blowtube

On route, I vanished suddenly amid a furious flurry of leaves raised by a chap in a mask, who had been equipped with a motor-driven blowtube, which, with rare dexterity, he aimed at the thousands of leaves blocking the gutter.

Together with gradual improvements in the design and construction of smelters and tuyeres (durable ceramic blowtube tips) that we have documented over the span of some 500 years from the beginning of the Middle Sican (Shimada and Merkel 1991), we believe that, over the same time span, Sican metallurgists refined the nascent co-smelting technology inherited from their earlier Moche counterparts.

I sedated captured bobcats with an intramuscular injection of 8 mg of Telazol (Tiletamine HCl and Zolazepam Hcl, Fort Dodge Animal Health, Fort Dodge, Iowa) per kg of body weight via blowtube (Pneu-Dart, Williamsport, Pennsylvania).

A high pressure was found in the area adjacent to the blowtube, and a low pressure was found at the bottom of the corebox.

The probable cause for the pressure spike was the final filling of the core tooling due to the stopping of particle flow and "squeezing" of air as sand finally fills that section of core immediately under a blowtube. The modeling software calculates the pressure spikes to occur just as sand fills this region, quickly forcing air into the surrounding sand.
