A method for monitoring a nozzle mouthpiece for placing on a nozzle for spraying materials, in particular dispersions, emulsions or suspensions.

A fluid ejection device that includes a housing, a fluid reservoir disposed in the housing and a fluid ejection head. A revolving maintenance station that includes an ejection head wiper and an ejection head capping device is movably attached to the housing and is configured for rotation to selectively position the ejection head wiper or the ejection head capping device adjacent to the fluid ejection head.

A cleaning device for cleaning a dispensing nozzle assembly of a beverage dispenser is disclosed. The dispensing nozzle assembly may include a macro-ingredient/diluent outlet and a number of micro-ingredient outlets surrounding the macro-ingredient/diluent outlet. The cleaning device may include a handle, a head end rotatably attached to the handle, a guidance protrusion extending from the head end, a first set of bristles extending from the head end and surrounding the guidance protrusion, and a second set of bristles extending from the head end adjacent to the first set of bristles.

A combination sod cutting and sprinkler cap removal tool includes a socket having a cavity and outer surface extending between proximal and distal ends, a cutting means disposed circumferentially about the distal end, an internal gear formed within the cavity, and a removable rotating means insertable into the cavity and configured to rotatably engage and be axially arrested by the internal gear whether the rotating means is inserted through the proximal end or the distal end. Interior gear teeth of the internal gear have both inner and outer engagement surfaces. When inserted through the proximal end, the rotating means engages the outer engagement surfaces to configure the distal end of the tool for cutting sod by rotation of the cutting means. When the rotating means engages the internal gear through the distal end, the proximal end of the tool is configured for removing a sprinkler cap by engaging the inner engagement surfaces with gripping surfaces of the cap.

A self-cleaning filter apparatus includes a filter unit and a plunger unit. The filter unit includes a screen device; and a filter unit housing that houses the screen device. The plunger unit includes a rod end housing coupled to the filter unit housing; a plunger rod with a first plunger rod end positioned within the rod end housing and a second plunger rod end within the filter unit housing; and a plunger assembly secured to the second plunger rod end. During a first filter cleaning event segment, the plunger rod is configured to translate between a nominal position in which the plunger assembly is proximate the first screen device end and a cleaning position in which the plunger assembly is proximate the second screen device end. The plunger rod is configured to dislodge, at least in part, debris from within the screen device during at least the first filter cleaning event segment.

A vaporizer includes a housing that comprises a first end and a second end. An atomizer is disposed at the first end of the housing. A mouthpiece is disposed at the second end of the housing. A channel is disposed inside the housing and extends from the first end to the second end. The channel is configured to permit air flow from the atomizer to the mouthpiece. The channel includes a cross section that is substantially non-circular.
