  • Patent number: 3985931
    Abstract: A surface treating device to be attached to the upstream end of a cooling and sizing mandrel used in the manufacture of a web of expanded polystyrene of a general purpose grade from a warm, tubular extrudate of such material, such treating device serving to prepare the dense, radially innermost surface of such tubular extrudate so that it can be drawn over the cooled, cooling and sizing mandrel in tight, surface to surface contact therewith to substantially reduce the amount of material from the web which accumulates on the cooling and sizing mandrel.

  • Patent number: 3958074
    Abstract: A high voltage electric power transmission line having an electrical power carrying capacity of 50 megawatts or more. An electrical power conductor is contained within a substantially rigid dielectric casing formed of a plurality of elongated tubular glass casing sections hermetically bonded together linearly end to end forming a continuous elongated casing around the conductor. The casing is loosely contained in an outer duct which permits lateral movement of the casing in the duct but places a maximum limit on such movement.
