In one embodiment, a feed pump of a tube pump type is used for supplying a processing liquid. The tube pump has a squeezing member that moves from a first axial position of a tube at which the squeezing member starts pinching of the tube, to a second axial position at which the squeezing member leaves the tube after feeding the processing liquid toward an ejecting part such as a nozzle. Only one pinched part pinched between the squeezing member and a guide member is formed between the first axial position and the second axial position of the tube, and the only one pinched part moves along the axial direction of the tube, during feeding of a dose of the processing liquid toward the ejecting part.

In response to the objection raised, please make the following changes to the Abstract, On line 3, delete the words The present invention relates to and replace with A. On line 9, delete the last sentence, The system can be adapted for use with a roller.

A spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head attached to the adapter body is attached at the upper portion of the adapter body. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper portion and the lower portion of the adapter body.

The invention is a roller liquid compound applicator configured to attach to the threaded neck of a liquid supply container for the purpose of applying a coating of a liquid compound to a target surface, and includes: a U-shaped roller support frame including a substantially cylindrical dispenser coupling cap and a drip guard attached to the dispenser coupling cap, the dispenser coupling cap having a threaded cavity configured for mating with the threaded neck of the liquid supply container; and a liquid compound roller sleeve secured to the roller support frame.

A storage container for a cylindrical tube of viscous construction material includes a body dimensioned to receive a cylindrical tube of viscous construction material. A nozzle enclosure is attached to a top end of the body and is dimensioned to receive a nozzle of a cylindrical tube of viscous construction material. A plug is positioned in the nozzle enclosure and dimensioned to fit into an inner diameter of the nozzle of the cylindrical tube of viscous construction material. A gasket is positioned between the body and the nozzle that substantially prevents air in the body from entering into the nozzle enclosure. A base seals the cylindrical tube of viscous construction material in the body.

A paint applicator, kit and methodology for using the same is disclosed. For example, paint applicator that allows a user to load a desired amount of paint, such as a water based other low VOC paint, into the paint applicator and an advancement mechanism that dispenses paint at a rate controllable by the user is disclosed. The advancement mechanism can include system that translates a rotational force applied to an end cap of the applicator into a linear that advances a piston which in turn applies paint to an applicator portion. The paint may be reusable or may include a ratchet system that allows for only one time use. methodology and kit can incorporate a syringe for loading paint into the paint applicator, reducing the loss of paint through spilling.

A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft extending longitudinally along a shaft axis and having an axial shaft length to be treated. The device includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end with an applicator disposed at the distal end. The elongated rod is insertable inside the hollow engine shaft. An applicator is disposed at the distal end of the elongated rod and wetted with the surface treatment agent. The applicator is engageable with the inner surface of the hollow engine shaft for applying the surface treatment agent to the inner surface of the hollow engine shaft. A pair of markers are disposed on the elongated rod and axially spaced apart from one another at a first axial distance corresponding to the axial shaft length.

An apparatus for activating a chemistry disposed upon a target structure includes a handle; a structure contacting element rotatably attached to the handle and adapted to roll without slipping upon a target structure; and a radiant energy source having an emissive outlet at least partially within the structure contacting element wherein said contacting element is at least partly transparent or translucent to said radiant energy.
