Abstract: The present invention concerns a device comprising a supporting device as a climbing aid for a ski, the supporting device having at least two supporting positions, in which the supporting device prevents a boot that is held in a ski binding from being lowered below a climbing angle between the boot and the ski that is associated with the respective supporting position. It also comprises an adjusting device, which is actively connected to the supporting device and can be directly or indirectly actuated by a user. The device is distinguished by the fact that the adjusting device is formed in such a way that, in an adjusting process, it can move the supporting device from a current supporting position into a new supporting position, the adjusting process being initiated with a time delay in relation to an actuation of the adjusting device.

Abstract: The present invention relates to a method of using foam to remove pollutants and/or heavy metals from a flowable media. The method may include providing a foam that may include cavities wherein the cavities may include an adsorbent composition of iron oxyhydroxy granules. The iron oxyhydroxy granules may have a BET surface area of >100 m2/g and a mean particle size of 0.1 mm-2 mm.
