Title: Composition and method for agglomerating ore
Inventor: WALKER DANIEL D JR
IPC: C22B1/243
Filed: 1992-03-12
Abstract: The binder composition for agglomerating ore fines of the invention is a mixture of (1) a reactive calcareous component, (2) a reactive siliceous and aluminous component, and (3) a sulfate compound.  Preferably, the binder composition is comprised of 10 to 80 % by weight lime as the calcareous component, 5 to 50 % by weight fly ash as the siliceous-aluminous component and to 80 % by weight sulfate compound such as gypsum. Most preferably, the siliceous-aluminous component is a low carbon content fly having less than about 0.5 % by weight carbon content. The preferred lime component of the binder composition is either a high calcium line with greater than about 90 % by weight CaO content ora dolomitic lime. In the process for recovery of metals from ores having ore fines of the metals, the ore fines are first agglomerated by adding thereto a binder composition, the binder composition comprising about 10 to 80 % by weight lime; 10 to 80 % by weight sulfate compound and 5 to 50 % by weight siliceous-aluminous material. A leach bed is formed of the agglomerated ore and the bed is leached with a leaching agent to there-by form a leach liquor. The metal values are recovered from the leach liquor.

Title: Control of a radio communications system base station
Inventor: HAGSTROEM ULF E
IPC: H04W88/08
Filed: 1994-03-15
Abstract: ABSTRACT OF THE DISCLOSURE      In a radio communications system having at least one base station, the base station including a plurality of transceivers, a control method and apparatus includes the steps of comparing the number of transceivers in a call state to a first predefined number.  If the number of call state transceivers is greater than the first predefined number, then all of the idle transceivers except at least one are switched off.  If the number of call state transceivers is less than the first predefined number, then all excess idle transceivers are switched off.  Also, after switching off the first subset of the plurality of transceivers, a second subset may be switched off after waiting a predetermined time period. The number of operational transceivers in the second subset is less than in the first subset.  To further reduce the power consumption of the base station, a first group of radio communications system subscribers is designated as a high priority group, and a second group of subscribers is designated as a low priority group. The system is designed to grant service to the high priority group, while denying it ot the low priority group.  The control methods and apparatus are useful, for example, for reducing power consumption and/or traffic handling capacity of a base station.
