Title: Detector for arc discharge on overhead line - detects high frequency noise generated by fault to decouple circuit and sound alarm
Inventor: PAULS JOACHIM
IPC: H02H1/00
Filed: 1975-12-30
Abstract: Partial (4) and total (3) arc discharges on transmission lines, e.g. on insulators (2) are detected in order to activate alarm and trip functions. It is achieved by detecting the hf oscillations set up by the spark and using these as an alarm or trip signal. A suitable circuit isolator (5) e.g. an opto-electronic circuit, decouples the HV line (1) from the protection circuit. A filter unit (6) eliminates the standing hf components due to corona or line carrier signalling, and passes any genuine arc signal to a level detector (7). If the arcing passes a predetermined level a circuit is made to give alarm and/or trip the affected line.

Title: Tampon blank winding spindle has longitudinal slit - to receive and hold wadding strip pushed in laterally
Inventor: CREMER GERHARD
IPC: A61F13/20
Filed: 1976-02-27
Abstract: A machine for making tampon blanks comprises a winding spindle, which engages a continuously supplied strip of cotton absorbent wadding or the like, then rotates and winds it to form a cylindrical blank. The winding spindle comprises at least one longitudinal slit extending transversely to the longitudinal direction of the wadding strip, a pusher pushes the wadding sideways into this slit, so that it becomes trapped in the spindle. The system enables wadding of variable thickness to be handled effectively, by contrast with a previous arrangement in which rotating forks engage the wadding strip from its narrow side. It is thus not necessary to ensure uniform thickness of the wadding strip. In addn., it is not necessary (as with the forks) to execute a complete forward and return movement, totalling about 100mm, across the width of the wadding; in the present case, it is only necessary for the wadding to be pushed sideways across its width into the spindle.
