Patent CA-1114940-A (CA)
Title: Facsimile system
Inventor: HARBAUGH STEVEN K
IPC: H04N1/36
Filed: 1977-06-02
Granted: 1981-12-22
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a facsimile system having a trans-mitter for optically scanning input copy to produce modulated electrical signals to be transmitted to a receiver.  The receiver responsively controls output optical scanning to form output copy as a reproduction of the input copy.  Signal processing in both the trans-mitter and receiver employs spatial coding.  In the transmitter scanner, a spatially coded reference signal, generated by the scanning beam and a spatial mask, is employed.  In the receiver scanner, a spatially coded reference signal, generated by the scanning beam and an identical spatial mask is employed also.  Therefore, the transmitter and receiver scanners are spatially synchro-nized without the need for real-time synchronization.

Title: Intelligent input-output interface control unit  for input-output subsystem
Inventor: COOK DARWEN J

Granted: 1981-11-10
Abstract: Abstract of the Disclosure An intelligent Input-Output Interface Control unit, des-ignated as a Line control Processor, which serves as a cont-rol channel for data-transfers between a main data process-ing system and a plurality of different peripheral devices. The Line Control Processor operates on a standard communica-tions and control discipline which makes the eccentricities of various peripheral units transparent to the Main System. Once initiated, the Line Control Processor can execute the data-transfer instructions within the overall system so as to relieve the central processor of involvement in these tasks.  Message-block length data buffer memories are pro-vided within the Line Control Processor to permit data-transfers to and from the peripheral device, at the speed suitable to the peripheral device; and also to permit data-transfers between the Line Control Processor and the Main Memory at the high transfer speeds permitted by Main Memory. Each Line Control Processor is provided with capabilities of handling the idiosyncracies of the peripheral device to which it is dedicated while it provides status control information to the Main System and helps serve as a building block to facilitate expansion of peripheral devices within a data processing system on a simple economic basis.  The message-block length buffer memories prevent access errors since complete record length message transfers can occur in any given data-transfer cycle, barring any emergency interrup-tions.

Abstract: PROCESS FOR EXTRACTING URANIUM FROM ITS ORES WITH ALKALINE EARTH CARBONATE AND BICARBONATE  SOLUTIONS IN THE PRESENCE OF CARBON DIOXIDE     ABSTRACT OF THE DISCLOSURE         Uranium is extracted from its ores, whether the ores are still in underground deposits or removed therefrom by oxidizing the uranium to a valency of 6 by means of oxygenated water or oxygen in the presence of carbon diox-ide, dissolving the uranium by means of alkaline earth carbonate and bicarbonate lixiviant solutions in the pre-sence of carbon dioxide under a pressure below 60 bars and at a temperature of from O tc 100°C, then separating the insoluble substances from the lixiviant after expansion to 4 bars or less to produce a calcium uranyl carbonate liquor.          Uranium is recovered from this Iiquor after expansion under vacuum by either: (a) a limewash treatment at a pH of 8 to 9 which precipitates calcium carbonate and separating a liquid fraction which is treated in turn with a limewash at a pH of 10 to 12 and allows the calcium uranate to be deposited, or (b) separation of the calcium carbonate resulting from the ex?ansion and subjecting the liquor to a limewash treatment at a pH of 10 to 12 to form a mixture of calcium uranate and calcium carbonate.  After atmospheric expansion and separa-tion of the calcium carbonate resulting from this expansion, the liquor may be treated with hydrogen peroxide to precipi-tate uranium peroxide or it may be passed over a bed of anionic resins to fix the uranyl carbonate ions.

Abstract: ABSTRACT OF THE DISCLOSURE:           A process of calcining limestone or hydrated lime by a thermal treatment with hot gases in a rotary kiln in which the charge is moved countercurrently to the flow of the kiln atmosphere and oxygen-containing gases are introduced into the rotary kiln through the shell thereof at a plurality of points.  The process of the invention is characterized in that  at least part of the hot gases are produced by feeding solid carbonaceous fuel into the rotary kiln at the charging end thereof and injecting oxygen-containing gases through nozzle blocks into the charge which is disposed over nozzle blocks into that region of the rotary kiln which begins at the point where ignitable particles of the solid fuel first appear and terminates at a point which is spaced from the charging end by not more that 50% of the length of the kiln, the oxygen-containing gases being injected through shell pipes at least into the free space of the kiln of the afore-said region.  The advantages afforded by the invention reside in that the length of the heating-up zone of the rotary kiln is greatly reduced and, as a result, either the throughput rate of a give kiln is increased or a smaller kiln may be used for a given throughput rate.  In addition, the differ-ence between the gas temperature and the bed temperature is minimized and the exhaust gas temperature is minimum too.          The lower heat content per unit of volume reduces the danger of a formation of crusts and increases the durability of the refractory lining.  The total energy consumption is much reduced because the heat content of the volatile combustible constituents of the solid fuel is utilized to a large extent, the gas temperature in the free kiln space and consequently in the exhaust gases is reduced, and the direct gasification of carbon on the bed is decreased because the accumulation of heat which would otherwise be possible here is avoided.

Abstract: METHOD AND APPARATUS FOR PIPE JOINT LOCATOR, COUNTER AND DISPLACEMENT CALCULATOR     ABSTRACT OF THE DISCLOSURE           The invention is a novel method and apparatus for counting pipe joints, passing through a bell nipple, going downhole and uphole by sensing, at spaced apart positions along the nipple utilizing magnetic fields, for the presence of a joint.  Each sensor develops signals as the joint passes it and a logical network determines which direction the pipe joint is traveling, adds a plus count to the joint counter for joints going downhole and subtracts a minus count from the joint counter when a joint is sensed coming uphole.  Another logical circuit converts the joint count to a stand count, and the negative signals from the stand count trigger an adder network to introduce a binary number to a numeric readout display, which number is indicative of pipe displacement per stand, withdrawn from hole.
