Patent number: 6655903Abstract: The invention considerably reduces the danger of deformation for containers made from a thermoplastic material during the transfer to a stacking magazine or into a locally fixed catch plate. This deformation danger results from the fact that the formed stack must be displaced within a short time by the stack distance, either through the transferred containers themselves or by components of a catch plate that is moved forward with each cycle. This is achieved through displacing the stacks in the stacking magazines or the locally fixed catch plate with a displacement device. The displacement device can be combined with the stack removal device or can be a separate displacement device. According to a modification of the invention, the method is intended to improve the cooling of the stacked containers.Type: GrantFiled: September 7, 2001Date of Patent: December 2, 2003Assignee: Adolf Illig Maschinenbau GmbH & Co.Inventor: Hans Köhler

Patent number: 6318496Abstract: A steering booster system for a motor vehicle has an electronic control unit which senses by way of force or torque sensors the amount and direction of forces and torques applied to a manual steering wheel and correspondingly controls, via a transmission arrangement, the steering-force-assisting connection of an electric motor into a steering gear line coupling the manual steering wheel and the steered vehicle wheels. The manufacture of the system is simplified and the controllability of the force transmission between the electric motor and the steering gear line is improved by providing that the transmission arrangement has an electrically switchable clutch for each steering direction, i.e., left or right. The two clutches are arranged such that, when the rotating direction is the same at the input of the transmission arrangement assigned to the electric motor, they in each case cause another rotating direction at the output of the transmission arrangement assigned to the steering gear line.Type: GrantFiled: October 5, 1998Date of Patent: November 20, 2001Assignee: Mercedes-Benz Lenkungen GmbHInventors: Karl-Hans Koehler, Michael Peetz, Albrecht Pluschke, Gerd Speidel

Patent number: 6227244Abstract: A reaction arrangement on a hydraulic servo-valve arrangement which is designed in the manner of a rotary-slide arrangement, with a rotary slide and with a control bush coaxially surrounding the rotary slide and rotatable relative to the latter, in particular for power steering systems of motor vehicles. Arranged on a shaft part located on the rotary-slide side are axial V-grooves, into which reaction bodies can be pressed with controllable hydraulic pressure. The reaction bodies are guided radially on a bush portion connected fixedly in terms of rotation to the control bush.Type: GrantFiled: June 4, 1999Date of Patent: May 8, 2001Assignee: Mercedes-Benz Lenkungen GmbHInventors: Bernd Schick, Bernd Langkamp, Edwin Breuning, Karl-Hans Koehler

Patent number: 5711396Abstract: A rack-and-pinion steering or control system with a servomotor, especially an electric motor, which can be coupled to the rack by way of a mechanical transmission and runs continuously in one direction is provided. The rack is designed over a certain area as a screw which interacts with a recirculating ball sleeve which can be driven in two directions of rotation by the motor. To control the direction of rotation, use is made of normally disengaged clutches which can be controlled as a function of a small displacement of the recirculating ball sleeve.Type: GrantFiled: October 31, 1995Date of Patent: January 27, 1998Assignee: Mercedes-Benz AGInventors: Wolfgang Joerg, Jaromir Bordovsky, Aydogan Cakmaz, Hubert Heck, Arno Roehringer, Claus Gall, Reinhold Abt, Rainer Strauss, Karl-Hans Koehler

Patent number: 5671637Abstract: A servo-assisted rack-and-pinion steering system in which the rack is drive-coupled to a pinion which is mounted to move between two end positions in the longitudinal direction of the rack so that its movements control the servo motor. The end positions of the pinion are defined by two friction wheels which are driven continuously in opposite directions by the servo motor, in each case allowing an auxiliary force to be transmitted to the pinion.Type: GrantFiled: November 30, 1995Date of Patent: September 30, 1997Assignee: Mercedes-Benz AGInventors: Wolfgang Joerg, Jaromir Bordovsky, Aydogan Cakmaz, Hubert Heck, Arno Roehringer, Claus Gall, Reinhold Abt, Rainer Strauss, Karl-Hans Koehler

Patent number: 5655620Abstract: A servo-assisted rack-and-pinion steering system is provided in which the rack cooperates with a rotatable pinion. The pinion is supported in an eccentrically located opening in a circular disk rotatably mounted by rolling elements on its periphery. Pivoting movement of the pinion controls an hydraulic oil actuated servo motor. The rolling contact bearing of the disk lies in the path of flow of the hydraulic oil for the servo motor. The pinion is supported in a bearing in the opening in the disk and another bearing at an opposite side of the rack and separate from the disk.Type: GrantFiled: June 28, 1995Date of Patent: August 12, 1997Assignee: Mercedes-Benz AGInventors: Wolfgang Joerg, Jaromir Bordovsky, Aydogan Cakmaz, Hubert Heck, Arno Roehringer, Claus Gall, Reinhold Abt, Rainer Strauss, Karl-Hans Koehler
