A covering element is adapted to protect a paint-sensitive area wherein at least one opening is defined. The element includes a central stem having a distal portion intended to go through the opening, and a cap peripherally extending from a proximal portion of the central stem, for covering the area.

An aerosol creation system can include a pair of counter-rotating rollers configured to be positioned adjacent each other and define a nip between each other, a fluid source configured to provide a fluid to the nip, a driving element configured to drive the pair of counter-rotating rollers to rotate in counter rotation with respect to each other and cause the fluid to be drawn through the nip, and a collection shell configured to be positioned substantially around the pair of counter-rotating rollers, the collection shell having a nozzle configured to allow passage of the fluid from the nip.

A device for masking securing boreholes in rims with masking elements having a storage container for the masking elements, a pressure generation unit, a connection unit connected to the storage container and an at least substantially tubular discharge device, which is secured at one end to the connection unit and which has a discharge opening at the opposite end for discharging the masking elements. The discharge device has a tube wall in which a channel for conducting a fluid is formed, the channel being connected to the pressure generation unit. The tube wall consists at least partially of an elastic material, through which the channel runs or in which a cavity connected to the channel is formed, such that, when the pressure of the fluid is changed, the tube wall deforms and releases the clamping on the masking elements. The connection unit and the discharge device are formed preferably as one piece in a 3D printing method.

The electrical cover is a flexible, friction-held electrical cover that guards outlets from finish materials such as paint, spackling, and other foreign materials. The frictionally-held finish material electrical covers utilize specifically shaped features on the surfaces, such as negative draft, that contact the electrical components to increase the hold on the electrical device. Some of the shaped features of the frictionally-held covers also help minimize stress in the cover. The electrical covers are shaped with an arched rear surface that assists in minimizing edge warping when the electrical cover is positioned against the wall surface. Features are also molded into the parts to assist and strengthen the cover flatness once installed, and thus protect against the intrusion of finish material behind the cover.

A method of forming a cooling assembly in a turbomachine part is provided. The method includes placing an encapsulated diffuser insert partially into a hole in the turbomachine part. The encapsulated diffuser insert has an unobstructed central passageway with a generally circular cross-section at a first end and an elongated rectangular cross-section at a second end opposing the first end. The second end has a sacrificial cap. A coating step coats the turbomachine part to at least partially encapsulate the encapsulated diffuser insert in a coating. A removing step removes the sacrificial cap to enable air flow through the central passageway. The encapsulated diffuser insert remains in the hole of the turbomachine part and the coating, thereby providing the unobstructed central passageway with a generally circular first end and an elongated rectangular second end adjacent to an outer surface of the turbomachine part.
