The authors of the article describe after a brief theoretical introduction the automatic calibrating system developed for this purpose, and make known its application. Tibor Komáromi: Possibilities of controlling of the mechanical annealing The author makes a review of the measuring methods of remaining stresses cumulated in structural elements during forming and material processing. He makes known by practical example the blind-bore measuring method with strain gauges. Beside this, he introduces an acoustic emission method as the possibility for the control of annealing operations. Dr. András Illényi - Dr. Klára Vicsi - Péter Barczikai: Perfectioning of man-machine contact with speechanalysis during data processing in measuring techniques Investigations have clearly proved that in critical circumstances, e.g. in dangerous situations the most reliable medium for man-machine communication is speaking. The authors of this paper make briefly known those concrete results they have reached in the Acoustic Research Laboratory „Békésy György” in the field of speech identification and synthesis. Rudolf Radnai: Collecting and processing of measured data with personal computers The appearing of personal computers in data collecting systems resulted in a great decreasing of costs. By using the control units produced in big series the hardware cost decreased, and by application of software packets for personal computers the software costs decreased too. This has enabled to automatize data collecting on more and more new fields, primarily in industrial measuring techniques. In this paper we introduce hardware and software novelties from the field of measured data collection.
