  • Patent number: 11174766
    Abstract: The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) (“dP”) without causing excessive backpressure in the air-oil separator.

  • Patent number: 10913023
    Abstract: A rotating separator has a housing preventing separated liquid carryover. A plenum between the annular rotating separating filter element and the housing sidewall has one or more flow path separating guides minimizing the flow of separated liquid to the outlet. The flow path guides may include one or more fins and/or swirl flow dampers and/or a configured surface.

  • Patent number: 10688426
    Abstract: A gas-liquid separator comprises a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. An impactor nozzle structure is supported by the housing and situated downstream of the inlet. The impactor nozzle structure receives the gas-liquid stream and accelerates the gas-liquid stream through an orifice that extends through the impactor nozzle structure. An impaction surface is supported by the housing and situated downstream of the orifice. The impaction surface receives the accelerated gas-liquid stream and causes separation of liquid particles from the gas-liquid stream so as to produce the gas stream, and a baffle situated downstream of the impaction surface modifies a flow of the gas stream so as to reduce carryover of liquid particles in the gas stream. A shroud tier an inertial impactor gas-liquid separator is disclosed. A method for separating liquid particles from a gas-liquid stream is disclosed.

  • Patent number: 10232301
    Abstract: A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.

  • Publication number: 20160350315
    Abstract: In order to facilitate access to pages in documents (such as slides in presentations and/or frames in videos), a system may create pointers specifying the pages in the documents, and may aggregate the pointers in an index. For example, the index may be aggregated based on keywords in content in the documents, metadata associated with the documents and/or presentation formats of the pages. Then, when the system receives a search query, the system may identify a match in the pointers in the index based on the search query and the keywords, the metadata and/or the presentation formats in the index. Next, the system may provide a pointer in the index based on the match. This pointer may allow a page in a document to be accessed without extracting or copying the page.

    Abstract: In order to facilitate access to pages in documents, a system may ingest pointers that specify the pages in the documents from hypertext documents on a network, and may aggregate the ingested pointers in an index. For example, the index may be aggregated based on keywords in content in the documents, metadata associated with the documents and/or presentation formats of the pages. Then, when the system receives a search query, the system may identify a match in the pointers in the index based on the search query and the keywords, the metadata and/or the presentation formats in the index. Next, the system may provide a link with a pointer in the index based on the match. When the system receives information specifying activation of the link, the system may access a page in a document associated with a hypertext document, without extracting or copying the page.
