  • Patent number: 11392279
    Abstract: Systems, methods and devices for surfacing web content in an operating system shell construct are provided. A taskbar web content element size may be selected based on an amount of free space in a taskbar. First and second scored web content may be received, wherein the web content is scored based at least on the web content's relevance score to a first user account. A taskbar web content topical display category corresponding to the first web content may be selected based on the first web content having a higher score than the second web content. A web content element of the selected size and topical display category may be caused to be surfaced in the taskbar. A selection of the surfaced web content element may be received and a subset of the first web content form the first source may be caused to be surfaced in a web content pane.

  • Patent number: 8752711
    Abstract: This invention concerns a system for sorting elongated random width wood boards and preparing board rows having a row width within a predetermined width range. The system comprises a main longitudinal surface, a conveyor for conveying the boards on the main surface, a width detector, and accumulating compartments located one after the other under the main surface, controllable traps located on the main surface providing access to the accumulating compartments, controllable gates for retaining or releasing the boards accumulated therein and a controller. The controller selectively distributes each of the boards into the accumulating compartments, and controls the gates of the accumulating compartments to release the boards accumulated therein when the sum of the widths of the boards accumulated is within the predetermined width range.

  • Patent number: 4502189
    Abstract: A coupling for pipe or the like made up of a plurality of spaced generally hollow cylindrical bodies made of sheet material and each having their adjacent ends bent back on themselves forming a pocket along each edge, an outrigger bar extends through the pocket on one edge of each of the bodies and a short bar extends through the pocket on the outer edge of each body. The short bars are connected to the outrigger by means of bolts and a flexible liner is supported inside each of the bodies forming a gasket for surrounding a pipe extending through the bodies. In the second embodiment a basic difference is that the couplings are made up of clamps or outrigger clamps at two halves rather than in a single band.
