Abstract

1380984 Endless pusher conveyers GEA LUFTKUHLERGESELLSCHAFT HAPPEL GmbH & CO KG 11 July 1972 [6 Aug 1971] 32329/72 Heading B8A The blocks 1 forming the support track for pushers 4 which engage fins (not shown) so as to assemble them on tubes (not shown), as described in Specifications 1,380,985, 1,380,986 and 1,380,987, have a parallelogram shape in plan view (as shown by the angle a in Fig. 6). This assists in maintaining to a minimum, wear between the shoes 5 of the pushers 4 and the blocks 1. The blocks 1 are made of surface hardened steel.
