  • Publication number: 20230024656
    Abstract: A method of delivering a media stream in a network having first and second media servers each capable of delivering segmented media content to a requesting media client. The network provides for HTTP-based delivery of segmented media, and the media client is supported on a client-side device. The method begins by associating the media client with the first media server. As the first server receives from the media client request for media content segments, request times for a given number of the most-recent segments requested are used to generate a prediction, by the first server, of when the media client has transitioned from a start-up or buffering state, to a steady state. In response to a new segment request being received, and upon the first server predicting that the media client has completed a transition to steady state, the new segment request is redirected to the second media server.

  • Publication number: 20210006618
    Abstract: A plurality of WiFi-enabled devices that are physically proximate to one another form an ad hoc mesh network, which is associated with an overlay network, such as a content delivery network. A typical WiFi device is a WiFi router that comprises addressable data storage, together with control software operative to configure the device seamlessly into the WiFi mesh network formed by the device and one or more physically-proximate devices. The addressable data storage across multiple such devices comprises a distributed or “mesh-assisted” cache that is managed by the overly network. The WiFi mesh network thus provides bandwidth that is leveraged by the overlay network to provide distribution of content, e.g., content that has been off-loaded for delivery (by content providers) to the CDN. Other devices that may be leveraged include set-top boxes and IPTV devices.

  • Patent number: 5033926
    Abstract: Screens for limiting heat losses from heated material, e.g. bars and slabs in rolling mills. Screens are provided in the form of strings of heat insulating bodies composed of metal shells containing insulating material. These screens may form curtains and/or covers for the hot material. Containing chambers for the hot material may be provided with such strings of elements and the chambers may also comprise structure for limiting heat conduction losses through the material supports therein. The screens may be collapsed over the hot material thereby completely surrounding and insulating the material from loss of heat. A displaceable chamber installation may also be provided for limiting heat loss when holding and transferring hot material between processing stages.

  • Patent number: 4785654
    Abstract: To protect a heat shield arrangement over a hot-rolling mill, at the entry end of the table contact members of large mass are suspended over the path of the hot material to form a height barrier for distorted material. The members are suspended displaceably from bars on a cantilevered support that leaves one side of the table open for the removal of scrapped material. The bars pass through contoured apertures in the members which permit the members to move in forwards and upwards so that when struck by the material they can lift and can also yield to the frictional force of the material travelling under them. The loading on the cantilevered support is thereby reduced. Reduction in peak loadings also result from mounting the members on an upwardly pivotable cantilever frame and by damping the return movements of the members and/or the frame.

  • Patent number: 4719779
    Abstract: A heat shield arrangement for a hot-rolling mill has thin-walled heat insulating panels above below and at the sides of a hot material path through the mill. The upper and/or side panels are adjustable in position to reduce the free space around the material on said path and so improve the view factor. The upper panels are suspended from carrier frames which can be raised to lift the panels clear. With the frames lowered, the upper panels are adjustable between a raised ambush position and a fully lowered operative position. Lowering the panels from the ambush position can be triggered by sensing the presence of the material so that the panels become fully effective as a strip of hot material begins to pass under them but are held sufficiently high before threading to avoid damage from a hot strip with a distorted leading edge.

  • Patent number: 4499746
    Abstract: A heat shield arrangement for strip material employs insulating panels of thin-walled composite construction. The panels include an upper series displaceable upwardly by power actuation means to avoid damage by buckled or lifting material. Protective members projecting below the upper panels are associated with sensing means to actuate the raising of the upper panels and can have a limited displacement before the raising of the upper panels is actuated. The power actuation means can themselves act on the sensing means to determine the minimum force from the material that causes raising of said panels. Control means displace the panels in response to the sensed transverse temperature profile to maintain the profile more uniform and some of the panels may have heating means for this purpose.

  • Patent number: 4452587
    Abstract: A composite thermal insulation panel for a metal processing installation has a thin-walled casing providing a cover plate or membrane that will be heated quickly to near the temperature of an adjacent hot metal slab or strip being processed. To allow substantial freedom for movement relative to adjoining regions of the casing due to thermal expansion caused by the large temperature changes, retaining elements of the casing that locate the membrane transversely to its extent but permit relative movement in its own plane, and/or the membrane may have surfaces that slope to a central region to accommodate relative thermal expansion by flexure. Panels below the material path may have membrane surfaces that slope downwards to an escape aperture for scale dropping from the hot metal. Panels above the material path may have apertures aligning with the lower panel apertures for temperature sensors that detect the passage of hot material between the panels.

  • Patent number: 4449575
    Abstract: A heat exchanger for high temperature operation has a ceramic-walled chamber traversed by ceramic tubes and is capable of use inter alia in fluidised bed applications. The tubes are arranged in series of successive banks and to give a compact arrangement the successive banks of tubes at different levels are disposed transversely to each other. The tubes may have internal and external reinforcing means to allow them to withstand the loads imposed by the fluidised bed and generally to allow longer tubes to be used in ceramic constructions. The internal reinforcing means may also provide restrictions that in fluidised bed applications can function to minimise the effects of tube wall fracture by reducing carry-over of bed particles seeping into the tubes. For improved end sealing, means can be provided to hold resilient ceramic seals compressed against the tube ends while permitting axial thermal movement of the tubes.

  • Patent number: 4343168
    Abstract: A heat shield arrangement for strip material employs insulating panels of thin-walled composite construction. The panels include an upper series displaceable upwardly by power actuation means to avoid damage by buckled or lifting material. Protective members projecting below the upper panels are associated with pressure sensors to actuate the raising of the upper panels and can have a limited displacement before the raising of the upper panels is actuated. The power actuators can themselves act on the sensors to determine the minimum force from the material that causes raising of the panels. A control device displaces the panels in response to the sensed transverse temperature profile to maintain the profile more uniform and some of the panels may have heaters for this purpose.
