Fluidized bed reactor - Wikipedia

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

How to Glass Bed Your Rifle | Boyds Hardwood Gunstocks

How To Glass Bed Your Rifle - by Randy Boyd. When you fire your rifle, an upward motion of the barrel is created which causes a pulling action on the stock. Dependent on the caliber, this can be quite violent. If your action isn't bedded firmly into the stock, this movement can create the opportunity for your barrel and stock to collide .
