  • Patent number: 4897312
    Abstract: Insulated electrical conductor and electrical insulation which includes a polyolefin as polymeric base material and a voltage stabilizer included in the polyolefin and comprised of at least one hydrolyzable alkoxy compound, which at least one hydrolyzable alkoxy compound is a liquid at a temperature ranging from about -25.degree. C. to about 140.degree. C. and has a formula:(R.sup.a O).sub.y R.sub.3--y.sup.b X-[R-X'(OR.sup.c).sub.z R.sub.2-z.sup.d ].sub.n -OR.sup.e,where R.sup.a, R.sup.c and R.sup.e are hydrocarbon groups having 1 to 18 carbon atoms; R.sup.b and R.sup.d are saturated or unsaturated, substituted or unsubstituted aliphatic hydrocarbon groups or aromatic hydrocarbon groups having from 1 to 30 carbon atoms; R is a group having a carbon skeleton including at least one heteroatom Y; O is oxygen; X and X' are elements having a valence of four; n varies from 1 to 10, y varies form 0 to 3, z varies from 0 to 2, and where R, R.sup.a, R.sup.b, R.sup.c and R.sub.

  • Patent number: 4769745
    Abstract: A process of sealing a housing having a radially projecting rim around an open end of the housing using a gasket of a similar thermoplastic material as the lid and a bonding ring also of the thermoplastic material comprising positioning the gasket between the lid (2) and the rim (7), and the bonding ring below the rim, and in contact with the lid, and pressing the lid onto the gasket while welding the ring to the lid.A process is described for the hermetic sealing of a can-shaped housing of an electrical component with a lid, and a gasket between a housing rim protruding outwardly of the housing top and lid, that permits short process times and leads to components that are suitable for higher voltages with small dimensions. A bonding ring of thermoplastic synthetic material is laid under the housing rim of the metal housing. After the installation of the gasket of the same thermoplastic synthetic material as the lid between the housing rim and the lid, the lid brought into contact with the bonding ring.
