Abstract:
A coating apparatus for coating a rollable device including a device rotator having a pair of rollers and spray nozzle is described. The spray nozzle produces a spray of coating material that is directed towards a gap that is between the rollers of the pair. The majority of any spray not deposited on the rollable device during a coating process passes through the gap between the rollers.
Abstract:
The invention provides a stent delivery system and a stent device. The stent delivery system includes a catheter, a balloon operably attached to the catheter, and a stent disposed on the balloon. The stent includes at least one coating applied by dipping a portion of the stent into a coating liquid while simultaneously rotating the stent. The stent device includes a body and at least one coating rotationally applied to a portion of the body, while the body is at least partially immersed in a coating liquid.
Abstract:
The invention provides an apparatus for coating a device comprising a coating chamber and a device rotator having at least one device mount wherein the apparatus allows insertion and retraction of the device on the device mount into and out of the coating chamber. In another aspect, the invention provides a method of applying a substantially uniform coating on a device comprising the steps of providing an apparatus for coating a device, mounting the device onto the device mount, purging the coating chamber to reduce humidity in the coating chamber, maintaining a reduced humidity content in the coating chamber, inserting the device into the coating chamber, disposing a coating material on the device and rotating the device mounts about the device axis.

Abstract:
The invention is an apparatus and method for providing substantially uniform high peak irradiation of a three-dimensional object 12) with at least one curved surface (14). The apparatus includes a source of light (18) for providing light to irradiate the at least one curved surface of the three-dimensional object; a first curved light reflector (22) which reflects and converges light from the source into a first converged light beam (26); a second curved light reflector (24) which reflects and converges the first converged light beam into a second converged light beam (28) with the second light beam being redirected in direction relative to the first light beam toward a target area at which the three-dimensional object is positioned when being irradiated; and at least one light reflector (32, 34, 60) which extends from at least one of the first and second curved light reflectors which reflects and concentrates the second light beam toward the target area at which the three-dimensional object is positioned when being irradiated.
Abstract:
An apparatus and method for simultaneously coating and measuring a part. The apparatus includes a part support, a sprayer and a part measurer positioned adjacent to the part support and a display device positioned adjacent to the part support. The sprayer applies a coating to a section of the part while the part measurer continuously measures a dimension of the section of the part being coated. In one embodiment, an initial amount of coating and a final amount of coating are applied to the section of the part based on the dimension measurements and desired dimension of the part. In another embodiment, the amount of coating applied to the part is based on the desired coating thickness. As a result, the apparatus and method of the present invention significantly reduces the margin of error related to the application of coatings to parts.
Abstract:
The apparatus and method described utilizes a discrete deposition process to apply materials to an optical substrate. The materials can be applied to an optical substrate to create an ophthalmic lens or apply a coating to a lens or other optical surface. Average surface roughness below 10 nanometers can be achieved using the described apparatus and method. Localized error is minimized to less than 1 micron over a 1 mm linear distance to avoid a lens anomaly such as a localized power distortion or power wave. Coating is applied to an entire substrate surface or selected portions. Material can be deposited on the optical substrate to provide the substrate with desired refracting properties. One or more surfaces of the substrate can be coated. Waste material is minimized and a uniform coating is applied for the improvement of optical qualities of the substrate.
Abstract:
A powder coating apparatus 100 and a method of manufacturing a stator 200 are disclosed wherein the stator is set in masking caps 110, 120 such that axial end faces of the stator are masked by the masking caps, respectively, so as to define a first clearance in an area closer to a powder spray nozzle 160 and a second clearance in the other area remote from the powder spray nozzle. The first clearance closer to the powder spray nozzle 160 is set to have airflow resistance less than that of the second clearance remote from the powder spray nozzle for thereby permitting compressed air, delivered from a compressed air supply unit 150, to be discharged through the first clearance at an increased flow rate.
Abstract:
An apparatus and method for simultaneously coating and measuring a part including a part support, a sprayer, a part measurer including a digital camera and a display device, all of which are positioned adjacent to the part support. The sprayer applies a coating to a section of the part while the part measurer continuously measures at least two dimensions of the section. The digital camera takes at least one picture of the entire section of the part while the part is being coated and enables a user to accurately determine the cross section of the part to the optimum finished part configuration and size and also detect defects, blemishes or coating irregularities formed on the section. The apparatus and method of the present invention significantly reduces the margin of error related to the application of coatings to parts, the number of defective parts and increases the overall efficiency.
