Abstract: To provide a general-purpose saw blade which will saw different materials cost effectively, the saw blade includes a plurality of sets of teeth, each set including saw tooth having a large relief angle and a small tooth angle which provide fast cutting speeds, and with saw tooth having a small relief angle and a large tooth angle which provide the resistance to chipping.

Abstract: A new blade, and a method of cutting therewith, having repeating sets of teeth, each set having sub-sets which differ from each other in at least one cutting characteristic including straight teeth, primary cutting teeth which are left-sided and right-sided and secondary cutting teeth which are left-sided and right-sided, said secondary cutting teeth having a large relief angle.

Abstract: Apparatus for separating a continuous stream of filled beverage bottles moving in a single row in one linear direction into a plurality of spaced apart rows of filled beverage bottles moving in a direction substantially perpendicular to such one linear direction using at least first, second and third continuously moving conveyors moving in spaced apart parallel linear directions and a continuously moving collection conveyor moving in a linear direction substantially perpendicular thereto wherein the middle filled beverage bottle of three successive filled beverage bottles is moved at spaced apart intervals over the second or third continuously moving conveyors and onto the continuously moving collection conveyor to form spaced streams of filled beverage bottles thereon and wherein the filled beverage bottles remaining on the third continuously moving conveyor are transferred to the continuously moving collection conveyor to form another stream of filled beverage bottles thereon.
