Title: Echo canceller.
Inventor: THRANE MORTEN
IPC: H04M9/08
Filed: 1990-12-21
Abstract: This invention relates to an echo canceller such as for use in a full duplex hands free radio. The echo canceller is particularly suitable for use in a vehicle fitted with a microphone and a loudspeaker, for cancelling echos reach the radio microphone (16) from the radio loudspeaker (13). The signal paths are divided into sub-band channels (Y1-YM). Each of the channels has an adaptive filter (24, 29, 30), a time delay coefficient of which is dynamically adjustable. Means are provided for cancelling echos by compensating the signal on each channel as a function of the signal from the filter, and means (S1, Si, SM) are provided for initiating and suspending the adjustment of the coefficient of each channel filter as a function of the signal on that channel (X1-XM and/or Y1-YM).

Abstract: A meter driving system receiving pulse signals from a sensor is counting frequencies (F in ) or periods of the input signals. The counted results are weight-averaged to determine an output value (F n ) and a value (F m ) to be indicated. In a weight-averaging process, a weight (α) is varied in response to the frequencies (F in ) of the input signal. Thus, the meter can give a precise indication regardless of varying input frequencies.

Abstract: The automatic exchange of sliver cans at the spinning stations of a spinning machine presents difficulties, above all when sliver cans in the second row of sliver cans arranged in two rows have run empty. The sliver can standing in front of the can which has run empty and still delivering sliver first has to be cleared to one side for the exchange and is not permitted to disturb the can exchange. Moreover, the sliver flow-off from the can delivering sliver should not be impaired. By means of the can transport carriage according to the invention, an automatic can exchange, especially in respect of sliver cans in the second row which have run empty, is possible. For this purpose, the can transport carriage (16) has a further standing place (D) for a can. This standing place (D) next to the turntable (24) is arranged on the loading and unloading side assigned to the spinning machine (S). This standing place (D) serves for the temporary reception of a can (6) delivering sliver (13) to a spinning station, when a can (5) which stands behind this can (6) and which has run empty is to be exchanged for a full can (32). <IMAGE>

Abstract: 2.1. D-(-)-Pantolactone is an important intermediate in the synthesis of D-(+)-pantothenic acid or D-panthenol and can be obtained from the racemic compound by elaborate racemate resolution methods in the form of pantoic acid salts with chiral auxiliary bases and subsequent resolution of the pairs of salts with subsequent cyclisation of the pantoic acid. Since this synthesis is very elaborate, the object of the present invention is to provide a more suitable intermediate for pantolactone synthesis, which is to be obtainable straightforwardly and at low cost. 2.2. Such an intermediate is D-2,4-dihydroxy-3,3-dimethylbutyronitrile in an optical purity (D:L) of at least 80:20. D-(-)-pantolactone can be prepared in high yields by hydrolysis of the nitrile with concentrated acids. The nitrile is obtainable by reaction of hydroxypivalaldehyde with hydrogen cyanide in the presence of relatively large amounts of a D-oxynitrilase. 2.3.
