摘要： A gland which is installed in the hole of a wall between two different atmospheres to prevent the leakage of a fluid from the one side to the other side of the wall along the outer sheath of an electric cable has a tubular metallic housing which is sealingly installed in the hole and into which the cable extends. The interior of the housing is filled with a hardened filler material which completely surrounds bare portions of conductors. Beads are formed on such bare portions. Sleeves are shrunk onto the bare portions of the conductors between the respective beads and insulators for the conductors. A tension reducing clamp surrounds the outer sheath of the cable in the housing. The aperture at one end of the housing contains an O-ring which is biased against the external surface of the outer sheath of the cable and against the surface surrounding the aperture by a second ring. The conductors are further surrounded by additional insulators which extend from the filler material by way of an open end of the housing. The beads are welded or soldered onto the bare conductors between the respective pairs of insulators.

摘要： An explosion-proof canned electric motor for use at elevated temperatures wherein the upper portion of the motor housing contains the stator windings and the rotor and is connected with a terminal box by means of a tubular heat barrier. The terminal box is disposed at a level below the upper housing portion and has an annular venting orifice in the lowermost part thereof so that condensate which accumulates in the housing flows toward the orifice. Such condensate is absorbed by a cake of diatomaceous earth or another suitable porous desiccant which is placed into the path of condensate flow toward the orifice. The desiccant also removes moisture from air which flows into the terminal box, and the desiccant is relieved of accumulated moisture during starting of the motor when the air in the housing expands as a result of heating and flows through the pores of the desiccant on its way into the orifice.
摘要翻译：一种用于高温使用的防爆罐式电动机，其中电动机壳体的上部包含定子绕组和转子，并通过管状隔热壁与接线盒连接。接线盒设置在上壳体部分的下方，并且在其最下部分具有环形排气孔，使得积聚在壳体中的冷凝物朝向孔流动。这种冷凝物被硅藻土的滤饼或另一种合适的多孔干燥剂吸收，该干燥剂被放置在朝向孔口的冷凝物流的路径中。干燥剂还可以从流入接线盒的空气中除去水分，并且当外壳中的空气由于加热而膨胀时，干燥剂在电动机启动期间缓解了积聚的湿气，并在其途中流过干燥剂的孔进入孔口。

摘要： A pump for circulating cooling and lubricating liquid is driven by a motor which comprises a central rotor; a tubular housing coaxially surrounding the rotor and normally filled by the cooling and lubricating liquid; and a stator coaxially surrounding this tubular housing. Heating elements are provided between the coil ends of the stator and the tubular housing for heating the liquid in this housing, during or after a shutdown of the motor, when the liquid is likely to have congealed or at least to have become viscous.
