Engineers files

Files are used to perform a wide variety of tasks, from simple removal of sharp edges to producing intricate shapes where the use of a machine is impracticable. They can be obtained in a variety of shapes and in lengths from 150 mm to 350 mm. When a file has a single series of teeth cut across its face it is known as single-cut fAe, and with two sets of teeth cut across its face it is known as double-cut fAe, Fig. 2.1. 

Files are identified either by their general shape - i.e. hand, flat or pUlar - or by their cross-section - i.e. square, three-square, round, half-round or knife - Fig. 2.2.

This file has the same section as a hand file but of a thinner section. It is used for narrow slots and keyways. 

The flat file is also for general use, typically on flat surfaces. It is rectangular in cross-section and tapers in both width and thickness for approximately the last third of its length towards the point. Both faces are double-cut and both edges single-cut. The tapers in width and thickness enable this file to be used in slots which are narrower than its full width and thickness and which require filing on length and width.

The output of the usability activities form the usability engineering file and the standard suggests that this forms part of the wider risk management file. The material is typically subject to audit by the Notified Body certifying the medical device.

Then in 1970 Esso research and engineering filed [3] a series of patents over several years on the cobalt oxide/molybdenum oxide/caesium acetate supported alumina catalyst. This catalyst henceforth is called the Aldridge catalyst in tribute to its principal discoverer Clyde L. Aldridge at Esso. Acmally these patents describe a family of catalysts. Aldridge believes that the catalyst should have the following components to be active at as low as temperatures below 140 °C.

The Chemical Abstracts (CA) File is the main abstracting and indexing service for biochemistry, chemistry, and chemical engineering. 

Several of the reactor physics parameters are both measurable and calculable from more fundamental properties such as the energy-dependent neutron cross sections and atom number densities. An extensive database. Evaluated Nuclear Data Files (ENDF), has been maintained over several decades. There is an interplay between theory and experiment to guide design of a reactor, as in other engineering systems.

QRA practitioners can use to satisfy some QRA objectives. Also, the American Institute of Chemical Engineers (AIChE) has sponsored a project to expand and improve the quality of component failure data for chemical industry use. And many process facilities have considerable equipment operating experience in maintenance files, operating logs, and the minds of operators and maintenance personnel. These data can be collected and combined with industrywide data to help achieve reasonable QRA objectives. However, care must be exercised to select data most representative of your specific system from the wide range available from various sources. Even data from your own plant may have to be modified (sometimes by a factor of 10 or more) to reflect your plant s current operating environment and maintenance practices. 

That the mechanic has the drawings available at the moment of installation. Often times, the engineer stores the drawings in a file so they won t get lost or dirty. For innumerable reasons, the mechanic rarely has a set of drawings available at the installation.

The NPRDS is an industry-wide system for monitoring the performance of selected systems and components at U.S. commercial nuclear power plants. Information in NPRDS is derived from a standardized format input report prepared by U.S. nuclear plant licensees. The plants are as)ced to submit failure reports on catastrophic events and degraded failures within the defined reportable scope reporting of incipient events is optional. Command faults are not reportable unless they malce an entire system unavailable. In addition, the plants are as)ced to file component engineering reports on all components within the selected systems and reportable scope. These reports contain detailed design data, operating characteristics, and performance data on the selected systems and components (over 3000 components, from approximately 30 systems, per unit). The selected systems are primarily safety systems. 

Although maintenance systems contain some of this information, engineering, purchasing, and operating department records may be required to find the remainder. Also, equipment maintenance records may be in several file locations since they are usually organized by components and component modules that may differ from equipment boundaries established for risk analysis.
