Patent number: 10870086Abstract: Disclosed is a method and apparatus for manufacturing a continuous web of polymeric membrane and for continuous downstream processing of said web. The apparatus (10) comprises: a casting station (20) for casting the continuous web (M); a carrier (24) for carrying the web downstream; a membrane drier (30) downstream of the carrier, for drying the web; and a brushing station (40) downstream of the drier for brushing the web. Said drier is located immediately downstream of the carrier, and upstream of said brushing station. The apparatus (10) further includes an additional drying station (50) downstream of the brushing station (40). Brushing after drying retains more surfactant in the membrane which is useful for certain applications. In addition, initial drying eliminates virtually all solvents from the membrane, but leaves some non-solvent (e.g. water) within it, which in turn fixes the surfactant on the nitrocellulose fibers, which improves significantly the consistency and reproducibility of the membrane.Type: GrantFiled: March 24, 2016Date of Patent: December 22, 2020Assignee: Global Life Sciences Solutions Germany GmbHInventors: Marcel Thieme, Klaus Hochleitner, Suzana Kiel, Alexander Schenk, Wolfgang Thamm, Daniela Katarzynski, Georg Peter Danisch

Patent number: 9957945Abstract: Disclosed is an inventive method for controlling a corona ignition device of an internal combustion engine. A corona discharge, which ignites fuel in a combustion chamber of the engine, is generated by applying a voltage to the corona ignition device. An actual value that is characteristic of the nitrogen oxide concentration of the exhaust gas is compared with a setpoint value, and, if the actual value deviates from the setpoint value by more than a specified threshold value and the actual value is greater than the setpoint value, the voltage is reduced after the comparison.Type: GrantFiled: July 25, 2016Date of Patent: May 1, 2018Assignee: BorgWarner Ludwigsburg GmbHInventors: Steffen Bohne, Alexander Schenk

Method for controlling a corona ignition system of a cyclically operating internal combustion engine
Patent number: 9797365Abstract: A method for controlling a corona ignition system in which a corona discharge is produced at an ignition electrode by exciting a resonating circuit with an AC voltage produced by a high-frequency generator. The AC voltage is adjusted to a target value depending on an operating state of the engine. Combustion onset is determined by evaluating an electrical variable of the resonating circuit and the target value of the AC voltage is reduced by a predefined value following a predefined number of engine cycles or a predefined operating period. The determined combustion onset is evaluated in one or more engine cycles. The target value for the momentary engine operating state is then increased if, by evaluation of the combustion onset, it is found that a predefined requirement is no longer met. Otherwise, the reduced target value is stored as a new target value for the momentary engine operating state.Type: GrantFiled: March 9, 2015Date of Patent: October 24, 2017Assignee: BorgWarner Ludwigsburg GmbHInventors: Alexander Schenk, Torsten Schremmer, Georg Rixecker -
Patent number: 9787063Abstract: A sealing ring for a spark plug that has an external thread for screwing into an internal combustion engine, a collar and a thread undercut between the external thread and the collar. The sealing ring includes a ring-shaped solid sealing element made from metal. The sealing element has two planar annular sealing surfaces that are arranged parallel to one another. An annular retaining element composed of an elastomer for engaging in the thread undercut of the spark plug in a self-retaining manner is attached to the sealing element on the inner ring side thereof. Also included is a spark plug comprising such a sealing ring, and an internal combustion engine comprising such spark plugs.Type: GrantFiled: March 31, 2015Date of Patent: October 10, 2017Assignee: FEDERAL-MOGUL IGNITION GMBHInventors: Werner Niessner, Alexander Schenk
