Patent number: 9097438Abstract: The aim of the invention is to build central receiver solar power plants in which the heliostat fields can be used more efficiently. To achieve said aim, a heliostat field consisting of a near field having a uniform reflector surface density ? of more than 60% is preferably combined with a far field whose reflector surface density ? decreases as the distance from the receiver increases. The invention also comprises central receiver solar power plants which consist exclusively of a near field having a uniform reflector surface density ? of more than 60%. The high reflector surface density ? in the near field and in areas of the far field is achieved by the use of heliostats having rectangular reflectors and a rigid horizontal axle suspension (FHA) or, alternatively, by heliostats having rectangular reflectors and a rigid quasipolar axle suspension (FQA).Type: GrantFiled: July 22, 2011Date of Patent: August 4, 2015Inventors: Philipp Schramek, Joachim Maass

Patent number: 7559595Abstract: A convertible device of a vehicle comprises a convertible top (10) movable between a closed position and a folded-together, lowered open position and a separating wall (22, 24) separating the convertible top at least in its folded-together open position at least partially from the interior of a luggage space (19) of the vehicle when the convertible device is mounted thereon. At least a portion of the separating wall is formed by a rear shelf part (24) that separates the passenger compartment from the luggage space in the closed position of the convertible top and during movement of the folding top into its open position moves downwardly together with the lower, rear edge portion of the convertible top, so that the folded-together convertible top is disposed above the rear shelf part. A sensor apparatus detects an object located in the luggage space and hindering a lowering of the rear shelf part.Type: GrantFiled: April 27, 2005Date of Patent: July 14, 2009Assignee: Wilhelm Karmann GmbHInventors: Winfried Bunsmann, Joachim Maass, Heiko Schonhorst

Patent number: 6431637Abstract: Convertible vehicle with a roof which can be folded up and is provided with a rear window and two lateral clamping collars at the rear. The rear window is movably in a guideway defined by a roof frame part on the roof and a car body frame part on the car body. In a closed position of the roof, the rear window is movable from a closed normal position into a lowered position. The roof is constructed so that the clamping collars are connected firmly with one another over a transverse connecting part and, between the roof frame part and the car body frame part, a space is provided in the guideway for the passage of the transverse connecting part during the folding up of the roof.Type: GrantFiled: December 20, 2000Date of Patent: August 13, 2002Assignee: Wilhelm Karmann GmbHInventor: Joachim Maass

Patent number: 6322131Abstract: The invention relates to a convertible vehicle with a roof, which can be folded up and is provided with a rear window, it being possible, in the closed position of the roof, to lower the rear window at least regionally from a normal position into a lowered position below a window parapet line forming the upper boundary of the car body. In order to simplify the installation of a movable rear window for such an embodiment, provisions are made so that the rear window, in the lowered position as well as in the normal position, is held in a frame, which is firmly connected with the roof, as a result of which special adjustment of the rear window or of a different component with respect to the roof is superfluous.Type: GrantFiled: March 20, 2000Date of Patent: November 27, 2001Assignee: Wilhelm Karmann GmbHInventors: Joachim Maass, Frank Lehnig

Patent number: 6302470Abstract: A convertible vehicle with a roof, which can be folded up, is provided with a rear window, can be stowed in a rear region of the vehicle and is braced over at least one tension bracket in the closed state with respect to the car body, the tension bracket being pivotable in the forwards direction for opening the roof and hereby bringing about a forward displacement of the rear window. In the case of such a construction, in order to be able to carry out the forward shifting of the rear region of the folding top, comprising the rear window, without being obstructed by upright parts, such as the rear head supports or roll bars, provisions are made so that the rear window is held in a frame which, on the folding top side, is opened downward and, during the opening and closing of the roof, can be swiveled up with respect to this frame.Type: GrantFiled: March 20, 2000Date of Patent: October 16, 2001Assignee: Wilhelm Karmann GmbHInventors: Joachim Maass, Frank Lehnig

Patent number: 5816644Abstract: A foldable top for a convertible includes a vehicle body, a windshield frame on the vehicle body, a rear region on the vehicle body disposed rearwardly of the windshield frame, a foldable-rod linkage supportable on the windshield frame, a main power operated device mounted on the vehicle body for moving the foldable-rod linkage between closed and open positions, and a rear roof clamping member at the rear region of the vehicle body. Rail members are pivotably connected to each other and are also pivotably connected to the foldable-rod linkage and to the clamping member. A tensioning linkage is pivotably connected to one of the rail members and pivotably connected to the vehicle body. A drive mechanism mounted on the vehicle body is pivotably connected to the tensioning linkage and is operable to pivot the tensioning linkage which in turn pivots the rail members.Type: GrantFiled: June 20, 1996Date of Patent: October 6, 1998Assignee: Wilhelm Karmann GmbHInventors: Karl Rothe, Joachim Maass
