Patent number: 11473681Abstract: A globe valve (e.g. Flow-To-Open valve) can include an inlet opening with a circular shaped opening cross section defining a valve axis, a globe valve member movable in a vertical direction transversely to the valve axis and connectable, via a valve rod, to an actuator for actuating the globe valve member, and a passage opening with a circular-shaped passage opening cross section. The globe valve member closes the passage opening at a lowest actuating position, in the vertical direction, and a flow channel extending from the inlet opening to the passage opening defines a flow cross section. The surface size of the flow cross section decreases in a first section from the inlet opening, in a flow direction, to a transition point. The flow cross section, in the first section, is continuously oval shaped and the first section of the flow channel is continuously inclined downwards in the vertical direction.Type: GrantFiled: June 7, 2020Date of Patent: October 18, 2022Assignee: Focus-On V.O.F.Inventors: Kavreet Bhangu, Andre H. Boer, Jonas Waid, Michael Merscher, Marcel Krueger

Patent number: 7957829Abstract: A method for positioning or guiding at least one arbitrary print head or a printing unit having at least one pressure nozzle for the imprinting of thin substrates such as wafers at a defined distance above the surface of the substrate, which is to be provided on a support like a paddle or printing table. Distance sensors continuously acquired distance measurements to the surface of the substrate which is to be imprinted. An adjustment of the print head up to 6 degrees of freedom is ensured by actuators in such a manner that the section of the opening of the pressure nozzle of the print head can be adjusted so as to be coplanar to the section of the surface of the substrate which is to be imprinted. The print head is thus maintained or readjusted so as to adjust the section of the opening of the pressure nozzle of the print head to the surface of the substrate which is to be positioned on the support table so as to be coplanar and so as to maintain the coplanar position during the printing process.Type: GrantFiled: December 17, 2008Date of Patent: June 7, 2011Assignee: Jonas & Redmann Automationstechnik GmbHInventors: Stefan Jonas, Lutz Redmann, Michael Merscher, Claudio Uriarte
