Case-hardening is a method of giving surface strength to a specific material. Hardening can only take place under conditions where there is a carbon content in the steel. In the case of some wind turbines, the gear wheels are made of a special, low-carbon, chrome-nickel steel. After the teeth are machined, the gear wheels are packed into large boxes full of bone flour or some other form of high carbon-content powder. The boxes are placed in an oven and heated for about 24 hours to a red glowing temperature. During this baking process, some of the free carbon will be transferred from the surrounding carbon-rich powder in the boxes to the gear wheel teeth surfaces.
I was reading an article on BlogTO about the Urban Design Streetscape Manual when I saw an advertisement for Winterlicious 2012. This year, Winterlicious will run from January 27 to February 9. Restaurants have been taking Prix Fixe reservations since January 12, so book your places now!
A couple years ago, I tried to put together a list of restaurants that offer vegan and vegetarian options for Summerlicious. It’s been a while since I revisited the ‘Licious menus and I noticed that the City of Toronto offers more informative restaurant listings.
I went down to the festival after work on the Friday to take a look around and eat some good food. I’m clearing my side table of all the business cards, brochures and pamphlets and I’m making a list of some of the companies and other stuff that were at the Toronto Vegetarian Food Festival this year.
