The present invention relates to a medical device for placement at a predetermined location within a passageway of the human body, and more particularly, relates to a flexible expandable embolization device which may be delivered by a catheter to a pre-selected position within a blood vessel to thereby embolize a blood vessel or a blood vessel defect, such as an aneurysm or fistula.

A fan variable area nozzle (FVAN) includes a flap assembly which varies a fan nozzle exit area. The flap assembly generally includes a multiple of flaps, flap linkages and an actuator system. The actuator system radially and axially translates a drive ring relative an engine centerline axis. A slot within the drive ring receives the flap linkages to asymmetrically and symmetrically vary the fan nozzle exit area in response to movement of the drive ring.

The invention provides an improved method of forming one or more box blanks (20) from a generally-rectangular sheet of material, comprising the steps of: providing a frame (28) for supporting and guiding the sheet; placing a sheet of material on the frame; controllably moving the sheet in a longitudinal direction relative to the frame; providing at least one longitudinal score line (21) on the sheet as the sheet moves relative to the frame; punching a first hole in the sheet; cutting a first slot (23) in the sheet between one longitudinal edge thereof and the first hole; punching a second hole in the sheet at a position spaced transversely across from the first hole; cutting a second slot (23) in the sheet between the other longitudinal edge thereof and the second hole; providing a transverse score line (22) on the sheet between the first and second holes; punching longitudinal slots in the sheet to severe the flaps (24) from the glue tab (27); and cutting the sheet to the length required for the desired shape and dimensions of the box; thereby to provide a creased and slotted box blank.

A machine to fold a cardboard blank into an open tray, the machine including means to displace a blank from a stack of blanks to a table, means to clamp the blank in a fixed position to the table, folding means to fold up sides and ends of the blank into vertically extending walls, consolidation means to urge overlapping flaps of the sides or ends into slots in the base of the blank and, means to eject the open tray from the machine.

The invention provides an apparatus (26) for forming a box blank from a generally-rectangular sheet of material. The apparatus has a frame (28) for supporting and guiding the sheet; and endless advancement belt (31) for controllably moving the sheet relative to the frame through the apparatus; guide rails (32) extending generally across the sheet; a carriage (34) mounted on the guide rails for horizontal movement relative thereto; a cutting blade (35) mounted for horizontal movement with the carriage and operatively arranged to be rotated about an axis; a blade actuator (36) for selectively causing the blade to have a vertical component of movement relative to the carriage; a punch (38) mounted on the carriage and selectively operable to punch a hole in the sheet; a transverse creasing roller (39) mounted on the carriage; and a pair of adjustable longitudinal creasing rollers (40) mounted on the platform. As the sheet is moved relative to the frame, the transverse creasing roller may selectively crease the sheet in a transverse direction, the longitudinal creasing rollers may selectively crease the sheet in a longitudinal direction, and the cutting blade may selectively cut slots from both longitudinal edges.

Method and apparatus for forming slotted and creased box blanks

Apparatus for processing a sheet of material such as cardboard intended for making a folding box or case, comprises a stamping plate for carrying the sheet and co-operable with a tool. The stamping plate lies on a table plate of a frame structure which has holders for releasably carrying a form which extends parallel to the table plate, and at least one bridge assembly which extends movably above the table plate. A carriage is carried on the bridge assembly and moves transversely with respect to the direction of travel thereof. The carriage carries at least one vertically movable pressure member directed towards the table plate.
