An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.

A golf ball component, such as a golf ball cover layer, formed from a reaction injection molded polyurethane, polyurea or polyurethane/polyurea is disclosed. The cover layer may be relatively thin (for example, 0.075 or less, preferably 0.050 inches or less, more preferably less than 0.040 inches, even more preferably less than 0.030 inches). The golf ball component is produced from a fast reacting aromatic polyurethane composition that is PTMEG based.

A ball bat comprising a bat frame in a generally cylindrical configuration. The bat has an essentially cylindrical hitting area and a handle area remote from the hitting area and with a tapering transition zone therebetween. The bat frame is fabricated of a composite material of fibers in a matrix binder. A cylindrical recess is formed in the hitting area and has an annular inner face and parallel end faces at the ends of the recess. An annular insert metal with an interior cylindrical surface is in contact with the inner face of the recess and with parallel end faces in contact with the end faces of the recess and a cylindrical exterior surface essentially flush with the portions of the bat frame on opposite sides of the recess.

A canvas holding assembly for holding large and small canvases includes a base that is tripoidal. A first plate is coupled to and extends from the base. The first plate is substantially parallel to a surface upon which the base is positioned and is configured to position items of a user. A first bar is selectively extendable from a top of the base. A second bar is coupled to and extends from the first bar distal from the base. A first coupler is pivotally coupled to the second bar distal from the first bar. The first coupler is positioned above the first plate. Each of a plurality of holders is configured to couple to a canvas. Each holder comprises a second coupler that is complementary to, and positioned to couple to, the first coupler, such that the holder is configured to couple to the canvas.

The present invention is directed to a multilayer film having an active oxygen barrier layer that comprises an oxygen scavenging composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C) having oxygen barrier properties that can be further enhanced by exposing the composition to a source of ionizing radiation e.g., electron beam radiation. Irradiation improves the oxygen scavenging abilities of the oxygen scavenging composition so that oxygen can be intercepted and scavenged as it passes through the film. The resulting irradiated multilayer film has improved active barrier properties in comparison to the same film prior to irradiation. As result, the multilayer film of the present invention can be used in packaging applications to help maintain a low oxygen atmosphere in the interior of a package.
摘要:
The present invention provides a multilayer film having an active oxygen barrier multilayer core comprising at least one of 1) an active oxygen barrier layer is sandwiched between two passive oxygen barrier layers, or 2) a passive oxygen barrier layer is sandwiched between two active oxygen barrier layers. In one embodiment, the active barrier layer comprises a composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C). In some embodiments the active barrier layer may also include a compatibilizer (D). The passive oxygen barrier layers help to maintain the oxygen barrier properties of the multilayer film after the oxygen absorbing capacity of the active barrier layer has been exhausted. As a result, the useful shelf life of the film can be extended.

Described herein are compositions useful in anticancer treatment and prevention. The compositions are composed of (a) a dithiocarbamate metal chelate and (b) an amphiphile, wherein the amount of amphiphile is sufficient to produce a liposome or micelle. Methods for using the compositions in anticancer treatment and prevention are also described herein.
