Patent DE-4011800-A1 (DE)
Title: Continuous piece goods winding - by inserting trolley with empty reel under fabric to take up cut end without interrupting material movement
Inventor: GLAESER DIETER DIPL ING
IPC: B65H19/28
Filed: 1990-04-12
Abstract: To wind fabric piecegoods continuously on to a winding trolley, the trolley with an empty reel is moved into the winding station against the direction of fabric movement below the material between the fully wound roller and the feed. The fabric is led to the empty reel and held by a fixed contact roller. The fabric is cut laterally at the full roller to give a new end to start winding round the new reel. During the winding action, the contact roller and reel are pressed together at an adjustable pressure and, shortly before winding is complete, the trolley is moved into a final position. When in the final position, the fabric web is raised before the trolley with the new reel is positioned, and the trolley is moved to an end position directly after the end of the fabric has been wound in place. The laying mechanism (5) has a fixed contact roller (8) and an entry station (12) between the winding point (3) and the finished winding point (9) to pass the fabric (2) round the reel (14) on the empty trolley (13). The fabric movement is not affected by the insertion of the empty reel trolley (13) parallel to the fabric (2) movement. The contact roller (8) has a drive system and is secured to the fabric treatment machine (1). The transport uses a lifting trolley (15) with powered drive. ADVANTAGE - The technique is suitable for fabrics which are sensitive to tension, and for those which are wound at high tension, to give an uninterrupted reel winding process.

IPC: C07C37/20
Filed: 1990-05-10
Abstract: Prodn. of alkylphenols or bisphenols from a phenolic starting material derived from the processing coal-derived prods. or waste waters is effected by (a) activating the starting material by contact with a cation exchanger in acid form at 20-60 deg.C. for 10-90 min., (b) reacting the activated material with a reactant (I) selected from olefinic aliphatic cpds., ketones and aldehydes in the presence of a sulphonated cation exchanger in acid form at 50-130 deg.C., and (c) treating the prod. with a weakly or moderately basic anion exchanger in basic form.

Patent DE-4101819-A1 (DE)
Inventor: KONSTANZER MICHAEL ING GRAD
IPC: G01R27/14
Filed: 1991-01-23
Abstract: A measuring device (1) is used for electrically measuring a resistor (3) forming a measuring sensor (2), which can be formed, for example, by a Pt100 resistor. A storage capacitor (11) is connected in parallel with this resistor (3). The measuring resistor (3), together with the storage capacitor (11), is connected to a measuring instrument (5) via two lines (4). The line length can be several metres in this arrangement. A power source (10a, 10b) can be used for sending a constant measuring current through the measuring circuit. Across the resistor (3), a voltage proportional to the current is dropped, to which voltage the parallel-connected storage capacitor (11) is also charged up. If the constant current is then disconnected, the charging voltage of the storage capacitor (11) can be remotely measured without voltage drops occurring across the line resistances since measuring takes place virtually without current. In this measuring method, thermal voltages occurring in the measuring circuit can also be taken into consideration. <IMAGE>
