Patent DE-3236832-A1 (DE)
Inventor: MOSHIER STEPHEN LLOYD
IPC: G10L15/10
Filed: 1982-10-05
Abstract: A speech recognition method and apparatus for recognizing word strings in a continuous audio signal are disclosed. The word strings are made up of a plurality of elements, and each element, generally a word, is represented by an element template defined by a plurality of target patterns. Each target pattern is represented by a plurality of statistics describing the expected behavior of a group of spectra selected from plural short-term spectra generated by processing of the incoming audio. Each target pattern has associated therewith at least one required dwell time position and at least one optional dwell time position. The number of required dwell time positions and the sum of the required and optional dwell time positions define, in effect, the limits of a time interval during which a given target pattern can be said to match an incoming sequence of frame patterns. The incoming audio spectra are processed to enhance the separation between the spectral pattern classes during later analysis. The processed audio spectra are grouped into multi-frame spectral patterns and are compared, using likelihood statistics, with the target patterns of the element templates. Each multi-frame pattern input, which inputs occur at a frame rate which requires each keyword target pattern to correspond to at least two of the multi-frame patterns, is forced to contribute to each of a plurality of pattern scores as represented by the element templates. The contributions of said multi-frame pattern inputs to said pattern scores is controlled, in part, by said required and optional dwell time constraints. A concatenation technique is employed, using dynamic programming techniques, to determine the correct identity of the word string.

Patent DE-3248054-A1 (DE)
Title: Method and arrangement for covering areas of objects to be worked on, in particular car bodies, which are to be protected against soiling or damage, by means of a protective tarpaulin
Inventor: IHMELS MANFRED
IPC: B05B12/26
Filed: 1982-12-24
Abstract: Areas of objects to be worked on, such as door and window openings of car bodies, are covered by a tarpaulin during the work, e.g. grinding or painting, the tarpaulin being fastened to the edge of the covering area by means of adhesive strips. Here, the tarpaulin is joined to the adhesive strip on the car body not by means of adhesive bonding, but by means of touch-and-close ("Velcro") bonding. Consequently, the tarpaulin can be designed for repeated use and produced solidly from hard-wearing material and can itself be firmly joined to a touch-and-close strip. The adhesive strip to be attached to the car body or other object to be worked on is provided, for touch-and-close joining, at the top with an e.g. velour-like surface; it can for its part be adhesively bonded to the car body before the work; if desired, borders of the areas to be covered can even be constructed equipped with a velour-like or other touch-and-close surface, so that it is unnecessary to prepare the object each time for the work to be carried out by attaching an adhesive strip.

Title: Process for the addition of reactive metals to steel
Inventor: WILSON WILLIAM G
IPC: B22D1/00
Filed: 1983-07-13
Abstract: A process is described for the addition of reactive metals to continuously cast steel, which avoids the difficulties of the tundish nozzle becoming blocked. According to the process, the molten steel is continuously cast through a tundish nozzle while reactive metal is added to the molten steel in a form and at a place either above or below the tundish nozzle, such that high-melting oxides and/or oxysulphides of the reactive metals are not formed in a quantity sufficient to block the nozzle before the steel passes through the nozzle. Alternatively, a melting auxiliary can be added during or after the addition of the alloying element, reducing the melting point of the reactive products to a temperature which is below the temperature at which the steel passes out through the tundish nozzle.

Title: Method and device for treating material with a high-pressure blast
Inventor: KOEHLER GUENTHER
IPC: B24C1/00
Filed: 1983-12-02
Abstract: A method and a device for treating material, in particular for eroding, smoothing, cutting, boring or cleaning, with a high-pressure blast is to be improved in that the jet emerging from a nozzle is already dissolved into droplets shortly after leaving the nozzle mouth without loss of energy. As a result, not only the speed of the jet consisting of individual droplets is to be increased, but its breakdown effect is also to be enhanced. This is achieved in that the high-pressure blast is applied to the surface of the material to be treated from a double-jet or multi-jet nozzle whose jets touch one another in the region of the still coherent jet, that is to say the jet core or the compact jet of constant speed. The jet is applied with such a spacing of the nozzle mouth from the surface to be treated that the surface lies in, or shortly after, the beginning of the breakup of the combined jet or of the dissolution into droplets of the high-pressure blast.

Title: Centrifugal separator
Inventor: WANTKE JOHANN DIPL ING
IPC: B01D45/14
Filed: 1983-12-13
Abstract: The invention relates to a centrifugal separator for removing dust, snow and water drops from the cooling air of an electric machine. The separator comprises a cylindrical casing, an air stream guide and a trap, having an annular cross-section attached to the cylindrical casing, for the impurities. In addition, an axial counter-current fan is arranged in the cylindrical casing and, on the air outlet side of this, the axial air stream guide is arranged. This has, on the one hand, at the air outlet side of the counter-current fan, radially three-dimensionally bent guiding vanes and, on the other hand, at the end guiding vanes bent in the opposite direction. The latter guiding vanes are attached in the interior to the cylindrical trap which has an annular opening. The curvature of the guiding vanes and the distance of the top guiding vanes to the opening of the trap is decisive for the efficiency. The advantage of the invention is a considerable improvement in the separation efficiency.

Title: Device for coating planar workpieces with materials which are capable of flowing
Inventor: GRAF ROLAND
IPC: B05C1/02
Filed: 1984-08-07
Abstract: A device for coating planar workpieces with materials which are capable of flowing has an application roller and a counter-roller, between which the workpiece is pushed through, and a metering roller. The adjustment of the contact pressure, and thus the metering of the material, between application roller and metering roller takes place by means of two threaded spindles, in each case a hydraulic cylinder being arranged between the end side of the threaded spindles and the bearing of the metering roller coaxially with respect to the threaded spindle, and the fluid spaces of the two hydraulic cylinders being connected to one another. In this way it is ensured that, even with imprecise adjustment of the threaded spindles, a uniform application of force on the two bearings of the metering roller and thus also a satisfactory application of the coating material can be achieved.
