摘要： An improved electrostatically-focused image intensifier tube, and a night vision device having such a tube, is substantially free of the spurious bright spots generally known as "PC Flash". The improved image intensifier tube includes an insulator which resists emission of electrons into the interior cavity of the tube, or a structure to capture such emitted electrons before they can fall into a microchannel plate of the tube and cause the PC Flash. A method of making such an image intensifier tube is also disclosed.
摘要翻译：改进的静电聚焦图像增强管和具有这种管的夜视装置基本上没有通常被称为“PC闪光”的虚假亮点。改进的图像增强管包括阻止电子发射到管的内部空腔中的绝缘体，或者在将它们落入管的微通道板之前捕获发射的电子并引起PC闪光的结构。还公开了制造这种图像增强管的方法。

摘要： A reinforcement assembly for use in the hand access hole of a tubular shaft. In one embodiment, the assembly includes a pair of units placed opposing each other with one being inside the shaft and the other being outside the shaft. Each unit has a plurality of tenons that mate with open spaces of the opposing unit, and each has a flange surrounding the tenons that contact the shaft in the area immediately surrounding the hand hole. The two units are attached to each other and to the shaft by bolts or other suitable fastening devices. In another embodiment of this invention, the pair of units are positioned one inside the other with at least one mating mortise and tenon union for securely linking the units. A typical application of the assembly is reinforcement of the area surrounding the hand hole of a utility pole.

摘要： Method and apparatus for joining a first structural element, having a passageway formed therein which opens to the exterior thereof, to a second element. A plurality of members are assembled into a joining device which is then nested inside of the passageway. The members are then moved with respect to each other to enlarge the size of the joining device so that the members engage the wall of the passageway in supporting contact therewith. The members of the enlarged joining device are then secured together into a unitary support block, with the members in supporting contact with the passageway wall. The unitary support block is connected to the second element. Unique member components, member securing means, member moving means, and the like form a new and useful apparatus.
