Abstract: Apparatus is described comprising a treatment chamber, a pump, a condenser and a secondary chamber. The treatment chamber comprises an interior into which an article to be treated can be disposed. The condenser, the pump and the secondary chamber are is in fluid communication with the treatment chamber in a closed loop to form a vapor extraction part of the apparatus. The apparatus may comprise a controller to control the operation of the apparatus automatically.

Abstract: In an example of the disclosure, a cleaning system for a printhead includes a web of material movable in a web direction. The web has a first side for wiping a printhead face. The cleaning system includes a dispensing apparatus to dispense a liquid upon the web. The cleaning system includes a scraper element for scraping liquid from the web and includes a collector element with a trough. The collector element is to cause collection of liquid scraped from the web to collect in the trough. The cleaning system includes a pusher element to push against the second side of the web and thereby cause the first side of the web to wipe the printhead face.

Abstract: In an example of the disclosure, a printhead is caused to spit a liquid into a main cavity of a container. The container includes an overflow pocket for collecting liquid that has overflown from the main cavity. A sensor is caused to detect whether liquid is present in the overflow pocket. Responsive to sensor detection that liquid is present in the overflow pocket, a warning or instruction message is caused to be sent for user consumption.

Abstract: An internally threaded plastic closure in accordance with the present invention includes an array of axially extending, circumferentially spaced internal ribs which intersect the internal thread formation of the closure. By this arrangement, vent passages are defined between adjacent ones of the internal ribs, thus providing the closure with desirable gas venting characteristics, while avoiding the provision of vent grooves extending into the inside surface of the closure side wall, which can undesirably impair the strength of the side wall. By the present construction, the amount of polymeric material from which the closure is formed can be desirably reduced, while maintaining the desired dimensional characteristics of the closure, to facilitate use with existing containers and high-speed capping equipment.
