The disclosure relates to an ultrasound unit comprising an annular tool (4) or sonotrode intended for welding packaging containers with circular cross section. The tool (4) has a mass plane (10) located at a right angle to the centre axis (8) of the tool, and with a mean circumference (6) whose length is adapted to the wavelength of the ultrasound source. With a view to making possible the welding...

An arrangement and a method for synchronizing data to a local clock. The invention incorporates a self-tested self-synchronous two-phase input port, wherein a line or an element of parallel data is tested for data read failure using two different phases or edges of the local clock. If a data read failure is detected using one phase, the other of the two phases is selected for reading the data. The...

At least one layer of paper (6) or absorbent material in the base (5) of the toilet bowl (2) is supported by a conveyor belt (7) that forms the base and can transport the paper and effluent (3) to a discharge position (8), allowing excrement to be disposed of separately from urine.

A rotatable knife roll with at least one foil knife secured on a portion of the body of the roll and having a sharp and endless cutting edge closed within itself to cut out window openings. There are breakthroughs for suction apertures arranged within the cutting edge. There is at least one suction-air control valve arranged on the face side of the roll body. The valve is rotatable relative to thi...
