  • Patent number: 6383033
    Abstract: A terminal side load electrical connector positions a series of terminals of a flex circuit into a core in unison. The core has a peripheral surface extending between a contact surface and a conductor surface. The terminals are assembled to the core through the peripheral surface. A housing has a conductor opening opposite to a contact opening. The core with the pre-assembled terminals insert into the housing through the conductor opening. The contact surface of the core is exposed through the contact opening of the core. The housing engages the peripheral surface of the core thereby preventing the disengagement of the terminals from the core.

  • Patent number: 5201152
    Abstract: A containment device for contaminated building demolition. A pre-engineered rigid steel frame building is supported on rail trucks movable on railroad tracks. The railroad tracks are positioned on opposite sides and along the length of the contaminated building to be demolished. The rigid steel frame building has one open end and is sized larger than the width and height of the contaminated building. This allows a portion of the contaminated building to be movably enclosed by the pre-engineered building. A flexible liner material inside the pre-engineered building, at the open end attached to the contaminated building, and at the bottom of the pre-engineered building draped to be in contact with the ground seals off the interior of the pre-engineered building to prevent the release of contaminated particles during demolishing operations. A hoist and cable are used to move the pre-engineered building on the railroad tracks.
