Title: Mail encoding and processing system
Inventor: ALLUM DAVID ROBERT
IPC: G06Q10/08
Filed: 1993-05-18
Granted: 2000-01-25
Abstract: Mail can be sorted automatically to point of delivery level by deriving from the address including postal code on a piece of mail a suffix which together with the postal code forms routing data which uniquely identifies the final delivery address.      This is achieved automatically at the Post office sorting facility by means of an optical character reader which reads the addresses on mail items and a computer arranged to generate a suffix based on the address read. The routing data is printed as a bar code on the mail item and this allows the complete sortation to be effected automatically. Also contemplated is a progressive encoding system which can be applied as bar codes by customers as desired to mail pieces. The basic data is the routing data set to which can be added a shipment number which allows automatic revenue accounting control and a piece number which allows automatic track and trace. Finally, the customer may also progressively encode return mail envelopes with the shipment number followed by a product code and a user defined field which permits automatic specialized handling of the return mail item.

Abstract: A system and closure (22) for determining the position of a blood vessel (26) via a percutaneous puncture (24) and for sealing the percutaneous puncture in the blood vessel. The system includes an introduces sheath (28, 28') and associated positioning de-vice.(200, 300, 400, 600), a hemostatic puncture closure (22), and a deployment instru-ment (20). The positioning device (200, 300, 400, 600) enables the introduces sheath (28) to be positioned at a desired position within the vessel (26). The deployment instrument (20) includes a tubular carrier (100) storing the closure (22). The carrier (100) has a dis-tally located free end (104) to be extended via an introducer (28, 28') through the punc-lure (24) and its associated tract (24A). The closure (22) comprises a radiopaque rigid anchor (32, 32'), a compressed collagen plug (30), and a thin filament (34) connecting the two in a pulley-like arrangement. The carrier (100) ejects the anchor (32, 32') through the introducer (28, 28') and puncture (24) and then draws it against the free end of the introducer. The instrument (20) and introducer (28, 28') are then withdrawn to-gether to pull the anchor against the tissue contiguous with the puncture inside the ar-tery. Further withdrawal draws the plug (30) out of the carrier (100) into the puncture tract (24A), whereupon the plug (30) moves with respect to the anchor (32, 32') into en-gagement with the outside of artery wall to seal the puncture or incision (24). A tension-ing device (116, 118, 120, 122) limits the force applied to the filament (34).  The carrier (100) also includes a tamper (130) which is used to mechanically deform the plug (30) within the tract (24A). Once positioned hemostasis occurs rapidly, thereby locking the closure (22) in place.
