Patent number: 9833387Abstract: The present invention relates to a kit for indirect production of composite inlays, comprising a polymerizable material for production of a dental model, a polymerizable material for production of an inlay, a polymerizable material for luting of a crosslinked and non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity. Also disclosed is a polymerizable material for increasing the bond strength between the polymerizable material for luting of a crosslinked non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity, and the hard substance of the tooth, and an acid solution for surface etching of the hard substance of the tooth. The invention further relates to methods for producing a composite inlay.Type: GrantFiled: October 7, 2013Date of Patent: December 5, 2017Assignee: VOCO GmbHInventors: Manfred Thomas Plaumann, Klaus-Peter Hoffmann, Tobias Bloemker, Alexander Willner

Patent number: 9421152Abstract: A dental material, a dental mixture or a dental multi-component system for making the material of or core for a temporary superstructure for a dental implant by polymerization hardening, consisting of one, two or a plurality of polymerizable (meth)acrylates, and optionally further constituents. The dental material, the dental mixture or the multi-component system is hardenable to a product, and the maximum compressive modulus is 420 MPa, and is used in therapeutic treatments for accelerating the osseointegration of dental implants, in particular according to the method of progressive bone loading. Also described are temporary superstructures and cores themselves, and a temporary dental prosthesis, a kit for making a plurality of temporary superstructures for a dental implant or a plurality of cores for temporary superstructures for a dental implant. A corresponding method of preparing a temporary superstructure or a core is also described.Type: GrantFiled: January 24, 2012Date of Patent: August 23, 2016Assignee: VOCO GMBHInventors: Reinhard Maletz, Tobias Blömker, Klaus-Peter Hoffmann, Manfred Thomas Plaumann

Patent number: 6669276Abstract: A sliding roof system for a motor vehicle comprises at least one cover part and a cover support to which the cover part is mounted. The system further comprises a guide rail on which a hook-out slot is provided and a carriage which can be shifted in the guide rail. An adjustment slot is provided on the carriage and is engaged by a hook-out pin which is mounted to the cover support. The hook-out pin also engages in the hook-out slot. A guide slot is provided on the guide rail and a guide pin is provided on the cover support, the guide pin gliding in the guide slot.Type: GrantFiled: August 26, 2002Date of Patent: December 30, 2003Assignee: ArvinMeritor GmbHInventors: Michael Eiermann, Klaus-Peter Hoffmann

Patent number: 6033119Abstract: A running wheel block, including a housing having at least one connecting surface for connection to a supporting structure, an inwardly directed rotary bearing holding hub arranged in the housing, a rotary bearing mounted on the hub, and a running wheel mounted in the rotary bearing so that a section of its running surface projects from the housing toward at least one side. The housing is open on a side opposite to the holding hub. The running wheel encompasses the holding hub and is insertable onto or into the rotary bearing from the open side.Type: GrantFiled: April 20, 1998Date of Patent: March 7, 2000Assignee: Mannesmann AGInventors: Eberhard Becker, Udo Gersemsky, Winfried Gievers, Klaus-Peter Hoffmann, Karl Liebig, Bernd Neupert, Hans-Hermann Osthoff, Thomas Schweflinghaus, Roland Staggl, Karl Zacharias

Patent number: 5992913Abstract: The invention is directed to a running wheel for traveling units which are movable on rails, especially for traveling cranes. The running wheel includes an outer running ring, a resilient damping hub inserted in central opening of the running ring. The hub transmits torque received from a drive shaft to the running ring. The resilient damping hub effectively intercepts occurring torque peaks forward of the gear unit and drive shaft, by elastically deforming while maintaining a connection at the central opening of the running ring without play.Type: GrantFiled: October 22, 1997Date of Patent: November 30, 1999Assignee: Mannesmann AktiengesellschaftInventors: Eberhard Becker, Andreas Duhme, Udo Gersemsky, Winfried Gievers, Ingo Grassmann, Frank Hildebrandt, Klaus-Peter Hoffmann, Gregor Jansen, Karl Knaack, Hans-Hermann Osthoff, Thomas Schweflinghaus, Roland Staggl, Manfred Stober

Patent number: 5943960Abstract: A running wheel block, including a housing having at least one connecting surface for connection to a supporting framework, and further having two opposing, detachable side walls, two inwardly directed rotary bearing holding hubs, arranged in the housing, rotary bearings mounted in the hubs, and a running wheel mounted in the rotary bearings so that a section of its running surface projects from the housing toward at least one side. Each of the holding hubs is arranged on one of the two opposing side walls of the housing. The housing further includes at least one spacing holder arranged between the opposing side walls. The spacing holder forms a connecting surface. The detachable side wall has centering members that, when the side wall is attached to the housing, determine the position of the holding hubs relative to the running wheel axis.Type: GrantFiled: April 20, 1998Date of Patent: August 31, 1999Assignee: Mannesmann AGInventors: Eberhard Becker, Udo Gersemsky, Winfried Gievers, Klaus-Peter Hoffmann, Karl Liebig, Bernd Neupert, Hans-Hermann Osthoff, Thomas Schweflinghaus, Roland Staggl, Karl Zacharias

Patent number: 5931584Abstract: A running wheel block, including a housing having at least one connecting surface for connection to a supporting structure, two inwardly directed rotary bearing holding hubs arranged in the housing, rotary bearings mounted on the hubs, a running wheel mounted in the rotary bearings so that a section of its running surface projects from the housing toward at least one side and a cover connected to the housing so as to close the housing. The holding hubs include a first holding hub that is arranged on the cover. The cover has centering members for fixing a position of the holding hub relative to an axis of the running wheel when the cover is closed.Type: GrantFiled: April 20, 1998Date of Patent: August 3, 1999Assignee: Mannesmann AGInventors: Eberhard Becker, Udo Gersemsky, Winfried Gievers, Klaus-Peter Hoffmann, Karl Liebig, Bernd Neupert, Hans-Hermann Osthoff, Thomas Schweflinghaus, Roland Staggl, Karl Zacharias
