Abstract: 1,264,124. Mould locking device. VITAFOAM Ltd. 16 May, 1969 [17 May, 1968], No. 23504/68. Heading B5A. [Also in Division E2] Moulds for the production of a foamed elastomeric article, e.g. an automobile seat, and each comprising a cavity defining base 10 and a lid 11 which is pivotally attached thereto at hinges 12, are locked in the closed position by a bar 20, carried by a screw member 17 on the lid 11, which passes through a slot 22 on a mould base bracket 21 and is then rotated to a locking position thereacross, the bar 20 being automatically actuated to the locking or unlocking alignment with the slot 22 by conveying the moulds past stations at which the screw 17 is rotated by engagement of a profiled lever member 18 thereon with a stationary member 26. The moulds are conveyed by trolleys 23 which are drawn by a chain conveyer (not shown) and run at wheels 24 thereon on tracks 25, preventing lateral movement of the trolleys 23. During mould unlocking, movement of the bar 20 beyond the position in alignment with the slot 22 is prevented by the engagement of a dependant portion of the member 18 with a lid abutment 19. The mould is opened and closed, respectively after unlocking and before re-locking by the engagement of a roller 16, carried by the lid 11, along a ramp 27. In a modification, opening of the lid 11 prior to the ramp 27, is commenced by a platform 31 which rises to engage the roller 16 thereby breaking any seal caused by a release wax coating in the mould, and partial vacuum arising during cooling thereof. When the platform 31 is actuated by a valve controlled pneumatic or hydraulic cylinder 28, the upward and downward displacement thereof is respectively initiated by the roller 16 contacting a contactor 30 pivotally mounted on the platform 31 and a contactor 33 on the ramp 27. Alternatively, the platform 31 may be actuated by an electric motor, the action whereof is controlled by photo-electric cells, or by a sonic beam device. The bar 20 is hollow and is fracturable in the event of a failure to operate member 18 during unlocking.

Over this sleeve is wound a weakly conducting strip 15 which interconnects the conductor smoothing 7 of the two cables. The strip 15 may be a weakly conducting strip of woven fabric or a layer of an ethylene-propylene-diene rubber which has been rendered weakly conductive. Over this strip 15 and the conductor insulation 6 near the sleeve there is spread a layer of a few microns of ethylene-propylene-diene-rubber which has been dissolved together with a cross-linking or vulcanization agent, an accelerator and a.stabilizer in trichloroethylene. After the escape of the solvent this layer is briefly heated by an open gas flame to cause cross-linking or vulcanization, so that this layer 2 is firmly bonded to the conductor insulation 6. A dyestuff is included in the layer 2 which changes colour when the crosslinking or vulcanizing temperature is reached. A layer of adhesive is applied over the crosslinked or vulcanized layer and a cast body 11 of epoxy resin is applied. Each cable is provided with a layer of conductive lacquer 12 over the insulation, over which a conductive textile strip 13, an electrical screen 8 and an outer sheathing 9 of P.V.C. or polyethylene are arranged. For potential control over the resin body 11 a layer of conductive lacquer 16 and a weakly conductive strip 17 of woven fabric are applied, and a sheath of wound strips 18 of P.V.C. is then applied and heated to weld the strips together. The layer 2 could cover the end of the cable sheathing 9 and in a cable termination (Fig. 1, not shown) a similar layer may be applied between the cable insulation and a resin body, the resin being based on epoxy resin or polyurethane resin. The cable may be a heavycurrent cable or a telecommunications cable. The layer 2 may contain, as a cross-linking agent, a peroxide either alone or in combination with an activator, e.g. dimethyl acrylate or with sulphur. It may also contain an anti-ageing material, e.g. a material chosen from naphthyl amines, phenylene diamines, imidazoles, cresols, alkyl- or aralkyl-substituted phenols and derivatives thereof.
