Inspection window

Metal enclosed type This type of assembly is completely enclosed on all sides by sheet metal except for the operating handles, knobs, instruments and inspection windows. The more conventional of them in use may be classified as follows,... 

The cross-sections of the conductor and the enclosure arc then checked for their adequacy to dissipate the heat generated. The cross-section is then adjusted suitably by permuialions and combinations to arrive at the most appropriate size, keeping in mind the available extruded sections, accounting for all such factors that may affect the rating or the fatilt level of the enclosure and the conductor, such as tap-offs, which are subjected to a cumulative faull level, openings in the conductor for heat dissipation or the enclosure for inspection windows that can infhience their ratings. A calculation in Example 31.1 will clarify the procedure to establish the size of the... 

Add a suitable margin in the conductor s cross-section to account for the opening considered to dissipate the inside heat. Similarly, add a suitable margin in the enclosure s cross-section to account for the inspection windows.

By inspection windows and use of a pyrometer, visual inspection of the catalyst and temperature monitoring on-site in a contactless manner were performed. It turned out that a glowing, homogeneous texture occurs at catalyst temperatures between 900 and 1200 °C, GHSV values up to 10 h and pressures less than 1 MPa [3]. This is an indication of the absence of soot deposits. At lower temperatures or... 

GP 11] [R 19] For an autothermal reactor, i.e. a device with neither internal nor external heat transfer, steep temperature profiles along the flow axis were found [9]. Via an inspection window, glowing of the front zone of the wire reactor was observed, indicating complete conversion within a few mm reaction passages. The... 

The disadvantage of the two-phase contacting principle is related to the technical expenditure of realizing phase separation throughout the complete reactor passage. Special measures have to be taken to prevent phase inter-mixing. Also, this has to be controlled during the process. Hence inspection windows are essential (for the first prototype they may be eliminated later). 

Internal heat exchange is realized by heat conduction from the microstructured reaction zone to a mini channel heat exchanger, positioned in the rear of the reaction zone [1,3,4], The falling film micro reactor can be equipped, additionally, with an inspection window. This allows a visually check of the quality of film formation and identification of flow misdistribution. Furthermore, photochemical gas/liquid contacting can be carried out, given transparency of the window material for the band range of interest [6], In some cases an inspection window made of silicon was used to allow observation of temperature changes caused by chemical reactions or physical interactions by an IR camera [4, 5].

The micro bubble column comprises internal cooling via heat conduction from the reaction zone to a mini channel heat exchanger [3, 9, 10], Either two such heat exchange plates can encompass the reaction plate, or only one. In the latter case, the free position is occupied by an inspection window which allows direct observation of the quality of the flow patterns.

These notified bodies have introduced a type of certificate without any legal status the component certificate, which is marked by a U following the certificate number. This document acts as a working instrument for a simpler handling of components like conductor bushings, terminal blocks or inspection windows. The notified body issuing such a component certificate herewith declares the conformity with the relevant Harmonized European Norm and the relevant type tests. Other notified bodies accept this document without asking for renewed type tests. In this way, components can be handled in a very efficient...

At the present moment the European regulatory authorities tend towards the situation where a company s compliance history and the fact that the specific facility is within a two-year satisfactory inspection window, to determine... 

Half-cell potentials cannot be correlated directly with the corrosion rate of the rebars. By excavating suitable inspection windows in the transition areas between very negative (active) and passive regions, the intensity of corrosion attack can be determined, and a correlation between potential and corrosion state can be established. This is valid only for the specific structure investigated.

An essential role in the implementation of GCE in MSU is played by the Moscow University Supercritical Innovation Center, MUSIC (Head, Prof. V. Lunin Scientific Sectetary, Prof. S. Vatsadze). The main goal of MUSIC is the training of high-quality specialists in the use of supercritical fluids (ScF) for research laboratories, performing the study of fundamentals and developing new ScF technologies. The instrumentation of MUSIC includes a unique mobile ScF set with a high-pressure cell equipped with an inspection window, four stationary sets with a united control centre as well as a flow-type device.
