Title: Improvements relating to the recovery of sulphur values of acid sludge
Inventor: CUMMINGS DONALD RAY
IPC: C01B17/58
Filed: 1958-07-29
Abstract: In the recovery of sulphur values from acid sludges containing H2SO4 by decomposition by <PICT:0857111/III/1> contact with hot coke to form SO2 and coke, where the combustible components of the product gases are oxidised in a combustion chamber, the coke is heated at least in part by means of direct contact with a mixture of hot SO2-containing gases from the combustion chamber and recycled cool SO2-containing gases from heating the coke.  The coke may be heated in a static bed, moving bed, fluidised bed, or mechanically agitated bed, a rotary kiln, or conveyer, or elevator.  The direct gas heating of the coke may be used in combination with partial oxidation of the coke, indirect heating, or direct heating from combustion products from an externally fired furnace.  In Fig. 2 the SO2-containing gases from coke heater 12 pass through 4 and part is recycled through 5. The remainder of the gases pass into combustion chamber 6 where air and, if necessary, fuel are added at 7, 8 to oxidise combustible constituents.  The SO2-containing gases are removed at 9 and part is withdrawn as product at 10, and part returned through 11 with the SO2-containing gases by-passed through 5 to the coke heater. Heated coke is passed through 13 to decomposer 14 where acid sludge enters at 15.  Part of the coke is withdrawn at 16 and part is returned to the heater through 17.  The SO2-containing gases pass to hydrocarbon removal at 18 where condensible hydrocarbons are extracted in a spray tower or heat exchanger. The remaining SO2-containing gases are passed at 19 to the heating gases before, or preferably after, the coke heater.  In an alternative apparatus (Fig. 1 not shown), a separate decomposer is not used, and the acid sludge is passed to a combined coke heater and decomposer, and means for hydrocarbon condensation is not provided.

Patent GB-1179005-A (GB)
Title: Data processing system
IPC: H04L13/08
Filed: 1967-05-26
Abstract: 1,179,005. Buffer storage systems. INTERNATIONAL STANDARD ELECTRIC CORP. 26 May, 1967 [31 May, 1966], No. 24582/67. Heading G4C. Telegraph lines are sampled under control of status storage means which indicates for each line whether a character is being received from it and if so what progress has been made with that character, the received characters being assembled bit-by-bit from the samples in assembly storage means which feeds main storage means which in turn feeds a processor via block storage means. A line counter scans 128 duplex telegraph-lines in turn and simultaneously scans line speed switches to indicate the line speed of the currently scanned line to logic associated with a status storage loop. The status loop comprises a delay line and an 8-bit shift register as does an assembly loop. As each telegraph line is scanned, 8 bits relating to it appear in the shift register associated with each of these two loops. The 8 status loop bits consist of 5 scan count bits, preset in accordance with line speed and incremented/decremented to control sampling of the telegraph line at the middle of a bit period, and also 3 character status bits which are decoded to gate the bit from the telegraph line into the correct bit position of the 8-bit slot relating to it in the assembly loop to build up a 5-bit character. The other 3 bits are for an end (or start) of message indication.. When complete, a character is sent to main storage where it is held in one of 8 shift registers (which may be replaced by lumped constant delay loops), depending on the originating telegraph line, until an empty character slot (marker bit absent) in such 8 slots relating to the given telegraph line occurs in that one of 8 delay line loops respective to the shift register. Thus the main storage has 8 delay loops, each catering for one-eighth of the telegraph lines (i.e. loop 1 caters for lines 1, 9 &c., loop 2 for lines 2, 10 &c.) and each having 8 character slots for each line it caters for. When a set of 8 character slots is full, as indicated by a marker bit being present in the last slot, the 8 characters are transferred to a block store comprising a 64-bit delay loop, and from there, when a processor is ready, the 8 characters are transferred as two words (each 4 characters in parallel) from a 32-bit shift register fed from the loop, preceded by the line identity derived from the line counter. The delay lines (except the lumped constant lines mentioned) may all be magnetostrictive lines. Data transfer in the other direction is also possible.

Title: Apparatus for dispensing food receptacles
Inventor: CEASE WILLIAM WALLACE
IPC: G07F11/46
Filed: 1965-06-10
Abstract: 1,079,167. Unstacking apparatus. CEASE CENTRAL Inc. June 10, 1965, No. 24611/65. Headings B8C and B8S. Apparatus for supporting a stack of food containing receptacles and successively dispensing individual receptacles from the bottom of the stack comprises means for housing a vertical stack of food receptacles, vertically reciprocable members disposed on opposite sides of the stack - carrying stack - engaging members, a pair of parallel rails in a lower portion of the housing to support the lowermost receptacle of a stack, and means for retracting the stack-engaging members after they have moved downward past the rails and for again projecting them after they have moved back up past the rails. The stack, comprising plates 124 and stack bands 125, is supported on dogs 148, between side walls 121. The dogs are pivoted at 149 on support arms, outside the side walls 121, and vertically reciprocable by means of a motor and a single revolution clutch. Retaining flange members 136 each carry a cam slot 152 in which a pin 150, carried by the dog 148, runs. In the rest position, Fig. 11, the dogs engage under spaced lateral lugs 128 on the lowermost band 125 supporting the stack. When the motor is actuated the supports descend, and hence the dogs, lowering the stack. The lugs 128 pass through complementary notches in rail members 130, supported on the walls 121, the rim of the plate 124, however, being arrested by the rail. The dogs continue to descend, carrying the lowermost band, until the pin 150 engages the bottom of the cam slot 152, when the dogs are swung out and the band falls into the bottom of the housing. The supports then rise, with the dogs maintained in the retracted position by over centre gravity action, until the pins engage a shoulder in the cam slot, projecting the dogs back above the rails 130, on which the stack is now resting. Continued upwards movement brings the dog into engagement with the lugs of the next band, lifting the stack off the lowermost plate 124 which is retained on the rails 130 by a hold-down member 154 pivoted on the side walls 121. The plate 124 is then ejected horizontally by a member (60), Fig. 1 (not shown), sliding in guide rails 158, 159, and actuated by a differential pulley mechanism, to deliver the plate to the front of a cabinet, in which more than one stack may be housed. A closure may be provided to seal off the bottom of the housing, into which the bands fall, to maintain a constant temperature in the housing, and may comprise flexible, slidable, curtain members (90), Fig. 3 (not shown), operated by the supports. The stack bands may be provided with integral buffer members (97), Fig. 10 (not shown), to prevent interference between misaligned adjacent stacks.

Title: Production of metal oxide
IPC: C01B19/00
Filed: 1965-06-11
Abstract: <PICT:1116142/C1/1> A process for producing pigmentary metal oxide and in particular titanium dioxide by the vapour phase oxidation of a metal halide within a closed elongated reactor, which comprises, introducing a stream of metal halide and a stream of oxygen-containing gas into the reactor, obstructing and interrupting the streams of reactant gases by means of a baffle member located within a zone in which reaction takes place, such that the longitudinal axis of the reactor passes through the baffle member and such that the effluent product stream contains less unreacted metal halide than if the baffle member were absent.  Separate concentric streams of vaporous titanium tetrachloride, inert gas and oxygen gas may be fed into the reactor 9 through a series of concentric tubes 1, 2 and 3, the oxygenating stream being introduced at a higher mass velocity than the other streams such that it sucks and merges the lower velocity streams into it.  The concentric tubes may be inclined at an angle of 5 to 85 degrees with respect to the longitudinal axis of the reactor. Small quantities of aluminium trichloride and silicon tetrachloride may be added to the stream of titanium tetrachloride. The inert gas may comprise argon, nitrogen, helium, krypton, xenon and/or chlorine.  The oxygenating gas may comprise O2, NO2, NO or H2O2.  The baffle, which may be of various shapes, may be supported by a hollow tube (11a), Fig. 7 (not shown), containing ports 15 which permit an auxiliary gas for cooling, nucleating and/or further reacting of the product stream to be emitted into the reactor. The auxiliary gas may comprise a recycled gas stream containing unreacted titanium tetrachloride, inert gas, and oxygen or carbon dioxide and/or other products of combustion where CO, natural gas or sulphur containing compounds have been employed as an original source of heat for the reactor.  Additional gas streams may be introduced, e.g. oxygen or nucleating agents such as SiCl4, AlCl3, potassium compounds, and organic compounds. The baffle which may be made of nickel or nickel alloy, may be located at a position near the centre of the reactor but remote from the boundaries of the reactor and in a plane transverse or perpendicular to the flow of reactant gases. Also, it is located at least 0.03 second axial flow time downstream from the point or points of introduction of the reactant gases, has a mean diameter or width of from 0.25 to 0.9 of the mean diameter or width of the reactor and covers 6.25 to 81% of the cross-sectional area of the reactor transverse to the flow of the gas stream.  Other oxides produced by the process include aluminium, arsenic, beryllium, boron, gadolinium, germanium, hafnium, lanthanum, iron, phosphorus, samarium, scandium, silicon, strontium, tantalum, tellurium, terbium, thorium, thulium, tin, titanium, yttrium, ytterbium, zinc, zirconium, niobium, gallium, antimony, lead and mercury.  A series of baffles may be employed.
