Abstract: The invention relates to a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs. In order to specify a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs, it is proposed that the temperature of the cooling fluid at the coolant outlet of each of the liquid-cooled plates of a mould should first of all be measured, that a cooling surface-related specific temperature value be formed from the measured temperature, that the specific temperature values of opposite plates be compared, furthermore that a comparison of the temperature values of each plate with the specific temperature values of the adjoining plates be carried out and that, if there is a difference between the temperature values, an actuating value corresponding to the size of the difference be applied to the drive of that narrow face which delivers the lower temperature value to bring about an increase in the taper.

Abstract: An NTSC compatible television system capable of enhanced resolution images with an appropriate receiver is described. The video transmission associated with this system may be received by a standard NTSC television receiver and displayed in letter-box format. The added information required to achieve enhanced resolution in an 16 by 9 format is bit reduced and transmitted either during the mask areas present when viewing the signal on an NTSC standard receiver and/or in a quadrature channel typically not detectable without a special decoder by the NTSC receiver. The digital information transmitted during the mask areas, the NTSC image, and the digital information transmitted via the quadrature channel are combined to arrive at the enhanced resolution television display.

Abstract: An elevator car speed governor is mounted on the top of the car assembly (2), and measures car speed by contacting a fixed element (6) in the hoistway. The fixed element can be a taut cable extending from the top of the hoistway to the pit, or one of the car guide rails, for example. The governor has a centrifugally operated connection (16,18) with emergency brakes (22) on the car. When overspeed is detected, the connection is actuated to cause the brakes to engage the guide rails and stop the car. The governor can operate at relatively low overspeed rates, and can be used on elevator systems which do not have an overhead machine room, such as hydraulic and linear induction motor elevators.

Abstract: A method and system for the localization and characterization of the generators of human brain electromagnetic physiological activity includes a set bioelectromagnetic amplifiers (2), sensorial stimulators (4), and a computer based system (12) for signal analog to digital conversion and recording. Sufficient statistics (13), including higher order statistical moments, for event related components are computed from the recorded signals, either in the time, frequency, or time-frequency domain, retaining stationary, non-stationary, linear, and non-linear information. The localizations, orientations, activities, and connectivities of the generators are obtained by solving the inverse problem using sufficient statistics under anatomical and functional constraints. Realistic head geometry and conductivity profile are used to transform the measurements into infinite homogeneous medium measurements, by means of an anatomical deconvolution operator, thus simplifying optimally inverse solution computations. Goodness of fit tests (16) for the inverse solution are provided. Generator characteristics are visually displayed (18) in the form of three and two dimensional head images, and optionally include probability scaled images obtained by comparing estimated generator characteristics with those of a normal population sampled and stored in a normative data base.

Abstract: In an order sorting apparatus, particularly suitable for sorting records defining the positions and attributes of pixels of a digital video image, the values of the records are read into a first area (2C,2D) of a store (2). Records are sorted by reading key values of the records and storing in either one of two memory areas (2A,2B) linked lists of records of which a digit of a key field of the record of a given significance has the same value. The linked lists are formed by addressing one of two further memories (3) with the values of the relevant digit of the key field while reading the corresponding address of the memory (2) into the memory (3). At the same time, any previous data held at that address of the memory (3) is transferred to the relevant memory area (2A,2B). This operation is repeated for digits of ascending order of significance, data being written into alternate ones of the memories (2A,2B;3) in successive steps. In each step other than the first, the order in which records are read from the memory areas (2C,2D) is determined by the order in which pointers designating linked lists in the memory areas (2A,2B) are held in the memories (3) that had been written to in the preceding step.

Abstract: A method to convert gray level image data (V) from image input terminals, into binary data (O) for high-addressability image output terminals. High addressability output terminals such as printers (100) increase their virtual resolution in the fast scan direction in order to achieve a higher effective printing resolution. For example, one pixel (102) in the slow scan direction divided into eight pixels (106) in the fast scan direction, improves a printer's actual resolution from n spots x m spots per unit area to (8 * n) spots x m spots per unit area. Gray level input data representing pixel data from image input terminals such as scanners is encoded by either an analog signal or a quantized digital signal with a large number of levels (e.g. 256 levels). Binary output data has pixels with either a value of one or zero or a much smaller number of gray levels compared to digital input signals.

Abstract: Proposed is an improved radiation-curable organopolysiloxane composition capable of giving a cured surface film on a substrate surface which exhibits excellent releasability against sticky substances. The composition is obtained by combining two kinds of (meth)acryloxyalkyl-containing organopolysiloxanes in a specified weight proportion, of which one has a relatively large degree of polymerization but contains only a relatively small amount of the silicon-bonded (meth)acryloxyalkyl groups while the other has a relatively small degree of polymerization but contains a relatively large amount of the silicon-bonded (meth)acryloxyalkyl groups. By virtue of this unique formulation, the surface-release sheet provided with a cured surface film of this organopolysiloxane composition and attached to a sticky surface for temporary protection is safe from generation of a peeling noise which is unavoidable in the prior art when a surface-release sheet is peeled off from the sticky surface at a high peeling velocity, especially, when the peeling resistance is great.

Abstract: Processes are disclosed in which cemented carbide parts, having a wide range of initial carbon levels, and a wide range of sizes, can be carburized to a critical carbon level, and then slow cooled at various rates, to yield stratified enriched zones in the near-surface region of said parts. The enriched zones are characterized by the cobalt content decreasing, and the microhardness increasing, continuously through the enriched zones, and approaching values characteristic of the interior. The combination of stratified enriched zones in the near surface region and the 6% binder interior provide the toughness and deformation resistance required for heavy roughing applications. 
     A wide variety of cemented carbides, having different compositions and WC grain sizes, can also be carburized and slow cooled using the same techniques to yield stratified binder enriched zones having the same hardness profiles and cobalt content profiles as described above.
