Title: Data processing apparatus
IPC: G06F7/36
Filed: 1972-10-06
Abstract: 1378982 Data sorting and merging system INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [17 Nov 1971] 46151/72 Heading G4M A programmed data processor using memory discs is used to sort strings of data and merge the sorted strings into a final ordered string. The sorting is carried out in four Phases. In the first Phase, Phase 0, various parameters required for the sorting process are calculated. Blocking Factor B equal to the number of records that can be read into or out of store in a single operation, G, equal to the number of records that can be held in store at one time and equal to the storage area less the area required for buffers and stored programs and M2 and M3, the merge orders for Phase 2 and Phase 3 and equal to the number of sequences that can be formed in one pass to form a longer sequence. Phase 1 is the Internal Sort (Figs. 9A, 9B, not shown). Data from the input file is read into the store and the lowest numbered record is fed into a work file. The next record, if it is higher than the last record in the work file, is read into store and the procedure repeated. If a new record is lower than the last record in the work file it is read into store and tagged as unuseable. The procedure is repeated until either the output buffer is full or all the records in store are tagged and so produce a sequence break. In the latter case the tags are cleared and a new output string is produced. In the former the data is stored and the sorting proceeds. If the final number of strings produced is less that or equal to M3 then Phase 3 is performed. Otherwise Phase 2 is performed. Phase 2 is the External Sort or Intermediate Merge (Figs. 12A, 12B, 12C, not shown) in which the strings from Phase 1 are merged to form a number of strings equal to or less than M3. An optional sequence for merging is calculated so that the minimum number of record handlings occur to produce the M3 strings and this may involve using null strings, i.e. strings containing no data so that less than M2 actual strings are used in the merge (Figs. 16, 17, not shown). When the M3 strings are produced Phase 3 performs the final merge.

Title: Improvements in or relating to nuclear vapour generating plant
IPC: G21C1/08
Filed: 1964-11-16
Abstract: 1,068,080. Reactors. BABCOCK & WILCOX CO. Nov. 16, 1964 [Nov. 15, 1963; Nov. 29, 1963], No. 46609/64. Heading G6C. In a nuclear superheated steam generating plant suitable for marine use, pressurized primary water cools the reactor and produces superheated steam in a once-through flow of secondary coolant water in heat exchangers within the pressure vessel. To accommodate changes of operating conditions the flow of secondary coolant through the exchanger may be controlled. An outer chamber surrounds the pressure vessel and is water filled to serve as a biological shield. The external surface of the pressure vessel is lined with insulating and shielding material. Dissipation of decay heat during shut-down is effected by connecting the heat exchangers to an external water tank. The pressure vessel has a safety valve. Under normal operation the primary coolant is pumped vertically upwards through the core and downwards through the heat exchangers disposed round the core. Gas pressurization of the primary coolant is used. Control rods are adjusted vertically, the flow of coolant past the core is restricted and natural circulation is employed at low loads.

Title: Improvements relating to the treatment of spent fuel elements from atomic reactors
Inventor: TJALLDIN OLLE
IPC: G21C19/38
Filed: 1961-12-29
Abstract: The separation of uranium and zirconium from spent fuel elements consisting of uranium fuel enclosed in a capsule consisting mainly of zirconium, is effected by oxidizing the capsule to form zirconium oxide and subsequently carrying out a selective leaching process which dissolves the spent uranium fuel but not the zirconium oxide. The oxidation of the capsule is effected by steam, containing preferably 40-90% by volume of nitrogen and less than 30% by volume of oxygen at a temperature above 700 DEG  C., preferably 800-825 DEG C.  The spent uranium fuel is generally UO2; however, in cases where this is not so the vacuum fuel is oxidized before leaching to form UO2 under the conditions indicated above for the oxidation of the zirconium capsule.  Preferably the UO2 is further oxidized to U3O2 before leaching, by the action of a gas containing more than 50%, preferably more than 90%, of oxygen and less than 5% by volume of steam, nitrogen or some other inert gas, at a temperature of 300-600 DEG  C.  The leaching process is carried out using dilute nitric acid having a concentration of 4-4.5 moles/litre.  The nitric acid solution is preferably used in such a quantity that, after all the uranium oxide has been dissolved, the solution contains about 500 gm. of uranium/litre and a slight excess of nitric acid.

Title: System for preventing cracking of glass ribbon in plate glass manufacturing
IPC: C03B18/02
Filed: 1975-11-12
Abstract: 1485895 Float glass CENTRAL GLASS CO Ltd 12 Nov 1975 [14 Nov 1974] 46681/75 Heading C1M [Also in Divisions G1 and G3] In a glass manufacturing process in which glass is floated on molten metal, the glass is scanned by a laser beam to detect non-molten inclusions, and a heater is activated adjacent a conveyer which removes the glass from the metal to soften the detected inclusion; cracking at the point of removal is thus avoided. In Fig. 2 a beam produced by a laser 28 is scanned by a mirror 30, and light reflected from the glass is photoelectrically detected at 32. The resulting signal is amplified and compared with a preset reference at 36 to produce a warning signal and to activate a heater 20. The reference level is chosen according to the glass thickness and the expected size of the inclusions. The heater controller 40 may also receive a signal indicative of the speed of movement of the glass. In a more complex arrangement, Fig. 3, the comparator also activates a position sensor 50 which determines the lateral position of the inclusion, so that an appropriate one of a set of heaters 20 may be energized. The sensor 50 opens the correct heater switch 54 via a selector 52, and the controller 40 determines the energy delivered to the heater according to signals from the comparator 36 and a velocity detector 60 (the latter may sense the conveyer roller rotation rate). A computer 62 receives a start signal from switch 54 and also a velocity signal; it resets the switch when the inclusion has reached the conveyer.

Filed: 1976-11-10
Abstract: 1527559 Anti-skid braking systems GENERAL MOTORS CORP 10 Nov 1976 [20 Nov 1975] 46754/76 Heading F2F Voltage signals proportional to wheel speed are differentiated by a circuit 28, 30, 32 to provide a first signal to point 34, and are also supplied to a circuit comprising diode 42, capacitor 38 and resistor 40, which produces a second signal to point 34. On rapid deceleration of the wheel, the second signal has a delay rate, e.g. representative of deceleration on a low friction surface, which provides a reference for anti-skid control. The two signals are summed and the output used as an anti-skid control signal. As described they are integrated by circuit 46 to provide a speed error signal, and the brakes are released when this signal is greater than a reference signal fed to the negative input of comparator 64. This reference signal has a fixed component from source B+, via resistor 72 and a variable element generated by circuit 78 so that a greater reference signal is produced during the first cycle of anti-skid operation, e.g. to allow for the effect of axle wrap.
