Publication number: 20220396877Abstract: A gas inlet element for a CVD reactor includes a cylindrical main body, which together with an outer wall, forms a gas outlet face. The outer wall surrounds at least one gas distribution chamber. A plurality of gas outlet openings originating in the gas distribution chamber open out into the gas outlet face. A cooling device includes a plurality of cooling channels running adjacently but separately in the outer wall, and the gas outlet openings extend between the cooling channels.Type: ApplicationFiled: November 17, 2020Publication date: December 15, 2022Inventors: Marcel KOLLBERG, Benjamin David WRIGHT, Merim MUKINOVIC, Barry O'NEIL, Marc PLUMMER

Patent number: 9517627Abstract: A cap 13, 15, for the print face 9 of a drop-on-demand ink jet printer moves between a closed position, in which it covers the print nozzles on the print face 9, and an open position in which the print nozzles are uncovered, without requiring movement of the print face 9. In the open position, the cap is recessed relative to the front surface 21 of the printhead. For at least part of the movement of the cap, it is further forward than the print face 9, so that it does not slide across and damage the print nozzles. The drop-on-demand ink jet printer may be used to print onto objects 3 conveyed past it, for example on a packing line. The cap 13, 15, does not obstruct the path of the objects 3 even if they pass very close (e.g. 0.5 mm) to the print face 9 because its uncapped position is further back than the front surface 21 of the printhead.Type: GrantFiled: April 7, 2016Date of Patent: December 13, 2016Assignee: Linx Printing Technologies LtdInventors: Marc Plummer, Graham Thomas

Patent number: 8833915Abstract: An ink/air separator for an ink jet printer has one or more plates 77, 79, 81, 83 over which an ink/air mixture can spread. Preferably there is more than one plate, and the mixture overflows from one plate to the next. Preferably adjacent plates are spaced so that as the mixture passes between two plates it contacts the surface above it as well as the surface below it. The plates may be separated by a gap of 10 mm or less, e.g. a gap of 2 mm to 5 mm, where they overlap Preferably some or all of the plate surfaces contacted by the mixture are roughened. Interaction between the ink/air mixture and the plate surface tends to slow the flow of very small air bubbles and encourage them to accumulate and/or merge, so that they separate from the ink more quickly than individual small bubbles. The ink/air separator may be connected in the path of unused ink returned from the gutter 27 of a continuous ink jet printer to an ink tank 39, or may be placed inside the ink tank 39.Type: GrantFiled: June 15, 2011Date of Patent: September 16, 2014Assignee: Linx Printing Technologies LtdInventor: Marc Plummer
