    • A dielectric loaded cavity filter having a housing and a cover and defining at least two adjacent cavities having respective dielectric resonators mounted therein and separated by a transverse partition defining a coupling window in the housing. In one form, the coupling window has two spaced opposing sidewalls confronting each other, and vertically offset shoulders intermediate their length. A conductive coupling strip is secured to the shoulder of one sidewall and extends across the coupling window and over the shoulder of the other sidewall. A tuning screw is secured by threading to the housing and has an outer free end accessible from the exterior of the filter, and an internal end disposed adjacent the coupling strip, whereby when the tuning screw is rotated, the internal end of the screw moves toward and away from the coupling strip in a direction perpendicular to the cover for tuning without requiring access to the coupling strip. In another form, no coupling strip is present and the tuning screw inner end confronts a shoulder of a sidewall.
    • 一种电介质负载型腔体滤波器,具有壳体和盖子,并且限定了至少两个相邻的空腔,该腔体具有安装在其中的相应的介电谐振器,并由在壳体中限定耦合窗口的横向隔板隔开。 在一种形式中,联接窗口具有彼此面对的两个间隔开的相对侧壁,并且在其长度之间垂直偏移的肩部。 导电耦合条被固定到一个侧壁的肩部并且延伸穿过耦合窗口并在另一个侧壁的肩部上方。 调谐螺钉通过螺纹固定到壳体上并且具有可从过滤器的外部接近的外部自由端和邻近连接条设置的内部端部,由此当调谐螺杆旋转时,螺钉的内部端部向着 并且在垂直于盖子的方向上离开连接条,用于调谐而不需要进入联接条。 在另一种形式中,不存在耦合条,并且调谐螺钉内端面对侧壁的肩部。

    • A foundation structure comprises a plurality of light metal parts which assemble and secure in place prior to placement of foundation in situ concrete. Assemblage is supported by coarsely threaded rods which screw directly into earth and attach to parts by various methods. Some parts remain in place as permanent supporting members for superimposed structure. Others, which generally form surfaces of foundation concrete, subsequently relocate to become either similar permanent structural members, or inventory for subsequent projects. Use of a computer aided design program assists in optimal configuration of parts, and creates a list of parts with necessary cut and piecemark information for automated fabrication of any particular length parts. This information, along with a computer produced schematic plan, allows use of parts as collocation elements which define a distinct foundation design by simple field assembly. Variations in assemblage of parts accommodate requirements of site, user needs, and materials of subsequent structure. Specific versions offer an integral joist floor structure, a free standing wall, or a concrete slab on grade. Interface with subsequently superimposed walls is specific to those of either framed members, or concrete type materials.
    • 基础结构包括多个轻金属部件,在放置基础现场混凝土之前组装并固定就位。 组合杆由粗螺纹杆支撑,螺杆直接拧入地面并通过各种方法附着在零件上。 一些部件作为叠加结构的永久性支撑构件保持原位。 其他通常形成基础混凝土表面的其他材料随后迁移成为类似的永久性结构构件,或用于后续项目的库存。 使用计算机辅助设计程序有助于零件的最佳配置,并创建一个具有必要的切割和分片信息的零件列表,用于自动化制造任何特定长度的零件。 该信息以及计算机生成的原理图计划允许使用零件作为搭配元件,通过简单的现场组装来定义不同的基础设计。 部件组合的变化可以满足现场要求,用户需求和后续结构的材料。 具体型号提供一体式托梁地板结构,独立的立式墙或一级的混凝土板。 与随后叠加的墙壁的接口与框架构件或混凝土类型材料的界面相关。
