摘要： A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings including an axial bearing to support the impeller axially in the cavity. The axial bearing includes adjacent impeller magnets and adjacent stator magnets with axially aligned polarities and reverse polarities with respect to adjacent magnets. A motor includes impeller magnets on the impeller and coils and poles associated with the stator. Radial permanent magnet and electromagnetic bearings are also included. The magnetic bearings and the motor have stator magnets or coils and poles disposed radially across the fluid passage from corresponding impeller magnets to define an annular gap positioned radially between the impeller and the stator, and positioned radially between all of the plurality of magnetic bearings, creating a straight through blood path without secondary flow paths.
摘要翻译：血泵具有可旋转地设置并通过包括轴向轴承的多个磁性轴承磁性地悬挂在定子的空腔内的叶轮，以便在空腔中轴向地支撑叶轮。轴向轴承包括相邻的叶轮磁体和相邻的定子磁体，其相对于相邻的磁体具有轴向对准的极性和相反的极性。电动机包括叶轮上的叶轮磁体和与定子相关联的线圈和极。还包括径向永磁体和电磁轴承。磁性轴承和电动机具有定子磁体或线圈和磁极，其径向跨越来自相应的叶轮磁体的流体通道设置，以限定径向位于叶轮和定子之间并且径向位于所有多个磁性轴承之间的环形间隙，从而产生直通血路，无二次流路。

摘要： This invention provides an improved apparatus for non-contact quantum mechanical heating of thermoplastic fibers by resonant energy absorption of laser energy by the fiber. In one embodied form, the unique apparatus for continuous heating of thermoplastic fibers comprises a) a laser producing a CO continuous wave laser beam of resonant frequency for the prescribed fiber being treated; b) a mechanism for traversing the fiber to be treated across the path of the laser beam in a prescribed direction to the beam of radiation from the laser source; c) a mechanism for adjusting the rate of traversement of the fiber to maintain the temperature of the thermoplastic fiber within a temperature range of about five percent below the melting point of the thermoplastic fiber to continuously heat the fiber by resonant energy absorption of the laser beam. In a presently preferred embodiment, the unique micro heater apparatus is provided comprising a laser heater furnished with a collimator steering mirror and back reflector, to enhance the heating efficiency of the non-contact quantum mechanical process. The unique micro heater apparatus accordingly provides a source of non-contact heat before, after or during a false twisting process or fiber stretching process.

摘要： A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings (passive permanent and active electromagnetic) having impeller magnets on the impeller and stator magnets or coils/poles on the stator. A motor includes impeller magnets on the impeller and coils/poles associated with the stator. A single, annular blood flow path extends axially through the cavity between the impeller and the stator, and between the impeller magnets on the impeller and the stator magnets or the coils/poles on the stator.
