    摘要: The present invention relates to a gelled foodstuff for aquatic animals, mainly for fish, prawns and invertebrates living in fresh water or salt water. This gelled foodstuff can be used as a substitute for frozen foodstuff in order to feed cold-water or hot-water exotic fish in fishbowls. The preferred foodstuff is a foodstuff for exotic fish that comprises from 0.001 to 50 % of a gelling agent, from 0.1 to 90 % of a natural nutriment and, according to its intended use, other additives for a water content of between 20 and 99 %. The ideal foodstuff is a foodstuff that comprises from 0.1 to 10 % of a gelling agent, from 1 to 20 % of a natural nutriment and, according to its intended use, other additives for a water content of between 50 and 99 %.

    摘要: The invention relates to a resilient, multi-component wheel for rail vehicles, comprising a rim (2) and hub (11) as well as an elastic element (6, 8) removably inserted between said rim and hub. Said elastic element (6, 8) is configured as a concentric, separate part consisting of a central disk (7), two larger outer disks (5, 9) and two elastomer rings (6, 8) positioned between said disks. Said elastomer rings (6, 8) are made of a plastic material or rubber, can have different shapes depending on the desired type of compressive stress or shear stress and are connected to the disks (5, 9) in a non-positive manner.
