In addition to Strickland and Mourou, the Nobel committee announced the other half prize went to American scientist Arthur Ashkin for his work to create “optical tweezers,” a method of using lasers to cool atoms to a temperature where they can be studied individually. Based on work done at Bell Laboratories, the research included contributions by Rochester graduate Steven Chu ’70, who went on to win his own Nobel Prize in Physics in 1997.
Maximum sheet dimensions that can be accommodated on the fiber laser cutting machine’s table are 3.0 × 1.5m, which is generally the size used when producing aluminum parts. However, in the case of the specialty stainless steel that the company buys, the mill supplies the sheet in a variety of strip sizes—typically 330–550mm wide by 1000–1500mm long—which is placed transversely across the machine’s shuttle table for processing.
“Fashion has a bad habit of making very surface-level changes. It’s not just about adding more black models. People don’t think about the factory workers who are, honestly, almost always people of color. How meaningful would it be to make something beautiful that is also empowering?”—Aurora James, designer
I did something very similar in my Honda Fit. Although since I only used it for two nights, I didn’t go to the same finish with it. I will if I start using it more. I just took out one front seat and made a platform that goes in and out in pieces.
Pratt is also concerned about the wider impact that layoffs could have on the town. This past summer, Briggs & Stratton, a manufacturing company that is the area’s largest employer, cut two hundred employees. Many of Mid-Continent’s workers have been there for more than a decade (Pratt has been with the company for twenty-nine years); should Mid-Continent shut its doors, it would be tough for these workers to find new jobs in town. “That weighs on me every day,” Pratt said. “It would be devastating.”
I really appreciate this post. I’ve been looking all over for this! Thank goodness I found it on Bing. You have made my day! Thank you again!
Fiber laser technology is and will remain an important topic for sheet metal workers. Bystronic fiber laser cutting systems provide outstanding cutting results, not just with thin sheets but also medium sheet thicknesses. This can represent a key competitive advantage as manufacturers who can cut quickly while maintaining high quality standards will be more successful.
I live in California and would love a high speed rail! The citizens of California voted for one in 2008. Unfortunately, it is overbudget and behind schedule, like most infrastructure projects in California. I wish we hired a Chinese or Japanese maglev company to build it rather than have it be slowly administered by the incompetent elected leaders of this state.
All and all, it was a well-organised, well equipped and well planned show, capable of showcasing all the types of tools and machinery to equip oneself to deliver a product of higher quality in a shorter period of time with less human effort.
I like the helpful info you provide in your articles. I’ll bookmark your blog and check again here frequently. I’m quite certain I will learn plenty of new stuff right here! Good luck for the next!
Wire a double pole double throw switch to the cabin fan motor. Add in a PWM based speed controller on your loop. Switch in position A = normal car controls run the fan, position B = override.
I’ve read some excellent stuff here. Definitely value bookmarking for revisiting. I wonder how much attempt you put to create such a excellent informative site.
