Title: Measuring liquid level in opaque containers - by accelerating and/or decelerating container and measuring forces on walls
Inventor: TILL HEINZ
IPC: G01F23/22
Filed: 1980-03-04
Abstract: A method and arrangement for measurement of level in opaque liq. containers are applicable to cylindrical kegs. They overcome the problems associated with X-ray and ultrasonic measurement of possible contamination, cost, inaccuracy, and inefficiency. The container (1) is accelerated and/or decelerated so that the liq. is subjected to motion relative to the container. The resulting forces transferred to the walls of the container are measured and used to determine the level of liq. The acceleration and/or deceleration may be set up so as to induce an oscillatory liq. motion relative to the walls of the container. This can be achieved by tipping or rotating the container about horizontal, vertical, or other axes which would pref. be asymmetrical.

Title: Capacitive checking and evaluating device on bookbinding and printing machines
Inventor: BEYER WOLFGANG DIPL-ING
IPC: B65H7/12
Filed: 1981-01-02
Abstract: The invention relates to a capacitive checking and evaluating device for checking incorrect and/or multiple sheets in bookbinding and printing machines. The aim of the invention is to increase the accuracy of checking and evaluating devices of this type. The object of the invention is to provide a capacitor arrangement, together with an evaluation circuit assigned to it, which compensate influences on the measured values caused by oscillations of the capacitor plates and distortions of the sheets and which thus prevent the possibility of false checking results. The technical object is achieved in that one capacitor plate of the measured-value transmitter is separated at two points and is located on a basic body, and in that the two capacitor plates are mounted elastically in the machine, and the sheet material to be checked is located between the middle part of the separated capacitor plate and the second capacitor plate and this capacitive arrangement is arranged in a measuring-bridge circuit. The subsequent evaluation circuit evaluates the output signal from the measuring-bridge circuit in terms of normal, incorrect and multiple sheets. <IMAGE>

Title: Process for producing gypsum hemihydrate using waste heat
Inventor: QUANTE HEINRICH
IPC: C04B11/02
Filed: 1981-02-17
Abstract: For calcining the flue gas gypsum produced during flue gas desulphurisation, in particular in coal-fired power stations, heat is required. The required heat is used in the form of industrial, dust-free waste heat, in particular water vapour or hot air, the relatively low temperatures of the waste heat being usable for calcining in that the calcium sulphate dihydrate starting product is intensively mixed with aqueous sulphuric acid and then heated with the aid of the waste heat with a predetermined heating rate. After a temperature of 90-100 DEG C is reached, the gypsum hemihydrate then formed is separated from the aqueous sulphuric acid and subsequently dried at 105-130 DEG C. To obtain an approximately continuously running process, a plant comprising three converters and, if appropriate, three concentrators is provided, in which plant both the mixing operation and the calcining operation, and also the separation operation, take place by steps. <IMAGE>
