Publication number: 20090152457Abstract: Described is a method for analysis of a solid sample and, in particular, for analysis of the material composition and distribution in or on a solid surface. The surface to be analysed is covered with caesium, at least partially and/or in regions, and the surface is irradiated with an analysis beam which contains predominantly or exclusively polyatomic ions with at least 3 atoms per ion. The secondary ions which are produced are then analysed on caesium compound.Type: ApplicationFiled: May 19, 2006Publication date: June 18, 2009Inventors: Ewald Niehuis, Reinhard Kersting, Rudolf Möllers, Thomas Grehl

Patent number: 7174606Abstract: A pressure cylinder including a cylinder housing having one end including an opening. A piston is axially displaceable within the cylinder housing. A piston rod is coupled to the piston and extends through the opening at the one end of the cylinder. A cylinder base closes off the cylinder at an end of the cylinder housing opposite the opening. The cylinder also includes a pressure chamber between the piston and the cylinder base and capable of being pressurized by a pressure medium and a switching disk for interacting with a switch to determine the position of the piston. The switching disk is displaceably positioned in the pressure chamber in frictional engagement and coaxially with the piston rod so that the switching disk passes to a starting position near the piston in response to a pressure impulse overcoming the frictional engagement when the pressure chamber is first pressurized.Type: GrantFiled: November 26, 2003Date of Patent: February 13, 2007Assignee: Rexroth Mecman GmbHInventors: Rudolf Möller, Dirk Kröger, Salih Agca, Christoph Leinders

Patent number: 6186180Abstract: A plug-in connector, especially for hose connections and for use in motor vehicles, including a receptacle and a plug. The receptacle may be provided with an insertion opening for receiving the plug and a groove for retaining at least one locking spring which may be used to lock the receptacle and plug together. The locking spring may include at least one locking section and one unlocking section which can be actuated from the outside of the receptacle.

Connection element for providing an electrical connection to electrical elements arranged in a group
Patent number: 6042425Abstract: A relatively simple assembly and an economical manufacture for the electrical connection of electrical elements arranged in a group, especially electromagnets of valve units, using a multiple-pin electrical bridge connection in which the electrical connection proceeds from contacts of a plug on the input side to contacts of a socket on the output side. The socket is constructed so as to complement the plug. A two-pin or two-pole connection is preferably disposed on the external surface of the electrical bridge connection for connecting electrical elements. All of the electrical connections in the connection element extend three-dimensionally in the form of conductor paths. The connection element (1) is constructed in one piece comprising a plug (2) that forms a first portion, a socket (3) that forms a second portion and a base (4) disposed between the first and second portions and through which the conductor paths are guided.Type: GrantFiled: April 22, 1998Date of Patent: March 28, 2000Assignee: Mannesmann AktiengesellschaftInventors: Rudolf Moller, Dirk Uhlmannsiek -
Patent number: 6003835Abstract: A diaphragm valve includes a diaphragm with a rigid insert. The diaphragm is arranged over a valve seat.

Patent number: 5819788Abstract: A base-plate distributing valve comprised of a valve body, a base-plate element and a valve element slidably disposed within a longitudinal bore of the valve body. Pressure medium line ports and pressure medium lines are contained within the valve body and the base-plate element. The base-plate element contains an opening into which the part of the valve body which contains the valve element may be inserted. Within the valve element are valves. A drive element controls the valve element which shifts position the position of the valves within the longitudinal bore of the valve body to permit alignment of the pressure medium lines for flow therethrough. Accordingly, when the valve body is inserted into the base-plate element in a pressure-medium-tight seal, a substantially straight-lined flow of a medium through the base-plate element at a high flow rate is achieved.Type: GrantFiled: October 11, 1996Date of Patent: October 13, 1998Assignee: Mannesmann AktiengesellschaftInventors: Thomas Liesenhoff, Jens-Olaf Hartig, Raimund Buschmann, Diane Gottling, Helmut Gottling, Rudolf Moller, Peter Muller, Gerhard Scharnowski

Patent number: 5596790Abstract: The invention relates to a hose clamp (1) with a clamp body (3) which encloses a hose end (2) essentially in a ring with overlapping end areas (4,5). In the clamped state, the clamp body has an initial diameter, and using a clamping tool, the clamp body (3) can be spread to a second, larger diameter against its own spring force. In a first end area (4), there is a catch projection (6) which is offset rearward relative to its outer front edge (7) and which can be engaged with a second end area (5) of the clamp body (3) to achieve the spread state. The second end area (5) has a longitudinally extended recess (8) which holds first end area (4) which is correspondingly narrower.
