Abstract: ABSTRACT OF THE DISCLOSURE         In a digital video signal processing apparatus having error correcting and concealing capabilities, a video signal is converted to a digital signal and transmitted or recorded with error detecting and error correcting signals.  Upon receiving or reproducing the transmitted signal, an error in the digitized video signal is detected by means of the error detecting signal, and corrected, if possible, by means of the error correcting signal.  If the error is so extensive that its correction by the error correction signal is not possible, the erroneous signal is concealed by its replacement with a substantially corresponding signal of the previous field which has been stored in a suitable memory.

Abstract: ABSTRACT     The cementing collar described herein is de-signed primarily for cementing operations in oil or gas wells.  The basic assembly includes a collar, an outer sleeve slidable in the collar, and an inner sleeve slidable in the outer sleeve. The collar and outer sleeve each have cementing ports therein.  When the assembly is being run into the well casing, the collar and both sleeves are secured by shear pins in a position such that the cementing ports are closed.  To open the cementing ports a trip bomb is dropped into the casing to engage a seat inside the outer sleeve.  This causes the pins to shear and permits the outer sleeve to move down to a position in which the sleeve ports line up with the collar port.  After cementing has been completed, a plug is flowed down the casing to engage the inner sleeve.  Fluid pressure is applied behind the plug to shear the pins a second time. This moves the outer sleeve further down to a posi-tion in which the cementing ports are again closed.   28,242-F         -14-

Abstract: ABSTRACT Disclosed is a digital signalling receiver responsive to an input in-band audio frequency signal digitized at a first sampling frequency and containing pushbutton telephone (PB) signals, each of which consist of one select-ed out of a predetermined plurality of lower group of frequencies and the other one out of a predetermined plurality of higher group of frequencies   The whole frequency range of the audio frequency signal is split into two frequency bands in response to the digitized signal, one band is eliminated, and a consequent signal is produced lying within the other band and containing both or either of the lower and higher groups of frequencies of the PB signals. The consequent signal is resampled a predetermined number of times at a second sampling frequency obtained by reducing by 1/2 each time the first sampling frequency and the frequency band signal not containing the lower and higher groups of frequencies of the PB signals are eliminated, thereby generating two sets of signals, one containing frequencies lowered corresponding to the lower group  of frequencies and the other one, containing frequencies lowered corresponding to the higher group of frequencies.  The two sets of split signals are fed to two sets of band-pass filter groups for detecting predetermined PB signals which in turn feed energy extracting circuits.  The PB signals ale deter-mined from the outputs of the energy extracting circuits.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for sequentially and selectively separating gold and platinum group metals from aqueous solutions containing them is disclosed.       First, ruthenium and osmium are oxidised to their tetroxides and then removed from the solution. Then, gold is removed by solvent extraction preferably with dibutyl carbitol.  Next, palladium and platinum are removed by solvent extraction with an alkyl sulphide and tributyl phosphate respectively, care being taken to reduce iridium in solution before platinum extraction to prevent it extracting with the platinum.  Then the iridium is reoxidised and removed from solution.  Finally, rhodium is removed from the solution.       Using this process gold, platinum and palladium of saleable purity can be extracted directly without the need for further refining steps.

Abstract: 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 modules.  Each device controller includes logic which insures that only one port is selected for access at a time.  The multi-processor system includes a distributed power supply system which insures uninterrupted operation of the remainder of the multi-processor 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 mainten-ance 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         A system for moving large quantities of pulverulent material from receiving hoppers, such as those of a fly ash precipitator, into a pressurized air conveyor pipeline.          Separate auger conveyors move material from a first line of receiving hoppers and from a second line of receiving hoppers into gravity material inlets at opposite ends of an effectively airtight casing of a pressure mechanical conveyor wherein auger conveyor screws of opposite hand move it toward a central outlet through which it drops into the pressurized air conveyor pipeline.  The auger conveyors and the pressure conveyor augers operate continuously; and the system is cycled to alternately feed material into the pressure conveyor casing at receiving hopper pressure, which is about atmospheric pressure, and out of the pressure conveyor casing at pipeline pressure.  The cycles of two or more pressure conveyors are out of phase with one another so they feed material into the pipeline consecu-tively to provide level pipeline flow.  If the material comes from precipitator hoppers which are filled by material dropping from a gas stream, the airtight pressure mechanical conveyor is at the upstream ends of the lines of receiving hoppers.
