    摘要： A gettering device installed in a picture display tube includes an annular, channel-shaped metal holder containing an evaporable gettering metal and a heat-activated gas releasing material. The gas releasing material is disposed in the holder against a surface which rapidly increases in temperature in response to inductive heating of the holder. This material is covered by the gettering metal to protect it against deterioration by exposure to moist, high temperature air during tube manufacturing processes occurring after installation of the device. During inductive heating, the temperature of the gas releasing material increases faster than that of the gettering metal and begins releasing gas before the gettering metal begins to evaporate.

    摘要翻译： 安装在图像显示管中的吸气装置包括一个包含可蒸发吸气金属和热活化气体释放材料的环形的通道形金属保持器。 气体释放材料被设置在保持器中抵靠温度响应于保持器的感应加热而迅速增加的表面。 这种材料被吸气金属覆盖，以防止在安装设备后发生的管道制造过程中暴露于潮湿的高温空气，防止其变质。 在感应加热期间，气体释放材料的温度比吸气金属的温度升高，并且在吸气金属开始蒸发之前开始释放气体。
