Title: Servo-controller with motor and position indicator - has power failure indicator and switches to emergency power source to allow uninterrupted flow of data
Inventor: TSUTSUMI SEISUKE
IPC: G05B19/4062
Filed: 1993-10-27
Abstract: The servo-controller has a primary voltage source (22), and a data transmission cable. One end of the cable is connected to a position indicator (110) and the other end of the cable is connected to a control device (114). An emergency voltage source (23) is included for the position indicator and the control device. A power outage indicator (101, 103) is provided. When a power outage occurs, the power failure indicator activates a switch which allows transmission of data along a path (43) supplied by the emergency power source. Parallel-to-series and series-to-parallel converters are provided, and these help to determine whether or not the cables (38, 30, 42, 43) are connected correctly. USE/ADVANTAGE - For control rectifier part for servo-motor. No special cable is required to switch to emergency power source.

Title: Method and circuit arrangement for improving the quality of voice communication in hands-free telephone facilities
Inventor: SCHUETZE HELMUT DR ING
IPC: H04M9/08
Filed: 1993-11-04
Abstract: The invention is based on the object of combining the methods of echo cancellation and of noise reduction, known per se, with one another in such a manner that they mutually reinforce one another in the reduction of the interfering signal components. According to the invention, an estimated echo value of the received signal is generated by balancing the echo path in the echo canceller and this value is subtracted from the transmitted signal at the correct time. An estimated value of the original undisturbed voice signal generated by the noise reducer is transmitted to the echo canceller via a feedback branch and subtracted from the transmitted signal at the correct time. The solution according to the invention is preferably used in telephone networks with hands-free facilities. <IMAGE>

Abstract: Removal of residues (I), esp. unfixed dyes, dye degradation prods. and residual chemicals and/or additives from textile substrates involves treatment with an aq. liquor (II) for a certain time. The novelty is that the amts. of fresh (II) supplied to the appts. and contaminated (II) discharged are reduced as treatment proceeds.  Also claimed is the appts. used.  Pref. corresponding reductions are made in both amts., pref. continuously. Treatment is carried out at 15-98 deg C, pref. initially at 60-80 deg C, then at increasing temp., whilst the (II) temp. at the end of treatment is varied between 15 and 40 deg C. The temp. is regulated by the temp. and amt. of fresh (II) supplied. The fresh (II) is treated with additive in decreasing amts. The treatment time is 10-90 mins. At the end of treatment, the substrate is reacted again, esp. with (continuously) increasing amts. of fresh (II) or drained and rinsed with fresh (II).
