Abstract: An electrical cable may include: at least two first members extending along a length of the electrical cable, each of the first members including a conducting element and an insulating layer radially external to the conducting element; at least two second members extending along the length of the electrical cable, each of the second members including a strength element and a conductive layer radially external to the strength element; and/or the first and second members being stranded around and in contact with a cradle extending along the length of the electrical cable. The cradle may be made of polymeric material having a tensile modulus greater than or equal to 1 GPa and a Vicat softening temperature greater than or equal to 125° C.

Abstract: The present disclosure relates to an impact resistant, multipolar power cable (10) comprising, a plurality of cores (1), each core (1) comprising at least one conductive element (3) and an electrical insulating layer (5) in a position radially external to the at least one conductive element (3). The cores (1) are stranded together so as to form an assembled element providing a plurality of interstitial zones (2). An expanded polymeric filler (6) fills the interstitial zones (2) between the plurality of cores (1). An expanded impact resistant layer (7) is in a position radially external to the expanded polymeric filler (6) and comprises a polymer that differs from the expanded polymeric filler (6).

Abstract: An electric power cable contains a core and a jacket forming the exterior of the cable. The jacket is formed by extruding a first layer and a second layer over a plurality of concentric neutral elements, substantially encapsulating these elements. At least the first layer is an expanded polymeric material, by having its density reduced through the use of a foaming agent during extrusion. The second layer, which may also be expanded, is extruded around the first layer. The expanded polymeric material makes stripping the jacket easier, minimizes indentations in the cable's insulation layers, lightens the cable, and increases the cable's flexibility.

Abstract: An apparatus (100) and method cleans a batch of pellets or granules prior to use in an extrusion process. Loose contaminants having material characteristics that are undersired for the extruded product are first removed (110) from the batch using a deduster. The deduster may also remove uncontaminated fines and fluff from the batch. Pellets that are defective or otherwise undersired for the extrusion process as well as other loose particle contaminants can then be efficiently detected and removed (120) without the risks of fines clogging the apparatus or shielding the detection process. Magnets may help remove (130) particulates of ferrous material before or after the removal (120) of defective pellets. The resulting batch of pellets helps to produce extruded materials of higher quality, such as insulation material in electrical cables.

Abstract: A method of interacting between a display system and a user device is described in which a number of images are displayed by the display system. A user captures one of the images using a camera on the user device and sends the captured image over a wireless link to the display system. Upon receipt, the display system determines the identity of the sending user device and analyses the received image, and if the image matches one of those displayed, the system sends any data associated with the displayed image to the user device over the wireless link. A user may also upload data to form a media package over the wireless link.

Abstract: An electrical power cable with a foamed, compressible, semiconductive insulation shield which serves as both a cushioning layer and an electrical shield.

Abstract: A device for feeding a granular material from an upstream source to a downstream location such as a mobile container. The device comprising a conduit for receiving a flow of said granular material and which has an outlet for delivering granular material to said location. Then device further comprises a delivery system for delivering a stream of gas to the conduit to entrain and accelerate at least a portion of the granular material flowing therethrough, and an apparatus for directing the gas stream so that granular material is propelled from the outlet in a plurality of directions.
