  • Patent number: 11979635
    Abstract: Systems and methods are described herein for recommending content restrictions to a user based on chatter in a social network of the user. The system analyzes chatter in the social network to identify a correlation between what is posted by users and the content that the users are posting about. The system stores a mapping between chatter and expected attributes of the content referenced by the chatter. The system will determine whether to block the content when an expected attribute is associated with a content restriction.

  • Patent number: 10787936
    Abstract: An expander of the piston (2) and cylinder (3) type is inverted from normal orientation, with the crankshaft (4) upper most and the cylinder “head” (5) lower most. The cylinder head has a pair of liquid injectors (6, 7) oriented for respective liquids pentane and glycerine to be injected as mists into contact with each other at the bottom of the cylinder. The pentane is vaporised by transfer of latent heat to it from the glycerine. Respective injector valves (9, 10) from high pressure rails (11, 12) fed by pumps (14, 15) are provided. An exhaust valve (16) is opened by a cam (17) driven at crankshaft speed by a chain drive.

  • Patent number: 9683581
    Abstract: A stator assembly for a rotary machine having a rotor arranged to rotate about an axis in use. The stator assembly has a circumferential support member or casing arranged about said axis and a plurality of elements extending in a substantially radial direction from the support. The elements have a platform at an end thereof for engagement within the support, wherein the elements each comprise a hollow internal cavity having an opening through the platform at the end of the element, wherein said internal cavity is filled with a vibration damping material. The elements may be filled vanes in a gas turbine engine compressor. The platforms may also be filled with the vibration damping material.

  • Publication number: 20100191544
    Abstract: An author can create a protocol for providing user health coaching. The protocol is based on attributes and configures a health coaching service to be provided for a user. The author can use the attributes to report user health status, set user health goals, and evaluate expressions related to the user's health. The user health status can be reported based on author-created ranges that contain a user health attribute value. User health goals with respect to an attribute can be set over time for a user (or group of users) by the author. Expressions related to the user's health can be created by the author from sets of attributes and operators and executed as rules.

  • Publication number: 20020132547
    Abstract: A nonwoven fabric/film laminate material is particularly suited for use as a “housewrap”, or in like building construction applications. The laminate material comprises a spunbond polypropylene nonwoven fabric, and a breathable, polymeric film which is extrusion-coated onto the nonwoven fabric layer. Both the fabric layer and extrusion-coating can be formed in a cost-effective manner on conventionally available processing equipment. By appropriate selection of the nonwoven fabric layer and film properties, the present laminate material acts as an effective barrier to liquid water and air infiltration, while providing desirable permeability to water vapor.
