    • A method and a HIP can structure for hot isostatically pressed (HIP) production of flat sheet metal matrix composites having a dimension greater than about 4.times.5 inches. The HIP can is constructed so that most of the expensive components are reusable for further processing of other composites. The side walls of the HIP can have reduced thickness relative to the top and bottom walls and the can has a reinforced centerpiece between the two composites used in the example. Molybdenum foils are utilized to separate the composites from the stiffening structure so that when the HIP can is opened by breaking the weld at one of its wings, the components of the can and the composites come apart so that the most expensive structural members of the HIP can be reused.
    • 一种方法和HIP可以结构用于热等静压(HIP)生产尺寸大于约4×5英寸的平板金属基复合材料。 构建HIP罐使得大多数昂贵的组件可重复使用以进一步处理其它复合材料。 HIP的侧壁可以相对于顶壁和底壁具有减小的厚度,并且罐在该示例中使用的两个复合材料之间具有增强的中心件。 使用钼箔将复合材料与加强结构分离,使得当HIP罐通过在其一个翼部断裂焊接而打开时,罐体和复合材料的部件分离,使得HIP中最贵的结构构件 可以重复使用

    • A seal-less pump and electric motor assembly includes a motor rotor fixed to a driving shaft connected to an impeller in the pump assembly. The rotor and impeller are enclosed in a common housing such that the rotor rotates within any fluid being pumped by the impeller. The portion of the housing circumscribing the rotor includes a plurality of axially extending, circumferentially spaced strips of magnetic material penetrating through plastic material of the housing. Each of the strips coincide with corresponding ones of the pole teeth of a motor stator circumscribing the outer portion of the housing such that the strips in the housing act as extensions of the pole teeth. In one embodiment, the strips of magnetic material in the housing are formed by molding powdered iron in a plastic binder material. The strips are then placed in a mold in which the housing is formed by injecting plastic. The plastic binder in the strips melds with the injected plastic to form a continuous housing for enclosing the rotor. The ferromagnetic material strips extend through the housing and are spaced from the rotor surface by a normal air gap distance so as to improve the efficiency of the motor by having the magnetic strip act as extensions of the motor stator pole teeth. In one embodiment, the rotor includes a shaft, a core including a molded magnetic powder and plastic composite material surrounding the shaft, and an annular corrosion resistant electrically conductive tube surrounding the core.
    • 无密封泵和电动机组件包括固定到连接到泵组件中的叶轮的驱动轴上的马达转子。 转子和叶轮被封闭在公共壳体中,使得转子在由叶轮泵送的任何流体内旋转。 围绕转子的壳体的部分包括穿过壳体的塑料材料的多个沿轴向延伸的周向间隔开的磁性材料条。 每个条与电机定子的相对应的一个限定外壳的外部部分的极齿重合,使得外壳中的条带作为极齿的延伸部分。 在一个实施例中,壳体中的磁性材料条通过在塑料粘合剂材料中成型铁粉而形成。 然后将条带放置在通过注射塑料形成壳体的模具中。 条中的塑料粘合剂与注射的塑料粘合以形成用于封闭转子的连续的壳体。 铁磁材料带延伸通过壳体并且与转子表面间隔开正常的气隙距离,以便通过使磁条作为电动机定子极齿的延伸来提高电动机的效率。 在一个实施例中,转子包括轴,包括模制磁性粉末的芯体和围绕该轴的塑料复合材料,以及围绕该芯的环形耐腐蚀导电管。
