Distribution Disk

The distribution disk located at the Butterworth-Heinemann website http //www.bh.com/ contains the following software for use on an IBM or IBM-clone personal computer operating in DOvS, Windows 3.1 or Windows 95. The programs are small, operate in the DOS mode with minimal system requirements. It is recommended that a directory (folder) be constructed on your hard drive and copy them to this directory. No guarantees are made use them if you find them useful. Thev are

The distribution disk with this book includes a folder entitled BNLDATA which contains the file bnlgener.xls, a spreadsheet in EXCEL format. It is a collection of failure rate data drawn from many sources. The file refem.txt contains the references to the table s data. There are 1,311 data entries many cite different estimates by different organizations for the failure rate of the same... 

The disk centrifuge is an excellent instrument for determining particle size distributions in the size range from several micrometers to somewhat below 0.1 ym. For broad or especially multimodal size distributions, disk centrifugation is, overall, probably superior to any other sizing method for the aforementioned range. 

Hic purity partially sintered nickel sheets were obtained from ERC (Electric Research Ciorp.). The porosity of these sheets varied firom 60% to 70%. The proprietary nature of these materials prohibits any release of the pore size distribution. Disks with a thickness of 30 mils and a diameter of 11/4" were cut from this material. This disks were soaked in 1 molar liOH, dried at 100X1, and oxidized in room air at 650 C for at least 8 hours to form a lithiated NiO stmcture. Gravimetric analysis of these electrodes showed that they were greater than 98% converted to NiO. 

Two identification examples will be discussed in this section. The parametric model identification is done in MATEAB using the identification toolbox. Let us assume that you have copied the files on your distribution disk to the directory C MatlabR14 work directory. Start Matlab by double clicking the Matlab icon. You are now ready to run the identification examples. 

In order to define the extent of emissions from automotive brakes and clutches, a study was carried out in which specially designed wear debris collectors were built for the dmm brake, the disk brake, and the clutch of a popular U.S. vehicle (1). The vehicle was driven through various test cycles to determine the extent and type of brake emissions generated under all driving conditions. Typical original equipment and aftermarket friction materials were evaluated. Brake relines were made to simulate consumer practices. The wear debris was analyzed by a combination of optical and electron microscopy to ascertain the asbestos content and its particle size distribution. It was found that more than 99.7% of the asbestos was converted to a nonfibrous form and... 

Tilting-Disk Check Valves These valves (Fig. 10-160) may be installed in a horizontal line or in hnes in which the flow is vertically upward. The pivot point is located so that the distribution of pressure in the fluid handled speeds the closing but arrests slamming. Compared with swing checkvalves of the same size, pressure drop is less at low velocities but greater at high velocities.
