  • Publication number: 20240197363
    Abstract: A nasal valve implant delivery system includes a delivery tool having a handle and a needle extending distally therefrom and configured to hold an implant therein. When loaded in the needle, the implant proximally abuts or is disposed adjacent to a pusher member disposed partially within the needle. A light source disposed within the delivery tool is coupled to an optical fiber carried within a lumen of the pusher member. The delivery tool includes a moveable needle shuttle disposed in the handle that is coupled to the needle. An actuator disposed in the handle is configured to releaseably engage with the moveable needle shuttle, wherein the needle shuttle is coupled to one or more springs configured to apply a proximal tensioning force on the needle shuttle, wherein actuation of the actuator retracts the needle proximally into the handle and releases the implant.

  • Publication number: 20230097970
    Abstract: A process for generating a real estate valuation, the process including providing a server integrated with a multiple listing service database, a real estate transaction standard, and an internet data exchange, providing adjustment values for a property by input of a user, selecting a geographical location, preparing and executing a query of properties in the geographical location with similar adjustment values, weighting results of the query according to pre-determined metrics selected by the user, converting results into a linear algebra problem, using a weighted linear regression to determine adjustment values, determining if the adjustment values are reasonable, and generating a graphical user interface displaying the results.

  • Publication number: 20180327632
    Abstract: A wet on wet process for multilayer coating of a substrate includes applying on the substrate to be coated a surfacer layer of an organic solvent-based surfacer coating composition comprising at least one polyaspartic acid ester, at least one polyisocyanate cross-linking agent with free isocyanate groups, at least one pigment and/or extender and at least one organic solvent. The surfacer layer on coated substrate is flashed off and a top coat layer is applied on the surfacer layer.

  • Patent number: 7393556
    Abstract: A process for multilayer repair coating, comprising the following steps: applying a first base coat layer of a conventional, water-borne base coat I containing at least one special effect pigment, applying a second base coat layer of a water-borne base coat II onto the resultant coating, wherein the water-borne base coat II for producing the second base coat layer is feathered out into the zones bordering the repair coating, and wherein this water-borne base coat II comprises A) at least one water-dilutable binder, B) at least one special effect pigment, C) at least one matting agent, D) water and E) optionally, conventional coating additives and/or organic solvents, with the proviso that the water-borne base coat II contains the at least one special effect pigment in a quantity of 25-75 wt.

  • Publication number: 20080014368
    Abstract: The invention is directed to a method for refinishing vehicles using infrared technology for drying and curing the paint coating. The method comprises the steps: A) applying a layer of a pigmented coating composition over a vehicle body or vehicle body part, subsequently applying a layer of clear coating composition, or applying alternatively a layer of pigmented top coating composition over the vehicle body or vehicle body part and B) curing the coating layers applied in step A), directly after completion of the application step, without interposing a final evaporation phase, by exposing to infrared radiation using a short-wave infrared radiator, a radiator distance in the range of 20 to 60 cm being adjusted and the quotient of radiator power in Kilowatt and radiator distance in centimeter ranges from 0.07 to 0.15.

  • Publication number: 20050238802
    Abstract: The invention relates to a process for multi-layer special effect coating of substrates comprising the following steps: A) applying a colour-imparting solid-colour base coat layer of a conventional colour-imparting solid-colour base coat I containing conventional colour-imparting absorption pigments onto a substrate precoated with a filler and/or primer coating composition and optionally, further coating compositions, B) applying a special effect base coat layer of a metallic base coat II, which contains aluminum pigments in flake form with an average particle thickness of 0.01 to 0.10 ?m and an average particle size of 5-50 ?m, onto the base coat layer applied in step A) in a film thickness which is reduced relative to the film thickness produced in step A), C) optionally intermediately drying the coating so applied, D) applying a clear coat layer of a transparent clear coat and E) curing the thus obtained coating.

  • Patent number: 6777033
    Abstract: The present invention relates to a spot repair finish process for refinishing substrates, in particular vehicle bodies or parts thereof, wherein a very good quality finish is produced with virtually no differences, such as in color shade or overspray margins and edge marks, visually perceptible between the old finish and the repair finish. The spot repair process of the present invention works especially well with pigmented coatings of critical color shade, in particular with specific light color shades.
