Patent number: 7416240Abstract: The invention relates to a cabriolet vehicle (1) with a roof (2; 102), comprising at least two moving units (6, 14; 106, 114) each mounted on main bearings (7, 8; 15, 16; 107, 108; 115) fixed to the chassis such as to move and each of which is provided with a rigid roof section (3, 4; 103, 104). At least one rear rigid roof section (4; 104), comprising a rear window (5; 105), is connected to a main bearing (15, 16; 115) by means of a multi-part articulated chain (17; 117), whereby a part (18; 118) of the articulated chain (17; 117) brings about at least one movement of the rigid roof section (4; 104) relative to the main bearing (15, 16; 115) and a part (19; 119) of the articulated chain (17; 117) brings about at least one change in the angular position of the rigid roof section (4; 104).Type: GrantFiled: December 19, 2003Date of Patent: August 26, 2008Inventors: Stefan Eichholz, Jurgen Theuerkauf

Patent number: 6832804Abstract: A convertible vehicle has a carbody having a rear area and a roof stowable in the rear area of the carbody. The roof has a rigid rear roof end member and a rear window. A passageway allows movement of the roof relative to the carbody. The passageway, when the roof is in a closed position, is located in front of the rear roof end member and below the rear window. A movable cover functioning as a rear deck closes the passageway at least partially. The movable cover is connected to the roof in an area of the rear roof end member and is movable together with the roof.Type: GrantFiled: April 23, 2003Date of Patent: December 21, 2004Assignee: Wilhelm Karmann GmbHInventors: Stefan Eichholz, Frank Neubrand

Patent number: 6702362Abstract: A convertible vehicle has a carbody having a rear area and a roof connected to the carbody. The roof has a first rigid roof part arranged rearwardly and provided with a rear window. The roof further has at least one second rigid roof part. The first and second roof parts can be nested into one another when opening the roof and stowed in the stowed position in the rear area of the carbody. The first roof part is positioned in a stowed position of the roof above the at least one second roof part in a substantially horizontal position. The rear window has an exterior side in a closed position of the roof, and the exterior side of the rear window in the stowed position faces upwardly.Type: GrantFiled: April 23, 2003Date of Patent: March 9, 2004Assignee: Wilhelm Karmann GmbHInventors: Stefan Eichholz, Thorsten Budzinski

Patent number: 5628203Abstract: The invention is directed to a system and process operating on an air-standard cycle either to cool or heat a room. The system may be advantageously employed to cool or heat relatively small areas or rooms, particularly driver's cabins in locomotives and the like. In cooling operation, outside air is expanded in a turbine, cooled below ambient, and introducted into a heat exchanger. Air from the room to be cooled is introduced into the heat exchanger and heat is removed therefrom. Suitable valves are provided to change the operation of the heat exchanger to that of a regenerator and to direct the flow of air accordingly. Specifically, air heated by compression in the compressor is directly introduced into the room and air leaving the room is passed through the regenerator/heat exchanger and released into the atmosphere.Type: GrantFiled: March 18, 1994Date of Patent: May 13, 1997Assignees: Hagenuk Fahrzeugklima GmbH, Normalair Garrett Ltd.Inventors: Ulrich Adolph, Stefan Eichholz, George R.

Patent number: 4987346Abstract: The invention relates to a particle source with which positive, negative, and neutral particles can be generated and applied on a substrate. The particle source comprises a container (26) in which a gas or gas mixture to be ionized is held. Into this container (26) an electromagnetic wave irradiates which preferably is a microwave. A torus-shaped magnetic field, which is generated with the aid of permanent magnets (32, 33) or electromagnets, simultaneously projects into the container (26). With the aid of a special control grid configuration (38, 39, 40) it becomes possible to draw off positive, negative or neutral particles from the container (26).Type: GrantFiled: January 18, 1989Date of Patent: January 22, 1991Assignee: Leybold AGInventors: Werner Katzschner, Stefan Eichholz, Michael Geisler, Michael Jung
