  • Patent number: 11933528
    Abstract: Methods and systems provided for determining a phase state and/or for determining a degree of subcooling in a fluid. An exemplary method for operating a refrigeration cycle includes flowing a refrigerant through a metering device and calculating a pressure differential of the refrigerant across the metering device. Further, the method includes determining whether the refrigerant is a saturated liquid based on the pressure differential. The method includes, when the refrigerant is not a saturated liquid, cooling the refrigerant upstream of the metering device.

  • Publication number: 20230231879
    Abstract: In one embodiment, a similarity index is calculated from characteristics of a suspected phishing web page to a database of known phishing web pages. The characteristics derive from both HTML tags of the suspected phishing web page and a screenshot of the suspected phishing web page. With machine learning using the similarity index as an input, a probability is estimated that the suspected web page comprises a known phishing web page from the database of known phishing web pages. A known phishing web page is selected from one or more candidates known phishing web pages, based on having a highest probability.

  • Publication number: 20210099484
    Abstract: Systems and methods for detection of suspicious phishing webpages are provided. According to one embodiment, a client device captures an image pertaining to a webpage attempted to be accessed via the client device and generates a fingerprint of the webpage based on application of a hash function to the captured image. For each phishing fingerprint within a phishing fingerprint database containing fingerprints associated with known phishing webpages, the client device determines a similarity measure between the generated fingerprint and the phishing fingerprint by comparing the generated fingerprint with the phishing fingerprint such that when the similarity measure meets a threshold, the client device identifies the webpage as potentially being a phishing webpage. The phishing fingerprint database periodically receives an update containing new fingerprints from an online security service.

  • Patent number: 7235201
    Abstract: A device to compact parts out of powder material including a top die and a bottom die movable with respect to each other from an open position to a closed position, at least one punch associated with each of said dies for relative movement between the die and associated punch, said bottom die and bottom punch movable to positions defining a cavity substantially within said top die for receiving powder therein, said bottom punch and said top and bottom dies being relatively movable to draw powder down into a portion of said cavity adjacent the bottom die that is formed due to said relative movement, said top and bottom punches being movable toward each other to compact the powder and form the part, said top and bottom dies being separable to eject the part. Relative movement of the top and bottom die and bottom punch may take place during filling of the cavity with powder.

  • Publication number: 20070048169
    Abstract: A method of producing parts from powdered metal having a first step of providing a powder, which is compressed at a pressure of 25 to 65 tsi to provide a green compact. The compact is then sintered at 2000° F. to 2400° F. for 20 to 60 minutes and cooled. After the compact has been cooled, the density of the compact is increased to greater than 7.4 g/cc. The compact is austenitized in an atmosphere of gas containing propane and a carbon potential of 0.8%. In one embodiment, the gas also contains ammonia. The compact is heated in the atmosphere at a temperature of 1600° F. for 40 minutes. Immediately following the heating, the compact is quenched in oil a temperature between 120° F. and 150° F. for 10 to 15 minutes. Lastly the compact is tempered at a temperature between 300° F. and 1000° F. for 30 to 90 minutes.

  • Publication number: 20060182648
    Abstract: A powder metal part is made by compaction at room temperature or an elevated temperature followed by sintering, a secondary densification, heat treating, and optional secondary operations. The particulate materials preferably include iron, 0-2.0 wt % copper, 0.15-0.9 wt % carbon, 0.5-2.0 wt % molybdenum, 0.5-4.5 wt % nickel, 0-4.0 wt % chromium, and 0-1.5 wt % silicon. At least one secondary densification is applied to the part after compaction and pre-sinter/sinters steps to achieve medium to high density. The secondary densification is part of a double-press double-sinter (DPDS) or is a mechanical working depending on the application requirements. The powder metal is heat treated by austempering or marquenching followed by tempering. A unique composite microstructure is achieved from austempering by controlling the powder chemistry and the holding time at an elevated temperature.

  • Patent number: 6997704
    Abstract: A method and apparatus for delubrification of parts. The method comprising the steps of moving the parts on the belt into a chamber of the furnace, heating the parts, igniting the unused combustible atmosphere above the parts, and allowing the atmosphere above the parts to escape through a vent in the chamber. The parts are heated uniformly by a heat source beneath the belt. The hot atmosphere is forced up through at least one plenum by blowers. The unused combustible atmosphere in the chamber above the parts on the belt is ignited using a burner and vented through the vent in the chamber.

  • Publication number: 20050163645
    Abstract: A method of producing parts from powdered metals is disclosed, comprising the following steps. A metallurgical powder is provided, consisting of iron, 0.3-1.0 weight percent carbon, 0-4 weight percent chromium, 0-3 weight percent copper, 0.5-1.5 weight percent molybdenum, 0.5-4.5 weight percent nickel, 0-1.0 weight percent manganese, and 0-1.5 weight percent silicon. Metal powders are made by atomization and mixing. The powder metal parts are made by compacting, pre-sintering, profile/form grinding, sinter furnace hardening, and secondary operations. Profile/form grinding generates profiles, which can not be formed by compaction tooling, such as undercut. The specific pre-sinter cycle makes parts strong enough for profile grinding with prolonged tool life. Powder metal parts made by this invention are also disclosed.

  • Publication number: 20050129563
    Abstract: A method of producing parts from powdered metal comprising the steps of providing a metallurgic powder comprising iron, 0-0.6 weight percent carbon, 0.5-5.0 weight percent silicon, 0.5-6.0 weight percent nickel, 0.5-1.5 weight percent molybdenum, 0-0.7 weight percent manganese, and 12-20 weight percent chromium, the weight percentages calculated based on the total weight of the powder. Secondly, the powders are compressed at a pressure of 35 to 65 tsi to provide a green compact. Then, the compact is heated in an atmosphere to a temperature of 2100° F. to 2400° F. for 20 to 90 minutes, such that the resulting microstructure of the compact is either single phase ferritic or dual phase ferritic and austenitic.

  • Publication number: 20050123432
    Abstract: A method of producing parts from powdered metal comprising the steps of providing a metallurgic powder, compressing the powder at a pressure of 25 to 65 tsi to provide a green compact with a density if 6.4 g/cc to 7.4 g/cc. The compact is then high temperature sintered at a temperature of 2100° F. to 2400° F. for 20 to 60 minutes or regularly sintered at a temperature of 1650° F. to 2400° F. for 20 to 80 minutes, held between 1000° F. to 1800° F. for 5 to 60 minutes, and then cooled to room temperature. Then, the compact is selectively densified to greater than 7.6 g/cc. The compact is sinter hardened to obtain a mainly Martensite microstructure. The compact can be directly high temperature sinter hardened if selective densification is not necessary. Material made by this method is also disclosed.
