Abstract: To increase selectively the electron emission from a cathode, a control grid is placed above the cathode and osmium or iridium is evaporated through the openings of the grid onto the cathode. On the resulting cathode the coated regions provide a value of work function which is lower than that of the uncoated regions.

Abstract translation: 为了选择性地增加来自阴极的电子发射，将控制栅格放置在阴极上方，并且锇或铱通过栅格的开口蒸发到阴极上。 在得到的阴极上，涂覆区域提供比未涂覆区域低的功函数值。

Abstract: A low mass insulated heater that can be bonded with low thermal drop to an object to be heated consists of a planar arrangement of a heater wire which, after being covered with a thin coating of insulation, is coated with material that is sintered or alloyed to form a metallic sheath. The sheath is brazed directly to a member to be heated to form an integrally bonded structure in which the composite materials all have similar thermal expansion characteristics.
