Abstract: 1292959 Conveyers DUNLOP HOLDINGS Ltd 3 Dec 1969 [6 Dec 1968 7 Dec 1968] 57936/68 and 58246/68 Heading B5N [Also in Divisions B8 F2 and H1] A passenger conveyer comprises an endless conveyer belt 60 and a handrail 67 (Fig. 5) each of which comprise respective layers in each of which is dispersed a magnetizable material. The belt and the handrail are supported by respective supports, in each of which is dispersed a magnetizable material of opposite polarity so as to provide a supporting force for the belt and handrail. The belt may be of natural or synthetic rubber having spaced layers of transversely disposed metal cords 13 (Fig. 1) between which is disposed cotton tensile elements 12. A layer 15 of rubber contains dispersed magnetizable material such as barium, strontium, or lead ferrite. The support may be a rigid plate 16 having a layer 17 of similar form to the layer 15 of Fig. 1. The polarity of the layer 17 is the same as that of the layer 15. The layer 17 may, however, be of orientated resin bonded ferrite or sintered barium ferrite layers 15 and 17, and may be magnetized in patterns, e.g. in longitudinally extending zones (Fig. 2). The belt may also be supported along its edges by rollers (23), (Fig. 23, not shown). The belt may be tensioned by displaceable rollers (26). The belt may be driven by a linear motor. The same (magnetic) mode of support may also be used on the return run of the belt. The handrail is of rubber polyvinyl chloride, or sulphonated chlorinated polythene, and is of C cross-section (Fig. 4, not shown), the support being of T crosssection. The magnetizable layer may extend around the curved links of the handrail so as to provide a degree of lateral guidance. The layers 15, 17, instead of being continuous flexible layers, may each comprise a series of spaced plates.
