  • Publication number: 20190248099
    Abstract: The equipment panel includes a cellular core inserted between first and second skins. The method includes: assembling the first skin with the cellular core, the cellular core being arranged such that its cells extend perpendicular to the first skin; filling a peripheral zone of the cellular core with a resin; assembling the second skin with the cellular core; polymerizing the resin, thus securing the cellular core with the first and second skins; machining a contour of the panel, the contour being defined in a plane parallel to the first and/or second skins, and machined in the peripheral zone; and assembling a lateral skin on the edge of the panel with the machined contour.

  • Patent number: 10017193
    Abstract: The comfort device (10) includes a table (12) including a plate (22) and attachment unit (14, 16) including: a lateral fixed support (46), attached to a vertical wall (20), including a first connecting portion by sliding, an attachment member (52) secured to the plate (22), including a second connecting portion by sliding, mating the first, and unit retractable unit for blocking the attachment member on the lateral fixed support, active at the end of a predefined travel of the first connecting portion on the second connecting portion. These blocking units are movable between a blocking position in which the first and second connecting portions are secured to each other, and a release position in which the first and second connecting portions are free to move relatively to each other.

  • Patent number: 5295183
    Abstract: A congestion control system is provided which is an enhancement of the dynamic call routing system taught by Szybicki et al. in U.S. Pat. No. 4,284,852. The congestion control system includes two parts, a restrictive control and an expansive control. The restrictive control uses data collected by the network processor to provide a call gapping recommendation which is automatically updated each cycle (typically 10 seconds). The call gapping recommendation is used to restrict entry of calls to the network. The expansive control system uses a call compression factor to deflect tandem traffic from overloaded nodes. If direct traffic continues to increase, the restrictive control takes over from the expansive control.
