Abstract: A point of sale audio-visual advertising system is disclosed which has a central station and a plurality of outstations. The central station is generally located in a shop attached to service or filling stations which sell petroleum products such as gasoline, while the outstations are located at self-service pumps located on the driveway of the service station. The system provides audio-visual advertising material to the purchaser while the tank filling operation is in progress and immediately prior to his entry into the shop area.

Abstract: A transportation container (68,44) for transporting items or enclosures (72) requiring electrostatic protection includes a box (44) lined with electrically conductive bubble layer material (58) which protrudes from open seams (66) and which is also electrically accessible through an aperture (28) in registration with an opening (42) when the box (44) is contained within the sleeve (68). The accessibility of the electrically conducting bubble sheet material (58) allows for either deliberate discharge to ground potential of the bubble material (58) via the aperture (28) or provides ample opportunity for accidental discharge to ground by virtue of protrusion of the bubble material (58) through the open seams (66). The bubbles of the material (58) distort and burst to accommodate a range of enclosures from very small to quite large by virtue of the fact that the tips of the bubbles (62) just touch without compression when the box (44) is closed.
