Window design

No use trying to concentrate Frost bit the window, designing it into two uneven panes. Winter in Washington was usually a comfortable prospect, after the miserably humid summers but this time I would feel alone even if comfortable. The man who had introduced me to I.G. Farbenindustrie would not be there. He was Bernard Bernstein, Assistant General Counsel of the Treasury De-...

The window design required the penetration test piece to be constructed with a rectangular cross section rather than the typical circular ACR configuration. To duplicate expected ACR fluid-flow parameters, the rectangular dimensions were sized to produce the area ratios and Mach numbers consistent with the originally proposed prototype ACR. A reactor cylinder was not required since gas yields were not measured during this test. 

Notice that these exercises have the three-part window design described earlier, with the top portion reserved for instructions or feedback, the middle containing the current story or problem, and the lowermost reserved for student response. For the mapping exercises, the lower portion of the window contains a diagram. To make a response, the student selects a part of the story or problem text and places it in the diagram. (Exact technical details of response and feedback are described later in this chapter.)... 

Step 2 With the cursor in the spectrum window click the right mouse button. The button panel changes to the layout shown on the left and at the same time a cursor appears at the top of the spectrum window designating the reference peak to be used for the zero-order phase adjustment. By default the cursor is set on the maximum signal (Big Point), clicking the Cursor button allows the reference peak to be set manually. Click on the Correct the Phase button to continue with the zero-order phase correction. 

The pharmacokinetic window design has many variants. One variant is where each subject is sampled twice on each visit. The subject comes to the clinic, has a blood sample drawn at predose, the next dose is taken, the subject remains at the clinic for some time, and then a second sample is collected after a period of time has expired. The disadvantage of this approach is that it requires the subject to remain at the clinic, which places an extra burden both on the subject and on the site in collecting the sample. The advantage of this design is that the quality of the dosing times and sample collection... 

The optical measurement is made near the edge of a sample cuvette the cuvette is close to the pressure window and the high-pressure window is itself reduced to a minimum thickness. Instead of using 1 cm of sapphire, 1 mm of steel makes a good window , if this 1 mm can be supported. An effective solution has been described recently. A 17 mm thick steel disc has a honeycomb pattern of holes drilled to within 1 mm of the opposite face. This rigid structure increases the electron-beam intensity tenfold at the sample. This window design is shown in Fig. 6.13. 

A stainless steel precipitation vessel P, possibly with a glass window, designed to work up to 120 bar. It has to be thermostatted by either a jacket, or a heating tape. It must be equipped with a safety system (rupture disk, check valve) and possibly a magnetic stirrer. 

Figure 4.12 shows typical detection efficiency as a function of wavelength. Efficiency attenuation at long wavelengths is controlled by entrance window materials and varies depending on window design. At short wavelengths, gas type, gas density, and thickness of the sensitive volume determine the transparency of the detector to x-rays. 

There are two types of photomultipliers - end window and side window. The end-window design is illustrated in Figure 4. 

From the Search Form window design your search profile using text, structure or text/structure searching. Once yonr search has been performed the resultant hits are listed alphabetically by chemical name in the Hit List screen. Clicking on any one of the hits in the hit list screen will result in that entry being displayed in the Entry Display screen (Fig. 4). 

The joining of the window through bonding enables new window designs with reduced frame cross sections and higher overall stiffness, which prevents the window from unwanted bending. 

The design of photomultipliers varies depending upon what they are to measure. For scintillation gamma-ray measurements, they are always of an end-window design with the photocathode deposited on the inside of the face of the tube. The whole structure is enclosed within an evacuated glass envelope and connections made via a multipin plug at the anode end.

Display windows Designed to provide very good visibility for timers and electronic displays, require good transparency combined with good scratch resistance. PC resin can therefore be used.
