Windows, arrange

The derrick window arrangement types A, C, D, and E, shown in Figure 4-2, shall be interchangeable. The sizes and general dimensions of the V window opening and drawworks window opening are given in Tables 4-1 and 4-2. 

The in-line window arrangement ensures that the fluids in the chamber can be seen very clearly and can be illuminated with normal or polarised light if desired. The disappearance of the meniscus at the surface of the liquid carbon dioxide as it becomes a supercritical state is very easy to see with this instrument. In spite of its rugged construction, the vessel is pressurised and depressurised slowly in use to prevent undue stress on the components. 

The primary x-ray source is usually a sealed tube with a Rh anode. The tube usually has an end window so that the sample is as close to the anode as possible. This arrangement ensures that the surface of the sample is irradiated with a beam with nearly uniform intensity. 

First, it was verified that the building ventilation geometry was to API Standards (no significant internal resistance and inlet and outlet openings vertically separated and on opposite walls). The building had many windows on both sides and 3-ft wide louvers at the roof peak. So the inlets were on both sides and the outlet at the top middle. This arrangement was judged adequate. 

In the latter the surfactant monolayer (in oil and water mixture) or bilayer (in water only) forms a periodic surface. A periodic surface is one that repeats itself under a unit translation in one, two, or three coordinate directions similarly to the periodic arrangement of atoms in regular crystals. It is still not clear, however, whether the transition between the bicontinuous microemulsion and the ordered bicontinuous cubic phases occurs in nature. When the volume fractions of oil and water are equal, one finds the cubic phases in a narrow window of surfactant concentration around 0.5 weight fraction. However, it is not known whether these phases are bicontinuous. No experimental evidence has been published that there exist bicontinuous cubic phases with the ordered surfactant monolayer, rather than bilayer, forming the periodic surface. 

Double-glazed windows work on the same principle. It is important to avoid the coincidence of the resonant frequencies of the two elements, and hence it is usual to arrange for the glazing panels to have different thickness (and hence a different resonant frequency). This is not necessary if one element is sub-divided by glazing bars to give different-size panes to its opposing element. 

Across the top there is a menu bar with the usual Windows-type pull-down menus arranged from left to right in the order Files, Data Selection, Data Manipulation, Extras/Options, Output, or similar. Those options that are allowed or make sense in a given context are activated. Requests for numerical input make use of the standard Windows-type gray box with the question that is to be answered, the white area into which the data is written, and the appropriate confirmatory Yes/No/Cancel buttons. 

Most recently, they have developed" a cell configuration for the study of modified electrodes that employs, as a working electrode, colloidal graphite deposited onto kapton tape (typically employed as a window material). Such an arrangement minimizes attenuation due to the electrolyte solution.
