Highspeed application

Polyolefins, other synthetic polymers, and water-soluble macromolecules have been investigated in highspeed SEC systems. High-speed SEC can be a major time saver in two-dimensional chromatography applications, which require about 10 hr analysis time for cross-fractionation. This can be reduced by a factor of 10, to about 1 hr, which makes it much more interesting for many laboratories. Details on these and additional highspeed applications can be found in Ref. [4]. [Pg.778]

These anaerobic adhesives fill all surface irregularities and tolerance gaps and effectively seal clearances up to 0.76 mm. They can be applied by highspeed applications in moving production lines. The cured film has excellent chemical resistance to most liquids and gases within an operating temperature range of — 54°C to 232°C. [Pg.92]

Silicon devices covered with insulating layers of thermal oxide and CVD nitride have been shown to suffer from breakdown problems which limit the applicable voltages [34]. For that reason, very few experimental studies on highspeed CE (requiring high field strengths) have appeared in the literature where silicon substrates were used, in contrast to its successful use in other separation techniques as discussed in Sects. 4 and 5. [Pg.58]

It is truly remarkable that catalysts can function so well in the exhaust of the modem highspeed vehicle. This fact has raised confidence in industry to use different monolithic (ceramic and metal) structures as supports for catalysts for other environmental applications such as diesel exhausts, power and chemical plants, restaurants, and even on widebody aircraft. [Pg.295]

The application of the chemical schemes to atmospheric phenomena requires a diffusion formulation that reflects time-dependence and spatial variability of meteorological conditions. An attempt has been made to keep the mathematical description near the level of detail and precision of the observational data. This has resulted in a Lagrangian air parcel formulation with finite-rate vertical diffusion. The approach avoids the artificial numerical diffusion because it uses natural (or intrinsic) coordinates that are aligned with fluid motion. This allows us simultaneously to include upward dispersion and chemical change. Figure 1 schematically illustrates the main features of the formulation. Highspeed memory requirements are limited by allowing sequential point-by-point output of the history of the air parcel. [Pg.107]

Typically, polyester wire insulation is rated as Class 155. This insulation is frequently overcoated with nylon to provide a surface with good lubricity which is needed for application in highspeed coil winding. Magnet wire with this type of insulation is used in the manufacture of electric motors for nonhermetic applications. [Pg.522]

An alternative stirrer, the pitched-blade turbine is especially suited for highspeed liquid-solid applications, where the use of baffles might be impractical. The fluid can be directed up or down, depending on the direction of the pitch of the blades. The pitched-blade turbine is more flow-efficient than radial style impellers. Designs incorporate three and four blades at 45 ° or 30 ° pitch. The pitched blade is used when a balance of flow and shear (turbulence) is required. [Pg.54]

It is now recognized that yet another situation pertains to many compounds of the actinides. This may be termed the intermediate-field case, for which spin-orbit c crystal field electronic repulsion. Obviously this situation is more complex theoretically, in the sense that none of the usual perturbation-type calculations are applicable here. Since the advent of highspeed digital computers, however, this need not be a serious limitation. [Pg.353]
