A syringe attachment/detachment mechanism enables a syringe to be easily attached to and detached from a discharge device without causing twisting of a tube, and enabling the syringe and an adapter to be fixedly held in a desired orientation. In the syringe attachment/detachment mechanism and the device provided with the mechanism, the mechanism being adapted for a discharge device to which a syringe including an attachment part and an upper connection part is attached through screwing, the attachment part includes an inner cylindrical portion having a small-diameter opening, an outer cylindrical portion surrounding the inner cylindrical portion, and a screw portion. The attachment/detachment mechanism includes a support member including a cylindrical insertion portion into which the inner cylindrical portion is inserted, and having a channel formed therein for communication between the small-diameter opening and a nozzle of the discharge device. A rotation member includes a screw portion.

An adhesive dispensing system and method of dispensing liquid material are disclosed. The adhesive dispensing system includes an adhesive dispensing module receiving hot melt adhesive through the inlet at a low pressure and rapidly developing high pressure at an outlet to thereby jet the hot melt adhesive therefrom. The system also includes a pressure container containing a supply of hot melt adhesive and configured to melt or maintain a heated temperature of the hot melt adhesive. A low pressure liquid passageway communicates between the adhesive dispensing module and the pressure container. The system also includes a pressurized air source in fluid communication with the adhesive dispensing module to operate the adhesive dispensing module by moving a piston to generate high pressure at the outlet of a nozzle for jetting hot melt adhesive as a discrete volume toward a substrate.

In an example, a method including dispensing a liquid onto a first portion of a surface of a substrate and dispensing a solution comprising colloidal spheres onto a second portion of the surface of the substrate. The method additionally includes agitating the colloidal spheres to disperse the colloidal spheres along the first portion and the second portion of the surface of the substrate and directing air flow above the colloidal spheres inducing rotation of the colloidal spheres. In another example, a method includes positioning a retaining ring on a surface of a liquid above a substrate below the surface of the liquid and dispensing a solution comprising colloidal spheres onto the surface of the liquid within a surface area of the retaining ring. The method further includes agitating the surface of the liquid and the colloidal spheres to disperse the colloidal spheres along the surface area of the retaining ring.

A method or applying a fast curing epoxy traffic marking composition is provided in which curing agents are coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface.
