Abstract: A circuit arrangement for centrally-controlled telecommunication exchange systems, particularly for time-division multiplex telephone exchange systems, with information exchange between sub-central devices, is characterized by the provision of an input/output processor device, in addition to the central control unit, which comprises an input memory portion and an output memory portion. The input memory portion is divided into sub-memories which receive information intended for a line trunk group and to be processed by the central control unit, while the output memory portion is divided into sub-memories which are assigned to respective buffers for information transfer between the sub-central devices, by-passing the central control unit.

Abstract: An alarm system for detecting the pattern of acoustic signals resulting from the breaking of glass utilizes transducers to convert the acoustic waves to electrical signals and then analyzes the signal strength, the frequency content and the pattern of the signal and no signal intervals to discriminate the breaking of glass from background or spurious noises. The system also determines the level of background noise and compensates therefor in determining whether an alarm signal is to be generated.

Abstract: When at least an anionic or non-ionic emulsifier which is hydrophilic and highly electrolyte-resistant, and neutralization products of alkyl- and/or alkanol amines with ethylene diamine tetra acetic acid, diethyldiamine penta acetic acid, and/or N-hydroxyethylene diamine triacetic acid or derivatives thereof are added to a leaf fertilizer, a fertilizer is obtained which is miscible with the highly concentrated ULV-pesticides and can be applied in common with these. The water evaporation during the application can be further reduced by the addition of at least one substance of the group polyalcohols, glycose syrup, sorbite, dispersible synthetic materials and polyhydroxycarboxylic acids.
