  • Method for producing a hybrid frame or hybrid housing and corresponding hybrid frame or hybrid housing
    Patent number: 6743663
    Abstract: The invention relates to a method for producing a hybrid frame (1) or hybrid housing. According to said method, a leadframe (3) with soldering and/or bonding tags (3a), made from a plated strip, is placed into an injection mould and moulded with plastic in order to form a housing part (2) of the hybrid frame or the hybrid housing (1). According to the invention, the soldering and/or bonding tags (3a) of the leadframe (3) are kept in the injection moulding die at least during part of the injection-moulding process, by means of a plunger.

  • Preparation of dihydroquinacridones, quinacridones and quinacridonequinones
    Patent number: 4956464
    Abstract: Dihydroquinacridones, quinacridones and quinacridonequinones are prepared by cyclizing 2,5-dianilino-3,6-dihydroterephthalic acid derivatives or 2,5-dianilinoterephthalic acid derivatives in the liquid or solid state or in solution, in each case in finely divided form, or in the gas phase, in the presence or absence of an oxidizing agent.

  • 3-tert-butyl-4-hydroxyphenylpropionic acid amino-alkylamide derivatives
    Patent number: 4785107
    Abstract: The novel phenol derivatives of the general formula (I) ##STR1## where R is hydrogen, straight-chain or branched C.sub.1 -C.sub.8 -alkyl or cycloalkyl, A is a bridge member and B is a radical of the formula ##STR2## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and T.sup.1 independently of one another are each hydrogen, C.sub.1 -C.sub.8 -alkyl, halogen, CN, COOT.sup.2 or CONHT.sup.2, with the proviso that one or more of the radicals R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and T.sup.1 are halogen, CN, COOT.sup.2 and CONHT.sup.2 and T.sup.2 is C.sub.1 -C.sub.8 -alkyl, are useful for stabilizing organic material, in particular polyolefins, to degradation by oxidation.

  • Branched, high molecular weight, thermoplastic polyarylene ethers containing nitrile groups, and their preparation
    Patent number: 4567248
    Abstract: Branched, high molecular weight, thermoplastic polyarylene ethers which contain nitrile groups and are composed of repeating units of the formula I--E.sub.1 --O--E.sub.2 --O--where E.sub.1 is a radical derived from a dihalobenzene compound and E.sub.2 is a radical derived from a bisphenol, and contain from 0.01 to 5 mol %, based on the radical E.sub.1, of one or more radicals derived from polyhalo compounds of the formulae ##STR1## where X is fluorine or chlorine, and their preparation.
