  • Patent number: 12179644
    Abstract: A convertible child restraint includes a lower base to contact a vehicle seat, a seat shell to support a child, and a mid base between the lower base and the seat shell to facilitate recline and rotational adjustment of the seat shell relative to the lower base. The child restraint may be used as a rear-facing car seat, a forward-facing car seat, and a belt positioning booster seat. For the rear-facing car seat configuration, a belt is installed along a rear-facing belt path that passes through the child restraint. The portion of the belt in the child restraint is accessed via a belt access panel when the seat shell is at a rear-facing position. Additionally, the child restraint includes a rotation lockout that allows the seat shell to be rotated from a rear-facing position to a side-facing position, but not a forward-facing position when using the rear-facing configuration.

  • Patent number: 12049429
    Abstract: A honeycomb body having a cutout, an assembly including the honeycomb body, and a method of manufacturing. The method includes forming the honeycomb body having a matrix of intersecting walls that define a plurality of cells and channels extending longitudinally through the honeycomb body. A subset of the channels are plugged to create a plurality of plugged cells in a reinforcement region of the honeycomb body. Material is removed from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body.

  • Publication number: 20230398716
    Abstract: An extrusion die (16) including a plurality of pins (38) having side surfaces defining an intersecting array of slots (30) extending axially into the die (16) from a discharge face (34) of the die (16). A plurality of feedholes (28) extend axially from an inlet face (32) of the die (16) opposite to the discharge face (34). The feedholes (28) connect with the slots (30) at intersections (35) within the die (16) to create a flow path from the inlet face (32) to the discharge face (34). A first coating (42) is on at least a portion of the feedholes (28) in a first zone (46) extending over a first axial length of the flow path. A second coating (44) that is different than the first coating (42) is on at least a portion of the side surfaces (37) of the pins (38) in a second zone (48) extending over a second axial length of the flow path. Methods of fabricating an extrusion die (16) and manufacturing a ceramic article (100), such as a honeycomb body, are also disclosed.

  • Patent number: 10328627
    Abstract: An extrusion apparatus including a die and a mask are provided such that no slots feed directly into the longitudinal skin forming gap between the mask and the die. In a method of forming a die adapted to improve skin uniformity of extruded cellular ceramic substrates a slotted block of die material is provided including central slots adapted to form a cellular matrix of the substrate and peripheral slots located outwardly of the central slots designed to be covered by a skin former mask and adapted to extrude peripheral batch material. An arcuate skin former is cut corresponding to a target shrinkage so as to intersect the slotted block such that skin flow from tangent slots at 90 degree positions of the die is limited to the peripheral batch material.

  • Patent number: 8924545
    Abstract: Embodiments are directed to creating a persona from observed characteristics of content and to sharing a network persona derived from observed characteristics of content. In one scenario, a computer system observes one set of properties for a first portion of content on a network. The first portion of content is from a first account. The computer system also observes a different set of properties for a second portion of content on the network, where the second portion of content is from a second account. The computer system then correlates an association between the first account and the second account as part of a network persona that is based on the first properties and one or more corresponding properties from the second portion of content.
