Publication number: 20130236615Abstract: A method for providing cooking programs for at least one selectable product to be cooked, which can be cooked in at least two different charges in a cooking chamber of a cooking appliance. Cooking processes conducted depending on charge-dependent parameters are replaced by cooking programs that depend solely on fixed parameters. One cooking program is assigned to each charge respectively. A cooking process is conducted as a function of at least one charge-dependent parameter at least once for each charge, with a caliber-dependent parameter determined by a core temperature of the product to be cooked being selected as the charge-dependent parameter. A cooking process that leads to a specific cooking result is selected for each charge, with the cooking result being determined by the core temperature of the product and a cooking program being stored for each selected cooking process after the charge-dependent parameter is replaced by a fixed parameter.Type: ApplicationFiled: August 12, 2011Publication date: September 12, 2013Applicant: RATIONAL AGInventors: Peter Wiedemann, Torsten Brinkmann, Katrin Lauterbach, Anja Machowetz, Jürgen Klasmeier

Patent number: 8269151Abstract: The invention relates to a method for displaying the curve when a desired climate has been reached in a cooking compartment of a cooking appliance by taking into account at least one actual value of the first variable that changes over time and is characteristic of the climate in the cooking compartment. Said method is characterized in that the actual value of the first variable is detected at least once during an interval t0 to t1 and is compared with a desired value of the first variable, said desired value characterizing the desired climate, a point in time t2 when a second interval is to begin and/or the point in time t3 when the desired climate has been reached is/are estimated in accordance with said comparison, and the course of the first variable over time is taken into account at least once when estimating the point in time t3 during a second interval t2 to t3, wherein t2?t1. The invention also relates to a cooking appliance for carrying out such a method.Type: GrantFiled: December 6, 2007Date of Patent: September 18, 2012Assignee: Rational AGInventors: Juergen Klasmeier, Michael Greiner, Peter Wiedemann, Manfred Breunig, Bruno Maas, Michael Fink, Judith Kling, Cornelia Dietmayer

Patent number: 8261650Abstract: The invention concerns a cocking device for a bolt mechanism with a cocking slider (13, 14), which can be displaced, on a breech housing (2), between a rear uncocking position and a front cocking position, for the cocking and uncocking of a striker spring and a catch (21), located on the cocking slider (13, 14), which works together with a mating catch (23) to hold the cocking slider (13, 14) in the front cocking position. In order to attain an improved safety with respect to an unintended release of a shot, an uncocking mechanism (25, 29) for the automatic uncocking of the striker spring (48), when the magazine (5) has been removed, is correlated with the cocking slider (13, 14).Type: GrantFiled: December 6, 2010Date of Patent: September 11, 2012Assignee: Blaser Finanzholding GmbHInventors: Oliver Hagspiel, Peter Wiedemann

Patent number: 8025740Abstract: A process for conducting cleaning operations at predetermined time intervals in a chamber or container of a fluid-receiving device of a foodstuff-processing apparatus first comprises receiving a first fluid in the chamber or container. Then, first and second degrees of cleaning are determined at first and second moments in time, respectively. Then, a first difference between the first and second degrees of cleaning is determined. In a first case, in which the second degree of cleaning lies below a first limit value, the action duration of the at least one cleaning agent during at least one subsequent cleaning operation is set depending on the first degree of cleaning. In a second case, in which the second degree of cleaning lies above the first limit value, a greater amount of cleaning agent is supplied and/or the time interval between two subsequent, successive cleaning operations is shortened.Type: GrantFiled: January 30, 2007Date of Patent: September 27, 2011Assignee: Rational AGInventors: Andrea Juergens, Gerhard Kramer, Judith Kling, Tobias Gayer, Wolfgang Holzapfel, Bruno Maas, Erwin Schuller, Kerstin Geiger, Peter Wiedemann, Manfred Breunig
