Abstract: A package assembly for transporting hazardous materials including a bottle containing a hazardous material disposed within a metal can wherein the bottle is surrounded on all sides by individual upper, lower and side absorbent non-resilient and frangible synthetic resin foam elements. The foam elements provide cushioning for the bottle and absorbency in case of spillage. The individual foam elements are maintained out of contact with each other by means of fiberboard spacers. The spacers are disposed to separate the upper and lower ends of the bottle from the resin foam and to protect the frangible foam from disintegration due to abrasion by the bottle. The metal can be suspended within an outer corrugated fiberboard box by means of a fiberboard insert element for the outer box. The fiberboard insert element supports the can out of contact with the outer fiberboard box and provides a protecting buffer zone between the can and the walls of the outer fiberboard box for the protection of the can.

Abstract: Encription apparatus for restricting distribution of private (e.g., premium) video programs propagated by a CATV cable network, radiation or the like employs picture carrier isolating, phase shifting and linear combining structure for rendering the transmitted video information unrecoverable by conventional television receivers. Authorized receiving stations are provided with inversely functioning electronics which reconstitute the prescribed video amplitude modulation format to permit signal reception. Similar audio program modification and correction structure permits encription and selective reception of the sound portion of the distributed programming.

Abstract: A continuous electrically conductive ring is applied to the top of a lid which is used for covering a container opening. The lid is then placed on the opening of the container and current is placed in the conductive ring. The current in the conductive ring causes heat which causes the lid material to fuse to the surface contacts of the container opening. The current is then removed and the material is allowed to cool creating a seal between the lid and the container.
