Abstract: The invention relates to a sealable, molded body and the production thereof, as well as a composite film for the formation of the molded body, and the use of the molded body for the packaging of oral biologics, in particular orally applicable vaccines. The composite film comprises two outer layers, one of the outer layers is formed as a sealing layer, or a barrier layer or a carrier layer, and the other outer layer has a rough or uneven or microstructured surface or comprises at least a nonwoven material, an adhesive material, a sticky material or a combination thereof. It is preferred that the composite film is biologically degradable. A molded body, which takes up the biologic or the vaccine, is formed from the composite film by thermoforming, and is then sealed.

Abstract: A racket for ball games may include a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations that are symmetrical relative to the longitudinal axis of the racket may be provided in the heart region of the frame. A vibrating device may be arranged in each of the two indentations. The vibrating means of the racket may preferably be effective for vibrations having at least two vibration modes or degrees of freedom. Additionally or alternatively, a racket for ball games may include a frame which forms a head region for receiving strings and a handle portion for holding the racket. The frame may include one respective inwardly-facing C-profile in at least two segments of the head region.

Abstract: The racket (2) for ball games of the present invention comprises a frame which is formed by a frame profile or a hollow profile and has a racket head and a handle portion connected thereto preferably via a heart region. Two indentations (12) that are symmetrical relative to the longitudinal axis of the racket are provided in the heart region of the frame. A vibrating device (20) is arranged in each of the two indentations. The vibrating means of the racket of the present invention are preferably effective for vibrations having at least two vibration modes or degrees of freedom. The invention further relates to a racket for ball games comprising a frame which forms a head region for receiving strings and a handle portion for holding the racket, wherein the frame comprises one respective inwardly-facing C-profile in at least two segments of the head region.

Abstract: The present invention relates to a dampening device for ball game rackets. The dampening device of the present invention includes at least one dampening element having a foot or base region, a head region and a neck or connection region arranged between the foot region and the head region. The provision of a neck or connection region leads to an optimum distance between foot or base region and head region and/or an optimum and safe positioning of the head region in the stringing plane at a preferred distance from the heart region of the racket. Preferably, the neck region is tapered or necked relative to the foot or base region and/or the head region at least in the width or thickness direction of the dampening device of the invention.

Abstract: The present invention relates to a dampening device for a ball game racket, in particular a tennis, squash, racket ball or badminton racket, as well as to a ball game racket comprising a dampening device of this kind. The dampening device according to the invention comprises a base body made of foam material and a connecting means which is configured such that the dampening device can be fixed to at least one longitudinal string, preferably at least two longitudinal strings of a ball game racket without substantially coupling the embraced strings with each other.

Abstract: The present invention relates to a racket, in particular a tennis racket or squash racket exhibiting a particularly suitable stiffness and/or strength behavior. For this purpose, the ball game racket of the present invention comprises a racket head, a heart region and a handle portion which together form the frame, wherein in the area of the racket head individual regions are formed which comprise brackets being arranged along the frame in the head region of the racket.

Abstract: The invention relates to a cutter knife adapted to be mounted on a rotatably drivable knife shaft of a meat cutter machine. The blade of the knife is provided with at least one convexly configured margin with a cutting edge therein and a plurality of openings disposed in predetermined relationship relative to the cutting edge, the openings being in longitudinal section of substantially concave configuration and reduce the mass and surface area of the blade from about 15% to about 30% and from about 20% to 50%, respectively, thereby reducing heat accumulation and retention in the blade.
