A locking tool extension apparatus and painting tool assembly for preventing threaded tool handles from loosening on an extension pole includes a plurality of painting tools having a threaded female handle aperture. An extension pole has a threaded male pole end coupled to a pole top side. A locking tool extension apparatus comprises a sleeve body having a threaded female receiving. The female receiving aperture selectively receives the threaded male pole end of the extension pole. A threaded male extension end is coupled to the sleeve body. The male extension end is selectively engageable with the threaded female handle aperture of the tool handle. A first spring lock washer is coupled to the sleeve body. The first spring lock washer prevents the tool handle from unintentionally loosening on the male extension end.

Environmental sanitizing device including a frame housing a disinfectant liquid reservoir and supporting a nozzle, the nozzle associated with a generation system of an air flow within which a plurality of disinfectant liquid particles are suspended to sanitize a closed environment in which the device can be positioned; the nozzle is movable with respect to the frame, and associated with positioning system controlled by a control unit for orientation of the nozzle with respect to at least two mutually perpendicular axes, preferably around a first vertical axis and around a second horizontal axis to automatically orient the nozzle in desired direction with respect to the frame during a sanitization step, the nozzle coupled with at least one distance detector able to determine distance between the nozzle and an obstacle facing the nozzle.

A sprinkle is provided with an adjustable housing. The housing includes two components that are adjustable relative to one another. One of the housing components supports the sprinkler internals so that the can be raised to ground level.

A method of controlling application of at least one material to a substrate is provided. The method includes configuring at least one array having a plurality of micro-applicators such that a subset of the micro-applicators is individually addressable to apply the at least one material to the substrate. Individually addressing the subset of micro-applicators provides control of a pattern width of a coating applied to a substrate, control of a flow rate of the material applied to the substrate, control of an angle of application of the material to the substrate, control of which and how many materials are applied to the substrate, and combinations thereof.

A spray head body extension that is screwed onto the upper end of a spray head body after the cap is removed. The cap is then reinstalled on the extension to raise the effective height of the a spray head body and its spray pattern. The spray head body extension permits fast, easy raising of a sunken in-ground spray head without having to dig below the spray head's water supply. A one-piece embodiment uses a compressible gasket to enable the extension to be tightened to the body until the internal guide splines of both the extension and body are aligned. A set screw can be employed to preserve alignment when the cap is reinstalled. An alignment tool helps align the splines of the extension to the body during installation. A multi-piece embodiment enables the extension to be aligned to the body before a separate collar nut is tightened.
