General operating instructions

Over and above this, and particularly for the larger types with long rotor blades, airing the pump to atmospheric pressure while the impellers are rotating may be done only when observing exactly the rules given in the operating instructions. Under certain circumstances it is possible to operate turbomolecular pumps under exceptional conditions. 

The turbomolecular pump may, for example, be used unprotected inside magnetic fields if the magnetic induction at the surface of the pump casing does not exceed B = 3 10 T when radially impinging and B = 15 10 T at axial impingement. 

In a radioactive environment standard turbomolecular pumps can be used without hazard at dose rates of from 10 to 10 rad. If higher dose rates are encountered, then certain materials in the pump can be modified in order to withstand the greater loading. The electronic frequency converters in such cases are to be set up outside the radioactive areas since the semiconductors used inside them can tolerate a dose rate of only about 10 rad. The use of motor-driven frequency converters which can withstand up to 10 rad represents another option. 

Turbomolecular pumps and frequency converters are nearly maintenance-free. In the case of oil-lubricated pumps it is necessary to replace the bearing lubricant at certain intervals (between 1500 and 2500 hours in operation, depending on the type). This is not required in the case of grease-lubricated pumps (lifetime lubrication). If it should become necessary to clean the pump s turbine unit, then this can easily be done by the customer, observing the procedures described in the operating instructions.

These two trade organizations represent the views of their members, who between them manufacture some of the most common types of boiler found in general industrial and commercial applications. Their respective guidelines are very useful supplements to the detailed operating instructions provided by manufacturers. 

Each type of gas chromatograph has its own set of operating instructions, but general experimental conditions are appropriate for all instruments. Three important factors must always be considered when a GC analysis is to be completed (1) selection of the proper column (2) choice of temperatures for injector, oven, and detector and (3) adjustment of gas flow. Because hundreds of stationary phases are available, it is impossible to outline the characteristics of each. Selecting the stationary phase requires some knowledge of the nature of the sample to be analyzed. 

The apparatus used for the analysis is a continuous flow automated analytical instrument such as Technicon Autoanalyzer. Follow the manufacturer s instructions to set up the manifold and for general operation. 

The purpose of the present Section is twofold first to draw attention to the problems and ambiguities which have arisen in connection with the reporting of gas adsorption (physisorption) data and second to formulate proposals for the standardization of procedures and terminology which will lead to a generally accepted code of practice. It does not aim to provide detailed operational instructions or to give a comprehensive account of the theoretical aspects of physisorption. The determination of the surface area of supported metals is not dealt with here - despite the importance of this topic in the context of heterogeneous catalysis - since this necessarily involves chemisorption processes. 

All operators were trained in the site operations based on the U.S. EPA "Operation and Maintenance Manual for Precipitation Measurement Systems" (6) and the UAPSP "Field Operator Instruction Manual" (7). Daily site visits were generally made at about 9 00 a.m. local time to check the equipment and to remove any precipitation collected by the daily samplers. Weekly samples were removed on Monday from the Georgia and Vermont sites and on Tuesday at the Kansas site. If no event occurred for a week, the buckets were rinsed with deionized water to remove any dust that may have deposited and they were then reused. Analysis of the rinse water served as a dynamic blank. 

The procedure employed is thoroughly described in the instrument instructional manual. Thus, the following sections will deal only with the general operations and key operating parameters. 

The general features of a CW NMR spectrometer were described briefly in Exp. 32, and details about Fourier-transform NMR instruments are given in Exp. 43. For the spectrometer you are to use, more specific operating instructions will be provided by the instructor. Obtain several milliliters each of acetylacetone (CH3COCH2COCH3, M= 100.13, density = 0.98 gcm ) and ethyl acetoacetate(CH3CH20COCH2COCH3, M= 130.14, density = 1.03 g cm ). Prepare small volumes of two solvents and three solutions. 

Detailed operating instructions with references to general control procedures, if necessary. 

The nnclear station mnst be operated within the bonndaries set by the Operating Rules and other regnlations called Station Operating Instructions. These are formnlated to ensnre that all operations are carried ont within specified limits of the plant and the general reqnirements of the Operating Rules. 

The OSHA rules only generalize when it conies to inspection of heavy equipment, and they just cover safety equipment. The best source for inspection criteria is manufacturer s documentation. If that documentation does not have a comprehensive checklist, then you should assemble your own from the operating instructions and maintenance procedures. 

Thus, SOPs and WIs comprise general actions and operations that apply to groups of products or equipment. The preparation of a specific medicine will be described in a Preparation Instruction (PI) (see Sect. 33.4), while maintenance of equipment is laid down in Operating Instructions. SOPs are not suitable for the recording of control data. When the activities described in SOPs or instructions produce results or other data, for example results of audits and investigations or data... 

Although some differences in procedure and format exist between different plants, emergency response guidelines (ERGs) are generally written in a dual column format. The left column lists operator instructions (actions) and the right column defines actions to be taken if the expected result or response detailed in the left column is not obtained (RNO — response not obtained). 

According to astronauts normal flight manuals and operating instructions in a certain manned space mission, action items astronauts were to be carried out are detailed analyzed and generalized from the beginning to the spacecraft to return astronauts landing, 11 kinds of Meta-Operation includes clothing worn operation, open/close... 

Close liaison had to be maintained between the Office of the Chief, CWS, and the Office of Gvilian Defense in training and related activities. The general operating procedure was for the OCD to indicate what teaching was desirable, the War Department then determining how the instructional aim would be attained. Army relations with the OCD were handled through the... 

Becau.se agencies do not always specify how standards must be implemented, safety officials must transform regulations into practices and procedures (Document E) that can be applied across many different sites and conditions. At the local level, writers must develop ventilation plans, roof control plans, and general safety instructions that take into account differences in local conditions. In the mining industry, these plans must be approved at the District level before operators can proceed with their work. 

An operator is a mathematical instruction. For example, the operator d/dx is the instruction to differentiate once with respect to a . Matrices in general, and the matrix R of Chapter 6 in particular, are operators. The matrix R is an instruction to rotate a part of the operand matrix through a certain angle, 0 as in Eq. (6-62). 

Good measurement practices (GMPs) describe operations specific to a technique. In general, GMPs provide instructions for maintaining, calibrating, and using the equipment and instrumentation that form the basis for a specific technique. For example, a GMP for a titration describes how to calibrate a buret (if nec-...
