A first edible layer is placed atop a tray and inside a first annular member, leaving an annular gap around the edible layer. A spreadable material is spread atop and laterally on the first edible layer. A second annular member is stacked upon the first annular member with a second edible layer centered in the second member but with an annular gap between the two. Spreadable material atop and laterally to the second edible layer. The annular members each have an overall transverse dimension greater than its height. These members are part of a reusable kit with the first member has an outwardly projecting pair of handles A tool for shaping spreadable material is shown as a plate with an opposite pair of finishing edges, one being straight, the other undulating. The lower edge of the tool is located between the finishing edges, and has an opposite pair of guide notches. Each of the notches can be pressed against the edge of the tray to regulate the tool's working depth.

An applicator tool (42) is provided for use with a robotic maintenance device (40) for 5 repairing damage (26) around a leading edge (22) of a wind turbine blade (20) on a wind turbine (10). The applicator tool (42) includes a tool frame (70) and a spatula (76) defining a flexible extrusion plate (78) that is configured to be engaged with an exterior surface (34) of the wind turbine blade (20), and a nozzle (84) that delivers a coating material (30) into a gap (112) between the extrusion plate (78) and the blade 0 (20). At least two nozzles (84) and corresponding fluid supplies may be provided to extend a working capacity of the applicator tool (42). The applicator tool (42) also includes a first chamfer arm (80) and a second chamfer arm (82) each configured to engage an outer surface (100) of the extrusion plate (78) adjacent a front edge (94) thereof to press the extrusion plate (78) against the exterior surface (34) of the blade 5 (20) at two specific engagement locations. The spatula (76) is configured to shape the coating material (30) into a shaped coating as the coating material (30) spreads in the gap (112) to thereby fill in and cover the damage (26) on the wind turbine blade (20), and the first and second chamfer arms (80, 82) are configured to limit spread of the coating material (30) beyond the two specific engagement locations 0 such that the shaped coating applied to the wind turbine blade (20) extends only between a first chamfer line (36) and a second chamfer line (38) on opposite sides of the leading edge (22). The applicator tool (42) also includes a vision system (160) configured to image the blade (20) to detect whether the first and second chamfer lines (36, 38) are located at expected positions to determine if any overfill or underfill 5 condition needs corrected. as well as a repair verification scanner (180) that detects a coating layer thickness of the shaped coating to further confirm whether a repair is performed as expected.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates on demand for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

An applicator for applying an adhesive film to a surface of an aircraft component includes an adhesive inlet for receiving adhesive from a source of adhesive, adhesive outlets for dispensing of adhesive therethrough, one or more reservoirs for receiving adhesive from a respective adhesive outlet, channels wherein at least two of the channels are configured to facilitate delivery of adhesive from the adhesive inlet to a respective, mutually-different outlet, and one or more adhesive-contacting surfaces for contacting adhesive dispensed from the adhesive outlets into the reservoir and for forming an adhesive film therefrom, the one or more adhesive-contacting surfaces being configured to be maintained in spaced relationship with a surface onto which an adhesive film is to be formed.

A method for depositing thin films using a nominally curved substrate. Drops of a pre-cursor liquid organic material are dispensed at a plurality of locations on a nominally curved substrate by one or more inkjets. A superstrate is brought down on the dispensed drops to close the gap between the superstrate and the substrate thereby allowing the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate is enabled to occur after a duration of time. The contiguous film is then cured to solidify it into a solid. The solid is separated from the superstrate thereby leaving a polymer film on the substrate. In this manner, such a technique for film deposition has the film thickness range, resolution and variation required to be applicable for a broad spectrum of applications.

A sliding device configured to perform a sliding process on a surface of an object to be slid includes a sliding part including sliding bodies each having a flat working surface; a first driving mechanism configured to regularly move the sliding bodies in parallel with the working surfaces of the sliding bodies; and a second driving mechanism configured to regularly move the sliding part in parallel with the working surfaces in a direction different from a moving direction by the first driving mechanism while the first driving mechanism moves the sliding bodies. This enables uniform supply of the sliding process material onto the surface of the object to be slid or clean the surface of the object to be slid.

A sealant dispensing system includes a sealant dispensing trowel having a handle and a trowel pad, where the trowel pad includes a trowel surface having an opening thereon through which sealant is configured to flow for applying sealant to a building surface. The trowel pad further includes a concave portion on the trowel surface with the trowel pad including a leading edge and a trailing edge with the concave portion extending to the trailing edge and with the opening on the trowel surface being disposed at the concave portion. In a particular configuration the concave portion is narrower at the opening and wider at the trailing edge, with the trowel surface including a flat portion and the concave portion being recessed relative to the flat portion and having a depth relative to the flat portion that is greater at the trailing edge than at the opening.
