摘要： A golf ball containing a layer, which comprises nanosheets of exfoliated graphite dispersed in a polymeric matrix, is provided. Exfoliated graphite is graphite that has been intercalated preferably by an oxidation process, where the atoms or molecules have been inserted into the inter-planar spacing between the layered planes of carbons, and expanded. The intercalated graphite is expanded or exfoliated preferably by brief exposure to high heat to expand the thickness of the graphite. The expanded or exfoliated graphite is then mixed with monomers and polymerized in situ to form a polymer with a network of nanosheets of the exfoliated graphite dispersed therein. The exfoliated graphite advantageously retains its nanostructure during the polymerization process. The resulting golf ball layer comprising such polymer with nanosheets of exfoliated graphite exhibits superior tensile strength, low permeability to gas and increased impact strength. A golf ball comprising a water vapor barrier layer, wherein the water vapor barrier layer comprises a foil of compressed exfoliated graphite layer, is also provided. The expanded or exfoliated graphite is compressed together into flexible thin sheets or foils. Such sheets may also be made with a polymeric binder.

摘要： The present invention relates to an method and apparatus for springing sporting racquets to maintain differential tensions between racquet strings within the racquet, so that it is possible to provide racquets having predetermined properties of elastic quality. To maintain differential tensions between the strings, the strings are tensioned against frictional surface, with may be a high frictional surface such as a grommet strip, corner of a racquet string hole, or a pad of high friction material extending about the outer surface of the racquet.

摘要： This invention refers to a novel ballgame racket, especially a tennis racket, including a racket head formed by a tension frame with stringing, and also having a grip portion joining the tension frame, for example by means of a crossing and formed by a gripping shaft or a racket neck and a handle. The racket has a mechanism for tensioning the strings which includes a two part tension frame of the racket head. The frame has a closed hollow profile with a second wing like profile in touch with the closed profile with a damping element placed therebetween.
