Abstract: Process steps are provided for electronically sending promotional and advertising materials based upon consumer preferences by providing a unique identifier to a consumer's electronic mail address and sending electronic mail to the consumer, wherein the electronic mail includes a plurality of embedded Internet web sites. Thereafter, the consumer accesses the plurality of embedded Internet web sites in response to the sent electronic mail, and consumer movement within the plurality of accessed embedded Internet web sites is tracked. Promotional material can then be sent to the consumer based upon the tracked consumer movement within the embedded Internet web sites. Process steps are also provided to track consumer movement without the consumer's electronic mail address, if the consumer makes a purchase with a credit card while at a seller's web site. The IP address is linked to the credit card to track consumer movement within the web site.

Abstract: An improvement in efficiency of marine type oil spill clean up is achieved by using slideable fastners and support legs extending from a floatable unit to hold a skimmer unit in a relatively fixed horizontal position while using retractable cables with a hydraulic tensioning means to maintain the skimmer in a nearly constant relationship to the wave surfaces.
