Abstract: The present invention relates to the use of a high intensity, in-line rotor-stator apparatus to produce fine particles via antisolvent, reactive, salting out or rapid cooling precipitation and crystallization.

Abstract: A reversible slip clutch, which comprises a first shaft, a first spur gear driven by an external source, a second spur gear rotatably mounted at one end of said first shaft, to be rotated by said first spur gear in a direction opposite to the rotation of the first spur gear, a second shaft, a third spur gear rotatably mounted at one end of said second shaft to be rotated by said first spur gear in a direction opposite to the rotation of the first spur gear, a fourth spur gear rotatably mounted inwardly of said second spur gear at the other end of said first shaft, a fifth, output spur gear rotatably mounted inwardly of said third spur gear at the other end of said second shaft, said output spur gear engaging said fourth spur gear, and means for providing alternate inward pressure to said second and third spur gears to thereby urge said second spur gear to frictionally engage said fourth spur gear and said third spur gear to frictionally engage said fifth spur gear.

Abstract: Fusing apparatus for fixing toner material to a copy sheet. The apparatus comprises a pair of parallel, cold pressure fixing rollers, each of said rollers including a cylindrical metal tube open at both ends thereof, a cured elastomer occupying the volume enclosed by and bonded to said cylindrical tube, and a shaft extending through and bonded to said elastomer. The shaft is concentric with the tube. The apparatus also comprises means for applying a force to one of the two roller shafts to thereby apply a uniform pressure to the nip of the cold pressure fixing rollers.

Abstract: A paper cassette for storing two different lengths of paper sheets. The cassette comprises a rear panel, a pair of side panels extending forward from the rear panel, a front panel operatively connected to the pair of side panels, a bottom panel extending between the bottom of the side panels from the bottom of the rear panel about three quarters of the distance toward the bottom of the front panel, and a top panel extending between the top of the side panels from the top of the rear panel about three quarters of the distance toward the top of the front panel.

Abstract: Apparatus in an electrophotocopying machine having a reciprocating carriage moved by an endless drive member for reversing the direction of the carriage output drive member without reversing the direction of the endless drive member. The apparatus includes a shaft fixedly mounted to the housing for the electrophotocopying machine, the shaft having a flange extending radially outwardly from a central portion thereof, an input drive member rotatably mounted at one end of the shaft and axially slidable along the shaft, the input drive member having apparatus for drivingly engaging the endless drive member, and an output drive member rotatably mounted at the other end of the shaft, the output member having apparatus for frictionally engaging the input drive member and apparatus for driving the reciprocating carriage.

Abstract: A cleaning device for a fixing roller in an electrostatic copying machine, comprising a cleaner support mountable adjacent the fixing roller, a porous oil-impregnated roller rotatably mounted adjacent the cleaner support, a cleaning felt adjustably secured about the cleaner support and the oil-impregnated roller, means for urging the cleaning felt into wiping contact with the fixing roller, and means for incrementally advancing the cleaning felt in wiping contact with the fixing roller can be maintained clean.

Abstract: A highly effective, multi-purpose mechanical snubber is achieved by providing an elongated, centrally disposed, axially movable rack member controllably engaged with at least one worm, having an axis of rotation substantially parallel to the central axis of the rack member and mounted for rotation about said axis in response to axial translation of the rack member. In one embodiment, the mechanical snubber also incorporates an inertial mass which is rotationally responsive to the rotational movement of the worm. By employing one or two worms and rotationally driving the inertial mass in similar or opposed directions, various alternative vibratory control systems are achieved with the single mechanical snubber construction of this invention.
