    • A heater tube is provided for use in a method of producing a diamond or cubic boron nitride (CBN) tipped cutting tool by sintering a mass of crystalline particles to a metal carbide. The heater tube has a cylindrical shape and is comprised of a plurality of windings of an expanded graphite foil which are compressed together. In the method, a heater tube assembly is formed which comprises the metal carbide substrate positioned within the heater tube and a mass of diamond or CBN particles positioned within the heater tube adjacent the substrate. The method includes simultaneously applying sufficient levels of pressure to the heater tube assembly and sufficient levels of electrical current to the heater tube assembly for a sufficient amount of time to cause sintering of the crystalline particles and bonding to the substrate to form a diamond or CBN tipped cutting tool.
    • 提供一种用于通过将大量结晶颗粒烧结到金属碳化物来制造金刚石或立方氮化硼(CBN)尖端切削工具的方法中的加热器管。 加热管具有圆柱形形状,并且由压缩在一起的膨胀石墨箔的多个绕组构成。 在该方法中,形成加热器管组件,其包括位于加热器管内的金属碳化物基体和位于与加热器管相邻的加热器管内的金刚石或CBN颗粒。 该方法包括同时向加热器管组件施加足够的压力水平和足够的电流到加热器管组件足够的时间以引起结晶颗粒的烧结并结合到基底以形成金刚石或CBN尖端 切割用具。

    • A crushable ceramic heater core for an electric heater device which has a cylinder-like body of crushable ceramic material and grooves along the periphery of the body, the grooves being key shaped and adapted to receive a conductive pin in a groove. The invention also includes an electric heater device where such a core has been wound with heater wire and the conductive pin has been inserted in a core groove in contact with the wire, and the wire wound core has been installed in a sheath which has been filed with electoral insulting material. The sheath and its contents are swaged to create a compacted unitary heater assembly. The invention also includes the process for making the wire wound grooved core having a conductive pin therein in contact with the wire winding, and a method for making a heating device having such a core and which has been compacted to a theoretical density. The heater assembly and the method may also include installation of temperature sensing devices.
    • 一种用于电加热器装置的可破碎的陶瓷加热器芯,其具有可压碎的陶瓷材料的圆筒状体和沿着本体的周边的凹槽,所述凹槽是键形的并且适于在沟槽中容纳导电销。 本发明还包括一种电加热器装置,其中这种芯已经用加热丝缠绕,并且导电销已经插入到与导线接触的芯槽中,并且绕线芯已经安装在已经提交的护套中 与选举侮辱材料。 将护套及其内容物锻压以形成压实的整体加热器组件。 本发明还包括用于制造具有与导线绕组接触的导电引脚的绕线槽芯的方法,以及制造具有这种芯并且已被压实成理论密度的加热装置的方法。 加热器组件和方法还可以包括安装温度感测装置。
