Abstract: A device for reproducing digitally presented video pictures includes a restoration circuit for restoring erroneous picture elements. To this end a reference sub-picture is composed of erroneous and correct picture elements, the erroneous picture elements being entirely enclosed by the correct picture elements. Before restoring the erroneous picture elements, a correction function is determined, starting from the correct picture elements of the reference sub-picture, and by means of this corection function a correction value can be determined for each correct picture element in the reference sub-picture such that the difference picture elements obtained by subtracting tne associated correction value from each correct picture element represent a signal whose mean value is zero. A known method of restoring erroneous picture elements can now be used for these difference picture elements.

Abstract: The invention relates to a process for the treatment of dried aspartame characterised in that, in a first separation step, particles smaller than 50  mu m are removed, with the aid of a stream of air, from aspartame having a particle size distribution with which more than 5 wt.% of the aspartame has a particle size of less than 20 mu m and more than 10 wt.% of the aspartame has a particle size of more than 400  mu m, and that in a second separation step the product resulting from the first step is subjected to a screening step using a screen that separates at a value between 150 and 250  mu m, after which the fraction of the smaller particles thus obtained is recovered as a first product and the fraction of the larger particles is recovered as a second product or is optionally subjected to a further separation step using a screen that separates at a value between 400 and 1000  mu m, the fraction of smaller particles thus obtained being recovered as the second product. Aspartame having a particle size distribution with which 97% of the particles is larger than 20  mu m and 97% of the particles is smaller than 250  mu m appears to present exceptionally good properties as regards processability and dissolution rate.

Patent NL-9300543-A (NL)
Title: System for cleaning root crops
IPC: A01D19/16
Filed: 1993-03-25
Abstract: The invention relates to a harvesting machine for tuberous plants. When harvesting beet, the beet has to be intensively cleaned. The beet are transported to horizontally positioned stars and are thrown towards the outer circumference of these stars by the centrifugal forces. These stars resemble wheels with spokes. A cleaning rack is placed on the outer circumference and also prevents the beet from being thrown out. The object of the invention is to incorporate additional cleaning in the machine by providing at least two stars with the same direction of rotation. The beet leave the star and are thrown a short way onto the next star. Since the star beneath it continues to rotate, in the opposite direction to the direction of movement of the beet, additional cleaning results. This method of cleaning has the possible drawback of excessively impeding the flow of beet due to the loss in speed of the beet. To prevent this, and to increase the cleaning action, a rotating roller is mounted transversely to the ejector from the star and in line with the direction of movement of the flow of beet. This roller has two purposes: - The beet are cleaned both on the underside by the star and on the side by the roller. - The flow of beet is deflected in the direction of the direction of rotation of the star onto which they are to be conveyed at that moment.

Title: A method for producing selenium salts
IPC: C01B19/00
Filed: 1983-12-14
Abstract: The present invention relates to a method for producing alkalimetal selenite and alkalimetal selenate from metallic selenium through selenous acid. The selenium is dissolved in nitric acid to form selenous acid, which is reacted with an alkalimetal base, to form alkalimetal selenite. The formed selenite is then spray dried. Alternatively, the formed selenite is oxidized at elevated temperature in a basic environment at pH 10-12, with hydrogen peroxide as the oxidant, to form selenate, which is then spray dried.The invention also relates to products produced by the method. The products are intended to be incorporated in animal-fodder or foodstuffs (selenite), or in fertilizers (selenate), to be thus administered to human beings and animals as trace substances.

Title: Capacitive position tranducer
Inventor: KUNC VINKO
IPC: G01B7/00
Filed: 1998-04-08
Abstract: In the capacitive position transducer the induction electrodes (EEa, EEb...) of the position signal generator (PI) are induced by a combination of basic signals (U1, U2,...). On the output of means (SR1, SR2,...) for the decomposition on the opposite electrode (OE) of the electrically induced signal to basic signals and measuring of amplitudes of such basic signals, the position of the opposite electrode (OE) regarding the specified induction electrodes is determined. The induction electrodes (EEa, EEb,...) are made as an integral part of the integrated transducer signal processing circuit. By simultaneous providing of a combination of several basic signals to each induction electrode in the position transducer, its sensibility regarding the deviation from the required geometry is reduced thus allowing to provide a simple concept of capacitive position transducers.
Patent TR-21061-A (TR)
IPC: C21C7/068
Filed: 1981-01-13
Abstract: A process is disclosed for the decarburization of a molten bath of chromium-containing pig iron which, in a single operation, permits decarburization by means of an oxygen jet and thus permits chromium or nickel chromium steels to be obtained directly, the decarburization of which can readily be completed by a final treatment under vacuum carried out immediately after the injection of oxygen. The process comprises adjusting the temperature conditions of the pig iron bath and regulating the oxygen jet distance from the surface of the bath and speed of oxygen gas so that the impact force of the oxygen creates a gas-metal emulsion within which the carbon contained in the pig iron is oxidized directly by the oxygen. The carbon content is thus rapidly reduced to less than 0.3% whereas the yield of chromium is higher than 97%. The process is suitable for the preparation of all grades of Cr and NiCr stainless steel, which optionally contain additions of Co, Mn or Mo.
