Abstract: STORE AND FORWARD TYPE OF TEXT PROCESSING UNIT                     Abstract A store and forward unit having an output print station with convenience copying capabilities has connec-tions to diverse text signal sources and destinations.          Such diverse sources and destinations may have established textual format and control characters not necessarily shared with other sources and destinations.  The store and forward unit, upon receiving a set of text signals, examines the text control characters.  Based upon such examination, the store and forward unit processes such text without chang-ing the control characters provided that all destinations connected to such unit can use such control characters.  If, on the other hand, the destinations cannot use such control character, the unit adds sufficient control characters for allowing the received text as modified by the additional characters to be transmitted without text processing analy-sis to any of the connected destinations.  If desired, the control characters not usable or not recognized by a re-ceiving destination can be deleted prior to transmission to such destination.  Accordingly, when received text is to be retransmitted to a plurality of diverse destinations, the store and forward unit text processes the received sig-nals but once and supplies the text processed signals to the diverse destinations with only deletions of control charac-ters.

Abstract: IN SITU LEACHING PROCESS FOR RECOVERING URANIUM VALUES        Abstract of the Disclosure An in situ leaching process for recovering uranium values from a subterranean deposit which combines subsurface leach steps and surface processing steps to produce a high grade uranium product.  An alkaline carbonate and/or bicarbonate lixiviant, preferably ammonium bicarbonate, is flowed through the deposit to dissolve the uranium values The pregnant lixiviant is produced to the surface where it is passed through a concentration unit, e.g., ion exchange material, to remove the uranium values from the pregnant lixiviant.  An eluant comprising a strong solution of ammonium carbonate is then passed through the concentration unit to desorb the uranium values into the eluant in a much greater concentration than that which existed in the pregnant lixiviant.  The pregnant eluate is then heated to drive off ammonia and carbon dioxide, and the uranium values, i.e., yellowcake, are allowed to precipitate.  Both the ammonia and carbon dioxide are recovered for reuse in the process.

Abstract: Abstract of the Disclosure A hand-operated tool for assembling stackable elements of a multicontact electrical connector and for assembly conductors to the connector includes a head which is automatically positioned for effectively applying forces to the connector at each step of its assembly and to the conductors.  An installer causes the head to be moved downwardly through a first incremental distance toward a support into engagement with an element or conductors which are to be moved into secured engagement with an element held on the support.  The movement of the head through the first incremental distance and the initiation of its movement through a second incremental distance causes the head to be spaced from the support a predetermined distance which is automatically determined as a function of the number of elements held on the support in that step of the assembly.  When the head is moved through the second incremental distance, forces are applied which are sufficient to assemble the conductors and the elements.  A return of the head to an unoperated positions allows the installers to position another element or conductors for a next sequence of steps in the assembly of the connector.

Abstract: GASIFICATION FURNACE                      Abstract of the Disclosure A continuous gasification furnace and method of operation. The charge is fed into the furnace chamber between two rolls at least one of which is driven.  The furnace chamber can be sealed from the ambient atmosphere.  The bed of the furnace contains three zones from top to bottom, these zones are; a volatilization zone, a char reaction zone and an ash zone. Additionally, there can be a drying zone above the volatilization zone.  Fuel, air, and steam enter the lower portion of the fur-nace through strategically located inlet ports.  Fuel is used to start up the burning bed while carefully controlled steam to air ratio is used during continuous operation of the furnace. Simultaneously controlled steam cooling effects and exothermic reactions occur in the char reaction zone whereby all or con-trolled amounts of the oxygen is consumed so that pyrolysis can occur in the volatilization zone without the danger of combustion in that zone or combustion of the fumes leaving the bed.  The ash is discharged into an ash hopper designed so that the ash within the hopper supports the the charge bed.
