Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for hydraulically hoisting particulate solid mined minerals from one mine level to another in which bore holes are used as conveying conduits for the mineral-water mixtures.  Batches of the mineral are charged into a pressure vessel at a lower level and discharged intermittently into a borehole  conduit system in which water is circulated, under pressure, between the two mine levels.  The mineral is separated from the conveying water at a higher level by a conventional dewatering  apparatus and the water is returned to the vessel for mixing with a new batch of mineral.  The method is conducted cyclically with mineral batches being charged to and then discharged from the vessel at controlled intervals, the control being achieved by valve means which alternately isolate and integrate the vessel with the water circuit.  The pressure vessel is further characterized by a discharge port in a sidewall of the vessel connected to a discharge pipe outside the vessel.  The other end of the discharge pipe is connected to the hoist borehole.

Abstract: ABSTRACT         Comparator means respond to the current levels through an inductive load to generate HIGH and LOW level outputs causing first switch means to connect and dis-connect power to the load.  When the load current initially exceeds a peak load actuation level  flip-flop means responsive to the corresponding change In comparator output levels change the current through an auxilliary sense resistor coupled to the sense input of the com-parator means.  In one embodiment  a one-shot multi-vibarator prevents a change in the current to the auxil-liary sense resistor for a fixed period after the com-mencement of a load actuation signal.  The subseguent HIGH end LOW comparator output levels are fed back to the comparator reference input to switch the reference voltage thereat so as to represent first and second levels of the current sufficient to maintain actuation of the load.
