    Abstract: A method and apparatus are provided for applying liquid to solid surfaces to which access may be limited or restricted. Liquid is continuously fed to an applicator where the liquid clings to a supporting surface to form a bead defining an outwardly exposed meniscus protruding beyond the applicator. The applicator is moved along the surface in a proximate relationship thereto which brings the protruding meniscus into contact with the surface to wipe liquid onto the surface, the applicator all the while being spaced a slight but noncritical distance from the surface. A portion of the liquid wiped onto the surface is immediately aspirated from the surface by suction applied through the applicator to leave on the surface a deposit of liquid controlled in quantity by the degree of aspiration accompanying the wiping of liquid onto the surface. The continuous aspiration of liquid from the liquid bead forming the protruding meniscus on the applicator prevents dripping of liquid from the applicator and functions in conjunction with continuous feeding of liquid to the meniscus to provide a continuous circulation of liquid on the applicator, even when it is awaiting usage, with no fouling of the applicator and no stagnation or deterioration of the liquid on the applicator.

    Abstract: A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end. The rod has an inner passage extending from the proximal end to the distal end. The proximal end has an inlet fluidly coupled to the supply. The inner passage terminates at an outlet at the distal end. The rod is insertable inside the shaft. An input device is operable for controlling a delivery of a predetermined quantity of the surface treatment agent from the supply. An applicator disposed at the distal end of the rod adjacent the outlet is engageable with the inner surface of the shaft for applying, upon activation of the input device, the predetermined quantity of the surface treatment agent to the inner surface of the shaft.
