  • Publication number: 20190084253
    Abstract: An extruded thermoplastic product having a surface abrasive to insects. The extruded product is formed from a dry powder composition being comprised of a thermoplastic polymer, a plurality of pelletized diatomaceous earth, and a plurality of expandable microballoons. The composition is mixed and heated in an extrusion machine before being forced into a die of selected profile. Cooling the material immediately after being removed from the die allows the diatomaceous earth to remain at the surface of the material. The material with the surface abrasive to insects is used is used as a component in a product, such as conventional weatherization products, for placement in a building opening that insects use as ingress to the building. Products contemplated for use with the extrusion include door sweeps, door and window seals, and thresholds.

  • Publication number: 20180280657
    Abstract: A lamp for generating flickering at a selectable frequency corresponding to a desired human brainwave state comprises a base supporting a light source, a shade having a plurality of regularly circumferentially spaced apertures defined therein and a drive mechanism for rotating the shade about the light source. At least one speed control is coupled to the drive mechanism for controlling the rotational speed of the shade. Rotation of the shade while the light source is emitting light produces flickering for an observer looking at the lamp from a fixed position, and the speed control can be used to select a rotational speed of the shade to produce flickering at a frequency corresponding to a pre-selected human brainwave state.

  • Publication number: 20180266275
    Abstract: A housing for retention of the outer race of a bearing of a gas turbine engine includes an arrangement of spring fingers that yields a lightweight housing capable of withstanding very high radial loads combined with very high torsional windup and axial thrust load. Controlled circumferential gaps on both sides of each spring finger limit the deflection and self-arrest the distortion of the housing. The spring fingers define at least one side edge that extends at an angle relative to the axial direction. An axial gap is created on the aft end by a portion of the spring finger beam structure that opposes an axial face of the housing and limits the axial distortion. A radial gap created between interface hardware of the housing and the inner retention housing also acts to retain the spring finger housing under load in a radial direction.
