    摘要: An impeller for use in association with an extraction plate adapted for defibering liquid slurry stock and causing defibered material to pass through the extraction plate. The impeller includes a cylindrical central body portion and a plurality of vanes extending outwardly in a generally tangential direction from the central body portion. The vane leading face height from an extraction side to an air foil surface is substantially constant from the vane outer end to where the vane is attached to the central body portion at the radially outward edge of the central body portion, and then thereafter gradually decreasing in height from the radially outward edge of the body central portion to the airfoil surface at the vane inner end.

    摘要: A ceiling fan (10) is provided having a motor (12), a motor housing (13), fan blades (14), and blade irons (16) coupled to the motor and blades. Each blade iron includes a mounting arm (18), a mounting plate (19) and a decorative medallion (20). The mounting arm has a blade attachment portion (23) which has a decorative end (24) with mounting holes (25) therein. The blade iron mounting plate has a middle portion (31) straddled by a first end portion (32) and a second end portion (33). The middle portion and blade each have mounting holes (34) and (36), respectively, therein configured to conform with the mounting holes of the decorative end. The decorative medallion includes a cover plate (37) having a cavity (38) therein partially defined by an interior end wall (40) configured to mate with the first end portion (32) of the mounting plate. The medallion also includes two springs (43) configured to bias the cover plate away from the mounting plate and a set screw (45) mounted within a set screw mounting hole (46). The set screw is threadably movable between an unlocked position separated from the second end portion of the mounting plate and a locked position contacting and biasing against the second end portion.
