  • Patent number: 5935405
    Abstract: Rigid or flexible circuits of electrically conductor tracks can be produced on flexible or rigid, non-conductive support materials bya) coating the surfaces of the support materials including existing drill holes with a primer and a conductive polymer, preferably poly-3,4-ethylendioxythiophene, which may contain binders,b) applying an electroplating resist in the form of the negative image of the conductor tracks,c) metallizing by electroplating the surface kept free by the electroplating resist, including existing drill holes, in the form of the positive image of the conductor tracks,d) removing the electroplating resist ande) removing the conductive polymer, which had been below the electroplating resist, or converting it to a non-conductive form, wherein the conductor tracks are electrically interconnected during the metallizing step by the layer of conductive polymer, thereby avoiding the need to individually contact each conductor track.

  • Patent number: 3991015
    Abstract: High molecular weight aromatic copolyamides which contain a small proportion of structural units having 2,3-(1H,3H)-quinazoline dione rings are disclosed. The presence of quinazolinedione ring units in the copolyamide results in an increased moisture absorption capacity. By using small amounts of quinazoline dione units, the good physical properties of the corresponding quinazoline dione-free polyamide are substantially retained while the moisture absorption is significantly increased. Larger amounts of quinazoline dione units than contemplated (15 mol percent and more) do not improve the moisture absorption further and adversely affect the physical properties. The copolyamides are useful in textile applications in which the improved moisture absorption serves to make clothing prepared from such textiles more comfortable.

  • Patent number: 3932409
    Abstract: 2-Phenyl-4(3H)-quinazolones bearing a urethane or thiourethane group on the 2-phenyl substituent, a second urethane or thiourethane group on the benzo ring of the quinazolone nucleus and an alkyl, cycloalkyl or phenyl group in the 3-position are prepared by treating the corresponding bis-amino compound with an acid derivative or the corresponding bis(isocyanate) or bis(isothiocyanate) with an alcohol. The compounds, of which 2-[3'-(methoxycarbonylamino)-phenyl]-3-phenyl-6-methoxycarbonylamino-4-(3H )-quinazolone is a typical embodiment, are cytostatic agents.
