  • Publication number: 20030225948
    Abstract: Provided are a method, system, and program for increasing processor utilization. A list of work is divided for processing among a plurality of processes, wherein a process is allocated a part of the list of work to process, and the processes execute in parallel. If a process completes the list of work allocated to the process then the process is made available on an available process queue. Before a process performs any work, the process reads the available process queue and determines if any process is available to share the work. If so, the work is split up between the examining process and the available process. In one implementation, the work involves scanning a cache and if necessary destage data.

  • Patent number: 6615318
    Abstract: In a cache management system multiple cache lists are utilized, where each entry in a list names at least one corresponding data item in cache. A cache manager always demotes cache list entries from a “current removal list” (and demotes or destages the corresponding data items from cache) until that list is exhausted and another list rotates into the function of current removal list. A prescribed order is established for rotating the role of current removal list. In response to prescribed activities of data items in cache, new cache list entries are added nearer or farther from the current removal list according to the prescribed order and the data items' priorities.

  • Publication number: 20030105928
    Abstract: Provided is a method, system, and program for destaging data from a first computer readable medium to a second computer readable medium. A list of entries indicating data blocks in the first computer readable medium is scanned. For each entry scanned, a determination is made as to whether the data block indicated in the scanned entry satisfies a criteria. If the data block indicated in the scanned entry satisfies the criteria, then a destage operation is called to destage the data block in the scanned entry from the first computer readable medium to the second computer readable medium. If the called destage operation is not initiated, then the scanned entry is removed from the cache list. The removed scanned entry is added to one destage wait list. During one destage operation, data blocks indicated in entries in the destage wait list are destaged.

  • Publication number: 20020162348
    Abstract: Heat pump equipment comprising at least three heat exchangers, one of which is intended to be located in an enclosed region and the other two of which are intended to be located outside the enclosed region. Each heat exchanger has a delta connection end connected in heat-exchange fluid communication with a delta arrangement. The delta connection end of each heat exchanger is connected to both of the delta connection ends of the other two heat exchangers via the delta arrangement. There are three fluid-expansion devices, one between the two connections of each pair of adjacent connections of the heat exchangers to the delta arrangement.

  • Patent number: 6276158
    Abstract: Heat exchange equipment comprising a compressor which is connected to an indoor heat exchanger and also to two outdoor heat exchangers, and flow-direction changing means to change the direction of flow in the heat exchangers whereby each of the outdoor heat exchangers can be defrosted whilst the other continues to remove heat from its surroundings. Pressure lowering means are provided between the two outdoor heat exchangers.

  • Patent number: 6186335
    Abstract: A improved process for beneficiating kaolin clays to remove discoloring impurities is disclosed. The beneficiation of kaolin clay is improved by fractionating a kaolin clay starting material into a lower brightness first fraction having a majority of the discoloring impurities and a higher brightness second fraction with less impurities. The first fraction is then beneficiated (such as by flotation, selection flocculation, high intensity magnetic separation and/or leaching) to produce a kaolin clay product with improved optical properties. The first and second fractions may be combined to produce a product with improved optical properties.

  • Patent number: 6041939
    Abstract: A process which uses selective flocculation with hydroxamates for the beneficiation of mixtures of mineral particles (such as kaolin clays). The increased selectivity of hydroxamates for certain mineral phases within kaolin clays and other mixtures of mineral particles improves the process over selective flocculation processes utilizing other activators.

  • Patent number: 5593490
    Abstract: A kaolin clay slurry having a reduced viscosity is manufactured by a process which comprises the sequential steps of mechanically working an undispersed crude kaolin clay material having a solids content of at least about 65 percent, by weight, under conditions which insure that the kaolin clay material will be subjected to an energy level of at least 10 horsepower-hours per ton of dry kaolin clay material and then subjecting the mechanically worked kaolin clay material to centrifugation to substantially remove any particles having a diameter less than about 0.2 microns.

  • Patent number: 4078178
    Abstract: A dynamic background subtraction circuit is disclosed which improves the display resolution of radiation energy spectra, such as X-ray energy spectra in an X-ray energy spectrometer. In this circuit, the number of radiation events (counts) occurring at a reference or background energy level is subtracted from the number of radiation events (counts) occurring at a second energy level under study. The output of this circuit is a real-time (dynamic) approximation of the count rate at the energy level under study, but with resolution improved by subtraction of the background counts.
