Abstract: A method for masking cooling passages of a turbine component having an external surface, an internal cavity for receiving cooling air, and cooling passages extending therebetween. The location and angle of cooling passages are determined using a robotic arm and a location system. A masking device is placed in the cooling passages located during the locating step. The masking device includes a head portion having a gripping feature for gripping by a robotic arm, and a locating feature for orientation of the masking device by the robotic arm. A retaining portion extending from the head portion is arranged and disposed to retain the masking device in a cooling passage. The retaining portion is narrower proximate a distal end than proximate the head portion. The component and head portion of the masking devices are coated. The masking devices may be removed using the robotic arm and locating system.

Abstract: Systems and devices for the isolation of biological agents that are infused in a solution causing those agents to float. These systems and devices have numerous research, diagnostic, clinical, consumer, and other applications. An aspect of the disclosure provides for an apparatus for isolation or enrichment of biological agents from a sample comprising: a sample container comprising an inner volume to hold a sample and a plurality of micro bubbles, a tapered end and an open end, a plunger inserted into the open end and a tip of the tapered end forming an acute angle relative to the horizontal axis of the sample container, wherein the plurality of micro bubbles float one or more biological agents of the sample and wherein the plunger moves towards the tip to isolate or enrich the one or more biological agents from the sample.

Abstract: A sprayer that includes a tank for containing a liquid pesticide, herbicide, or the like, a pump for pressurizing the liquid contained within the tank, and a hose and wand assembly for dispersing the pressurized liquid onto an area of interest, such as weeds. The tank includes an opening formed through its top surface through which liquid can be poured into tank. A wide mouthed funnel defines the opening to assist in preventing fluid from spilling while being poured. The bottom of the tank is attached to a base unit that provides a reservoir for any liquids dripping on the exterior of the tank, while also providing a flared region in which the end of the wand can be positioned when not in use. A wand retaining clip is attached to the exterior of the funnel to secure the wand while not in use and further to direct the end of the wand into the flared region formed in the base of the unit.

Abstract: A gun safe for storing guns in a generally upright position is provided. The gun safe comprises an interior compartment which is defined by a top wall, one or more side walls, and a bottom wall. The top wall has at least one opening through the top wall to provide support for a barrel of a gun positioned within the gun safe, with the barrel extending through the opening to the exterior of the gun safe.
