    • A filter element includes a first, outer tubular construction of filter media defining a first open filter interior; a second, inner tuber construction of filter media defining a second open filter interior; the second construction of filter media being located within the first open filter interior and being radially spaced from the first construction of filter media; and the second open filter interior defines an unfiltered fluid channel. A plastic inner liner is within the first open filter interior to support the first construction of filter media. A plastic outer liner is within the first open filter interior to support the second construction of filter media. A filtered fluid channel is defined between the inner liner and the outer liner. A brace arrangement is between the first and second tubular constructions. The brace arrangement can include a spring, a plurality of gussets, or a solid spacer.
    • 过滤元件包括限定第一开放过滤器内部的过滤介质的第一外部管状结构; 第二内部块状结构的过滤介质限定第二开放过滤器内部; 过滤介质的第二结构位于第一开放过滤器内部并且与过滤介质的第一结构径向间隔开; 并且第二开放过滤器内部限定未过滤的流体通道。 塑料内衬在第一开放过滤器内部,以支持过滤介质的第一结构。 塑料外层衬垫位于第一开放过滤器内部,以支持过滤介质的第二结构。 过滤的流体通道限定在内衬和外衬套之间。 支架装置位于第一和第二管状结构之间。 支架装置可以包括弹簧,多个角撑板或固体间隔件。

    • A system that allows the remote measurement of the size, geometry, pitch and orientation of the roof sections of a building and then uses the information to provide an estimate to repair or replace the roof, or to install equipment thereon. The system includes an aerial image file database that shows aerial images of buildings in a designated area according to address. The slope and orientation images are typically oblique perspective views and top plan views of the buildings in the area. The system also includes an image analysis and calibration feature that enables the viewer to closely estimate the size, geometry and orientation of the building's roof sections. The information can then be used to prepare a cost estimate for the repair or replacement of the roof or installation of roof equipment. By simply inputting the potential customer's address, the company is able to determine the size, geometry, pitch and orientation of the roof sections of the building at that address, and then quickly provide an accurate estimate to the customer.
    • 允许远程测量建筑物屋顶部分的尺寸,几何形状,俯仰和方向的系统,然后使用该信息来提供对屋顶的修理或更换或在其上安装设备的估计。 该系统包括一个航空图像文件数据库,根据地址显示指定区域内的建筑物的空中图像。 倾斜和定向图像通常是该区域的建筑物的倾斜透视图和俯视图。 该系统还包括图像分析和校准功能,使得观看者可以仔细估计建筑物屋顶部分的尺寸,几何形状和方向。 然后可以使用这些信息来准备屋顶设备的屋顶或安装的修理或更换的成本估算。 通过简单地输入潜在客户的地址,公司能够确定该地址的建筑物屋顶部分的尺寸,几何形状,倾斜度和方向,然后快速为客户提供准确的估计。
