Blue smoke

The Conradson test (ASTM D-189) measures carbon residue by evaporative and destructive distillation. The sample is placed in a preweighed sample dish. The sample is heated, using a gas burner, until vapor ceases to burn and no blue smoke is observed. After cooling, the sample dish is reweighed to calculate the percent carbon residue. The test, though popular, is not a good measure of the cokeforming tendency of FCC feed because it indicates thermal, rather than catalytic, coke. In addition, the test is labor intensive and is usually not reproducible, and the procedure tends to be subjective. 

Restaurants in particular responded in kind, increasing their emphasis—with expanding floor space and atmospheric amenity— on bar areas and people who came for cocktails, not dining. As Danny Meyer, the popular New York restaurateur who opened Union Square Cafe in 1985, said of the current situation, It s a cocktail generation. It s fun, it s sexy. It s more fun than a glass of Chardonnay. Fifty percent of the customers at Blue Smoke, Mr. Meyer s newest restaurant and bar, were there to drink, not to dine, he said.

Blue Smoke, a barbecue restaurant on East 28th Street, is one of the M.B.A. barns on the Park Avenue South strip, down the block from the Park Avenue Country Club and Houston s, across the avenue. 

On Thursday night, Blue Smoke was crowded three deep with young(ish) money-makers drinking. If you ve ever wondered who s moving into all those new luxury-rental buildings or driving the average price of a one-bedroom apartment past 500,000 in New York—and you re not one of them—you can drink with them at Blue Smoke. 

The bar s televisions were tuned to ESPN, where a football player, in an interview, was dealing with his finer emotions. Aretha Franklin, Marvin Gaye and all the other artists who, historically, form the soundtrack of a bar scene in a college town or a home-game weekend fraternity party, played on Blue Smoke s sound sys-... 

At UVa.,Thursday only existed as a prelude to Friday—any bar would have pumped your chest with music and the drinking was calisthenic. You had twenty-four short hours before you had to do it seriously. There were a few too many A students at the bar at Blue Smoke. 

An even greater pitfall into which many young process control engineers fall, particularly in recent years, is to get so involved in the fancy computer control hardware that is now available that they lose sight of the process control objectives. All the beautifiil CRT displays and the blue smoke and mirrors that computer control salespersons are notorious for using to sell hardware and software can easily seduce the unsuspecting control engineer. Keep in mind your main objective to come up with an effective control system. How you implement it, in a sophisticated computer or in simple pneumatic instruments, is of much less importance. 

The Nyquist stability criterion is, on the surface, quite remarkable. We are able to deduce something about the stability of the closedloop system by making a frequency response plot of the openloop system And the encirclement of the mystical, magical (— 1, 0) point somehow tells us that the system is closedloop unstable. This all looks like blue smoke and mirrors However, as we will prove below, it all goes back to finding out if there are any roots of the closedloop characteristic equation in the RHP. 

But keep in mind that from a purely technical control performance standpoint, an analog controller can do a better job than a sampled-data controller in most applications. The process of sampling results in some loss of information we don t know what is going on in between the sampling periods. Thus there is an inherent degradation of dynamic performance that no amount of high-tech sales hype and blue smoke can change. 

One effect of valve sleeve, piston ring, and cylinder wall wear is leakage of lubricating oil into the combustion chamber. When lubricating oil accumulates in the combustion chamber and bums with fuel, the exhaust smoke appears blue in color. Wear due to abrasion or corrosion has the same effect. At times, unbumed fuel can also appear as blue smoke if fuel droplets are finely dispersed in the exhaust. Blue smoke is a symptom of a mechanical problem rather than a fuel performance problem.

Indigo pure is a stable dye, which gives a blackish blue smoke, but when the burning temperature of the smoke composition is too high, it is decomposed to generate yellow grey smoke.
