Abstract: A printing apparatus and method. The printing apparatus is for impinging liquids from at least two liquid sources. The apparatus comprises a first jet actuator configured to dispense a first liquid from a first liquid source and a second jet actuator configured to dispense a second liquid from a second liquid source. The apparatus further comprises an adjustment element configured to adjust a trajectory of at least the first liquid dispensed from the first jet actuator such that the first liquid impinges the second liquid dispensed from the second jet actuator.

Abstract: The invention discloses a duct section for an air distribution system, the duct sections including an elongate frame having two opposed flange members each having an opening forming an air passage therein. A plurality of the duct sections are able to be joined together through the flanges to form an air passage of desired length. Each duct section is lined with a thermal insulating material to provide a thermally insulating lining to the air passage, the ends of the lining being at least flush with the end faces of the flanges so that when adjacent duct sections are secured together, the thermal insulation lining of adjacent duct sections is arranged to provide a continuous insulating lining of the air passage.

Abstract: The invention discloses a duct section 1, 2 for an air distribution system, the duct sections including an elongate frame 2, 4, 24 having two opposed flange members 5, 6 each having an opening forming an air passage therein. A plurality of the duct sections are able to be joined together through the flanges to form an air passage of desired length. Each duct section 1, 2 is lined with a thermal insulating material 8, 25 to provide a thermally insulating lining to the air passage, the ends 11 of the lining 8 being at least flush with the end faces of the flanges so that when adjacent duct sections are secured together, the thermal insulation lining 8 of adjacent duct sections is arranged to provide a continuous insulating lining of the air passage.
