Panel level data processing

A data acquisition system was attached to the control panel of the extruder in parallel with the existing controllers. Barrel temperatures, discharge pressure, motor current, and several downstream sensors were recorded at a frequency of once per second. The sensors downstream from the extruder were showing that the downstream part of the process was not contributing a significant level of variation to the profile dimensions. The rate was measured at 53 kg/h for a screw speed of... 

Figure 2.1 shows the normal modes for the relaxation of para-H2 by helium at 500 K, calculated from the best available theoretical cross-section data [81.M2]. The left-hand panel shows an initial distribution (in this case, for 3(X) K), and the right-hand panel is the equilibrium distribution at 5(X)K, (Mo),=(So)((So)< the individual populations are displayed horizontally. The other modes are displayed in order of their rate constants, with the fastest ones to the left the elements of each mode are normalised to unity, but the overall sign is arbitrary. The fastest mode M9 corresponds to the transfer of molecules between J=0 and J=2 of i =0 and the next one Mg is the analogous process for p=l. In the relaxation shown here, there is a rather small flux for Mg, given by equation (2.19) physically, this is because this mode does not connect the initial distribution with the final distribution. Then come another pair of processes connecting the J=0, 2, and 4 levels of y = l, and then of r=2, followed by a series of other rotational processes of t)=0 involving... 

Dow Chemical claims a patent on a blend [11] with a decreased tendency toward delamination, which exhibits a desirable balance of properties, a high level of impact resistance, solvent resistance, and processability. The product can be blown into films, spun into fibers, extruded into sheets, formed into multilayer laminates, and molded into any desired shape and can be used in data storage apparatus, appliance and instrument housings, motor vehicle body panels, and other parts and components for use in electrical, automotive, and electronic industries.
