The porous composites comprise a pressure-molded composite of carbon particles and thermoplastic resin particles which have a particle size distribution of 0 to 45 .mu.m. The pores are formed by dry mixing a water-leachable salt with a pore size distribution of 5 to 200 .mu.m with the carbon and resin mixture and water extracting the salt to form the porous composite.

摘要： A method for improving the magnetic properties of a core fabricated from at least one strip of amorphous metal wound about itself to form adjacent laminations in the shape or a closed loop is disclosed. In accordance with the method, a force in tension of predetermined strength is applied to the loop from the innermost lamination of the loop outwardly. While this tensile force is being applied, the loop is annealed simultaneously and subjected to a magnetic field of predetermined strength.

摘要： A method and apparatus for detecting rotor faults in an induction motor. Such induction motors have a stator and a rotor comprising a multiplicity of rotor bars. The flux around the rotor bars is detecte at a predefined flux detection point in the motor, generally by using a coil wound around one of the stator teeth. A synchronization signal is generated once per revolution of the rotor when a predefined position on the rotor is closest to a stator reference point, usually the flux detection point. The detected flux signal is filtered to reject signals in a predefined frequency band around the frequency at which the rotor bars pass the flux detection point, and then it is synchronously time averaged. Averaging requires that corresponding portions of the flux signal, for a series of rotor revolutions, be added, and the synchronization signal is used as a reference for matching corresponding portions of the flux signal. Statistically significant peaks in the resulting time averaged signal indicate the presence of a rotor bar fault, and the location of such peaks corresponds to the location of rotor bar faults with respect to the predefined position on the rotor.
摘要翻译： 一种用于检测感应电动机中的转子故障的方法和装置。 这种感应电动机具有定子和包括多个转子条的转子。 转子条周围的磁通通常通过使用卷绕在一个定子齿上的线圈在电动机中的预定的通量检测点处被检测。 当转子上的预定位置最靠近定子参考点（通常是通量检测点）时，每转一圈产生同步信号。 对检测的通量信号进行滤波，以在转子条通过通量检测点的频率周围的预定频带中抑制信号，然后同步地进行时间平均。 平均要求对于一系列转子旋转的通量信号的相应部分被加上，同步信号被用作用于匹配通量信号的相应部分的参考。 所得到的时间平均信号中的统计学显着的峰值表示存在转子条故障，并且这种峰值的位置对应于转子条故障相对于转子上的预定义位置的位置。

摘要： An actuator for an electrical circuit interrupter utilizes a gas generating chemical charge which is carried in its own cylindrical operating chamber. These power units are stored in a magazine and are fed into an operating position by a transfer cylinder in the form of a rotary turret head having cylindrical cutouts for the power units. The operating position specifically is with a chamber juxtaposed opposite one of the two input ports of a duplex power cylinder which is connected to the operating linkages of the interrupter itself. After the power unit has operated to open the interrupter, it is ejected. The operating action is linked to a duplicate set of a storage magazine and transfer cylinder for the close direction so that while the interrupter is opening the duplicate close actuator portion is readied for instantaneous action. This provides for a fast reclosing duty cycle and multiple operations. Also, for high operating speeds and good reliability.

摘要： An automatic compensation circuit for use with an analog multiplier is disclosed. At regular intervals at least one input to the analog multiplier is constrained to be zero for a short time. During this time a sample and hold circuit retains the pre-existing output voltage and a feedback circuit is activated which adjusts the output voltage of the multiplier to zero, thereby providing an accurate multiplied or product signal, typically representing power consumption, which is adjusted or compensated for the effects of any internal errors occurring within the analog multiplier.

摘要： A cooling apparatus and related method for a continuous casting apparatus includes a series of spray nozzles for spraying a coolant against one surface of a moving chill substrate. The invention apparatus includes an enclosure having vacuum applied thereto for preventing migration of the sprayed coolant from the surface against which it is sprayed to the surface contacting the molten solidifying material. Any coolant having a tendency to escape along sealed edges of the enclosure is forced back into the enclosure by the pressure gradient. The edges are sealed by elongated plastic rods. Additionally, scrapers are provided for removing remanent coolant from the sprayed surface. The coolant is sprayed at a high velocity to increase its heat transferring efficiency.
