I don't know if you have a different term for them in Sweden, but they are how we washed clothes a century ago, before automated washing machines. It's a rough metal plate in a wooden frame that sticks out of a bucket of soapy water, and you rub the clothes on it to flush out the dirt. If the wash board is patented, and someone still owns that patent, it's very unlikely that anyone in the business world would consider that patent to be worth anything, for the obvious reason. I think the washboard would've gone the way of the Audion...the patent expired if it WAS patented. -Dave -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
