  • Publication number: 20160171372
    Abstract: Embodiments are directed towards a method and a computer server for receiving assertions, wherein an assertion can have a functional property such that for a given subject and a given property the object has a single value at any time, maintaining a knowledge base that includes a history table that stores previously received assertions, the method comprising selecting an assertion for processing, generating an assertion tuple that corresponds to the selected assertion, determining that the property of the selected assertion is functional; and writing the assertion tuple to the history table.

  • Patent number: 8943017
    Abstract: Embodiments are directed towards a method and a computer server for receiving assertions, wherein an assertion can have a functional property such that for a given subject and a given property the object has a single value at any time, maintaining a knowledge base that includes (1) a history table that stores previously received assertions, and (2) a snapshot table that stores currently valid assertions, maintaining a snapshot cache in memory that stores a subset of the assertions in the snapshot table, initiating a processing cycle, selecting an assertion for processing, generating an assertion tuple that corresponds to the selected assertion, determining that the property of the selected assertion is functional, writing a retraction tuple to the history table, writing the assertion tuple to the snapshot table; and writing the assertion tuple to the history table.

  • Patent number: 5027887
    Abstract: A system for delivering fluid lubricant to the surfaces of the sidewalls of a mold of a continuous casting machine is provided by a continuously surrounding lubrication gap connecting a manifold to the sides of the casting mold. The lubricating gap has substantially the same resistance to flow between the manifold and the adjacent side of the mold cavity of the mold around the complete perimeter of the mold cavity and has significantly higher resistance to flow of lubricant from the manifold to the mold cavity than the resistance to flow around the manifold and into the gap, whereby the lubricant is uniformly distributed to all the walls of the mold. Preferably the gap will be divided into discrete passages, one for each side of the mold cavity by means of a shaped spacer which also defines the height of the gap and thereby the height of each of the passages. Each passage will normally be of substantially constant width corresponding substantially to the length of the adjacent side of the mold cavity.
