Abstract: A high power resistor grid assembly formed of a plurality of stainless steel resistor U-shaped elements arranged in a substantially parallel relationship welded together in a continuous path. Each element comprising a slotted rectangular sheet in a U-shape having elongated curved embossments to prevent warpage of the element upon heating. Each U-shaped element has alternately a right and left leg offset to permit end to end attachments of elements while maintaining uniform spacing between the elements. The elements are supported by pairs of double insulated members which are affixed to the top and bottom of a frame with a floating end to permit expansion of the assembly upon heating and contraction upon cooling.

Abstract: The present invention relates to a system for assembling a network of presentations comprising still video images with associated audio messages. The video images and audio messages are first recorded on separate recording mediums and then combines as a video/audio presentation network recorded on a video disc. The video disc can then be incorporated as part of the data base of an interactive communication system which transmits the presentations to subscriber's of the system.

Abstract: An electronic store is designed in the form a video/audio presentation network stored on a medium from which it can be retrieved by subscriber's to an interactive communication system. The presentations in the network comprise still picture images viewed by the subscriber with accompanying audio. These presentations, for example, can depict the offering of products or services to subscribers.
