摘要： An apparatus for the high voltage treatment for a cathode ray tube including a neck having one end closed with a stem and housing an electron gun and stem pins for a focus electrode and other electrodes of the electron gun, establishes a high pressure gas atmosphere around the neck, and establishes a voltage which is sufficiently higher than the operating voltage of the cathode ray tube between the stem pins when the high pressure gas atmosphere. In order to prevent a creeping discharge due to the voltage applied to the stem pins, the temperature of the neck is maintained above the temperature of said high pressure gas atmosphere during the voltage application. In an alternative method, the dew point of the high pressure gas atmosphere is set at, at most, 25.degree. C.

摘要： Raw coal is caused to fall through a coal feed pipe and onto a table so as to be pulverized by a roll. Fine coal particles and coarse coal particles resulting from pulverization are moved upward between an auxiliary classifier cone and a mill casing by hot air supplied from below the mill casing. The hot air (upward stream) carrying the fine coal particles and the coarse coal particles moves across a space of triangular cross section formed between the inverted conical body of the auxiliary classifier cone and the side wall of the mill casing and is forced through blowoff openings defined between deflector plates so as to flow as a lateral rotative stream toward a rotary classifier. Upon impinging the downward-inclined rotating vanes of the rotary classifier, the coarse coal particles are sprung back toward a lower portion of the auxiliary classifier cone and are separated from the fine coal particles. The fine coal particles separated from the coarse coal particles are ejected out of the roller mill together with the upward air stream through a pulverized-coal eject pipe. Coarse coal particles sprung back toward the lower portion of the auxiliary classifier cone move along the inner surface of the auxiliary classifier cone and fall onto the table so that they are re-pulverized by the roll.
摘要翻译：使原煤通过供煤管落到台面上，以便通过轧辊粉碎。由粉碎产生的细煤颗粒和粗煤颗粒在辅助分级锥体和轧机壳体之间通过从轧机壳体下方供应的热空气向上移动。携带细煤颗粒和粗煤颗粒的热空气（向上流）穿过形成在辅助分级锥体的倒圆锥形体和磨机壳体的侧壁之间的三角形横截面的空间，并被迫通过吹气口限定在偏转板之间，以便作为横向旋转流朝向旋转分选机流动。当撞击旋转分选机的向下倾斜的旋转叶片时，粗煤颗粒向辅助分级锥体的下部弹回并与细煤颗粒分离。与粗煤颗粒分离的细煤颗粒与向上的气流一起通过粉煤喷射管从辊磨机中排出。沿着辅助分级锥体的内表面向辅助分级锥体的下部弹回的粗煤颗粒沿着辅助分级锥体的内表面移动并落在工作台上，以便它们被辊重新粉碎。
