Golf balls having covers with decorative-effect coatings are provided. The golf balls are fashionable and decorative with unique appearances. In one embodiment, a golf ball comprising a core having at least one layer and cover having at least one layer is provided. The outer cover surface can have surface textured dimples and a decorative-effect first coating can be applied to this outer surface. A transparent second coating can be applied over the decorative-effect coating. In another embodiment, a semi-transparent metallic first coating overlies the outer cover surface and a decorative-effect second coating overlies the metallic coating.

A golf ball comprising a subassembly such as a cover and a coating layer disposed entirely about an outer surface of the subassembly; wherein the coating layer has a first color region, a second color region, and a transition color region that is transitionally disposed between the first color region and the second color region. The first color region has a first color appearance; the second color region has a second color appearance that is different than the first color appearance; and the transition color region has a transitional color appearance that is comprised of the first color appearance and the second color appearance. The transitional color region may be disposed circumferentially about the outer surface of the cover.

Coloring systems and methods include a conveyor that transports a material. An auger is configured to move a colorant from a reservoir to the conveyor. A grinder receives the material and the colorant from the conveyor and grinds the material and the colorant together to produce a colored material.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a vacuum port in an upper portion of the chamber, a chemical delivery system configured to inject a reactant or precursor gas into a lower portion of the chamber, a paddle assembly, and a motor to rotate a drive shaft of the paddle assembly. The lower portion of the chamber forms a half-cylinder. The paddle assembly includes a rotatable drive shaft extending through the chamber along the axial axis of the half cylinder, and a plurality of paddles extending radially from the drive shaft such that rotation of the drive shaft by the motor orbits the plurality of paddles about the drive shaft.

Systems and methods for coating surgical needles are provided.

A method and apparatus for forming a sealant coating on a fastener are provided. The apparatus comprises a light generator, a light housing, and a forming cup. The light generator is configured to generate light having a number of characteristics that cures the sealant coating on the fastener. The light housing surrounds the light generator. The forming cup is removably connected to the light housing. The forming cup has an internal cavity with an inner mold line complementary to an outer mold line for the sealant coating.

The invention relates to a coating arrangement for coating particles, a method for coating particles, and corresponding uses. The coating arrangement includes a coating chamber and a coating device arranged in the coating chamber. This device comprises a hollow body with an axis, the inner wall of which forms a particle track around the axis of the hollow body, a particle source and a particle sink, and at least one coating source. The coating source is adapted for emitting a coating material along a direction perpendicular to the axis of the hollow body. Furthermore, the coating device comprises a rotation device which is adapted for rotating the hollow body about its axis, and a cleaning device which is arranged in the interior of the hollow body in a stationary manner with respect to the hollow body and is adapted for removing adhering coating material from the inner wall of the hollow body.

A device for adding a scent to a fishing lure, the device including: at least one electrode; and (i) a conductive element configured to place the fishing lure in conductive communication with the at least one electrode; and a control unit configured to activate the at least one electrode to cause the at least one electrode to impart a charge on the fishing lure via the conductive element, or (ii) a source of scented liquid; a heating mechanism; and a control unit configured to (a) activate the at least one electrode to cause the at least one electrode to impart a charge on the fishing lure, and (b) create steam from the scented liquid, wherein ions from the steam are attracted to the fishing lure when the charge is imparted on the fishing lure by the at least one electrode.

A method of preparing a pharmaceutical composition having a drug-containing core enclosed by one or more metal oxide materials is provided. The method includes the sequential steps of (a) loading the particles comprising the drug into a reactor, (b) applying a vaporous or gaseous metal precursor to the particles in the reactor, (c) performing one or more pump-purge cycles of the reactor using inert gas, (d) applying a vaporous or gaseous oxidant to the particles in the reactor, and (e) performing one or more pump-purge cycles of the reactor using inert gas. The temperature of the particles does not exceed 35° C. This produces a pharmaceutical composition comprising a drug containing core enclosed by one or more metal oxide materials.
