Title: Method for the production of a artery prosthesis
Inventor: BRAUN BERND DR DIPL CHEM
IPC: F16L11/10
Filed: 1984-11-24
Granted: 1989-07-20
Abstract: To produce a vessel prosthesis, a hose (12) is wrapped with a reinforcing thread (13) to avoid bending and clogging of the vessel prosthesis. The reinforcing thread (13) is wound substantially tensionless on the soft hose (12) thus prohibiting wavy deformations inside the hose. To exclude prior to the solidification of the adhesive connection a displacement of the reinforcing thread (13) being bonded to the hose, a band-shaped spacer (14) is wound up together with the reinforcing thread (13) and removed subsequently.

Abstract: A wrap-around bottle carrier wherein the bottle heel cutouts at the ends of the carrier are spaced from the ends a greater distance than normal to increase the strength of the carrier at this area of stress. To permit this arrangement to be used, the shape of the outer or end cutouts is altered by connecting the top of the cutout to the vertical inner side portion of the cutout by a straight cut rather than by the usual curved cut. This allows the edges of the end cutouts to contact the bottles when the carrier is lifted even though, due to the change in dimensions of the end cutouts, the end cutouts are not symmetrically arranged with respect to the centerline of their associated bottles.
