摘要:
Induction heating of wires in a harness or wiring bundle generates heat to cause fusible blocking material to flow and block the spaces within the harness and to shrink a plastics sleeve around the blocked region. Either the blocking material or the sleeve (but not both) may also be inductively heatable.

Disclosed is a method for producing colloidal graphene dispersions comprising the steps of (i) dispersing graphite oxide in a dispersion medium to form a colloidal graphene oxide or multi-graphene oxide dispersion (ii) thermally reducing the graphene oxide or multi-graphene oxide in dispersion. Dependent on the method used for the preparation of the starting dispersion a graphene or a multi-graphene dispersion is obtained that can be further processed to multi-graphene with larger inter-planar distances than graphite. Such dispersions and multi-graphenes are for example suitable materials in the manufacturing of rechargeable lithium ion batteries.

[Problem] In some cases, it is difficult to uniformly apply a sealant when a waterproofing treatment is applied to aligned wires. [Solution] In a sealant applicator 1 for applying a waterproofing treatment to a wire assembly, a plurality of wires are aligned in a line according to their diameters in a holder 4 provided on a wire laying board 3. Positioning members 21 of a main unit 2 is fitted to the holder 4. A pair of nozzles 22 are opposed to each other at the opposite sides of the aligned wires, and is caused to discharge a specified amount of the sealant by a feeding mechanism 26 while being moved in a wire alignment direction by a moving mechanism 27 and being brought closer to the wires by a relatively moving mechanism 25. This enables a variation of clearances between the wires and the nozzles to be reduced and the sealant to be uniformly applied. [Effect] The waterproofing treatment for the wire assembly can be simplified and speeded up.

Apparatus and systems for applying filling compound, such as water blocking compound, and water absorbing powder to a core wire or wires of a stranded conductor or to subsequent layers of a stranded conductor, which are particularly suitable for use with a tubular strander, include a rotatable head, which may be positioned downstream of a wire strander. The core is drawn through a core passage where the filling compound is applied to the core and powder is applied to the filling compound. Strand through passages are provided through the rotatable head, for drawing the strand wires therethrough, without being coated. The strand wires are stranded about the core in a closing die. Preferably, the powder circulation circuit is a closed circuit, enabling recycling of the powder. The powder is preferably fluidized prior to its delivery to the applicator, and is withdrawn from the applicator under a slight vacuum. The rotatable head may include a filling compound applicator section and a powder applicator section, which are connected to each other so that they rotate together. Methods of applying filling compound and water absorbing powder are also described.
