  • Patent number: 5114831
    Abstract: These photopolymerizable laminating materials consist of at least one film-forming polymer as a binder, at least one organic compound which is compatible with the binder, has at least two double bonds capable of addition polymerization and may be partially replaced by an organic compound having only one double bond capable of addition polymerization, a photoinitiator or photoinitiator system and an adhesion promoter, with or without conventional additives and assistants, the adhesion promoter used being a tricyclic heteroaromatic compound which is soluble in aqueous alkaline solutions.The said laminating materials are suitable for the production of printed circuits.

  • Patent number: 4220269
    Abstract: A slide gate nozzle for a slide gate carried by a closure frame which includes two independent arms pivotally connected with a casting vessel for slidably moving the slide gate with respect to the casting vessel and for moving the slide gate away from the vessel to facilitate changing of the ceramic plates. Rocker frames are pivotally connected with the arms and include rollers on which a guide rail rides in the sliding direction of the slide gate, and the swivelly connected rocker frame assures even pressure of the ceramic plates.
