Publication number: 20020175304Abstract: There is described a method of operating an actuator which is used to open and close valves in pipelines. In order to avoid pressure surges and resonances during the closing operation in pipelines to be shut off, the closing operation of the valve i subdivided into two closing phases (S1 and S2). During the first closing phase (S1), the actuating element is moved at maximum actuating speed down to a predefinable position (P) of the actuating element, starting from the open state of the valve. From this position (P), the actuating speed of the actuating element is reduced continuously and steplessly with a predefinable gradient.Type: ApplicationFiled: May 9, 2002Publication date: November 28, 2002Applicant: ABB Patent GmbHInventors: Herbert Moeller, Marcel Schilg

Publication number: 20020020211Abstract: Methods for testing a completely or partially assembled combustion engine have heretofore made use of orifices with preset flow cross-sections, with the result that it was not possible for pressure arising in a combustion chamber to be adapted to varying measuring cycles. In order to make an optimum air-mass flow available to a particular measuring step, the flow cross-section of the orifices is adjusted as a function of a test program. The optimum air-mass flow is also made possible by subjecting the combustion chamber to a pressure which is greater than the ambient pressure of the combustion engine.Type: ApplicationFiled: July 6, 2001Publication date: February 21, 2002Applicant: ABB Patent GmbHInventors: Robert Lambertz, Thomas Thissen

Patent number: 6347497Abstract: Although hitherto known machine frameworks of O-form are sufficiently stable, they can only be installed subsequently in an assembly station if a conveying belt is disengaged, a belt section is removed, a framework is assembled with the removed belt section, and the two are reintroduced together into the assembly station. Although the machine framework of C-form construction can subsequently be pushed onto the transporting system formed of the conveying belts, it is necessary, for stability reasons, for them to be made of considerably thicker material than the O-frameworks. The intention is therefore to specify a process, for constructing an assembly installation, for which a machine framework of O-form is sufficient and which nevertheless contains the subsequent-fitting advantages exhibited by the C-form. For this purpose, transverse struts of the machine framework are removed. They are fastened on the underside of a conveying-belt section.Type: GrantFiled: September 8, 1998Date of Patent: February 19, 2002Assignee: ABB Patent GmbHInventor: Gerhard Simonis

Patent number: 6346294Abstract: A process for producing a coating on components having peripheries to be placed in direct contact with vaporous media. Such peripheries are wetted over part or all of their surface with a film of liquid when the vaporous media are changed from the vapor state into the liquid state by phase transition. Such films of liquid increase the thermal resistance, for example, of the components. In order to avoid such wetting, the peripheries of each component are roughened. A coat of a non-wettable, amorphous carbon is then applied to the peripheries, at least in regions thereof.Type: GrantFiled: April 28, 1999Date of Patent: February 12, 2002Assignee: ABB Patent GmbHInventors: Harald Reiss, Manfred Wetzko
