A mud pumping apparatus that can be removably coupled to a container the mud was originally provided in when first obtained by the user. The mud may be mastic, mortar, grout, joint compound, spackle, or the like. The apparatus may be sized to be used with various standard sized containers, and adjustably powered and controllable to be used with different types, consistencies, and viscosities of spreadable material.

A fluid dispensing system includes a housing, an inertial measurement unit supported by the housing and operable to sense linear and rotational acceleration of the housing, a nozzle supported by the housing operable to expel a fluid, a pressure source in fluid communication with the housing and the nozzle and operable to pressurize the fluid, a valve positioned fluidically upstream from the nozzle and operable to regulate fluid flow to the nozzle, and a controller in operable to receive an application value relating to a predetermined volume of fluid to be applied to a surface of an article, to receive movement data relating to the linear and rotational acceleration of the housing sensed by the inertial measurement unit, and to regulate the valve based on the movement data and the application value.

A lateral applicator kit for a pipe has a first and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral walls of a pipe. The first unit receives primer through a first supply engagement feature, which is in fluid communication with a first material reservoir internal to the first application unit and further in fluid communication with an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The application receptacle has at least one first material applicator connected across at least one first application opening through which primer is absorbed and distributed to the pipe. The application receptacle has a tapered, flexible applicator wall for adaptably accommodating a range of pipe diameters. The second unit is similarly but inversely configured to adaptably apply primer to the interior surface of a fitting.

The invention relates to a tool (1) for applying liquid agent such as, for example, an insulating foam, an adhesive, or paint to the mantle surface of a circular-cylindrical object (10), comprising a tool head (2) having an axially through hole (3) with a substantially circular cross-section. The tool head (2) comprises an inner flange (8), an outer flange (16), a distribution chamber (12) running around the inner flange (8) and that comprises at least one outlet (13; 23; 33) distributed around the through hole (3). An asymmetrical restriction is arranged at the outlet (13) so that the outlet is restricted where the pressure is as highest (14). The invention also relates to a method for applying an agent around a circular-cylindrical object (10) with the tool (1).

Chemically impregnated applicators used to provide hydrophobic surfaces on chemical mechanical polishing system components and related application methods are shown. A method of forming a hydrophobic coating on a surface of a polishing system component includes cleaning the surface of the polishing system component to remove a polishing fluid residue therefrom and applying a hydrophobicity causing chemical solution to the surface of the polishing system component.

A method and apparatus for applying sealant. The apparatus may comprise a shaping portion, a centering portion, and a support system. The shaping portion may have a cavity configured to receive a fastener system and receive a sealant. The centering portion may have a channel configured to position the shaping portion in a desired position around the fastener system when the fastener system is received in the cavity. The support system may be configured to maintain the desired position of the apparatus.
