摘要:
Disclosed herein is a game ball and method for making the same. The game ball has an ionomeric cover which includes a combination of ionomeric crosslinks and covalent crosslinks. The game ball cover is superior in at least one of cut resistance and scuff resistance to a conventional cover that does not have covalent crosslinks but is otherwise substantially identical in composition. Crosslinks within the composition are achieved by irradiation. The game ball cover of the invention is particularly useful for improving the durability of golf balls to be struck with sharp-grooved clubs.
摘要:
A method for improving the adhesive bonding of a top coat to a game ball such as a golf ball while simultaneously forming an identification stamp on the ball by (i) stamping an unfinished golf ball with a radiation curable ink and (ii) subjecting the unfinished golf ball to irradiation prior to application of a finish or top coat. Game balls so treated exhibit superior adhesion of a top coat and avoid the need for application of a primer coat between the unfinished golf ball and the outer top coat.

An improved American football comprising an inflatable, one piece bladder formed in a generally elliptical shape and fabricated of an elastomeric material; four panels secured together over the bladder, each panel being of a similar, generally oval shape with inturned edges secured together by stitching to form four seams; an essentially inextensible liner formed of four liner components, each liner component being of a similar, generally oval shape with inturned edges secured together and to an associated panel by stitching to form four seams, the liner components being located between the panels and the bladder, an opening formed centrally along a part of one seam at a location where the panels and liner components are not stitched; lacing located along the opening to couple the inturned edges in place of the stitching; closure means comprising two patches and a tongue located between the bladder and liner components, the patches being stitched to the liner components, the patches being stitched to the liner components and panels on opposite sides of the opening, the tongue being stitched to a liner component and panels and extending to a location between the bladder and patches; and a counter weight of a high density elastomeric material, and of a weight substantially equal to that of the lacing and closure means and molded to the bladder externally thereof along the seam of the panels opposite the lacing.

The present application provides methods of treating and preventing infections in the lung, such as Pseudomonas infections, comprising administering substantially non-anticoagulant 2-0, 2-0 desulfated heparin (ODSH) to subjects suffering from, or at risk for, chronic or acute pulmonary infections. ODSH can be administered alone or in combination with one or more other therapeutic agents, such as anti-microbial or antibiotic agents, mucolytic agents, DNases, bronchodilators, and anti-inflammatory agents. Also, provided herein are pharmaceutical compositions and unit dosage forms of ODSH, optionally in combination with other therapeutic agents, for use in the disclosed methods.
摘要:
Dithiocarbamate, particularly tetraethylthiuram disulfide, and thiocarbamate anions thereof, strongly inhibit the growth of cancer cells of a variety of cell types. Such inhibitory effect is enhanced by heavy metal ions such as copper ions, cytokines and ceruloplasmin. A method is presented for using tetraethylthiuram disulfide to reduce tumor growth, and to potentiate the effect of other anticancer agents.
摘要:
A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product comprising a thermoplastic polyurethane cover further comprising an isocyante or hydroxyl terminated polybutadiene in an isocyanate solution. The precursor product is then removed and heated to remove solvent. The precursor product may then be subjected to gamma or electron beam irradiation.
摘要:
An elastomeric composition for forming a golf ball or a component thereof is disclosed that includes the use of a non-conjugated diene monomer having two or more vinyl (CH2═CH—) terminal end groups. The composition produces a molded product exhibiting an enhanced combination of increased compression (i.e., softness) and resilience (C.O.R.).

Methods for treating cancer are provided including administering a patient needing treatment a therapeutically effective amount of one or more antioxidants selected from the group of catalase, N-acetylcysteine, glutathione peroxidase, salen-transition metal complexes, dicumarol, and derivatives thereof.
摘要:
A game ball having a cover formed from a crosslinkable thermoplastic polyurethane is disclosed. By selective exposure to radiation, the thermoplastic polyurethane cover is crosslinked and its hardness is increased. Typically, increases in hardness values of at least 2 units on the Shore D scale are realized upon exposure to 3.5 Mrads of gamma radiation.
摘要:
A golf ball component, such as a golf ball cover layer, formed from a high or increased melt index thermoplastic polyurethane, polyurea or polyurethane/polyurea is disclosed. The cover layer may be relatively thin (i.e., 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). In addition, an operation in which the outer cover is exposed to an isocyanate solution is described to improve certain physical properties of the resulting golf ball.
