  • Lubricating and anti-tack compositions useful in the shaping of thermoplastics containing mixed esters and esters of C.sub.32-72 monoalcohols with C.sub.18-72 monoacids
    Patent number: 4157990
    Abstract: Mixtures of (A) mixed esters of (a) C.sub.2-10 alkanepolyols, (b) certain dicarboxylic acids, and (c) C.sub.12-30 aliphatic hydrocarbon monocarboxylic acids, said esters having hydroxyl and acid numbers of 0 to 6 and having a molecular weight above 524, and (B) esters of C.sub.32-72 aliphatic monools with C.sub.18-72 aliphatic hydrocarbon monocarboxylic acids (the weight ratio of A to B being between 9:1 and 1:3) are useful as lubricants and detackifiers in thermoplastic molding compositions.

  • Distortion corrector for the adaptive base band correction of a phase-modulated signal
    Patent number: 4140974
    Abstract: Apparatus is described for adaptively correcting distortion in phase modulation signals following demodulation. Binary signals indicating the position of a signal vector of the demodulated signal for each modulation period are formed, and from this an indication of the error angle of that vector is obtained. A corresponding fault signal controls adjustment of the demodulated signal applied to a decoder to provide for distortion correction.
