    摘要: A bearing (11) with permanent magnetic elements (18) which are arranged in a rotating and a not-rotating annular series (12, 13). The rotating series (13) are connected to or integrated with a rotating element. A gap (a) is maintained between said two series of magnetic elements due to the repulsive force acting between them. Such a bearing is particularly suitable at hubless propellers for ships, electric generator turbines and pumps. Improvement is achieved by providing at the mutually rotating annular series (12, 13), that the permanent magnetic elements (18) each is accommodated in a magnet holder (15) of ferromagnetic conductive material, said elements (18) being arranged in recesses (16, 21, 22) in the magnet holder (15) of ferromagnetic conductive material.

    摘要: The combustor (1) comprises a stationary structure (2; 102) and at least one tubular rotor (3; 3', 3") supported rotatably about an axis (4) by the structure (2; 102) by means of contactless suspension devices (5-8; 5', 5", 6', 6") there being formed within this rotor at least one combustion chamber (20; 20', 20") having at least one orientated lateral outflow aperture (21; 22; 23, 24) for the ejection of the combustion gases. The rotor (3; 3', 3") has a narrow circumferential slot (30; 30', 30") through which there extend at least one controlled stationary injector (31; 31', 31") of fuel and combustion agent and an associated igniter (32; 32', 32") which is also stationary.
    A control unit (ECU; 35) operates the injector (31; 31', 31") and the igniter (32; 32', 32") according to predetermined procedures, in such a way as to generate a detonation wave which is propagated in the chamber (20; 20', 20"), and to cause the rotor (3; 3', 32) to rotate as a result of the thrust due to the combustion gases emitted through the lateral outflow aperture (21, 22; 23, 24).

    摘要: For the support of deflection rollers(1) in molten metal, ball bearings (3, 4, 5) with low osculation (9) are used in order to compensate temperature-dependent length variations. The thus reduced axial guidance is improved by magnets (10, 19) fitted on the face. For example, mutually repelling permanent magnets (10, 11) are fitted in the turning centre of the shaft (1) and in the opposing frame piece (2).
