Caterpillar's profits are up.  The company reports a record 15-point seven billion dollars in sales from July through September.  That's a 30-percent increase over 2010's third quarter report.  The increased revenue comes even as the company took on more overhead.  They've hired more than 19-thousand additional workers since this time last year.  According to the company's economic outlook, they expect to see continued growth for the rest of this year and into 2012.
