Abstract: Apparatus and methods are provided for making coated liners and/or tubular devices including such coated liners. A sleeve may be provided that includes an outer first surface and an inner second surface extending between first and second ends thereof, and a hydrophilic or other coating may be applied to the first. The coated sleeve may be cut between the first and second ends to create opposing edges extending between the first and second ends, and the cut sleeve may be reversed such that the coated first surface defines an inner surface and the opposing edges are disposed adjacent one another, thereby providing a coated liner. Optionally, a tubular structure, e.g., one or more reinforcing layers and/or or outer layers may be attached around the coated liner, thereby providing a tubular device including an inner surface with a desired coating.

Abstract: A correctional paint wand used to mark lines on pavement, turf, concrete, and other surfaces. It has a rotatable sleeve on the lower end of an elongated handle, with the sleeve having at least two aerosol paint can holders each sized for containing one inverted paint can. At least one can applies distinguishable marking paint, and at least one can applies correctional paint visually covering erroneously applied markings, with the sleeve rotated to place the needed paint can in a dispensing position. A wheel on the lower end of the wand may aid its movement over the surface targeted for marking. The error correcting paint may be green for grass or artificial turf, brown for exposed ground, light gray or off-white for cement, and black for asphalt, or other colors appropriate to the intended application. Contemplated applications include, but are not limited to, use by landscaping designers and utility companies.

Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS) that can be modified as desired. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of objects, referred to herein as Object A (Solid A or Liquid A). Use of an external stimuli or degradation of the Liquid B can be utilized to change the characteristics of SLIPS structures reversibly or irreversibly that may be desired in a number of different applications. Numerous characteristics, such as adhesion, optical, mechanical, and the like, can be dynamically changed.

Abstract: Methods for the deposition of silver-comprising films on nonconducting substrates, and, more particularly, to deposition of such films that are very thin, are provided. The surface of nonconducting substrates is modified with a superabsorbent polymer to increase silver deposition when compared to a non-modified surface. Also provided are films produced using a swelling agent, whereby porosity of the surface of the nonconducting substrate is increased, thereby permitting increased silver deposition when compared to an unmodified surface.

Abstract: A method for filling cooling holes in a component of a gas turbine engine is disclosed. The component may include a plurality of first cooling holes penetrating the wall of the component. The method may comprise the steps of exposing the outer surface of the component, filling the plurality of first cooling holes of the component with a filling agent, curing the filling agent to block the passage of air through the cooling holes, and applying a thermal barrier coating over the surface of the component. The method may further include installing a second plurality of cooling holes, the second plurality of cooling holes penetrating the thermal barrier coating and the wall of the component and allow air to pass therethrough.

Abstract: The present invention provides a latent fingerprint detection method that is easy to handle and is capable of clearly detecting a latent fingerprint and a heating evaporation device for detecting a latent fingerprint and a latent fingerprint detection apparatus which are capable of detecting a clear latent fingerprint by a one-time operation by heating a chemical agent at high temperatures in a short time, as well as a composition for detecting a latent fingerprint. This latent fingerprint detection method includes a heating step of heating a chemical agent to be gasified by heating so as to attach to a latent fingerprint on a specimen, and an exposure step of exposing the specimen having the latent fingerprint attached thereto to the atmosphere of the gasified chemical agent. The chemical agent is a mixture of a 2-cyanoacrylic acid ester polymer and a dye.
