Abstract: The invention relates to a device for reducing the load on a supporting structure comprising a housing defining a chamber, at least one object having a first face and a substantially opposite second face mounted in the chamber by means of the supporting structure and is displaceable relative to the housing leaving free a gap provided with a seal separating a first section and a second section of the chamber, an exposing means for exposing at least the first face to a gas pressure, thereby generating an upward differential pressure force at least partially compensating the object weight, wherein the seal is supported by a movable part of the housing and the device further comprises a means for adjusting the position of at least said movable part.

Abstract: The invention relates to a device for accumulating inertial energy, comprising a housing (12) defining a rotor chamber (16), at least one rotor (18) having a bottom end face (26) and a substantially opposite top end face (24), the rotor (18) being mounted in the rotor chamber (16) so that it can rotate relative to the housing (12) about a vertical axis of rotation (20) leaving free a gap (32), wherein a seal (36) is provided in the gap (32) separating an upper section (34) of the rotor chamber (16) and a bottom section (38) of the rotor chamber (16), a means (40) for exposing at least the bottom end face (26) of the rotor (18) in the bottom section (38) to a gas pressure which, by comparison with the pressure applied to the substantially opposite top end face (24) in the upper section (34) generates an upward differential pressure force that at least partially compensates for the weight of the rotor (18), and the device is provided with means (40) for reducing the pressure in said upper section (18).

Abstract: A reusable container, in particular for environmentally harmful substances, such as paint, adhesive and the like, comprises a container body (1), the inside and/or outside of which is provided with a protective coating (7, 6) which consists of a material which is solvent-resistant at application temperature and at a raised temperature is soluble or softenable in a solvent, preferably water. This material is preferably polymethyl methacrylate.
