  • Patent number: 6550522
    Abstract: A level adjuster for window shades facilitates the level adjustment of the lower rail, in a single operation without requiring any disassembly of the installation. The adjuster comprises a clip or clamp installed in one end of a conventional hollow rail. The adjuster clip has a pair of arms and a tongue or shoe extending into the rail interior, bearing against a crossmember extending between the two arms. The draw cord or lifting line extends as a continuous length through one rail, down each side of the shade assembly, and through the opposite rail where it wraps around the adjuster crossmember and is gripped by the gripping shoe. Lower rail adjustment is accomplished by inserting a tool (nail, etc.) through a hole in the end of the adjuster to flex the resilient shoe away from the crossmember, thereby freeing the lifting line gripped between the shoe and crossmember.

  • Patent number: 4924784
    Abstract: A burner for the firing of pulverized solvent refined coal is constructed and operated such that the solvent refined coal can be fired successfully without any performance limitations and without the coking of the solvent refined coal on the burner components. The burner is provided with a tangential inlet of primary air and pulverized fuel, a vaned diffusion swirler for the mixture of primary air and fuel, a center water-cooled conical diffuser shielding the incoming fuel from the heat radiation from the flame and deflecting the primary air and fuel steam into the secondary air, and a watercooled annulus located between the primary air and secondary air flows.
