Title: Process for adjusting the operating position of blow-in lances relative to a molten bath and apparatus for carrying out the process
Inventor: HENSING PETER ING GRAD
IPC: C21C5/30
Filed: 1981-02-04
Abstract: Particularly in the production of steel, substances must be introduced into the molten bath by means of blow-in lances during the reaction process. Adequate immersion of the blow-in lances which burn away is ensured by a suitable advancing movement. The functional safety of such processes and apparatuses can be improved at an acceptable cost by adjusting the operating position of each blow-in lance by means of a current control loop. The instantaneous operating position of the blow-in lance is determined by means of a measuring process which serves to initiate a control operation for advancing the blow-in lance. The apparatus according to the invention has a measuring circuit (17) which is equipped with a measuring resistance (13) and to which the blow-in lance (6) and the molten bath (4) belong. At least one measuring current controller (19) whose control line (19') is connected to the advancing unit (7, 8, 9) for the blow-in lance (6) is coordinated with the measuring resistance (13). A continuous advancing movement is achievable by means of a down-circuit speed controller (22) and, if required, a motor current controller (23) for the adjusting motor (10) of the advancing unit (7, 8, 9). <IMAGE>

Title: Prediction arrangement for documents having mixed information content
Inventor: LIAO HENRY H
IPC: H04N1/417
Filed: 1981-06-16
Abstract: A prediction bit pattern consisting of selected bits of the instantaneous and preceding raster scanning lines and a method for predicting a number of bits per clock pulse are described. In general, a prediction device is used before data decoding in order to increase the compression. The instantaneous bit in a bit sequence is compared with the predicted value and a one is output when the two values are not equal. An effective prediction device reduces the number of ones in a bit sequence which increases the number of zero-chain lengths which increases the performance of a run-length coding system. The bit pattern described contains bits which are close to the instantaneous bit in order to effectively predict half-tone data and neglects a number of intermediate bits in order to reduce the hardware costs. A two-stage method is also described which provides for the parallel prediction of a number of bits. A circuit for carrying out this method comprises a buffer (15) for storing the data of the preceding line and of the current line, two registers (LR1, LR2, LR3, LR4, R0, R1 and R2) for holding or storing the prediction data patterns for the preceding and instantaneous line and two PROMs (16, 17) for carrying out the two-stage prediction. <IMAGE>
