Abstract: A modular fluid delivery assembly is provided. The modular fluid delivery assembly comprises a fluid conduit. The modular fluid delivery assembly also comprises an electrical heating element disposed within the fluid conduit. The electrical heating element is configured to provide a heat source within the fluid conduit. The modular fluid delivery assembly also comprises a connection assembly, located proximate an end of the modular fluid delivery assembly, coupled to the heating element and the fluid conduit. The connection assembly is configured to provide a hydraulic coupling to the fluid conduit, and to provide an electronic coupling to the electrical heating element.

Abstract: A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

Abstract: A mixer for a plural component spray gun is presented. The mixer has a mixer body comprising a mixing chamber with an outlet. The mixer also has a first fluid component inlet, coupled to a first fluid conduit, configured to introduce a first fluid component into the mixing chamber. The mixer also has a second fluid component inlet, coupled to a second fluid conduit, configured to introduce a second fluid component into the mixing chamber. The first and second fluid component inlets are offset with respect to a centerline of the mixing chamber and positioned such that a first fluid flow from the first inlet is directed toward the outlet, and a second fluid flow from the second inlet is directed toward the outlet.

Abstract: A paint applicator for use in spreading paint over a surface. The paint applicator includes a roller assembly, tubing, and a pump assembly. The roller assembly has a handle portion that is suitable for holding by a user, an arm portion extending from the handle portion, and a roller core removably attachable to the arm portion for rotation with respect to the arm portion. The roller core is adapted to receive a paint applicator thereover. The tubing has a central passage extending therethrough. The pump assembly conveys paint through the tubing to the roller assembly. A method and a corner paint applicator are further included.

Abstract: A heat gun having a fan assembly for use therein having a flow straightener to reduce turbulence in air passing through the fan assembly. The fan assembly also includes a blower housing with a reduced diameter outlet, a relatively large diameter radial flow impeller, and an electric motor to rotate the impeller. The flow straightener includes a plurality of vanes, and curved radially interior and exterior walls. The motor includes apertures in upstream and downstream ends and apertures in a cylindrical sidewall.

Abstract: A cordless electric powered caulking gun for pressurizing a tube of highly viscous substance includes a ball drive rod having a helical thread and a keyway, an electric motor and gear reducer coupled to a spur gear keyed to the ball drive rod, a cylindrical ball retainer having a plurality of pockets located on a helical locus aligned with the helical thread, a plurality of balls with one ball in each pocket of the retainer, a ball drive nut telescoped over and selectively axially moveable between a first and second position with respect to the ball retainer, and a trigger coupled to the ball drive nut via a spring to urge the nut from the first position to the second position when the trigger is actuated. The trigger further has a bearing surface and axial contact with the ball drive nut to force the nut to the first position when the trigger is released to a deactuated position.
