Title: Method for suppressing the influence of periodically occurring eccentricities of operating and/or supporting rolls
Inventor: UETZ GUENTER
IPC: B21B37/66
Filed: 1987-10-30
Abstract: The invention relates to a method for suppressing the influence of periodically occurring eccentricities of operating and/or supporting rolls in the rolling force measuring signal of the thickness control when rolling during the bullhead pass. The invention consists in that the circumference of the supporting roll is subdivided into equal sections by equidistant support points (K), the number of support points (K) being dependent on the maximum circumferential speed <IMAGE> and the minimum possible scanning time (tA), in that, during one revolution of the support rolls, each measuring signal picked up at the support points (K) is divided by a computer into a process-describing part <IMAGE>  and into an eccentricity-describing part <IMAGE> and is determined by means of a regression analysis, and in that these measuring signals thus obtained are used as a reference value for the thickness control until the operating and supporting rolls have been readjusted. <IMAGE>

Title: Method for controlling the opening of electric fuel injection valves of an internal combustion engine
Inventor: DENNE ALBERT DIPL ING
IPC: F02D41/34
Filed: 1987-12-16
Abstract: A method for supplying fuel to an internal combustion engine is already known in which the actual value of the fuel system pressure, applied to an injection valve, is compared with a set value and as a function of this the supply voltage of an electric fuel pump is varied so that the respectively fed amount of fuel is matched to the useful amount consumed. However, in order to obtain a further improvement in the noise behaviour and a lower power drain of the fuel pump, the invention provides for a calculated opening time which is transmitted to the injection valve to be compared with a specified set opening time and for the result of the comparison to be used to form actuation signals for the fuel pump so that the actual value of the valve opening time is approximated to the set opening time. The method is suitable for internal combustion engines used in motor vehicles. <IMAGE>

Abstract: The hitherto known picking attachments for harvesters consist of a one-part rotor with drawing-in blades arranged fixedly on it. In the event of wear of the drawing-in blades, the entire rotor has to be exchanged. To reduce the maintenance outlay, it is proposed to arrange on the blades (3, 4, 5, 6) of the drawing-in rotor (2) wearing strips (10, 11, 12, 14) which can easily be exchanged, so that the entire drawing- in rotor (2) does not have to be replaced in the event of wear of the drawing-in elements. It is proposed, furthermore, that it be possible for the comminuting knives (8) also to be brought into a position out of engagement with the slits of the blades (3, 4, 5, 6), and finally that there be additional cutting knives (29) in order to ensure that the stalks are pulled through and comminuted, without a compression of the stalks being necessary. <IMAGE>
