Patent DE-2825082-A1 (DE)
Inventor: MOSHIER STEPHEN L
IPC: G10L15/00
Filed: 1978-06-08
Abstract: A speech recognition method for detecting and recognizing one or more keywords in a continuous audio signal is disclosed. Each keyword is represented by a keyword template representing a plurality of target patterns, and each target pattern comprises statistics of each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio. The 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 by means of likelihood statistics with the target patterns of the keyword templates. A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.
Patent DE-2827477-A1 (DE)
Inventor: RIEHM THEODOR DIPL CHEM DR
IPC: C13K13/00
Filed: 1978-06-22
Abstract: A process for producing polyalcohols such as xylite from deciduous wood wherein the wood is hydrolyzed with dilute mineral acid to produce a sugar solution which is deionized and decolorized in an ion exchanger and hydrogenated to produce a polyalcohol solution which is also decolorized and deionized by ion exchange and from which pure polyalcohol is thereafter separated by crystallization, further comprising dispensing with neutralization of the acid in the sugar solution after hydrolysis, deionizing and decolorizing both the sugar solution and the polyalcohol solution in the same ion exchanger, eluting acetic acid taken up by the ion exchanger from the polyalcohol solution and displacing polyalcohol solution from the exchanger with the acid containing sugar solution, washing the ion exchanger with water only after ion exchange of the sugar solution, removing the bulk of the acetic acid from the sugar solution by evaporating the sugar solution to a higher concentration than the concentration customarily utilized for hydrogenation, and rediluting the sugar solution prior to hydrogenation with the exchanger wash water.

Title: Casting metal from bottom pour ladle into mould - where casting pipe extends to bottom of downgate and has inlet for injecting inert gas at top
IPC: B22D27/00
Filed: 1978-07-13
Abstract: On the bottom of the ladle is an outlet nozzle surrounded by a casting pipe (3); and the bottom end of pipe (3) is near the base of a vertical downgate (6) in the mould. At the base of the downgate (6) is a horizontal runner(9) leading to the mould cavity, but the runner(9) is initially closed by a meltable disk (10). The result is that the downgate (6) can be filled with molten metal, pref. in the absence of air by injecting an inert gas into pipe (3); and then disk (10) melts so the metal flows quietly into the mould cavity. An air-tight joint pref. exists between the bottom of the ladle and the top end of pipe (3). The mould is filled quietly by the metal without turbulence and in the absence of air, thus avoiding the inclusion of dross etc. in the castings.

Title: Multilayered, structured-surface floor and wall coverings - by screen printing ground fabric with different gauge stencils
Inventor: HOEVER ALEXANDER
IPC: B41M3/18
Filed: 1978-12-27
Abstract: A paste of synthetic materials is applied to form the wearing surface of a multi-layered, patterned and surface-structured floor or wall covering.

Title: Remote pressure measurer with sensor - uses coded disc. optical reader and digital optical signal transfer via optical fibre
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G01L9/00
Filed: 1979-05-08
Abstract: The device for remote measurement of pressure has a sensor undergoing a pressure dependent deformation and/or displacement which is converted into a signal by a code disc and sensor. The signal is then fed to a remote point for further processing. The coded disc reading and signal transfer are performed independently of noise differences between the measurement sensor and the signal processing point. The coded disc has transparent and opaque regions arranged to form the code which is read using a light source and receiver. The light is conducted to the disc by an optical fibre from the source and from the disc to the signal processing point via a second fibre. Digital light signals are thus prod. and transferred. They may be directly displayed or converted into electrical signals.
