摘要： A process for the manufacture of grinding elements composed of aluminum oxide, the process including the steps of (a) mixing aluminum oxide with from 0.5 to 2.5 Wt. % of an organic binder based on the aluminum oxide to provide a mixture; (b) granulating the mixture to form a granulate; (c) molding the granulate into molded pieces having grinding element shapes by applying pressure thereto; and (d) firing the molded pieces at a temperature ranging from 1500.degree. C. to 1850.degree. C. in a vertical kiln to produce grinding elements comprised of aluminum oxide.

摘要： Methods, systems, and apparatus for improved trading of financial interests via a computer network are disclosed. Improvements include crossing or commingling of auction and non-auction transaction proposals; disclosure of high bids and of identify of high bidders and offerors during the auction process; presentation of reference benchmark prices and benchmark-derived price references; immediate rescission of multiple proposed transactions in case of emergency; time-limited passwords; assignment of user access level classes; keyword tagging or identification of offers or bids; the use of multiple data sets or trading channels to enable separation of accounting and to accommodate training and familiarization efforts; enabling the creation of data sets in outside programs and subsequent and optionally repeated uploading or importation of data to the auction system; and staging of transactions for supervisory review. The invention includes methods and processes as well as suitable computer programs and data processing systems.
