Abstract: A water jet cutting system includes a supporting surface for supporting an object to be cut, a dispensing device for dispensing a jet of water against the object to be cut, a pressurized water generating apparatus in fluid communication with the dispensing device for supplying pressurized water to the dispensing device, and a support including a crosspiece positioned above the supporting surface for supporting the dispensing device and the pressurized water generating apparatus.

Abstract: In bearing structures which can be converted from a rest shape to an operational shape of larger volume and have at least one flat bearing part (1) and at least one support part (2) movable with and/or detachable therefrom, the problem consists in achieving good shape retention and in particular high resistance to bending without affecting the geometrical adaptability. The solution is achieved through three features: (a) the flat bearing part (1) is essentially resistant to bending in the first normal plane (NE1) and comparatively flexible in at least a second normal plane (NE2) at an angle to the first normal plane; (b) the bearing part (1) has an at least sectionally-curved functional shape; (c) when the bearing structure is in its operational shape the support part (2) is connected in a push-resistant manner with at least one region of the bearing part (1) which extends at an angle to the first normal plane (NE1).
