Abstract

1452913 Reciprocating conveyers COAL INDUSTRY (PATENTS) Ltd 21 June 1974 [17 July 1973] 33871/73 Heading B8A [Also in Divisions E1-E2] The actuators of displaceable paddles, e.g. linear or pivotally displaceable paddles, of a rock debris conveying or goaf-stowing apparatus, mounted on advanceable roof props, e.g. apparatus such as described in the referred to Specifications 1,385,089, 1,361,002 and 1,255,197, are controlled by a control system that causes the conveyance traversals of the paddles to occur sequentially instead of simultaneously as in the apparatus of the referred to Specifications. Preferably the control system involves for the hydraulically powered actuators 21-25 a series of high pressure sensitive, sequence hydraulic valves 63-67, a stop valve associated with one of the sequence valves to override the sequence valve, a control valve which in its "off" condition overrides the control system to prevent actuation of the actuators and which can only be set in its "on" condition manually, and a pilot-operated, hydraulic pressure sensitive valve which senses the pressure of the hydraulic supply and which actuates the control valve into its "off" condition when the sensed pressure falls below a preselected level. The control system is such that at least one of the paddles will make a non-conveying traversal before the conveying made sequence of the paddles is completed.
