Patent number: 12203507Abstract: A fluid guide assembly for a friction disk clutch comprises an inner disk carrier having a carrier portion, a shoulder portion, and a shaft portion. The carrier portion has a connecting structure for receiving inner disks in a rotationally fixed and axially movable manner; and a fluid guide element which is fixedly connected to the inner disk carrier and which comprises an annular catching portion in which inflowing fluid can be caught, and a plurality of circumferentially distributed tab portions which extend in the axial direction and which each have a radial through-opening. The inner disk carrier has, directed radially outwardly, a plurality of longitudinal grooves which extend axially from the shoulder portion into the carrier portion and which are covered by tab portions of the fluid guide element.Type: GrantFiled: June 23, 2021Date of Patent: January 21, 2025Assignee: GKN Automotive LimitedInventors: Kurt Thomaser, Peter Raffin, Thomas Messner, Hanspeter Putzer

Publication number: 20060231769Abstract: An electron multiplier detector includes cathode structure defining a plurality of spaced co-planar impact surface segments on which particles impact. These surface segments each have a finite probability of generating at least one electron for each impacting particle having predetermined characteristics. The detector further includes respective sets of electron multiplication dynode segments associated with the impact surface segments, the sets being arranged as substantially parallel arrays extending behind the impact surface segments, and respective means for generating electrostatic and magnetic fields in a space extending from the impact surface segments past the dynode segments, whereby respective streams of electrons cascade and multiply successively along the arrays of dynode segments. Collector structure is provided to receive and detect the streams of electrons downstream of the last dynode segments in the arrays.Type: ApplicationFiled: March 22, 2006Publication date: October 19, 2006Inventors: Richard Stresau, Kevin Hunter, Wayne Sheils, Peter Raffin, Yair Benari

Patent number: 6982428Abstract: Electron focussing apparatus includes a cathode plate defining an impact surface on which particles impact, which surface has a finite probability of generating at least one electron for each impacting particle having predetermined characteristics. The apparatus also has an electron receiving element, and respective means for generating electrostatic and magnetic fields in a space extending from the impact surface to the electron receiving element. The means for generating the electrostatic and magnetic fields are configured whereby the E/B2 ratio adjacent the electron receiving element is smaller than adjacent the impact surface, whereby to decrease the radius of curvature of the electron trajectories adjacent the electron receiving element relative to adjacent the impact surface and to thereby focus the electron trajectories in at least one dimension.Type: GrantFiled: January 16, 2004Date of Patent: January 3, 2006Assignee: ETP Electron Multipliers Pty LtdInventors: Richard Stresau, Kevin Hunter, Wayne Sheils, Peter Raffin, Yair Benari
