System and method for enabling multi-element bidding for influencinga position on a search result list generated by a computer network search engine
InactiveUS20030033292A1Easily predict position of their web siteIncrease exposureFinanceAdvertisementsWeb siteResult list
A system and method for enabling information providers using a computer network such as the Internet to influence a position for a search listing within a search result list generated by an Internet search engine. A database stores accounts for the network information providers. Each account contains contact and billing information for a network information provider. In addition, each account contains at least one search listing having at least three components: a description, a search term comprising one or more keywords, and a bid amount. The network information provider may add, delete, or modify a search listing after authenticated login. A search term relevant to the content of the web site or other information source to be listed is first selected. A search listing includes the search term and a description. A bidding process occurs when the network information provider enters a new bid amount for a search listing. The system and method then compares the bid amount with all other bid amounts for the same search term, and generates a rank value for all search listings having that search term. The rank value determines where the listing will appear on the search results list page that is generated in response to a query of the search term by a searcher.

Microwave drying of hides under vacuum in tanning equipment
InactiveUS6092301AHigh market valueQuality improvementDrying solid materials with heatDrying solid materials without heatWater contentSolvent
By providing a hide processor or tanning drum with appropriate equipment for applying vacuum and microwave energy concurrently, these tanning machines become a versatile means of drying to yield dry hides that contain no salt yet store better than salted hides. In this novel process, fresh hides are loaded into the tanning machine where they are washed, demanured and then dried in situ under vacuum with concomitant application of microwave energy. Because the dried hides thus obtained are soft and pliable, they can be mechanically fleshed or shaved to remove the subcutaneous tissues rich in collagen and fat. Alternatively, the hides may be first dried in the tanning machine to below 35% moisture content and degreased using a solvent such as hexane. The solvent remaining in the hides after decantation of the unabsorbed liquid is vaporized at low temperature using vacuum and microwave energy. The hides are then dried in situ to the desired final moisture content. By shaving off the subcutaneous tissues of these hides a dry, fat-free, valuable undenatured collagen product is obtained. If the hides are unhaired before drying, they may be shaved and then accurately split. The process is also suitable for removing hair and fat from hide trimmings to obtain a valuable undenatured collagen product and fat. Furthermore, it can be used to remove fat from connective tissues and other animal offal containing no hair yielding a dry undenatured collagen product.
