• Control in the refining process
  intermediate temperatures (40C) gave the highest tensile. Much of the energy used in refining is released as an increase in the temperature, but over a range of energy inputs up to 300 net kWhr/t temperature still remains below 50C. 3.6 Drainage rate and freeness control Figure 6 Control of refining...
• One Step Ahead
  for downforce tracks and one for superspeedways. For the new Pontiac, Gibbs built the downforce car and MBV tackled the speedway version. Cars built for downforce race on short or intermediate tracks where handling is critical and drag isn’t as big a factor because cars run at full horsepower. NASCAR...
• PAT: Gateway to Advanced Control for Operational Excellence
  intermediate calculations, we developed an expert system that would list possible suggestions for example, relieving specific constraints or changing the problem setup. This guides the operator in handling special problems, but can require extensive custom code for each little solution...

  of ways to yield intermediate products, such as ethanol, styrene, ethyl. chloride, butadiene, and methanol. These intermediates are used for the manufacture of plastics, synthetic rub-. bers, synthetic fibers, and other products. There are many advantages to making the first conversion...
• Carpenter Technology outlines how high-tech melting creates high-performance metal alloys
  that must have clean microstructures. Fastener grades can also be processed with ESR. The technique is sometimes used as an intermediate step in producing alloys for aerospace components. VAR is another secondary process for refining metal that was previously melted or remelted into a consumable...

  , and usually unstable in air. Thus experiments may have to be carried out at low temperatures, and in an 'inert' atmosphere such as nitrogen or argon. Chemists have further difficulty, partly because when the chemicals react there are intermediate or 'transition' states -- inbetween stages as a molecule...
