  • Composition based on high molecular weight organotin maleates which can be used to stabilize thermoplastic polymers, process for producing the said compositions
    Patent number: 5985967
    Abstract: The invention relates to a composition containing high molecular weight organotin maleates as obtained by reacting a high molecular alcohol or epoxyalkane with maleic anhydride and by then bringing the mixture thus obtained into contact with a dialkyltin oxide.The invention also relates to the poly(vinyl chloride) (PVC) compositions stabilized using the said composition based on high molecular weight organotin maleates and also to the extruded rigid items formed from the said PVC compositions.

  • Digital filter with integrated decimation
    Patent number: 4972357
    Abstract: A digital filter with integrated decimation shapes a sampled signal and reduces its sampling rate. The filter includes, in cascade, a prefilter (5), a decimator stage (8) and an equalizer (9). The prefilter is a simplified FIR filter in which only logical operations are performed; all multi-digit multiplications are performed only in the equalizer, at the reduced sampling rate. This results in a filter having increased throughput and/or occupying a reduced area.
