Some empirical equations to predict cyclone pressure drop have been proposed (165,166). One (166) rehably predicts pressure drop under clean air flow for a cyclone having the API model dimensions. Somewhat surprisingly, pressure drop decreases with increasing dust loading. One reasonable explanation for this phenomenon is that dust particles approaching the cyclone wall break up the boundary layer film (much like spoiler knobs on an airplane wing) and reduce drag forces. 

By employing additives to improve interfacial adhesion and the cohesive strength of the mbber phase, natural mbber can compete with ethylene—propylene mbbers as an impact modifier for polypropylene. These hard grades, containing between 15 and 25% natural mbber, have the potential for use in the automotive and domestic markets, eg, in bumpers, spoilers, grilles, electrical connectors, and floor tiles.

For the composite spoiler design, the bottom is a variable-thickness skin on one side in Figure 1-33, but with composite materials that construction is not difficult. We do not have to chem-mill a composite material to change its thickness. All we do is stop building up the material in layers in the middle, but continue to build it up at the sides. That s a very natural process for composite materials and does not involve a costly machining operation. Instead of machined extruded stiffeners, a honeycomb core is placed on the inside of the laminae. That honeycomb... 

In the automobile and electronic industries, large amounts of pressed parts from SMC or BMC are used, for example, for bumpers, trunk covers, and spoilers. 

Deck lids can take the same parts consolidation path as hoods. The deck lid, inner, with spoiler and the deck lid, outer, could be combined into a one-piece self-reinforced deck lid.

Two key parameters have been found to determine the ultimate eapabili-ties of the MOEMS-based MOS contrast and spectral photometric variation (SPV). Contrast is dehned as the total amount of non-selected flux of light passing through the multi-slit device a contrast requirement of 2000 has been established in order to avoid pollution of the spectra by strong sources (spoilers) and sky background. The SPV is the unpredictable photometric variation due to the random position of the sources on the PMSM grid SPV requirement has been fixed to <10%. 

The isolation of a particular microorganism fiem a markedly spoiled product does not necessarily mean that it was the initiator of the attack. It could be a secondaiy opportunist contaminant which has overgrown the primary spoilage organism once the physico-chemical properties had been favourably modified by the primary spoiler.

A new thermoformable grade of polyamide from Bayer can be extruded into sheets and then thermoformed to deep draw ratios, allowing the production of spoilers for BMW.
