  • Patent number: 11117083
    Abstract: A method to form a laminar integral skin of a honeycomb structure is provided. The method includes extruding a ceramic precursor batch through a die with feedholes in entry side and slots in exit face of the die to form the honeycomb structure. In a region on the periphery of the die configured to form the cell matrix, a series of concentric slots around the matrix in the exit face of the die are configured to feed skin onto the matrix. Ring sections between concentric slots are angled away from the center and a mask is disposed on top of the periphery producing a channel for extruded skin to meet and bond to extruded matrix. Optionally, slots in the skin-forming ring sections enhance knitting between laminar skin layers. The die and honeycomb body having uniform integral skin are also provided.

  • Patent number: 11092120
    Abstract: An apparatus and a method are provided for an air filter configured to be mounted onto air inlets of turbochargers and superchargers. The air filter comprises a proximal base including an inlet receiver configured to receive an air inlet, a clamp to secure the air inlet within the inlet receiver, and a first opening aligned with a screw mechanism of the clamp. A filter medium fastened to the proximal base is configured to remove particulate matter and other contaminates from an incoming air stream. A distal end cap fastened to the filter medium comprises a second opening aligned with the first opening. A conduit within an interior cavity of the air filter is disposed between the first opening and the second opening, facilitating tightening and loosening the clamp by extending an appropriate tool through the interior cavity so as to engage the screw mechanism of the clamp.

  • Patent number: 11065571
    Abstract: Provided is a honeycomb filter, including: a pillar-shaped honeycomb substrate having an inflow end face and an outflow end face and including a porous partition wall surrounding a plurality of cells; and a plugging portion disposed at any one of ends of the cells at the inflow end face and at the outflow end face. In a cross section orthogonal to an extending direction of the cells, inflow cells have a pentagonal or a hexagonal shape, and outflow cells have a square shape. The cells are configured that the inflow cells surround one outflow cell and one side of an inflow cell and one side of an adjacent outflow cell are parallel to each other. The partition wall is configured that thickness of a first partition wall disposed between the inflow cells and the outflow cells is larger than thickness of a second partition wall disposed between the inflow cells.

  • Patent number: 11060456
    Abstract: A centrifugal deaerator for an air/oil mixture of a turbine engine includes: an annular housing arranged around a hollow shaft and having an outer annular wall and an inner annular wall; axial mixture inlets for the inflow of the air/oil mixture into annular housing; a pinion for rotating the annular housing, the pinion including a web that is securely connected to the hollow shaft and to the inner and outer annular walls; radial oil outlets in the outer wall; and oil-free air outlets in the inner wall. The axial mixture inlets and the radial oil outlets are axially arranged on either said of the web to prevent the axial mixture inlets from reintroducing oil evacuated by radial oil outlets into the annular housing.
