    Abstract: In a preferred form of the invention a disc brake rotor is disclosed which is formed of a hypereutectic gray iron composition having a relatively high capacity for damping mechanical vibrations, excellent wear resistance and high thermal conductivity. The composition is a pearlitic gray iron having a carbon equivalent of at least 4.5. Carbon is present in combined form in pearlite and as ASTM Type-A flake graphite.

    Abstract: An air convection range surface heater has a centrifugal air impeller for recirculating electrically heated air and includes fixed stator vanes operative with the impeller to increase the mass airflow through a heat exchanger and into an air circulation space adjacent a utensil to thereby distribute maximum heat flux to the utensil. The unit provides both inner and outer cooperating spill chambers that readily separate the heated air from spillage to eliminate fire and electrical short circuiting hazards. A solid state air monitor and control circuit is provided for throttling power input to limit the maximum air temperature in the unit''s heat exchanger at any desired value.

    Abstract translation: 空气对流范围表面加热器具有用于再循环电加热空气的离心式空气叶轮,并且包括与叶轮一起操作的固定定子叶片,以增加通过热交换器的质量空气流和邻近餐具的空气循环空间,从而将最大热通量分配到 器具。 该设备提供内部和外部协作的泄漏室,其容易将加热的空气与溢出物分离,以消除火灾和电气短路危险。 提供固态空气监测和控制电路用于节流电源输入,以将设备热交换器中的最大空气温度限制在任何所需的值。
