Abstract: 1430832 Electric cables BBC BROWN BOVERI & CO Ltd 14 June 1973 [16 June 1972] 28344/73 Heading H1A Over an insulating layer 2, surrounding a high voltage conductor core 1, there is an anticorona screening layer 3<SP>1</SP>, composed of a semiconductive tape material which initially is wound into place in a pre-stretched condition, and subsequently, by the application of heat, is caused to contract in the lengthwise direction of the tape, though not in its transverse direction. This tape may be of woven fibrous cloth, wherein the warp fibres may consist of polyester or organic polymeric material, which, having been stretched immediately upon leaving the extrusion die, can later become contracted when heated, and the weft fibres may either be of a similar material which has already been stabilized by heating, or of an inorganic substance such as glass or asbestos. Such fibrous tapes are rendered conductive by impregnation with a volatilizable liquid carrying conductive particles, e.g. graphite. The tape may alternatively be a foil strip which has been prestretched in a cold state, in its longitudinal direction, subject to contraction later when heated, and may be composed of polymeric carbon fluoride, polyvinylidene fluoride, or polyester, with the incorporation of a conductive filler, e.g. graphite, soot, lampblack or carbon black. The inner face of a foil tape may be etched to facilitate use of an adhesive, for bonding it to the layer below. Layer 2 may be composed of glass fibre and mica insulation, of known types. In an electrical machine embodiment, the conductors 1 are inserted into slots of a laminated ferrous rotor 5, in which contraction of the pre-stretched tape 3<SP>1</SP> may take place when the assembly is dried by heating, prior to overall resin impregnation.

Class 3(i) [Also in Group XV] Two turntables 4, 5 are rotatably mounted in a container.1, each turntable having a permanent magnet at or closely adjacent its axis of rotation and at least one turntable having one or more magnets adjacent its periphery, the container having a screen 2, forming or applied to a face of the container, which serves as a support or background for one or more devices made of magnetic material or having inserts consisting of magnets or magnetic material whereby when the turntables are rotated the device or devices are actuated. The turntable 4 which has a plurality of permanent magnets around its peripery and one at its centre is driven by an electric motor 6 and drives by means of a belt 8, the turntable 5 which is smaller in diameter and which has one magnet at its centre. When the container is positioned horizontally a detachable tray 17 is positioned over the screen 2 and supports objects which may be moved bodily by the magnetic fields from the turntables, or parts of which may be moved, e.g., as shown the head 21 and tail 22 of a model tortoise which are pivotally mounted and connected together and swing from side to side when a magnet or magnetic insert 24 in the head is moved by the field from the turntable 4. Heavy objects may be supported for rotation on a platform which has a central pivot and peripheral inserts of magnetic material and is placed on the tray 17 or screen 2 so as to be rotated by the field from the turntable 4. The central pivot projects further than the magnetic inserts so that the platform is in a semi-floating position. When the casing is positioned so that the screen 2 is vertical, the display object may be pivoted to a detachable panel so that it is moved in pendulum fashion by the magnetic fields: a spring may be used to assist the movement. An object of suitable weight may be entirely supported and moved by the magnetic field and its travel may be arranged to bridge two contacts on the panel to complete the circuit for an electric lamp which may thereby be caused to flash periodically. Movement of the devices may be made irregular by roughening the surface of the tray, screen or panel, at selected places so as to slow down the device at such positions.
