Title: DC interruption detection circuit for telephone line - senses sign changes in difference between slowly and rapidly reacting current sensor outputs
Inventor: BOECKMANN GERHARD
IPC: G01R31/02
Filed: 1991-08-21
Abstract: A circuit for detecting an open circuit in a d.c. line contains a detector unit (3a) connected into the line (9) via two connectors (4, 5). The detector unit produces one output voltage (Ua) varying rapidly with the current in the line and another (Uk) varying slowly with the current. In normal operation the difference between the voltages is essentially proportional to the curent in the line. If the current in the line falls rapidly, the sign of the voltage difference changes in a time independent of the initial current level. USE/ADVANTAGE - Reliable detection of open circuit in d.c. conductor independently of current level and without delay.

Title: Stacking equipment for metal sections - comprises conveyor, stoppers, lifting tables, turn-over mechanism and bundling unit for stacking pairs of sections in close packed layers
Inventor: SALONEN SEPPO
IPC: B65G57/18

The first stopper is positioned at distance J in the direction of travel from the rotation axis of the turning mechanism and the second stopper is at distance O in the opposite direction from the same axis. The two distances (J,O) are set, so that in turning over the section held firmly against the swing arm of the second stopper, the turned over section is nested in the open section lying at the first stopper with a small offset in either transport direction. USE/ADVANTAGE - For formed metal sections, esp. of channel form, in close packed layers by nesting pairs of sections in mirror image with an offset in either direction. Adjustment for varying section size is simple and the equipment operates reliably.

Title: Yarn winding machine with plural cross connection - has traverse mechanism with grooved roller and parallel rails to cross-wind on a reel, with reduced delay and acceleration at changeover
Inventor: ZINGSEM MARTIN
IPC: B65H54/28
Filed: 1991-11-28
Abstract: A yarn winding machine is employed to cross wind yarn to a number of reels. The reels have a common axis. The cross winding is performed by a traverse mechanism with advance and return, driven by a grooved roller and parallel rails, with direction change at each end. The number of yarn guides equals the number of reels times two plus one, and each guide has unidirectional connection between rail and grooved roller. ADVANTAGE - By cross connection of more than one reel wind, the delay and acceleration at each end of the cross wind section is eliminated, and substituted by a return at each end of the group. This results in an improvement in the winding.
