Abstract: A method for the manufacture of a metallic protective device such as a metal leading edge for a component such as a gas turbine engine composite fan blade, an aluminum alloy fan blade, or other component requiring a metallic protective device. The method can be used to manufacture a near net shape metallic leading edge using a powder bed fusion process. Powder bed fusion technology utilizes a digital three dimensional computer aided design model of a component to manufacture the part with a layer by layer material build-up approach.

Abstract: A restricted contamination environment device allows the production (compounding) of sterile drugs products or other products that may need processing in a sterile (restricted contamination—either viable or non-viable) environment. The device can be used to prepare a “single dose” (making one dose, or single application only), prepare multiple single doses, and prepare multiple dose dispensers or to prepare multiples of multiple dose dispensers. In one example, a collapsible container is packaged with the vials, containers, syringes, parts and/or accessories within the container. The container may be folded or collapsed to minimize space prior to use. The container may then be “inflated” by some means either external or internal that would maintain the “contamination” free environment.

Abstract: A device (10) for non-gravity presentation of a droplet (16) of a liquid (12). The device includes an applicator (20) for forming the droplet and a squeeze-type bottle (18) that contains the liquid used to form the droplet. The applicator includes an upwardly-facing presentation surface (36) upon which the droplet is formed. One or more capillary tubes (38) communicate liquid from inside the bottle to the presentation surface via an uptake tube (40) when a user squeezes the bottle. Each capillary tube has a diameter of no greater than about 0.0787 inch (2 mm). Once the droplet has been formed, the user may tilt the device up to a critical tilt angle ?critical, above which the droplet will fall from the presentation surface. When the device is tilted to a tilt angle ? less than or equal to the critical tilt angle, capillary attraction between the droplet and the capillary tube(s) retains the droplet on the presentation surface.
