The invention relates to a method for producing nitrocellulose-based carbon black in the form of chips. The recipe constituents are blended into a mixture and converted at an elevated temperature into a dispersion in a suitable device which achieves the desired degree of kneading such as a kneading machine or roller die extruder. The dispersion is then calendered into a film, the film is cooled an...

Crop protection agents based on aqueous emulsion concentrates containing, as dispersing agents, phosphorylated block copolymers based on propylene oxide and ethylene oxide, optionally containing a nucleus of fatty alcohol, or salts of these block copolymers.

DC current fed, preferably accumulator-driven, power plant for generating an AC voltage V2. The power plant comprises a DC current fed oscillator circuit KR1, C1, C2 for generating AC current pulses to the primary winding of a transformer TR for stepping up the said AC current pulses to suitable AC voltage on the secondary winding of the transformer TR. Sensor circuits D11, D12, R23, OPT1 detectin...

A conductor (3) is provided between first (1) and second rotary bodies. The conductor (3) is divided into two, one part being connected to a roller bearing, the second part being likewise connected. Where several conductors (3) require to be used or where several signals are to be transmitted through separate conductors, these are divided into two parts which are in turn connected to their own rol...

The box is produced by folding a stamped-out cardboard body, and has a cover (30) with side parts (33a,33b) which, in the closed condition of the box, locate against the insides of corresp. box slides (6a,7a,6b,7b). The cover has fold lines (35a,35b) at half of its height which are at right-angles to the fold lines (32a,32b) which limit it from its sides. - Normally the cover side parts are folded...
