Tubular shaped filter elements are often coupled with each other in series to produce assemblies which must be cleaned from time to time. The novelty is that rotary air filter jets are mounted on an H-frame which is secured to a central tube rotating on bearings. USE/ADVANTAGE - This type of rotary air jet can be constructed using a single central bearing for each filter jet unit. The jets can be...

The invention relates to a process for the preparation of positive or negative active mass of lead accumulators by using the active mass separated from production-refuse plates and/or the active-mass wastes produced during production. According to the invention when positive active mass is prepared then positive active mass, while when the negative active-mass is prepared then negative active-mass...

Nach einer Fadenunterbrechung und einer anschließenden Wiederherstellung der Fadenverbindung an der Spulstelle einer Textilmaschine muß der Faden in seine normale Fadenlauflage an den Fadenführer der Spulstelle übergeben werden. Die Übergabe des Fadens erfolgt aber in der Regel nicht in Abstimmung mit der Bewegung des Fadenführers, wodurch der Faden über eine gewisse Zeit an ein und derselben Stel...
