Abstract: Liquid leak sensor, apparatus for detecting liquid leaks, and applications thereof, for sensing (detecting), and providing timely notification of, liquid leaks in a variety of commercial applications, via automatic (real time), efficient, accurate, reliable, and cost effective means. Particularly applicable for sensing (detecting) liquid leaks at critical connection (junction) points in liquid-containing conduits. Liquid leak sensor includes: a sheet of flexible non-conductive fabric material, configured for wrapping around, or placing under, a liquid-containing conduit; and a liquid sensitive electrically open electrical circuit (of wires, fibers) interlaced throughout the fabric sheet, and configured for facilitating sensing of liquid when leaked from the conduit and contacting the fabric sheet, via leaked liquid effecting electrical closure of the electrical circuit.

Abstract: A method of tensioning a print medium on a drum comprising: supporting the medium on the drum; rotating the drum; and applying a gaseous flow to the medium on the drum, the gaseous flow having a major component that is tangential to the drum and in a direction that is opposite to the linear direction of the surface of the drum.

Abstract: A small footprint drum inkjet printer having a print head consisting of a number of print head arrays; a substrate carrier preferably in the form of a drum with vacuum orifices therein, a substrate loading cassette capable of movement, relative to the drum, in at least one direction; a substrate unloading cassette capable of movement, relative to the drum, in at least one direction, and a curing radiation source having a reflector which extends along the drum surface.

Abstract: A carrier for an array comprising a plurality of print heads, comprises an elongate bar having an ink conduit extending through the bar in a longitudinal direction. The carrier also comprises a print head receiving area adapted to receive or mount the plurality of print heads, and a heat transfer fluid conduit extending through the bar in a longitudinal direction. The carrier is arranged so that each print head received or mounted in the print head receiving area is in fluid communication with the ink conduit, wherein the heat transfer fluid conduit is disposed adjacent both the ink conduit and the print head receiving area. The carrier may comprise two ink conduits and two heat transfer fluid conduits. Heat transfer fluid may in use be conducted along the first and second heat transfer conduits in opposite directions.

Abstract: The present invention is concerned with a drum printer in which the loading and unloading of printing medium onto and off a drum of the printer is performed without interrupting or decelerating the drum rotation and the printing process.
