Systems and methods for coating surgical needles are provided.

A method for treating surfaces of fasteners made of titanium alloy or corrosion-resistant steel using a sol-gel pretreatment process prior to the application of an aluminum pigment coating. The sol-gel pretreatment process produces an interface film on the fastener surface, which interface film comprises an organometallic-based network system. The interface film aids in improving adhesion and surface roughness when fasteners are used in interference fit conditions (i.e., the hole diameter is smaller than the fastener shank diameter).

A method for performing multiple operations on a lens includes performing a first operation on the lens with the lens secured to a suction device at a first pressure value within the suction device. The method further includes changing pressure within the suction device to a second pressure value different from the first pressure value using a controller and performing a second operation on the lens with the lens secured to the suction device at the second pressure value.

A golf ball includes a core, a cover and a coating layer disposed entirely about an outer surface of the cover. The coating layer is opaque about an entirety of the outer surface of the cover and consists of three regions: a first color region, a second color region, and a transition color region disposed between the first color region and the second color region about an entire circumference of the golf ball. The first color region consists of a spray-painted first color. The second color region consists of a spray-painted second color that is different than the spray-painted first color. The transition color region consists of a combination of the spray-painted first color and the spray-painted second color, wherein said combination produces a transitional color that is a spectrophotometer-measurable different color than both the first and the second colors.

In the coating apparatus for granular bodies is disposed a rotatable hollow cylindrical drum in which there is an introduction apparatus for granular bodies and at least one movable separating element therein, with which a cycle zone can be partly separated from a downstream cycle zone and a movement of the at least one separating element that leads to release is achievable. An interior of the drum is divided into at least one cycle zone and a further cycle zone. A spray apparatus is disposed in one cycle zone, and an outlet in a cycle zone arranged downstream. A separating element is movable from a closed position into an open position. A separating element has a clear space above the closed subregion and an opening between one cycle zone and a cycle zone arranged thereafter, through which granular bodies can pass.

In a method of treating a particulate landscaping material, the material is fed into a mixing chamber and an additive mixture including a functional additive and a carrier is delivered to spray nozzles within the mixing chamber. At least one of the spray nozzles is operated to direct an atomized spray into the mixing chamber. The material is agitated within the mixing chamber during and/or after directing the atomized spray into the mixing chamber. The material is then conveyed with the additive mixture applied thereto to a mixing chamber outlet. During these steps, a volumetric flow rate of the particulate landscape material through the mixing chamber is intermittently determined. The determined volumetric flow rate is intermittently compared to a predetermined target flow rate of the particulate landscape material. Based on this comparison, the volumetric flow rate of the particulate landscape material through the mixing chamber is adjusted.

The present disclosure relates to a coating method of implant using parylene, for coating a surface of a dental implant, including a pretreating step of pretreating the implant; and a coating step of coating a surface of the pretreated implant with a coating material to form a polymer coating layer, wherein the coating material is provided as parylene.

A fastener sealing material for application to miniature and sub-miniature fasteners is formulated from a liquid applied acrylate material. The liquid applied acrylate material is cured using an ultraviolet or LED light source, without the use of heat. When applied to a fastener, the fastener sealing material can form a locking material for the fastener. A method of making a fastener with a sealing material thereon is also disclosed.

The present disclosure is directed to fishing lures with interchangeable scents and methods of embedding scents in fishing lures. In an embodiment, a fishing lure configured to be customized with different scents includes a body, and a plurality of attachments configured to be attached to and detached from the body, wherein a first attachment of the plurality of attachments includes a first scent, and a second attachment of the plurality of attachments includes a second scent, and wherein the first attachment and the second attachment can be interchangeably attached to and detached from the body at a same location of the body.

The present disclosure is directed to methods and apparatuses for embedding a scent in a fishing lure. In a general example embodiment, a device for adding a scent to a fishing lure includes a body including an inner space configured to be isolated from an outside environment and a container for a scented liquid, an attachment mechanism configured to suspend the fishing lure within the inner space of the body, a heating mechanism configured to raise the temperature of the scented liquid to create steam, and a control unit configured to cause at least one of: (i) a pressurization mechanism to increase pressure within the inner space to cause the steam to add a scent to the fishing lure; or (ii) a charge to be applied to the fishing lure to cause the steam to add the scent to the fishing lure.
