  • Patent number: 11951453
    Abstract: Superficially porous particles are disclosed, each including a solid core and a layered porous shell. The layered porous shell includes a porous inner layer and at least one porous outer layer, a shell skeleton thickness greater than 1 nm, and constitutes from 10 vol % to 90 vol % of the plurality of superficially porous particles. The porous inner layer includes an inner layer thickness of less than 300 nm. The at least one porous outer layer includes a cumulative outer layer thickness ranging from 1 to 100 times the inner layer thickness, a predominately radial pore orientation, and an outer layer pore structure which is more organized than the inner layer pore structure. A layer-by-layer process for forming a plurality of superficially porous particles with layered structure is disclosed. A post-modification process for preparing a plurality of chromatographically enhanced superficially porous properties is also disclosed.

  • Patent number: 11927717
    Abstract: A method for history matching a reservoir model based on actual production data from the reservoir over time generates an ensemble of reservoir models using geological data representing petrophysical properties of a subterranean reservoir. Production data corresponding to a particular time instance is acquired from the subterranean reservoir. Normal score transformation is performed on the ensemble and on the acquired production data to transform respective original distributions into normal distributions. The generated ensemble is updated based on the transformed acquired production data using an ensemble Kalman filter (EnKF). The updated generated ensemble and the transformed acquired production data are transformed back to respective original distributions. Future reservoir behavior is predicted based on the updated ensemble.

  • Patent number: 11925759
    Abstract: A ballooning patient interface has a frame that supports a sealing member. The frame and/or the sealing member is secured to the head of a user with headgear, such as a strap. Various features of the sealing member improve comfort for the user in the nares of the users as well as on facial surfaces in contact with the sealing member.

  • Patent number: 11419348
    Abstract: A system for automatically cleaning and washing an ice cream machines includes a liquid container for storing raw materials; a freezing cylinder connected with the liquid container through a cleaning pathway; a water tank for storing rinse water to rinse the freezing cylinder and the cleaning pathway; a detergent tank for storing detergents to clean and wash the freezing cylinder and the cleaning pathway; a pump arranged on the cleaning pathway to selectively pump the raw material, the rinse water or the detergent; and a control panel adapted to control an on/off and cleaning.

  • Publication number: 20080096981
    Abstract: A novel TH2 associated gene that is induced by IL-9 has been identified and isolated, thereby providing a therapeutic target for IL-9 mediated diseases such as atopic allergy and asthma-related disorders. The invention also includes methods for the identification and use of small molecule inhibitors of this gene and its products to treat these disorders, methods for diagnosing susceptibility to, and assessing treatment of atopic allergy or asthma-related disorders by measuring the level of gene expression in biologic samples using antibody specific for this protein. The use of this protein as a therapeutic agent for the treatment of autoimmune diseases is also indicated.

  • Patent number: 4305105
    Abstract: A linear actuator for a magnetic disc drive has shortened magnetic flux lines totally confined within the actuator housing whereby the actuator can be placed in closer proximity to a disc and thus reduce the size of the disc drive package. The actuator includes a generally cylindrical housing with magnets attached to the inside surface of the housing. A cylindrical bobbin having a voice coil wound on its periphery is positioned within the housing and linearly movable therein with the voice coil in close proximity to the magnets. An annular magnetic flux transmission means is attached to one face of the housing and a flux transmission plate is attached to the opposite face of the housing with the flux transmission means providing magnetic flux paths and preventing flux leakage from the housing.
