Abstract: MULTIPROCESSOR SYSTEM          Abstract of the Disclosure A multiprocessor system the kind in which two or more separate processor modules are interconnected for parallel processing includes two redundant interprocessor buses dedicated exclusively to interprocessor communication.    Any processor module may send information to any other processor module by either bus.  The buses are shared in use by the processor modules on a time-sharing basis.  Use of each bus is controlled by a special bus controller.         The multiprocessor system includes an input/output system having multi-port device controllers and input/output buses connecting each device controller for access by the input/output channels of at least two different processor module Each device controller includes logic which insures that only one port is selected for access at a time.         The multiprocessor system includes a distributed power supply system which insures nonstop operation of the remainder of the multiprocessor system in the event of a failure of a power supply for a part of the system.  The distributed power supply system includes a separate power supply for each processor module and two separate power supplies for each device controller.  Either one of the two power supplies provides the entire power for the device controller in the event the other power supply fails.          The distributed power supply system permits any processor module or device controller to be powered down so that on-line maintenance can be performed in a power-off condition while the rest of the multiprocessor system is on-line and functional.         The multiprocessor system includes a memory system in which the memory of each processor module is divided into four logical address areas -- user data, system data, user code and system code.  The memory system includes a map which translates logical addresses to physical addresses and which coacts with the multiprocessor system to bring pages from secondary memory into primary main memory as required to implement a virtual memory system.  The map also provides a protection function.  It provides inherent protection among users in a multiprogramming environment, isolates programs from data and protects system programs from the actions of user programs.  The map also provides a reference history information for each logical page as an aid to efficient memory management by the operating system.         The multiprocessor system includes in the memory of each processor module an error detection and correction system which detects all single bit and double bit errors and which corrects all single bit errors in semiconductor memory storage.

Abstract: ABSTRACT OF THE DISCLOSURE An energy saving garbage disposal unit that is disposed under a tank and connected to the drain thereof in a conventional manner.   Actuation of the unit is provided by pressurized water from a domestic source thereof.   Pressurized water entering the unit serves a twofold purpose;  first, driving a turbine to actuate a garbage masticating assembly, and second, after discharge from the turbine the water mixing with masticated garbage and serving to flush the latter down a waste line that extends from the unit. The unit masticated garbage to particles of a predetermined size prior to discharging the particles to the waste line, with the possibility of the waste line becoming clogged or stopped up by garbage particles of substantial size being reduced to a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a process for the treatment of an uraniferous ore containing sulfur in the form of sulfates or sulfides with one or more alkaline solutions containing sodium carbonate in the presence of an oxidant, for extracting uranium in the form of a soluble uranium salt in said solution.          It comprises subjecting the ore, in a first step, to the action of a dilute pre-leach solution of sodium carbonate, whose concentration does not substantially exceed, or by very little, that which is required for the solubilization of the major part of the sulfur initially contained in the ore to convert it to sulfate in the presence of the oxidant and, in a second step, to the action of a leach solution, more concentrated in sodium carbonate, enabling the extraction and solubilization in the medium of the major part of the uranium still contained in the ore, not extracted in the pre-leach medium of the first step.

Abstract: ABSTRACT OF THE DISCLOSURE   In order to suppress high-frequency currents in the bearings of shafts in high frequency treating apparatus, the electrical capacitance of the bearing is arranged in the configuration of an electric quadrupole in such a manner that the high frequency voltage becomes a minimum.  A further impedance is connected in series with the bearing impedance between the bearing housing and the housing of the treatment chamber, the sum of the further impedance and the impedance of the shaft being great in comparison to the bearing impedance.  An additional impedance inside the treatment chamber is connected between the shaft and the housing of the treatment chamber, the value of the additional impedance being low in comparison to the capacitive impedance of the bearing.  Suppression of the bearing currents is desirable to prevent electroerosive destruction of the bearings.
