    • A process for collecting microcapsules containing a liquid fill formed by an encapsulation head comprising maintaining a rotating substantially uniform layer of a cushioning powder between a capsule forming zone and a capsule collecting zone, expelling capsules as formed from the capsule forming zone onto a uniform layer of cushioning powder, and moving the capsules radially along said layer and the capsule collecting zone. The invention also comprises the apparatus involved which comprises an encapsulation head for expelling capsules, a powder-coated platform located below the encapsulation head for receiving said expelled capsules, means for rotating said platform to cause said capsules to move radially and fall from said platform, and a moving surface located below said platform to collect said capsules falling from said platform.

    • A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and connected with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics, and to be inert in dry conditions and compatible with the insulator components. The dopant is positioned within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway or diffuse through the housing. The activated dopant then creates a deposit or stain on the outer surface of the insulator housing. The dopant comprises an oil-soluble dye, an indicator, or a stain compound that can either be visually identified, or is sensitive to radiation at one or more specific wavelengths. The dopant could also be formulated by a nanoparticle enabled material. Deposits of activated dopant on the outer surface of the insulator can be detected upon imaging of the outer surface of the insulator by appropriate imaging instruments or the naked eye.
    • 描述了一种用于通过放电活动条件提供由于应力腐蚀开裂,闪光或棒的破坏而引起的即将发生的故障的复合绝缘体。 复合绝缘体包括由聚合物壳体包围并与杆的任一端上的金属端配件连接的玻璃纤维棒,掺杂有基于染料的化学掺杂剂。 掺杂剂位于玻璃纤维棒的外表面附近。 掺杂剂配制成具有迁移和扩散特性,并且在干燥条件下是惰性的并且与绝缘体组分相容。 掺杂剂定位在绝缘体内,使得当绝缘体的外表面通过渗透通道将水分穿过壳体穿过壳体时,掺杂剂将被激活并将从相同的渗透通道中浸出或扩散通过 住房。 活化的掺杂剂然后在绝缘体外壳的外表面上产生沉积物或污渍。 该掺杂剂包括油溶性染料,指示剂或染色剂,其可以在视觉上被鉴定,或对一个或多个特定波长的辐射敏感。 掺杂剂也可以由具有纳米粒子的材料制成。 可以通过适当的成像仪器或肉眼对绝缘体的外表面进行成像后,检测绝缘体外表面上活化的掺杂剂的沉积。
