Patent DE-2407430-A1 (DE)
Title: Rolled strip thickness measurement - by calculation from force, screwdown position and stand elasticity plus correction
Inventor: HERTLEIN KURT DIPL ING
IPC: B21B37/66
Filed: 1974-02-13
Abstract: The thickness or the thickness error of metal strip leaving a rolling mill stand is determined for a thickness control system by calculating it from the measured roll force, the screwdown position and the stand spring constant (restoring force). This is passed to a delay unit which is controlled by the roll speed to make the signal input-output delay in the unit equal to one roll revolution. The input-output difference and the arithmetic mean of the input signal are calculated, and the two are added to arrive at the true thickness (or thickness error). This removes the periodical fluctuations in the roll force signal, caused by the out-of-roundness of the rolls. This eliminates wrong control commands from the thickness control to the screwdown drive.

Title: Electro-pneumatic control for train brakes - has bridge network to compare signals and differential amplifier to reduce hysteresis
Inventor: HUBER JOHANN
IPC: B60T8/17
Filed: 1975-02-27
Abstract: The pneumatic brake pressure of the train brakes are monitored by a set of sensors whose output signal is applied to one arm of a Wheatstone bridge network, with another arm supplied with the command signal from the brake control lever. THe output from the bridge is passed to a differential amplifier where it is compared with correction signals, to generate the accurate correction signals to regulate the brake pressure. The system eliminates the hysteresis associated with relay-operated brake controls, as well as the instability of purely differential amplifier control, which can lead to large deviations from the control signals. The resulting brake control has smooth and fast response.
Patent DE-2512518-A1 (DE)
Title: Working up the aqs residues from accumulator prodn. - to obtain recyclable streams free of gypsum
Inventor: SALZER RICHARD
IPC: C02F11/122
Filed: 1975-03-21
Abstract: In a process for working up Pb-contg. washings from accumulator plate mfg. so as to obtain Pb-rich sludges, the PbO-laden wash water from the smearing stage is treated with org. flocculants so as to remove the PbO which latter is then rendered pumpable by stirring and the clarified water recycled to the plate smearing stage. The PbO sludge is dewatered in filter presses and the water obtd. added to that recycled to the plate smearing stage. The washings and cooling water obtd. from the forming and drying stages, which have low Pb contents and contain H2SO4, are adjusted to pH 8-9 with Ca(OH)2 and aerated to form sparingly sol. pB cpds. Org. flocculants are then added, the solids removed and the clarified water recycled, after addn. of some fresh water, to the accumulator finishing stages while the solids are dewatered in filter presses to low-Pb gypsum sludge and the water obtd. added to that of the washing/cooling stages of the forming/drying processes. The semi-concentrate, comprising H2SO4, PbO and PbSO4, from the forming stage is freed of Pb sludge and the latter rendered pumpable by stirring while the clarified sludge is added to that of washings and cooling water obtd. from the forming/drying stages. The Pb sludge is washed and the washings also added to the washings/cooling water from the forming/drying stages which the Pb sludge is neutralised with NAOH and added to the washings from the smearing stage and treated therewith. Using NaO and Ca(OH)2 as neutralising agent and pptg. agent, a simple and cheap method is afforded to re-use water without fear of contamination with gypsum (or to re-sell it) and to obtain a low-Pb gyppsum sludge.
