  • Patent number: 6758993
    Abstract: A system and method is disclosed that uses an empirically-derived thermal transfer function for an ignition coil taken with respect to an ambient temperature and responsive internal temperatures. The system combines the transfer function with a minimum cure-induced stress profile, in order to obtain a time-temperature profile for minimizing cure-induced residual stress in an epoxy resin impregnated ignition coil. An accelerated minimal-stress profile is obtained by increasing an initial gel isotherm temperature of the above-mentioned time-temperature profile.
    Type: Grant

  • Patent number: 6338749
    Abstract: A system is provided for de-gassing a material. The system includes a vessel and a material distributor. The vessel has an internal chamber in which a vacuum can be maintained. The material distributor is located inside the internal chamber and is adapted to distribute the material to be degassed as a thin film along at least one wall of the vessel in such a way that exposure of the thin film to vacuum within the internal chamber causes entrained air or other gasses from the material to be withdrawn from the thin film. Also provided is a method for degassing a material. Preferably, a material distributor is inserted into a vessel where degassing of a material is to be performed. The material distributor can comprise an inlet for the material to be degassed, a scaling lip, a film-forming lip, and a material distribution cavity. The sealing lip is adapted to sealingly engage at least one wall of the vessel. The film-forming lip is spaced apart from the sealing lip.
