Abstract: A lead frame adapted for a plurality of semiconductor chips in which, for each semiconductor chip, at least one electric terminal is extended out of the package after encapsulation of the lead frame. In addition, a process for the production of a lead with this lead frame, enables a full automation of the lead assembly and good, reliable production. The lead frame has at least one mechanical node (T1, T2, T3, T4; T) at which, by severing a single reinforced node, at least three electric conductors (1, 2, G; 3, 4, G; 5, 6, G; 7, 8, G; 21, 22, 23) are electrically separated from one another.

Abstract: A filter bag is positioned inside and fastened to a holding frame. The holding frame has substantially vertical walls and is adapted to be placed on the edge of a coffee cup or the like. The sides of the holding frame that face the filter bag are made of hydrophobic material. The filter bag is made of nonwoven hydrophilic filter material.

Abstract: A flat, rectangular box 4 formed of cardboard contains a bag 18 of multi-layered foil material. A tube 24, which is disposed in the interior of the box in the transport condition of the package and can be removed from the box interior through an opening 10 which is closed by a tear-off strip, which is connected in liquid-tight manner to the bag 18 by a connecting piece. An outlet 36 provided at the free end of the tube is controlled by a pressure relief valve, which is provided in the tube and opens in the direction of the outlet. The walls of the narrow sides of the box each have a longitudinal fold along which these walls can fold outwards when the broad sides of the box are pressed together in order to empty the bag filled with a fluid, e.g. coffee extract. The one-way package is particularly suitable for use in a beverage vending machine in place of the storage containers employed until now.

Abstract: A continuously operative electrochemical ion exchange process for producing sodium, ammonium or magnesium sulphite or hydrogen sulphite in an aqueous solution simultaneously with the production of a useful calcium salt as a by-product by subjecting an aqueous solution of a salt of sodium, ammonium, or magnesium to an electrodialysis procedure with an aqueous solution of calcium sulphite or calcium hydrogen sulphite.
