Filed:

Mar 7, 2006

Appl. No.:

11/370126

Inventors:

Jeffrey Chinn - Foster City CA, US
Peter Yang - Palo Alto CA, US

International Classification:

A63B 37/00
A63B 37/14

US Classification:

473351000, 473378000

Abstract:

Improved golf ball exterior coatings which are used to create an extremely uniform hydrophobic or hydrophilic exterior surface on the golf ball. When the surface of the golf ball is hydrophobic, it tends to repel water, and this reduces drag on the golf ball surface as the golf ball travels through the air. When the surface of the golf ball is hydrophilic, the surface of the golf ball wets uniformly and the ball rolls straighter on a wet green, as the forces acting on the ball are more uniform. The hydrophobic or hydrophilic exterior coating is applied to the golf ball using vapor-phase deposition in instances where strict control over coating thickness uniformity, and/or reduced surface roughness is desired.

Abstract:

The present invention relates to compositions and methods of the preparation of an oral particle essentially consisting of an amorphous structure and a submicron domain, wherein both amorphous structure and submicron domain comprise a drug, and wherein the particle shows crystalline property. The desired ratio of the amorphous structure to the submicron domain is between 0.1:5 and 1:1. And, the desired average particle diameter is between mesh 12 (1680 microns) and mesh 100 (149 microns).

International Classification:

A61K 9/20

US Classification:

424474, 51421002, 424464

Abstract:

The present invention relates to a tablet composition comprising a particle and a pharmaceutically acceptable carrier, wherein the particle comprises an amorphous structure and a submicron domain, and wherein the amorphous structure is a molecular solid dispersion of a drug in a polymeric matrix and the submicron domain is a submicron drug particle. The tablet may further comprise a micronized drug particle. The pharmaceutically acceptable carrier comprises a binder, a filler, a lubricant, and optionally a gelling agent, a glidant and an anti-sticking agent.
