pocket, the pocket closer top assumes the width of the pocket by flexing. The flexing imparts lateral tension to the top of the pocket. The combination of the lateral tension on the pocket top, and looseness on the pocket bottom, results in a pocket geometry favorable to retention of articles in chest pockets.
