Abstract: Process for the purification of 1,1-dichloro-1-fluoroethane. To remove the unsaturated impurities such as 1,1-dichloroethylene and dichloroacetylene, the crude 1,1-dichloro-1-fluoroethane is subjected to the action of chlorine and/or of a hydracid, this treatment being performed in the presence of a Lewis acid or, only in the case of chlorine, by photochemical catalysis.

Inventor: RAITH ALEX KRISTER
IPC: H04L27/14
Filed: 1990-01-04
Abstract: The invention relates to a method and an arrangement for con­trolling the frequency of a radio-receiver which receives signal-­sequencies which have been subjected to interference and which include a synchronizing-sequence and a data-sequence. A signal-­sequence is A/D-converted (3) to signal-points (I,Q) intended for analysis, and a Viterbi-algorithm (10) is adapted (12,13) to the prevailing interferencies with the aid of the synchronizing-­sequence. The data-sequence is Viterbi-analyzed through a large number of calculating stages, for the purpose of determining the bit-sequence of the data-sequence. According to the invention, a bit-sequence is extracted during the Viterbi-analysis, with a time-delay (TE), subsequent to effecting a few calculating stages, and a corresponding extracted signal-point is calculated (14). The analysis-intended signal-point corresponding to the extracted signal-point is divided and time-delayed (16,TE), and phase-compared (15) with the extracted signal-point. Correspon­ding phase-comparisons are made with respect to consecutive signal-points in the data-sequence and the angular magnitudes obtained in the phase-comparison are low-pass filtered and integrated (17) to form an angle-shift signal (V). The analysis-­intended signal-points are displaced angularly (11) by the angle-­shift signal (V) prior to the Viterbi-analysis.

Abstract: A signal transfer control system of PC (programmable controller) for transferring input/output signals to and from external units. An I/O unit (26) has an input/output signal region (1) for storing input/ouput signals relative to an external unit, and a mapping data (2) for defining the mapping of input/output signals (1). A RAM (23) on the PC side has a point data (3) for defining a destination address from the mapping data (2), and has an input/output data region (4) for storing the input/output signals. The input signals are stored in the input/output signal region (1) and are mapped by the mapping data (2) for each of the input signals. The point data (3) determines the destination of the mapped input signal. The destination of the input signal is determined by the mapping data (2) and the point data (3), and is transferred to the input/output data region (4). The output signal is transferred from the input/output data region (4) to the input/output signal region (1) by the point data (3) and the mapping data (2) just contrary to the above. Even when the arrangement of the input/output signals is changed, the point data or the mapping data only need be changed to cope with it without changing the sequence program.
