Abstract: The present invention relates to an ergonomically correct harness for transporting loads. The harness comprises a pair of arcuately shaped pieces which fit over the shoulders of a user. Attached to the rear of the arcuately shaped pieces are two rearwardly extending arms. The rearwardly extending arms are connected at a distal end to a load support arm. Mechanisms for allowing a load to be carried by the harness are attached to the load support arm. Attached to the front of the arcuately shaped shoulder pieces are members for adjusting the position of the harness on the user's shoulders. By adjusting the position of the harness via these members, one can lift a load attached to the harness. The harness of the present invention allows a user to lift a load and transport it using his/her chest muscles, arm muscles, and shoulder muscles. It is not necessary for a user to use his/her knees to lift the load. Further, the back of the user can be kept straight as the user transports the load.

Abstract: The invention relates to a mounting for a turbo-machine rotor. Said mounting is characterized in that radial support of the rotor is assured by one or more permanent magnet bearings. One or more single-thrust sliding bearings provide axial support. The permanent magnet bearings also serve as a lifting device for the sliding surfaces of the hydrodynamic sliding bearings. A force, acting in the opposite direction from the axial force, is generated by axial displacement of the rotor-sided bearing elements of the permanent magnet bearing, in relation to the housing-sided bearing elements, counter to the direction of axial force. This force separates the sliding surfaces of the hydrodynamic sliding bearings from each other in the stopping phases of the rotor. Once it has come to a stop, and when it is in the starting and stopping phases, the rotor is guided by one or more sliding or rolling bearings.
