Title: Device for clearing a sieve or a screen
Inventor: NILL WALTER
IPC: B01D35/28
Filed: 1982-06-24
Granted: 1985-08-29
Abstract: In order to clean a screen in a waste water purification plant a surge of a body of water is generated by the agency of a dump flushing apparatus, which surge drops in a free fall towards the screen to be cleaned. This surge of cleaning water is given a dimensional extent which ensures for a substantially simultaneous impinging of the body of water onto the total extent of the screen. A framing which surrounds the screen encompasses this surge of water such as to guide the water and to force the water to flow through the screen. During the cleaning or flushing action the contaminants adhering to the screen, which contaminants are substantially of a thixotropic nature, will be removed from the screen and flushed through a sump towards the water purification section of the water purification plant.

Patent DE-3380576-D1 (DE)
Title: Speech recognition methods and apparatus
Inventor: BAKER JAMES
IPC: G10L15/00
Filed: 1983-03-28
Granted: 1989-10-19
Abstract: A speech recognition method and apparatus employ a speech processing circuity (26) for repetitively deriving from a speech imput (100), at a frame repetition rate, a plurality of acoustic parameters. The acoustic parameters represent the speech input signal for a frame time. A plurality of template matching and cost processing circuitries (28, 30) are connected to a system bus (24), along with the speech processing circuity, for determining, or identifying, the speech units in the input speech, by comparing the acoustic parameters with stored template patterns. The apparatus can be expanded by adding more template matching and cost processing circuity to the bus thereby increasing the speech recognition capacity of the apparatus. The speech processing circuity establishes overlapping time durations for generating the acoustic parameters and further employs a sinc-Kaiser smoothing function in combination with a folding technique (113) for providing a discrete Fourier transform (112). The Fourier spectra are transformed using a principal component analysis (122) which optimizes the across class variance. The template matching and cost processing circuitries (28, 30) provide distributed processing, on demand, of the acoustic parameters for generating through a dynamic programming technique the recognition decision. Grammar and word model syntax structures reduce the computational load. Template pattern generation is aided by using a "joker" word to specify the time boundaries of utterances spoken in isolation.
