Abstract: Advertisements over a network, such as the Internet, by extracting an index file of suppliers of search result sets for a plurality of keywords and/or an index of ads to be placed. A keyword in a received query may be matched to the suppliers of related search result sets and/or the ads to be placed in the index file(s). The search results may be ranked based on various criteria such as yield, click through rates and history of dealings. Search result sets for the keywords from the matching suppliers and the ads to be placed may be combined to produce a search result set ranked in accordance with estimated yields for advertisements associated with each result in the search result set and delivered in response to the received query. The search results in the combined set may be reranked and/or repriced.

Abstract: An apparatus and method for reducing the circling upward movement of a product such as waste paper entrained in a carrier stream. The invention includes a product rake placed within a discharge chute to capture and direct product within the product flow. A further aspect of the invention includes a relief valve integrated into the discharge chute to alleviate pressure in the discharge chute and allow excess air to be relieved from the discharge chute to control the product flow.

Abstract: A process for removing the coating and any metals from polymeric substrates such as compact discs (CDs) and digital video discs (DVDs) by applying high shear conditions to fluidized particulates of the polymeric substrate optionally in the presence of an accelerant.

Abstract: The invention comprises a method and apparatus for recycling foamed polystyrene from municipal solid waste and more particularly, from fast food restaurant waste. A steady stream of waste is delivered to a flail mill for reducing particle size, a rotary trommel for eliminating undersized waste and a rotary air classifier for removing "heavy" waste from the stream. At this point, the waste stream comprises mostly paper and foamed polystyrene. The paper and foamed polystyrene are delivered to a water pulper which fiberizes the paper so that it can then be separated from the foamed polystyrene by passing it through a screen of selected mesh size to allow the water and paper pulp to pass through while retaining the foamed polystyrene.
