  • Publication number: 20190266102
    Abstract: Systems, apparatuses, and methods for efficiently allocating data in a cache are described. In various embodiments, a processor decodes an indication in a software application identifying a temporal data set. The data set is flagged with a data set identifier (DSID) indicating temporal data to drop after consumption. When the data set is allocated in a cache, the data set is stored with a non-replaceable attribute to prevent a cache replacement policy from evicting the data set before it is dropped. A drop command with an indication of the DSID of the data set is later issued after the data set is read (consumed). A copy of the data set is not written back to the lower-level memory although the data set is removed from the cache. An interrupt is generated to notify firmware or other software of the completion of the drop command.

  • Patent number: 4576918
    Abstract: A method and apparatus for determining the composition and the concentration of biocidal gas and other gases contained in a reaction chamber during processing of material contained in the chamber and exposed to the treating gas. A valved pre-evacuated gas-sampling vessel is positioned in the reaction chamber and, thereafter, opened by remote control to receive a gas sample representative of the gaseous atmosphere present in the chamber. The sampling vessel is then closed, removed from the treatment chamber, and connected to apparatus for analyzing the gas in the vessel. The qualitative and quantitative composition of the treating gas is thus determined.

  • Patent number: 4378334
    Abstract: A method and control apparatus for the safe and effective ultimate disposal of spent biocidal gases such as alkylene oxides after their use in a reactor, including hopsital-type gaseous sterilizers, to reduce the concentration of viable organisms present as contaminants in articles treated in the reactor. The disposal is carried out in a manner to prevent air contaminating release of objectionable material into the atmosphere. The process includes the steps of pumping the biocidal gas from the reactor, delivering the gas to a combustion chamber fitted with a flue gas stack, and igniting and burning the gas in the combustion chamber in the presence of and aided by an added auxiliary combustible fuel augmented by a supply of air. Safety devices such as temperature controls and sensors, flame sensors, flash arrestors, and automatic shut off valves minimize potential hazards.

  • Patent number: 4301113
    Abstract: In the treatment of articles with a sterilant gas such as an alkylene oxide, and the circulation of the gas throughout a treatment chamber containing the articles to be treated, a gas circulating system completely devoid of electrical contacts, switches, electrical motors and other potentially dangerous electrical components which could cause explosive ignition of the sterilant gas. The circulation system includes a fluid-driven turbine-like impeller completely isolated from the sterilant gas, and drivingly coupled to a fan blade which serves to force the gas through conduits and to circulate and recycle the sterilant gas throughout the treatment chamber. In a second embodiment of the invention a magnetically coupled drive is used to actuate the sterilant-circulating fan.
