Abstract: BANKING MACHINE CONTROL            ABSTRACT OF THE DISCLOSURE         Bank notes are accurately delivered to a customer in a preselected amount at an exit throat from a storage bin. Delivery of the bank notes from the storage bin is on an individual basis to an escrow station where the number of bills of currency representing the  reselected amount is collected for delivery to the customer at the exit throat. In the transport path from the storage bin to the escrow station multiple bank notes and trailing bank notes are detected to control the operation of the banking machine to deliver the notes at the escrow station either to the customer or divert a miscount of the bank notes to a divert bin.  Initially, the process for transporting bills from the storage bin to the escrow station actuates a main drive motor of a transport system. Bank notes are fed from the storage bin to the transport system and if more than one bill is fed to the transport system all but one are returned to the storage bin.  The travel time of a note past a check point is monitored to determine an over-lapping note condition.  Multiple bank notes traveling together through the transport system are sensed after completion of the timing function.  Bank notes delivered from the transport system are assembled in an escrow station for a subsequent transporting to the exit throat.

Abstract: METHOD AND APPARATUS FOR MIXING GASEOUS OXIDANT    AND LIXIVIANT IN AN IN SITU LEACH OPERATION            Abstract of the Disclosure Method and apparatus for mixing a gaseous oxidant (e.g., oxygen) and a lixiviant (e.g., an aqueous carbonate solution ) at a downhole Location before the oxygen-saturated lixiviant is injected into a formation to be leached.  The inven-tion involves eatablishing a mixing zone in the well by positioning a mixing means, comprising a housing, in the well at the downhole location.  Lixiviant is flowed down the well and through a restrictive opening in the housing to substantially increase the flow velocity of the lixiviant.  At the same time, gaseous oxidant is fed to the housing and is trapped therein by the increased velocity of the lixiviant and by packing material in said housing.  The lixiviant flows through the trapped oxidant which, in turn, dissolves into the lixiviant to saturate same.  Additional packing material is provided in the housing to remove undissolved oxidant from the saturated lixiviant before it is injected into a formation to be leached.

Abstract: ABSTRACT A tone signal detector for use in paging receivers and the like is disclosed.  In known tone signal detectors a waveforms converting circuit converts incoming tone signals to pulses which are applied as gating pulses to a gate circuit to permit clock pulses to be counted which gives a count which can be equated to the tone.  However, a threshold in the waveform converting circuit is liable to vary, resulting in variations in the duty factor of the gating pulses and so the detector is subject to failure with respect to some tone signals.  The tone signal detector of this invention is not adversely effected by threshold variation in the waveform converting circuit.
