摘要： A filter arrangement for a vacuum toilet system includes a filter element arranged in a filter housing connected to a waste water tank of the vacuum toilet system. The filter element includes a polytetrafluoroethylene (PTFE) filter membrane on the inlet side thereof, a filter support material supporting the PTFE membrane, and a support cage, to form a filter cartridge. The filter is preferably a pleated cylindrical filter with the inlet side on the inside of the cylinder. The arrangement preferably further includes a rinsing nozzle that rinses contaminants from the inlet side surface of the filter element, to flow down into the waste water tank. This rinsing, together with the low adhesion and the surface filtration principle of the PTFE filter membrane, prevent clogging of the filter.

摘要： A system of interconnected heating conductors, suitable for preventing freezing of water lines in an aircraft for example, includes a plurality of heater units (1, 12, 14) electrically coupled together by respective extension cables (3) and electrical coupling elements (42). Each heater unit comprises one or more heating conductor bands, tapes or strips (2, 21, 22) connected to respective connection modules (5, 51, 52, 52', 53) at the ends thereof. The connection modules may connect together several heater bands within one heater unit, and may connect the terminal ends of the heater bands of one heater unit to the extension cables by which several respective heater units may be connected together. Each connection module includes a housing (6) enclosing an inner chamber (61) therein, and at least one electrical connector element (7) such as a crimpable connector fixed within the housing (6). The respective conductors of the heater bands (2) and of the extension cables (3) extend into the housing through lead-in openings (64) and are connected together within the housing (6) by the respective connector elements (7). A complete and reliable seal against moisture penetration is achieved by injecting a sealing compound (19) into a fill hole through the housing wall, so that the inner chamber (61) of the housing (6) is completely filled with the sealing compound (19). The sealing effect eliminates capillary action even when subjected to vibrations, shock, temperature variations, and low pressure conditions. The assembly of the connection modules is simple and economical.
摘要翻译：一种适于防止飞行器中的水线冻结的互连加热导体的系统包括通过相应的延长电缆（3）和电耦合元件（42）电耦合在一起的多个加热器单元（1,12,14）。每个加热器单元包括在其端部处连接到相应连接模块（5,51,52,52'，53）的一个或多个加热导体带，带或条（2,21,22）。连接模块可以将一个加热器单元内的几个加热器带连接在一起，并且可以将一个加热器单元的加热器带的末端连接到可以连接在一起的多个加热器单元的延长电缆。每个连接模块包括在其中包围内室（61）的壳体（6）和固定在壳体（6）内的至少一个电连接器元件（诸如可卷曲连接器）。加热器带（2）和延长电缆（3）的相应导体通过引入开口（64）延伸到壳体中，并且通过相应的连接器元件（7）在壳体（6）内连接在一起。通过将密封化合物（19）通过壳体壁注入填充孔中来实现完全可靠的防止湿气渗透的密封，使得壳体（6）的内室（61）完全被密封化合物（19）填充）。即使经受振动，冲击，温度变化和低压条件，密封效果也能消除毛细管作用。连接模块的组装简单经济。

摘要： A godet in which the areas of the magnetic return jacket reaching to the inside periphery of the godet jacket are formed by separate intermediate rings made from magnetically active material, which are placed on front and back ends of the short-circuiting rings and between the short-circuiting rings. Inside surfaces of the short-circuiting rings and intermediate rings, together, form the inside periphery of godet jacket, and the godet jacket has an outside jacket disposed coaxially outside of the magnetic return jacket. Open annular channels are formed between the magnetic return jacket and the outside jacket as well as between the magnetic return jacket and the short-circuiting rings or intermediate rings. The annular channels are connected to one another on both ends by crosswise channels, and the annular channels and crosswise channels are filled with an electrically highly conductive, magnetically inactive liquid metal. The primary winding of the heater is supplied with power in phase displacement so that a field traveling in the axial direction results.
