Fastener-coating tools comprise a non-permeable body and a permeable body that laps over at least a portion of an outer surface of the non-permeable body, laps over all of a terminal surface of the non-permeable body, laps over at least a portion of an inner surface of the non-permeable body, spans an internal cavity of the non-permeable body, and defines a fastener cavity that is sized and shaped to receive a portion of a fastener assembly to be coated.

Paint tester and methods of testing paint using the paint tester. The paint tester having a sealed receptacle containing paint, a foam applicator, and a seal cutter. The methods comprising rotating the seal cutter with respect to the receptacle until one or more teeth will cut into and break a seal on the receptacle, applying inward pressure to an exterior surface of a receptacle wall causing paint to flow from the receptacle through a channel exit of the receptacle, through a conduit defined in the seal cutter, out a conduit exit encircled by crenulations, through pores in the applicator, and onto an exterior surface of the applicator, and touching the exterior surface of the applicator to a surface upon which paint is desired.

Described are metering dispensers having a body configured to hold a flowable composition in a chamber, a drive screw coupled to the body, and a plunger threadingly coupled to the drive screw. The plunger includes at least two annular lips that form a fluid seal with the chamber as the plunger travels along the drive screw through the chamber. A base is rotationally coupled to the body with a cam that contacts at least one tab extending externally from the body so that the tab enters at least one low point on the cam by traveling over a trailing edge of the low point, and the trailing edge then prevents the tab from exiting the low point in the direction of the trailing edge.

Nozzles are provided, for applying setting resins onto the edge of a panel, in some embodiments the cut edge of a panel such as a honeycomb panel. The nozzle comprises a connector portion and an application head, wherein the application head comprises: a) a supporting wall, and b) a curved finish wall joining the supporting wall along an edge at an angle of greater than 92 degrees and less than 120 degrees. In some embodiments, the curved finish wall has a curve radius which remains between 1.0 and 7.0 cm throughout the length of the curved finish wall. In some embodiments, the curved finish wall has a trailing edge profile which is smoothly curved and a leading edge profile which is scalloped. In addition, methods of applying a setting resin onto the edge of a panel are presented.

One general aspect includes a liquid dispenser with a mount having a mount aperture. A liquid flow path assembly is removably secured to the mount and has an inlet configured to receive liquid, an outlet configured to dispense liquid and a passageway fluidly coupling the inlet to the outlet. A third aperture apart from the inlet and the outlet is fluidly coupled to the passageway and forming a valve guide. The liquid flow path assembly is disposed on the mount to align the third aperture with the mount aperture. An elongated valve has a valve stem guided by the valve guide and extends through the third aperture and the mount aperture. A latch assembly secures the liquid flow path assembly to the mount.

An applicator tool (40) for repairing damage (26) to a wind turbine blade (20) includes a spatula (42) including a flexible extrusion plate (44) and one or more spacers (60, 106) positioned proximate an inner surface (58) of the extrusion plate (44). The one or more spacers (60, 106) are configured to define a gap between an outer surface (34) of the wind turbine blade (20) and the inner surface (58) of the extrusion plate (44). A feed tube (86) is provided for supplying a coating material to the spatula (42), wherein the spatula (42) is configured to shape the coating material into a coating (30) over a damaged area (26) of the wind turbine blade (20).

A discrete dispensed product comprising a first portion; and a second portion at least partially surrounding the first portion provides a premium and distinct appearance to consumers.

Various aspects and embodiments are directed to a precision dispenser that is hand held and constructed and arranged to receive and release a variety of glue cartridges. In various embodiments, the adhesive cartridges include precision tips that provide, for example, flat even bead with little or no spill or drip. Other precision tips can be constructed and arranged for use with the precision glue gun. In some examples, the precision tips can be tailored to the specific adhesive contained in the cartridge.

An installation system to fabricate the multiple glazing units at the installation site is provided. The installation system includes a primary glazing unit, a secondary glazing unit, a spacer element, a primary sealant, a fixture, a secondary sealant and a dispenser. The installation system includes a fixture to apply the primary sealant on the spacer element. The installation system also includes a dispenser to apply the secondary sealant to a clearance between the primary glazing unit and the secondary glazing unit.
